[0032] Reference Figure 5The first transmission assembly 4 includes a rotating rod 41, a guide rod 42 and a hinge rod 43. The rotating rod 41 is coaxially fixedly connected to the rotating shaft of the swing arm 21. A slide groove is provided on the rotating rod 41. The slide groove includes a first spiral groove 411, a transverse groove 412 and a second spiral groove 413 which are connected in sequence. The spiral directions of the first spiral groove 411 and the second spiral groove 413 are opposite; the guide rod 42 is fixedly connected to the bracket 2, and a first sliding sleeve 421 is slidably connected to the guide rod 42. A ball bearing that rolls with the sliding groove is arranged in the first sliding sleeve 421; one end of the hinge rod 43 is hinged to the sliding sleeve, and the other end is hinged to the sliding rod 3; refer to Fig.11 The second transmission assembly 5 includes a first rack 51, a gear 52 and a vertical rod 53. The first rack 51 is fixedly connected to the slide bar 3; the gear 52 is rotatably connected in the carrying box, and the gear 52 is coaxially fixedly connected to the turntable 521; the vertical rod 53 is vertically slidably connected in the carrying box, and a connecting plate 531 with a transverse groove 412 is fixedly connected to the vertical rod 53, and a protrusion 6 that abuts and cooperates with the transverse groove 412 is fixedly connected to the turntable 521, and the other end of the vertical rod 53 is fixedly connected to the abutment block 22; refer to Figure 2 The third transmission assembly 7 includes a second rack 71, a push rod 72, an arcuate rack 73 and an elastic member 74. The second rack 71 is vertically slidably connected to the carrying box, and a slide plate 711 is fixedly connected to the second rack 71; the push rod 72 is fixedly connected to the slide bar 3; the arcuate rack 73 is fixedly connected to the hook 23, and the arcuate rack 73 is meshed with the second rack 71; the elastic member 74 restores the deformation process to drive the second rack 71 to slide vertically upward. Specifically, the elastic member 74 includes a spring, one end of the spring is connected to the second rack 71, and the other end is connected to the mounting box 1.

[0033] Before the cover closing tool is used, the cover body and cover of the wire clamp protective cover 101 on the grounding hanging ring (the protective cover 101 is composed of a cover body, a cover and a snap mechanism 8 between the cover body and the cover, and the cover is rotatably connected to the cover body) are in an open state. First, the worker hangs the hook 23 on the carrying box on the grounding hanging ring through the operating rod 31. After confirming that the hook 23 has been hung on the grounding hanging ring, the worker pulls the operating rod 31 and the slide rod 3. In the first stroke of the slide rod 3, the slide rod 3 pulls the first slide sleeve 421 to move along the axial direction of the guide rod 42 through the hinge rod 43, and the movement of the first slide sleeve 421 causes the ball in the first slide sleeve 421 to move with the rotating rod 41. The first spiral groove 411 of the slide bar 3 is first matched, thereby making the rotating rod 41 rotate relative to the bracket 2, and the rotating rod 41 will drive the swing arm 21 to rotate during the rotation process. The rotation of the swing arm 21 forces the cover of the protective cover 101 to close to the cover body until the cover is covered on the cover body. In the first stroke of the slide bar 3, the slide bar 3 will drive the abutment block 22 to slide vertically upward through the second transmission assembly 5. When the slide bar 3 enters its second stroke, during this process, the ball on the first sliding sleeve 421 enters the transverse groove 412 from the first spiral groove 411, thereby making the swing arm 21 remain fixed and motionless, and the slide bar 3 drives the first rack 51 to slide vertically downward relative to the mounting box 1. The sliding of the rack 51 will drive the gear 52 meshing with the first rack 51 to rotate, and the rotation of the gear 52 will drive the turntable 521 coaxially fixedly connected to the gear 52 to rotate, and the turntable 521 will make the protrusion 6 on the turntable 521 to make a circular motion during the rotation process, and the protrusion 6 will abut the connecting plate 531 in the transverse groove 412 of the connecting plate 531, so that the connecting plate 531 moves, and since the vertical rod 53 is vertically slidably connected to the mounting box 1, the connecting plate 531 also moves vertically, and the protrusion 6 abuts the connecting plate 531, thereby causing the vertical rod 53 to move vertically upward, and the abutting block 22 on the vertical rod 53 also moves vertically upward. The inclined surface will abut against the fixed block 81 with the slot 811 on the cover, so that the fixed block 81 is close to the T-shaped plug plate 83. As the fixed block 81 approaches, the plug plate 83 enters the slot 811 of the fixed block 81 and the plug plate 83 abuts the wedge block 82 (the wedge block 82 is slidably connected in the fixed block 81). The wedge block 82 will avoid, and then after being inserted to a certain position, the elastic force of the spring will reset the wedge block 82 and fix the plug plate 83, so that the snap mechanism 8 (the snap mechanism 8 includes the plug plate 83 and the fixed block 81 with the slot 811, the wedge block 82 is slidably connected in the plug plate 83, and a spring is provided between the wedge block 82 and the fixed block 81) is engaged.

[0034] After the installation of the cover body and the lid is completed, the slide bar 3 will continue to slide into the third sliding stroke of the slide bar 3. In the third sliding stroke of the slide bar 3, for the swing arm 21, the ball on the first sliding sleeve 421 enters the second spiral groove 413 from the transverse groove 412, so that the rotating rod 41 rotates, and the rotation of the rotating rod 41 drives the swing arm 21 to rotate in the opposite direction, so that the swing arm 21 is out of contact with the lid, and at the same time, the first rack 51 continues to move to rotate the gear 52, and the gear 52 drives the rotating disk 521 to rotate, and the protrusion 6 on the rotating disk 521 abuts against the connecting plate 531, so that the vertical rod 53 on the connecting plate 531 moves downward, and the abutment block 2 2 slides downward, and the abutting rod 72 on the slide bar 3 abuts against the slide plate 711 to make the second rack 71 slide vertically downward. The second rack drives the arc-shaped rack 73 to rotate during the downward sliding process, and the arc-shaped rack 73 rotates relative to the mounting box 1, which in turn drives the hook 23 to rotate, so that the hook 23 slides from the mounting position to the avoidance position (the mounting box 1 and the hook 23 can be horizontally separated from the grounding ring at the avoidance position of the hook 23). At this time, the swing arm 21 does not contact the cover, the abutting block 22 moves horizontally and does not touch the buckle mechanism 8, and the hook 23 is in the avoidance position. The worker can horizontally move the operating rod 31 to separate the mounting box 1 from the grounding ring.

[0035] Before using the closing tool next time, the swing arm 21, the abutment block 22 and the hook 23 need to be reset. The reset work only requires the worker to slide the slide bar 3 vertically upward. The slide bar 3 drives the swing arm 21 to reset through the first transmission assembly 4 (the swing arm 21 rotates forward and then reverses), and the slide bar 3 resets the abutment block 22 through the second transmission assembly 5 (the abutment block 22 slides vertically upward and then slides downward). After the abutment bar 72 is no longer in contact with the slide bar 3, the elastic force of the elastic member 74 drives the second rack 71 to move vertically upward, and then the arc-shaped rack 73 drives the hook 23 to switch from the avoidance station to the mounting station, completing the reset work of the swing arm 21, the abutment block 22 and the hook 23.

[0036] In the above technical scheme, the present invention provides a cover closing tool for a grounding hanging ring. The worker hangs the mounting box 1 on the grounding ring through the operating rod 31 and the hook 23, and then the worker controls the swing arm 21, the abutment block 22 and the hook 23 by pulling the slide bar 3. During the sliding process of the slide bar 3 relative to the mounting box 1, the slide bar 3 first drives the swing arm 21 forward through the first transmission component 4 to close the cover of the protective cover 101 on the cover body, and then the slide bar 3 continues to slide through the second transmission component 4. The transmission assembly 5 drives the abutment block 22 to slide vertically upward. During the vertical upward sliding process of the abutment block 22, the abutment block 22 engages the buckle between the cover and the lid of the protective cover 101. Finally, the sliding of the slide rod 3 reverses the swing arm 21 through the first transmission assembly 4. The slide rod 3 makes the abutment block 22 slide vertically downward through the second transmission assembly 5. The slide rod 3 switches the hook 23 from the mounting station to the avoidance station through the third transmission assembly 7. The worker can horizontally move the operating rod 31 to make the mounting box 1 detach from the grounding ring.

[0037] The worker controls the positions of the swing arm 21, the abutment block 22 and the hook 23 by controlling the slide bar 3 on the operating rod 31, so that the worker can realize the closing of the cover body and the lid of the protective cover 101, the snap engagement between the cover body and the lid, and the avoidance of the hook 23 without moving the operating rod 31 multiple times, which effectively improves the convenience of the worker's work.

[0038] Among them, the bracket 2 includes a horizontal plate 24 and two support rods 25, the two support rods 25 are fixedly connected to the carrying box, the horizontal plate 24 is fixedly connected to the two support rods 25, the two support rods 25 are slidably connected with a second sliding sleeve 251, and the two second sliding sleeves 251 are fixedly connected to the abutment block 22. Through the sliding cooperation between the two second sliding sleeves 251 and the two support rods 25, the abutment block 22 can move more smoothly during the movement.

[0039] The operating rod 31 is fixedly connected to the slide bar 3 , and the slide bar 3 can be pulled by pulling the operating rod 31 so that the slide bar 3 slides relative to the mounting box 1 .

[0040] As a preferred technical solution of the present invention, there are two rotatably connected hooks 23 on the mounting box 1, and the two hooks 23 are symmetrical with the arc-shaped rack 73. The two hooks 23 can make the mounting box 1 more stably mounted on the grounding ring, and the two hooks 23 are fixedly connected to the arc-shaped rack 73.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
