Description

Technical Field

[0001] This utility model belongs to the field of equipment wiring technology, specifically relating to an anti-loosening wiring structure for coal mine electromechanical equipment. Background Technology

[0002] The wiring connection structure of coal mine electromechanical equipment is an important component to ensure the normal operation of the equipment. With the continuous advancement of coal mining technology, the complexity and automation level of electromechanical equipment are constantly increasing, and the reliability and safety of wiring connections are receiving more and more attention. A reasonable wiring structure can not only improve the working efficiency of the equipment, but also reduce the failure rate and ensure personnel safety. The mine environment is special, with factors such as humidity, dust, and vibration. Therefore, designing and maintaining a suitable wiring connection structure is particularly critical to ensure the stable operation of the equipment under harsh conditions.

[0003] Chinese utility model patent CN210668703U discloses a wiring connection structure for a motor in coal mine electromechanical equipment. The structure includes a terminal block, a wire, and a support rod. A wire-fixing plate is threadedly connected to the side of the support rod away from the terminal block. A housing is threadedly connected to the inner wall of the terminal block. A locking ring is threadedly connected to the side of the housing away from the terminal block. A connector is threadedly connected to the side of the locking ring near the housing. A wire hole is provided on the surface of the connector. This structure, through the connection groove and telescopic column, allows the clamping plate to be first opened by the telescopic column, then the wire inserted into the clamping plate. After releasing, the wire is clamped by a spring. The wire-fixing plate is then rotated and fixed onto the support rod. The housing is then connected to the terminal block. The wire is then inserted into the wire hole of the connector by holding the terminal block, and the locking ring is rotated to fix the housing and connector. This facilitates wiring and improves worker efficiency.

[0004] However, the current structure has the following problems: the connection points in the structure may be loose, resulting in unstable current transmission, poor contact, abnormal equipment operation, or even equipment shutdown. When current passes through, an electric arc may be generated, which may damage the connector and wires, and may also cause fire or equipment damage. Therefore, we propose an anti-loosening wiring structure for coal mine electromechanical equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a non-loose wiring structure for coal mine electromechanical equipment, which can solve the problems in related technologies where the connection may be loose, resulting in unstable current transmission, poor contact, abnormal equipment operation, or even equipment shutdown. When current passes through, an electric arc may be generated, which may damage the connector and wires, and may also cause fire or equipment damage.

[0006] The present invention adopts the following technical solution:

[0007] A non-loosening wiring structure for coal mine electromechanical equipment includes a connector, one end of a connecting shell is threaded to the inner wall of the connector, one end of a connecting ring is threaded to the outer wall of the other end of the connecting shell, and the connector is threaded to the inner wall of the other end of the connecting ring.

[0008] The outer wall of the connecting ring is provided with a fastening mechanism, which includes baffles arranged parallel to each other. The baffles are fixedly connected to the upper and lower parts of the outer wall of the connecting ring, respectively. A placement plate is fixedly connected to the middle of the outer wall of the connecting ring. A bidirectional motor is fixedly connected to the top of the placement plate. The output shaft of the bidirectional motor is fixedly connected to a threaded rod. A threaded sleeve is threadedly connected to the outer wall of the threaded rod. A fixing block is fixedly connected to the outer side of the threaded sleeve. A fixing plate is fixedly connected to the outer side of the fixing block. A fixing rod one is fixedly connected to the outer wall of the connector. A fixing rod two is fixedly connected to the outer wall of the connector. The fixing rod one and the fixing rod two are located on the same side of the fixing plate, and one end of the hinge rod one is hinged to the outer side of the fixing rod one. The other end of the hinge rod one is hinged to the outer side of the fixing plate.

[0009] Furthermore, the threaded sleeve is vertically slidably connected to the round rod, and the two ends of the round rod are respectively fixedly connected to the baffles on both sides.

[0010] Furthermore, the two threaded rods fixed to the output shaft of the bidirectional motor have opposite thread directions.

[0011] Furthermore, a stop mechanism is provided at the top of the baffle, the stop mechanism including a long plate, the long plate being fixedly connected to the top surface of the lower baffle, friction plates being fixedly connected to both sides of the top of the long plate, a connecting block being fixedly connected to the bottom of the lower baffle, vertical plates being fixedly connected to the sides of both the first and second fixed rods, a sliding groove seat being fixedly connected to the side of the vertical plate, a sliding block being slidably connected in the groove of the sliding groove seat, a sliding plate being fixedly connected to the side of the sliding block, one end of the second hinge rod being hinged to the side of the connecting block, the other end of the second hinge rod being hinged to the side of the sliding plate, and the friction plate being located on the displacement trajectory of the sliding plate.

[0012] Furthermore, the connecting shell is made of PBT material.

[0013] This utility model has the following beneficial effects:

[0014] The fastening mechanism, through the cooperation of a bidirectional motor, threaded rod, threaded sleeve, fixing block, fixing plate, hinge rod one, fixing rod one, and fixing rod two, ensures that the connection is secure. This effectively prevents loosening under conditions of vibration, impact, or temperature changes, ensuring stable current transmission, reducing the risk of poor contact, and improving the reliability of equipment operation. The fastening connection also reduces the risk of electric arcing caused by poor contact.

[0015] The stop mechanism, through the cooperation of fixed rod one, fixed rod two, vertical plate, slide groove seat, sliding block, sliding plate, hinge rod two, and sliding plate, generates friction when the sliding plate abuts the friction plate. As the sliding plate continues to move downward, the increased friction prevents the sliding plate from moving outward, thus preventing loosening due to vibration, impact, or temperature changes, improving connection stability, ensuring continuous transmission of current and signals, and reducing the risk of poor contact.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments.

[0023] like Figures 1-3 As shown, a non-loosening wiring structure for coal mine electromechanical equipment includes a connector 1. One end of a connecting shell 2 is threadedly connected to the inner wall of the connector 1. One end of a connecting ring 3 is threadedly connected to the outer wall of the other end of the connecting shell 2. A connector 4 is threadedly connected to the inner wall of the other end of the connecting ring 3. The connector 1 has an internal thread, the connecting shell 2 has external threads at both ends, the connecting ring 3 has an internal thread, and the connector 4 has an external thread.

[0024] The outer wall of the connecting ring 3 is provided with a fastening mechanism 5. The fastening mechanism 5 includes baffles 51 arranged parallel to each other. The baffles 51 are fixedly connected to the upper and lower parts of the outer wall of the connecting ring 3 respectively. A placement plate 52 is fixedly connected to the middle of the outer wall of the connecting ring 3. A bidirectional motor 53 is fixedly connected to the top of the placement plate 52. The output shaft of the bidirectional motor 53 is fixedly connected to a threaded rod 54. A threaded sleeve 55 is threadedly connected to the outer wall of the threaded rod 54. A fixing block 56 is fixedly connected to the outer side of the threaded sleeve 55. A fixing plate 57 is fixedly connected to the outer side of the fixing block 56. A fixing rod 1 58 is fixedly connected to the outer wall of the connector 1. A fixing rod 2 59 is fixedly connected to the outer wall of the connector 4. The fixing rod 1 58 and the fixing rod 2 59 are located on the same side of the fixing plate 57, and one end of the hinge rod 1 510 is hinged to the outer side of the fixing plate 57.

[0025] In this embodiment, the threaded sleeve 55 is vertically slidably connected to the round rod, and the two ends of the round rod are respectively fixedly connected to the baffles 51 on both sides, which can further prevent the threaded sleeve 55 from rotating. The output shaft of the bidirectional motor 53 is fixed to the two threaded rods 54 with opposite thread directions.

[0026] According to the above structure, when the bidirectional motor 53 is started, the output shaft of the bidirectional motor 53 rotates, which drives the threaded rod 54 to rotate. The rotation of the threaded rod 54 drives the threaded sleeve 55 to move in the opposite direction. The movement of the threaded sleeve 55 drives the movement of the fixing block 56. The movement of the fixing block 56 drives the movement of the fixing plate 57. The movement of the fixing plate 57 drives the fixing rod 58 and the fixing rod 59 to move inward through the hinge rod 510, thereby tightening the connection. This can effectively prevent loosening under vibration, impact or temperature changes, ensure stable current transmission, reduce the risk of poor contact, improve the reliability of equipment operation, and reduce the risk of arcing caused by poor contact by tightening the connection.

[0027] like Figure 4 and Figure 5 As shown, a stop mechanism 6 is provided on the top of the baffle 51. The stop mechanism 6 includes a long plate 61, which is fixedly connected to the top surface of the lower baffle 51. Friction plates 62 are fixedly connected to both sides of the top of the long plate 61. A connecting block 63 is fixedly connected to the bottom of the lower baffle 51. Vertical plates 64 are fixedly connected to the sides of both the first fixed rod 58 and the second fixed rod 59. A sliding groove seat 65 is fixedly connected to the side of the vertical plate 64. A sliding block 66 is slidably connected in the groove of the sliding groove seat 65. A sliding plate 67 is fixedly connected to the side of the sliding block 66. One end of the second hinge rod 68 is hinged to the outer side of the connecting block 63. The other end of the second hinge rod 68 is hinged to the side of the sliding plate 67. The friction plate 62 is located on the displacement trajectory of the sliding plate 67.

[0028] According to the above structure, if the connection is loose, the first fixing rod 58 and the second fixing rod 59 move outward, causing the vertical plate 64 to move outward. The outward movement of the vertical plate 64 causes the sliding seat 65 to move outward, which in turn causes the sliding block 66 to move outward. The outward movement of the sliding block 66 causes the sliding plate 67 to move outward. The outward movement of the sliding plate 67, through the second hinge rod 68, causes the sliding plate 67 to move downward. When the sliding plate 67 comes into contact with the friction plate 62, friction is generated. The sliding plate 67 continues to move downward, increasing the friction and preventing the sliding plate 67 from moving outward. This prevents loosening due to vibration, impact, or temperature changes, improves the stability of the connection, ensures continuous transmission of current and signals, and reduces the risk of poor contact.

[0029] In this embodiment, the connecting shell 2 is made of plastic material for insulation and protection, corrosion resistance and lightweight, preventing short circuits and mechanical damage. PBT material is preferred, as it has high electrical insulation and anti-fouling properties.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
