DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of the utility model protection.

[0029] For example, Figure 1As shown, this utility model includes a mounting plate 1 and a card reader body 2. The mounting plate 1 is fixed to the target position (such as the side wall of the tunnel or the wall) by bolts.

[0030] The card reader body 2 is fixed with a mounting block 21 on the rear side, and the mounting plate 1 is fixed with a connecting seat 3 on the front side. The center of the connecting seat 3 is provided with a square groove that matches the mounting block 21, and the square groove is engaged with the mounting block 21.

[0031] Through holes 31 are respectively provided on the left and right sides of the square groove, and the through holes 31 are located in the inner wall of the connecting seat 3. Each through hole 31 is provided with a limiting mechanism 5, which is used to limit the mounting block 21.

[0032] The top of the card reader body 2 is fixed with a bracket 4, and a protective mechanism 6 is provided on the bracket 4.

[0033] like Figure 2 and 3 As shown, the mounting block 21 has triangular irregularly shaped inserts 23 on its upper and lower sides respectively. On the square groove, corresponding to the irregularly shaped inserts 23, there are irregularly shaped slots 32 that match the irregularly shaped inserts 23. The irregularly shaped inserts 23 are slidably inserted into the irregularly shaped slots 32 respectively.

[0034] The limiting mechanism 5 includes a connecting rod 52, with a spring 54 sleeved on the outer side of the connecting rod 52. A limiting block 51 is fixed to the inner end of the connecting rod 52, and the limiting block 51 is slidably connected to the inner wall of the through hole 31. Limiting grooves 22 matching the limiting blocks 51 are respectively opened on the left and right sides of the mounting block 21, and the limiting grooves 22 are engaged with the limiting blocks 51. A follower plate 53 is fixed to the outer end of the connecting rod 52. The follower plate 53 is located outside the connecting seat 3, and support rods 55 are rotatably connected to both the upper and lower sides of the follower plate 53. A pull ring 531 is provided on the side of the follower plate 53 away from the connecting seat 3. By providing a pull ring 531 on the follower plate 53, it is easier for the operator to operate the limiting mechanism 5, thus improving the convenience of operation.

[0035] By adopting a separate design of the card reader body 2 and the mounting plate 1, and setting a limiting mechanism 5 between the card reader body 2 and the mounting plate 1, the disassembly and assembly of the card reader body 2 are made convenient, eliminating the complicated disassembly and assembly process, saving time and effort, improving disassembly and assembly efficiency, and ensuring the stability and smoothness of mining operations.

[0036] like Figure 4 As shown, the support rod 55 and the follower plate 53 are connected by a rotating shaft. The support rod 55 can rotate within a 90-degree range relative to the side of the follower plate 53 near the connecting rod 52 with the rotating shaft as the center. Each support rod 55 has a square support plate at one end far from the follower plate 53.

[0037] likeFigure 5 As shown, the protection mechanism 6 includes a buffer plate 61 slidably connected with the support 4, the bottom of the buffer plate 61 is provided with two symmetrically arranged elastic buffers 62, the bottom of each buffer 62 is fixed on the top of the card reader body 2, and the telescopic end of each buffer 62 is fixed on the bottom of the buffer plate 61. The top of the buffer plate 61 is further fixed with two symmetrically arranged adapter rods 63, the top of the adapter rod 63 is provided with a guard plate 64, and the top end of each adapter rod 63 is fixed on the bottom of the guard plate 64. The guard plate 64 is in the form of an upwardly protruding arc, and the size of the guard plate 64 is greater than that of the card reader body 2.

[0038] By setting the protection mechanism 6, the damage of the card reader body 2 caused by rockfall impact is prevented, the service life of the card reader body 2 is prolonged, and the stability and smoothness of the mine operation are further ensured.

[0039] The use method of the mine personnel positioning card reader is as follows:

[0040] The mounting plate 1 is fixed at the target position (such as the sidewall of a tunnel or a wall) through bolts, when the card reader body 2 needs to be replaced, the pull ring 531 on one side is pulled to drive the follow-up plate 53 to move outward, the connecting rod 52 drives the limiting block 51 to enter the through hole 31, and the spring 54 is compressed. Then, the support rod 55 is rotated in the direction of the connecting rod 52 at the same time, so that the support plate abuts against the surface of the connecting seat 3, the follow-up plate 53 is fixed at the position at this time, then the pull ring 531 is loosened, the spring 54 continues to maintain the compressed state, and the limiting block 51 is still retracted in the through hole 31. Subsequently, the pull ring 531 on the other side is pulled in the same way, so that the other limiting block 51 is also fixed and retracted in the through hole 31. At this time, the card reader body 2 is directly taken out (so that the mounting block 21 is taken out of the connecting seat 3), and the dismounting work of the card reader body 2 can be completed.

[0041] When the card reader body 2 needs to be installed, the special-shaped plug block 23 is only needed to be inserted into the special-shaped slot 32 in alignment, so that the mounting block 21 enters the square slot of the connecting seat 3. Then the support rod 55 on one side of the connecting seat 3 is restored to the original position (the two support plates are located on the two sides of the follow-up plate 53 and form a straight line), the pull ring 531 is pulled, and under the rebounding force of the spring 54, the pull ring 531 is slowly loosened, so that the limiting block 51 is returned to the original position (the limiting block 51 is inserted into the limiting slot 22). The support rod 55 and the pull ring 531 on the other side are operated in the same way, so that the other limiting block 51 is also restored to the original position (the limiting block 51 is inserted into the limiting slot 22), and the installation work of the card reader body 2 can be completed.

[0042] When the rockfall occurs, the rockfall will drop on the guard plate 64, the guard plate 64 is pushed down to the adapter rod 63 after being impacted, the adapter rod 63 presses down the buffer plate 61, and the buffer 62 at the bottom of the buffer plate 61 buffers the impact force, so that the impact force is offset, and the card reader body 2 is effectively protected.

[0043] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
