Description

Technical Field

[0001] This utility model belongs to the field of low-temperature cold chain equipment, and specifically relates to a low-temperature constant temperature storage box. Background Technology

[0002] In the fields of medicine, scientific research, and industry, low-temperature constant-temperature storage chambers are devices specifically designed for storing temperature-sensitive items. Through a specific refrigeration system and temperature monitoring and control system, the chambers can continuously and stably maintain a low temperature, such as -20℃, -40℃, -60℃, or even -80℃, to meet the low-temperature storage requirements of different samples and items. This ensures that they remain in a suitable temperature environment during long-term storage, maintaining their quality, activity, performance, and related characteristics, and providing reliable cold chain protection facilities for research, production, and preservation in related fields.

[0003] In practical applications, traditional low-temperature constant-temperature storage tanks, due to their large size, typically rely on three-stage cascade cooling systems for cooling. However, the wiring connections between the inlet and outlet pipes often have design flaws, resulting in irrational wiring layouts and haphazardly placed pipes during refrigerant transport. This not only affects the aesthetics of the equipment but also poses safety hazards. Especially when the equipment is running or personnel are passing by, the messy pipes on the ground are easily damaged by crushing or trampling, which can lead to refrigerant leaks, affecting the normal operation and cooling effect of the storage tank, and potentially threatening the safety of on-site personnel and equipment. Therefore, it is essential to provide a low-temperature constant-temperature storage tank with a reasonable design, neat and aesthetically pleasing wiring, high safety and reliability, improved refrigerant transfer efficiency, prevention of pipe damage, and extended pipe lifespan.

[0008] Preferably, the guide plate has an arc-shaped surface structure, and the protruding surface of the arc-shaped surface is flush with the arc-shaped side surface of the double-tube clamp.

[0009] Preferably, the cross-section of the protrusion A is a T-shaped structure, the cross-sectional dimension of the protrusion A is the same as the cross-sectional dimension of the T-shaped groove, the cross-sectional dimension of the protrusion B is the same as the cross-sectional dimension of the straight groove, the protrusion A can slide in the T-shaped groove, and the protrusion B can slide in the straight groove.

[0010] Preferably, the arc-shaped guide frame includes an arc-shaped body, ear plates, round steel bars, and steel wires. The arc-shaped body has a semi-circular cross-section. The arc-shaped body has horizontally symmetrically arranged liquid inlet and liquid outlet channels inside. The liquid inlet channel is for the liquid inlet pipe to pass through, and the liquid outlet channel is for the liquid outlet pipe to pass through. The ear plates are symmetrically fixed at the bottom of the side of the arc-shaped body. The ear plates have uniformly distributed through holes. The round steel bars are uniformly welded to the interior of the arc-shaped body along the axial direction of the arc-shaped body. The steel wires are distributed in the radial direction of the round steel bars and are perpendicular to the axis of the round steel bars. The two ends of the steel wires are connected to the round steel bars. The cross-sections at the connection points of the steel wires and the round steel bars together form several triangular structures.

[0011] Preferably, the round steel is hot-rolled round steel, and the steel wire is galvanized steel wire.

[0012] Preferably, the height of the outlet tank is higher than that of the inlet tank, and a top fixing component spanning the width direction of the outlet tank is provided at the top of the outlet tank. The two ends of the top fixing component are fixedly connected to the housing. A bottom fixing component spanning the width direction of the outlet tank and the inlet tank is provided at the lower part of the parallel section of the outlet tank and the inlet tank. The two ends of the bottom fixing component are fixedly connected to the housing.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model employs a method where the inlet pipe and outlet pipe are placed in the inlet tank and outlet tank respectively, and the inlet pipe and outlet pipe at the horizontal part of the inlet tank and outlet tank are limited and fixed by a double pipe guide assembly. This avoids the problem of the inlet pipe and outlet pipe being scattered, improves the aesthetics of the pipeline wiring, and at the same time, the fixation of the inlet pipe and outlet pipe by the inlet tank, outlet tank and double pipe guide assembly prevents the external insulation sleeve from shifting and causing the pipeline to leak, resulting in refrigerant leakage. The fixation of the insulation sleeve further improves the efficiency of refrigerant transmission.

[0017] 2. By creating evenly distributed notches A and B on the horizontal part of the liquid inlet tank, when the storage tank needs to be placed in different locations, the liquid inlet pipe and liquid outlet pipe can be pushed to the vicinity of notches A and B, which will not affect the operation of the equipment, by pushing the dual-pipe guide assembly. Then, wiring can be carried out from there, realizing wiring operations in different scenarios and expanding the scope of application and usage scenarios.

[0018] 3. The use of arc-shaped guide frames can protect and organize the inlet and outlet pipes scattered on the ground, avoiding damage from external forces such as crushing and trampling. The triangular structure formed by steel wire and round steel inside the arc-shaped guide frame enhances the external bearing capacity of the arc-shaped guide frame, ensuring that the inlet and outlet pipes inside are not damaged. At the same time, it also improves the safety and stability of the overall structure, avoids pipe damage, and extends the service life of the pipes.

[0019] 4. The design of using top and bottom fixing components ensures radial limitation of the inlet and outlet pipes in the vertical part of the inlet and outlet tanks, significantly improving the aesthetics of the overall structure.

[0020] In summary, this utility model has a reasonable design, neat and beautiful wiring, safe and reliable operation, improved refrigerant transmission efficiency, avoided pipeline damage, extended pipeline service life, and expanded its application scope. Attached Figure Description

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figure 1-9 As shown, a low-temperature constant-temperature storage box includes a box body 1. A liquid inlet trough 101 and a liquid outlet trough 102 are provided on the side of the box body 1. The liquid inlet trough 101 and the liquid outlet trough 102 are closely adjacent to each other in an L-shape. Several evenly distributed notches A103 are also provided on the bottom side of the box body 1. A notch B104, closely adjacent to the notch A103, is provided on the right side of the notch A103. The tops of the notches A103 and B104 are connected to the horizontal portion of the liquid inlet trough 101. A double-pipe guide assembly 6 is slidably connected within the horizontal portions of the liquid inlet trough 101 and the liquid outlet trough 102. A liquid inlet is provided within the liquid inlet trough 101. The inlet pipe 4 and outlet pipe 5 are provided in the outlet tank 102. The top ends of the inlet pipe 4 and outlet pipe 5 are sealed to the box body 1. The top ends of the inlet pipe and outlet pipe 5 are provided with switches 2. The inlet pipe 4 and outlet pipe 5 extend downward from the vertical part of the inlet tank 101 and outlet tank 102 to the horizontal part of the inlet tank 101 and outlet tank 102 and pass through the double pipe guide assembly 6. After being fixed by the double pipe guide assembly 6, they extend downward along the nearest notch A103 and notch B104 to the arc-shaped guide frame 7 on the ground. The output ends of the inlet pipe 4 and outlet pipe 5 pass through the arc-shaped guide frame 7 and are sealed to the three-stage cascade device 8.

[0033] The liquid inlet tank 101 has a straight groove 106 at the bottom of its horizontal section and a T-shaped groove 105 at the top of its horizontal section. Both the straight groove 106 and the T-shaped groove 105 are used to fix the double-tube guide assembly 6, ensuring that the double-tube guide assembly 6 can stay in the horizontal section of the liquid inlet tank 101 and the liquid outlet tank 102 without falling off, and also ensuring that the double-tube guide assembly 6 can slide freely in the horizontal section of the liquid inlet tank 101 and the liquid outlet tank 102.

[0034] The dual-tube guide assembly 6 includes a dual-tube clamp 601, a protrusion A602, a protrusion B603, and a guide plate 604. The protrusion A602 is fixedly installed on the top of the dual-tube clamp 601, the protrusion B603 is fixedly installed on the bottom of the dual-tube clamp 601, and the guide plate 604 is fixedly installed on the right side of the dual-tube clamp 601. The guide plate 604 has an arc-shaped surface structure, and the protruding surface of the arc-shaped surface is flush with the arc-shaped side surface of the dual-tube clamp 601.

[0035] The guide plate 604 is designed with an arc-shaped surface structure. The inner surface of the guide plate 604 can better fit the surfaces of the inlet pipe 4 and the outlet pipe 5. On the one hand, it can avoid damage to the inlet pipe 4 and the outlet pipe 5. On the other hand, it can push the inlet pipe 4 and the outlet pipe 5 more smoothly, so that they can be inserted into the corresponding inlet groove 101 and outlet groove 102 more quickly. At the same time, when the inlet pipe 4 and the outlet pipe 5 extend downward from the nearest notch A103 and notch B104, the two protruding arc-shaped surfaces can block the sides of the downward bending inlet pipe 4 and the outlet pipe 5, and bear the bending force of the inlet pipe 4 and the outlet pipe 5. This prevents the inlet pipe 4 and the outlet pipe 5 from entering the notch A103 and notch B104 due to bending, and prevents the upper part of the inlet pipe 4 and the outlet pipe 5 from leaving the inlet groove 101 and the outlet groove 102.

[0036] Among them, the cross-section of protrusion A602 is a T-shaped structure, and the cross-sectional dimensions of protrusion A602 are the same as those of T-groove 105. The cross-sectional dimensions of protrusion B603 are the same as those of straight groove 106. Protrusion A602 can slide within T-groove 105. The T-shaped cross-section design of protrusion A602 has a good limiting function. When protrusion A602 is inserted into T-groove 105, it can prevent protrusion A602 from falling out of T-groove 105, ensuring better limiting of the double tube guide assembly 6. Protrusion B603 can slide within straight groove 106, further ensuring that the double tube guide assembly 6 can slide freely in the horizontal part of liquid inlet groove 101 and liquid outlet groove 102.

[0037] The arc-shaped guide frame 7 includes an arc-shaped body 701, ear plates 704, round steel 706, and steel wires 707. The arc-shaped body 701 has a semi-circular cross-section. The arc-shaped body 701 has horizontally symmetrically arranged liquid inlet channels 702 and liquid outlet channels 703. The liquid inlet channel 702 is used for the liquid inlet pipe 4 to pass through, and the liquid outlet channel 703 is used for the liquid outlet pipe 5 to pass through. The ear plates 704 are symmetrically fixed at the bottom of the side of the arc-shaped body 701. The ear plates 704 have evenly distributed through holes 705. The round steel 706 is evenly welded to the inside of the arc-shaped body 701 along the axial direction. The steel wires 707 are distributed in the radial direction of the round steel 706 and are perpendicular to the axis of the round steel 706. The two ends of the steel wires 707 are connected to the round steel 706. The cross-sections at the connection points of the steel wires 707 and the round steel 706 together form several triangular structures.

[0038] The triangular structure formed by the steel wire 707 and round steel 706 inside the arc-shaped guide frame 7 enhances the external bearing capacity of the arc-shaped guide frame 7, ensuring that the inlet pipe 4 and outlet pipe 5 inside are not damaged. It also improves the safety and stability of the overall structure, avoids damage to the pipe 9, and extends the service life of the pipe 9. The through hole 705 on the ear plate 704 can fix the arc-shaped guide frame 7 to the ground with expansion bolts, further improving the stability of the arc-shaped guide frame 7, ensuring the integrity of the inlet pipe 4 and outlet pipe 5 inside, extending the service life of the inlet pipe 4 and outlet pipe 5, and further improving the aesthetics of the overall equipment. The cross-section of the arc-shaped body 701 adopts a semi-circular structure. When subjected to external impact or pressure, the semi-circular structure can better and more evenly distribute the external force, thereby reducing local stress concentration, reducing the risk of structural damage, and improving the stability of the overall structure.

[0039] Among them, the round steel 706 is hot-rolled round steel, and the steel wire 707 is galvanized steel wire. The hot-rolled round steel is the main supporting material of the arc-shaped guide frame 7. Its strength is moderate and it can withstand large mechanical stress. The galvanized steel wire 707 can enhance its corrosion resistance and ensure that it is not easy to rust during long-term use. The combined use of hot-rolled round steel and galvanized steel wire significantly improves the supporting strength of the arc-shaped guide frame 7 and ensures internal stability.

[0040] The height of the outlet tank 102 is higher than that of the inlet tank 101. A top fixing component 11 spanning the width of the outlet tank 102 is provided at the top of the outlet tank 102. Both ends of the top fixing component 11 are fixedly connected to the housing 1. A bottom fixing component 3 spanning the width of the outlet tank 102 and the inlet tank 101 is provided at the lower part of the parallel section of the outlet tank 102 and the inlet tank 101. Both ends of the bottom fixing component 3 are fixedly connected to the housing 1.

[0041] The coordinated design of the top fixing component 11 and the bottom fixing component 3 ensures the radial limitation of the inlet pipe 4 and the outlet pipe 5 within the vertical sections of the inlet tank 101 and the outlet tank 102, significantly improving the overall aesthetics of the structure.

[0042] The top fixing assembly 11 and the bottom fixing assembly 3 each include a rotating rod 301, a pin 302, a retaining shaft 304, and an end cap 305. The rotating rod 301 is located on the right side of the liquid outlet tank 102. The pin 302 is located at the connection between the rotating rod 301 and the housing 1, and is used to fix and limit the rotating rod 301 to ensure that the rotating rod 301 can rotate on the pin 302. The retaining shaft 304 is located at the other end of the rotating rod 301 and is fixedly connected to the housing 1. The end cap 305 is fixedly located on the outside of the retaining shaft 304. A semi-circular groove 303 is opened at the end of the rotating rod 301, which can be engaged with the retaining shaft 304. The design of the end cap 305 prevents the rotating rod 301 from falling off the retaining shaft 304 and limits the rotation rod 301.

[0043] Both the inlet pipe 4 and the outlet pipe 5 include a pipe 9 and an insulation sleeve 10. The pipe 9 is located inside the insulation sleeve 10 and is sealed to the switch 2. The insulation sleeve 10 is made of polyurethane material.

[0044] The design of installing an insulation jacket 10 on the outside of pipe 9 can prevent the refrigerant from leaking into the air, significantly improving the refrigerant transmission rate. The insulation jacket 10 is made of polyurethane material, which has a low thermal conductivity and can play a good insulation role, avoiding the loss of cold energy and ensuring the refrigerant transmission effect.

[0045] In operation, the following steps are taken: First, the insulation sleeve 10 is placed over the outside of the pipe 9. Then, the input ends of the inlet pipe 4 and the outlet pipe 5 are connected to the inlet and outlet of the housing 1. Next, the switch 2 is fixedly installed at the connection between the pipe 9 and the housing 1. Then, the inlet pipe 4 and the outlet pipe 5 are respectively inserted into the inlet groove 101 and the outlet groove 102, extending downwards through the vertical part to the horizontal part, passing through the double-pipe guide assembly 6 to the right. Then, the double-pipe guide assembly 6 is pushed to insert the inlet pipe 4 and the outlet pipe 5 into the corresponding horizontal parts of the inlet groove 101 and the outlet groove 102. Then, the output ends of the inlet pipe 4 and the outlet pipe 5 pass through the inlet channel 702 and the outlet channel 703 of the arc-shaped guide frame 7. After exiting the arc-shaped guide frame 7, the output ends of the pipes 9 on the inlet pipe 4 and the outlet pipe 5 are respectively connected to the inlet and outlet of the three-stage cascade equipment 8. At this point, the connection of the pipes 9 is completed. Then, the placement of the housing 1 and the equipment is determined according to the location of the equipment. Position the arc-shaped guide frame 7, move it until the inlet pipe 4 and outlet pipe 5 are taut, then push the double-pipe guide assembly 6 again to adjust the inlet pipe 4 and outlet pipe 5 to the vicinity of the nearest notch A103 and notch B104, and insert the inlet pipe 4 into notch A103 and the outlet pipe 5 into notch B104. Then adjust the position of the arc-shaped guide frame 7 again to taut the inlet pipe 4 and outlet pipe 5, and fix the arc-shaped guide frame 7 by inserting expansion screws to complete the wiring operation of the inlet pipe 4 and outlet pipe 5. When the position of the housing 1 or the three-stage cascade device 8 needs to be adjusted, the expansion screws can be pulled out or removed. After the position of the housing 1 or the three-stage cascade device 8 is determined, move the arc-shaped guide frame 7 and the double-pipe guide assembly 6 again to readjust the position of the inlet pipe 4 and outlet pipe 5, and repeat the above steps to fix the arc-shaped guide frame 7.

[0046] In summary, this utility model has a reasonable design, neat and beautiful wiring, safe and reliable operation, improved refrigerant transmission efficiency, avoided pipeline damage, extended pipeline service life, and expanded its application scope.
