Description

Technical Field

[0001] The utility model belongs to the technical field of rack supports, and in particular relates to a rack support component which is easy to assemble and disassemble. Background Art

[0002] The rack support is an important component of the mechanical steering gear assembly. It ensures that the gear rack can mesh better and supports the rack. The rack support and the housing adopt an interference fit, which makes it difficult to disassemble. When encountering parts that need to be repaired or after-sales parts that need to be disassembled and analyzed, it is necessary to use tools to knock on the housing for violent disassembly. In the long run, it affects the service life of the components, causes damage to parts, makes reassembly difficult, and increases the maintenance cost of the rack support. Utility Model Content

[0003] The utility model aims to provide a rack support assembly that is easy to disassemble and assemble, which is convenient and quick to disassemble and assemble, and improves the service life of components. It solves the problem that when the rack support encounters parts that need to be returned for repair or after-sales parts are disassembled and analyzed, it is necessary to use tools to knock on the box for violent disassembly, which affects the service life of components and increases the maintenance cost of the rack support.

[0004] To this end, the technical solution adopted by the utility model is: a rack support assembly that is easy to disassemble and assemble, in which the rack is meshed with the gear size, including a rack support body that matches the outer arc contour of the rack and is interference fit with the housing, the outer wall of the rack support body is provided with mounting grooves at intervals to the left and right and correspondingly installed with "O" rings, and the part of the "O" ring protruding from the outer wall of the rack support body is pressed against the housing, and a center hole is horizontally provided on the side of the rack support body away from the rack, and an annular groove extending vertically outward is provided at the inner end of the center hole, and a clamping tool is provided, so that the clamping tool can be inserted into the annular groove to pull the rack support body out of the housing.

[0005] As a preferred embodiment of the above scheme, a buffer gasket is arranged between the rack supporting body and the rack to prevent wear caused by direct contact between the two components; a buffer gasket positioning hole is horizontally provided in the center of one side of the rack supporting body close to the rack to facilitate the installation and positioning of the buffer gasket; the aperture of the buffer gasket positioning hole is smaller than the aperture of the center hole, and is connected with the center hole on the left and right. The design structure is reasonable to ensure the depth of the buffer gasket positioning hole and the center hole.

[0006] Further preferably, the clamping tool is scissor-shaped as a whole, with a handle at the outer end and a support foot extending vertically outward at the inner end, the support foot is used to extend into the annular groove, and the length is greater than the groove depth of the annular groove, which is ingeniously designed.

[0007] More preferably, the center hole has a diameter of 17 mm to 19 mm and a depth of 13 mm to 14 mm, which are reasonable sizes.

[0008] More preferably, the annular groove has a diameter of 20 mm to 22 mm and a width of 1.5 mm to 1.7 mm, which are reasonable sizes.

[0009] More preferably, the "O"-shaped ring is made of rubber material, and two "O"-shaped rings are arranged at intervals on the left and right, with low material cost, good buffering effect and reasonable quantity.

[0010] Beneficial effects of the utility model:

[0011] (1) Compared with the rack support that needs to be repaired or disassembled and analyzed as an after-sales part, which requires the use of tools to knock on the box for violent disassembly, this solution adopts a center hole for accommodating a clamping tool to be horizontally set on the side of the rack support body away from the rack, and an annular groove is set at the inner end of the center hole. After the clamping tool is inserted into the annular groove, it presses against the inner wall of the annular groove, and the rack support body is pulled outward horizontally to separate it from the box. The design is ingenious, the structure is interlocking, and the rack support body can be disassembled quickly and conveniently without affecting the service life of the components.

[0012] (2) The outer wall of the rack support body is provided with accommodating grooves at intervals to the left and right, and "O"-rings are installed correspondingly, and the part of the "O"-ring protruding from the outer wall of the rack support body is pressed against the box body, thereby achieving an interference fit with the box body. Although it is still an interference fit, due to the partial contact with the box body through the "O"-ring, the stability of the installation with the box body is ensured, and the box body and the rack support body will not be directly in contact with each other during disassembly to generate wear, and the resistance of the clamping tool to pulling and disassembly is effectively reduced. The design is novel and the structure is ingenious.

[0013] In summary, it has the advantages of clever design, interlocking structure, convenient and quick disassembly of the rack support body, no influence on the service life of components, and reduced disassembly resistance of clamping tools. BRIEF DESCRIPTION OF THE DRAWINGS
