[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-8A quick-release wire clamp for electric power fittings provided by an embodiment of the present invention comprises a mounting frame 1, a wire clamp assembly 2, a positioning locking member 3 and a sliding portion 4, wherein the mounting frame 1 is fixedly connected to the electric power fitting, the wire clamp assembly 2 comprises a first wire clamp 201 slidably connected to the mounting frame 1 in a transverse direction, a second wire clamp 202 slidably connected to the first wire clamp 201 in a vertical direction, and a one-way locking member 203 for preventing the second wire clamp 202 from sliding and separating relative to the first wire clamp 201; the positioning locking member 3 is configured to lock the first wire clamp 201 on the mounting frame 1 and unlock it; the sliding portion 4 is slidably connected to the mounting frame 1 in a transverse direction, and the sliding portion 4 has the following processes in sequence during the sliding relative to the mounting frame 1: a first stroke, the sliding portion 4 drives the second wire clamp 202 to slide close to the first wire clamp 201 through the transmission assembly 5 to clamp the cable, and the sliding portion 4 triggers the positioning locking member 3 to unlock; a second stroke, the sliding portion 4 drives the first wire clamp 201 and the second wire clamp 202 to slide relative to the mounting frame 1 in a transverse direction through the transmission assembly 5 to tighten the cable. Specifically, when the sliding part 4 is in the sliding stroke, the transmission assembly 5 can be used to drive the second wire clamp 202 to move downward relative to the first wire clamp 201 so that the first wire clamp 201 and the second wire clamp 202 can achieve the effect of clamping the cable. At the same time, the one-way locking piece 203 can be used to prevent the second wire clamp 202 from separating from the first wire clamp 201, thereby further achieving the effect of clamping the cable, which is convenient for the cable and the power fitting to be fixedly connected through the wire clamp assembly 2; after the first wire clamp 201 and the second wire clamp 202 clamp the cable, the sliding part 4 continues to slide horizontally during the stroke, and the sliding part 4 will trigger the positioning locking piece 3 to unlock, and then with the cooperation of the transmission assembly 5, the entire wire clamp assembly 2 can be driven to slide horizontally on the mounting frame 1, thereby achieving the effect of tightening the cable. The whole process is simple to operate and can reduce the risk of workers working at heights.

[0027] Among them, the transmission assembly 5 includes: a screw rod 501, which is threadedly connected to the threaded hole on the mounting frame 1, and the end of the screw rod 501 is rotatably connected to the sliding part 4; a slider 502; which is laterally slidably connected to the mounting frame 1, and the slider 502 is provided with a through hole for the screw rod 501 to pass through; at least one connecting rod 504, one end of which is rotatably connected to the slider 502, and the other end is rotatably connected to the second wire clamp 202; a compression spring 503, which is movably sleeved on the screw rod 501, one end of the compression spring 503 is abutted against the sliding part 4, and the other end is abutted against the sliding part. The slider 502 is fixedly connected with an extension rod 11 corresponding to each connecting rod 504. One end of the connecting rod 504 away from the second wire clamp 202 is rotatably connected to the corresponding extension rod 11. The mounting frame 1 is provided with a limit slot 7 for the extension rod 11 to slide. The limit rod 8 is slidably connected in the limit slot 7. One end of the limit rod 8 is fixedly connected to the sliding part 4. Specifically, the limit slot 7 is provided to allow the extension rod 11 to extend out of the mounting frame 1, so as to be rotatably connected to the connecting rod 504. At the same time, the limit rod 8 fixedly connected to the sliding part 4 can also slide in the limit slot 7, which not only plays a guiding role, but also prevents the sliding part 4 from rotating during the rotation of the screw 501. It should be noted that the direction in which the slider 502 and the sliding part 4 slide horizontally is the length direction of the screw 501. Among them, a clamp is fixedly connected to the end of the screw 501 away from the second wire clamp 202, and a clamp is provided on the clamp. The staff can use tools to insert into the clamp into the clamp, which is convenient for the staff to rotate the screw 501. When using some longer tools, the force arm can be increased, thereby achieving a labor-saving effect.

[0028] Specifically, during the rotation of the screw rod 501, the sliding part 4 will be driven to slide laterally, and with the cooperation of the compression spring 503 with sufficiently large elastic force, the slider 502 will be driven to slide linearly synchronously, and the sliding slider 502, with the cooperation of the connecting rod 504, can drive the second wire clamp 202 to move downward relative to the first wire clamp 201 to clamp the cable, and at the end of the first stroke, the sliding part 4 can trigger the positioning locking part 3 to unlock, and then the screw rod 501 continues to rotate. At this time, the first wire clamp 201 and the second wire clamp 202 can move laterally with the slider 502, thereby playing a role in tightening the cable in the moving direction of the slider 502, thereby preventing the entire cable from hanging after the cable is fixedly connected to the power fitting through the wire clamp assembly 2, and can avoid the cable from swinging significantly when fishing in a windy state, causing looseness between the cable and the power fitting.

[0029] Among them, the one-way locking member 203 includes a wedge-shaped tooth row 2031, a first locking head 2033 and a first elastic member 2032. The wedge-shaped tooth row 2031 is fixedly arranged on the first wire clamp 201, and the wedge-shaped surface of each locking tooth of the wedge-shaped tooth row 2031 faces upward; the first locking head 2033 is slidably connected to the second wire clamp 202; the elastic force of the first elastic member 2032 causes the first locking head 2033 to abut against the wedge-shaped tooth row 2031. It should be noted that each of the teeth of the wedge-shaped tooth row 2031 includes a wedge-shaped surface and a horizontal surface, and the horizontal surface faces downward, and a tooth groove is formed between the teeth of two adjacent wedge-shaped tooth rows 2031, and the first lock head 2033 is a wedge-shaped block, the wedge surface of the first lock head 2033 faces downward, and the horizontal surface faces upward. When the one-way locking member 203 is in the locked state, the first lock head 2033 will be stuck in the tooth groove; it should also be noted that the first elastic member 2032 includes a first spring and a guide rod, the guide rod is slidably connected to the second wire clamp 202, the first spring is sleeved on the guide rod, and the first spring One end is in contact with the first lock head 2033, and the other end is in contact with the second wire clamp 202, and the first spring can drive the first lock head 2033 to be inserted into the tooth groove of the wedge-shaped tooth row 2031 during the process of restoring the deformation; it should be further explained that the guide rod is away from the first lock head 2033 and is fixedly connected to one end of the second wire clamp 202 through the second wire clamp 202, and when it is necessary to unlock the clamping between the first wire clamp 201 and the second wire clamp 202, the staff can pull the pull rod to make the first lock head 2033 in the locked state disengage from the tooth groove of the wedge-shaped tooth row 2031, thereby achieving the unlocking effect.

[0030] Specifically, in the first stroke, the first locking head 2033 will descend along with the second wire clamp 202, and driven by the first elastic member 2032, the first locking head 2033 can be engaged with the tooth grooves of the wedge-shaped tooth row 2031 one by one from top to bottom until the first wire clamp 201 and the second wire clamp 202 completely clamp the cable; wherein, when the first locking head 2033 is engaged with the tooth grooves of the wedge-shaped tooth row 2031, because the horizontal surfaces of the teeth of the wedge-shaped tooth row 2031 abut against the horizontal surface of the first locking head 2033, the second wire clamp 202 can be prevented from vertically moving away from the first wire clamp 201, thereby preventing the clamped cable from loosening.

[0031] The positioning locking member 3 includes a sliding member 301, a receiving chamber 304 and a second elastic member 305. The sliding member 301 has a second locking head 302 and a first arc block 303. The receiving chamber 304 is provided on the mounting frame 1. The sliding member 301 is vertically slidably connected in the receiving chamber 304. During the process of the second elastic member 305 restoring its elasticity, the second wire clamp 202 has a locking position abutted by the second locking head 302. The sliding portion 4 is fixedly connected with a second arc block 6. At the end of the first stroke, the second locking head 302 is driven to slide vertically into the receiving chamber 304 through the abutment of the second arc block 6 with the first arc block 303 to disengage the second wire clamp 202 from the locking position. The second elastic member 305 is a spring telescopic rod, one end of which is fixedly connected to the bottom end of the receiving chamber 304, and the other end is fixedly connected to the sliding member 301. Specifically, at the end of the first sliding stroke of the sliding portion 4, in its preferred state, when the first wire clamp 201 and the second wire clamp 202 are closed to clamp the cable, the second arc block 6 fixedly connected to the sliding portion 4 abuts against the first arc block 303 to force the second locking head 302 of the sliding member 301 to be completely immersed in the storage cavity 304 to make the second wire clamp 202 disengage from the locking position, thereby unlocking the second wire clamp 202; in other states, after the first wire clamp 201 and the second wire clamp 202 are closed to clamp the cable, the second wire clamp 202 is still in the locking position locked by the second locking head 302 on the sliding member 301, and the slider Because 502 is in a locked state with the cooperation of the one-way locking member 203, the connecting rod 504 and the extension rod 11, when the screw 501 continues to be rotated, the sliding part 4 will compress the compression spring 503 to make the sliding part 4 close to the slider 502. In the process of the sliding part 4 sliding close to the slider 502, the sliding part 4 can force the second locking head 302 of the sliding member 301 to be completely immersed in the storage cavity 304 through the abutment cooperation with the first arc block 303 through the second arc block 6 to make the second wire clamp 202 disengage from the locking position, so that the sliding part 4 and the slider 502 can drive the wire clamp assembly 2 to slide horizontally under the drive of the screw 501 to tighten the cable.

[0032] As another embodiment provided by the present invention, specifically as follows Figure 8 As shown, the first wire clamp 201 is provided with a first wire groove 9, and the second wire clamp 202 is provided with a second wire groove 10. When the second wire clamp 202 vertically slides and closes relative to the first wire clamp 201, the first wire groove 9 and the second wire groove 10 form a clamping cavity for clamping the cable, and the length direction of the clamping cavity is a curved path. Specifically, when the second wire clamp 202 is close to the first wire clamp 201, the clamping cavity formed by the first wire groove 9 and the second wire groove 10 can clamp the cable, and increase the contact area between the cable and the first wire groove 9 and the second wire groove 10, thereby increasing friction, achieving a better clamping effect, and facilitating the subsequent tightening of the cable.

[0033] 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.
