Description

Technical Field

[0001] The utility model relates to the technical field of positioning structures, and particularly refers to a shrapnel positioning structure. Background Art

[0002] Shrapnel is mostly used for buffering or fixing in mechanical structures, and a positioning structure is required to fix it during use. However, the existing shrapnel positioning structures mainly include two methods:

[0003] One is to position the shrapnel by means of insertion, but this method cannot fix the position of the shrapnel well;

[0004] The other is to set multiple bending points on the shrapnel and position the shrapnel by setting limiting components at the bending points. The disadvantage of this positioning structure is that the structure is complex and it is not convenient to disassemble, install and replace the shrapnel. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a shrapnel positioning structure with simple structure, good positioning effect and convenient disassembly, installation and replacement of shrapnel in view of the above problems.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a shrapnel positioning structure, including a shrapnel and a positioning seat. A placement groove is provided on the upper end surface of the positioning seat. Connection grooves are provided on both left and right sides of the placement groove on the upper end surface of the positioning seat. A threaded hole is provided at the center of the lower end surface of the connection groove. A shrapnel is provided in the placement groove. An arc-shaped connecting piece is provided at the lower end of the shrapnel, and the arc-shaped connecting piece warps forward. A positioning plate is slidably connected to the upper end surface of the placement groove. A pressing plate is provided at the rear end of the lower end surface of the positioning plate, and the lower end surface of the pressing plate is arc-shaped. The lower end of the pressing plate is cooperatively connected with the arc-shaped connecting piece. Convex blocks are provided at both left and right ends of the positioning plate, and the convex blocks are slidably connected with the connection grooves. Through holes are provided on the convex blocks, and the positions of the through holes correspond to those of the threaded holes. Connection screws are provided in the through holes, and the connection screws are threadedly connected with the threaded holes.

[0007] Further, the back surface of the shrapnel is attached to the back surface of the placement groove, and the back surfaces of the pressing plate and the positioning plate are attached to the front surface of the shrapnel.

[0008] Further, the through holes on the convex blocks are stepped.

[0009] Further, the shape of the convex blocks matches the shape of the connection grooves.

[0010] Further, the back surfaces of the convex blocks are flush with the back surfaces of the positioning plate and the pressing plate.

[0011] Further, the upper end surface of the positioning plate is flush with the upper end surface of the positioning seat.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] 1. The elastic piece is only provided with an arc-shaped connecting piece that warps forward at the lower end. The arc-shaped connecting piece is pressed by a pressing plate with an arc-shaped lower end surface, so as to fix the position of the elastic piece. The fixing effect is good, and there is no need to set up a complex structure, making the disassembly, installation and replacement of the elastic piece more convenient;

[0014] 2. The back surface of the elastic piece fits with the placement groove, and the front surface of the elastic piece fits with the positioning plate. With the cooperation of the positioning plate and the placement groove, the position of the elastic piece in the horizontal direction is also fixed, thus preventing the elastic piece from sliding.

[0025] Combined with the attached Figures 1-4 , a placement groove 3 is provided on the upper end surface of the positioning seat 2. Connecting grooves 4 are provided on the left and right sides of the placement groove 3 on the upper end surface of the positioning seat 2. A threaded hole 5 is provided at the center of the lower end surface of the connecting groove 4. A spring piece 1 is provided in the placement groove 3. An arc-shaped connecting piece 6 is provided at the lower end of the spring piece 1. The arc-shaped connecting piece 6 warps forward. A positioning plate 7 is slidably connected to the upper end surface of the placement groove 3. A pressing plate 8 is provided at the rear end of the lower end surface of the positioning plate 7. The lower end surface of the pressing plate 8 is arc-shaped. The lower end of the pressing plate 8 is cooperatively connected with the arc-shaped connecting piece 6. Convex blocks 9 are provided at the left and right ends of the positioning plate 7. The convex blocks 9 are slidably connected to the connecting grooves 4. Through holes 10 are provided on the convex blocks 9. The through holes 10 correspond to the positions of the threaded holes 5. Connecting screws are provided in the through holes 10. The connecting screws are threadedly connected to the threaded holes 5.

[0026] When positioning the spring piece 1, place the spring piece 1 in the placement groove 3, place the positioning plate 7 on the upper end of the placement groove 3, and the pressing plate 8 on the positioning plate 7 presses the arc-shaped connecting piece 6 that warps forward at the lower end of the spring piece 1. The convex blocks 9 on both sides of the positioning plate 7 are connected to the connecting grooves 4 on both sides of the placement groove 3.
