The characteristic of this guide rail is its sliding performance, which can ensure that mechanical parts move smoothly on it, reduce friction and resistance, thereby improving production efficiency and equipment operation stability. Wear resistance means that the surface of the guide rail is made of special materials or processing technology, which makes it have a long service life. Even under long-term and high-frequency sliding friction, it can maintain a low wear rate, thereby reducing maintenance costs and the risk of production interruption;

The application opens a positioning bolt groove inside the guide rail base, sets a positioning bolt hole on the top surface of the guide rail pad, and then threads the outer wall surface of the positioning thread to the inside of the positioning bolt hole, so as to facilitate fixing the bottom surface of the guide rail pad to the ground, adopts a limiting mechanism, solves the stability problem of the sliding guide rail that is easy to splice, and achieves the fixation of the sliding guide rail that is easy to splice.

[0004] During the process of combining and connecting the guide rails of the above-mentioned patent, the first and last guide rails are connected by inserting the splicing block into the splicing position to complete the auxiliary connection, and the fixing process requires bolts to pass through the positioning bolt holes to complete the fixing. The fixing efficiency is low, and there is no connecting structure between the two adjacent guide rails, which can easily cause the distance between the two guide rails to change due to friction, affecting the use of the guide rails.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem that in the process of combining and connecting the first and last guide rails of the existing guide rails, the splicing block is inserted into the splicing position to complete the auxiliary connection, and the bolts need to pass through the positioning bolt holes to complete the fixing process, which has low fixing efficiency, and there is no connection structure between the two adjacent guide rails, which easily causes the distance between the two guide rails to change due to friction, affecting the use of the guide rails, this embodiment provides the following technical solutions:

[0021] A wear-resistant short guide rail that can be connected and extended comprises a guide rail housing 1, a concave thread groove 11 is arranged on one side of the guide rail housing 1, and a protruding connecting rod 4 is arranged on the other side of the guide rail housing 1. Figure 1 , Figure 2 and Figure 3 As shown, the connecting rod 4 is welded and fixed to the guide rail housing 1, and the outer portion of the connecting rod 4 is threadedly matched with the inner thread of the thread groove 11. When two guide rail housings 1 are combined, the connecting rod 4 is inserted into the thread groove 11 inside the other guide rail housing 1 by rotating one of the guide rail housings 1. The spacing between the two guide rail housings 1 and the spacing between the two guide rail housings 1 can be limited later by the limitation of the threaded matching.

[0022] In this embodiment, a connecting groove 9 is arranged around the outside of the thread groove 11, and a recessed movable ring 12 is arranged around the other side of the inside of the guide rail housing 1. Figure 2 , Figure 3 and Figure 4 As shown, a connecting ring 8 is provided inside the movable ring 12, and the outside of the connecting ring 8 is connected to the internal sliding slot of the connecting groove 9. After the two guide rail housings 1 move relatively and approach each other, the connecting ring 8 slides out from the movable ring 12 and can be inserted into the connecting groove 9. The connecting ring 8 limits the rotation of the guide rail housing 1 and the connected connecting rod 4. Limiting the rotation of the connecting rod 4 can fix the distance between the two adjacent guide rail housings 1, thereby improving the stability of the two guide rails when they are connected end to end.

[0023] In this embodiment, a movable rail 6 is provided at the lower end of the movable ring 12. Figure 4 As shown, the movable rail 6 penetrates and extends to the inner and outer ends of the guide rail housing 1, and a connecting handle 7 is arranged inside the movable rail 6. The outer portion of the connecting handle 7 is connected to the inner sliding groove of the movable rail 6. The connecting handle 7 penetrates the movable rail 6 and is welded and fixed to the connecting ring 8. When connecting the two guide rails, the lateral sliding of the connecting handle 7 can adjust the lateral position of the connecting ring 8, so that the connecting ring 8 can extend from the position of the movable ring 12 and be inserted into the connecting groove 9, thereby fixing the rotation of the guide rail housing 1;

[0024] In this embodiment, first magnets 5 are provided at both the front and rear ends and the upper and lower ends of the other side of the connecting ring 8, and the first magnets 5 are fixed to the connecting ring 8 by glue. Figure 3 and Figure 4 As shown, the front and rear ends and the upper and lower ends of the connection groove 9 are both provided with second magnets 10, and the second magnet 10 is fixed to the guide rail housing 1 by glue, the front and rear ends and the upper and lower ends of the movable ring 12 are both provided with third magnets 13, and the third magnet 13 is fixed to the guide rail housing 1 by glue, and the first magnet 5 will contact the third magnet 13 and the second magnet 10 respectively during the lateral movement of the connection ring 8, and the second magnet 10 and the third magnet 13 are both magnetically connected to the first magnet 5, and the adjusted position of the connection ring 8 can be fixed by magnetic connection;

[0025] In this embodiment, a connecting piece 2 is welded and fixedly provided at the lower end of the guide rail housing 1, and extension pieces 3 are welded and provided on both sides of the front and rear ends of the connecting piece 2. Figure 1 and Figure 2 As shown, a through hole is provided inside the extension piece 3, and a threaded wall is provided inside the through hole. After the bolt is rotated inside the through hole to form a threaded fit with the threaded wall, the bolt can be embedded in the installation position to fix the connecting piece 2 and the guide rail housing 1. When the connecting rod 4 and the threaded groove 11 are fixed by bolts, the bolt can be further fixed after passing through the extension piece 3, thereby further improving the stability of the extension piece 3 and the guide rail housing 1.

[0026] Working principle: when using guide rails and combining and connecting them, one of the guide rail housings 1 is rotated by the connecting rod 4 to move toward the threaded groove 11 inside the other guide rail housing 1, and the guide rail housing 1 is rotated. The rotation of the guide rail housing 1 can drive the connecting rod 4 to rotate, and the rotation of the connecting rod 4 and the inside of the contacting threaded groove 11 produce relative movement, and as the guide rail housing 1 continues to rotate, the distance between the two guide rail housings 1 can be gradually reduced. After the distance between the two guide rail housings 1 continues to decrease, the connecting handle 7 is turned, and the connecting handle 7 can drive the connecting ring 8 so that the connecting ring 8 is embedded in the connecting groove 9. After the connecting groove 9 is embedded in the connecting groove 9, the first magnet 5 connected to one end of the connecting ring 8 is magnetically connected to the second magnet 10 to fix the connecting ring 8. The connecting ring 8 is inserted into the connecting groove 9 to limit the rotation of the guide rail housing 1, limit the rotation of the guide rail housing 1 and thus limit the distance between the two guide rail housings 1, and the bolt passes through the extension piece 3 and is embedded in the installation position to fix the combined connecting piece 2.
