Description

Technical Field

[0001] The present application relates to the field of sealing equipment, and in particular to a sealing cover structure for an air compressor that is easy to load and unload. Background Art

[0002] An air compressor is a device used to compress gas, which is mainly composed of a main unit, an engine, an oil-gas separation barrel, a cooler and other components. Since the main unit of the air compressor needs to use lubricating oil to reduce component wear when compressing air, the air compressed by the main unit is actually mixed with lubricating oil, and an oil-gas separation barrel is needed to separate the lubricating oil from the compressed air. The oil filter in the oil-gas separation barrel needs to be replaced regularly to ensure the normal operation of the oil-gas separation barrel. Similarly, other accessories such as air filters also need to be replaced regularly.

[0003] In existing equipment, a loading and unloading port corresponding to the position of the accessory to be replaced is usually opened on the top cover of the air compressor to facilitate the replacement of accessories by staff; since the air compressor contains high-temperature and high-pressure gas, the loading and unloading port needs to be sealed after the accessories are replaced to improve the safety of the air compressor; currently, bolts are mainly used to fix the sealing cover on the loading and unloading port in the air compressor, but using this method, multiple bolts used for fixing need to be removed each time the accessories are replaced, and then manually installed after the replacement is completed, which is time-consuming and labor-intensive, and the bolts and sealing covers are easy to be lost during the replacement process.

[0004] Therefore, it is necessary to design a sealing cover structure for an air compressor that is convenient for loading and unloading air compressor accessories. Utility Model Content

[0023] Furthermore, the locking tongue is fixedly connected to the inner wall of the movable groove via a plurality of second elastic members.

[0024] Furthermore, a second contact surface is formed on the surface of the locking tongue.

[0025] Furthermore, a surface portion of the lock seat is concave and penetrates into the movable groove to form a driving groove, and a driving rod is arranged in the driving groove, and the driving rod is fixedly connected to the lock tongue.

[0026] Furthermore, a side of the cover plate away from the fixing seat is bent upward to form a bent portion.

[0027] Furthermore, a resisting portion is formed on the articulated arm, and a resisting plate is fixedly arranged on the fixed seat. When the articulated arm rotates to an angle α, the resisting portion can resist the resisting plate.

[0028] The value range of α is 120°-160°.

[0029] The beneficial effects of this application are:

[0030] 1. The cover can be opened after moving the lock tongue, which is convenient for loading and unloading air compressor accessories;

[0051] Specifically, a loading and unloading port 7 for loading and unloading accessories is provided on the housing 6 of the air compressor, and a cover plate 1 is provided at the loading and unloading port 7. A fixing seat 2 is fixedly installed on the housing 6 of the air compressor, and an articulated arm 3 is rotatably provided on the fixing seat 2. The articulated arm 3 is fixedly connected to the cover plate 1, so that the cover plate 1 can rotate relative to the fixing seat 2. The loading and unloading port 7 can be opened or closed by rotating the cover plate 1, and the problem of the cover plate 1 being lost due to misplacement by the staff after being opened can be avoided; the side of the cover plate 1 away from the fixing seat 2 is bent upward to form a bending portion 4. Since the cover plate 1 is closely attached to the housing 6, the setting of the bending portion 4 can facilitate the cover plate 1 to be lifted by hand;

[0052] The rubber ring 5 is fixedly arranged on the bottom surface of the cover plate 1. When the cover plate 1 is placed on the loading and unloading port 7, the rubber ring 5 can contact the shell 6 around the loading and unloading port 7. Since the air compressor contains high-temperature and high-pressure gas, the provision of the rubber ring 5 can improve the safety performance of the air compressor. The provision of the rubber ring 5 can also prevent the cover plate 1 from colliding with the shell 6 when the cover plate 1 is placed on the loading and unloading port 7 to generate abnormal noise.

[0053] A resistance portion 8 is formed on the articulated arm 3, and a resistance plate 9 is fixedly arranged on the fixed seat 2. When the articulated arm 3 rotates to an angle α10, the value of α10 is 120°, and the resistance portion 8 can resist the resistance plate 9, thereby fixing the cover plate 1. The setting of the resistance portion 8 and the resistance plate 9 can prevent the cover plate 1 from flipping over to the surface of the shell 6 and colliding with the shell 6.

[0054] The air compressor sealing cover structure that is easy to load and unload also includes a locking assembly 11. The locking assembly 11 is provided with two groups, which are respectively arranged on both sides of the loading and unloading port 7. The locking assembly 11 can fix the cover plate 1 on the housing 6 and press the cover plate 1 and the rubber ring 5 to achieve sealing;

[0055] Specifically, the lock assembly 11 includes a lock seat 12 fixedly arranged on the housing 6 of the air compressor and a lock tongue 13 arranged in the lock seat 12 and capable of moving relative to the lock seat 12; the surface portion of the lock seat 12 is concave to form a moving groove 14, and the lock tongue 13 is movably arranged in the moving groove 14; the top surface portion of the lock seat 12 is concave and penetrates into the moving groove 14 to form a telescopic groove 15, and a limiting block 16 is arranged in the telescopic groove 15, and the limiting block 16 can move relative to the telescopic groove 15, and the top surface portion of the lock tongue 13 is concave to form a first limiting groove 17 and a second limiting groove 18. Limiting groove 18, when the lock tongue 13 is moved to the first limiting groove 17 corresponding to the position of the telescopic groove 15, the limiting block 16 can be moved so that the limiting block 16 extends into the first limiting groove 17, at which time the lock tongue 13 is limited in the moving direction, and the lock tongue 13 is out of contact with the cover plate 1; when the lock tongue 13 is moved to the second limiting groove 18 corresponding to the position of the telescopic groove 15, the limiting block 16 can be moved so that the limiting block 16 extends into the second limiting groove 18 to limit the lock tongue 13, at which time the lock tongue 13 partially extends out of the moving groove 14 and contacts the cover plate 1, pressing the cover plate 1 against the housing 6;

[0056] A first abutment surface 19 is formed on the limit block 16. When the lock tongue 13 moves, the inner wall of the first limit groove 17 or the second limit groove 18 can abut against the first abutment surface 19, driving the limit block 16 to move upward to release the limit.

[0057] A telescopic shell 20 is fixedly arranged at a position corresponding to the top surface of the lock seat 12 and the telescopic groove 15, and a push rod 21 is arranged inside the telescopic shell 20. The bottom end of the push rod 21 is fixedly connected to the limit block 16, and the top end of the push rod 21 is inserted through the top wall of the telescopic shell 20 and arranged outside the telescopic shell 20. The end of the push rod 21 away from the limit block 16 is fixedly connected with a pull ring 22, and the pull ring 22 can facilitate manual pushing and pulling of the push rod 21; a first elastic member 23 is arranged inside the telescopic shell 20 and is sleeved on the outside of the push rod 21. The bottom end of the first elastic member 23 is fixedly connected to the limit block 16. The first elastic member The top of the first elastic member 23 is fixedly connected to the top wall of the telescopic shell 20; the first elastic member 23 is a spring. When the limit block 16 extends into the first limit groove 17 or the second limit groove 18, the first elastic member 23 is in a normal state. When the limit block 16 is completely moved into the telescopic groove 15, the first elastic member 23 is in a compressed state. Therefore, when the lock tongue 13 is moved so that the first limit groove 17 or the second limit groove 18 corresponds to the position of the telescopic groove 15, the limit block 16 can automatically extend into the first limit groove 17 or the second limit groove 18 under the drive of the first elastic member 23 to achieve limiting.

[0058] The lock tongue 13 is fixedly connected to the inner wall of the movable groove 14 by three second elastic members 24, and the second elastic member 24 is a spring; specifically, when the first limiting groove 17 corresponds to the position of the telescopic groove 15, the second elastic member 24 is in a compressed state, and when the second limiting groove 18 corresponds to the position of the telescopic groove 15, the second elastic member 24 is in a normal state; when the cover plate 1 needs to be locked, the pull ring 22 is pulled upward, and the limiting block 16 moves out of the first limiting groove 17, and the second elastic member 24 can push the lock tongue 13 to move, until it moves to the second limiting groove 18 corresponding to the telescopic groove 15, and the limiting block 16 automatically extends into the second limiting groove 18 under the action of the first elastic member 23 to achieve limiting;

[0059] More specifically, the surface portion of the lock seat 12 is concave and penetrates into the movable groove 14 to form three driving grooves 25, and a driving rod 26 is provided in the driving groove 25, and the driving rod 26 is fixedly connected to the lock tongue 13; the ends of the three driving rods 26 away from the lock tongue 13 are fixedly connected to a push plate 27; a second resistance surface 28 is formed on the surface of the lock tongue 13, and when the lock tongue 13 extends out of the movable groove 14, the second resistance surface 28 can squeeze the cover plate 1 and drive the cover plate 1 to be pressed downward, and when the bottom surface of the lock tongue 13 is higher than the top surface of the cover plate 1, the lock tongue 13 can press the cover plate 1; when the thrust of the second elastic member 24 is not enough to push the cover plate 1 downward, pushing the push plate 27 can help the lock tongue 13 to lock the cover plate 1.

[0060] The specific working principle is as follows: when it is necessary to load and unload the internal accessories of the air compressor, push the lock tongue 13 to unlock the cover plate 1. Since the first contact surface 19 is set on the limit block 16, the limit block 16 automatically moves upward when the lock tongue 13 is pushed. During the movement of the lock tongue 13, the limit block 16 automatically engages with the first limit groove 17 to achieve limit; insert a finger under the bending portion 4 of the cover plate 1 to lift the cover plate 1. When the cover plate 1 is opened and flipped to 120°, the contact portion 8 contacts the contact plate 9 to fix the cover plate 1, preventing the cover from being locked. 1 collides with the housing 6 of the air compressor; after the accessories of the air compressor are loaded and unloaded, the cover plate 1 is turned over to the loading and unloading port 7, and the pull ring 22 is pulled to unlock the lock tongue 13, and the lock tongue 13 moves out under the push of the second elastic member 24. Since the rubber ring 5 is elastic, the second contact surface 28 contacts the cover plate 1 during the movement of the lock tongue 13, pressing the cover plate 1 downward. If the force of the second elastic member 24 is not enough to push the cover plate 1 downward, the push plate 27 is pushed to assist the lock tongue 13 to move out, thereby fixing the cover plate 1.
