Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary pistons, in particular to an auxiliary piston that can prevent tilting. Background Art

[0002] A spray pump is a device used to convert liquid into mist. It usually consists of a container, a nozzle and a pressure pump. The working principle of the spray pump is to manually or automatically operate the liquid in the container to be pumped to the nozzle by pressure, and then the liquid is converted into mist and sprayed out through the atomization effect of the nozzle.

[0003] In the assembly of the spray pump, the secondary piston is usually installed in the cylinder of the pressure pump. The secondary piston adjusts the pressure in the cylinder by moving, thereby controlling the flow rate and injection effect of the liquid. In the prior art, a shock-resistant and anti-deviating biopharmaceutical spray pump (publication number: CN217886704U) is installed with a first spring between the main piston and the main column, and the secondary piston is connected to the second spring to achieve a shock-absorbing effect. However, the secondary piston in the device is prone to tilting and shaking, so the secondary piston is easily crushed during the assembly process of the device. Therefore, it is urgent to design a secondary piston that can prevent tilting during assembly. Utility Model Content

[0004] The utility model aims to solve the disadvantages in the prior art that the auxiliary piston is easy to tilt and shake during the assembly process of the spray pump, and is thus easy to be crushed, and proposes an auxiliary piston that can prevent tilting.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tilt-preventing auxiliary piston comprises an auxiliary piston body, wherein a first connection end is fixedly mounted on the top of the auxiliary piston body, the bottom of the auxiliary piston body is an open structure, a second connection end is fixedly mounted in the auxiliary piston body, and a plurality of limit blocks are arranged on the surface of the auxiliary piston body.

[0007] As a further technical solution of the utility model, a plurality of the limit blocks are evenly distributed on a circumference, and a slope is provided on one end of each of the limit blocks.

[0008] As a further technical solution of the utility model, a groove for positioning and limiting is formed between every two of the limit blocks.

[0009] As a further technical solution of the utility model, a convex rafter is provided on the inner side of the opening at the bottom end of the auxiliary piston body.

[0010] The beneficial effects of the utility model are:

[0011] By setting the first connecting end and the second connecting end, positioning can be performed more conveniently during assembly, and multiple limit blocks can be provided for limited assembly of parts compatible therewith, thereby improving the stability after assembly. The limit blocks can also play an anti-slip effect during the assembly process, thereby effectively avoiding the tilting and shaking of the auxiliary piston body during assembly, thereby improving the stability of the equipment during use.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Through the setting of the device in combination with the first connecting end 2 and the second connecting end 4, the accuracy of the device during assembly can be increased, thereby improving the assembly efficiency. The setting of a plurality of limit blocks 3 evenly distributed around the circumference not only makes the assembly process have an anti-slip effect, but also improves the stability of the device after assembly.

[0020] Please see attached Figure 2 and attached Figure 3 In a preferred embodiment, a plurality of limit blocks 3 are evenly distributed on the circumference, a slope is provided on one end of each limit block 3, a groove for positioning and limiting is formed between every two limit blocks 3, a convex rafter 5 is provided on the inner side of the bottom opening of the auxiliary piston body 1, and a plurality of limit blocks 3 are evenly distributed on the circumference, so that the aesthetics of the auxiliary piston body 1 is improved. After assembly, the convex rafter 5 can be used with a sealing ring, and the auxiliary piston and the sealing ring together form a closed space to prevent liquid leakage and improve the sealing of the equipment.

[0021] Working principle: First, turn the cylinder of the pressure pump upside down and place it on a stable workbench, making sure the surface of the workbench is smooth; then insert the auxiliary piston body 1 into the cylinder, and make sure it can move smoothly in the cylinder. The auxiliary piston body 1 should be in close contact with the inner wall of the cylinder, but not too tight, to ensure its smooth movement; finally, make sure the sealing ring or gasket is intact and correctly installed on the convex rafter 5 of the auxiliary piston body 1 to ensure that pressure can be generated.
