Description

Technical Field

[0001] This utility model relates to the field of pipe insulation jacket technology, and in particular to a self-locking quick-installation pipe insulation jacket. Background Technology

[0002] In numerous fields such as industrial production, building heating, municipal pipe networks, and energy transmission, pipelines serve as the core carriers for fluid (including liquids and gases), and the stability of their operating temperature directly impacts production efficiency, energy utilization, and system safety and reliability. To prevent excessive heat exchange between the transported medium and the external environment, which could lead to energy waste or equipment failures and pipeline freezing due to abnormal temperature fluctuations, effective pipeline insulation has become an indispensable and crucial step in these fields. Currently, common pipeline insulation methods on the market mainly include two types: traditional on-site wrapping insulation and prefabricated insulation structures.

[0003] In the existing technology, when installing pipe insulation jackets, because there is no self-locking function, the operator must accurately fix all external connectors one by one. It is necessary to ensure the tightness of each connector and the alignment of the jacket splices. Especially in high-altitude operations, densely arranged pipelines, or confined spaces, the operation difficulty is greatly increased. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-locking quick-installation pipe insulation jacket, which solves the problem of the difficulty of operation for operators when installing pipe insulation jackets due to the lack of self-locking function.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A self-locking quick-installing pipe insulation jacket includes a first half-jacket and a second half-jacket for clamping a pipe. Both the first and second half-jackets contain insulation cotton for pipe insulation. The self-locking quick-installing pipe insulation jacket also includes: The self-locking mechanism includes a hinge block that is hinged to the second half-clamp along the length of the first half-clamp and close to it. A movable plate and a self-locking plate installed along the length of the movable plate are movably disposed inside the second half-clamp. A latch and a locking hole for locking the self-locking plate are installed on the first half-clamp opposite to the hinge block. A cavity for accommodating the self-locking plate is provided inside the second half-clamp. A return spring connected to one end of the self-locking plate is installed inside the cavity.

[0006] As a preferred technical solution of this application, the first half-jacket and the second half-jacket are semi-circular in shape with the same size.

[0007] As a preferred technical solution of this application, the latch has a first arc surface on one end near the self-locking plate, and the self-locking plate has a second arc surface corresponding to the first arc surface.

[0008] As a preferred technical solution of this application, the self-locking plate is L-shaped, and the second half-sleeve has a slot on the side corresponding to the self-locking plate for the buckle to be inserted.

[0009] As a preferred technical solution of this application, a connecting plate and an unlocking plate fixed on the top of the moving plate for dragging the moving plate are fixedly provided on the top of the connecting plate.

[0010] As a preferred technical solution of this application, the unlocking plate is fixedly provided with a thumb plate for the operator to push, and the second half-clamp is provided with a limiting hole for the thumb plate to move.

[0011] As a preferred technical solution of this application, the thumb plate is provided with resistance stripes, which have an anti-slip function.

[0012] As a preferred technical solution of this application, the movable plate is provided with a circular groove at one end near the reset spring, and the circular groove is adapted to accommodate the reset spring.

[0013] The self-locking quick-installation pipe insulation jacket described in this utility model has the following beneficial effects: 1. This solution guides the second half-sleeve to make arc-shaped movements through the hinge block. In conjunction with the arc-shaped pressing linkage between the latch and the self-locking plate, after the latch is inserted into the cavity, the precise cooperation between the first arc surface and the second arc surface of the self-locking plate generates a pressing friction force. Combined with the energy storage and release characteristics of the return spring, the self-locking plate is accurately locked into the lock hole, thereby achieving the effect of quick self-locking of the first half-sleeve and the second half-sleeve. 2. In this solution, the thumb plate drives the unlocking plate to move through the connecting plate. The moving plate compresses the reset spring and simultaneously drives the self-locking plate out of the lock hole. The operation is intuitive and labor-saving, and the disassembly time is significantly shortened. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings. This detailed description is an illustration of exemplary embodiments of the present invention, including various details of these embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0019] As described in the background art, in the prior art, when installing pipe insulation jackets, because there is no self-locking function, the operator needs to accurately fix all external connectors one by one, ensuring both the tightness of each connector and the alignment of the jacket splices. This greatly increases the difficulty of operation, especially in high-altitude operations, densely arranged pipelines, or confined spaces.

[0020] To solve this technical problem, this utility model provides a self-locking quick-installation pipe insulation jacket, which is applied to provide a self-locking quick-installation pipe insulation jacket that can be quickly installed.

[0021] Example 1, specifically, refer to Figures 1-5 As shown, a self-locking quick-installing pipe insulation jacket includes a first half-jacket 1 and a second half-jacket 2 for clamping the pipe. Both the first half-jacket 1 and the second half-jacket 2 are provided with insulation cotton 102 to insulate the pipe. The self-locking quick-installing pipe insulation jacket also includes: The self-locking mechanism includes a hinge block 101 that is hinged to the second half-clamp 2 along the length of the first half-clamp 1 and close to it. The second half-clamp 2 has a movable plate 301 and a self-locking plate 302 installed along the length of the movable plate 301. The first half-clamp 1 has a latch 103 installed opposite to the hinge block 101 and a locking hole 104 opened on the latch 103 for locking the self-locking plate 302. The second half-clamp 2 has a cavity 3 for accommodating the self-locking plate 302. A return spring 304 connected to one end of the self-locking plate 302 is installed in the cavity 3. The first half-clamp 1 and the second half-clamp 2 are semi-circular in shape with the same size. The movable plate 301 has a circular groove at one end near the return spring 304, which is adapted to accommodate the return spring 304.

[0022] The following is a supplementary explanation based on the above structure: the insulation cotton 102 is made of glass wool and is bonded to the first half-jacket 1 and the second half-jacket 2 with resin glue; the second half-jacket 2 is guided to make arc-shaped movement by the hinge block 101, and the automatic alignment and fastening of the two half-jackets are achieved by the arc-shaped compression linkage between the latch 103 and the self-locking plate 302. After the latch 103 is inserted into the cavity 3, the compression friction force is generated by the precise cooperation between the first arc surface and the second arc surface 303 of the self-locking plate 302. Combined with the energy storage and release characteristics of the return spring 304, the self-locking plate 302 is accurately locked into the lock hole 104, thereby achieving the self-locking effect; the setting of the circular groove makes the inner wall of the circular groove fit tightly with the outer diameter of the return spring 304, forcibly constraining the spring to extend and retract along the predetermined axis, avoiding the skewing or jamming caused by uneven force. Compared with the traditional flat-bottom installation, which is prone to lateral displacement due to vibration, the circular groove forms an annular limiting surface, fundamentally eliminating the possibility of the spring leaving the preset working path.

[0023] like Figure 3 and Figure 5 As shown, further in this embodiment, the latch 103 has a first arc surface on one end near the self-locking plate 302, and the self-locking plate 302 has a second arc surface 303 corresponding to the first arc surface. The self-locking plate 302 is L-shaped. The second half-clamp 2 has a slot for the latch 103 to be inserted on the side corresponding to the self-locking plate 302. The arrangement of the first arc surface and the second arc surface 303 makes it easy to squeeze when the latch 103 contacts the self-locking plate 302, and there will be no jamming. When the self-locking plate 302 is located on one side of the latch 103, the pressure released by the return spring 304 causes the self-locking plate 302 to be inserted into the lock hole 104, thereby achieving the self-locking effect.

[0024] Example 2, specifically, refer to Figures 3-5As shown, a connecting plate 4 and an unlocking plate 401 fixed on the top of the movable plate 301 are provided for dragging the movable plate 301. A thumb plate 402 for the operator to push is fixed on the unlocking plate 401. A limiting hole 404 for the thumb plate 402 to move is provided on the second half-clamp 2.

[0025] The following is a supplementary explanation based on the above structure: The push of the thumb plate 402 drives the unlocking plate 401 to move. The unlocking plate 401 drives the moving plate 301 to move through the connecting plate 4 and compresses the return spring 304. During this process, the moving plate 301 will drive the self-locking plate 302 to move. When the thumb plate 402 is in contact with the wall of the limiting hole, the self-locking plate 302 will disengage from the locking hole 104 of the latch 103, thereby achieving the effect of quick disassembly. The setting of the limiting hole means that the thumb plate 402 must be in contact with the wall of the limiting hole to achieve disassembly, avoiding accidental loosening caused by non-human operation.

[0026] like Figure 4 As shown, further, in this embodiment, the thumb plate 402 is provided with resistance stripes 403, which have an anti-slip function. The setting of resistance stripes 403 increases the roughness of the thumb plate 402, allowing the operator to clearly perceive the displacement of the thumb plate 402.

[0027] The implementation principle of a self-locking quick-installation pipe insulation jacket in this application embodiment is as follows: During use, the first half-jacket is attached to the pipe, and then the second half-jacket 2 is moved in an arc shape with the hinge block 101 as the fulcrum, so that the second half-jacket 2 and the first half-jacket 1 are symmetrically attached to the pipe. Simultaneously, the latch 103 on the first half-jacket 1 enters the cavity 3 through the slot on the second half-jacket 2. The latch 103 utilizes the first arc surface and the second arc surface 303 of the self-locking plate 302 to press against the pipe, causing the self-locking plate 302 to drive the moving plate 301 to move within the cavity 3 and compress it. When the self-locking plate 302 is located on one side of the latch 103, the return spring 304 releases the elastic force compressed by the moving plate 301, causing the moving plate 301 to move and reset. Then, under the action of the moving plate 301, the L-shaped self-locking plate 302 is inserted into the lock hole 104. Thus, by utilizing the cooperation between the self-locking plate 302 and the latch 103, the effect of quick self-locking installation between the first half-jacket 1 and the second half-jacket 2 is achieved. During use, the insulation cotton 102 located in the first half-jacket 1 and the second half-jacket 2 is used to complete the insulation of the pipeline.

[0028] When it is necessary to disassemble the first half-clamp 1 and the second half-clamp 2, the operator pushes the thumb plate 402 to move the unlocking plate 401. The unlocking plate 401 moves the moving plate 301 through the connecting plate 4 and compresses the return spring 304. During this process, the moving plate 301 moves the self-locking plate 302. When the thumb plate 402 is in contact with the wall of the limiting hole, the self-locking plate 302 will disengage from the locking hole 104 of the latch 103. The first half-clamp 1 can then be moved out of the cavity 3 of the second half-clamp 2 along with the latch 103. The first half-clamp 1 and the second half-clamp 2 can then be removed from the pipe, thus quickly completing the disassembly.

[0029] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.
