Abstract

This utility model discloses an integrated clamp for a PCW circulation system, comprising an anti-pull-out outer sleeve, inner core, and hose, relating to the field of pipeline connection technology. The integrated clamp for a PCW circulation system includes: an outer sleeve body; and an extension sleeve formed at one end of the outer sleeve body, wherein the extension sleeve has the same axis as the outer sleeve body, and the radius of the extension sleeve is smaller than the radius of the outer sleeve body; both the outer sleeve body and the extension sleeve can be compressed by an extruder. This integrated clamp for a PCW circulation system, by setting the extension sleeve, allows the outer sleeve to be pressed into the groove on the inner core body through a secondary pressing process, thereby ensuring a tight fit between the outer sleeve body and the inner core body. When the integrated clamp is subjected to external tensile force, the extension sleeve is less likely to deform, thus improving the anti-pull-out effect of the integrated clamp.

Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to an anti-pull-out outer jacket, inner core, and hose integral clamp for PCW circulation systems. Background Technology

[0002] The PCW (Process Cooling Water) circulation system mainly consists of a water tank, circulating pump, filter, plate heat exchanger, electrical control system, and water replenishment and pressure stabilization device. It is widely used in the semiconductor and microelectronics industries to provide indirect cooling for critical process equipment. The cooling water process requires the use of hoses and hose connectors for connection. The hose clamp is an important component, which mainly consists of an outer jacket and an inner core.

[0003] Currently, most of the outer sleeves used in integral hose clamps are formed by stamping. This results in the arc angle at the connection between the clamping platform and the sleeve body being larger on the outside and smaller on the inside. When the hose is pulled by the outside, the clamping platform is easily deformed, which leads to an increase in the gap between the clamping platform and the inner core on the outer sleeve and causes it to fall off. This makes the integral hose clamp have poor anti-pull-out effect. Utility Model Content

[0004] The purpose of this invention is to provide an integrated clamp for an anti-pull-out outer sleeve, inner core, and hose for a PCW circulation system, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-pull-out jacket for a PCW circulation system, comprising: a jacket body; an extension sleeve formed at one end of the jacket body, wherein the extension sleeve has the same axis as the jacket body and the radius of the extension sleeve is smaller than the radius of the jacket body; both the jacket body and the extension sleeve can be compressed by an extruder.

[0006] Preferably, it further includes: a plurality of grooves formed on the surface of the outer cover body, the grooves extending into the interior of the outer cover body to form protrusions, and the plurality of grooves being evenly distributed along the surface of the outer cover body.

[0007] Preferably, the groove has a trapezoidal and / or semi-circular cross-sectional shape.

[0008] An inner core includes: an inner core body; a slot formed on the inner core body, the slot engaging with an extension sleeve to fix the position of an outer sleeve body; a plurality of grooves formed on the inner core body, the grooves being evenly distributed along the axial direction of the inner core body; and a plurality of mating surfaces formed between adjacent grooves.

[0009] Preferably, it further includes: an extension surface, formed at the mating end of the inner core body, wherein the axial angle between the extension surface and the inner core body is 20°.

[0010] Preferably, it further includes: a ring-shaped end, fixedly disposed at the top of the inner core body; and a fastener, movably disposed on the inner core body for connection with other components.

[0011] The hose integral clamp includes: an anti-pull-out outer sleeve for PCW circulation systems provided by any of the above and an inner core provided by any of the above.

[0012] This utility model provides an integrated clamp for a PCW circulation system, comprising an anti-pull-out outer sleeve, inner core, and hose, which has the following advantages:

[0013] (1) By setting an extension sleeve, the outer sleeve is pressed into the groove on the inner core body through a secondary pressing method, so that the outer sleeve body is tightly fitted with the inner core body. When the hose clamp is subjected to external tension, the extension sleeve body is difficult to deform, thereby improving the pull-out resistance of the hose clamp.

[0014] (2) By setting a groove on the outer surface of the outer casing and extending the groove into the inner part of the outer casing to form a protrusion, the present invention can apply additional pressure to the hose during pressing, so that the hose and the hose clamp fit more tightly, thereby improving the reliability of the overall connection.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1: As Figure 1-4 As shown, an embodiment of this utility model provides an anti-pull-out jacket for a PCW circulation system, comprising: an jacket body 1; and an extension sleeve 2 formed at one end of the jacket body 1, wherein the extension sleeve 2 has the same axis as the jacket body 1 and the radius of the extension sleeve 2 is smaller than the radius of the jacket body 1. Both the jacket body 1 and the extension sleeve 2 can be squeezed by an extruder. Through the setting of the extension sleeve 2, it can be inserted into the slot 5 on the inner core body 4 by the squeezing effect of the extruder. When the hose clamp is dragged by the outside, the force-bearing part changes from the original clamping platform to the extension sleeve 2, so that the hose clamp can withstand a large pulling force and the jacket body 1 is not easily deformed, thereby improving the overall anti-pull-out effect of the hose clamp.

[0025] Reference Figure 2 and Figure 3 In some embodiments, a plurality of grooves 3 are formed on the surface of the outer body 1, and the grooves 3 extend into the interior of the outer body 1 to form protrusions. The plurality of grooves 3 are evenly distributed along the surface of the outer body 1. By setting the grooves 3, protrusions can be formed inside the outer body 1. Then, under the extrusion action of the extruder, the protrusions can cooperate with the toothed grooves 7 on the inner core body 4 to tightly fix the hose inside the hose overall clamp, thereby improving the overall connection strength.

[0026] Reference Figure 3 In other embodiments, the groove 3 has a trapezoidal and / or semi-circular cross-sectional shape, which can apply additional force to the hose and increase the fit strength. The trapezoidal and semi-circular design can reduce the shear force on the hose during the extrusion process and prevent the hose from breaking during the connection process.

[0027] Example 2: Refer to Figure 5 and Figure 6 As shown, an embodiment of this utility model provides an inner core, including: an inner core body 4; a slot 5 formed on the inner core body 4, the slot 5 engaging with an extension sleeve 2 to fix the position of the outer body 1; a plurality of grooves 7 formed on the inner core body 4, the grooves 7 being evenly distributed along the axial direction of the inner core body 4; and a plurality of mating surfaces 8 formed between adjacent grooves 7. By setting the grooves 7, the hose and the inner core body 4 can be more tightly fitted during the pressing process, which improves the sealing performance and prevents detachment. The mating surfaces 8 can extend the included angle between the grooves 7, increase the force-bearing area of ​​the hose, and prevent damage to the hose during the compression process. The height of the mating surfaces 8 should be greater than 2mm.

[0028] In some embodiments, refer to Figure 5and Figure 7 The extension surface 9 is located at the docking end of the inner core body 4, and the axial angle between the extension surface 9 and the inner core body 4 is 20°; the ring end 6 is fixedly set at the top of the inner core body 4; the fastener 10 is movably set on the inner core body 4 for connecting with other components. The extension surface 9 makes it easier for the hose to enter the inner core body 4, improving the ease of installation. The ring end 6 can limit the fastener 10 to prevent it from falling off.

[0029] Example 3: Figure 6 and Figure 7 As shown, the embodiments of this utility model provide a hose integral clamp, including: an anti-pull-out outer sleeve provided in Embodiment 1 and an inner core provided in Embodiment 2.

[0030] The technical solution provided by this utility model is as follows: When connecting the hose and the hose connector, the matching hose is inserted into the gap between the inner core body 4 and the outer body 1. Then, the outer body 1 is squeezed into the inner core of the hose using a compression press. After the compression is completed, the extension sleeve 2 is squeezed again using a compression press so that the extension sleeve 2 enters the slot 5 of the inner core body 4, thereby completing the connection between the hose connector and the matching hose and making the connection between the hose connector and the matching hose more secure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
