Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology and relates to a locking structure for a detachable refrigeration unit. Background Technology

[0002] A refrigeration unit is a core piece of equipment that forcibly transfers heat from a low-temperature environment to a high-temperature environment, thereby providing a continuous and stable low-temperature environment or precise temperature control for various application scenarios, achieving refrigeration or low-temperature maintenance. It is widely used in industrial, commercial and civil fields.

[0003] Traditional refrigeration units typically employ a fixed installation design, with core components such as compressors and condensers tightly integrated with the protective casing. While this structure can improve equipment stability, it requires the removal of numerous fixed components when disassembling for maintenance or replacement. This is not only time-consuming and labor-intensive but also prone to low maintenance efficiency due to limited operating space, and may even increase the risk of equipment damage. Utility Model Content

[0004] The technical problem to be solved by this utility model is that traditional refrigeration units usually adopt a fixed installation design, and their core components such as compressors and condensers are tightly integrated with the protective shell. Although this structure can improve the stability of the equipment, when it is necessary to disassemble, repair or replace parts, a large number of fixed parts must be removed first. This is not only time-consuming and labor-intensive, but also prone to low maintenance efficiency due to limited operating space, and may even increase the risk of equipment damage.

[0005] The present invention discloses a locking structure for a detachable refrigeration unit, comprising a protective outer shell, a cover connected to the top of the protective outer shell, a trapezoidal base installed in the middle of the protective outer shell, a refrigeration unit body installed in the middle of the trapezoidal base, and a locking component provided in the middle of the protective outer shell.

[0006] The locking assembly includes a bidirectional lead screw, a support guide rod, a turntable, and two sets of sliding plates. The two ends of the bidirectional lead screw are rotatably connected to both sides of the protective shell. The two ends of the support guide rod are fixed to both sides of the protective shell. The turntable is fixed to one end of the bidirectional lead screw. The threads at both ends of the bidirectional lead screw have opposite directions. One end of each of the two sliding plates is threaded to both sides of the middle of the bidirectional lead screw, and the other ends of each sliding plate are slidably connected to the middle of the support guide rod.

[0007] The locking assembly also includes four sets of hollow sleeves, four sets of sliding rods, and four sets of support pulleys. The four hollow sleeves are respectively fixed to the middle sides of the two sets of sliding plates. The four sliding rods are respectively slidably connected to the middle of the four sets of hollow sleeves. The four support pulleys are respectively installed at the bottom of the four sets of sliding rods. Each of the four hollow sleeves is provided with a limit mechanism in the middle.

[0008] The locking assembly also includes two sets of connecting plates, two sets of clamping plates, and two sets of counterweights. One side of each of the two connecting plates is fixed to the side of the two sets of sliding plates that are close to each other. One side of each of the two clamping plates is fixed to the side of the two sets of connecting plates that is away from the sliding plates. The two counterweights are fixed to both sides of each set of support pulleys.

[0009] The locking assembly also includes four sets of rectangular plates and four sets of limiting blocks. The four rectangular plates are respectively fixed to the top of the four sets of sliding rods, and the four limiting blocks are all fixed to the bottom surface of the shell cover. A T-shaped groove is opened in the middle of each of the four limiting blocks.

[0010] The limiting mechanism includes two sets of limiting guide rails and two sets of limiting slide grooves. The two limiting guide rails are fixed to the inner ring of each set of hollow sleeves, and the two limiting slide grooves are opened on the outside of each set of slide rods. Each set of limiting guide rails is in contact with each set of limiting slide grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the locking component, the main body of the refrigeration unit can be easily disassembled and assembled, which not only greatly shortens the equipment downtime caused by disassembly, maintenance or replacement of parts, reduces the intensity of manual operation, and significantly improves maintenance efficiency and quality, but also reduces the risk of secondary damage such as component collisions and pipeline damage caused by forced disassembly or confined space.

[0012] By setting a limiting mechanism, the movement trajectory of the slide bar can be easily restricted, thereby reducing the possibility of the slide bar easily deviating to the left or right due to lack of restriction when sliding, which in turn causes the angle of the rectangular plate to change, making it difficult for the rectangular plate to be accurately inserted into the T-slot and affecting the stability of the locking component.

[0026] Example 1

[0027] like Figures 1 to 7 As shown, a locking structure for a detachable refrigeration unit includes a protective outer shell 1, a cover 11 connected to the top of the protective outer shell 1, a trapezoidal base 12 installed in the middle of the protective outer shell 1, a refrigeration unit body 13 installed in the middle of the trapezoidal base 12, and a locking component provided in the middle of the protective outer shell 1.

[0028] The locking assembly includes a bidirectional lead screw 2, a support guide rod 21, a turntable 22, and two sets of sliding plates 23. The two ends of the bidirectional lead screw 2 are rotatably connected to both sides of the protective shell 1, the two ends of the support guide rod 21 are fixed to both sides of the protective shell 1, the turntable 22 is fixed to one end of the bidirectional lead screw 2, the two ends of the bidirectional lead screw 2 have opposite thread directions, one end of the two sliding plates 23 is threaded to both sides of the middle of the bidirectional lead screw 2, and the other end of the two sliding plates 23 is slidably connected to the middle of the support guide rod 21.

[0029] The locking assembly also includes four sets of hollow sleeves 3, four sets of sliding rods 31, and four sets of support pulleys 32. The four hollow sleeves 3 are respectively fixed to the middle sides of the two sets of sliding plates 23. The four sliding rods 31 are respectively slidably connected to the middle of the four sets of hollow sleeves 3. The four support pulleys 32 are respectively installed at the bottom of the four sets of sliding rods 31. Each of the four hollow sleeves 3 is provided with a limit mechanism in the middle.

[0030] The locking assembly also includes two sets of connecting plates 4, two sets of clamping plates 41, and two sets of counterweights 42. One side of each of the two connecting plates 4 is fixed to the side of each of the two sets of sliding plates 23 that are close to each other. One side of each of the two clamping plates 41 is fixed to the side of each of the two sets of connecting plates 4 that is away from the sliding plates 23. The two counterweights 42 are fixed to both sides of each set of support pulleys 32.

[0031] The locking assembly also includes four sets of rectangular plates 5 and four sets of limiting blocks 51. The four rectangular plates 5 are respectively fixed to the top of the four sets of sliding rods 31, and the four limiting blocks 51 are all fixed to the bottom surface of the cover 11. A T-shaped groove 52 is opened in the middle of each of the four limiting blocks 51.

[0032] When it is necessary to lock the main body 13 of the freezer during operation, the main body 13 of the freezer and the trapezoidal base 12 can be placed in the middle of the protective shell 1 and the shell cover 11 can be closed. Then, the turntable 22 is rotated to drive the double-acting screw 2 to rotate on both sides of the protective shell 1. When the double-acting screw 2 rotates, it will drive the two sets of sliding plates 23 to move. When the sliding plates 23 move, they will be restricted by the support guide rod 21, so that the sliding plates 23 slide in a straight line between the support guide rod 21 and the double-acting screw 2. When the two sets of sliding plates 23 slide, they will be restricted by the opposite direction of the threads at both ends of the double-acting screw 2, so that the two sets of sliding plates 23 will drive the connecting plate 4 and the clamping plate 41 to gradually approach each other until the two sets of clamping plates 41 are moved to fit against both sides of the freezer main body 13. Then the turntable 22 can be stopped to complete the function of clamping both sides of the freezer main body 13.

[0033] When the slide plate 23 slides, it drives the bidirectional lead screw 2, slide rod 31, rectangular plate 5, support pulley 32, and counterweight 42 to move synchronously. The counterweight 42 increases the weight of the support pulley 32, ensuring that the bottom of the support pulley 32 remains in contact with the bottom of the trapezoidal base 12 or the protective shell 1. When the slide plate 23 moves to the inclined surfaces on both sides of the trapezoidal base 12, the support pulley 32, influenced by the trapezoidal base 12, drives the slide rod 31 to slide upwards in the middle of the hollow sleeve 3. The sliding of the slide rod 31 drives the rectangular plate 5 to move synchronously. When the support pulley 32 moves to the trapezoidal base 12... When the top surface is flat, the slide bar 31 will stop sliding. At this time, as the slide plate 23 continues to move, the rectangular plate 5 will gradually move towards the limiting block 51. When the clamping plate 41 is in contact with the freezer body 13, the rectangular plate 5 will be inserted into the T-shaped groove 52. Thus, with the cooperation between the T-shaped groove 52, the rectangular plate 5, the slide bar 31 and the supporting pulley 32, the trapezoidal base 12 can be pressed down, thereby completing the work of positioning the trapezoidal base 12 vertically. When the freezer body 13 needs to be disassembled for maintenance, the turntable 22 is rotated in the opposite direction to make the locking component disengage from the freezer body 13.

[0034] This step, through the setting of the locking component, enables convenient disassembly and assembly of the main body 13 of the refrigeration unit. This not only significantly shortens the equipment downtime caused by disassembly, maintenance or replacement of parts, reduces the intensity of manual operation, and significantly improves maintenance efficiency and quality, but also reduces the risk of secondary damage such as component collisions and pipeline damage caused by forced disassembly or confined space.

[0035] Example 2

[0036] like Figure 6 and Figure 7 As shown, the limiting mechanism includes two sets of limiting guide rails 6 and two sets of limiting slide grooves 61. The two limiting guide rails 6 are fixed to the inner ring of each set of hollow sleeves 3, and the two limiting slide grooves 61 are opened on the outside of each set of slide rods 31. Each set of limiting guide rails 6 and each set of limiting slide grooves 61 are respectively in contact with each other.

[0037] During operation, when the slide rod 31 slides against the middle of the hollow sleeve 3, it will drive the limiting slide groove 61 to slide at the limiting guide rail 6. With the cooperation of the limiting slide groove 61 and the limiting guide rail 6, the sliding trajectory of the slide rod 31 can be restricted.

[0038] This step, through the setting of the limiting mechanism, can easily restrict the movement trajectory of the slide bar 31, thereby reducing the possibility that the slide bar 31 may easily deviate to the left or right due to lack of restriction when sliding, which in turn will cause the angle of the rectangular plate 5 to change, making it difficult for the rectangular plate 5 to be accurately inserted into the T-shaped groove 52, thus affecting the stability of the locking component.
