Description

Technical Field

[0001] The utility model relates to a controller box. Background Art

[0002] The mine intrinsically safe controller is used for the protection, control, line communication, fault detection, Chinese character display and language alarm of the fully mechanized mining, fully mechanized excavation working face, chute belt, continuous transport belt conveyor, etc. of the mine.

[0003] The existing mine intrinsically safe controller meets the explosion-proof safety requirements, see Figure 1 , the controller box body 1 and the door 2 (with lock 2-1) are very thick; the box body and the door are connected by hinge 3, and the hinge 3 has a rotation gap. Since the door is very thick (in order to meet the explosion-proof requirements, the thickness is generally at least 10cm), when the door is turned to open, the side of the door away from the hinge ( Figure 1 The right side of the middle door droops due to its own gravity and droops relative to the box body to a certain extent (such as 1-3mm). When the door is closed, there is a relative position misalignment between the door and the box body and it cannot be locked normally. At the same time, the misalignment between the door and the box body reduces the sealing performance. In addition, even if the door and the box body are closed during use, the door and the box body may be misaligned relative to each other under the action of external force, resulting in a weak overall anti-loosening performance. Utility Model Content

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figure 2-3 A controller box includes a box body 1 and a box door 2. One side of the box door 2 is rotatably matched with one side of the box body 1 through a hinge 3. A sealing ring 4 is provided on the open end surface of the box body 1. Specifically, the box door 2 is provided with a lock 2-1. The lock 2-1 belongs to the prior art, so it is not described in detail.

[0030] The key points of this embodiment are:

[0031] The inner bottom side of the box body 1 is located on the side away from the hinge 3 (i.e. Figure 2 A support pad 5 is fixedly provided on the right side of the box door 2, and a ball 6 is rotatably provided on the support pad 5; a lifting plate 7 is fixedly provided on the inner side of the box door 2; when the box door 2 is closed, the lifting plate 7 will be lifted by the ball 6 (see Figure 3 ). Since a rotatable ball is arranged on the support pad 5, when the lifting plate 7 is lifted, no large impact will be generated, the friction is small, and it is very stable and reliable for a long time.

[0032] Specifically, the upper surface of the support pad 5 is provided with a spherical groove 5-1; the ball 6 is installed in the spherical groove 5-1 with clearance and protrudes from the upper surface of the support pad 5, and its protruding height is smaller than the radius of the ball 6. In this way, the ball 6 can rotate in the spherical groove 5-1 and will not run out.

[0033] In this embodiment, the lifting plate 7 includes a vertical plate segment 7 - 1 and a horizontal plate segment 7 - 2 ; the vertical plate segment 7 - 1 is fixedly connected to the inner side surface of the door 2 .

[0034] Specifically, the vertical plate segment 7 - 1 is fixed to the inner side of the door 2 by two screws.

[0035] When the door 2 is closed in a drooping state, the lifting plate 7 will first contact the ball bearing 6, and the lifting plate 7 will be lifted up and corrected to the correct position through the ball bearing 6. Since the door 2 no longer droops after closing, the position of the door 2 and the box body 1 is completely corresponding. In this way, it is ensured that the door 2 and the box body 1 are closed in place when closing, and there will be no relative position misalignment. Therefore, this embodiment can solve the problem of relative position misalignment between the door and the box body of the controller box of the existing mine intrinsically safe controller when closing.

[0036] At the same time, when the controller box is working, the box door and the box body are blocked and limited by the lifting plate 7 and the ball 6 under the action of external force, and relative position dislocation and loosening are not likely to occur, which can improve the overall anti-loosening performance, sealing performance and explosion-proof performance.

[0037] Since the positions of the door 2 and the box body 1 can completely correspond when the door 2 is closed, it can be ensured that the lock 2-1 can be locked normally.

[0038] Embodiment 2: This embodiment is based on embodiment 1 and is further improved:

[0039] See also Figure 4 Two slide grooves 1-1 are symmetrically arranged in the box body 1. Specifically, two slide grooves 1-1 are fixedly installed on the inner bottom side of the box body 1, and the notches of the two slide grooves 1-1 are symmetrical and opposite to each other.

[0040] See also Figure 4 , also includes a skateboard 8; see Figure 2 , wherein a slide plate 8 is slidably connected between the two slide grooves 1 - 1; specifically, the left and right ends of the slide plate 8 are respectively slidably matched with the notches of the two slide grooves 1 - 1.

[0041] See also Figure 4-6 Specifically, a circuit board 9 is mounted on the slide plate 8. The circuit board 9 is detachably fixed on the slide plate 8 by bolts. In this way, the circuit board 9 can be detached and replaced, which is convenient for maintenance.

[0042] Furthermore, the slide plate 8 is provided with a handle 11 on the side facing the box door 2. When the product is produced, the slide plate 8 and the circuit board 9 thereon can be easily pushed into the box body 1 through the handle 11 after being inserted into the notches of the two slide slots 1-1 of the box body 1, and the whole assembly can be completed quickly, which can improve the assembly efficiency (see Figure 1 When replacing or repairing, the slide plate 8 and the circuit board 9 thereon can be slid out of the notches of the two slide grooves 1-1 of the box body 1 by pulling the handle 11 outward, so as to realize the quick removal of the whole (see Figure 4 ), the circuit board and the electrical and electronic components configured thereon are exposed, making it easy to repair and replace.

[0043] Furthermore, the handle 11 can be stored on the slide 8. Since the handle 11 becomes smaller after being stored, it occupies less space, and the size of the box can be reduced, saving costs. Specifically, the front end of the slide 8 is provided with two connecting parts 8-1, and the handle 11 is a C-shaped handle. The two connecting ends of the handle 11 are rotatably connected to the two connecting parts 8-1 respectively. In this way, the handle 11 will be turned to a horizontal state when it is needed (see Figure 5 ), when the handle 11 is stored, it is turned to a vertical state (see Figure 5 ). It is very convenient to use.

[0044] Furthermore, a clamping mechanism 10 is provided on the slide plate 8 to prevent the capacitor 9 - 1 plugged into the circuit board 9 from loosening.

[0045] See also Figure 4-7 Furthermore, the clamping mechanism 10 includes a front screw 10-1, a rear screw 10-2 and a pressing plate 10-3; the front screw 10-1 and the rear screw 10-2 are both vertically arranged and symmetrically distributed at front and rear intervals; the lower end of the front screw 10-1 is fixedly connected to the front end of the slide plate 8; the lower end of the rear screw 10-2 is fixedly connected to the rear end of the slide plate 8; the upper end of the front screw 10-1 passes through the front end of the pressing plate 10-3 and is threadedly connected to the front nut 10-4; the upper end of the rear screw 10-2 passes through the rear end of the pressing plate 10-3 and is threadedly connected to the rear nut 10-5.

[0046] During assembly and pressing, the front end of the pressing plate 10-3 can be forced to move downward by rotating the front nut 10-4, and the rear end of the pressing plate 10-3 can be forced to move downward by rotating the rear nut 10-5, until the pressing plate 10-3 is pressed against the capacitor 9-1. The existing capacitor 9-1 is inserted on the circuit board 9. This can prevent the capacitor 9-1 from loosening and stabilize the circuit. At the same time, the front nut 10-4 and the rear nut 10-5 can be used to adjust the tightness, which is very flexible.

[0047] In this embodiment, there are two clamping mechanisms 10 which are spaced apart from each other.

[0048] Embodiment 3: This embodiment is based on embodiment 2 and is further improved:

[0049] See also Figure 7 Furthermore, an elastic pad 10-6 is provided on the lower surface of the pressure plate 10-3, and the elastic pad is in elastic contact with the capacitor 9-1 to avoid damage.
