Description

Technical Field

[0001] The invention relates to the technical field of insulating tools, in particular to an insulating clamp. Background Art

[0002] During live working, various insulating tools are needed to work away from live parts. Insulating clamps are one of the commonly used insulating tools. With the help of insulating clamps, workers can clamp and fix live parts at a safe distance.

[0003] However, the existing insulating clamps have a complex structure and are complicated to operate. In addition, during the clamping process, the operator needs to hold the clamp handle tightly. If the handle is released, the clamped object will be loosened, which not only increases the labor intensity, but also makes it impossible for the operator to free both hands to operate other insulating tools for the next step. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an insulating clamp.

[0005] The technical solution of the present invention is: an insulating clamp, comprising an insulating clamp body, wherein the insulating clamp body comprises a first clamping jaw and a second clamping jaw, a pivoting mechanism, an insulating gripping rod, and an insulating handle;

[0006] The first clamping jaw and the second clamping jaw are symmetrically arranged on the pivot mechanism, and the first clamping jaw and the second clamping jaw are controlled by the pivot mechanism to rotate toward or relative to each other at a certain angle;

[0007] The pivot mechanism is arranged in the insulating hand-held rod, and the pivot mechanism cooperates with the pressing mechanism arranged in the insulating handle.

[0008] Preferably, the pivot mechanism comprises a connecting rod, an adjusting screw, and a first adjusting shaft and a second adjusting shaft, wherein the connecting rod is installed in the insulating handle bar, and the upper end of the connecting rod is connected to the adjusting screw, and the lower end of the connecting rod is connected to a fixing rod;

[0009] The first adjusting shaft and the second adjusting shaft are both provided with corresponding racks, and the first adjusting shaft and the second adjusting shaft are meshed with the racks on the adjusting screw through the racks thereon;

[0010] And the first adjusting shaft and the second adjusting shaft are respectively connected with a first clamping jaw and a second clamping jaw.

[0011] Preferably, a chamber for accommodating the pressing mechanism is provided in the insulating handle, and the upper end of the chamber has a through hole for inserting the fixing rod, and the lower end of the chamber is provided with a notch.

[0012] Preferably, the pressing mechanism includes a pressing handle, a sleeve, and a spring. The sleeve is located in the chamber, and a socket for inserting a fixing rod is provided at the upper end of the sleeve, and the spring is sleeved on the fixing rod and contacts the outer wall of the sleeve. The pressing handle is rotatably arranged at the notch at the lower end of the chamber through a fixed shaft, and one end of the pressing handle is located at the lower end of the sleeve, and the other end extends out of the notch. By pressing the pressing handle, the pressing handle located at the lower end of the sleeve pushes the sleeve upward, and the sleeve moves upward in the chamber, so that the fixing rod is inserted into the sleeve, and then the insulating handle is manually twisted, and the insulating handle drives the sleeve inside it to rotate together, thereby driving the connecting rod connected to the fixing rod to rotate together through the sleeve. During the rotation of the connecting rod, the adjusting screw is driven to rotate. Since the adjusting screw is engaged with the first adjusting shaft and the second adjusting shaft, the first adjusting shaft and the second adjusting shaft are driven to rotate, thereby driving the first clamp and the second clamp to clamp or release. When the pressing handle is released, the sleeve is separated from the connecting rod due to the action of the spring.

[0013] Preferably, the rack on the adjusting screw is a spiral rack inclined upward.

[0014] Preferably, the racks on the first adjusting shaft and the second adjusting shaft are elliptical racks. When the racks of the first adjusting shaft and the second adjusting shaft are clamped in the grooves of the racks of the adjusting screw, the first adjusting shaft and the second adjusting shaft are fixed, so that the first clamp and the second clamp can clamp the corresponding objects.

[0015] Preferably, the first adjustment shaft and the second adjustment shaft rotate synchronously and in opposite directions.

[0016] Preferably, the first clamping jaw and the second clamping jaw have the same structure and both comprise a clamping jaw seat and a plurality of clamping plates arranged on the clamping jaw seat, and each of the clamping plates is provided with a plurality of uniformly distributed clamping teeth.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention has a simple structure and strong practicality. The present invention realizes the mutual cooperation of driving the first clamping jaw and the second clamping jaw by cooperating with the screw rod and the rack on the adjusting shaft, thereby realizing clamping or loosening;

[0019] 2. The present invention realizes the mutual cooperation between the first clamping jaw and the second clamping jaw by rotating the screw rod. Therefore, when the pressing handle is released and the screw rod is not rotated, the clamped first clamping jaw and the second clamping jaw have the function of preventing loosening. The operation is simple and there is no need to press the main pressing handle all the time, thereby freeing the hands and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
