[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a quick-release valve cover, including a valve body 1 and a valve cover 2; the valve cover 2 covers the top of the valve body 1.

[0024] A connecting plate 3 is provided on the outer wall of the valve body 1, which serves as a transition structure for connecting the valve body 1 and the valve cover 2; a sealing ring 4 is provided on the top of the connecting plate 3, which can fill the gap between the valve body 1 and the valve cover 2, enhance the sealing performance, and prevent media leakage.

[0025] Several receiving parts 5 are respectively set on the connecting plate 3 and pass through the sealing ring 4 and the valve cover part 2 in sequence;

[0026] The driving component 6 is located at the middle of the upper end of the valve cover component 2;

[0027] Several inserts 7 are respectively set on the outer wall of the drive component 6 and the top of the valve cover component 2 and are slidably inserted into the receiving component 5; the drive component 6 is used to drive the inserts 7 into the receiving component 5 to complete the snap-fit ​​operation.

[0028] The fixing component 8 is set on the top of the valve cover component 2 and connected to the driving component 6; the fixing component 8 is used to fix the driving component 6, prevent the driving component 6 from rotating accidentally, and ensure the long-term stability of the snap-fit ​​structure.

[0029] Specifically, refer to Figure 3 The receiving element 5 includes a receiving block 51 and a receiving hole 52;

[0030] The receiving block 51 is installed on the connecting plate 3 and passes through the sealing ring 4 and the valve cover 2 in sequence, providing an insertion carrier for the insert 7, ensuring that the insert 7 can be inserted smoothly, and realizing the initial positioning and connection support between the valve cover 2 and the valve body 1.

[0031] The receiving hole 52 is opened on the outer wall of the receiving block 51, and its inner cavity top wall is designed in an inclined shape. When the insert 7 is inserted, the inclined structure can cooperate with the insert 7 and use the inclined surface to guide and squeeze. On the one hand, it guides the insert 7 to be inserted smoothly, and on the other hand, it generates a downward squeezing force on the valve cover 2 during the insertion process, so that the valve cover 2 fits the valve body 1 and the sealing ring 4 more tightly, thereby enhancing the sealing effect and connection stability.

[0032] Specifically, refer to Figure 2 The driving component 6 comprises a bearing ring 61, a rotating ring 62, and a ratchet 63;

[0033] The bearing ring 61 is located at the middle of the upper end of the valve cover 2. It serves as the mounting base for the rotating ring 62, provides rotational support for the rotating ring 62, ensures the stable rotation of the rotating ring 62, and provides a basic structure for power transmission for the action of the insert 7.

[0034] The rotating ring 62 is rotatably sleeved on the outer wall of the bearing ring 61. By rotating the rotating ring 62, the associated insert 7 is driven to move, so as to realize the action of insert 7 inserting into or disengaging from the receiving member 5. It is the key rotating component that drives the insert 7 to complete the snap-fit ​​operation.

[0035] The ratchet 63 is set on the outer wall of the rotating ring 62 and cooperates with the fixing member 8 to provide a structural basis for the rotation positioning of the rotating ring 62. The meshing relationship between the ratchet 63 and the fixing member 8 is used to prevent the rotating ring 62 from rotating accidentally and to ensure the stable position of the drive member 6 after the drive plug 7 is engaged.

[0036] Specifically, refer to Figure 3 The insert 7 includes a limit frame 71, an insert block 72, a hinge seat 73, and a connecting rod 74;

[0037] The limiting bracket 71 is installed on the top of the valve cover 2 and plays a limiting and guiding role in the sliding of the insert 72, ensuring that the insert 72 slides accurately in the predetermined direction and is smoothly inserted into the receiving hole 52, and avoiding the insertion 72 from shifting and affecting the snap-fit ​​effect.

[0038] The insert 72 can slide through the limiting frame 71 and be inserted into the receiving hole 52. Its cross-section is trapezoidal, which is adapted to the inclined inner cavity top wall of the receiving hole 52. When the rotating ring 62 rotates, the insert 72 is driven to slide through the hinge seat 73 and the connecting rod 74. The trapezoidal insert 72 cooperates with the inclined top wall of the receiving hole 52. During the insertion process, the inclined surface squeezes the insert 72 to gradually push the valve cover 2 downward, which enhances the fit between the valve cover 2 and the valve body 1 and the sealing ring 4, and improves the fixing effect and sealing performance. At the same time, the trapezoidal structure also makes the insert 72 more firmly locked in the receiving hole 52 and less likely to loosen.

[0039] The hinge seat 73 is respectively set at one end of the plug 72 and the outer wall of the swivel 62, providing a hinge mounting point for the connecting rod 74. Through the hinge method, the rotation of the swivel 62 is converted into the linear sliding of the plug 72, realizing the power transmission and motion form conversion.

[0040] The connecting rod 74 is hinged between the two hinge seats 73 and serves as a transmission component between the rotating ring 62 and the insert block 72. It stably transmits the rotational motion of the rotating ring 62 to the insert block 72, ensuring the continuity and stability of the insert 7's motion.

[0041] Specifically, refer to Figure 4 The fastener 8 consists of a fastener 81, a ratchet block 82, and a spring 83;

[0042] The fixing bracket 81 is set on the top of the valve cover 2, providing an installation and support structure for the ratchet block 82 and the spring 83, ensuring that the components of the fixing bracket 8 work stably and collaboratively, and realizing the function of fixing the rotating ring 62.

[0043] The ratchet block 82 can slide through the fixing frame 81 and engage with the ratchet teeth 63 on the outer wall of the rotating ring 62. When the rotating ring 62 rotates to the position where the insert 7 is engaged, the ratchet block 82 engages with the ratchet teeth 63 under the action of the spring 83, restricting the rotation of the rotating ring 62 and preventing the insert 7 from loosening due to accidental rotation of the drive component 6, thus ensuring the long-term stability of the engagement structure. When it is necessary to rotate the rotating ring 62, the ratchet block 82 can be manually pushed to disengage from the ratchet teeth 63, thereby releasing the restriction on the rotating ring 62.

[0044] Spring 83 is installed inside the fixing frame 81, with its two ends connected to the inner wall of the fixing frame 81 and the ratchet block 82, respectively. It provides a continuous elastic force to the ratchet block 82, causing the ratchet block 82 to always have a tendency to mesh with the ratchet tooth 63, thus ensuring the reliability and stability of fixing the fixing member 8 to the rotating ring 62.

[0045] Working principle

[0046] First, the valve cover 2 is placed on the valve body 1, so that the receiving part 5 on the connecting plate 3 passes through the sealing ring 4 and the valve cover 2 in sequence to complete the initial positioning; rotate the rotating ring 62 of the driving part 6, and the rotating ring 62 drives the insert block 72 of the insert 7 to slide along the limiting frame 71 through the hinge seat 73 and the connecting rod 74, and insert it into the receiving hole 52 of the receiving part 5; since the insert block 72 has a trapezoidal structure and the top wall of the receiving hole 52 is inclined, during the insertion process, the inclined surface makes the insert block 72 gradually jammed in, and at the same time, it generates a downward pushing force on the valve cover 2, which enhances the fit between the valve cover 2 and the valve body 1 and the sealing ring 4, and improves the sealing and connection stability;

[0047] When the insert 72 is fully inserted into the receiving hole 52, the rotating ring 62 rotates to the appropriate position. The ratchet 82 of the fixing part 8 engages with the ratchet 63 on the rotating ring 62 under the action of the spring 83, restricting the rotation of the rotating ring 62 and completing the snap-fit ​​fixing of the valve cover 2 and the valve body 1. At this time, the valve can be put into normal use. The medium is transmitted through the flow channel of the valve body 1. The valve cover 2 effectively seals the valve body 1, and the sealing ring 4 ensures the seal and prevents leakage.

[0048] If it is necessary to repair or replace parts inside the valve, such as the flow channel or sealing structure, the valve cover 2 needs to be removed. At this time, manually push the ratchet block 82 of the fixing part 8 to disengage it from the ratchet tooth 63 of the rotating ring 62, thereby releasing the rotation restriction on the rotating ring 62. Then rotate the rotating ring 62 in the opposite direction, and drive the insert 72 out of the receiving hole 52 through the connecting rod 74 and the hinge seat 73. The insert 7 separates from the receiving part 5, and the valve cover 2 can be removed upwards to perform maintenance operations inside the valve body 1. After the maintenance is completed, the valve cover 2 can be reinstalled and fixed by reversing the installation and snap-fit ​​process.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
