Description

Technical Field

[0001] This utility model relates to the field of thermal insulation sleeve technology, and in particular to a detachable rigid thermal insulation sleeve that is easy to fasten. Background Technology

[0002] Aerogel composites possess low density and thermal conductivity while exhibiting good structural strength, making them a novel type of insulation material with excellent thermal insulation properties. Aerogel composites and stainless steel can be custom-processed into various shapes and specifications of molded insulation shells, suitable for various straight pipes, elbows, tees, reducers, flanges, partitions, insulated pipe supports, etc., to provide a variety of high-efficiency, easy-to-assemble and disassemble, and durable insulation products.

[0003] Currently, regardless of whether it's a single-layer or double-layer rigid detachable insulation sleeve, during actual construction and installation, the large size of the outer layer of the inner soft aerogel insulation sleeve makes it difficult to close the rigid stainless steel insulation sleeve after insertion. This often requires multiple people to press, squeeze, and pull the latches for installation, which is time-consuming and labor-intensive. Even worse, in some cases, the rigid insulation sleeve still cannot be closed successfully, necessitating the removal of the inner soft aerogel insulation sleeve and re-cutting and re-adjusting its size to fit the outer rigid stainless steel insulation sleeve. This inflexible design also carries the risk of sudden breakage after a forced connection, making subsequent opening, repair, or emergency repairs inconvenient.

[0004] Therefore, there is an urgent need to develop a flexible, adjustable, and easy-to-fasten detachable rigid insulation sleeve to facilitate the smooth fastening of rigid insulation sleeve products. Utility Model Content

[0005] The purpose of this invention is to provide a detachable rigid insulation sleeve that is easy to fasten, so as to facilitate the embedding of a soft aerogel insulation sleeve into a rigid outer shell and achieve smooth fastening of the rigid insulation sleeve product.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A removable rigid thermal insulation sleeve that is easy to fasten includes a first rigid outer shell and a second rigid outer shell that are detachably connected. A soft aerogel thermal insulation sleeve is provided inside each of the two rigid outer shells, and several locking components are provided at the joint of the two rigid outer shells.

[0008] The locking assembly includes a latch fixedly disposed on the first rigid housing, and an adjustable latch ring movably disposed on the second rigid housing and capable of being attached to the latch.

[0009] The adjustable loop includes a first loop and a second loop that is detachably connected to the first loop.

[0010] Furthermore, both the first and second rigid shells are semi-circular ring structures, and the two can be spliced ​​together to form a complete circular ring structure.

[0011] Furthermore, at least one locking assembly is provided at the joint between the first and second rigid shells on both sides.

[0012] Furthermore, a mating layer is provided at the joint between the first rigid shell and the second rigid shell, and the edge of the mating layer is located on either of the rigid shells.

[0013] Furthermore, the buckle includes a buckle body and an arc-shaped hook structure integrally formed with the buckle body.

[0014] Furthermore, a horizontally arranged threaded rod is connected to one side of the second lap ring, and a threaded hole is provided on the first lap ring that can be threadedly engaged with the threaded rod.

[0015] Furthermore, both the first and second loops can be attached to the buckle.

[0016] Furthermore, the second rigid housing is provided with a rotating assembly, and the first loop of the adjustable loop is connected to the rotating assembly.

[0017] Furthermore, the rotating assembly includes a rotating support base and a rotating shaft disposed on the rotating support base, with a return spring wound around the rotating shaft and a connecting plate rotatably mounted thereon.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] Example 1:

[0042] A removable rigid insulation sleeve that is easy to fasten, such as Figure 1-2 As shown, it includes a first rigid shell 1 and a second rigid shell 2 that can be detachably connected. Both rigid shells are provided with soft aerogel insulation sleeves 3, and the joint between the two rigid shells is provided with several locking components 4.

[0043] The locking assembly 4 in this embodiment includes a latch 41 fixedly disposed on the first rigid housing 1, and an adjustable latch 42 movably disposed on the second rigid housing 2 and capable of being hooked onto the latch 41. The adjustable latch 42 includes a first latch 421 and a second latch 422 detachably connected to the first latch 421.

[0044] In this embodiment, the detachable rigid insulation sleeve embeds the soft aerogel insulation sleeve 3 into the first rigid outer shell 1 and the second rigid outer shell 2, and wraps the first rigid outer shell 1 and the second rigid outer shell 2 around the pipe or other equipment to be insulated. Finally, the first rigid outer shell 1 and the second rigid outer shell 2 are fastened and locked by the locking assembly 4.

[0045] If the actual size of the soft aerogel insulation sleeve 3 is within the normal range, the first rigid outer shell 1 and the second rigid outer shell 2 will align well. Locking can be achieved simply by attaching the first latch 421 to the buckle 41, thus enabling the soft aerogel insulation sleeve 3 to be inserted and the first rigid outer shell 1 and the second rigid outer shell 2 to be stably joined. If the actual size of the soft aerogel insulation sleeve 3 exceeds the normal range, making normal closure difficult, the second latch 422 can be connected to the first latch 421 and then attached to the buckle 41. The adjustable length of the second latch 422 extends the overlap range of the first latch 421, allowing the soft aerogel insulation sleeve 3, which exceeds the normal range, to be inserted into the first rigid outer shell 1 and the second rigid outer shell 2, and the two rigid outer shells can be joined and locked effortlessly.

[0046] Example 2:

[0047] A removable rigid thermal insulation sleeve that is easy to fasten includes a first rigid outer shell 1 and a second rigid outer shell 2 that are detachably connected. A soft aerogel thermal insulation sleeve 3 is provided inside each of the two rigid outer shells, and a number of locking components 4 are provided at the joint of the two rigid outer shells.

[0048] The difference from Embodiment 1 is that in this embodiment, both the first rigid outer shell 1 and the second rigid outer shell 2 are made of stainless steel and are both semi-circular ring structures. The two rigid outer shells can be spliced ​​into a complete circular structure, and both ends of the first rigid outer shell 1 and the second rigid outer shell 2 need to be spliced ​​and locked and fixed by the locking assembly 4. A mating layer 5 is provided at both sides of the splicing area of ​​the first rigid outer shell 1 and the second rigid outer shell 2. The edge of the mating layer 5 can be located on either rigid outer shell. The two semi-circular ring-shaped rigid outer shells are effectively spliced ​​after alignment. At least one locking assembly 4 is provided at both sides of the splicing area of ​​the first rigid outer shell 1 and the second rigid outer shell 2 to ensure a stable splicing on both sides of the first rigid outer shell 1 and the second rigid outer shell 2. In this embodiment, two locking assemblies 4 are provided at each side of the splicing area to improve the overall stability after the rigid insulation sleeve is fastened.

[0049] Example 3:

[0050] A removable rigid thermal insulation sleeve that is easy to fasten includes a first rigid outer shell 1 and a second rigid outer shell 2 that are detachably connected. A soft aerogel thermal insulation sleeve 3 is provided inside each of the two rigid outer shells, and a number of locking components 4 are provided at the joint of the two rigid outer shells.

[0051] like Figure 3-6As shown, the locking assembly 4 of this embodiment includes a latch 41 fixedly mounted on the first rigid housing 1, and an adjustable hook 42 movably mounted on the second rigid housing 2 and capable of being hooked onto the latch 41. The latch 41 includes a latch body 411 and an arc-shaped hook structure 412 integrally formed with the latch body 411. The adjustable hook 42 includes a first hook 421 and a second hook 422 detachably connected to the first hook 421. Both the first hook 421 and the second hook 422 can be hooked onto the latch 41 to meet the hooking requirements of the hook and latch 41 under different conditions. A horizontally arranged threaded rod 423 is connected to one side of the second hook 422, and a threaded hole 424 is provided on the first hook 421 that can be threadedly engaged with the threaded rod 423.

[0052] In this embodiment, the second rigid outer shell 2 is provided with a rotating assembly 6. The rotating assembly 6 specifically includes a rotating support 61 and a rotating shaft 62 disposed on the rotating support 61. A return spring 63 is wound around the rotating shaft 62 and a connecting plate 64 is rotatably mounted thereon. The first loop 421 of the adjustable loop 42 is inserted into the connecting plate 64 but is not fixedly connected, retaining a certain degree of rotational freedom. The connecting plate 64 is provided with a fastening groove 641, and a fastening seat 7 that can cooperate with the fastening groove 641 is fixedly provided on the second rigid outer shell 2.

[0053] Because the soft aerogel insulation sleeve 3 may have dimensional deviations or excess fabric at the corners, it cannot be easily fastened and locked after being stuffed into the outer rigid shell, often requiring rework for correction. Therefore, in this embodiment, the detachable rigid insulation sleeve can be selected according to the actual size of the soft aerogel insulation sleeve 3, as follows:

[0054] If the actual size of the soft aerogel insulation sleeve 3 is within the normal range, and the first rigid outer shell 1 and the second rigid outer shell 2 are properly aligned, the second latch 422 can be rotated and unscrewed. Then, the connecting plate 64 can be moved to hook the first latch 421 onto the buckle 41. Subsequently, the connecting plate 64 is moved in the opposite direction until the fastening groove 641 on the connecting plate 64 engages with the fastening seat 7. Other locking components 4 are fixed according to the above operation, thereby achieving the covering of the soft aerogel insulation sleeve 3 and the stable splicing of the first rigid outer shell 1 and the second rigid outer shell 2.

[0055] If the actual size of the soft aerogel insulation sleeve 3 exceeds the normal range, making normal closure difficult, the second clasp 422 can be screwed in via the threaded rod 423. Adjust the second clasp 422 until it can be easily hooked onto the latch 41. Then, reverse the movement of the connecting plate 64 until the latching groove 641 on the connecting plate 64 engages with the latching seat 7. The helical design of the thread allows for a certain degree of elastic deformation under axial force, thereby absorbing and dispersing the axial force to effectively prevent breakage or damage. Furthermore, the thread profile design allows the thread to generate sufficient friction under force, effectively preventing loosening or detachment and ensuring the stability and reliability of the connection. The adjustable length of the second clasp 422 extends the overlap range of the first clasp 421, allowing the soft aerogel insulation sleeve 3, which exceeds the normal range, to be inserted into the first rigid outer shell 1 and the second rigid outer shell 2, and the two rigid shells can be spliced ​​and locked together effortlessly.

[0056] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
