Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a compression bag exhaust valve body. Background Technology

[0002] With the improvement of people's living standards and the limited living space, the demand for efficient use of storage space is becoming increasingly urgent, especially for people who travel frequently or need to store a lot of items. The problem of clothing, bedding and other items taking up space is becoming more and more prominent. Compression bags, as a storage tool that can effectively save space, can greatly reduce the volume of items by expelling air from the bag through the exhaust valve, making storage more compact. However, the existing compression bag exhaust valves still have certain defects in use.

[0003] For example, the compression bag sealing valve proposed in application number CN201820931595.6 has a column on the upper side of the valve base plate. The valve base plate and the column are connected through an air hole. A ring is provided on the inner wall of the upper opening of the air hole, and a raised ring is provided on the top surface of the ring. The lower side of the transverse portion of the silicone gasket is fitted with the raised ring. Multiple supporting ribs are provided around the lower opening of the air hole, and ribs are provided at two corresponding positions along the lower opening of the air hole. The ribs and multiple supporting ribs are all located on the lower side of the valve base plate. A ring is provided at the center of the air hole, and the ends of each supporting rib extend into the air hole and connect to the side of the ring. Silicone gasket... The longitudinal portion of the gasket penetrates the ring body, and the bottom end of the longitudinal portion has a protrusion with a volume larger than that longitudinal portion to limit the silicone gasket. The valve cover is tightly closed on the column body, and the transverse portion of the silicone gasket is fully pressed by the valve cover. In actual use, the sealing valve of the compression bag is sealed by the silicone gasket that moves flexibly inside the air port. However, in actual use, the silicone gasket is prone to shaking and displacement, which affects the sealing effect and reduces the sealing stability. At the same time, when connecting the sealing valve to the compression bag, relying solely on the connection between the valve base plate and one side of the compression bag cannot guarantee the sealing effect of the connection.

[0004] Therefore, we propose a compression bag exhaust valve body to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a compression bag exhaust valve body to solve the problems of reduced sealing effect and poor connection sealing effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compression bag exhaust valve body, including an air inlet pipe,

[0007] An inner connecting piece is fixedly installed on the outer ring of the bottom end of the vent pipe, and a support plate is fixedly installed on the bottom of the inner connecting piece. An outer sleeve is fitted on the outer ring of the vent pipe, and an outer connecting piece is fixedly installed on the outer ring of the bottom end of the outer sleeve. A sealing ring is fixedly installed on the top surface of the inner connecting piece and the bottom surface of the outer connecting piece.

[0008] A positioning ring is fixedly installed on the inner ring of the vent pipe, and a telescopic sealing mechanism is installed inside the positioning ring. A sealing plug is fixedly installed on the top of the telescopic sealing mechanism.

[0009] A connecting pipe is fixedly installed on the top of the sealing plug, and a linkage opening mechanism is connected between the connecting pipe and the vent pipe.

[0010] The outer ring of the outer sleeve is threaded with a sealing cap, and a stop is fixedly installed at the bottom center of the sealing cap.

[0011] Preferably, the telescopic sealing mechanism includes a connecting seat installed on the inner ring of the positioning ring, a limiting ring fixedly connected to the inner side of the connecting seat, a movable rod slidably passing through the middle of the limiting ring, a base plate fixedly installed at the bottom end of the movable rod, a return spring sleeved on the outer ring of the movable rod between the base plate and the limiting ring, and a sealing plug fixedly connected to the top end of the movable rod.

[0012] Preferably, the connecting seats are distributed at equal angles between the positioning ring and the limiting ring, and the movable rod and the base plate are telescopically connected to the limiting ring by a return spring.

[0013] The above-mentioned structural design facilitates the use of the telescopic sealing mechanism to raise and lower the sealing plug, thereby facilitating the opening and closing of the positioning ring. This allows for venting during opening and sealing during closing, improving the sealing effect.

[0014] Preferably, a fitting ring is fixedly installed on the outer side of the bottom surface of the sealing plug, and a mating groove is provided on the top surface of the positioning ring, the mating groove being movably engaged with the fitting ring.

[0015] The above-mentioned structural design facilitates the sealing effect and limits the connection between the sealing plug and the positioning ring by utilizing the matching connection of the fitting ring and the mating groove, thus preventing shaking and displacement.

[0016] Preferably, the linkage opening mechanism includes a linkage seat fixedly installed inside the connecting pipe, a slide seat is attached to the inner side of the linkage seat, a slide seat is fixedly installed on the inner ring of the vent pipe, a slider is slidably connected inside the slide seat, and the slider is slidably connected to the inner side of the linkage seat.

[0017] Preferably, the linkage seat is set at equal angles on the inner side of the connecting pipe, and the slider is set in a trapezoidal structure.

[0018] The above-mentioned structural design facilitates the compression of the linkage opening mechanism by connecting the suction port and the vent pipe, thereby causing the linkage opening mechanism to drive the connecting pipe and the sealing plug to rise, thus enabling the positioning ring to open and achieve the venting operation. At the same time, when the suction port and the vent pipe are separated, the sealing plug can automatically reset and close, improving the convenience of sealing operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the exhaust valve body of the compression bag;

[0020] 1. The vent tube can be glued to the outer tube, which facilitates a tight fit between the inner and outer connecting pieces and the compression bag body on both sides. At the same time, the sealing ring can further improve the connection and sealing between the exhaust valve body and the compression bag body. The positioning ring, together with the lifting and lowering of the movable rod, can drive the sealing plug to extend and retract to seal and open the positioning ring, which is conducive to exhaust and sealing and improves the ease of use of the compression bag exhaust valve body.

[0021] 2. When the sealing plug seals the positioning ring, it works with the fitting ring and the mating groove to further improve the sealing effect of the compression bag exhaust valve body. When the air inlet is inserted into the air pipe, it will squeeze the slider, which will cause the slider to work with the linkage seat to open the sealing plug. It can also automatically seal when the suction port is pulled out, which improves the ease of use of the compression bag exhaust valve body. Furthermore, when the sealing cover is connected to the outer sleeve, the abutment can squeeze and position the sealing plug, which improves the sealing effect. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a compression bag exhaust valve body, including an air pipe 1, an inner connecting piece 2 fixedly installed on the outer ring of the bottom end of the air pipe 1, a support plate 3 fixedly installed on the bottom of the inner connecting piece 2, an outer sleeve 4 sleeved on the outer ring of the air pipe 1, an outer connecting piece 5 fixedly installed on the outer ring of the bottom end of the outer sleeve 4, and a sealing ring 6 fixedly installed on the top surface of the inner connecting piece 2 and the bottom surface of the outer connecting piece 5.

[0030] The design of the above structure allows for the following steps when installing the exhaust valve body and the compression bag body: First, the vent pipe 1 is passed through the mounting hole on the compression bag body, and the top surface of the inner connecting piece 2 is fitted against the inner side of the compression bag body. Then, the outer sleeve 4 is fitted onto the outer ring of the vent pipe 1, and the bottom surface of the outer connecting piece 5 is fitted against the outer side of the compression bag body. Next, the inner connecting piece 2 and the outer connecting piece 5 are glued to the compression bag body, and the vent pipe 1 and the outer sleeve 4 are glued together simultaneously to complete the installation. The sealing ring 6 effectively seals the connection between the inner connecting piece 2 and the outer connecting piece 5 and the compression bag body.

[0031] A positioning ring 7 is fixedly installed on the inner ring of the vent pipe 1. A telescopic sealing mechanism is installed inside the positioning ring 7. A sealing plug 13 is fixedly installed on the top of the telescopic sealing mechanism. The movable rod 10 and the base plate 11 are telescopically connected to the limiting ring 9 through a return spring 12. The telescopic sealing mechanism includes a connecting seat 8 installed on the inner ring of the positioning ring 7. The limiting ring 9 is fixedly connected to the inner side of the connecting seat 8. The connecting seats 8 are distributed at equal angles between the positioning ring 7 and the limiting ring 9. The movable rod 10 slides through the middle of the limiting ring 9. The base plate 11 is fixedly installed on the bottom end of the movable rod 10. A return spring 12 is sleeved on the outer ring of the movable rod 10 between the base plate 11 and the limiting ring 9. The movable rod 10 and the base plate 11 are telescopically connected to the limiting ring 9 through the return spring 12. The top of the movable rod 10 is fixedly connected to the sealing plug 13.

[0032] The above structure is designed so that when the connecting pipe 16 and the sealing plug 13 are lifted by the linkage opening mechanism, the sealing plug 13 will drive the movable rod 10 and the base plate 11 to rise synchronously, and the rise of the base plate 11 will cooperate with the limit ring 9 to compress the reset spring 12.

[0033] When the venting is finished, the return spring 12 can push the base plate 11, the movable rod 10 and the sealing plug 13 to descend and reset, and cause the sealing plug 13 to drive the fitting ring 14 to match the mating groove 15 on the top surface of the positioning ring 7, thereby facilitating the sealing plug 13 to seal the positioning ring 7 and improving the convenience of the sealing operation. The connecting seat 8 can provide a stable connection between the limiting ring 9 and the positioning ring 7.

[0034] A connecting pipe 16 is fixedly installed on the top of the sealing plug 13. A linkage opening mechanism is connected between the connecting pipe 16 and the vent pipe 1. The linkage opening mechanism includes a linkage seat 17 fixedly installed inside the connecting pipe 16. The linkage seat 17 is set at an equal angle on the inner side of the connecting pipe 16. A slide seat 18 is fitted and connected to the inner side of the linkage seat 17. The inner ring of the vent pipe 1 is fixedly installed with the slide seat 18. A slider 19 is slidably connected inside the slide seat 18. The slider 19 is set in a trapezoidal structure. The slider 19 is slidably connected to the inner side of the linkage seat 17. A sealing cap 20 is threaded on the outer ring of the outer sleeve 4. A stop post 21 is fixedly installed at the bottom center of the sealing cap 20.

[0035] The design of the above structure allows the sealing cap 20 to be rotated and separated from the outer sleeve 4 during venting. At this time, the abutment 21 releases the compression and positioning of the sealing plug 13 and the connecting pipe 16. Then, the suction port is inserted into the vent pipe 1, which then compresses the slider 19, causing the slider 19 to slide inward inside the slide seat 18. This causes the linkage seat 17, the connecting pipe 16, and the sealing plug 13 to rise, thereby opening the positioning ring 7 to achieve venting. When the suction port is pulled out, the telescopic sealing mechanism resets the sealing plug 13, causing the connecting pipe 16 and the linkage seat 17 to descend, and causing the slider 19 to reset inside the slide seat 18 to achieve sealing.

[0036] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
