A ratchet sofa hinge is easier to identify when the enquiry includes more than a product photo or a general description such as “adjustable sofa hinge.”
Different models may vary in angle, number of positions, diameter, overall dimensions and bracket structure. For B2B sourcing, providing the known specifications at the beginning can reduce unnecessary back-and-forth.
The checklist below explains what information is useful when requesting a quotation.
1. Product Model or Reference Photo
If you already know the model, include the model number in the enquiry.
Xiongfa’s current ratchet sofa hinge range uses model references such as:
If the model is unknown, send clear photos of the existing hinge.
Useful photos include:
- complete hinge
- both sides
- adjustment section
- bracket or plate
- installed position in the sofa, if available
A photo is particularly useful when the hinge structure cannot be described clearly in text.
2. Application
State where the mechanism will be used.
For example:
- adjustable sofa section
- headrest
- armrest
- backrest
- other sofa mechanism
Not every Xiongfa product page currently contains a complete model-specific application description, so the buyer should provide the actual intended application rather than relying only on the product appearance.
3. Angle
If the required angle is known, include it.
Some Xiongfa ratchet sofa hinge models contain explicit angle information.
For example, Model 101 lists angle options including:
45° / 90° / 180°
However, angle information is not available for every current model, so it should only be used when the specification is confirmed.
If you are matching an existing hinge, send the known angle or a drawing rather than estimating from a photograph.
4. Number of Positions or Gears
Some ratchet hinges use multiple locking positions.
Where known, specify the required number of positions or gears.
Model 101, for example, lists:
3 / 4 / 5 gear positions
The number of positions affects how the adjustable section moves through its range.
Do not assume that two hinges with a similar appearance use the same ratchet stages.
5. Diameter
Xiongfa’s current Ratchet Sofa Hinge products contain diameter information.
If you already have an existing mechanism or drawing, include the relevant diameter in the enquiry.
This can help distinguish between hinge models that may look similar in photos.
6. Overall Dimensions
Where available, provide the main dimensions of the existing hinge or required mechanism.
Useful information can include:
- overall length
- plate dimensions
- bracket dimensions
- other measurable structural dimensions
Not every Xiongfa current product contains the same set of dimensional fields, so the buyer should provide the dimensions that are actually known.
For example, Model 103 includes an overall length of 18.5 cm.
A marked drawing or photo is usually clearer than listing several dimensions without showing where they were measured.
7. Bracket, Plate or Rod Structure
Ratchet hinge models may use different structural forms.
If the existing mechanism has a welded bracket, plate, rod or other visible structure, photograph it clearly.
Some Xiongfa products contain partial structural information. For example, Model 114 is a large ratchet hinge with a welded angle-bracket structure.
However, the current public product data does not provide complete mounting geometry for every model.
For that reason, photos should be provided when structure is important to the enquiry.
8. Do Not Guess Mounting-Hole Specifications
The current Xiongfa product data does not provide complete mounting-hole patterns or hole-spacing specifications across the Ratchet Sofa Hinge range.
If these dimensions matter for your project, provide:
- your existing hinge drawing
- marked mounting dimensions
- installation photos
Do not assume that hole spacing can be determined accurately from a product photo.
9. Required Quantity
Include the expected purchasing quantity.
For example:
Model 101, 5 positions, approximately 2,000 pcs.
or:
Existing sofa project, approximately 1,000 pairs. Photos attached for model checking.
If the final quantity is not fixed yet, provide an estimated range.
Example of a Clear Ratchet Sofa Hinge RFQ
A useful enquiry could look like this:
We are looking for a ratchet sofa hinge similar to Model 101.
Application: adjustable sofa section.
Required angle: 90°.
Required positions: 5.
Existing hinge photos and dimensions are attached.
Quantity: approximately 1,500 pcs.
Please check the closest available model and quotation.
What If the Exact Model Is Unknown?
If the model number is unavailable, start with:
photos → application → angle → positions → diameter → known dimensions → structure → quantity
The supplier can then compare the available information with existing models.
Do not guess missing angle, mounting-hole or structural specifications simply to complete the enquiry.
Before Requesting a Quote
For a ratchet sofa hinge enquiry, provide as many of these details as possible:
model → photos → application → angle → positions → diameter → known dimensions → bracket/plate structure → quantity
For more information about angle, positions and size, see the existing Ratchet Sofa Hinge Angle, Positions & Size Guide.
Available models can also be reviewed in the Ratchet Sofa Hinges category before submitting a Request a Quote.
