Abstract
Description
Technical Field
[0001] This utility model relates to the field of push pumps, and in particular to a limit buckle and a push pump. Background Technology
[0002] Existing push pumps are equipped with a latch that prevents the pump from pressing down when not in use by locking the retaining ring at the press head.
[0003] For example, patent document CN221965701 U discloses an impact-resistant press pump comprising a press head, a fixing part, and a clamp. The press head has a sleeve and a support ring disposed on the outer side of the sleeve, the support ring being spaced apart from the sleeve to form a gap between the support ring and the sleeve. The clamp includes an annular support portion and at least one limiting portion formed on the inner surface of the support portion.
[0004] For example, patent document CN116673150A discloses a push-button pump with a limiting component to prevent loss, comprising: a cover body with an arc groove at the upper end; a main pump disposed on the cover body, the main pump including a piston rod that can move up and down relative to the cover body; a push-button connected to the upper end of the piston rod, the push-button being able to move up and down with the piston rod to have a first path; and a limiting component having an arc plate adapted to the arc groove, the arc plate being movable in the arc groove, and the limiting component being able to move along the arc groove to have a first position and a second position.
[0005] However, the above technology can only prevent the pressing head from pressing down through the latch, but cannot control the amount of pressing down of the pressing head.
[0006] To address this issue, a limit buckle and a pressing pump are proposed to solve the aforementioned technical problems. Utility Model Content
[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a press pump with the advantages of simple structure and controllable pressing head pressure, thereby facilitating control of liquid output.
[0008] The technical solution adopted by this utility model to solve the problem is: a limiting buckle, including: a handle, one end of the handle is provided with multiple retaining rings, the retaining rings are elastic, one side of the retaining rings is open, and the multiple retaining rings are of different heights.
[0009] A push-button pump includes a limiting buckle and a body. A spring is provided inside the body, and a piston is provided on the top of the spring. The piston is slidably connected to the body in a sealed manner. A main column is drivenly mounted on the top of the piston. A one-way valve is provided inside the main column. A pressing head is provided at the top of the main column, and a liquid outlet is provided on the pressing head. The liquid outlet, the main column, and the body are connected in sequence. The main column is adapted to a retaining ring.
[0010] As a further improvement to the above technical solution, the one-way valve includes a mounting base, which is fixedly installed on the top of the main column. The mounting base is funnel-shaped and contains a ball valve with a diameter larger than the bottom diameter of the mounting base.
[0011] As a further improvement to the above technical solution, it also includes a tooth cover, wherein the body is threadedly connected to the tooth cover, and the limiting buckle is located between the tooth cover and the pressing head.
[0012] The beneficial effects of this utility model are: by setting retaining rings of different heights to restrict the pressing head, the liquid output can be controlled. The structure is simple and highly practical. Attached Figure Description

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0022] Reference Figure 1 A limiting buckle includes: a handle 1, one end of the handle 1 is provided with multiple retaining rings 2, the retaining rings 2 are elastic, one side of the retaining rings 2 is an opening 21, and the multiple retaining rings 2 are of different heights.
[0023] Reference Figure 2-3 A push-button pump includes a limit latch and a body 4. A spring 41 is located inside the body 4, and a piston 42 is located on top of the spring 41. The piston 42 is slidably connected to the body 4. A main column 5 is drivenly mounted on top of the piston 42. A one-way valve is located inside the main column 5, and a push-button head 6 is located at the top of the main column 5. A liquid outlet 61 is located on the push-button head 6. The liquid outlet 61, the main column 5, and the body 4 are sequentially connected. The main column 5 is adapted to a retaining ring 2. In use, pressing down the push-button head 6 opens the one-way valve under air pressure, allowing gas or liquid inside the body 4 to be squeezed upwards and discharged through the liquid outlet 61. After stopping pressing down the push-button head 6, the piston 42 moves upwards under the elastic force of the spring 41, closing the one-way valve and allowing liquid to be drawn into the body 4. Repeating this operation allows for liquid extraction.
[0024] In a preferred embodiment, the one-way valve includes a mounting base 51, which is fixedly mounted on the top of the main column 5. The mounting base 51 is funnel-shaped, and a ball valve 52 is disposed inside the mounting base 51. The diameter of the ball valve 52 is larger than the bottom diameter of the mounting base 51. Under the action of gravity, the ball valve 52 seals with the bottom of the mounting base 51. When the pressing head 6 is pressed down, the ball valve 52 moves upward under the action of air pressure. Since the mounting base 51 is funnel-shaped, with the diameter increasing sequentially from the bottom to the top, the ball valve 52 no longer seals.
[0025] In a preferred embodiment, the device also includes a tooth cover 3, with the body 4 threadedly connected to the tooth cover 3, and a limiting buckle located between the tooth cover 3 and the pressing head 6.
[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
