  For example, in the case of equipment upgrading, it is conceivable that at each upgrade, a part of the equipment is separated from the main equipment at the customer and the board inside the equipment is replaced. The requirement is that the customer can perform the exchange operation, and the separation operation is smooth, and there is work in a situation where the work space is not sufficiently secured, so it is difficult to use a tool with a large or long tool. Even if a special tool is used, if the operation parts are exposed to the outside of the equipment, there is a high possibility that the equipment will be attracted by the customer and receive some operation, and the equipment will be separated against the design intention. It can also cause unnecessary accidents.

  The present invention has been made in view of the above problems, and is provided with a lock mechanism that couples a part of the device to the main device, so that the user does not operate, so that a part that triggers the release of the lock mechanism is not exposed. It is an object of the present invention to provide a device attachment / detachment device that is loaded inside the device and uses a small magnet for the tool used for the unlocking operation.

  The present invention is an apparatus for attaching and detaching a device comprising a first housing and a second housing, wherein the first housing has a guide on one surface thereof, and the second housing is attached to the guide. It has a pair of detachable slides, and one of the first and second housings has a lock mechanism for coupling the guide and the slide, and the lock mechanism device includes the guide and the slide. And a starting plate having a monopolar magnet for releasing the hook, and the hook is released by generating a repulsive force on the magnet of the starting plate from the outside. Is.

  According to the present invention, when the first housing and the second housing are coupled, the magnet of the starting plate inside the device is magnetized from the outside to generate a repulsive force. Since the plate is operated by the repulsive force of the magnet to release the hook, the lock connecting the guide and the slide is released, and the first housing and the second housing can be separated. According to the child device, a user who is not informed of this separation method cannot separate the first housing and the second housing, and therefore can prevent unnecessary accidents.

  Since the start plate of the locking mechanism that locks the coupling between the first and second housings is not exposed to the outside of the device, serviceability is improved without touching the customer easily and design is improved. It leads to improvement. No special tool is required because the repulsive force of the magnet is used when unlocking. Since the strength of the repulsive force depends on the magnetic force of the magnet used as a tool, it can be adjusted by selecting the magnetic force, and can be configured without relying solely on the holding force of the magnet in the device. In the case of joining, it is completed only by fitting without using any special tool. Since there is a starter plate between the hook and the link, it can be reliably detached. Since an electric drive device such as a motor or solenoid is not used, it is advantageous in reducing the power supply capacity, generating no noise, and securing the volume.

The end portion 42 a of the link main body 42 is engaged with the lever 44 and the hook 54 of the hook plate 51. A hook engaging portion 45 capable of locking the combined lever link 41 at a predetermined position is formed. The lever 44 of the lever link 41 is formed by being bent in a U-shaped cross section, and the finger hook portion 44a of the lever 54 is formed on the rear surface of the block 22 in a state where the lever link 41 is locked by the hook plate 51. It is located in the notch portion 23e and is formed so that the surface of the finger hook portion 44a is substantially flush with the rear surface of the block 22. The hook engaging portion 45 of the lever link 41 has a guide portion 55b for guiding the hook hooking portion 45a and the hook releasing portion 64 of the starter plate 61 in a predetermined direction. The adjustment plate 43 to which the lever link 41 is connected is provided with a long groove 43a in the longitudinal direction for moving the movable shaft 76 of the link portion.

  The hook plate 51 is made of a spring plate member, has a hook 54 with a taper formed at an intermediate position between the attachment portion 52 and the movable portion 53, and the attachment portion 62 is a shallow portion provided on the lower surface 23 b of the block 22. It is attached to a groove (not shown).

  The starter plate 61 is made of a spring plate member, and includes an attachment portion 62, an arm 63 formed with a narrow width so as to bend easily, a hook tripping portion 64 formed at the movable end thereof, and a rear surface of the movable end. A disc-like magnet 65 is attached, and a protrusion 64 a for reducing friction with the guide portion 45 b of the lever link 41 is formed on the upper surface of the hook tripping portion 64. The starter plate 61 is attached along the inner surface of the rear edge 23c of the block 22.

It moves in guide grooves 77a and 77b provided in a shaft guide plate 77 (not shown).

  Hereinafter, the operation of attaching and detaching the top box 80 will be described. First, the operation when the separated top box 80 is attached to the base box 10 will be described. When the top box 80 is separated from the base box 10, the lock mechanism 30 is in the state shown in FIG. 6, and the lever 44 of the lever link 41 protrudes rearward from the rear portion of the base box 10. At this time, the movable shaft 76 of the link portion 42 moved in the long groove 43a of the lever link 41 is in the most forwardly moved state, and the locking claw 78 provided at the tip of the link 73 of the link portion 42 is as shown in the figure. Retreats to near the slide surface 83. Accordingly, it can be confirmed that the locking claw 78 is retracted to a predetermined position because the lever 44 of the lever link 41 protrudes rearward from the block 22.

  In this state, the lower surface of the top portion of the top box 80 is placed on the upper surface of the rear portion of the base box 10 and the top box 80 is moved backward so as to fit into the pair of rails 25 of the top box fixing portion 20 in the concave portion 81 on the lower surface of the top box 80. By pushing, the slide surface 82 of the recess 81 is moved along the rail 25. Since the groove 86 and the locking hole 85 are formed in the rear end portion of the sliding surface 82 of the top box 80, the top box 80 moves without being obstructed by the locking claw 78 that has retreated to the predetermined position. When the front wall surface 85 a of the locking hole 85 hits the locking claw 78, the locking claw 78 is pushed by the wall surface 85 a and moves rearward, and the link 83 with the locking claw 78 rotates by the rotation of the link 83. The claw 78 gets up and enters the locking hole 85 and approaches the locked state. Even if the slide surface 82 of the top box 80 is completely fitted to the rail 25, the hook hooking portion 45a of the lever link 41 does not engage with the hook 54, so that the top box 80 is not locked.

  In this state, the lever 44 of the lever link 41 is pushed to lock the top box 80. The lever link 41 rotates against the tension spring 48, and the hook hooking portion 45a of the lever link 41 slides and moves from the taper portion of the hook 54 to fall from the taper portion and engage with the hook 54 as shown in FIG. Become. By rotating the lever link 41, the movable shaft 76 of the link portion 42 connected to the lever link 41 is moved rearward to rotate the pair of links 73 having the locking claws 78, and the locking claws 78 are moved to the locking holes 85. The top box 80 is fixed to the base box 10 in a locked state by moving from the front wall 85a side to the rear wall 83b side.

  Even if the top box 80 is moved forward in this state, since the lever link 41 is engaged with the hook 54, the pair of links 73 having the locking claws 78 do not rotate, so that the lock is released. There is no. At this time, since the hook plate 51 is formed of a spring plate member, the hook hooking portion 45a of the lever link 41 easily moves without applying a bending load when moving on the taper 54a, and the hook hooking portion 45a moves to the taper 54a. The hook 54 can be easily hooked on the hook hooking portion 45a by the return force of the hook plate 51 when exceeding.

  Next, an operation for removing the top box 80 from the combined state will be described. A magnetic force for generating a repulsive force is applied to the magnet 65 from the outside of the device 1 toward a position where the magnet 65 of the starter plate 61 is located. For example, a magnet M (not shown) having the same polarity as the magnet 65 is opposed to the magnet 65 from the outside of the device 1. The magnet 35 transmits a repulsive force with the magnet M to the starting plate 61. As a result, the start plate 61 moves in the recess 26 of the block 22 and the hook tripping portion 64 of the start plate 61 moves to the hook hooking portion 45 a of the lever link 41. Since the hook 54 is tapered, a force is applied in a direction to release the hook hanging portion 45 a, the hook plate 51 is warped and the hook 54 is detached from the hook hanging portion 45 a of the lever link 41. The hook tripping portion 64 of the starter plate 61 is in a narrow gap between the hook plate 51 and the guide portion 45b of the lever link 41, and even if it moves, it does not come out from the middle, so all the movements of the hook tripping portion 64 are all It becomes the releasing force of the hook 54. The lever link 41 is provided with a tension spring 48 that applies tension to the lower end, and a slight force is applied in the release direction. Therefore, when the hook 54 is released, the lever link 41 starts to rotate in the release direction, Even if the initial repulsive magnetic force of the magnet 65 declines and the starter plate 61 returns to the steady position to return to the steady position, it does not move in the reverse direction.

  When the hook 54 is released, the lever link 41 urged by the tension spring 48 rotates and the finger hooking portion 44a of the lever link 41 jumps out slightly from the rear surface of the block 22. Therefore, the lever link 41 is largely rotated in the releasing direction by pulling the finger-hanging portion 44a outward. As a result, the movable shaft 76 of the link portion 42 engaged with the long groove 43a of the lever link 41 moves forward, and the movable end of the link 73 of the link portion 42 rotates, so that the lock at the movable end of the link 73 is locked. The claw 78 rotates so as to push the front wall 85 a of the locking hole 85 forward, and comes out of the hole 85. As a result, the top box 80 can be pulled forward and removed from the base box.
