Description

Technical Field

[0001] This utility model belongs to the field of anti-slip pump pipe technology, and relates to a pump pipe interface anti-disconnection device. Background Technology

[0002] The main drawbacks of existing anti-slip pump tubing in terms of pressure separation at the tubing interface are unstable sealing performance and insufficient mechanical connection reliability. Unstable sealing performance is usually caused by aging or wear of the sealing material at the tubing interface, or improper installation, which may lead to leakage at the interface under high pressure, affecting pumping efficiency and safety. Insufficient mechanical connection reliability is due to potential defects in the interface design, such as thread wear or loose locking devices. These can easily lead to interface separation during high-pressure operations, causing pump tubing failure or even safety accidents.

[0003] Conventional solutions include regularly inspecting and replacing sealing materials, strengthening and maintaining joints, and using higher-quality pump tubing and fittings. However, these methods require frequent manual intervention and maintenance, increasing operating costs and downtime, and do not fundamentally address design flaws, only alleviating the problem to some extent. Furthermore, even with regular maintenance, the risk of accidents remains due to operator negligence or inadequate maintenance. Therefore, there is an urgent need for a pump tubing joint anti-disengagement device to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pump pipe interface anti-disconnection device to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a pump pipe interface anti-disengagement device, comprising: a side head and an inner sleeve, wherein the left end of the side head is provided with a set of limiting seats for abutting against the left side of the inner core, and the right side of the limiting seats is provided with a set of inner cores for preventing the side head and the side head from disengaging and separating.

[0006] The inner core includes an embedded head and an inner cavity. The top view of the inner core is an isosceles trapezoidal structure. The diameter of the left cross-section of the inner core is greater than the length of the right cross-section of the inner core. The inner core is a deformable structure. The inner wall of the inner core has several sets of internal deformation grooves to facilitate its compression deformation.

[0007] In a preferred embodiment, the length of the inner deformation groove in plan view is less than the length of the inner core in plan view, and several sets of inner deformation grooves are staggered left and right, with a set of inner positioning grooves provided at the non-grooved end of each set of inner deformation grooves.

[0008] In a preferred embodiment, the inner positioning groove has a circular cross-section when viewed from above, and is located in the same space as the inner deformation groove. The diameter of the inner positioning groove when viewed from above is larger than the width of the inner deformation groove.

[0009] In a preferred embodiment, the inner core has a set of embedded heads on its left side. These embedded heads are interlocked and abut against the right side of the limiting seat. The right side of the core sleeve is sealed and fitted with the embedded tube sleeve. When the operator seals and installs the external pipe connecting the first side head to the inside of the anti-slip pump and seals and connects the second side head to the end of the anti-slip pump, the pressurized liquid is introduced into the anti-slip pump through the external pipe. The inner core will exert pressure due to the pressure of the pressurized liquid itself. The left side of the embedded tube sleeve and the right side of the limiting seat are in contact with the right and left sides of the inner core. When the components are interlocked, the embedded pipes and limiting seats are sealed and fitted with the inner core, allowing pressurized liquid to flow through the inner core. At the same time, they are sealed and fitted with side head one and side head two. Positioning holes one and two are locked in place by external locking devices, thus ensuring that side head one and side head two are sealed and connected to the left and right sides of the inner core. Meanwhile, when the deformation groove recovers and releases stress during installation, it provides a holding state for side head one and side head two, ensuring that side head one and side head two cannot be disengaged.

[0010] In a preferred embodiment, the left side structure of the embedded sleeve is the same as the right side structure of the limiting seat, but the inner diameters are different. When the left side of the embedded sleeve and the right side of the limiting seat are fitted and abutted against the right and left sides of the inner core, the embedded pipe and the limiting seat are sealed and fitted with the inner core.

[0011] In a preferred embodiment, the outer side of the limiting insert is provided with a set of inner sealing sleeves for maintaining the positioning and sealing of the inner core. The right side of the inner sealing sleeve is provided with a set of side heads two for sealing connection with the anti-slip pump. When the inner core is in contact with the limiting insert, the limiting insert can effectively maintain the stability of the inner core between side heads one and side heads two during the flow of pressurized liquid, thereby avoiding gaps between side heads one and side heads two and the inner core, preventing pressurized liquid from seeping out from the gaps, and separating side heads one and side heads two from the inner core by the tension of the pressurized liquid itself.

[0012] In a preferred embodiment, the left side of the first side head is provided with a set of external pipes for connecting with the inside of the anti-slip pump. The external pipes are sealed to the inside of the first side head. Both the first and second side heads are provided with several sets of positioning holes one and positioning holes two.

[0013] In a preferred embodiment, the first positioning hole is coaxially arranged with the inner positioning groove on the left side of the inner core, and the second positioning hole is coaxially arranged with the inner positioning groove on the right side of the inner core. The outer side of the left end of the embedded tube sleeve is provided with an external thread, and the inner side of the right end of the first side head is provided with an internal thread groove. The first side head is threadedly engaged with the embedded tube sleeve.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the pressurized liquid is introduced into the anti-slip pump through the external pipe fitting, the inner core will generate pressure due to the pressure of the pressurized liquid itself. When the left side of its embedded sleeve and the right side of the limiting seat are fitted and abutted with the right and left sides of the inner core, the embedded pipe and the limiting seat are sealed and fitted with the inner core, which allows the pressurized liquid to flow through the inside of the inner core. At the same time, it is sealed and fitted with the first and second side heads. The first and second positioning holes are locked by external locking parts to ensure that the first and second side heads and the left and right sides of the inner core are kept in a sealed connection state. At the same time, when its own deformation groove recovers and releases stress during the installation process, it provides a tight holding state for the first and second side heads to ensure that the first and second side heads cannot be dislodged.

[0015] When the inner core is in contact with the limiting insert, the limiting insert can effectively maintain the stability of the inner core between the first and second side heads during the flow of pressurized liquid, thereby avoiding gaps between the first and second side heads and the inner core, preventing pressurized liquid from seeping out of the gaps, and separating the first and second side heads and the inner core by the tension of the pressurized liquid itself.
