Technical Field

[0001] The utility model relates to the technical field of ground source heat pumps, in particular to an inner pipe limiting clamp for a ground source heat pump which is easy to disassemble and assemble. Background Art

[0002] During the installation of the common ground source heat pumps in existing life, it is usually necessary to install an inner pipe of the running pipe to facilitate the normal use of the ground source heat pump. However, during the connection of the common ground source heat pump inner pipes, different lengths of inner pipes are required due to different environmental sites. When connecting the common inner pipes, most of them use more bolts to connect the inner pipe connection ports. This method is very likely to cause the connection and fixation of the inner pipe to take a long time due to the need to use more bolts. If the bolts are not firmly fixed during the bolt fixing process, it is very easy to cause the connection port of the inner pipe to have unstable linear limit, which is very easy to cause the inner pipe to detach, resulting in the connection between the inner pipes not having good stable fixing measures, resulting in the connection port of the inner pipe being easily detached due to the loosening of the inner pipe, which seriously affects the limit fixing stability measures of the connection between the inner pipes. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art. Most of the common inner pipe connection ports are fixed with a large number of bolts, which easily causes unstable connection of the inner pipes and seriously affects the limiting and fixing measures at the connection ports between the inner pipes. The utility model provides an inner pipe limiting clamp for a ground source heat pump that is easy to disassemble and assemble.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an inner tube limit clamp for a ground source heat pump that is easy to disassemble and assemble, comprising: a fixed frame, a fixing mechanism is provided on one side of the fixed frame, an anti-slip pad is adhered to the inner wall of the fixed frame, the fixing mechanism comprises a fixed block provided on one side of the fixed frame, a rotating block is provided on one side of the fixed block, a rotating rod is fixedly connected to one side of the rotating block, the outer surface of the rotating rod is movably connected to the limiting plate through a bearing, one end of the rotating rod is fixedly connected to a threaded rod, the interior of the fixed block is fixedly connected to the limiting rod, and the outer surface of the limiting rod is sleeved with a tension spring.

[0005] As a preferred embodiment, a fixing groove adapted to the fixing frame is formed on one side of the fixing block.

[0006] As a preferred embodiment, one end of the rotating rod slides through one side of the fixed block, and a first limiting groove adapted to the limiting plate is provided inside the fixed block.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: an inner pipe limit clamp for a ground source heat pump that is easy to disassemble and assemble, comprising: a fixing frame 1, a fixing mechanism 2 is provided on one side of the fixing frame 1, and an anti-slip pad 3 is adhered to the inner wall of the fixing frame 1, the fixing mechanism 2 comprises a fixing block 21 provided on one side of the fixing frame 1, and a fixing groove adapted to the fixing frame 1 is provided on one side of the fixing block 21. By providing the fixing groove, the fixing block 21 can be sleeved on the outer surface of the fixing frame 1, and a rotating block 22 is provided on one side of the fixing block 21. A rotating rod 23 is fixedly connected to one side of the rotating block 22, and one end of the rotating rod 23 slides through one side of the fixing block 21. A first limiting groove adapted to the limiting plate 25 is provided inside the fixing block 21. By providing the first limiting groove, the limiting plate 25 can move normally inside the fixing block 21, and the outer surface of the rotating rod 23 is movably sleeved on the limiting plate 25 through a bearing. The limit rod 27 is adapted to fit the limit rod 27 on one side of the plate 25. By providing the limit hole, the limit plate 25 can maintain a good moving limit feature with the help of the limit rod 27 during the movement. One end of the rotating rod 23 is fixedly connected to the threaded rod 26, and one end of the threaded rod 26 slides through the other side of the inner wall of the first limit groove inside the fixed block 21. By setting the threaded rod 26 to slide through the fixed block 21, the threaded rod 26 can be normally moved out of the inside of the fixed block 21. The inside of the fixed block 21 is fixedly connected to the limit rod 27, and the outer surface of the limit rod 27 is sleeved with a tension spring 28. One end of the tension spring 28 is welded to one side of the inner wall of the first limit groove inside the fixed block 21, and the other end of the tension spring 28 is welded to one side of the limit plate 25. By setting the tension spring 28, the tension spring 28 provides sufficient tension, so that the limit plate 25 can actively move with the help of the tension of the tension spring 28 after moving.

[0023] Example 2

[0024] like Figure 2 and Figure 4The locking mechanism 242 is actuated by a spring 243 which is provided on the outer surface of the locking mechanism 241 so as to allow the locking mechanism 242 to be locked in the locking position.

[0025] Working principle:

[0026] like Figure 1-4As shown, during installation, the fixed frame 1 is sleeved onto the outer surface of the inner tube and the fixed frame 1 is kept fixed. When the fixed frame 1 is sleeved onto the inner tube surface and fixed, the fixed frame 1 is fixed using the fixing block 21. The fixing block 21 is sleeved onto one side of the fixed frame 1. When the fixing block 21 is sleeved onto the fixed frame 1, the baffle 244 on one side of the fixed frame 1 is pulled to move. During the movement of the baffle 244, the positioning rod 241 is moved. During the movement of the positioning rod 241, the limiting plate 242 is moved inside the fixed frame 1. The spring 243 is affected by the force of the movement of the limiting plate 242, and its shape gradually changes until the baffle 244 is pulled to move and cannot move further. The positioning rod 241 is completely moved into the fixed frame 1 and keeps the baffle 244 in the position after being pulled. After the fixed block 21 is completely sheathed on the outer surface of one side of the fixed frame 1, the retaining plate 244 is released, and the spring 243 is no longer affected by the force and gradually restores its shape. It actively drives the limit plate 242 to move, and the positioning rod 241 gradually moves out of the interior of the fixed frame 1 and gradually inserts into the interior of the fixed block 21 as the limit plate 242 moves, until the positioning rod 241 is completely inserted into the interior of the fixed block 21. Slowly push the rotating block 22 to move, and the rotating block 22 drives the rotating rod 23 to move. The limiting plate 25 gradually slides on the outer surface of the limiting rod 27 following the movement of the rotating rod 23. The tension spring 28 is affected by the force of the movement of the limiting plate 25 and gradually changes its shape. As the rotating block 22 and the rotating rod 23 move, the threaded rod 26 gradually moves out of the interior of the fixed block 21 and contacts the positioning rod 241. After pushing the rotating block 22 to move until it can no longer move, keep the position of the rotating block 22 after it is moved and slowly rotate the rotating block 22. During the rotation of the rotating block 22, the rotating rod 23 is driven to rotate, and the threaded rod 26 follows and is gradually inserted into the interior of the positioning rod 241 until the rotating block 22 can no longer rotate, that is, the fixed frame 1 is sleeved on the outer surface of the inner tube and completes the limit fixation of the inner tube.
