Description

Technical Field

[0001] The invention relates to the technical field of wrenches, and in particular to a ball valve power-assisted wrench which is easy to operate. Background Art

[0002] PVC ball valve, PPR (specifications larger than ) It is very laborious to open and close the ball valve, especially for some uncommon ball valves. It is impossible to open and close the valve with both hands at the same time. Some valves are difficult to open and close due to the limited or limited space available for human operation at the installation location, which is inconvenient to operate. After searching, the Chinese invention patent with patent application number CN202220794227.8 discloses a power wrench for a ball valve, including a lever arm; a palm handle is provided at one end of the lever arm, and one end of the palm handle is fixedly connected to one end of the lever arm, and the palm handle and the lever arm are located on the same plane; a positioning assembly is provided on one side of the palm handle, and the positioning assembly has a number of positioning rods, and a number of positioning through holes are provided on the palm handles corresponding to the number of positioning rods, and one end of the number of positioning rods can be detachably fixed on the number of positioning through holes. It has a simple structure, is easy to operate, easy to carry, has high opening and closing efficiency, a wide range of uses, and is suitable for people with less strength.

[0003] Another example is a Chinese invention patent with patent application number CN202021158688.3, ​​which discloses a high-altitude manual ball valve wrench. Its innovation lies in that the ball valve wrench includes a main handle and at least two support handles arranged perpendicularly to the main handle. When the main handle is in a vertical state, the at least two support handles are located on the same horizontal plane; the inner end of each support handle is fixedly connected to the top of the main handle, and a wrench head is fixedly provided on the outer end. A matching groove is provided on the outer end surface of the wrench head. The geometric center of the matching groove notch is located on the axis of the corresponding support handle, which is used to insert the valve stem of the ball valve to be opened; the cross-section of the matching groove is rectangular, and the length direction center line of each matching groove has a different angle with the horizontal plane. The present invention can solve the problem of inconvenient operation of high-altitude manual ball valves in a simple, flexible and low-cost manner.

[0004] Although the above-mentioned ball valve wrench can meet the basic needs of opening and closing the ball valve, during use, the force-bearing area of ​​the ball valve is small, and it is easy to damage the ball valve due to excessive force. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0005] The technical problem to be solved by the present invention is that, in view of the above-mentioned defects of the prior art, a ball valve power-assisted wrench that is easy to operate is provided. A sleeve is arranged to be sleeved on the valve stem of the ball valve, and the ball valve is opened or closed with the help of an extended handle, which saves effort and facilitates operation. A clamping guard plate is arranged to increase the contact area between the sleeve and the valve stem, thereby increasing the force area of ​​the ball valve, avoiding damage to the ball valve due to excessive force, and facilitating the next operation.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A ball valve power-assisted wrench that is easy to operate comprises an extended handle and a sleeve. The extended handle is inserted into the upper end of the sleeve. A ball valve sleeve through hole is provided at the bottom of the sleeve. A front clamping groove and a rear clamping groove are respectively provided at the bottom of the front and rear ends of the sleeve. A plurality of clamping guard plates are provided on the outer sides of the front clamping groove and the outer sides of the rear clamping groove.

[0008] Preferably, the clamping guard plate includes a first clamping guard plate, a second clamping guard plate, a third clamping guard plate and a fourth clamping guard plate, and the first clamping guard plate and the second clamping guard plate are symmetrically arranged on the outer side of the front clamping groove.

[0009] Preferably, the third clamping guard plate and the fourth clamping guard plate are symmetrically arranged on the outer side of the rear clamping groove.

[0010] Preferably, a plurality of handle insertion through holes for inserting the extended handle are provided on the outer side of the upper end of the sleeve.

[0011] Preferably, the handle plug-in hole comprises a first handle plug-in hole, a second handle plug-in hole, a third handle plug-in hole and a fourth handle plug-in hole, and the first handle plug-in hole and the second handle plug-in hole are symmetrically arranged on the left and right outer sides of the sleeve.

[0012] Preferably, the third handle inserting through hole and the fourth handle inserting through hole are symmetrically arranged on the front and rear outer sides of the sleeve.

[0013] The invention adopts the above technical scheme, and provides a ball valve power-assisted wrench which is easy to operate, and has the following beneficial effects: the extended handle in the ball valve power-assisted wrench is inserted into the upper end of the sleeve, and a ball valve sleeve through hole is provided at the bottom of the sleeve, and a front clamping groove and a rear clamping groove are respectively provided at the bottoms of the front and rear ends of the sleeve, and a plurality of clamping guard plates are provided on the outer sides of the front clamping groove and the outer sides of the rear clamping groove. The sleeve is set to be sleeved on the valve stem of the ball valve, and when in use, the bottom of the sleeve is sleeved on the outer side of the valve stem of the ball valve, so that the inner side of the clamping guard plate is against the valve stem, and the ball valve is opened or closed in cooperation with the extended handle, which plays a labor-saving role and is convenient for operation. The contact area between the sleeve and the valve stem is increased by setting the clamping guard plate, and then the force-bearing area of ​​the ball valve is increased, so as to avoid the situation that the ball valve is damaged due to excessive force. The invention is more stable and reliable, can ensure that the valve stem rotates accurately during operation, and the opening and closing of the valve can be easily operated, and can be sleeved on the ball valve for the convenience of the next operation. The overall structure is relatively simple, easy to process, and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS
