Description

Technical Field

[0001] The utility model relates to the technical field of grounding hooks, in particular to an improved grounding hook structure which can be quickly assembled and disassembled. Background Art

[0002] In overhead line maintenance work, power outage maintenance measures are indispensable, among which hanging the ground wire and removing the ground wire after the work is completed are the key links to ensure the safety of the work. This process takes up a considerable part of the "skylight" time of the maintenance work, especially for maintenance work in complex environments such as stations. Traditional ground hooks, such as Figure 1 As shown, it consists of a slide bar a, a clamping end b and a nut c, wherein one end of the slide bar a is fixed with a bolt d, and there is a C-shaped groove e between the clamping end b and the end of the slide bar a that is adapted to the cross-sectional shape of the rail. The clamping end b can slide along the slide bar a, and the clamping end b is fastened to the rail by tightening the nut c and the bolt d, and the other end of the slide bar a is used to connect the grounding wire.

[0003] However, the existing traditional grounding hooks have exposed the following problems in long-term use:

[0004] 1. After long-term repeated use, the threads on the grounding hook bolt are prone to wear and thread slippage, resulting in the nut being unable to be effectively tightened, thus affecting the grounding effect and posing a safety hazard.

[0005] 2. The installation and disassembly process of traditional grounding hooks is rather cumbersome, requiring the use of wrenches and other tools to tighten and loosen the nuts. This process is not only time-consuming and labor-intensive, but may also delay the progress of the operation in an emergency and increase the difficulty of operation.

[0006] 3. Due to the design of the grounding wire connector, the connection between the connector and the bolt is at a 90° right angle. During use, the grounding wire will be folded, damaged, and broken.

[0007] In view of this, the inventor specially designed an improved grounding hook structure that can be quickly assembled and disassembled, and this case was thus produced. Utility Model Content

DETAILED DESCRIPTION

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, 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.

[0046] Embodiment 1

[0047] See also Figures 2 to 8 , is an improved grounding hook structure that can be quickly assembled and disassembled as the best embodiment of the utility model, comprising:

[0048] The slide bar 10 has a C-shaped slot 12 at one end adapted to the cross section of the bottom end of the rail 70, and a wiring structure 20 detachably connected to the ground wire 80 at the other end;

[0049] The moving rod 30 has a sliding sleeve 35 at the lower end thereof disposed on the sliding rod 10, and a ratchet structure 31 distributed along an arc path is disposed at the top thereof, and a rotating shaft 32 is disposed around the arc center of the ratchet structure 31;

[0050] The operating member 40 is hinged to the rotating shaft 32 and has a cam structure 41 and a control handle 42 formed at two ends based on the rotating shaft 32;

[0051] The clamping sleeve 50 has a U-shaped connecting end 51 and a slot end 52 opposite to the opening of the connecting end 51 and opposite to the opening of the C-shaped slot 12. Linear movable slots 53 are symmetrically formed on both sides of the connecting end 51. The operating member 40 and the clamping end are limited between the two sides of the opening of the connecting end 51 and the two ends of the rotating shaft 32 pass through the movable slots 53 so that the connecting end 51 can move relative to the rotating shaft 32. In this embodiment, another C-shaped slot 12 opposite to the opening of the C-shaped slot 12 and having the same shape is opened on the side of the slot end 52 close to the C-shaped slot 12. The C-shaped slots 12 referred to in this embodiment are all of a shape that is adapted to the cross-sectional shape of the bottom of the rail 70.

[0052] The control button 60 is hinged to the control handle 42 of the operating member 40 through a hinge shaft 63, and the two ends of the hinge shaft 63 are respectively formed with a ratchet end 61 and a pressing end 62 that cooperate with the ratchet structure 31, and an elastic member 64 is provided between the pressing end 62 and the control handle 42 for elastically supporting the pressing end 62 so that the ratchet end 61 is buckled on the ratchet structure 31 and the pressing end 62 at least partially protrudes from the end surface of the control handle 42;

[0053] Among them, the distance between the farthest end of the cam structure 41 and the center of the rotating shaft 32 is greater than the maximum distance between the inner side of the opening of the connecting end 51 and the rotating shaft 32 so that when the control handle 42 is rotated relative to the rotating shaft 32 against the ratchet limit direction, a farthest position of pushing the connecting end 51 away from the rotating shaft 32 can be obtained.

[0054] Specifically, Figure 4 As shown, the cam structure 41 is a protrusion with an arc-shaped cam end, and the maximum distance between the protrusion and the center of the rotating shaft 32 is D1. When the connecting end 51 is supported by the cam structure 41, it moves along the extension direction of the movable groove 53 and in the direction close to the other C-shaped slot 12 with the moving rod 30 as a reference. When it moves to the other side of the movable groove 53 and is limited by the rotating shaft 32, a maximum distance D2 is formed between its inner wall and the center of the rotating shaft 32. At this time, D2 is less than D1. Therefore, when the control handle 42 of the operating member 40 is rotated, the cam structure 41 can rotate around the rotating shaft 32 to push the connecting end 51 away from the moving rod 30 and move it toward the other C-shaped slot 12. At this time, the contact point between the bottom of the moving rod 30 and the sliding rod 10 is used as a fulcrum to achieve the purpose of clamping the bottom of the rail 70 from both sides.

[0055] Preferably, Figure 2 , 3 As shown, a bending section 11 is vertically provided at one end of the sliding rod 10 , a C-shaped slot 12 is welded and fixed on the top of the bending section 11 and opens toward the wiring structure 20 , and the moving rod 30 is arranged parallel to the bending section 11 .

[0056] Preferably, Figure 4 , 5As shown, a through slot 43 is vertically provided on one side of the operating member 40 close to the cam structure 41, and the moving rod 30 passes through the through slot 43 vertically. The rotating shaft 32 passes through one side of the through slot 43 and passes through the moving rod 30 in turn and then passes out along the other side of the through slot 43. In this way, the moving rod 30 can be clamped and installed on the inner side of the operating member 40, so as to facilitate cooperation with the control button 60.

[0057] Preferably, Figure 4 , 5 As shown in FIG. 1 , the connecting end 51 includes two side plates 511 that are relatively distributed and a connecting plate 512 that connects the common sides of the two side plates 511. The connecting plate 512 and the two side plates 511 enclose a "U"-shaped opening groove 513. The rotation position of the moving rod 30 and the operating member 40 is accommodated in the opening groove 513. The movable groove 53 is a linear waist groove symmetrically arranged on the side walls of the two side plates 511. The opening size of the waist groove is adapted to the diameter of the rotating shaft 32. The waist groove is parallel to the opening of the slot end 52. Direction distribution, thus, by installing the side plates 511 on both sides of the connecting end 51 on the side walls of the operating member 40, the cam structure 41 can be easily included in the opening groove 513 of the connecting end 51, so that by rotating the control handle 42, the cam structure 41 can be easily pressed against the inner wall of the opening groove 513, so that the connecting end 51 drives the slot end 52 to move in the direction close to the rail 70, and cooperates with the C-shaped slot 12 at the other end of the slide rod 10 to further press and connect the rail 70.

[0058] Preferably, Figure 4 , 5 As shown, the end surface of the control handle 42 is provided with a mounting groove 421 for the control button 60 to move, and the elastic member 64 is a reset spring movably arranged between the bottom of the mounting groove 421 and the pressing end 62.

A limiting sleeve 422 is provided at the inner bottom of the mounting groove 421 and at a position opposite to the limiting groove 622. The upper end of the limiting sleeve 422 is provided with an opening for accommodating the reset spring. The limit groove 622 and the limit sleeve 422 can limit the return spring between the inner bottom of the installation groove 421 and the inner bottom of the pressing end 62, so that the pressing end 62 can always provide elastic support for the pressing end 62, so that the pressing end 62 can rotate relative to its hinge shaft 63, thereby pressing the pawl end 61 onto the ratchet structure 31, and making the pressing end 62 partially protrude from the outer side of the end surface of the control handle 42, so as to facilitate the user to press the pressing end 62.

[0059] Preferably, Figure 2 , 3As shown, the portion of the pressing end 62 protruding from the end surface of the control handle 42 is provided with a locking hole 623 which runs horizontally therethrough, and the position of the locking hole 623 is set so that when the pressing end 62 is lifted up by the elastic member 64, the locking hole 623 is exposed outside the control handle 42. In the present embodiment, the locking hole 623 is located close to the position where the pressing end 62 is exposed from the pressing handle, that is, only a little pressing distance is reserved which is not enough to allow the pawl end 61 to disengage from the ratchet structure 31, so that the pressing end 62 can be limited by a locking rod, a locking rope or other structures which can pass through the locking hole 623 to prevent the pressing end 62 from pressing down, thereby preventing the pressing end 62 from being accidentally touched and causing the pawl end 61 to disengage from the ratchet structure 31, thereby preventing the slot end 52 from falling off the bottom of the rail 70.

In this embodiment, the ratchet structure 31 is a plurality of ratchets distributed clockwise around the rotating shaft 32, and the limiting direction of the plurality of ratchets is counterclockwise. At this time, the pressing end 62 is located at the upper end surface of the control handle 42. When the control handle 42 is pressed downward relative to the rotating shaft 32, the pawl end 61 rotates clockwise around the ratchet structure 31, and the pawl end 61 is not blocked. , that is, the process of the cam structure 41 pressing the clamping sleeve 50 is not limited, thereby facilitating the installation process of the grounding hook; on the contrary, when the control handle 42 is lifted relative to the rotating shaft 32, the pawl end 61 rotates counterclockwise around the ratchet structure 31, and the pawl end 61 is in the limiting direction of the ratchet, and the control handle 42 cannot be lifted, that is, the process of releasing the cam structure 41 from tightening the clamping sleeve 50 is limited, and it is necessary to press the pressing end 62 to release the limitation of the pawl end 61 and the ratchet before continuing to lift the control handle 42, so that the slot end 52 is removed from the bottom of the rail 70, facilitating the removal of the grounding hook.

[0061] In this embodiment, the control button 60 is disposed at the upper end of the control handle 42 , which is one implementation method that conforms to the human hand operation habits.

[0062] Preferably, Figure 6 , 7 As shown, the grounding structure includes a connecting sleeve 21 integrally fixed to the end of the sliding rod 10 and a connecting member 22 detachably connected to the connecting sleeve 21. The end of the connecting member 22 is provided with a plug-in end 23 which is plugged and limited with the connecting sleeve 21. The plug-in end 23 is electrically connected to the grounding wire 80.

[0063] Specifically, the interior of the connecting sleeve 21 is concavely provided with a cylindrical plug-in groove 24 distributed along the length direction of the slide rod 10, the plug-in end 23 is a columnar shape that is clearance-matched with the cylindrical plug-in groove 24, and a limit end 231 is formed at its bottom that protrudes radially from its peripheral side surface, and the side wall of the plug-in groove 24 is provided with an L-shaped clamping groove 25 that extends along its opening to the inner bottom, and the clamping groove 25 includes a vertical section 251 and a horizontal section 252, the lateral spacing of the vertical section 251 is adapted to the width of the limit end 231, and the height of the horizontal section 252 is adapted to the limit The height of the end 231 is adapted to that of the end 231, so that the limit end 231 is aligned with the opening of the card slot 25 and inserted. When the limit end 231 moves downward along the vertical section 251 of the card slot 25, the plug-in end 23 moves downward along the plug-in slot 24 as a whole. When it moves to the bottom, the plug-in end 23 is rotated so that the limit end 231 moves horizontally into the horizontal section 252 to complete the connection of the plug-in sections. At this time, a limit is formed between the limit end 231 and the upper and lower side walls of the horizontal section 252 to prevent the plug-in end 23 from falling out, thereby facilitating the connection between the grounding wire 80 and the grounding hook.

[0064] The connecting sleeve 21 is made of insulating material such as rubber, etc., so as to facilitate operation by maintenance personnel.
