Description
Technical Field
[0001] The utility model relates to the technical field of water pumps and oil pumps, in particular to a detachable plunger. Background Art
[0002] As people's living standards improve, the number of cars owned is also increasing. At present, commonly used car washing devices mainly include car washing machines, water tanks and water spray heads. Among them, high-pressure water gun car washing machines often include plunger pumps, which use power to drive the plunger in the plunger pump to reciprocate, thereby achieving high-pressure water gun cleaning.
[0003] The plunger in the existing car washing machine plunger pump is generally an integrally formed fixed part. For example, the lever-type plunger pump and cleaning machine with publication number CN216407069U discloses a plunger 20 of an integral structure. The middle part of the plunger 20 is provided with a clamping portion 23 which is combined with the connecting portion 32 on the swing rod 31. The connecting portion 32 is tightly matched with the clamping portion 23, and the plunger 20 is driven to reciprocate back and forth through the connecting portion 32.
[0004] Obviously, during the operation of the cleaning machine, the clamping part on the plunger is easily damaged, resulting in the scrapping and replacement of the plunger. The cost of using the plunger is high, and it will also affect the effectiveness of the car washing machine. In addition, the one-piece structure plunger has a small volume, and the clamping part and other structures are processed on its main body. The processing accuracy requirements are also very high, and the processing difficulty is great. Utility Model Content
[0005] The utility model aims to provide a detachable plunger to solve the problems in the prior art that the integrated plunger is easily damaged during use, has high processing requirements, and has high use and processing costs.
[0006] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:
[0007] A detachable plunger comprises a plunger body and a connecting sleeve, a fixing block and two connecting heads are integrally formed on the plunger body, the fixing block is located between the two connecting heads, a card slot is provided on the fixing block, and the two connecting heads are detachably connected with the connecting sleeve.
[0008] Preferably, a connecting column and a connecting groove are integrally formed on the connecting sleeve, and a cylindrical groove is provided in the connecting column.
[0009] Preferably, the inner wall of the connecting sleeve is provided with an internal thread, and the outer wall of the connecting head is correspondingly provided with an external thread.
[0010] Preferably, the fixing block is further formed with two fixing ends, one side of the fixing end is a card slot, and the other side is a connector.
[0011] Preferably, the plunger body is a plastic part, and the connecting sleeve is a metal part.
[0012] Compared with the prior art, the utility model has the following beneficial effects: the plunger of the utility model has a simple structure. By splitting the plunger into a plunger body and a connecting sleeve, on the one hand, it is convenient for processing a single accessory and improving processing accuracy and efficiency; on the other hand, the flexible detachable installation method is simple to operate, the installation accuracy is easy to control, and it is also convenient for replacing a single worn accessory, thereby improving the effectiveness of the plunger and the efficiency of the car washing machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a schematic diagram of the split structure of the utility model.
[0015] In the figure: 1- plunger body; 2- connecting sleeve; 101- fixing block; 102- connecting head; 103- slot; 104- fixing end; 201- connecting column; 202- connecting slot; 203- cylindrical slot. DETAILED DESCRIPTION
[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0017] like Figure 1-2 As shown, a detachable plunger comprises a plunger body 1 and a connecting sleeve 2. A fixing block 101 and two connecting heads 102 are integrally formed on the plunger body 1. The fixing block 101 is located in the middle of the two connecting heads 102. A card slot 103 is provided on the fixing block 101. Both the two connecting heads 102 are detachably connected with the connecting sleeve 2.
[0018] When in use, according to the use requirements, the connecting sleeve 2 is installed on the two joints 102 through a detachable connection method such as a thread to form the required plunger, and then the plunger is installed on the required plunger pump, and finally the plunger pump is installed on the car washing machine. The installation operation is relatively convenient.
[0019] The plunger of the utility model has a simple structure. By splitting the plunger into a plunger body 1 and a connecting sleeve 2, on the one hand, it is convenient for processing a single accessory and improves processing accuracy and processing efficiency. On the other hand, the flexible detachable installation method is simple to operate, the installation accuracy is easy to control, and it is also convenient to replace a single worn accessory, thereby improving the effectiveness of the plunger and the efficiency of the car washing machine.
[0020] Specifically, the connecting sleeve 2 is integrally formed with a connecting column 201 and a connecting groove 202, and a cylindrical groove 203 is provided in the connecting column 201. The above design uses the connecting sleeve 2 as a segmented structure, which can improve the use strength of the connecting sleeve 2; the bottom of the cylindrical groove 203 can be sealed, and in this case, vacuum suction of flowing liquids such as water and oil can be performed, or it can be designed to communicate with the connecting groove 202, which can improve the connection stability between the connector 102 and the connecting groove 202.
[0021] Specifically, the inner wall of the connecting sleeve 2 is provided with an internal thread, and the outer wall of the connecting head 102 is correspondingly provided with an external thread. The above structural design is simple and easy to process, has low processing cost, is easy to control processing accuracy, and is also convenient for disassembly and assembly.
[0022] Specifically, two fixed ends 104 are formed on the fixed block 101, one side of the fixed end 104 is the card slot 103, and the other side is the connector 102. The above design and the formation of the fixed end 104 form a certain distance between the connector 102 and the card slot 103, so that when the plunger moves back and forth, the vibration force generated by the card slot 103 will not directly affect the connector 102, that is, the risk of loosening of the connector 102 and the connecting sleeve 2 can be reduced, and the stability of the plunger can be improved.
[0023] Specifically, the plunger body 1 is a plastic part, and the connecting sleeve 2 is a metal part. The above design can flexibly select the materials of the plunger body 1 and the connecting sleeve 2, which can not only reduce the processing cost, but also improve the processing accuracy and the overall use stability of the plunger.
[0024] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
