Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and in particular to a waterproof cover for a peristaltic pump power socket. Background Technology

[0002] Peristaltic pumps are widely used in laboratories, pharmaceuticals, and chemical industries. Because peristaltic pumps handle liquids, they require a certain level of waterproofing; water ingress can cause damage. Laboratory peristaltic pumps have relatively low waterproofing requirements, generally requiring IPX1, which is sufficient to prevent vertical dripping. Most commercially available AC power sockets are not waterproof, making it difficult to achieve an IPX1 waterproof design. However, using an IP67 waterproof aviation socket to achieve a low waterproof rating is unreasonable and wasteful. The socket supplies power to the equipment and requires an external power plug, such as... Figure 6 As shown, the structure of this socket includes A, fuse holder, B, mounting hole, C, plug hole, D, coupler, and E, inner body. This socket design is not waterproof. If water enters the socket at points A, C, and E during the IPX1 test, it will affect the creepage clearance, causing the withstand voltage test to fail and the waterproof test to fail. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a waterproof cover for a peristaltic pump power socket, which achieves semi-enclosed protection for the socket, with the upper part completely sealed and the lower part open for easy installation and preventing water accumulation.

[0004] The technical solution adopted by this utility model is: a waterproof cover for a peristaltic pump power socket, including a sealing gasket and a sealing cover, wherein the sealing gasket and the sealing cover are integrally formed, the sealing gasket has a socket opening in the middle, the sealing cover has a plug hole corresponding to the socket opening, the sealing cover has an integrally formed water-blocking flange located on the outer ring of the plug hole and a sealing ring on the inner ring of the plug hole, and the lower end of the sealing cover has a notch.

[0005] Preferably, the sealing gasket and sealing cover are made of rubber, and more preferably silicone.

[0006] Preferably, screw mounting holes are provided at both ends of the sealing gasket.

[0007] Preferably, the sealing cover has misaligned holes corresponding to the screw mounting holes.

[0008] Preferably, the sealing gasket and sealing cover are arranged in a triangular shape.

[0009] Preferably, the outer opening of the misaligned hole is lower than the inner opening.

[0010] The beneficial effects of this utility model are as follows: By setting up a waterproof socket cover, a semi-enclosed protection for the socket is achieved. The upper part is completely sealed, while the lower part is open for easy installation and prevents water accumulation. During installation, the socket passes through the socket opening of the waterproof socket cover. Because the waterproof socket cover is made of rubber and can be deformed at will, screws can be passed through the screw mounting holes to install the waterproof socket cover onto the equipment housing. When the waterproof socket cover is installed onto the equipment housing, the waterproof gasket of the waterproof socket cover is pressed down by the mounting hole of the socket. The first layer of sealing between the socket and the equipment housing is achieved by tightening the screws, preventing water from entering the inner body of the socket. The upper part of the waterproof socket cover is a closed space, and the power cord plug is in close contact with the sealing ring of the waterproof socket cover. Water will not flow into the fuse holder, mounting hole, and inner body of the socket, achieving an IPX1 seal for the entire socket. This prevents water from entering the fuse holder, mounting hole, and inner body of the socket, affecting the creepage clearance, ensuring that the withstand voltage test is passed, and guaranteeing the success of the waterproof test.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0023] like Figures 1-5 As shown, this embodiment provides a waterproof cover for a peristaltic pump power socket, including a sealing gasket 1 and a sealing cover 2. The sealing gasket 1 and the sealing cover 2 are integrally formed. The sealing gasket 1 has a socket opening 3 in the middle. The sealing cover 2 has a plug hole 4 corresponding to the socket opening 3. The sealing cover 2 has a water-blocking flange 5 located on the outer ring of the plug hole 4 and a sealing ring 6 located on the inner ring of the plug hole 4. The lower end of the sealing cover 2 has a notch 7.

[0024] The sealing gasket 1 and sealing cover 2 are made of rubber, preferably silicone, and can be deformed arbitrarily.

[0025] Both ends of the sealing gasket 1 are provided with screw mounting holes 8, and the sealing cover 2 is provided with misaligned holes 9 corresponding to the screw mounting holes 8. When the socket is installed, because the socket waterproof cover is made of rubber and can be deformed at will, the screwdriver can be inserted through the misaligned hole 9 to tighten the screw 13. Moreover, the misaligned hole 9 can prevent water within 15° in the vertical direction from entering the interior, which can achieve IPX1-IPX2 waterproof requirements.

[0026] The sealing gasket 1 and the sealing cover 2 are arranged in a triangular shape.

[0027] The outer opening of the misaligned hole 9 is lower than the inner opening to prevent water from entering.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the waterproof socket cover provides semi-enclosed protection for the socket, with a completely sealed top and an open bottom for easy installation and to prevent water accumulation. During installation, if... Figure 6 , Figure 7 and Figure 8As shown, the socket passes through the socket opening 3 of the socket waterproof cover. Because the socket waterproof cover is made of rubber and can be deformed at will, the screw 13 can be passed through the screw mounting hole 8 to install the socket waterproof cover onto the equipment housing 11. When the socket waterproof cover is installed onto the equipment housing 11, the waterproof gasket 1 of the socket waterproof cover is blocked by the B of the current socket and the mounting hole (e.g., Figure 9 The socket is pressed down at the part shown, and the first layer of sealing between the socket and the device housing 11 is achieved by tightening the screw 13, preventing water from entering the socket's E and inner body (such as...). Figure 9 As shown), the upper part of the socket waterproof cover is a closed space, and the power cord plug 12 is in close contact with the sealing ring 6 of the socket waterproof cover, preventing water from flowing into the socket's A, fuse holder cover B, mounting hole and E, and inner body (as shown). Figure 9 At the location shown), an IPX1 seal is achieved for the entire socket, preventing water from entering the socket's A, fuse holder cover B, mounting holes and E, and inner body (as shown). Figure 9 The creepage gap at the location shown in the figure was affected, which ensured that the withstand voltage test passed and the waterproof test was successful.

[0030] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
