Description
A crow bar with overload protection function
Technical field
This utility model involves a crow bar with overload protection function. Background technology
Crow bar is a common hardware tool. Goods can be pried via crow bar. However, crow bars in existing technologies have a simple structure. It is necessary to use a pivot in the use process. Meanwhile, crow bars in existing technologies do not have the function of overload protection in the use process. When the force is excessive, crow bar easily buckles, thus causing the accumulation of internal stress in the crow bar and the reduction of its strength and influencing its service life.
Invention content
The technical problem to be solved by this utility model is to provide a crow bar with overload protection function. When this device is used, stress block acts as the pivot. Therefore, it is unnecessary to draw support from other pivots in the use process. This device is easy to operate. Meanwhile, its protection axis pin can realize protective effect. When the force applied on stress block is excessive, the protection axis pin breaks off and the stress block loses its effect of pivot, thus protecting this device from damage. It is only necessary to replace the protection axis pin then. The nonslip sleeve can improve the degree of comfort and reduce bleeding blisters of workers due to long-time work.
To solve problems above, this utility model adopts the following technical scheme: A crow bar with overload protection function includes bearing plate. Bearing hole is set up in the middle position of the bearing plate mentioned. Through-hole is set up on the front end face of the bearing plate mentioned. The through-hole runs through the bearing hole mentioned. Guide slot is set up on the wall of the bearing hole mentioned. Protection axis pin is arranged in the through-hole mentioned. Stress block is set up at the bottom of the bearing hole mentioned. Locating block is set up on the top of the stress block mentioned. A locating hole fitting with the protection axis pin mentioned is set up on the top of the locating block mentioned. Guide bar fitting with the guide slot mentioned is set up on the outer ring of the stress block mentioned. Mounting sleeve is set up on the top of the bearing plate close to its left side. The mounting sleeve mentioned is upward sloping. Handlebar is set up in the mounting sleeve mentioned. Screw is arranged between the handlebar and the mounting sleeve mentioned. Nonslip base plate is set up on the top of the bearing plate mentioned close to its right end. Groove is set up in the middle position of the handlebar mentioned and at the end of the handlebar mentioned away from the bearing plate mentioned. Nonslip sleeve is set up in the groove. The nonslip sleeve and the handlebar mentioned are permanently connected.
Preferably, over two stiffeners are set up symmetrically at the bottom of the bearing plate mentioned. Stiffeners and the bearing plate mentioned are welded together.
Preferably, when the stress block mentioned is arranged in the bearing hole mentioned, the lower end face of the stress block mentioned extends to the exterior of the bearing hole mentioned.
Preferably, rib plates No.1 and No.2 are arranged between the mounting sleeve and the bearing plate mentioned.
Preferably, four external corners of the bearing plate mentioned have circular arc transition.
Beneficial effect of this utility model: when this device is used, stress block acts as the pivot. Therefore, it is unnecessary to draw support from other pivots in the use process. This device is easy to operate. Meanwhile, its protection axis pin can realize protective effect. When the force applied on stress block is excessive, the protection axis pin breaks off and the stress block loses its effect of pivot, thus protecting this device from damage. It is only necessary to replace the protection axis pin then. The nonslip sleeve can improve the degree of comfort and reduce bleeding blisters of workers due to long-time work. This device has simple structure and low costs and is suitable for promotion for use.
