Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a wrench for installing a large-section conductor spacer includes a base plate 400, two positioning rods 500, a screw 300, and a sleeve 200. The sleeve 200 is perpendicular to the bottom plate 400, one end of the sleeve 200 is perpendicular to the bottom plate 400, and the other end is provided with a threaded hole 210 along the length direction. The screw 300 is in threaded connection with the threaded hole 210, so that the sleeve 200 is sleeved outside the screw 300. Two locating levers 500 set up in sleeve 200 both sides in parallel, and two locating levers 500 all set up with bottom plate 400 face is perpendicular, and two locating levers 500 rotate with bottom plate 400 through the bearing and are connected to make two locating levers 500 can rotate around sleeve 200 week side.

Set up on the screw rod 300 along its length direction's bar hole 310, be provided with baffle 311 in the bar hole 310, and baffle 311 rotates with bar hole 310 lateral wall and is connected to make the both ends of baffle 311 rotate to the direction that is close to or keeps away from bottom plate 400 respectively, and with the butt of locating lever 500 lateral wall.

The bottom plate 400 is provided with a limiting groove 410 at one side away from the screw 300. The wrench further comprises a handle 100, wherein one end of the handle 100 is located in the limiting groove 410 and is rotatably connected with the side wall of the limiting groove 410, so that the free end of the handle 100 rotates towards the direction close to or far away from the screw 300. When the handle 100 rotates to the side close to the screw 300 and is attached to the bottom of the limiting groove 410, the two sides of the handle 100 are attached to the two side walls of the limiting groove 410, so that the stress of the connecting position of the handle 100 and the bottom plate 400 is reduced when a worker rotates the handle 100.

The gravity center of the baffle 311 is shifted towards one end of the baffle 311, so that the baffle 311 rotates under the action of self gravity until the two ends of the baffle 311 are both positioned in the strip-shaped holes 310. The end of the baffle 311 away from the center of gravity is provided with an inclined plane. The screw 300 is provided with a positioning hole 320 for communicating the threaded hole 210 and the strip-shaped hole 310. The screw 300 is provided with an adjusting assembly 600 for adjusting the rotation of the baffle 311. The adjustment assembly 600 includes an adjustment lever 610 and an adjustment spring 620. The adjusting rod 610 is connected with the positioning hole 320, the strip-shaped hole 310 and the threaded hole 210 in a sliding manner along the length direction of the positioning hole 320, and an inclined surface attached to the baffle 311 is formed at one end of the adjusting rod 610, which is far away from the bottom plate 400. The adjusting spring 620 is sleeved outside the adjusting rod 610, and one end of the adjusting spring 620 is fixedly connected with the adjusting rod 610, and the other end is fixedly connected with the side wall of the positioning hole 320. One end of the adjusting lever 610 extends out of the threaded hole 210 and out of the positioning groove 412 under the elastic force of the adjusting spring 620. When the free end of the handle 100 rotates towards the direction close to the screw 300 and the side surface of the handle 100 is attached to the bottom of the positioning groove 412, the handle 100 is abutted to the adjusting rod 610, and the adjusting spring 620 is compressed, so that one end, far away from the handle 100, of the adjusting rod 610 penetrates into the strip-shaped hole 310 under the action of the handle 100 and is abutted to the baffle 311, the baffle 311 rotates, and two ends of the baffle 311 extend out of the strip-shaped hole 310; the free end of the handle 100 is rotated towards the direction far away from the screw 300, so that the abutting state of the handle 100 and the adjusting rod 610 is released, the adjusting rod 610 returns to the original position under the elastic force action of the adjusting spring 620, and the baffle 311 is rotated under the action of the self gravity until the two ends of the baffle are positioned in the strip-shaped holes 310.

In order to facilitate the worker to rotate the handle 100, the handle 100 drives the adjusting rod 610 to move, and a round corner is formed at one end of the adjusting rod 610 far away from the baffle 311.

Referring to fig. 3, when the side surface of the handle 100 abuts against the bottom of the limiting groove 410, and the worker rotates the handle 100 to overcome the restoring deformation force of the adjusting spring 620, the two side walls of the limiting groove 410 are correspondingly provided with grooves 411, and the handle 100 is integrally formed with a protrusion 110. When the handle 100 rotates to the side surface of the handle to abut against the bottom of the limiting groove 410, the protrusion 110 is in clamping fit with the groove 411, so that the handle 100 is not easy to rotate under the acting force of the adjusting spring 620, and the labor-saving effect is achieved.

The handle 100 is provided with a locking groove 120, and the side wall of the limiting groove 410 is provided with a positioning groove 412. In order to prevent the handle 100 and the bottom plate 400 from shaking when a worker holds the handle 100 and mounts the screw 300 to the mounting and dismounting hole of the spacer, the bottom plate 400 is provided with a control assembly 700 for controlling the rotation angle of the handle 100 and the bottom plate 400. The control assembly 700 includes a latch 720 and an elastic body 710 disposed in the positioning groove 412, the elastic body 710 is preferably a spring, one end of the spring is fixedly connected to the bottom of the positioning groove 412, and the other end of the spring is fixedly connected to the latch 720. Under the elastic force of the elastic body 710, one end of the latch 720 protrudes out of the positioning groove 412, and one end of the latch 720 protruding out of the positioning groove 412 is hemispherical. When the handle 100 is rotated to the state of abutting against the adjusting rod 610, the latch 720 is engaged with the engaging slot 120 under the elastic force of the elastic body 710.

In order to prevent the worker from slipping when holding the handle 100, the handle 100 is provided with anti-slip lines.

The implementation principle of the embodiment is as follows: the handle 100 is rotated until the handle 100 is released from the abutting state of the adjusting rod 610, that is, the latch 720 is engaged with the latch groove 120. Then, the screw 300 is put into the dismounting hole of the spacer, and the two positioning rods 500 are positioned at two sides of the spacer. The handle 100 is rotated to enable the side surface of the handle 100 to be attached to the bottom of the limiting groove 410, so that the handle 100 presses the adjusting rod 610, the adjusting spring 620 is compressed, the adjusting rod 610 slides towards the direction close to the baffle 311, the side surface of the adjusting rod 610 is attached to the side surface of the baffle 311, the handle 100 is continuously rotated, and the baffle 311 rotates under the action of the adjusting rod 610 until the two ends of the baffle 311 extend out of the strip-shaped holes 310. Rotate handle 100, handle 100 drives screw rod 300 and rotates, after baffle 311 and locating lever 500 butt, because locating lever 500's limiting displacement for baffle 311 drives screw rod 300 and can't continue to take place to rotate, thereby makes sleeve 200 and screw rod 300 take place relative rotation, and sleeve 200 diminishes with screw rod 300 coincidence interval promptly, so that baffle 311, bottom plate 400 and conductor spacer both ends butt.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
