[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Reference Figure 1-Figure 5A terminal hanging device with an anti-loosening function includes a support box 10, an L-shaped bracket 17 is fixedly connected to the lower end of the support box 10, and a mounting plate 18 is fixedly connected to the end of the L-shaped bracket 17 away from the support box 10. All parts of the device except the L-shaped bracket 17 and the mounting plate 18 are made of insulating materials. A support seat 11 is slidably installed in the support box 10, and an insulating rotor 16 is provided on the support seat 11. A trigger mechanism is provided in the support box 10, and the trigger mechanism includes two trigger blocks 13 slidably installed on both sides of the inner wall of the support box 10 The lower ends of the two trigger blocks 13 and the lower side of the inner wall of the support box 10 are fixedly installed with a second spring 133. The two ends of the two trigger blocks 13 are provided with a first transmission rod 14 and a second transmission rod 15. The ends of the four second transmission rods 15 that are away from each other all penetrate the support box 10 and are slidably connected to the support box 10. The four second transmission rods 15 are provided with a clamping hole 151 on both sides of the inner wall of the support box 10. The support box 10 is provided with two symmetrically arranged moving blocks 20. The lower ends of the two moving blocks 20 are serrated, which is convenient for increasing the connection with the cable. The friction between the two moving blocks 20 is provided with a moving box 21 on the side away from each other, and the two moving boxes 21 are fixedly connected with two sliding rods 211 on the side away from each other. Second sliding grooves 102 are opened on both sides of the inner wall of the support box 10 just above the four second transmission rods 15. The four second sliding grooves 102 all penetrate the support box 10 and the four sliding rods 211 are slidably installed in the four second sliding grooves 102 respectively. The lower ends of the four sliding rods 211 are respectively engaged with the four card holes 151. There is a second sliding groove 102 between the two moving boxes 21 and the support box 10. There are two locking mechanisms for fixing the positions of the two moving boxes 21. The four second transmission rods 15 move horizontally in the support box 10 under the push of the two trigger blocks 13, and then the four card holes 151 on the four second transmission rods 15 coincide with the lower ends of the four slide bars 211 respectively. Under the action of gravity, the four slide bars 211 penetrate the lower ends of the four slide bars 211 and penetrate the four card holes 151 toward the lower end of the support box 10, so as to drive the lower ends of the two moving blocks 20 on the two moving boxes 21 to be close to the surface of the cable.

[0029] Reference Figure 4 As shown, the locking mechanism includes two fixed boxes 213 fixedly installed on the inner wall of the moving box 21, and the two fixed boxes 213 are arranged at both ends of the fourth spring 24. Blocks 30 are slidably installed in the two fixed boxes 213. The lower ends of the two blocks 30 on one side close to the inner wall of the supporting box 10 are both inclined. A fifth spring 31 is fixedly installed between the two blocks 30 and the inner walls of the two fixed boxes 213. The inner wall of the supporting box 10 is provided with a plurality of card slots 104 at equal intervals directly below the two card blocks 30, and the ends of the two card blocks 30 away from the two fixed boxes 213 are engaged with the plurality of card slots 104.

[0030] Specifically, when the cables in the support box 10 are pulled down, the cables squeeze the support seat 11 and vertically descend in the support box 10. In the process of continuous descent, the support seat 11 will squeeze the two trigger blocks 13 to move vertically downward respectively, so that the ends of the four first transmission rods 14 away from the two trigger blocks 13 respectively push the four second transmission rods 15 to move horizontally at the bottom of the support box 10, so that the four clamping holes 151 on the four second transmission rods 15 coincide with the lower ends of the four slide bars 211 respectively. Under the action of gravity, the two moving boxes 21 respectively drive the four slide bars 211 to move vertically downward, so that the lower ends of the four slide bars 211 pass through the four clamping holes 151 and are in the four clamping holes 15 1, further making the lower ends of the two moving blocks 20 on the two moving boxes 21 close to the surface of the cable on the support seat 11. In the process of the two moving boxes 21 continuing to descend, the inclined surfaces of the lower ends of the four clamping blocks 30 in the two moving boxes 21 move on the plurality of clamping grooves 104. Through the elastic force of the four fifth springs 31, the four clamping blocks 30 move in the plurality of clamping grooves 104. When the lower ends of the two moving blocks 20 are close to the surface of the cable, the four clamping blocks 30 are respectively clamped in the corresponding clamping grooves 104, and the positions of the two moving boxes 21 are locked, so that the cables on the support seat 11 can be fixed to prevent the cables from loosening.

[0031] Reference Figure 1 and Figure 4 As shown, the movable box 21 is provided with connecting holes 212 at the upper ends of the two fixed boxes 213, and the two connecting holes 212 are respectively connected to the two fixed boxes 213, and the upper ends of the two clamping blocks 30 are fixedly connected with U-shaped connecting plates 32, and the connection between the U-shaped connecting plate 32 and the two clamping blocks 30 is respectively slidably connected with the two connecting holes 212, and by pushing the U-shaped connecting plate 32 to move in the two connecting holes 212 in the direction close to the two movable blocks 20, the two clamping blocks 30 respectively squeeze the two fifth springs 31, and further the two clamping blocks 30 are respectively separated from the corresponding two clamping grooves 104, so as to facilitate the release of the fixation of the cable.

[0032] Reference Figure 2 and Figure 3 As shown, a sliding hole 105 is provided on the side of the support box 10 close to the moving box 21, and a connecting box 106 is fixedly connected to the side of the support box 10 away from the moving box 21. The moving box 21 is fixedly connected with a support plate 22 at the middle position of the two sliding rods 211. The support plate 22 passes through the sliding hole 105 and is slidably connected to the sliding hole 105 and the connecting box 106 respectively. A third spring 23 is fixedly installed between the support plate 22 and the lower end of the inner wall of the connecting box 106. The third spring 23 is set in a stretched state. Through the set third spring 23, when the two clamping holes 151 on the two second transmission rods 15 on the same side coincide with the lower ends of the two sliding rods 211 respectively, the elastic force of the third spring 23 pulls the two sliding rods 211 on the moving box 21 to pass through the two clamping holes 151.

[0033] Refer to 2. Figure 3 and Figure 5 As shown, two fixing plates 132 are fixedly connected to the lower ends of both sides of the trigger block 13, one ends of the two first transmission rods 14 are rotatably installed in the two fixing plates 132 at the lower ends of both sides of the trigger block 13, and the other ends of the two first transmission rods 14 are rotatably connected to the two second transmission rods 15, respectively. The two second transmission rods 15 are respectively tightly attached to the lower surface of the inner wall of the support box 10 and are slidably connected to the support box 10. When the trigger block 13 moves vertically downward, it pushes the first transmission rod 14 to reduce the angle between the first transmission rod 14 and the lower surface of the inner wall of the support box 10, and then the first transmission rod 14 can push the second transmission rod 15 to move horizontally in the support box 10.

[0034] Refer to 2 and Figure 3 As shown, a first slide groove 101 is provided on one side of the support box 10 close to the trigger block 13, and a slider 131 is fixedly connected to one side of the trigger block 13 close to the inner wall of the support box 10. The slider 131 is slidably installed in the first slide groove 101. Through the limiting cooperation between the slider 131 and the first slide groove 101, the trigger block 13 can be driven to keep moving vertically downward when the support seat 11 moves downward.

[0035] Reference Figure 1 and Figure 2 As shown, the upper end of the support seat 11 is set as an arc, and a receiving groove 111 is opened on the support seat 11, and an insulating rotor 16 is rotatably installed in the receiving groove 111. First springs 12 are fixedly installed on both sides of the lower end of the support seat 11 and the lower end of the inner wall of the support box 10. Two fixing rods 103 are fixedly installed on the lower end of the inner wall of the support box 10 to prevent the two first springs 12 from bending. The two first springs 12 are respectively slidably sleeved on the outer surfaces of the two fixing rods 103. The support seat 11 has two circular holes just above the two fixing rods 103. The two fixing rods 103 are respectively slidably connected to the two circular holes. The two first springs 12 are set to facilitate the reset of the insulating rotor 16 on the support seat 11 when taking out the cable.

[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the moving block 20 away from the moving box 21 is set as an inclined surface, and limiting grooves 201 are provided on both sides of the moving block 20. Limiting rods 214 are fixedly installed on both sides of the inner wall of the moving box 21. The two limiting rods 214 are slidably connected with the two limiting grooves 201 respectively, and a fourth spring 24 is fixedly installed between the moving block 20 and the inner wall of the moving box 21. Through the limiting cooperation between the two limiting rods 214 and the two limiting grooves 201, the moving block 20 will not deflect when sliding in the moving box 21.

[0037] Specifically, before the cable enters the support box 10, the cable passes through the inclined surfaces on the two moving blocks 20. As the cable continues to move downward, the two sides of the cable move on the inclined surfaces on the two moving blocks 20, so that the two moving blocks 20 move toward the two moving boxes 21 and squeeze the two fourth springs 24 into a compressed state. Then, a gap is generated between the two moving blocks 20, so that the cable falls onto the insulating rotor 16. Then, under the elastic force of the two fourth springs 24, the two moving blocks 20 are brought close to each other and fit together.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
