Description

Technical Field

[0001] The present application relates to the technical field of high-voltage line maintenance equipment, and in particular to a portable line insulation protection umbrella. Background Art

[0002] With the rapid economic development, the power supply load of the State Grid is growing day by day. 10kV overhead lines are spread all over the streets and alleys in the city, and there are many hidden dangers in the safety of electricity use. In recent years, the State Grid Corporation has put the upgrading of overhead lines in the city underground and the renovation of old overhead lines on the agenda. The work of dismantling and replacing overhead lines is imminent. When dismantling and modifying the lines, it is often necessary to protect the construction workers with devices such as umbrellas.

[0003] At present, during the installation of pole-mounted switches, construction workers mainly install insulating umbrellas at a distance of 0.7 meters from the live body by climbing poles to further control the workers to be outside a safe distance. However, the existing protection devices need to be carried to the poles close to the top of the line for installation. They need to be connected by bolts, and the operators are at high altitude for installation. Due to the large size of the device, it is not convenient to carry when climbing, and the movement is restricted during high-altitude installation, resulting in poor safety.

[0004] Therefore, the present invention proposes a portable line insulation protection umbrella. Summary of the invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and the application provides a portable line insulation protection umbrella.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A portable line insulation protection umbrella, comprising: The upper hoop plate comprises two upper half hoop plates, wherein an arc groove is provided on the upper half hoop plates, a sliding plate is slidably installed in the arc groove, and teeth are installed on the sliding plate, wherein a rotating plate is rotatably installed on one of the upper half hoop plates, and protruding teeth meshing with the teeth are installed on the rotating plate, a groove is provided on the sliding plate, and a convex block is slidably installed on the upper half hoop plates through a connecting spring, and the convex block is used to be inserted into the groove on the adjacent sliding plate; The lower hoop plate comprises two lower half hoop plates, the structure of the lower half hoop plate is consistent with that of the upper half hoop plate, the lower half hoop plate and the upper half hoop plate are hinged with umbrella ribs, and the umbrella surface is installed on the free end of the umbrella ribs. When the lower hoop plate approaches the upper hoop plate, the free end of the umbrella rib drives the umbrella surface away from the lower hoop plate and the upper hoop plate; A fixing part includes a mounting plate mounted on an upper hoop plate or a lower hoop plate, a resistance plate being hinged on the mounting plate, a vertical plate being slidably mounted on the mounting plate, an inclined block for resisting the resistance plate being mounted on the vertical plate, a pull rope being mounted on the resistance plate, a free end of the pull rope being connected to the upper hoop plate or the lower hoop plate, an L-shaped rod being mounted on the sliding plate, and when the sliding plate slides, the L-shaped rod pulls the pull rope, forcing the inclined block to resist the resistance plate, so that the resistance plate resists the electric pole.

[0007] Furthermore, arc grooves are provided on the upper hoop plate and the lower hoop plate, a hard block is installed on the free end of the pull rope, the hard block is slidably matched with the arc groove, and a resistance spring is installed between the vertical plate and the mounting plate.

[0008] Furthermore, a mounting sleeve is installed on the rotating plate located on the upper half hoop plate, and a driving rod that passes through the rotating plate is movably inserted on the rotating plate located on the lower half hoop plate, and the driving rod is used to be inserted in the mounting sleeve. A limiting groove is opened on the driving rod, and a limiting block that slides with the limiting groove is installed in the mounting sleeve.

[0009] Furthermore, the umbrella ribs include an upper main rod, a lower main rod, a connecting rod and a mounting rod. The upper main rod is hinged on the upper half hoop plate, the lower main rod is hinged on the lower half hoop plate, the free end of the upper main rod is hinged to the rod body of the lower main rod, one end of the connecting rod is hinged to the rod body of the upper main rod, and the other end is hinged to the rod body of the mounting rod, one end of the mounting rod is hinged to the free end of the lower main rod, and the mounting rod is used to connect to the umbrella surface, and a accommodating sleeve is installed on the rotating plate, and accommodating sleeves are also installed on the upper main rod and the lower main rod close to the rotating plate. When the driving rod is inserted into the accommodating sleeve, the rotation of the rotating plate is restricted.

[0010] Furthermore, a sleeve rod is rotatably mounted on the lower hoop plate, an insertion rod is slidably mounted in the sleeve rod via a compression spring, a sleeve ring is mounted on the driving rod, and the insertion rod is used to be inserted in the sleeve ring.

[0011] Furthermore, a baffle plate is hinged on the upper hoop plate and the lower hoop plate, and a pushing rod is installed on the upper main rod and the lower main rod. When the lower hoop plate approaches the upper hoop plate, the upper main rod and the lower main rod drive the pushing rod to resist the baffle plate, so that the projection of the baffle plate on the upper hoop plate or the lower hoop plate blocks the sliding plate.

[0012] Furthermore, an oil tank is installed on the upper hoop plate and the lower hoop plate, and the oil tank has an opening. An oil inlet hole connected to the oil tank opening is opened in the arc groove. A block for covering the oil tank opening is slidably installed on the oil tank through a return spring, one end of the block passes through the oil tank and is located on its upper surface, and an expansion panel for contacting with the protruding teeth is installed on the block.

[0013] Furthermore, a guide block is installed in the oil tank, and a slope facing the oil tank opening is formed on the guide block.

[0014] Furthermore, a stop plate is installed in the arc groove, and when the sliding plate slides to contact with the stop plate, the sliding plate is at the maximum sliding range.

[0015] Furthermore, an arcuate surface is formed at the end of the insertion rod, and the insertion rod contacts the side wall of the collar through the arcuate surface.

[0016] The beneficial effects of this application are as follows: 1. When in use, the present application aligns the two upper half hoop plates, and rotates the rotating plate so that the protruding teeth thereon drive the sliding plate to slide through the teeth, so that the abutting sliding plates on the two upper half hoop plates are respectively inserted into the arc grooves on the opposite sides, and the protruding blocks are inserted into the grooves to limit the sliding of the sliding plates. The lower hoop plates are also operated in the same way, so that the upper hoop plates and the lower hoop plates are formed. During the process, the pull rope pulls the inclined block to contact the abutting plate through the pulling of the L-shaped rod, so that the two can contact the electric pole, thereby increasing the installation strength of the device. When connecting the device, the lower hoop plate is moved closer to the upper hoop plate to open the umbrella cover. When in use, the device can be installed in advance through the telescopic clamp rod carried during construction, thereby increasing the safety of the device when in use.

[0017] 2. In the present application, when in use, the free end of the pull rope can slide in the direction away from the mounting plate, so that when the pull rope is resisted by the L-shaped rod, the vertical plate is pulled by displacement instead of being deformed by itself, thereby increasing the service life of the pull rope. In this embodiment, the pull rope can be made of hemp rope or iron chain, which has poor deformation performance but is solid and wear-resistant, thereby increasing the safety of the device when in use, and the resistance spring forces the inclined block to move away from the mounting plate, so that the resistance plate will not resist the pole during the lifting of the device, so that the resistance between the two during the lifting is the friction when the resistance plate contacts the surface of the pole, which facilitates the lifting of the device, and when the vertical plate and the inclined block are pulled, they will squeeze the resistance spring to drive the vertical plate to pull the pull rope in the opposite direction, thereby reducing the gap between the pull rope and the L-shaped rod, making the connection between the two tighter, thereby increasing the stability of the device when in use.

[0018] 3. The present application provides a through hole for the driving rod to pass through on the rotating plate located on the lower half hoop plate. When connecting, the driving rod is clamped by a telescopic clamp rod and passed through the through hole to be inserted into the installation sleeve, so as to connect the rotating plate on the lower half hoop plate with the rotating plate on the upper half hoop plate. When the driving rod is rotated, the inner wall of the upper limiting groove drives the side wall of the limiting block to be driven, so that when the driving rod rotates, it can simultaneously drive the rotating plate on the lower half hoop plate and the rotating plate on the upper half hoop plate to rotate at the same time. During installation, the upper hoop plate and the lower hoop plate are installed and connected at the same time, which saves installation time, reduces the time for the operator to support the device, and increases the practicality and safety of the device.

[0019] 4. In the present application, since the device is installed and there is no need for the driving rod to rotate, the driving rod is pulled out of the installation sleeve and then inserted into the accommodating sleeve. At this time, the driving rod body blocks the inner wall of the accommodating sleeve, so that the rotation of the rotating plate is restricted, thereby reducing the possibility of the rotating plate accidentally sliding when the device is in use, and further increasing the safety of the device.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0022] like Figure 1 - Fig.12 As shown, a portable line insulation protection umbrella proposed in the first embodiment of the present application includes: The upper hoop plate 1 comprises two upper half hoop plates 101, both of which are semi-circular and form a complete annular plate body when the two are spliced ​​together, and are used to be fixed on the electric pole; The upper hoop plate 101 is provided with an arc groove 102, in which a sliding plate 103 is slidably installed, and teeth 104 are installed on the sliding plate 103. A rotating plate 105 is rotatably installed on one of the upper hoop plates 101, and a protruding tooth 106 meshing with the teeth 104 is installed on the rotating plate 105. The sliding plate 103 is arc-shaped. When in use, the center of the arc groove 102, the center of the sliding plate 103 and the center of the upper hoop plate 101 are at the same point. , by rotating the rotating plate 105, the teeth 104 drive the sliding plate 103 to slide in the arc groove 102, so that the sliding plate 103 on one side of the upper half hoop plate 101 slides into the arc groove 102 on the other side of the upper half hoop plate 101, and the sliding plate 103 on the other side of the upper half hoop plate 101 is pressed and pushed into the arc groove 102 on the upper half hoop plate 101 on this side by means of resistance, so that the two upper half hoop plates 101 are preliminarily connected; A groove 107 is provided on the sliding plate 103, and a protrusion 108 is slidably installed on the upper hoop plate 101 through a connecting spring 109. The protrusion 108 is used to be inserted into the groove 107 on the adjacent sliding plate 103. The protrusion 108 is provided with arc surfaces on both sides of the sliding direction of the sliding plate 103. When the sliding plate 103 slides into the arc groove 102 on the opposite side, the side wall of the sliding plate 103 resists the protrusion 108, so that the connecting spring 109 is compressed. When the sliding plate 103 moves to align with the groove 107, the connecting spring 109 pushes the protrusion 108 to be inserted into the groove 107, thereby connecting the two upper hoop plates 101 and limiting the tendency of the two to move away from each other. The lower hoop plate 2 comprises two lower half hoop plates 201. The structure on the lower half hoop plate 201 is consistent with the structure on the upper half hoop plate 101. The lower half hoop plate 201 and the upper half hoop plate 101 are hinged with umbrella ribs 3. The free ends of the umbrella ribs 3 are installed with umbrella canopies 5. When the lower hoop plate 2 is close to the upper hoop plate 1, the free ends of the umbrella ribs 3 drive the umbrella canopy 5 away from the lower hoop plate 2 and the upper hoop plate 1. The lower half hoop plate 201 also has structures such as arc grooves 102, sliding plates 103, teeth 104, rotating plates 105, protruding teeth 106, grooves 107 and protrusions 108. When connecting, the connection method of the lower hoop plate 2 is consistent with that of the upper hoop plate 1. The sliding plate 103 is moved from one lower half hoop plate 201 to another lower half hoop plate 201 by rotating the rotating plate 105. The ribs 3 are consistent with the skeleton structure of the existing umbrellas, and there are two umbrella covers 5. When the upper hoop plate 1 and the lower hoop plate 2 are connected, the two umbrella covers 5 form a complete umbrella cover 5. When the device is used, the lower hoop plate 2 is pushed upward to make it close to the upper hoop plate 1, so that the ribs 3 rotate, and then the umbrella cover 5 is unfolded to protect the user. The fixing member 4 includes a mounting plate 401 mounted on the upper hoop plate 101 or the lower hoop plate 201. The mounting plate 401 on the upper hoop plate 101 is located on its upper surface, and the mounting plate 401 on the lower hoop plate 201 is installed on its lower surface, which reduces the possibility of the mounting plate 401 blocking the upper hoop plate 1 and the lower hoop plate 2 when they are close to each other, thereby increasing the feasibility of the device; The mounting plate 401 is hinged with a contact plate 402, the lower surface of the contact plate 402 is hinged with the upper surface of the mounting plate 401, and when the contact plate 402 rotates, the upper surface of the contact plate 402 approaches or moves away from the inner cavity of the upper hoop plate 1, so that when the device is installed, the contact plate 402 can contact the electric pole; A vertical plate 403 is slidably mounted on the mounting plate 401, and an inclined block 406 for resisting the contact plate 402 is mounted on the vertical plate 403. The inclined block 406 has an inclined surface, so that the length of the inclined block 406 gradually decreases from the side away from the mounting plate 401 to the side close to the mounting plate 401, so that when the inclined block 406 slides toward the mounting plate 401, it gradually resists the contact plate 402, and then rotates toward the inner cavity of the upper hoop plate 1 or the inner cavity of the lower hoop plate 2, and then resists the electric pole; A pull rope 404 is installed on the contact plate 402, and the free end of the pull rope 404 is connected to the upper hoop plate 101 or the lower hoop plate 201. An L-shaped rod 405 is installed on the sliding plate 103. When the sliding plate 103 slides, the L-shaped rod 405 pulls the pull rope 404, forcing the inclined block 406 to contact the contact plate 402, so that the contact plate 402 contacts the electric pole. When the upper hoop plate 101 or the lower hoop plate 201 is installed, the sliding plate 103 slides, driving the L-shaped rod 405 to pull the pull rope 404, so that the vertical plate 403 is pulled, and the inclined block 406 is driven to slide in the direction close to the installation plate 401, so that the inclined block 406 contacts the contact plate 402, thereby forcing the contact plate 402 to contact the electric pole, thereby increasing the stability of the device during installation; The mounting angle of the mounting plate 401 is perpendicular to the sliding direction of the sliding plate 103, so that when the contact plate 402 contacts the electric pole, the electric pole applies a force in the opposite direction to the contact plate 402, so that the upper hoop plate 101 or the lower hoop plate 201 slides away from the sliding plate 103, thereby causing the inner wall of the groove 107 to contact the protrusion 108, thereby reducing the gap between the groove 107 and the protrusion 108, further increasing the stability of the sliding plate 103 during use, and increasing the stability of the device during installation; When installing the device, two operators are required to operate. Since the device of the present application does not need to be installed by bolts, the operator can first support and push the upper hoop plate 1 and the lower hoop plate 2 to the height of the electric pole through the telescopic clamp rod. At this time, the operator on the side away from the rotating plate 105 supports the device, and the operator on the rotating plate 105 side rotates the rotating plate 105 through the telescopic clamp rod to complete the installation. When in use, there is no need to carry the device to climb, and the installation can be carried out on the ground, which is safer. Compared with the prior art, after aligning the two upper half hoop plates 101 during use, the rotating plate 105 is rotated so that the protruding teeth 106 thereon drive the sliding plate 103 to slide through the teeth 104, so that the sliding plates 103 located on the two upper half hoop plates 101 are respectively inserted into the arc grooves 102 on the opposite sides, and the protruding blocks 108 are inserted into the grooves 107 to limit the sliding of the sliding plates 103. The lower hoop plate 2 is also operated in the same way, so that the upper hoop plate 1 and the lower hoop plate 2 are formed. During the process, the pull rope 404 pulls the inclined block 406 to contact the contact plate 402 through the pulling of the L-shaped rod 405, so that the two can contact the electric pole, thereby increasing the installation strength of the device. When connecting the device, the lower hoop plate 2 is moved closer to the upper hoop plate 1 to open the umbrella cover 5. When in use, the device can be installed in advance through the telescopic clamping rod carried during construction, thereby increasing the safety of the device when in use. Embodiment 2

[0023] like Figure 3 and Figure 4 As shown, the second embodiment is based on the first embodiment and further discloses the fixing member 4, the rib 3, the upper hoop plate 101 and the lower hoop plate 201. In the second embodiment, the upper hoop plate 101 and the lower hoop plate 201 are provided with an arc groove 407, and a hard block 408 is installed on the free end of the pull rope 404. The hard block 408 and the arc groove 407 are slidably matched. When in use, the free end of the pull rope 404 can slide in a direction away from the mounting plate 401, so that when the pull rope 404 is resisted by the L-shaped rod 405, it does not pull the vertical plate 403 by deforming itself, but pulls it by displacement, thereby increasing the service life of the pull rope 404. In this embodiment, the pull rope 404 can be made of a material with poor deformation performance but solid and wear-resistant, such as a hemp rope or an iron chain, thereby increasing the safety of the device when in use; When sliding, the block 408 contacts the inner wall of the arc groove 407 for guidance, so that the pull rope 404 can be more stable when being pulled; A resistance spring 409 is installed between the vertical plate 403 and the mounting plate 401. The resistance spring 409 forces the inclined block 406 to move away from the mounting plate 401, so that when the device is lifted, the resistance plate 402 will not resist the electric pole, so that the resistance between the two during lifting is the friction when the resistance plate 402 contacts the surface of the electric pole and the gravity of the device itself, which facilitates the lifting of the device. When the vertical plate 403 and the inclined block 406 are pulled, they will squeeze the resistance spring 409 to drive the vertical plate 403 to pull the pull rope 404 in the opposite direction, thereby reducing the gap between the pull rope 404 and the L-shaped rod 405, making the connection between the two tighter, thereby increasing the stability of the device when in use.

[0024] like Figure 3 and Fig. 9As shown, in the second embodiment, a mounting sleeve 6 is installed on the rotating plate 105 located on the upper half hoop plate 101, and a driving rod 7 penetrating the rotating plate 105 is movably inserted on the rotating plate 105 located on the lower half hoop plate 201, and the driving rod 7 is used to be inserted in the mounting sleeve 6, and a limiting groove 8 is opened on the driving rod 7, and a limiting block 9 slidingly matched with the limiting groove 8 is installed in the mounting sleeve 6. When in use, since the umbrella ribs 3 are used to install the umbrella surface 5, in order to make the umbrella surface 5 on the same side more complete, it is necessary to make the upper half hoop plate 101 and the lower half hoop plate 201 on the same side be uniformly connected by the umbrella ribs 3, so that when lifting, the two are lifted at the same time, that is, the whole device is divided into two parts, each part includes an upper half hoop plate 101 and a lower half hoop plate 201; A through hole for the driving rod 7 to pass through is provided on the rotating plate 105 located on the lower half hoop plate 201. When connecting, the driving rod 7 is clamped by the telescopic clamping rod and inserted into the installation sleeve 6 through the through hole, so that the rotating plate 105 located on the lower half hoop plate 201 is connected with the rotating plate 105 located on the upper half hoop plate 101. When the driving rod 7 is rotated, the inner wall of the upper limiting groove 8 drives the side wall of the limiting block 9 to be driven, so that when the driving rod 7 rotates, it can simultaneously drive the rotating plate 105 located on the lower half hoop plate 201 and the rotating plate 105 located on the upper half hoop plate 101 to rotate. During installation, the upper hoop plate 1 and the lower hoop plate 2 are installed and connected at the same time, which saves installation time, reduces the time for the operator to support the device, and increases the practicality and safety of the device.

[0025] like Figure 5 As shown, in the second embodiment, the umbrella rib 3 includes an upper main rod 301, a lower main rod 302, a connecting rod 303 and a mounting rod 304. The upper main rod 301 is hinged on the upper half hoop plate 101, and the lower main rod 302 is hinged on the lower half hoop plate 201. The free end of the upper main rod 301 is hinged to the rod body of the lower main rod 302. One end of the connecting rod 303 is hinged to the rod body of the upper main rod 301, and the other end is hinged to the rod body of the mounting rod 304. One end of the mounting rod 304 is hinged to the lower main rod 301. The free end of the upper main rod 301 is hinged, and the mounting rod 304 is used to connect with the umbrella cover 5. The connection mode among the upper main rod 301, the lower main rod 302, the connecting rod 303 and the mounting rod 304 is consistent with the connection mode of the frame of the umbrella. When in use, the lower main rod 302 moves in the direction of the upper main rod 301 to make the two rotate, thereby driving the mounting rod 304 to extend in the direction away from the electric pole, thereby opening the umbrella cover 5, just like opening an umbrella, to protect the operator; The accommodating sleeve 10 is installed on the rotating plate 105, and the accommodating sleeve 10 is also installed on the upper main rod 301 and the lower main rod 302 near the rotating plate 105. When the driving rod 7 is inserted into the accommodating sleeve 10, the rotation of the rotating plate 105 is restricted. When in use, the accommodating sleeve 10 located on the upper main rod 301 and the lower main rod 302 is connected to the hinge rod at the hinge point of the two, so that even if the upper main rod 301 or the lower main rod 302 rotates, the opening direction of the accommodating sleeve 10 will not change. When the device is fixed, the opening of the accommodating sleeve 10 on the rotating plate 105 is connected to the opening of the accommodating sleeve 10 located on the upper main rod The openings on the accommodating sleeve 10 on the upper main rod 301 and the lower main rod 302 are aligned. At this time, since the device has been installed, there is no need to rotate the driving rod 7. At this time, the driving rod 7 is pulled out of the installation sleeve 6 and then inserted into the accommodating sleeve 10. At this time, the position of the accommodating sleeve 10 on the upper main rod 301 and the lower main rod 302 is fixed, and the inner wall of the accommodating sleeve 10 on the rotating plate 105 is blocked by the rod body of the driving rod 7, so that the rotation of the rotating plate 105 is restricted, reducing the possibility of the rotating plate 105 sliding accidentally when the device is in use, thereby further increasing the safety of the device. Embodiment 3

[0026] like Figure 1 and Fig.12 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a sleeve rod 11 is rotatably mounted on the lower half hoop plate 201, and an insertion rod 13 is slidably mounted in the sleeve rod 11 through an extrusion spring 12. A collar 14 is mounted on the driving rod 7, and the insertion rod 13 is used to be inserted in the collar 14. Before the driving rod 7 is inserted into the accommodating sleeve 10, the sleeve rod 11 is rotated to drive the insertion rod 13 to rotate in a direction away from the accommodating sleeve 10. After the driving rod 7 is inserted into the accommodating sleeve 10, the sleeve rod 11 is rotated to move toward the collar 14. The rod 13 is rotated so that the insertion rod 13 contacts the side wall of the collar 14, forcing the extrusion spring 12 to be compressed, thereby causing the insertion rod 13 to slide into the sleeve rod 11. When the sleeve rod 11 is rotated to be aligned with the collar 14, the interference between the insertion rod 13 and the side wall of the collar 14 is released, and the extrusion spring 12 pushes the sleeve rod 11 to be inserted into the collar 14. The insertion rod 13 contacts the inner wall of the collar 14, restricting the sliding of the driving rod 7 in the accommodating sleeve 10, thereby increasing the stability of the driving rod 7 when in use, and further increasing the safety of the device when in use. After the maintenance is completed, the sleeve rod 11 is pressed to separate it from the sleeve ring 14. When the operator reaches the ground, the driving rod 7 is also brought down, and it is inserted into the installation sleeve 6 again through the telescopic clamp rod, and the rotating plate 105 is rotated in the opposite direction, so that the connection between the upper half hoop plate 101 and the lower half hoop plate 201 is released, which is also convenient for disassembly of the device, further increasing the practicality of the device.

[0027] In the third embodiment, the upper hoop plate 101 and the lower hoop plate 201 are hinged with a shielding plate 15, and the upper main rod 301 and the lower main rod 302 are both installed with a pushing rod 16. When the lower hoop plate 2 is close to the upper hoop plate 1, the upper main rod 301 and the lower main rod 302 drive the pushing rod 16 to resist the shielding plate 15, so that the projection of the shielding plate 15 on the upper hoop plate 101 or the lower hoop plate 201 blocks the sliding plate 103, wherein the pushing rod 16 located on the upper main rod 301 and the lower main rod 302 have different shapes but the same function, and are both used to push the shielding plate 15; Under normal circumstances, the shielding plate 15 is affected by gravity and is in a drooping state. The side of the shielding plate 15 located at the hinge point close to the push rod 16 is longer than the opposite side, so that the center of gravity is close to the push rod 16. When it is drooping, it is also close to the side of the push rod 16. When the lower hoop plate 2 approaches the upper hoop plate 1, the upper main rod 301 and the lower main rod 302 both rotate upward, so that the push rod 16 pushes the shielding plate 15, and then the shielding plate 15 blocks the sliding plate 103, reducing the possibility of debris falling between the teeth 104 and causing the sliding of the sliding plate 103 to get stuck when the operator disassembles and assembles the wires, so that the device can be disassembled smoothly after maintenance is completed.

[0028] In the third embodiment, the upper hoop plate 101 and the lower hoop plate 201 are provided with an oil tank 17, the oil tank 17 has an opening, the arc groove 102 is provided with an oil inlet hole 18 connected with the opening of the oil tank 17, and a stopper 20 for covering the opening of the oil tank 17 is slidably installed on the oil tank 17 through a return spring 19, one end of the stopper 20 passes through the oil tank 17 and is located on its upper surface, and an expansion panel 21 for contacting with the protruding teeth 106 is installed on the stopper 20, and the oil tank 17 is installed near the rotating plate 105, and the height of the upper surface of the expansion panel 21 is higher than the protruding teeth 106. The lowest point of the tooth 106 makes it possible for the protruding tooth 106 to not only push the tooth 104 but also press the expansion panel 21 when the rotating plate 105 rotates, so that the expansion panel 21 slides downward, driving the stopper 20 to release the obstruction of the oil tank 17 opening, so that the lubricating oil inside the stopper can enter the arc groove 102 to lubricate the sliding plate 103, so that the sliding plate 103 can slide more smoothly when in use, which is convenient for the operator to drive the sliding plate 103 when rotating the rotating plate 105 on the ground, thereby increasing the practicality of the device; When the protruding tooth 106 is released from the conflict with the expansion panel 21, the reset spring 19 resets and drives the block 20 to cover the opening of the oil tank 17, so that the lubricating oil is discharged intermittently, saving the lubricating oil. A channel is opened on the oil tank 17 for adding lubricating oil therein, and a bolt is threadedly connected in the channel. The channel is sealed by the bolt, which reduces the possibility of leakage of the lubricating oil and increases the practicability of the device.

[0029] In the third embodiment, a guide block 22 is installed in the oil tank 17, and a slope is provided on the guide block 22 toward the opening of the oil tank 17. When in use, the lubricating oil in the oil tank 17 can gather toward the opening of the oil tank 17 through the slope of the guide block 22, so as to facilitate better discharge of the lubricating oil.

[0030] In the third embodiment, a stop plate 23 is installed in the arc groove 102. When the sliding plate 103 slides to contact the stop plate 23, the sliding plate 103 is at the maximum sliding range. When in use, when the sliding plate 103 is inserted into the arc groove 102 on the opposite side, it gradually approaches the stop plate 23 until it is blocked by the stop plate 23, thereby preventing the sliding plate 103 from sliding further to the opposite side. The sliding plate 103 can cooperate with the protrusion 108 to limit the sliding of the sliding plate 103, so that the sliding plate 103 will not be inserted too deeply into the arc groove 102 on the opposite side, so that the teeth 104 on the sliding plate 103 can always be meshed with the protrusions 106, thereby increasing the feasibility of the device. During the process, the stop plate 23 is fixedly arranged in the arc groove 102, so that when the sliding plate 103 moves to contact with it, it will definitely stop, and will not continue to contact the protrusion 108, so that it is separated from the groove 107, thereby increasing the practicality of the device; A block with half its circumference is installed on the sliding plate 103, which is slidably connected to the arc groove 102 through the block. The block is installed on the sliding plate 103 and needs to be inserted into one end of the arc groove 102 on the other side. There is a gap between the side of the sliding plate 103 where the block is not installed and the arc groove 102, and the stop plate 23 is installed on this side, so that the stop plate 23 has an installation position in the arc groove 102, thereby improving the feasibility of the device.

[0031] In the third embodiment, an arcuate surface is provided at the end of the insertion rod 13, and the insertion rod 13 contacts the side wall of the ring 14 through the arcuate surface. When the insertion rod 13 contacts the side wall of the ring 14, the arcuate surface guides the insertion rod 13 to slide into the sleeve rod 11, thereby increasing the feasibility of connecting the insertion rod 13 and the ring 14.
