[0006] In one or more embodiments, a first positioning structure is provided on the inner wall of the installation cavity, and a second positioning structure cooperating with the first positioning structure is provided on the bushing. The first positioning structure cooperates with the second positioning structure to limit the rotation of the bushing.

[0007] In one or more embodiments, the first positioning structure is a positioning convex step, and the second positioning structure is a positioning groove.

[0008] In one or more embodiments, a nut plate is provided in the handle seat, a bushing is provided in the groove with a screw hole, and the fixing screw connects the nut plate and the screw hole.

[0009] In one or more embodiments, the positioning convex step protrudes from the installation cavity, and the handle rod is provided with a notch connected to the positioning convex step.

[0011] In one or more embodiments, a plurality of slots are circumferentially distributed on the outer side surface of the bushing, and the slots extend axially along the bushing.

[0012] Compared with the background technology, the utility model has the following advantages: the handle rod and the handle seat are assembled and connected by the bushing, which has the advantages of simple structure, low production difficulty, low production cost and easy assembly.

Brief Description of the Drawings

[0013] Figure 1 This is a schematic structural diagram of the handle rod, handle seat and bushing in this embodiment. [Specific implementation method]

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0015] Please see Figure 1 The present application provides an assembly structure of a handle rod and a handle seat, which includes a handle rod 1 and a handle seat 2 arranged at both ends of the handle rod. The handle seat is provided with a mounting cavity 3 on the end surface facing the handle rod 1, and a bushing 4 is connected in the mounting cavity. The bushing is specifically inserted into the mounting cavity. The bottom of the handle seat is provided with a fixing screw 5 connected to the bushing. The fixing screw is screwed into the bottom of the handle seat and screwed into the bushing to fix it. At least a part of the bushing extends out of the mounting cavity and is inserted into the handle rod. The handle rod and the handle seat are assembled by plugging, which has the advantages of easy installation and disassembly, simple assembly and high production efficiency.

[0016] The inner wall of the mounting cavity 3 is provided with a first positioning structure, and the bushing 4 is provided with a second positioning structure that cooperates with the first positioning structure. The first positioning structure and the second positioning structure cooperate to limit the rotation of the bushing, which helps to ensure the bushing is aligned when connected to the mounting cavity. Specifically, the first positioning structure is a positioning convex step 6 that extends along the length of the cavity wall of the mounting cavity, and the second positioning structure is a positioning groove 7.

[0017] A nut plate 8 is provided in the handle seat 2, and a screw hole 9 is provided in the groove of the bushing. The fixing screw connects the nut plate and the screw hole. After the fixing screw is connected to the nut plate, it extends into the installation cavity and connects with the screw hole, thereby fixing the bushing and the handle seat together. The provision of the nut plate can effectively prevent the fixing screw from loosening and improve the structural stability of the handle seat and the bushing after assembly.

[0018] The positioning convex step 6 protrudes from the installation cavity 3, and the handle rod 1 is provided with a notch 10 connected to the positioning convex step 6. After the notch is connected to the positioning convex step, the rotation of the handle rod can be restricted, so that the handle rod and the handle seat have better structural stability and a tighter connection after assembly.

[0019] In this embodiment, the handle rod is made of stainless steel or aluminum alloy, the handle base is made of zinc alloy or aluminum alloy or plastic, the bushing is made of zinc alloy or aluminum alloy, and the wall thickness of the aluminum alloy varies from 0.6 to 3 mm, depending on the usage scenario, product requirements, customer requirements and material properties.

[0020] The outer side surface of the bushing 4 is circumferentially provided with a plurality of slots 11 extending axially along the bushing. The provision of a plurality of slots is beneficial to reducing the contact area between the bushing and the handle rod and the handle seat, so as to facilitate better connection between the bushing and the handle seat and the handle rod.

[0021] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
