Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings, in particular to an electric power fitting with a double wire clamping type. Background Technique

[0002] Electric power fittings are metal accessories that connect and combine various devices in the power system and play the roles of transmitting mechanical loads, electrical loads, and certain protective functions. Among them, protective fittings are usually used to protect wires. Due to the large span and high poles of high-voltage overhead lines, when the wires are blown by strong winds, they will vibrate strongly. Long-term periodic vibration will cause fatigue damage to the wires.

[0003] The prior art discloses an electric power fitting with a double wire clamping type with the publication number of: CN213602382U, which includes a fixed seat, a second fixed strip, a second fixed plate, a first nut, and a groove. A fixed block is placed on the fixed seat. A first bolt penetrates through the fixed block, and a first fixed plate is fixed on the fixed block. A first fixed strip is fixed on the first fixed plate. A second bolt penetrates through the first fixed strip. A connecting rod penetrates through the fixed seat, and a hammer head is fixed on the connecting rod. A second nut is installed on the second bolt, and a second fixed plate is fixed on the fixed seat. This electric power fitting with a double wire clamping type is provided with left and right groups of fixed strips. Through the interaction between the first fixed strip and the second fixed strip, a good fixing effect can be provided for the fixed plate. At the same time, the mutual fitting of the fixed seat and the fixed block in the middle of the fixed strip will further increase the acting force between the fixed plates, realizing the double clamping of the wire.

[0004] The above-mentioned electric power fitting acts on the wire indirectly through the first fixed plate and the second fixed plate. The contact areas of the first fixed plate and the second fixed plate with the wire are large, which can reduce the pressure on the wire without affecting the fastening property and improve the service life of the wire. However, when the above-mentioned electric power fitting is clamped, only two clamp seats are simply set to approach each other and then cooperate with bolts for clamping. When clamping, it can only be adapted to clamp wires of one model. Once there are gaps inside, it will affect the clamping strength and the adaptability is low, and the effect during use is not good, so it needs to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an electric power fitting with a double wire clamping type to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An electric power fitting with a double wire clamping type includes a fixed seat, a clamping device is arranged inside the fixed seat, and a limiting device is arranged on the top of the clamping device.

[0007] The clamping device includes a first half-ring member, a side-end connection block, a hydraulic telescopic rod, a fixed half-ring member, a top elastic half-ring member, an inner spring, a groove, a telescopic rod, and a suction cup. The first half-ring member is fixedly connected to the right side of the fixed seat. The hydraulic telescopic rod is fixedly connected to the top of the side-end connection block. The fixed half-ring member is fixedly connected to the left side of the hydraulic telescopic rod. The fixed half-ring member is slidably connected to the bottom of the supporting plate. The top elastic half-ring member is fixedly connected to the inner ring of the first half-ring member.

[0008] Preferably, the limiting device includes a connecting ring member, a threaded rod member, a limiting kit, and a supporting plate. The connecting ring member is fixedly connected to the top of the fixed seat. The threaded rod member is threadedly connected to the inside of the fixed seat. The limiting kit is fixedly connected to the top of the supporting plate.

[0009] Preferably, the supporting plate is fixedly connected to the top of the fixed half-ring member. The threaded rod member is threadedly connected to the inside of the supporting plate.

[0010] Preferably, an internal threaded groove is formed in the connecting ring member. The threaded rod member is threadedly connected to the inside of the connecting ring member. Rotate the threaded rod member downward until it contacts the center of the top of the cable for extrusion and fixation. The setting of the connecting ring member and the internal threaded groove ensures that the threaded rod member can be rotated downward to ensure the normal use of the device.

[0011] Preferably, the groove is formed in the center of the bottom of the top elastic half-ring member. The suction cup is fixedly connected to the bottom of the telescopic rod. The setting of the groove can change the radian of the top elastic half-ring member, thereby adjusting the contact area during clamping and achieving the purpose of anti-slip.

[0013] Preferably, a rectangular placement plate member is fixedly connected to the bottom right side of the first half-ring member. The side-end connection block is fixedly connected to the top of the rectangular placement plate member.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. For this electric power fitting with a double wire clamping type, by providing a clamping device, the suction cup can be buckled into the groove. Then, the hydraulic telescopic rod can be activated on the right side to drive the fixed half-ring member to move to the right. The inner spring generates a reverse elastic force to cooperate with the extrusion force of the hydraulic telescopic rod and the fixed half-ring member to clamp the cable. Moreover, the clamping component adopted is not simply two docking ring members, with high adaptability and a reduced probability of gaps inside, which can ensure the clamping strength.

[0016] 2.

The first half-ring member 301 is fixedly connected to the right side of the fixed seat 1. The hydraulic telescopic rod 303 is fixedly connected to the top of the side-end connecting block 302. The fixed half-ring member 304 is fixedly connected to the left side of the hydraulic telescopic rod 303. The fixed half-ring member 304 is slidably connected to the bottom of the supporting plate 204. The top elastic half-ring member 305 is fixedly connected to the inner circle of the first half-ring member 301. A rectangular placement plate member is fixedly connected to the bottom right side of the first half-ring member 301. The side-end connecting block 302 is fixedly connected to the top of the rectangular placement plate member. The groove 307 is opened at the center of the bottom of the top elastic half-ring member 305. The suction cup 309 is fixedly connected to the bottom of the telescopic rod 308. The setting of the groove 307 can change the radian of the top elastic half-ring member 305, thereby adjusting the contact area during clamping and achieving the purpose of anti-slip. The inner spring 306 is fixedly connected to the inside of the first half-ring member 301. The telescopic rod 308 is fixedly connected to the inside of the top elastic half-ring member 305.

[0026] The limiting device 2 includes a connecting ring member 201, a threaded rod member 202, a limiting sleeve 203, and a supporting plate 204. The connecting ring member 201 is fixedly connected to the top of the fixed seat 1. The threaded rod member 202 is threadedly connected to the inside of the fixed seat 1.
