Description

Technical Field

[0001] This utility model relates to the field of finned evaporator technology, and in particular to a finned tube evaporator with a protective device. Background Technology

[0002] Finned tube evaporators are widely used in refrigeration and air conditioning systems to increase heat exchange area and improve heat exchange efficiency. To enhance their performance, the design of protective devices is particularly important, especially to prevent damage or corrosion to the evaporator fins and tubes from the external environment.

[0003] In the existing technology of finned tube evaporators with protective devices, most of the protective devices are fixed to the base, which has great limitations and is not convenient for protecting evaporators of different sizes. Utility Model Content

[0004] To at least partially solve the above-mentioned technical problems, this utility model provides a finned tube evaporator with a protective device.

[0005] This utility model is achieved using the following technical solution: a finned tube evaporator with a protective device, comprising a protective base, a T-shaped groove on the top of the protective base, a T-shaped connecting rod slidably connected to the inner wall of the T-shaped groove, front and rear protective plates fixedly connected to the surface of the T-shaped connecting rod, a bidirectional threaded rod threadedly connected to the inner wall of the T-shaped connecting rod, the outer wall of the bidirectional threaded rod rotatably connected to the inner wall of the protective base, the back of the bidirectional threaded rod penetrating through the inner wall of the protective base and extending therefrom, an adjustment groove on the back of the bidirectional threaded rod, an adjustment handle contacting the inner wall of the adjustment groove, a limit block contacting the inner wall of the adjustment groove, a limit hole on the back of the protective base, a limit rod fixedly connected to the surface of the limit block, and the outer wall of the limit rod contacting the inner wall of the limit hole.

[0006] As a further improvement to the above solution, four T-shaped connecting rods are provided, and the four T-shaped connecting rods are arranged symmetrically with the front and rear protective plates as the center. Two T-shaped sliding grooves are provided, and the two T-shaped sliding grooves are arranged symmetrically with the front and rear protective plates as the center. Two bidirectional threaded rods are provided, and the two bidirectional threaded rods are arranged symmetrically with the front and rear protective plates as the center.

[0007] The above technical solution involves inserting an adjustment handle into the adjustment groove of the bidirectional threaded rod, then rotating the adjustment handle to rotate the bidirectional threaded rod. The bidirectional threaded rod causes the symmetrically arranged T-shaped connecting rods to move inward along the T-shaped sliding groove simultaneously. The symmetrically arranged T-shaped connecting rods drive the front and rear protective plates, which then protect and limit the front and rear of the finned evaporator.

[0008] As a further improvement to the above solution, a T-shaped groove is provided on the top of the protective base, and an H-shaped limiting rod is slidably connected to the inner wall of the T-shaped groove. Left and right protective plates are fixedly connected to the surface of the H-shaped limiting rod.

[0009] As a further improvement to the above solution, two T-shaped slides are provided, and the two T-shaped slides are symmetrically arranged with the left and right protective plates as the center. Four H-shaped limiting rods are provided, and the four H-shaped limiting rods are symmetrically arranged with the left and right protective plates as the center.

[0010] As a further improvement to the above solution, a limiting groove is formed on the inner wall of the T-shaped slide groove, and a limiting block is provided in contact with the inner wall of the limiting groove. The outer wall of the limiting block is slidably connected to the inner wall of the H-shaped limiting rod, and a spring is fixedly connected to the end of the limiting block away from the limiting groove.

[0011] As a further improvement to the above solution, an operating rod is fixedly connected to the end of the limiting block two away from the limiting groove, and a square connecting block is fixedly connected to the end of the operating rod away from the limiting block two. A guide groove is provided on the front of the protective base, and a limiting block three is slidably connected to the inner wall of the guide groove. The outer wall of the square connecting block is slidably connected to the inner wall of the limiting block three, and the outer wall of the limiting block three is fixedly connected to the outer wall of the H-shaped limiting rod. An avoidance groove is provided on the front of the protective base, and a guide block is slidably connected to the inner wall of the avoidance groove. An operating handle is fixedly connected to the end of the square connecting block away from the operating rod, and the outer wall of the square connecting block is slidably connected to the inner wall of the guide block.

[0012] As a further improvement to the above solution, four H-shaped limiting rods are provided, and the four H-shaped limiting rods are symmetrically arranged with the left and right protective plates as the center. Two guide grooves are provided, and the two guide grooves are symmetrically arranged with the left and right protective plates as the center. Two clearance grooves are provided, and the two clearance grooves are symmetrically arranged with the left and right protective plates as the center.

[0013] Through the above technical solution, the H-shaped limiting rod is pushed to slide along the second T-shaped slide groove. At the same time, the H-shaped limiting rod drives the second limiting block to slide along the outer wall of the limiting groove. Simultaneously, the H-shaped limiting rod drives the third limiting block, which in turn drives the square connecting block to slide along the guide groove. The square connecting block drives the guide block, which slides along the clearance groove. At the same time, the square connecting block drives the operating handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention involves placing the finned evaporator on top of a protective base, then inserting an adjustment handle into the adjustment groove of a bidirectional threaded rod. Rotating the adjustment handle causes the bidirectional threaded rod to rotate, causing symmetrically arranged T-shaped connecting rods to move inward along the T-shaped slide groove. The symmetrically arranged T-shaped connecting rods drive the front and rear protective plates, which then protect and limit the finned evaporator. The adjustment handle is then removed from the adjustment groove, and a limiting block is inserted into the adjustment groove. Simultaneously, the limiting block drives a limiting rod into a limiting hole, limiting the bidirectional threaded rod and preventing the T-shaped connecting rod from sliding in the T-shaped slide groove due to the rotation of the bidirectional threaded rod, thus affecting the clamping and protective effect of the front and rear protective plates. This design offers a degree of adjustability and can provide limiting protection for finned evaporators of different sizes.

[0016] This invention pushes an H-shaped limiting rod, causing it to slide along a second T-shaped groove. Simultaneously, the H-shaped limiting rod drives a second limiting block, causing it to slide along the outer wall of the limiting groove. The H-shaped limiting rod also drives a third limiting block, which in turn drives a square connecting block, which slides along a guide groove. The square connecting block drives a guide block, which slides along a clearance groove. Simultaneously, the square connecting block drives the operating handle. When the surfaces of the left and right protective plates contact the surface of the finned evaporator after the front and rear limiting actions, the second limiting block, under the reaction force of the spring, engages inside the limiting groove, preventing it from disengaging without external force. This provides protection by limiting the finned evaporator's left and right sides. Attached Figure Description

[0031] The top of the protective base 1 is provided with a T-shaped slide groove 11, and an H-shaped limiting rod 12 is slidably connected to the inner wall of the T-shaped slide groove 11. Left and right protective plates 13 are fixedly connected to the surface of the H-shaped limiting rod 12.

[0032] Two T-shaped slideways 11 are provided, and the two T-shaped slideways 11 are symmetrically arranged with the left and right protective plates 13 as the center. Four H-shaped limit rods 12 are provided, and the four H-shaped limit rods 12 are symmetrically arranged with the left and right protective plates 13 as the center.

[0033] A limiting groove 14 is provided on the inner wall of the T-shaped slide groove 11. A limiting block 15 is provided in contact with the inner wall of the limiting groove 14. The outer wall of the limiting block 15 is slidably connected to the inner wall of the H-shaped limiting rod 12. A spring 16 is fixedly connected to the end of the limiting block 15 away from the limiting groove 14.

[0034] An operating rod 17 is fixedly connected to the end of the second limiting block 15 away from the limiting groove 14. A square connecting block 18 is fixedly connected to the end of the operating rod 17 away from the second limiting block 15. A guide groove 19 is opened on the front of the protective base 1.

[0035] There are four H-shaped limit rods 12, which are symmetrically arranged with the left and right protective plates 13 as the center. There are two guide grooves 19, which are symmetrically arranged with the left and right protective plates 13 as the center. There are two clearance grooves 21, which are symmetrically arranged with the left and right protective plates 13 as the center.

[0036] The implementation principle of a finned tube evaporator with a protective device in this embodiment is as follows: The finned evaporator is placed on top of the protective base 1. Then, an adjusting handle 7 is inserted into the adjusting groove 6 of the bidirectional threaded rod 5. The adjusting handle 7 is then rotated, causing the bidirectional threaded rod 5 to rotate. This causes the symmetrically arranged T-shaped connecting rods 3 to move inwards along the T-shaped sliding groove 2. The symmetrically arranged T-shaped connecting rods 3 drive the front and rear protective plates 4, which then protect and limit the movement of the finned evaporator. Finally, the adjusting handle 7 is disengaged from the adjusting groove 6, and a limiting block is inserted into the adjusting groove 6. 8. Simultaneously, the limiting block 8 drives the limiting rod 10 to insert into the limiting hole 9, limiting the bidirectional threaded rod 5 to prevent the bidirectional threaded rod 5 from rotating and causing the T-shaped connecting rod 3 to slide in the T-shaped slide groove 2, affecting the clamping and protective effect of the front and rear protective plates 4. By pushing the H-shaped limiting rod 12, the H-shaped limiting rod 12 slides along the second T-shaped slide groove 11. At the same time, the H-shaped limiting rod 12 drives the second limiting block 15, causing the second limiting block 15 to slide along the outer wall of the limiting groove 14. At the same time, the H-shaped limiting rod 12 drives the third limiting block 20, which in turn drives the square connecting block 18. The third limiting block 20 slides along the guide groove 19, and the square connecting block 18... Block 18 drives guide block 23, which slides along clearance groove 21. Simultaneously, square connecting block 18 drives operating handle 22. When the surfaces of left and right protective plates 13 contact the finned evaporator surface after front and rear limiters, limit block 25, under the reaction force of spring 16, engages inside limit groove 14, thereby limiting operating rod 17. Operating rod 17 limits H-shaped limit rod 12, H-shaped limit rod 12 limits square connecting block 18, and square connecting block 18 limits block 3 20 and guide block 23, preventing limit block 2 15 from disengaging from limit groove 14 without external human intervention. This limits the left and right movement of the finned evaporator. When it is necessary to remove the second limiting block 15 from the limiting groove 14, the operating handle 22 is pulled outward. The operating handle 22 pulls the square connecting block 18, causing the square connecting block 18 to slide along the inner wall of the guide block 23 and the third limiting block 20. At the same time, the square connecting block 18 pulls the operating rod 17, which pulls the second limiting block 15, causing the surface of the second limiting block 15 to disengage from the limiting groove 14. Simultaneously, the second limiting block 15 compresses the spring 16 inward, thereby unlocking the second limiting block 15 from restricting the H-shaped limiting rod 12. It has a certain degree of adjustability and can provide limiting protection for finned evaporators of different sizes.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
