Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a low-temperature horizontal refrigeration equipment for warehousing. Background Technology

[0002] With the rapid development of the cold chain logistics industry, low-temperature horizontal refrigeration equipment for warehousing has been widely used in the food, pharmaceutical and other fields. Currently, this type of equipment on the market mainly consists of basic components such as a low-temperature refrigeration cabinet, a refrigeration system, and an insulation layer. Mechanical or electronic locks are used to secure the cabinet lid. These devices are generally large and heavy, requiring frequent repositioning to meet different storage needs in the warehousing environment. Simultaneously, to maintain the low-temperature environment, the equipment needs excellent sealing performance, which places high demands on the connection and fixation between the cabinet lid and the low-temperature refrigeration cabinet.

[0003] However, existing low-temperature horizontal refrigeration equipment still has many shortcomings: First, traditional locks have simple structures, relying on a single locking point for fixation, which are prone to loosening after long-term use, resulting in poor sealing of the cabinet lid and serious cold air leakage; second, the equipment lacks intelligent linkage functions when opened, requiring operators to turn on additional lighting, increasing the number of operating steps; third, existing locking mechanisms cannot provide intuitive status indicators, easily leading to energy waste due to the cabinet lid not being fully locked; in addition, the design of the equipment's moving mechanism is unreasonable, usually only having fixed handles, requiring multiple people to cooperate when moving heavy equipment, seriously affecting work efficiency. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a low-temperature horizontal refrigeration equipment for storage, so as to solve the problem of insufficient sealing of traditional equipment.

[0005] To achieve the above objectives, this utility model provides a low-temperature horizontal refrigeration equipment for warehousing, comprising: a low-temperature refrigeration cabinet, wherein a cabinet cover is installed on the top of the low-temperature refrigeration cabinet;

[0006] A pushing component is installed on both symmetrical sides of the low-temperature refrigeration cabinet, and the pushing component is used to push and pull the low-temperature refrigeration cabinet.

[0007] A fixing component is installed on the same side of the low-temperature refrigeration cabinet body and the cabinet cover, and the fixing component is used to further fix the cabinet cover and the low-temperature refrigeration cabinet body.

[0008] Preferably, the pushing component includes storage slots fixedly installed on both sides of the low-temperature refrigeration cabinet, and a pull rod is rotatably installed in each storage slot.

[0009] Preferably, the fixing component includes a first trigger shell and a second trigger shell fixedly installed on one side of the low-temperature refrigeration cabinet. A switch is installed inside the first trigger shell. A lock shell is fixedly installed on the cabinet cover near the second trigger shell. Two mating teeth are symmetrically fixedly installed inside the lock shell. Two locking teeth are rotatably installed on the second trigger shell near the lock shell. The locking teeth are adapted to the mating teeth.

[0010] Preferably, a drive block is slidably installed inside the second trigger housing, and a push block is fixedly installed on the drive block, with one side of the push block abutting against one side of the locking tooth.

[0011] Preferably, a partition is fixedly installed inside the second trigger housing, and a movable groove is formed on the second trigger housing, the movable groove passing through the second trigger housing and the partition. The drive block is slidably installed in the movable groove, and a sliding groove is formed on the side of the drive block near the partition. An assist block is fixedly installed on the end of the drive block away from the sliding groove. A mating block is slidably installed on the side of the partition near the locking tooth, and the mating block is slidably installed in the sliding groove.

[0012] Preferably, a trigger rod is fixedly installed on one side of the mating block, a return spring is sleeved on the trigger rod, a connecting block is fixedly installed on the side of the mating block away from the trigger rod, a push rod is fixedly installed on the side of the connecting block away from the mating block, and a trigger plate is fixedly installed on the end of the push rod away from the mating block.

[0013] Preferably, through holes are provided on both symmetrical sides of the second trigger housing, the push rod is slidably installed in the through holes, and the end of the trigger rod away from the mating block passes through the other through hole and extends into the interior of the first trigger housing.

[0014] Preferably, a protective shell is installed on the side of the second trigger shell near the lock shell, and receiving grooves are provided on both symmetrical sides of the protective shell, the receiving grooves being adapted to the lock teeth.

[0015] Preferably, a display screen is installed on one side of the low-temperature refrigeration cabinet, several wheels are installed on the bottom of the low-temperature refrigeration cabinet, and handles are symmetrically installed on both sides of the low-temperature refrigeration cabinet.

[0016] The beneficial effects of this utility model are:

[0017] 1. This type of low-temperature horizontal refrigeration equipment for storage, through the installation of fixed components and a mechanical linkage mechanism, achieves automatic locking and unlocking of the cabinet cover and the low-temperature refrigeration cabinet body. In the initial state, the spring force of the return spring keeps the locking teeth and mating teeth engaged, ensuring the cabinet cover is securely locked. When unlocking is required, pushing the trigger plate causes the drive block to retract inward, causing the assist block to deflect the locking teeth, releasing the lock on the mating teeth. Simultaneously, the trigger rod presses the switch, automatically turning on the cabinet's internal lighting and display screen. When closing the cabinet cover, pushing the trigger plate again deflects the locking teeth, at which point the trigger rod presses the switch again, and the cabinet cover closes. After the trigger plate is released, the return spring resets the locking teeth, re-engages the mating teeth to complete the locking process, and automatically turns off the lighting and display screen. The engaged locking teeth and mating teeth form a reliable lock under the action of the return spring, ensuring the airtightness of the low-temperature refrigeration cabinet and the cabinet cover. A single push of the trigger plate can simultaneously complete the intelligent operation of unlocking and lighting activation, greatly improving ease of use. The unique locking status and display screen linkage mechanism provides intuitive safety indications. This allows the equipment to maintain low-temperature storage performance while significantly improving operational safety and maintenance convenience, perfectly adapting to the needs of various warehousing environments.

[0018] 2. This type of low-temperature horizontal refrigeration equipment for storage, by setting up a pushing component, and through a dual force-applying structure of a rotatable and retractable pull rod and a fixed handle, allows the equipment to be moved by providing the main thrust through the pull rod and the auxiliary force through the handle. This significantly improves the ease of movement of large refrigeration equipment in the storage environment, solves the problem of difficult movement of traditional horizontal refrigeration equipment, and enables operators to complete the position adjustment of the equipment by a single person, greatly improving work efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 3 As shown, a low-temperature horizontal refrigeration equipment for storage includes: a low-temperature refrigeration cabinet 1, a display screen 5 installed on one side of the low-temperature refrigeration cabinet 1, several wheels 4 installed on the bottom of the low-temperature refrigeration cabinet 1, handles 2 symmetrically installed on both sides of the low-temperature refrigeration cabinet 1, and a cabinet cover 3 installed on the top of the low-temperature refrigeration cabinet 1; a pushing component, which is installed on both symmetrical sides of the low-temperature refrigeration cabinet 1 and is used to push and pull the low-temperature refrigeration cabinet 1; and a fixing component, which is installed on the same side of the low-temperature refrigeration cabinet 1 and the cabinet cover 3 and is used to further fix the cabinet cover 3 and the low-temperature refrigeration cabinet 1.

[0028] When using this equipment, the operator can smoothly push and pull the cryogenic refrigeration cabinet 1 using the pushing components symmetrically installed on both sides of the cabinet. Several wheels 4 at the bottom ensure the equipment can be flexibly moved to the desired working position. In the initial state, the cabinet cover 3 and the cryogenic refrigeration cabinet 1 are firmly locked together by the fixing components. The cover 3 and the cabinet 1 are magnetically closed, and this double fixing mechanism effectively ensures the airtightness and temperature stability of the storage space. When it is necessary to open the cover 3, operating the fixing components will automatically trigger the built-in light source button switch. At this time, the display screen 5 installed on the side of the cryogenic refrigeration cabinet 1 will immediately power on and start, providing not only a clear parameter display function, but also... The internal lighting system of the low-temperature refrigeration cabinet 1 is activated synchronously, providing ample internal illumination for storing and retrieving items, significantly improving operational convenience. Notably, the on / off status of the display screen 5 serves as a direct visual indicator of the tightness of the fixed components: when the display screen 5 is lit normally, it indicates that the cabinet cover 3 is open, while when the display screen 5 is off, it indicates that the cabinet cover 3 is closed. This design allows operators to quickly assess the safety status of the equipment, ensuring both operational convenience and safety. The entire system, through the synergistic effect of mechanical structure and electrical components, achieves multi-functional integration of low-temperature storage, convenient relocation, and status indication, fully meeting the professional refrigeration needs of the storage environment. Furthermore, the low-temperature refrigeration cabinet 1 is existing technology and will not be described in detail here.

[0029] like Figure 1 As shown, the pushing component includes storage slots 6 fixedly installed on both sides of the low-temperature refrigeration cabinet 1, and pull rods 7 are rotatably installed in each storage slot 6;

[0030] When the cryogenic refrigeration cabinet 1 needs to be moved, the operator can rotate the pull rod 7, which is rotatably installed in the storage slot 6, from the storage state to the working position, forming an ergonomic force application fulcrum. Together with the several wheels 4 set at the bottom of the cryogenic refrigeration cabinet 1, the operator can achieve smooth movement of the equipment with a small force. During the handling process, the handles 2 symmetrically arranged on both sides of the cryogenic refrigeration cabinet 1 can provide additional force application points, working in conjunction with the pull rod 7 to further enhance the stability and convenience of handling.

[0031] like Figure 2 , Figure 3As shown, the fixing assembly includes a first trigger housing 12 and a second trigger housing 17 fixedly installed on one side of the low-temperature refrigeration cabinet 1. A switch 13 is installed inside the first trigger housing 12. A lock housing 8 is fixedly installed on the cabinet cover 3 near the second trigger housing 17. Two mating teeth 9 are symmetrically fixedly installed inside the lock housing 8. Two locking teeth 11 are rotatably installed on the second trigger housing 17 near the lock housing 8. The locking teeth 11 are adapted to the mating teeth 9. A drive block 20 is slidably installed inside the second trigger housing 17. A push block 21 is fixedly installed on the drive block 20. One side of the push block 21 abuts against one side of the locking teeth 11. A partition 25 is fixedly installed inside the second trigger housing 17. A movable groove 24 is opened on the second trigger housing 17, which passes through the second trigger housing 17 and the partition 25. The drive block 20 is slidably installed in the movable groove 24. A sliding groove 22 is opened on the drive block 20 near the partition 25. A booster block 28 is fixedly installed at one end of the slide 22. A mating block 15 is slidably installed on the side of the partition 25 near the locking tooth 11. The mating block 15 is slidably installed in the slide groove 22. A trigger rod 26 is fixedly installed on one side of the mating block 15. A return spring 18 is sleeved on the trigger rod 26. A connecting block 16 is fixedly installed on the side of the mating block 15 away from the trigger rod 26. A push rod 14 is fixedly installed on the side of the connecting block 16 away from the mating block 15. A trigger plate 27 is fixedly installed at the end of the push rod 14 away from the mating block 15. Through holes 23 are opened on both sides of the second trigger shell 17. The push rod 14 is slidably installed in the through holes 23. The end of the trigger rod 26 away from the mating block 15 passes through another through hole 23 and extends into the interior of the first trigger shell 12. A protective shell 10 is installed on the side of the second trigger shell 17 near the lock shell 8. Receiving grooves 19 are opened on both sides of the protective shell 10. The receiving grooves 19 are adapted to the locking tooth 11.

[0032] In the initial state of the equipment, the cabinet cover 3 and the low-temperature refrigeration cabinet 1 are double-locked by a fixing component. At this time, the mating teeth 9 in the lock housing 8 and the locking teeth 11 on the second trigger housing 17 are stably engaged under the elastic potential energy provided by the return spring 18, forming a reliable mechanical lock. When it is necessary to open the cabinet cover 3, the operator pushes the trigger plate 27 inward, which drives the mating block 15 to slide along the slide groove 22 through the push rod 14, thereby driving the drive block 20 to retract into the second trigger housing 17. During this process, the assist block 28 pushes the locking teeth 11 to deflect, releasing the engagement lock with the mating teeth 9. At the same time, the trigger rod 26 passes through the through hole 23 into the first trigger housing 12 and triggers the switch 13, which synchronously powers on the internal lighting system and display screen 5 of the low-temperature refrigeration cabinet 1, providing both operational lighting and status indication. It is worth noting that when the trigger plate 27 is released, the elastic restoring force of the return spring 18 will cause the entire trigger mechanism to automatically reset, while the cabinet cover 3 remains open. When closing the cabinet cover 3... The trigger plate 27 needs to be pushed again to deflect the locking tooth 11 to provide movement space for the mating tooth 9. During this process, the switch 13 is triggered again, and the cabinet lighting and display screen 5 are turned off. After the cabinet cover 3 is completely closed with the low-temperature refrigeration cabinet 1, the trigger plate 27 is released, the reset spring 18 pushes the mating block 15 to reset, the drive block 20 moves accordingly, and pushes the locking tooth 11 back to the meshing position with the mating tooth 9 through the push block 21, completing the locking process. The protective shell 10 and the receiving grooves 19 on both sides provide guidance and movement space for the movement of the locking tooth 11, ensuring the stable operation of the locking mechanism. The fixing component realizes the synchronization of the opening and closing of the cabinet cover 3 and the electrical control through mechanical linkage and spring reset system, which not only ensures the sealing of the low-temperature storage environment, but also improves the operation convenience and safety of the equipment through intelligent status indication function. This device works together with the push component, wheels 4 and other moving mechanisms to form a professional low-temperature storage system with complete functions and convenient operation, which fully meets the high standard requirements of modern warehousing environment for refrigeration equipment.
