Description

Technical Field

[0001] The present invention relates to the technical field of refrigerant storage, in particular to a refrigerant storage device. Background Art

[0002] The refrigerant absorbs heat from the cooling medium (water or air, etc.) in the evaporator and vaporizes, and transfers heat to the surrounding air or water in the condenser to condense. Through this cycle, the refrigerant can continuously absorb heat from the low-temperature object and discharge it to the high-temperature object, thereby achieving a cooling effect.

[0003] When the existing storage device positions and fixes the refrigerant tank, there is a device that uses its own gravity to achieve positioning and clamping. However, it relies on its own gravity to achieve positioning and clamping. However, during the removal stage, the clamping component that is in contact with the refrigerant tank cannot move longitudinally with the refrigerant tank. This causes the refrigerant tank to generate friction with the clamping component for a distance during the removal process. Especially during the removal process, due to the existence of friction, it will be very difficult.

[0004] Based on this, the invention discloses a refrigerant storage device. Summary of the invention

[0006] To achieve the above object, the present invention provides a refrigerant storage device, which includes a storage box, a storage cover is arranged on one side of the top of the storage box, and a plurality of groups of support components are evenly arranged in a matrix at the bottom of the storage box;

[0008] Several groups of mounting plates are arranged in the storage box along the length direction of the support rod, and adjustment components corresponding to the support components are arranged on the mounting plates. The support rod passes through the adjustment components, and several groups of clamping components are evenly arranged around the center of the circle in the adjustment components. The support rod rotates through the adjustment components to drive several groups of clamping components to form a circular structure with adjustable radius.

[0009] Preferably, the rotating assembly includes a mounting post, which is fixedly connected to the mounting plate, and the mounting post is provided with two spiral grooves with the same rotation direction, and a ball is slidably connected in the spiral groove, and the ball is rotatably connected to the lower end inner wall of the rotating cylinder, and a sliding cavity adapted to the mounting post is provided in the rotating cylinder, and a first spring is provided at the bottom end of the rotating cylinder, and the first spring is sleeved on the outside of the mounting post, and one end of the first spring is fixedly connected to the bottom end of the rotating cylinder, and the other end is fixedly connected to the mounting plate, and in an initial state, the bottom end of the rotating cylinder is located at the top end of the mounting post.

[0010] As a further improvement of the present technical solution, the first rotating disk is fixedly connected to the rotating cylinder, the first supporting disk is rotatably connected to the top of the rotating cylinder, the first supporting disk is fixedly connected to the second supporting disk, and the second supporting disk is provided with a groove adapted to the refrigerant tank.

[0011] As a further improvement of the present technical solution, the adjustment assembly includes a fixed plate, which is fixedly connected to the bottom of the mounting plate, and the fixed plate is provided with a guide groove adapted to the support rod, and a second rotating plate is arranged on the fixed plate, and the support rod passes through the guide groove and is fixedly connected to the second rotating plate, and the fixed plate is also provided with a second sliding groove corresponding to the clamping assembly, and the second rotating plate is provided with an inclined groove corresponding to the clamping assembly.

[0012] As a further improvement of the present technical solution, the clamping assembly includes a clamping plate, which has an arc-shaped structure. A push rod is fixedly connected to the side of the clamping plate away from the center of the circle. The push rod is slidably connected in the second slide groove. A first slide rod is fixedly connected to the push rod, and the first slide rod is slidably connected in the inclined groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the refrigerant storage device, by setting a matrix-type uniformly arranged support component, the mounting plate, the first slide groove and the support rod and other structures in each component can realize the preliminary support and pre-positioning of the refrigerant tank. When the refrigerant tank is placed on the support component, its gravity pushes the support rod to slide and drives the first rotating disk to rotate (realized by the cooperation of the spiral groove and the ball of the rotating component), which is conducive to realizing the rotation action without additional power, and provides a power source for the subsequent adjustment of the clamping component, thereby saving complex structures and driving sources; secondly, the rotation of the support rod is transmitted to the clamping component through the adjustment component (including the fixed plate, the guide groove, the second rotating disk and the inclined groove), and the clamping component (including the clamping plate, the push rod, the first slide rod, etc.) is driven by the rotation of the support rod to form a circular structure with an adjustable radius to adapt to refrigerant tanks of different radii. This linkage design facilitates the pre-positioning clamping of the refrigerant tank and improves the stability and flexibility of storage.

[0018] 2. In the refrigerant storage device, the rubber pad slidingly arranged on the clamping plate can first contact the refrigerant tank when the refrigerant tank is placed, playing a pre-positioning role. When the storage cover is closed, the refrigerant tank is further moved down, and the rubber pad slides in the third slide groove through the second slide bar to further clamp the refrigerant tank. The material and design of the rubber pad are conducive to protecting the appearance of the refrigerant tank during the clamping process, while meeting certain deformation requirements and ensuring that the clamping force is moderate; secondly, during the closing process of the storage cover, the refrigerant tank is further pressed down, and the clamping assembly and the rubber pad are synchronously brought together to achieve the final positioning and fixation of the refrigerant tank. When the storage cover is opened, with the help of the spring, the refrigerant tank and the clamping assembly will have a certain upward and away movement, and the refrigerant tank can be taken out It can move up with the rubber pad, and the clamping force on the refrigerant tank will be reduced during the upward movement, which is convenient for taking out the refrigerant tank, which is conducive to the natural separation of the refrigerant tank from the positioning and fixation when the cover is opened, and the convenient operation of positioning and fixation is achieved when the cover is closed.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The existing refrigerant storage device that realizes positioning and clamping by its own gravity is unstable. If the clamping force is increased, the refrigerant tank will be worn. At the same time, it will cause greater friction between the clamping component and the refrigerant tank, making it more difficult to remove.

[0035] To this end, the present invention provides a refrigerant storage device, see Figure 1-Figure 3 As shown, it comprises a storage box 1, a storage cover 2 is arranged on one side of the top of the storage box 1, and a plurality of groups of support components 6 are evenly arranged in a matrix at the bottom of the storage box 1;

[0036] Among them, see Figure 3 As shown, the support assembly 6 includes a mounting plate 61, a first annular slide groove 62 is provided on the mounting plate 61, two support rods 63 are symmetrically slidably arranged in the first slide groove 62, a first rotating plate 64 is slidably arranged on the support rod 63, the first rotating plate 64 is arranged on the rotating assembly 65, one end of the rotating assembly 65 is fixed on the mounting plate 61, and the other end passes through the first rotating plate 64 and is rotatably arranged with a first support plate 66, the first support plate 66 moves downward and drives the first rotating plate 64 to rotate through the rotating assembly 65;

[0037] For details, see Figure 4 As shown, the rotating assembly 65 includes a mounting column 651, which is fixedly connected to the mounting plate 61. The mounting column 651 is provided with two spiral grooves 652 with the same rotation direction. The spiral grooves 652 are slidably connected with a ball 653. The ball 653 is rotatably connected to the inner wall of the lower end of the rotating cylinder 654. The rotating cylinder 654 is provided with a sliding cavity adapted to the mounting column 651. The bottom end of the rotating cylinder 654 is provided with a first spring 655, which is sleeved on the mounting column 651. Outside the column 651, one end of the first spring 655 is fixedly connected to the bottom end of the rotating cylinder 654, and the other end is fixedly connected to the mounting plate 61. In the initial state, the bottom end of the rotating cylinder 654 is located at the top of the mounting column 651; secondly, the first rotating disk 64 is fixedly connected to the rotating cylinder 654, and the first supporting disk 66 is rotatably connected to the top of the rotating cylinder 654. The first supporting disk 66 is fixedly connected to the second supporting disk 67, and the second supporting disk 67 is provided with a groove adapted to the refrigerant tank.

[0038] It can be seen that the support assembly 6 with a uniform matrix layout can realize the supporting pre-positioning effect of the refrigerant tank (the effect of the groove), and at the same time, the downward movement of the gravity of the refrigerant tank can drive the rotation of the first rotating disk 64, and the rotation of the first rotating disk 64 can be realized without the need for additional action. The reason for this design is to utilize the gravity of the refrigerant tank to realize the rotation action, and to provide a power source for further pre-clamping and positioning with the help of the gravity of the refrigerant tank in the following text. This saves effort and saves complex structure and driving source.

[0039] For further information, see Figure 1 and Figure 2 As shown, several groups of mounting plates 3 are arranged in the storage box 1 along the length direction of the support rod 63, and an adjusting assembly 4 corresponding to the supporting assembly 6 is arranged on the mounting plate 3. The support rod 63 passes through the adjusting assembly 4, and several groups of clamping assemblies 5 are evenly arranged around the center of the circle in the adjusting assembly 4. The support rod 63 rotates through the adjusting assembly 4 to drive the several groups of clamping assemblies 5 to form a circular structure with adjustable radius; that is, the rotational force of the support rod 63 brought about by the downward movement of the refrigerant tank can synchronously realize the adjustment of the clamping radius size of the clamping assembly 5, so that it can adapt to the radius of the refrigerant tank, thereby realizing the pre-positioning clamping of the refrigerant tank.

[0040] Among them, see Figure 5 and Figure 6 As shown, the adjustment component 4 includes a fixed plate 41, which is fixedly connected to the bottom of the mounting plate 3. The fixed plate 41 is provided with a guide groove 42 adapted to the support rod 63. A second rotating plate 44 is provided on the fixed plate 41. The support rod 63 passes through the guide groove 42 and is fixedly connected to the second rotating plate 44. The fixed plate 41 is also provided with a second sliding groove 43 corresponding to the clamping component 5, and the second rotating plate 44 is provided with an inclined groove 45 corresponding to the clamping component 5.

[0041] For further information, see Figure 7 and Figure 8 As shown, the clamping assembly 5 includes a clamping plate 51, which is in an arc-shaped structure. A push rod 52 is fixedly connected to one side of the clamping plate 51 away from the center of the circle. The push rod 52 is slidably connected in the second slide groove 43. A first slide rod 53 is fixedly connected to the push rod 52. The first slide rod 53 is slidably connected in the inclined groove 45.

[0042] Furthermore, a rubber pad 56 is slidably provided on one side of the clamping plate 51 away from the top rod 52, and a third slide groove 54 is opened in the center position of the clamping plate 51, and a second slide rod 55 is slidably connected in the third slide groove 54. A second spring 57 is provided at the bottom end of the second slide rod 55, and the top end of the second slide rod 55 is fixedly connected to the rubber pad 56, one end of the second spring 57 is fixedly connected to the second slide rod 55, and the other end is fixedly connected to the inner wall of the bottom end of the third slide groove 54. The design of the rubber pad 56 here can protect the appearance of the refrigerant tank and prevent it from being scratched during the clamping process. Secondly, in the present invention, when the refrigerant tank is placed on the second support plate 67, relying on the gravity of the refrigerant tank, the rubber pad 56 has been fitted with the refrigerant tank, so it can play a pre-positioning role, but it cannot achieve a larger positioning and clamping effect. , and then when the storage cover 2 is closed, the refrigerant tank is further pressed down, and at this time, the rubber pad 56 is slidably connected to the third slide groove 54 by the second slide bar 55, so that the rubber pad 56 and the refrigerant tank can move downward synchronously in a mutually fitting manner, and at the same time, the rubber pad 56 can continuously increase the positioning and clamping force of the refrigerant tank during the downward movement, and the material of the rubber pad 56 can meet a certain deformation requirement. Therefore, it can be concluded that the rubber pad 56 realizes the pre-positioning and clamping of the refrigerant tank, and at the same time, it can increase the positioning and clamping force of the refrigerant tank during the further downward movement of the refrigerant tank, and this process will not affect the position of the clamping plate 51, because in the process of closing the storage cover 2, the refrigerant tank drives the rubber pad 56 to move downward. In this process, if the structural design of the rubber pad 56 is not Figure 8 As shown in , the rubber pad 56 that is in contact with the refrigerant tank cannot move downward, so that the rubber pad 56 cannot be further brought closer, and the force required to further increase the positioning and clamping of the refrigerant tank cannot be met.

[0043] In addition, after the rotating cylinder 654 moves downward, the height of the refrigerant tank satisfies the storage cover 2 to complete the box cover with the storage box 1, and at this time the clamping assembly 5 is completely in contact with the refrigerant tank, and the top of the refrigerant tank is in contact with the bottom of the storage cover 2. It should be noted that when the refrigerant tank reaches a balance with the first spring 655 under the action of gravity, that is, the rotating cylinder 654 no longer moves downward, the rubber pad 56 is in contact with the refrigerant tank, and the top of the refrigerant tank is slightly higher than the top edge of the storage box 1. This provides room for the refrigerant tank to move further downward during the closing process of the storage cover 2, and can also simultaneously achieve further approach of the rubber pad 56, thereby increasing the positioning and clamping force of the refrigerant tank.

[0044] In addition, the curvature of the spiral groove 652 satisfies the first sliding rod 53 sliding from the head end to the tail end along the inclined groove 45 .

[0045] Working principle:

[0046] In the initial state, due to the action of the first spring 655, the rotating cylinder 654 is at the top position of the mounting column 651, that is, the ball 653 is located at the starting position of the spiral groove 652. At this time, the plurality of groups of clamping plates 51 in the longitudinal direction of the support rod 63 are all at the maximum radius position, that is, the first slide bar 53 is at the end of the inclined groove 45 farthest from its center.

[0047] Then, the refrigerant tank is directly moved along the longitudinal direction of the support rod 63, that is, sequentially from top to bottom through the center of the circular structure formed by each group of clamping components 5, until the bottom of the refrigerant tank is stuck in the groove of the second support plate 67. At this time, the existence of the second support plate 67 can have a pre-stabilizing effect on the refrigerant tank. Then, under the action of the gravity of the refrigerant tank itself, the second support plate 67 will be pressed down, and the downward movement of the second support plate 67 will drive the rotating cylinder 654 to move downward. At this time, the ball 653 on the rotating cylinder 654 will slide along the spiral structure of the spiral groove 652. Since the spiral groove 652 is rotatably connected to the rotating cylinder 654, the ball 653 on the rotating cylinder 654 will slide along the spiral structure of the spiral groove 652. The inner wall of the top of the cylinder 654, and then the spiral structure of the spiral groove 652 will cause the rotating cylinder 654 to rotate, and in this process, the ball 653 can reduce the friction, which helps to move the rotating cylinder 654 downward, thereby causing the rotating cylinder 654 to rotate, and the rotation of the rotating cylinder 654 drives the first rotating disk 64 to rotate, and further drives the support rod 63 to slide in the first sliding groove 62; at the same time, the support rod 63 will also slide in the guide groove 42, because the fixed disk 41 is fixed on the mounting plate 3, and therefore the guide groove 42 can maintain the stability of the fixed disk 41 without affecting the rotation of the support rod 63.

[0048] When the support rod 63 rotates, it will drive the several groups of second rotating disks 44 fixedly connected to the entire support rod 63 in the longitudinal direction to rotate, so that the first sliding rod 53 slides along the inclined groove 45 on the second rotating disk 44. Due to the arc-shaped structure of the inclined groove 45, the first sliding rod 53 can be pushed to drive the push rod 52 to slide along the second sliding groove 43, that is, the radial direction of the fixed disk 41 from the outside to the inside, so that the several groups of clamping plates 51 will also gather together, thereby realizing the support and fixation of the refrigerant tank. At this time, the refrigerant tank is pre-positioned and fixed by its own gravity. However, the refrigerant tank will still be shaken when there is external force or transfer, because at this time, the rubber pad 56 on the clamping plate 51 is in contact with the refrigerant tank but not clamped. However, when the refrigerant tank is placed in the center of the prototype structure formed by the several clamping plates 51, it has actually been pre-positioned and fixed, so it will not affect the subsequent placement of other refrigerant tanks.

[0049] When all positions in the entire storage box 1, that is, positions corresponding to several groups of support assemblies 6, are filled with refrigerant cans, the storage cover 2 can be closed. Before the storage cover 2 is closed, the top of the refrigerant can actually exceeds the top edge of the storage box 1, which means that the closing of the storage cover 2 will further squeeze several refrigerant cans to continue to move downward, thereby squeezing the second support plate 67 to continue to move downward. It is worth noting that the second support plate 67 and the first support plate 66 are rotatably connected to the rotating cylinder 654. Combined with the heavy weight of the refrigerant can, the downward movement of the second support plate 67 will not cause the rotation of the refrigerant can.

[0050] During the process of closing the storage cover 2 and the storage box 1, the refrigerant tank is driven to continue to move downward, which means that the rotating cylinder 654 continues to rotate. Therefore, in combination with the above process, a number of clamping plates 51 will continue to move closer to each other, thereby further squeezing and fixing the refrigerant tank. It is worth noting that when the refrigerant tank has been placed on the second support plate 67 by gravity, the rubber pad 56 has been in contact with the refrigerant tank. Therefore, when the refrigerant tank continues to move downward, the rubber pad 56 continues to squeeze the refrigerant tank driven by the clamping plate 51, which will cause the refrigerant tank to drive the rubber pad 56 to slide downward along the third slide groove 54. In this way, the refrigerant tank will slide down while the rubber pad 56 will further squeeze and fix the refrigerant tank at the same time. Therefore, the design of the rubber pad 56 sliding in the third slide groove 54 through the second slide rod 55 can play a role in pre-fixing the refrigerant tank when the refrigerant tank is placed in the second support plate 67. At the same time, when the storage cover 2 is closed to finally position and fix the refrigerant tank, it can also play a role in strengthening the clamping without affecting the downward movement of the refrigerant tank in this process, so that the storage cover 2 can be closed. After the storage cover 2 is closed and fixed, the top of the refrigerant tank is tightly against the inner wall of the storage cover 2, that is to say, the refrigerant tank has a certain tendency to move upward, so that it can be ensured that after the storage cover 2 is closed, the rubber pad 56 can be tightly clamped and the refrigerant tank is positioned and fixed.

[0051] Later, when preparing to unload, combined with the above-mentioned tendency of the refrigerant tank to move upward after the storage cover 2 is closed, after opening the storage cover 2, the second spring 57 and the first spring 655 will cause the refrigerant tank to move upward to a certain extent, and at the same time, several groups of clamping plates 51 will also move away from each other (combined with the above-mentioned working principle, it can be deduced that the upward movement of the rotating cylinder 654 will cause the second rotating disk 44 to rotate in the opposite direction, thereby causing the push rod 52 to move in the opposite direction along the second slide groove 43), so the positioning restriction on the refrigerant tank can be naturally released, so that the refrigerant tank can be easily taken out of the storage box 1 to complete the transfer and unloading (during the removal process, as the squeezing of the refrigerant tank on the second support disk 67 is reduced, the rotating cylinder 654 will move upward under the action of the first spring 655).

[0052] In summary, the gravity of the refrigerant tank drives several groups of rubber pads 56 to move closer to each other to achieve pre-positioning and fixing. After that, after the storage cover 2 is closed, the rubber pads 56 are further moved downward and closer to achieve the final positioning and fixing of the refrigerant tank. When the storage cover 2 is opened, the squeezing and positioning of the refrigerant tank are released, and several rubber pads 56 will also lose their large clamping force on the refrigerant tank. Then, when the refrigerant tank is pulled out, several rubber pads 56 will move up a distance synchronously with the refrigerant tank, and then begin to gradually reduce the clamping force on the refrigerant tank until it just fits with the refrigerant tank. Then, under the action of the first spring 655, they move away from each other, and the refrigerant tank can be easily taken out, thereby effectively solving the instability of the existing refrigerant storage device that achieves positioning and clamping by its own gravity. In addition, if the clamping force is increased, the refrigerant tank will be worn, and at the same time, there will be greater friction between the clamping component and the refrigerant tank, which will make the removal more troublesome.
