Description

Technical Field

[0001] This utility model relates to the technical field of mine control boxes, and in particular to a mine ventilation door and window control box. Background Technology

[0002] A mining control box is an electrical device specifically designed for use in harsh underground or surface environments such as mines (including coal mines, metal mines, and non-metal mines) to control, protect, and monitor air doors and windows.

[0003] Some intrinsically safe mine ventilation door and window control boxes adopt an integrated pneumatic-electric structure. Internally, multiple wire harnesses connect the electrical and pneumatic components. For example, Chinese Patent Publication No. CN216700722U discloses a mine explosion-proof control box, including a control box body, a control panel, and electronic components. The control box body is connected to the electronic components via a mounting bracket, and drying components are symmetrically arranged inside. A cabinet door is hinged to one end of the control box body, and the control panel is electrically connected to the electronic components. The cabinet door and the control box body are also connected via a fixing and limiting component. A protective mechanism is provided at the top of the control box body. This invention, through the cooperation of the above mechanisms, can buffer and dissipate the impact force generated by falling objects, providing protection for the equipment and preventing damage from falling rocks. It can also prevent falling rocks from damaging the control panel, ensuring the normal use and service life of the equipment.

[0004] In actual operation, the control box lacks internal wiring harness fixing measures. Without fixing, the wiring harness will shake and rub inside the control box with the vibration of the equipment and the opening and closing of the door, which can easily lead to damage to the insulation layer. In addition, the messy wiring harness is easy to get tangled together during movement or vibration, or get caught or pulled by moving parts (such as fans or door hinges), which makes it less practical. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing control box in which there is no internal wiring harness fixing measures, and to propose a mine ventilation door and window control box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a mine ventilation door and window control box, including a box body and several wiring structures installed inside the box body. The wiring structure includes a connecting part and a fixing part. One end of the connecting part is provided with an elastic clamping part, which is used to clamp and fix the wire harness.

[0008] One end of the fixing part is fixed to the inner side wall of the box, and the other end of the fixing part is slidably connected to the free end of the connecting part, and the height between them is also adjusted by a stop structure.

[0009] Furthermore, the elastic clamping part includes a support part, the support part is fixedly connected to the end of the connecting part, a first arc-shaped clamping part is provided on one side of the end face of the support part, and a second arc-shaped clamping part is rotatably connected to the other side of the end face of the support part.

[0010] The first arc-shaped clamping part and the second arc-shaped clamping part are opposite to each other and staggered, and the wire harness is fixed by clamping them together.

[0011] Furthermore, the first arc-shaped clamping part has a protrusion on its side, and a plurality of positioning grooves are evenly distributed on the inner side of the protrusion. The second arc-shaped clamping part is correspondingly arranged with the protrusion, and the second arc-shaped clamping part extends downward at its free end to form an elastic part. The protrusion of the elastic part is locked in the positioning groove by abutting deformation.

[0012] Furthermore, the end face of the support portion is provided with a clearance groove on the inner side of the protrusion, and the clearance groove is used to avoid the free end of the second arc-shaped clamping portion.

[0013] Furthermore, the stop structure includes a straight groove, the outer wall of the fixing part is connected to the internal cavity to form the straight groove, and a number of stop grooves extend outward from one side of the straight groove, the stop grooves having a T-shaped structure.

[0014] Furthermore, a spring is fixedly connected to one end of the connecting part and the inside of the fixing part, and a guide rod is fixedly connected to the outer wall of the connecting part, and the guide rod is slidably connected in the straight groove;

[0015] The fixing part is rotated to drive the guide rod into the stop groove, and the guide rod can abut against both ends of the stop groove.

[0016] The beneficial effects of the mine ventilation door and window control box proposed in this utility model are as follows: This utility model has several wiring structures installed inside the control box. The wiring structures are used to organize and fix the wire harnesses inside the control box, preventing the wire harnesses from getting tangled or being caught or pulled by moving parts such as fans or door hinges. Among them, a pair of arc-shaped clamping parts can fix wire harnesses of different specifications or quantities within a certain range through the cooperation of positioning grooves and elastic parts. The height between the connecting part and the fixing part can be adjusted. For some wire harnesses that are not easy to bend or have a large directional range, the height of the elastic clamping part can be adjusted to clamp and fix these wire harnesses that are not easy to bend.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A mine ventilation door and window control box includes a box body 1 and a plurality of wiring structures 2 installed in the box body 1. The wiring structure 2 includes a connecting part 21 and a fixing part 22. One end of the connecting part 21 is provided with an elastic clamping part 3, which is used to clamp and fix the wire harness.

[0024] One end of the fixing part 22 is fixed to the inner side wall of the box 1, and the other end of the fixing part 22 is slidably connected to the free end of the connecting part 21, and the height between them is also adjusted by the stop structure 4.

[0025] In some embodiments, for wire harnesses that are not easy to bend or have a large directional range, the height of the elastic clamping part 3 can be adjusted to clamp and fix such wire harnesses that are not easy to bend.

[0026] Furthermore, the elastic clamping part 3 includes a support part 31, which is fixedly connected to the end of the connecting part 21. A first arc-shaped clamping part 32 is provided on one side of the end face of the support part 31, and a second arc-shaped clamping part 33 is rotatably connected to the other side of the end face of the support part 31.

[0027] The first arc-shaped clamping part 32 and the second arc-shaped clamping part 33 are opposite to each other and staggered, and the wire harness is fixed by clamping them together.

[0028] Furthermore, the first arc-shaped clamping part 32 has a protrusion 34 on its side, and a plurality of positioning grooves 341 are evenly distributed on the inner side of the protrusion 34. The second arc-shaped clamping part 33 is correspondingly arranged with the protrusion 34, and the second arc-shaped clamping part 33 extends downward at its free end to form an elastic part 35. The protruding part of the elastic part 35 is locked in the positioning groove 341 by abutting deformation.

[0029] More specifically, the end face of the support portion 31 is provided with a relief groove 36 on the inner side of the protrusion 34, and the relief groove 36 is used to avoid the free end of the second arc-shaped clamping portion 33.

[0030] It should be added that both the first arc-shaped clamping part 32 and the second arc-shaped clamping part 33 are preferably made of materials with deformation capabilities, such as rubber or plastic. Figure 2 As shown, the first arc-shaped clamping part 32 and the second arc-shaped clamping part 33 are both provided with arc-shaped recesses between their opposite sides, and when they are closed and fixed together, the wire harness can be clamped and fixed by the arc-shaped recesses on both sides.

[0031] Specifically, the elastic part 35 is provided with a connecting deformation groove on the protruding part. Through the setting of the deformation groove and the elastic part 35 itself having elasticity, the elastic part 35 is locked in the positioning groove 321, thereby closing and fixing the pair of arc-shaped clamping parts. Of course, external force is required to separate the elastic part 35 and the positioning groove 321.

[0032] More specifically, the protrusion 34 has an arc-shaped structure. Under normal circumstances, when the second arc-shaped clamping part 33 is flipped, the outer side of the second arc-shaped clamping part 33 slides against the inner side of the protrusion 34, and then the protrusion 34 is locked in the positioning groove 321 at different positions, so as to clamp different specifications or different quantities of wire harnesses within a certain range.

[0033] In general, the stop structure 4 includes a straight groove 41, the outer wall of the fixing part 22 is connected to the internal cavity to form the straight groove 41, and a number of stop grooves 42 extend outward from one side of the straight groove 41, the stop grooves 42 having a T-shaped structure.

[0034] Furthermore, one end of the connecting part 21 is fixedly connected to the inside of the fixing part 22 with a spring 43, and a guide rod 44 is fixedly connected to the outer wall of the connecting part 21. The guide rod 44 is slidably connected in the straight groove 41.

[0035] The fixing part 22 is rotated to drive the guide rod 44 into the stop groove 42, and the guide rod 44 can abut against both ends of the stop groove 42.

[0036] In this embodiment, as Figure 3 The connecting part 21 and the fixing part 22 are connected and slidably connected, and the connecting part 21 is outward under the elastic support of the spring 43. However, because the guide rod 44 is stopped in the stop groove 42, the connecting part 21 cannot move freely.

[0037] Specifically, when clamping the wire harness, the connecting part 21 inevitably moves inward due to the force. At this time, the guide rod 44 abuts against the recessed part at the other end of the stop groove 42, and the connecting part 21 can only retract slightly.

[0038] More specifically, by pressing the connecting part 21 inward slightly and then rotating the connecting part 21, the guide rod 44 can slide along the straight groove 41 after disengaging from the stop groove 42. After the guide rod 44 engages with the corresponding stop groove 42, the height of the elastic clamping part 3 can be adjusted.

[0039] Of course, the connection between the stop groove 42 and the straight groove 41 has sufficient length to prevent the inclined guide rod 44 from being unable to disengage from the stop groove 42 or from getting stuck at the connection between the stop groove 42 and the straight groove 41 when the connecting part 21 drives the guide rod 44 to rotate.

[0040] Working method: During operation, the fixing part 22 is fixed on the side wall of the housing 1, and then the height between the connecting part 21 and the fixing part 22 is adjusted according to the arrangement of the electrical and pneumatic wiring harnesses next to it.

[0041] After pressing the connecting part 21 inward slightly and then rotating the connecting part 21, the guide rod 44 can slide along the straight groove 41 after disengaging from the stop groove 42. After the guide rod 44 engages with the corresponding stop groove 42, the height of the elastic clamping part 3 can be adjusted.

[0042] Then, the wire harness is placed in the recess between the first arc-shaped clamping part 32 and the second arc-shaped clamping part 33. The second arc-shaped clamping part 33 is flipped over. When the elastic part 35 is locked in the positioning groove 321, the pair of arc-shaped clamping parts are closed and fixed, thus clamping and fixing the wire harness.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
