Description

Technical Field

[0001] The utility model relates to the technical field of production proofing of reclining chairs, in particular to a proofing tooling for reclining chairs. Background Technique

[0002] Before the production of a reclining chair, it is necessary to proof it. The proofing skeleton is made of steel pipe materials. It gives play to the material properties and structural characteristics of the steel pipe. It consists of two upper and lower parts. Removing its support frame can be used as a rocking chair. However, the process of bending stainless steel pipes is difficult, costly, and time-consuming, resulting in low proofing efficiency of the reclining chair. Content of the Utility Model

[0003] To solve the technical problems existing in the background technique, the utility model proposes a proofing tooling for reclining chairs.

[0004] A proofing tooling for reclining chairs proposed by the utility model includes: two oppositely arranged side plates, a plurality of tension springs and a plurality of support rods. A plurality of through holes are arranged at intervals in sequence along the curve direction of the top wall of the upper parts of the two side plates. The tension springs are located between the two side plates and are arranged in one-to-one correspondence with the plurality of through holes. The hooks at both ends of the plurality of tension springs are hooked in the corresponding through holes. The plurality of support rods are detachably installed between the two side plates.

[0005] Preferably, first internal threaded holes are opened at both ends of the support rod, assembly holes are opened on the side plates, and bolts are further included. The screwing end of the bolt can pass through the assembly hole and be screwed with the first internal threaded hole on the support rod.

[0006] Preferably, the length of the support rod is adjustable.

[0007] Preferably, the support rod includes a first rod body part and a second rod body part arranged in sequence along its length direction. A second internal threaded hole is opened at one end of the first rod body part, and an external thread that can be adapted and screwed with the second internal threaded hole is opened at one end of the second rod body part.

[0008] Preferably, the minimum length of the support rod is greater than the length of the tension spring in its natural state.

[0009] Preferably, the spiral directions of the first internal threaded hole and the second internal threaded hole are opposite.

[0010] For the proofing tooling for reclining chairs proposed by the utility model, different spring surfaces with different curves are formed by the tensioned tension springs on the curved surfaces of the top walls of different side plates for experiencing the tooling. According to the human experience, the ideal and comfortable curve is evaluated, which is convenient for proofing and improves the proofing efficiency. Moreover, the support rods and tension springs can be detached and reused, reducing the production cost of the proofing tooling, and the side plates can be used as proofing templates or inspection toolings.

[0012] Figure 2 Front sectional view of a proofing tool for a recliner proposed by the present utility model. Detailed implementation manner

[0013] Referring to Figure 1 A proofing tool for a recliner proposed by the present utility model includes: two oppositely arranged side plates 1, a plurality of tension springs 2 and a plurality of support rods 3. A plurality of through holes 11 are provided in the upper parts of the two side plates 1 at intervals in the direction of the curve of their top walls. The tension springs 2 are located between the two side plates 1 and are arranged in one-to-one correspondence with the plurality of through holes 11. The hooks at both ends of the plurality of tension springs 2 are hooked in the corresponding through holes 11, and the plurality of support rods 3 are detachably installed between the two side plates 1.

[0014] When assembling the proofing tool for the recliner proposed by the present model, the support rod 3 is installed between the two side plates 1, and then the hooks at both ends of the tension spring 2 are hooked in the through holes 11. Different curved surfaces of the top walls of the side plates 1 can form spring surfaces with different curves for experiencing the tool. The ideal and comfortable curve is evaluated according to the human experience, which is convenient for proofing. Moreover, the support rod 3 and the tension spring 2 can be detached for repeated use, reducing the production cost of the proofing tool, and the side plate 1 can be used as a proofing template or an inspection tool.

[0015] In the above embodiment, in order to realize the detachable connection between the support rod 3 and the side plate 1, first internal threaded holes 31 are provided at both ends of the support rod 3, assembly holes are provided on the side plate 1, and a bolt 4 is further included. The screwing end of the bolt 4 can pass through the assembly hole and be screwed with the first internal threaded hole 31 on the support rod 3.

[0016] It should be further noted that in order to meet the proofing requirements of recliners with different widths, the length of the support rod 3 is adjustable. The support rod 3 includes a first rod body part 32 and a second rod body part 33 arranged in sequence along its length direction. A second internal threaded hole is provided at one end of the first rod body part 32, and an external thread that can be screwed with the second internal threaded hole is provided at one end of the second rod body part 33. The length of the support rod 3 can be adjusted by relatively rotating the first rod body part 32 and the second rod body part 33. Specifically, refer to Figure 2 .

[0017] In the above embodiment, the minimum length of the support rod 3 is greater than the length of the tension spring 2 in the natural state, and the spiral directions of the first internal threaded hole 31 and the second internal threaded hole are opposite.

[0018] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
