Description

Technical Field

[0001] The utility model relates to the technical field of improved limit block structures, and specifically relates to an improved limit block structure. Background Technique

[0002] The limit block structure is an "iron block" for restricting positions, which is fixed to relevant parts of the machine tool with screws to control the stroke.

[0003] For example, a limit block structure with the publication number of "CN216545603U", the first flanging is folded downward from the right edge of the plate body, a positioning hole is arranged at the center of the plate body, the limit frame is arranged in the U-shaped groove, the lower edges of the two first flangings overlap on the inner surface of the vulcanized part, and the limit block includes a rubber body whose upper end is connected to the outer surface of the vulcanized part by vulcanization, which can effectively play a role in limiting, buffering and protecting, reduce the damage frequency of the limit block, and reduce after-sales complaints. However, although the limit block structure can buffer during use, the limit block structure still uses the main body for limiting, and it will still be damaged after long-term impacts. It is necessary to disassemble and replace the whole, while other parts are not damaged, resulting in waste, shortening the service life of the limit block structure and increasing the use cost of the limit block structure. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of shortening the service life of the limit block structure and increasing the use cost of the limit block structure, and to propose an improved limit block structure.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design an improved limit block structure, including a limit block and a second bolt. A protection structure is connected above the front surface of the limit block, and installation structures are respectively connected to the left and right sides of the limit block. The protection structure includes a square plate and a concave plate. The outer wall of the square plate is inserted into the notch above the front surface of the limit block, the front surface of the square plate is fixedly connected to the rear end surface of the concave plate, and screw rods are threadedly connected to the inner walls of the square plate and the concave plate.

[0007] Preferably, the rear end surface of the concave plate fits with the front surface of the limit block.

[0008] Preferably, the rear part of the outer wall of the screw rod is threadedly connected to the notch on the front surface of the limit block.

[0009] Preferably, the top of the limit block is threadedly connected to the outer wall of the second bolt.

[0010] Preferably, the installation structure includes a vertical plate and a first bolt. The inner side of the vertical plate fits with the outer wall of the limit block, the inner wall of the vertical plate is threadedly connected to the outer wall of the first bolt, and a bottom plate is fixedly connected to the bottom of the vertical plate.

[0011] Preferably, the inner side of the outer wall of the first bolt is threadedly connected to the outer wall of the limiting block.

[0012] An improved limiting block structure proposed by the present utility model has the beneficial effects that: through the protective structure, the outer wall of the square plate is inserted into the front notch of the limiting block. The square plate can only be inserted into the notch from top to bottom. After the square plate is inserted, the concave plate completely fits on the front of the limiting block. Then, the screw is threadedly passed through the concave plate and the square plate and then threadedly connected to the inner wall of the front notch of the limiting block to complete the installation of the limiting block and the concave plate. The concave plate can prevent objects from directly hitting the limiting block, and the concave plate can be replaced, ensuring the service life of the limiting block structure and reducing the use cost of the limiting block structure.

A protective structure 2 is connected above the front surface of the limit block 1, and mounting structures 3 are respectively connected to the left and right sides of the limit block 1. The protective structure 2 includes a square plate 201 and a concave plate 202. The outer wall of the square plate 201 is inserted into the notch above the front surface of the limit block 1. The square plate 201 can be pushed upward to disengage from the limit block 1. The front surface of the square plate 201 is fixedly connected to the rear end surface of the concave plate 202. Screw rods 203 are threadedly connected to the inner walls of both the square plate 201 and the concave plate 202. The screw rods 203 play a role in fixing the square plate 201, the concave plate 202, and the limit block 1. The rear end surface of the concave plate 202 fits against the front surface of the limit block 1, and the rear part of the outer wall of the screw rod 203 is threadedly connected to the notch on the front surface of the limit block 1;

[0022] By inserting the outer wall of the square plate 201 into the notch on the front surface of the limit block 1 in the protective structure 2, the square plate 201 can only be inserted into the notch from top to bottom. When the insertion of the square plate 201 is completed, the concave plate 202 completely fits against the front surface of the limit block 1. Then, the screw rod 203 is threadedly passed through the concave plate 202 and the square plate 201 and then threadedly connected to the inner wall of the notch on the front surface of the limit block 1 to complete the installation of the limit block 1 and the concave plate 202. The concave plate 202 can prevent objects from directly hitting the limit block 1, and the concave plate 202 can be replaced, ensuring the service life of the limit block structure and reducing the use cost of the limit block structure.

[0023] The top of the limit block 1 is threadedly connected to the outer wall of the second bolt 4. The mounting structure 3 includes a vertical plate 301 and a first bolt 302. The inner side of the vertical plate 301 fits against the outer wall of the limit block 1. The inner wall of the vertical plate 301 is threadedly connected to the outer wall of the first bolt 302. The first bolt 302 plays a role in fixing the vertical plate 301 and the limit block 1. The bottom of the vertical plate 301 is fixedly connected to a bottom plate 303, and the inner side of the outer wall of the first bolt 302 is threadedly connected to the outer wall of the limit block 1.
