Description

Technical Field

[0001] The utility model relates to the field of rail pulley installation, in particular to an automatic plug-in mechanism for a rail pulley device. Background Art

[0002] The rail pulley is mainly used between the beam and the fixed rail, so that the beam can be moved on the fixed rail through the rail pulley. The rail pulley installed on the main beam generally has two types: 8-wheel and 6-wheel.

[0003] Most existing installation methods are to install the rail pulley on the beam body, and then lock it with the rail pulley through the pre-set threaded holes on the beam body. This method can achieve the fixation between the pulley and the beam body, but the threaded locking method is cumbersome to operate. The screws of the rail pulley are easy to rotate during long-term movement, causing looseness between the rail pulley and the beam body. Utility Model Content

[0004] The utility model aims to provide an automatic plug-in mechanism for a rail pulley device, which effectively solves the problem of cumbersome installation by adopting a traditional thread method and also avoids loosening caused by a long time.

[0005] The technical solution of the utility model is as follows:

[0006] An automatic plug-in mechanism for a rail pulley device comprises a trough body and a rail pulley, positioning blocks are arranged on both sides of the rail pulley, a through hole is arranged on the top of the positioning block, a cross-shaped horizontal groove and a vertical groove are arranged in the trough body, the rail pulley is installed in the vertical groove, the positioning block is inserted into the horizontal groove, an inward circular groove is arranged on the tail end wall of the vertical groove, an elastic pin is arranged in the circular groove, and an L-shaped cushion block is arranged at the front end of the elastic pin;

[0007] A vertical downward positioning groove is provided on the bottom wall of the horizontal groove, and the positioning grooves are symmetrically distributed on both sides of the vertical groove. Elastic pins 2 are symmetrically provided on both sides of the rail pulley, and the elastic pins 2 extend vertically downward into the horizontal groove. A limiting column is provided at the bottom end of the elastic pin 2, and the position of the limiting column corresponds to the position of the positioning groove.

[0008] Furthermore, the cross-sectional shape of the horizontal groove and the vertical groove is a rectangle.

[0009] Furthermore, the height of the positioning block is lower than the height of the transverse section of the L-shaped cushion block, and the limiting column can be transferred to the positioning block during the backward movement of the cushion block.

[0010] Furthermore, a lubricating layer is provided on the lower end surface of the limiting column and the upper end surface in contact with the cushion block, so that the positioning pin can slide from the cushion block more easily.

[0011] Furthermore, the length of the elastic pin 1 is not less than the length of the positioning block, so that the limiting column can be inserted into the through hole in the positioning block.

[0012] Furthermore, the limiting column is composed of two sections of cylinders, the upper section of which is larger than the lower section, the upper section of the cylinder matches the size of the through hole, and the lower section of the cylinder matches the positioning groove, so that the limiting column can be inserted into the positioning groove and the through hole to complete the plug-in positioning.

[0013] The advantages of the utility model are:

[0014] 1. The utility model arranges a pad with a spring in the slot body, and the positioning column is placed on the pad. When the rail pulley is inserted into the slot body and moves, the positioning column is separated from the pad, and finally passes through the through hole on the positioning block and enters the positioning slot. Through the docking of the two sections, automatic plug-in positioning is realized. Compared with the traditional thread locking method, the plug-in method is more convenient and faster, and also avoids the loosening caused by long thread locking time.

[0015] 2. The utility model lifts the second elastic pin upwards to disengage the positioning column from the through hole and press it onto the cushion block again, so that the rail pulley can be pulled out of the trough body, which is easier to disassemble than the traditional method.

[0016] 3. The utility model provides an automatic plug-in method, which shortens the installation time and improves the efficiency of rail pulley installation compared to the previous thread locking method. BRIEF DESCRIPTION OF THE DRAWINGS

An inward circular groove 7 is provided on the tail end wall of the vertical groove 6, and an elastic pin 8 is provided in the circular groove 7, and an L-shaped cushion block 9 is provided at the front end of the elastic pin 8;

[0025] A vertical downward positioning groove 10 is provided on the bottom wall of the transverse groove 5, and the positioning grooves 10 are symmetrically distributed on both sides of the vertical groove 6. Elastic pins 11 are symmetrically provided on both sides of the rail pulley 2, and the elastic pins 11 extend vertically downward into the transverse groove 5. A limiting column 12 is provided at the bottom end of the elastic pin 11, and the position of the limiting column 12 corresponds to the position of the positioning groove 10.

[0026] The cross-sectional shape of the transverse groove 5 and the vertical groove 6 is a rectangle.

[0027] The height of the positioning block 3 is lower than the height of the transverse section of the L-shaped cushion block 9 . When the cushion block 9 moves backward, the limiting column 12 can be transferred to the positioning block 3 .

[0028] The lower end surface of the limiting column 12 and the upper end surface in contact with the cushion block 9 are provided with a lubricating layer, so that the limiting column 12 can slide from the cushion block 9 more easily.

[0029] The length of the elastic pin 8 is not less than the length of the positioning block 3 , so that the limiting column 12 can be inserted into the through hole 4 in the positioning block 3 .

[0030] The limiting column 12 is composed of two sections of cylinders, the upper section of which is larger than the lower section. The upper section of the cylinder matches the size of the through hole 4, and the lower section of the cylinder matches the positioning groove 10, so that the limiting column 12 can be inserted into the positioning groove 10 and the through hole 4 to complete the plug-in positioning.

[0031] Detailed usage and effects of the above embodiments:

[0032] When the rail pulley 2 needs to be assembled and installed, first, the rail pulley 2 is installed into the vertical groove 6 inside the trough body 1. The top of the vertical groove 6 is open, and the side wall of the rail pulley 2 has a positioning block 3. The positioning block 3 is inserted into the horizontal groove 5. At this time, the rail pulley 2 is able to enter the trough body 1.

[0033] An elastic pin 2 11 is provided in the vertical slot 6 of the slot body 1, and a limiting column 12 is provided at the bottom end of the elastic pin 2 11. In the initial state, the limiting column 12 is placed on the cushion block 9, the spring inside the elastic pin 2 11 is in a compressed state, and the elastic pin 1 8 connected to the side of the cushion block 9 is in a non-compressed state.

[0034] When the rail pulley 2 is continuously pushed inward, the positioning block 3 will touch the cushion block 9, pushing the cushion block 9 to move backward. When the limiting column 12 is separated from the cushion block 9, it will slide onto the positioning block 3. The limiting column 12 is a cylinder with different diameters at both ends. During continuous pushing, the limiting column 12 will enter the through hole 4 in the positioning block 3, and the elastic pin 11 will spring-reset to move the limiting column 12 downward, and finally the two end cylinders on the limiting column 12 will be respectively inserted into the through hole 4 and the positioning groove 10, thereby realizing the automatic plug-in positioning of the rail pulley 2 and the groove body 1.
