AI Technical Summary
When existing rocking chairs are rocking, if the swing angle is too large, the bent parts or bolts on the swing arm may easily collide with the support frame, damage the paint and generate noise, affecting the product quality.
An anti-rocking chair base is designed, and an anti-collision piece made of polymer material is connected to the end of the bolt screw, and the anti-collision piece is pressed by the limiting surface to avoid direct contact between the bending part and the limiting surface.
Through the design of the anti-collision parts, the paint attached to both surfaces is protected from damage and reduces noise, thereby improving product quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of home furnishing manufacturing, in particular to an anti-collision rocking chair base. Background Art
[0002] When the existing rocking chair is rocking, if the rocking angle is too large, the bent portion on the rocking arm or the bolts on the rocking arm for fixing the rocking connecting rod are likely to collide with the support frame, which will damage the paint attached to the surfaces of both parties and generate loud noise, affecting product quality. Utility Model Content
[0003] In view of the deficiencies of the prior art, the purpose of the utility model is to provide an anti-collision rocking chair base which can protect the paint attached to both surfaces from being damaged and reduce noise, thereby improving product quality.
[0004] In order to achieve the above purpose, the technical solution adopted by the anti-collision rocking chair base of the utility model is:
[0005] The invention discloses an anti-collision rocking chair base, comprising a bottom frame, support frames are arranged on both sides of the top of the bottom frame, swing arms are arranged on the front and rear sides of the support frame, a bending part is arranged in the middle of the swing arm, the bending part is connected to a swing connecting rod through bolts, the support frame is provided with a limiting surface matched with the bolt and screw, and an anti-collision part made of polymer material is arranged between the limiting surface and the bolt and screw.
[0006] Preferably, the anti-collision member is a bushing sleeved on the end of the bolt screw.
[0007] Preferably, the bushing is interference fit with the bolt and screw rod. During assembly, the bushing is sleeved on the end of the bolt and screw rod, and the swing connecting rod is directly rotated to press the bushing using the limit surface, which is easy to operate and does not require processing threaded holes for the bushing, thereby reducing costs.
[0008] Preferably, the anti-collision member is an edge member installed at the limiting surface, and the edge member can be made of rubber or plastic.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] By adopting anti-collision parts made of polymer materials to avoid direct contact between the bending part and the limiting surface, the paint attached to the surfaces of both sides can be protected from damage, while reducing noise, thereby improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural schematic diagram of the anti-collision rocking chair base of the first embodiment of the utility model;
[0012] Figure 2 yes Figure 1 Enlarged view of point C;
[0013] Figure 3 It is a partial schematic diagram of the anti-collision rocking chair base of the second embodiment of the utility model;
[0014] Among them, 1 is a bottom frame, 2 is a support frame, 21 is a limiting surface, 3 is a swing arm, 31 is a bending part, 4 is a bolt, 5 is a swing connecting rod, and 6 is an anti-collision part. DETAILED DESCRIPTION
[0015] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.
[0016] Embodiment 1, as Figure 1-2 As shown, an anti-collision rocking chair base includes a bottom frame 1, support frames 2 are installed on the left and right sides of the top of the bottom frame, swing arms 3 are pivotally connected to the front and rear sides of the support frame, a bent portion 31 is integrally formed in the middle of the swing arm, the bent portion is fixedly connected to a swing connecting rod 5 by two bolts 4, the support frame is provided with a limiting surface 21 matched with the bolt and screw, an anti-collision member 6 made of polymer material is arranged between the limiting surface and the bent portion, the anti-collision member is a bushing, the bushing is sleeved on an end of a bolt and screw, the bushing is specifically made of nylon, the bushing and the bolt and screw are interference fit, when assembling, the bushing is sleeved on the end of the bolt and screw, the swing connecting rod is directly rotated to press the bushing using the limiting surface, the operation is convenient, there is no need to process threaded holes for the bushing, and the cost is reduced.
[0017] Embodiment 2, as Figure 3 As shown, the difference from embodiments one and two is that the anti-collision component is an edging component installed at the limiting surface, the edging component is an L-shaped nylon component, the short side of the nylon component is in contact with the limiting surface, and the long side of the nylon component can be connected to the support frame by bolts.
[0018] The specific working process and principle of the utility model are as follows: when the swing arm swings back and forth, if the swing angle is too large, the anti-collision part blocks the bolt or the bent part from directly contacting the limiting surface, which can protect the paint attached to the surfaces of both sides from being damaged, while reducing noise, thereby improving product quality.
