In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings. Referring to fig. 1 and 2, an installation positioning structure 10 includes an installation assembly 100 and a positioning assembly 200, where the installation assembly 100 includes a first installation member 110 and a second installation member 120 adjacent to each other, a first positioning hole 111 is formed in the first installation member 110, a second positioning hole 121 is formed in the second installation member 120, and the first positioning hole 111 is communicated with the second positioning hole 121; the positioning assembly 200 comprises a positioning sleeve 210 and a locking member 220, wherein the positioning sleeve 210 is simultaneously arranged in the first positioning hole 111 and the second positioning hole 121 in a penetrating manner, the locking member 220 is arranged in the positioning sleeve 210 in a penetrating manner, a plurality of clamping parts 211 are arranged at one end of the positioning sleeve 210, which is positioned in the second positioning hole 121, and the locking member 220 is used for driving the clamping parts 211 to deform towards the hole wall direction of the second positioning hole 121 so as to clamp and fix the positioning sleeve 210 in the second positioning hole 121.
It should be noted that, the first mounting member and the second mounting member may be mounting plate structures, for example, the first mounting member and the second mounting member are injection molding templates, when the first mounting member 110 and the second mounting member 120 need to be assembled, the first mounting member 110 and the second mounting member 120 are first disposed in a matching manner, so that the first positioning hole 111 is communicated with the second positioning hole 121, and then the positioning sleeve 210 is mounted in the first positioning hole 111 and the second positioning hole 121, so that the first mounting member 110 and the second mounting member 120 can be primarily fixed. After the installation operation of the positioning sleeve 210 is completed, the locking member 220 is installed in the positioning sleeve 210, so that one end of the locking member 220 can be located at each clamping portion 211, and therefore each clamping portion 211 can be spread through the locking member 220, that is, each clamping portion 211 deforms towards the hole wall direction of the second positioning hole 121, so that each clamping portion 211 can be fixed in the second positioning hole 121, meanwhile, the locking member 220 can enable the positioning sleeve 210 to slightly deform in the installation process, and therefore the positioning sleeve 210 is in interference fit with the first positioning hole 111 and the second positioning hole 121, and loose falling of the positioning sleeve 210 can be prevented during the assembly operation. After the assembly operation is completed, the locking member 220 is firstly taken out from the positioning sleeve 210, and then the positioning sleeve 210 is pulled out by the tool such as the toothed pin puller or the nail puller, so that the whole preliminary positioning operation becomes more convenient, and the assembly efficiency and the precision of the mechanical parts can be improved. According to the installation positioning structure 10, the installation assembly 100 and the positioning assembly 200 are arranged, so that the first installation piece 110 and the second installation piece 120 can be initially positioned by adopting the locking piece 220 and the positioning sleeve 210, and the positioning sleeve 210 cannot be loosened or fall off due to vibration in the assembly process of the first installation piece 110 and the second installation piece 120, so that the assembly stability of the whole mechanical part is improved, and the use safety of the whole mechanical part is improved.
Referring to fig. 1 again, in an embodiment, a deformation region 121a is disposed in the second positioning hole 121, and each clamping portion 211 is located in the deformation region, so that after each clamping portion 211 is propped up and deformed by the locking member 220 in the deformation region, the clamping portion can be clamped and fixed in the second positioning hole 121, so that the overall preliminary positioning operation is more stable; for another example, when the locking member 220 is located in the positioning sleeve 210, the expanding head 221 is used for driving each clamping portion 211 to expand in the deformation region 121a, so that in the locking process of the locking member 220, the expanding head 221 can expand each contacted clamping portion 211, so that each clamping portion 211 deforms, and is fixed in the second positioning hole 121; for another example, the clamping portions 211 have a long strip structure, so that each clamping portion 211 can be conveniently opened for deformation operation.
In an embodiment, referring to fig. 2, one end of the clamping portion 211 is provided with a rounded structure, so that the positioning sleeve 210 can be more easily installed in the first positioning hole 111 and the second positioning hole 121, thereby improving the overall production efficiency; for another example, a clearance is provided between two adjacent clamping portions 211, and each clamping portion is annularly distributed around the central axis of the positioning sleeve, so that each clamping portion 211 can have enough deformation space, and the locking piece 220 can better prop up each clamping portion 211.
Referring to fig. 1 and fig. 2, in an embodiment, a threaded hole is formed in a positioning sleeve 210, a locking member 220 is connected with the threaded hole, and the locking member 220 is a locking screw, so that the locking member 220 can be installed on the positioning sleeve 210 in a threaded connection manner, and the disassembly and assembly operations are faster and more convenient; for another example, the first positioning hole and the second positioning hole are counter sunk holes, so that the installation and the pulling-out operation of the positioning sleeve 210 can be facilitated, and the production efficiency is improved; for another example, the positioning sleeve 210 has a cylindrical structure, so that the positioning sleeve can be better matched with the first positioning hole 111 and the second positioning hole 121 in a mounting way.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, which are within the scope of the utility model.
