Description

Technical Field

[0001] This utility model relates to the field of leather bowl technology, specifically a leak-proof leather bowl. Background Technology

[0002] A cup is a seal, typically made of rubber, polyurethane, or other elastic materials, used to create a dynamic seal within the pump chamber, ensuring unidirectional fluid flow and preventing leakage.

[0003] The existing leather bowls have the following problems:

[0004] The existing leather cup has a simple structure and relatively poor sealing performance. Furthermore, it requires alignment during installation, which may lead to misalignment and the need for reinstallation. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof leather bowl to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof leather cup, including a movable rod, a leather cup provided on the movable rod, a pressure plate provided on the leather cup, a locking fastener connected in the pressure plate, a movable edge provided on the edge of the leather cup, and a fixing member provided inside the leather cup.

[0007] Preferably, the end of the fixing member is provided with an elastic element that extends into the movable side.

[0008] Preferably, the leather cup is provided with an installation port, and when the installation port is not under force and is in its natural state, the diameter of the installation port is smaller than that of the movable rod.

[0009] Preferably, the surface of the leather cup is provided with a locking element, and the pressure plate is provided with a positioning port.

[0010] Preferably, the positioning component is provided with a shaping ring.

[0011] Preferably, the movable edge surface is provided with a support ring, and when the movable edge is pressed, the support ring abuts against the surface of the cup.

[0012] Preferably, the support ring has an opening for movement.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the rubber cup is installed in the pump pipe, the rubber cup will be compressed, and the movable side will also be stressed and generate elastic force, causing it to deform and bend. Under the action of elastic force, it will tightly fit against the inner wall of the pump pipe. The elastic element will also be stressed and deformed, so that the movable side can firmly fit against the inner wall surface of the pump pipe, thereby improving the sealing performance of the rubber cup and effectively reducing the phenomenon of gaps at the pipe opening, thus achieving a leak-proof effect.

[0015] The mounting port allows for centered installation of the leather cup, preventing inaccurate installation. Furthermore, the mounting port can be clamped onto the movable rod for pre-fixation, enhancing the ease of installation.

[0016] When the pressure plate is installed on the leather cup, the positioning port will align with the locking component to ensure that the pressure plate can press better against the surface of the leather cup. After the pressure plate is fixed, it will ensure that the leather cup will not be misaligned, thus improving the stability of the installation. Attached Figure Description

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 and Figure 2 This utility model provides a leak-proof leather cup, including a movable rod 1, a leather cup 2 disposed on the movable rod 1, a pressure plate 3 disposed on the leather cup 2, and a locking fastener 4 connected in the pressure plate 3.

[0024] Specifically, the cup 2 is placed on the movable rod 1, and then the pressure plate 3 is pressed into the middle of the cup 2. Next, the locking fastener 4 passes through the pressure plate 3 and the cup 2 and is threaded to the movable rod 1, thereby fixing the cup 2 on the movable rod 1. After the pressure plate 3 is installed in the pump tube, it will be pressurized and thus sealed in the pump tube.

[0025] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides a leak-proof leather cup. The leather cup 2 has a movable edge 21 integrally formed on its side. A fixing member 22 is fixed inside the leather cup 2. An elastic member 221 is integrally formed at the end of the fixing member 22 and extends into the movable edge 21. A support ring 27 is integrally formed on the surface of the movable edge 21. When the movable edge 21 is compressed, the support ring 27 abuts against the surface of the leather cup 2, thereby supporting the movable edge 21, reducing excessive deformation, and improving the sealing performance. The support ring 27 has an opening 28, which allows the support ring 27 to deform under force, thereby supporting the movable edge 21.

[0026] Specifically, when the rubber cup 2 is installed in the pump pipe, the rubber cup 2 will be compressed, and the movable edge 21 will also be stressed and generate elastic force, and deform and bend. Under the action of elastic force, it will be tightly attached to the inner wall of the pump pipe. At this time, the fixing part 22 can ensure that the outer ring of the rubber cup 2 is not easily deformed. When the movable edge 21 deforms, the elastic part 221 will also be stressed and deformed, so that the movable edge 21 can be firmly attached to the inner wall surface of the pump pipe, thereby improving the sealing performance of the rubber cup 2, effectively reducing the phenomenon of gaps at the floor opening, and having a leak-proof effect.

[0027] The leather cup 2 is provided with an installation port 23. When the installation port 23 is not under force and is in its natural state, the diameter of the installation port 23 is smaller than that of the movable rod 1. When the leather cup 2 is installed on the movable rod 1, the installation port 23 can be installed in the center, avoiding inaccurate installation. Moreover, the installation port 23 can also be clamped on the movable rod 1 to achieve pre-fixation, which improves the convenience of installation.

[0028] The surface of the leather cup 2 is provided with a locking component 24, and the pressure plate 3 is provided with a positioning port 25. The locking component 24 is provided with a shaping ring 26. When the pressure plate 3 is installed on the leather cup 2, the positioning port 25 will align with the locking component 24, so that the pressure plate 3 can be pressed more firmly on the surface of the leather cup 2. After the pressure plate 3 is fixed, it ensures that the leather cup 2 will not be misaligned, thus improving the stability of the installation.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
