[0019] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] The following will be combined with the instructions attached Figure 1-3 And specific implementation methods are used to describe the above technical solutions in detail:

[0021] The utility model provides a high and low temperature circulation device, comprising a base plate 1 and a circulation device body 2, a plurality of symmetrically arranged installation grooves 3 are provided at the lower end of the base plate 1, an electric telescopic rod 4 is fixedly connected in the installation groove 3, a moving component is provided at the lower end of the electric telescopic rod 4, a downwardly inclined slope 5 is provided on one side of the upper end of the base plate 1, an extension plate 6 is provided on one side of the slope 5 of the base plate 1, the lower surface of the extension plate 6 is in contact with the ground, a slope body 7 with the same inclination angle as the slope 5 is fixedly connected on one side of the extension plate 6, notches 8 with the same angle as the slope body 7 are provided on both sides of the lower end of the circulation device body 2, a positioning groove 9 is provided on the base plate 1, a side of the positioning groove 9 close to the slope 5 is chamfered, and its chamfer angle is the same as that of the slope 5, and a fixed component is provided on the base plate 1. When it is necessary to move the high and low temperature circulation device, the base plate 1 is controlled to move to the side of the circulation device body 2 so that the slope 7 can be inserted into the notch 8 at the lower end of the circulation device body 2, and then the circulation device body 2 is pushed toward the base plate 1. During this process, the circulation device body 2 slides on the slope 7, the extension plate 6, the slope 5 and the base plate 1 in turn until it moves into the positioning groove 9, and then it is fixed by a fixing component so that the circulation device body 2 can be fixed on the base plate 1. After the fixation is completed, the electric telescopic rod 4 is pushed outward, and under the relative force, the base plate 1 will gradually rise until the extension plate 6 and the slope 5 are separated from the ground, and then it can be moved by the moving component. After moving to the designated position, the electric telescopic push rod is retracted, so that the bottom plate 1 can be lowered until the extension plate 6 and the slope 7 are in contact with the ground. Then the fixing assembly no longer fixes the circulation device body 2, and then pushes the circulation device body 2 toward the slope 7. Since the positioning groove 9 is chamfered on the side close to the slope 5, the circulation device body 2 can be easily moved to the bottom plate 1, and then slides on the slope 5, the extension plate 6 and the slope 7 in turn until it moves to the ground. During the entire moving process, compared with lifting the high and low temperature circulation device for installation or disassembly, the push-slide method is obviously more time-saving and labor-saving, reduces work intensity, and reduces safety hazards.

[0022] In order to facilitate the movement of the circulation device body 2 into the installation groove 3, as a preferred solution, two symmetrically arranged grooves 10 are provided on the bottom plate 1, the ramp 5, the extension plate 6 and the ramp body 7. The grooves 10 are in a connected state as a whole. A plurality of rotating wheels 11 are rotatably connected in the grooves 10. The lower end of the circulation device body 2 is provided with a wheel groove 12 corresponding to the groove 10. When the ramp body 7 is inserted into the notch 8, the positions of the groove 10 and the wheel groove 12 correspond, so that the rotating wheel 11 is also in the wheel groove 12. In the subsequent pushing process, the circulation device body 2 can be pushed more labor-savingly by providing the rotating wheel 11.

[0023] For easy movement, as a preferred solution, a storage groove 13 is provided on the lower surface of the bottom plate 1, and the side walls of the storage groove 13 are slidably connected to the two sides of the extension plate 6. Before moving the entire device by the moving assembly, the extension plate 6 is pushed into the storage groove 13 for storage, which can save space and facilitate movement.

[0024] As a preferred solution, the fixing assembly includes a double-headed motor 14 fixedly connected to the base plate 1, and screw rods 15 are connected to both ends of the double-headed motor 14 respectively. The outer side of the screw rod 15 is threadedly connected to a moving rod 16 slidably connected to the base plate 1, and the upper end of the moving rod 16 is fixedly connected to a cross bar 17, and the end of the cross bar 17 is fixedly connected to a clamping plate 18, and the positioning groove 9 is provided between the two clamping plates 18. When the fixing assembly needs to fix the circulation device body 2, the double-headed motor 14 rotates to drive the screw rods 15 at both ends to rotate. Since the moving rods 16 are slidably connected to the base plate 1, the two moving rods 16 rotatably connected to the screw rods 15 can move toward the double-headed motor 14, thereby driving the cross bar 17 and the clamping plate 18 to move toward the circulation device body 2 until the clamping plate 18 can clamp and fix them. After moving to the specified position, the double-headed motor 14 reverses, so that the moving rod 16 drives the cross bar 17 and the clamping plate 18 to move away from the circulation device body 2. Preferably, the thread directions of the two screw rods 15 enable the moving rod 16 to complete the above-mentioned movement.

[0025] In order to reduce the impact of vibration during movement, as a preferred solution, a buffer assembly is provided on the opposite side of the two clamping plates 18, and the buffer assembly includes a sleeve 19 fixedly connected to the clamping plate 18, a slide bar 20 is slidably connected in the sleeve 19, and a buffer plate 21 is fixedly connected to the end of the slide bar 20. A spring 22 is connected between the buffer plate 21 and the sleeve 19 through a damper, and the spring 22 is sleeved on the outside of the slide bar 20. When the clamping plate 18 moves toward the circulation device body 2, the buffer plate 21 will first contact it. As the clamping plate 18 continues to move until the circulation device body 2 is fixed, the sleeve 19 will also move, thereby compressing the spring 22. When encountering vibration, the spring 22 can absorb part of it, thereby reducing the impact.

[0026] In order to enhance the buffering effect, as a preferred solution, the buffer plate 21 is a rubber plate, which not only improves the buffering effect, but also increases the friction to enhance the fixing effect, while also avoiding damage to the surface of the circulation device body 2.

[0027] In order to further enhance the buffering effect, as a preferred solution, the moving assembly includes a buffering structure and a moving wheel 23, the lower end of the electric telescopic rod 4 is connected to the buffering structure, and the lower side of the buffering structure is connected to the moving wheel 23. The buffering structure can absorb part of the vibration.

[0028] As a preferred solution, the buffer structure includes a support rod 24 fixedly connected to the electric telescopic rod 4, a rubber block 25 fixedly connected to the lower end of the support rod 24, a limit plate 26 fixedly connected to the lower end of the rubber block 25, and the lower side of the limit plate 26 is connected to the moving wheel 23. During movement, the rubber block 25 can absorb part of the vibration due to its elasticity.

[0029] Preferably, the high and low temperature circulation device and motor mentioned above are mature existing technologies, so their structure and principle will not be described here in detail. The specifications and models of the motor can be selected according to actual conditions. When the circuit is connected, it is connected to the municipal circuit by default.

[0030] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0031] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
