[0027] In order to make the above purpose, feature and advantage of the utility model more obvious and easy to understand, the following specific embodiment of the utility model is explained in detail with the drawing of specification.

[0028] In the following description, a lot of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0029] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0030] Embodiment 1

[0031] Reference Figures 1-8 For the first embodiment of the present application, the embodiment provides a compressed air storage tank with good sealing, which comprises a main body assembly 100, comprising a tank body 101 and a gas release valve 102, the gas release valve 102 is movably connected to one side of the tank body 101, the tank body 101 is provided with a vent column 101-1, and the number of the vent column 101-1 is two.

[0032] When the pressure in the compressed air system exceeds the set safety pressure value, the gas release valve 102 is automatically opened, and part of the compressed air is rapidly released, so that the system pressure is reduced to the safety range, preventing the equipment from being damaged due to excessive pressure, and ensuring the safety of the system and personnel, which is the prior art, and the present application will not be described in detail, and those skilled in the art can clearly understand the working principle.

[0033] The sealing assembly 200 is arranged on the tank body 101 and comprises a connecting piece 201, the connecting piece 201 comprises a connecting block 201a, a fixed block 201b and a locking block 201c, the connecting block 201a is located on one side of the vent column 101-1, the connecting block 201a is provided with an annular groove 201a-1, the vent column 101-1 is inserted into the annular groove 201a-1, the fixed block 201b is fixed on the tank body 101, the fixed block 201b is provided with a sliding groove 201b-1, the locking block 201c is slidably arranged in the sliding groove 201b-1, the connecting block 201a is provided with a locking groove 201a-2, and the locking block 201c can be clamped with the locking groove 201a-2.

[0034] The connecting piece 201 is arranged for connecting the tank body 101 and the pipeline. The connecting block 201a is arranged for connecting the gas storage tank, the air compressor, the gas using equipment and other related components into a complete system. The connecting block 201a is provided with a connecting port 201h at the top. The connecting port 201h is provided with an air passage in the middle. The air in the tank body 101 can be communicated with the air outside the tank body through the air passage on the connecting port 201h. The connection with other equipment is the prior art. Therefore, the present scheme will not be described in detail. The working principle can be clearly understood by those skilled in the art. The connecting block 201a is connected with the fixing block 201b through the cooperation of the locking block 201c and the locking groove 201a-2, so as to stably install the connecting block 201a on the tank body 101.

[0035] The number of the fixing block 201b is two. When installing, the connecting block 201a is placed between the two fixing blocks 201b, and a downward pushing force is applied to the connecting block 201a.

[0036] The sealing assembly 200 further comprises a sealing piece 202 arranged on the connecting block 201a, which comprises a first sealing ring 202a, a second sealing ring 202b, an arc-shaped plate 202c, a push plate 202d and a stress plate 202e. The first sealing ring 202a is fixed on the inner wall of the annular groove 201a-1. The second sealing ring 202b is fixed on the first sealing ring 202a. The arc-shaped plate 202c is arranged on one side of the second sealing ring 202b. The push plate 202d is fixed on one end of the arc-shaped plate 202c. The stress plate 202e is located on one side of the push plate 202d.

[0037] Through the arrangement of the sealing piece 202, the part where the connecting block 201a is connected with the air passage column 101-1 has good sealing performance. When the connecting block 201a is pushed downward between the two fixing blocks 201b, the first sealing ring 202a will be in contact with the top end face of the air passage column 101-1. The first sealing ring 202a and the second sealing ring 202b both have a certain deformation capacity. When the connecting block 201a is pressed downward, the first sealing ring 202a will be compressed, so as to ensure that the first sealing ring 202a is tightly attached to the top of the air passage column 101-1.

[0038] The bottom of the second sealing ring 202b is inclined. When the connecting block 201a is installed, the inclined part of the second sealing ring 202b will first contact the air passage column 101-1. The air passage column 101-1 extrudes the inclined surface of the second sealing ring 202b, so as to facilitate the insertion of the second sealing ring 202b into the air passage column 101-1.

[0039] When the connecting block 201a is installed, the second sealing ring 202b needs to be ensured to enter the venting column 101-1 completely, and then the connecting block 201a is continuously pushed downwards to seal the connecting position of the connecting block 201a and the venting column 101-1 through the cooperation of the first sealing ring 202a and the second sealing ring 202b.

[0040] When the air pressure in the tank body 101 gradually increases and does not exceed the predetermined air pressure peak value, under the action of the atmospheric pressure, the air in the tank body 101 will have a tendency to flow outwards, and if the sealing of the first sealing ring 202a and the second sealing ring 202b is insufficient, the air in the tank body 101 will gush out from the venting column 101-1, in the process, the force receiving plate 202e will be pushed upwards by the gushing air in the tank, and then push the push plate 202d to move towards the second sealing ring 202b, and then make the arc-shaped plate 202c extrude the second sealing ring 202b, so that the second sealing ring 202b is deformed to extrude the inner wall of the venting column 101-1, thereby improving the sealing performance and avoiding the leakage of the air in the tank body 101.

[0041] Embodiment 2

[0042] With reference to Figures 1-8 As the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0043] Specifically, one end of the push plate 202d is inclined, and the top of the force receiving plate 202e is correspondingly inclined, and the inclined surface of the push plate 202d is in contact with the inclined surface of the force receiving plate 202e.

[0044] Through the inclined arrangement, when the air in the tank body 101 has a tendency to gush out from the venting column 101-1, the gushing air will apply an upward pushing force to the force receiving plate 202e, so that the force receiving plate 202e moves upwards, and the inclined surface of the force receiving plate 202e extrudes the inclined surface of the push plate 202d, so that the push plate 202d moves towards the second sealing ring 202b, and the second sealing ring 202b is deformed to extrude the inner wall of the venting column 101-1, thereby improving the sealing performance.

[0045] Specifically, the arc-shaped plate 202c is provided with a sliding groove 202c-1, the sliding groove 202c-1 is provided with an expansion plate 202f, and the sliding groove 202c-1 is provided with two expansion plates 202f, and one end of the expansion plate 202f is fixedly provided with a first spring 202g.

[0046] The telescopic plates 202f are arranged to ensure that the second sealing ring 202b can be pushed to ensure air tightness. There are four groups of arc-shaped plates 202c. Adjacent two arc-shaped plates 202c are always in close contact with each other through the telescopic plates 202f. When the push plate 202d pushes the arc-shaped plate 202c to extrude the second sealing ring 202b, the second sealing ring 202b will be deformed, and the radius of the inner circle will increase. At this time, under the pushing of the first spring 202g, the length of the telescopic plate 202f extending out of the sliding groove 202c-1 will be longer, and the telescopic plates 202f are still in contact with each other, thereby ensuring the sealing effect of the second sealing ring 202b.

[0047] Specifically, the locking block 201c is fixed at one end with the second spring 201d, and the other end of the second spring 201d is fixed with the inner wall of the sliding groove 201b-1. The locking block 201c is fixed at one end with the pull plate 201e.

[0048] The second spring 201d continuously applies a pushing force to the locking block 201c to ensure that the locking block 201c can always be engaged with the locking groove 201a-2. The pull plate 201e is used to unlock the engagement of the locking block 201c and the locking groove 201a-2, so that the connecting block 201a is separated from the fixed block 201b, and the connecting block 201a is detached from the tank body 101.

[0049] Specifically, the locking block 201c is inclined at one end, and the shape of the locking groove 201a-2 corresponds to the locking block 201c, and the number of the locking groove 201a-2 is multiple.

[0050] Through the inclined arrangement, when the connecting block 201a is installed on the vent column 101-1, the inclined surface of the locking block 201c will first contact the bottom of the connecting block 201a. The connecting block 201a extrudes the inclined surface of the locking block 201c, so that the second spring 201d is compressed, and the locking block 201c moves into the sliding groove 201b-1, which does not affect the movement of the connecting block 201a to the vent column 101-1. When the locking block 201c and one of the locking grooves 201a-2 are coaxial, the second spring 201d is restored, and the locking block 201c is engaged with the locking groove 201a-2.

[0051] When the connecting block 201a is pressed, the first sealing ring 202a is compressed and deformed, and the connecting block 201a will move further downward. The inclined surface of the locking groove 201a-2 extrudes the inclined surface of the locking block 201c, and the second spring 201d is compressed again. At this time, the locking block 201c does not hinder the downward movement of the connecting block 201a. When the locking block 201c and another locking groove 201a-2 are coaxial, the two are engaged, and the right angle surface of the locking groove 201a-2 contacts the right angle surface of the locking block 201c, which hinders the separation of the connecting block 201a and the fixed block 201b. In this way, the connecting block 201a is stably installed on the tank body 101.

[0052] Specifically, a support block 202h is fixed to the inner wall of the annular groove 201a-1, a first moving groove 201f-1 is formed in the support block 202h, and a push plate 202d slides in the first moving groove 201f-1, one side of the push plate 202d is fixed with a support plate 202i, and one end of the support plate 202i is fixed with a third spring 202j.

[0053] The support block 202h is used to provide stable support for the push plate 202d, the support plate 202i has a certain deformation capacity, the third spring 202j is always in a compressed state, and a pushing force is generated on the support plate 202i, so that the push plate 202d extrudes the second sealing ring 202b, and the second sealing ring 202b is tightly attached to the inner wall of the air column 101-1.

[0054] When the stress plate 202e moves upward and pushes the push plate 202d to move closer to the second sealing ring 202b again, the support plate 202i is compressed and deformed, and does not hinder the movement of the push plate 202d.

[0055] Embodiment 3

[0056] Reference Figures 1-8 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.

[0057] Specifically, an auxiliary block 202k is fixed to the inner wall of the annular groove 201a-1, the auxiliary block 202k is provided with a second moving groove 202k-1, a stress plate 202e slides in the second moving groove 202k-1, one side of the stress plate 202e is fixed with an auxiliary plate 202m, and one side of the auxiliary plate 202m is fixed with a fourth spring 202n.

[0058] The auxiliary block 202k provides stable support for the stress plate 202e, and the fourth spring 202n applies an upward pushing force to the stress plate 202e, so that the push plate 202d does not move downward under the condition of no other external force, and at this time, the inclined surface of the push plate 202d is in contact with the inclined surface of the stress plate 202e.

[0059] Specifically, the bottom of the connecting block 201a is fixed with a rubber pad 201g.

[0060] The deformation force of the rubber pad 201g is smaller than that of the first sealing ring 202a, and the rubber pad 201g is arranged to avoid direct contact between the connecting block 201a and the tank body 101 when the connecting block 201a is subjected to a downward pushing force.

[0061] Specifically, the number of sealing assemblies 200 is two.

[0062] The two air columns 101-1 are respectively the gas outlet and the gas inlet of the tank body 101.

[0063] Specifically, the main component 100 also includes a support leg 103, which is fixed to the bottom of the tank body 101.

[0064] There are two support legs 103, which provide stable support for the tank body 101.

[0065] In use, place the connecting block 201a between the two fixed blocks 201b, ensuring that the second sealing ring 202b is fully inserted into the vent column 101-1. Then continue to push the connecting block 201a downwards. The inclined surface of the locking block 201c will first contact the bottom of the connecting block 201a. The connecting block 201a presses against the inclined surface of the locking block 201c, compressing the second spring 201d. The locking block 201c moves into the sliding groove 201b-1 without affecting the movement of the connecting block 201a toward the vent column 101-1. When the locking block 201c is in a coaxial position with one of the locking grooves 201a-2, the second spring 201d returns to its original position, and the locking block 201c and the locking groove 201a-2 will engage, thus initially locking the positions of the connecting block 201a and the fixed block 201b.

[0066] When the connecting block 201a is pressed down, the first sealing ring 202a is compressed and deformed, and the connecting block 201a will move further downward. The inclined surface of the locking groove 201a-2 will press against the inclined surface of the locking block 201c, and the second spring 201d will be compressed again. At this time, the locking block 201c will not hinder the downward movement of the connecting block 201a. When the locking block 201c and the other locking groove 201a-2 are in a coaxial position, the two engage, thereby stably installing the connecting block 201a onto the tank 101.

[0067] When the airtightness of the connection between the connecting block 201a and the vent column 101-1 decreases, the air inside the tank 101 will tend to escape from the gap between the vent column 101-1 and the connecting block 201a. The outward flow of gas will exert an upward thrust on the force plate 202e, causing the force plate 202e to move upward. The inclined surface of the force plate 202e will squeeze the inclined surface of the push plate 202d, causing the push plate 202d to move closer to the second sealing ring 202b, causing the second sealing ring 202b to deform and squeeze the inner wall of the vent column 101-1, thereby improving the sealing performance.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
