Description

Technical Field

[0001] The utility model belongs to the technical field of tools and equipment, and particularly relates to a barrel cover opening wrench suitable for a pressure differential barrel body. Background Art

[0002] Small-mouth plastic differential pressure fertilizer applicator is an agricultural irrigation auxiliary equipment, which uses the pressure difference generated when water flows through a pipe of a specific shape to absorb fertilizer solution and transport it to the irrigation system so that the fertilizer can directly act on the roots of crops. This fertilizer applicator is usually composed of plastic pipe fittings, ball valves, fertilizer absorbers and other components. It is easy to operate, can achieve uniform fertilization, improve fertilizer efficiency, reduce waste, and save manpower and time.

[0003] However, after the use of this type of differential pressure barrel, the significant pressure difference between the inside and the outside causes the sealing cover on the top of the barrel to bear additional closing force, which makes the conventional rotation operation extremely difficult. For people with relatively weak strength, especially female operators, this operation is very inconvenient. Even for men with better physical fitness, if they need to open multiple such pressure vessels continuously, they will also face continuous physical tests and operational difficulties. This repetitive and high-intensity labor not only consumes a lot of energy, but may also affect work efficiency and user experience. Utility Model Content

[0004] In view of the above-mentioned problems, the purpose of the utility model is to provide a barrel cover opening wrench suitable for a pressure differential barrel body, which can easily open the barrel cover.

[0005] The technical solution of the utility model is: a barrel cover opening wrench suitable for a pressure differential barrel body, comprising:

[0006] A tube body, which is a cylinder;

[0007] Two sleeves are symmetrically and movably sleeved on both sides of the tube body, and each sleeve is provided with a fixing piece, and the fixing piece is used to fix the corresponding sleeve on the tube body;

[0008] Two clamping plates, the lower side of the inner end of each sleeve is rotatably connected to one of the clamping plates via a rotating shaft seat;

[0009] Two groups of collars, one group of collars is fixedly provided under each sleeve;

[0010] Two push rods, one push rod is movably sleeved in each set of the collars, one end of the push rod is connected to the outer side surface of the corresponding clamping plate through a hinge seat;

[0011] Two kneading handles, one of which is provided on the lower side of the outer end of each sleeve, each of which comprises a pin seat fixedly arranged below the sleeve and a handle body rotatably connected to the pin seat, the handle body having a kneading end and a rotating end, the rotating end being cam-shaped and in contact with the outer end of the push rod, and the rotating end rotates around the pin seat driven by the kneading end, thereby pushing the push rod.

[0012] Furthermore, the fixing member includes a fixing bolt penetrating through the upper surface of the sleeve.

[0013] Furthermore, one end of the push rod close to the kneading end is arc-shaped.

[0014] Furthermore, limiting sleeves are provided at both ends of the tube body.

[0015] Furthermore, the opposite sides of the two clamping plates are provided with anti-slip rubber layers.

[0016] Furthermore, the tube body is provided with scales.

[0017] The working method of the utility model is as follows: according to the thickness of the handle of the barrel cover, the distance between the two sleeves is adjusted so that the distance between the two clamping plates can be inserted into the barrel cover, and then the fixing bolts are tightened to fix the sleeve and the tube body, and then the two clamping plates are inserted on both sides of the barrel cover, and the operator holds the two ends of the tube body and pinches the pinching end of the handle body with fingers, and the rotating end of the handle body rotates under the action of the pin shaft seat, and the cam principle is used to press the push rod toward the inner end, thereby driving the clamping plate to apply clamping force to the barrel cover, and then the operator rotates the tube body to easily complete the removal of the barrel cover.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a barrel cover opening wrench suitable for a pressure differential barrel body, by arranging a symmetrical clamping plate in the middle of the tube body, the clamping plate can clamp the barrel cover handle, and at the same time, a push rod is arranged on the outside of the clamping plate, and a pinching handle is also arranged. By pinching the pinching handle, the push rod is pushed, thereby providing a clamping force to the clamping plate, so that the clamping plate can firmly clamp the barrel cover handle. The operator only needs to rotate the tube body to easily open the barrel cover, and by arranging a sleeve that can adjust the position, it can meet the use of barrel cover handles of different thicknesses. In short, the utility model has the advantages of novel structure, convenient use, labor saving and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
