In order to better fit the cylindrical shape of the pipe body 1, the limit sleeve 1 31 and the limit sleeve 2 32 are both semi-circular ring-shaped. The limit sleeve 1 31 and the limit sleeve 2 32 can be spliced ​​into a circle. One end of the limit sleeve 1 31 and the limit sleeve 2 32 are hingedly installed with each other. The one side surface of the limit sleeve 1 31 and the limit sleeve 2 32 are respectively connected with a connecting block 1 33 and a connecting block 2 34, and the connecting block 1 33 and the connecting block 2 34 are locked with each other through a locking assembly 4. This structure can keep the pipe body 1 warm, making the pipe body 1 more frost-proof, and can reduce the internal temperature loss of the pipe body 1 in winter, thereby reducing the possibility of the pipe in the pipe body 1 being solidified, greatly increasing the practicality of the device.

[0030] It should be noted that the thermal insulation layer 21 may be made of thermal insulation cotton commonly used to wrap water pipes, and the thermal insulation layer 22 may be made of aluminum foil, which can play a certain role in thermal insulation.

[0031] As an implementation method in this embodiment, Figure 4As shown, the locking assembly 4 includes a slide groove 41, a slot 45 and a limit assembly 5. The slide groove 41 and the slot 45 are respectively arranged at the bottom end of the connecting block 34 and the top end of the connecting block 33.

[0032] As an implementation method in this embodiment, Figure 5 and Figure 6 As shown, the limiting assembly 5 includes a second slide groove 51 and a limiting groove 54.

Figure 6 As shown, the outer diameter of the end of the slide rod 53 is matched with the inner diameter of the limiting groove 54, so that the limiting of the shifting rod 48 is more stable.

[0033] Working principle: If the pipe body 1 needs to be insulated, it is only necessary to wrap the thermal insulation layer 21 and the thermal insulation layer 22 on the surface of the pipe body 1 in sequence, and then the two sets of limit sleeves 1 31 and limit sleeves 2 32 are respectively sleeved on both sides of the surface of the thermal insulation layer 22, and then the connecting block 1 33 and the connecting block 2 34 are closed, so that the card block 44 is aligned with the slot 45 and inserted, and then the card block 44 is pushed by squeezing, and the card block 44 drives the slider 43 to slide in the slide groove 1 41 to compress the spring 1 42, until the card block 44 is completely inserted into the slot 45, and then the slider 43 is pushed by the restoring force of the spring 1 42 to drive the card block 44 to be inserted into the card groove 46 to complete the locking, so that the thermal insulation layer 21 and the thermal insulation layer 22 can be fixedly wrapped on the surface of the pipe body 1 for heat preservation;

[0034] In addition, if the thermal insulation layer 21 or the thermal insulation layer 22 needs to be replaced, it is only necessary to move the lever 1 48 to slide in the guide opening 47, and the lever 1 48 drives the slider 43 to slide in the slide groove 1 41 to compress the spring 1 42, and the slider 43 drives the block 44 to move. At this time, the lever 1 48 will also squeeze and push the slide rod 53, and push the slide rod 53 into the slide groove 2 51 to compress the spring 2 52 until the block 44 moves from the card groove 46 to the slot 45, and the slide rod 53 corresponds to the limiting slot 54, and the slide rod 53 can be pushed and inserted into the limiting slot 54 by the restoring force of the spring 2 52, so as to limit the lever 1 48, so that the block 44 can be kept in the slot 4 5, according to the above operation, the locks of the two groups of connecting blocks 1 33 and connecting blocks 2 34 are unlocked in turn, so that one group of limiting sleeves 1 31 is rotated to open, and the other group of limiting sleeves 1 31 is also opened together through the connecting rod 35, which is more convenient. After removing the limiting sleeves 1 31 and the limiting sleeves 2 32, the thermal insulation layer 21 or the thermal insulation layer 22 can be replaced. If the limiting sleeves 1 31 and the limiting sleeves 2 32 need to be used again for fixing, it is only necessary to move the lever 2 55 to drive the sliding rod 53 to slide in the sliding groove 2 51 to compress the spring 2 52 until the sliding rod 53 is pulled out of the limiting groove 54, and the limiting of the lever 1 48 is unlocked, which greatly increases the practicality of the device.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
