UTILITY MODEL CONTENTS

[0003] Therefore, it is necessary to provide a locking device and bubble water machine in view of the problem that the water bottle and the gas injection nozzle of many bubble water machines on the market are connected by screwing, which is more troublesome and time-consuming to operate.

[0004] A locking device comprises: a housing assembly; a drive seat, the drive seat is rotatably connected with the housing assembly through a rotating shaft, the axis of the rotating shaft extends along the horizontal direction, the drive seat is provided with a first through hole for passing through a water bottle or a gas injection nozzle along the height direction; a locking assembly, the locking assembly is movably arranged on the drive seat, the drive seat is configured to rotate to drive the locking assembly to move along the radial direction of the first through hole and at least have a locking position and a release position, when the locking assembly is in the locking position, the locking assembly is configured to be able to limit the movement of the water bottle, when the locking assembly is in the release position, the locking assembly is away from and releases the water bottle.

[0005] The locking device provided by the application comprises a driving seat rotatably arranged on a shell assembly and a locking assembly movably arranged on the driving seat, so that the locking assembly is activated when the driving seat is rotated by a user, and when the user needs to make bubble water, the user only needs to rotate the driving seat to drive the locking assembly to the release position, so that the water bottle can be easily inserted into the driving seat along the axis of the first through hole and further connected with the gas injection nozzle, and then the water bottle and the driving seat are simultaneously swung to reset, so that the locking assembly is activated to the locking position, and thus the locking assembly can automatically lock the water bottle, and the water bottle can be securely arranged and the gas injection operation can be safely carried out. When the gas injection is completed, the user swings the water bottle and the driving seat again to activate the locking assembly to the release position, so that the water bottle can be easily pulled out. By using the locking device of the application, the user can easily complete the assembly and disassembly of the water bottle by using the simple swinging action of the driving seat and the locking assembly, and the operation is convenient and fast, so that the user experience can be greatly improved.

[0006] In one of the embodiments, the locking assembly comprises a locking block and a spring, the driving seat is formed with a first protrusion in the height direction, the locking block is movably arranged on the driving seat, one end of the locking block is in sliding abutment with the shell assembly, and the other end of the locking block is connected with the first protrusion through the spring. When the locking assembly moves from the release position to the locking position, the locking block moves along the radial direction of the first through hole and approaches the first through hole, and the spring is deformed and accumulates elastic restoring force. By using the above structure, when the user rotates the driving seat to switch the locking assembly between the release position and the locking position, the one end of the locking block away from the first through hole slides relative to the shell assembly, so that the distance between the locking block and the first through hole is changed by driving the locking block to abut against different positions of the shell assembly. When the driving seat is rotated to drive the locking assembly to move from the release position to the locking position, the shell assembly extrudes the locking block to make the locking block approach the first through hole and restrictively interfere with the water bottle. When the driving seat is rotated to drive the locking assembly to move from the locking position to the release position, the locking block moves away from the first through hole under the avoidance of the shell assembly and the elastic force of the spring, so that the mounting position of the locking block away from the water bottle can allow the water bottle to be inserted or removed.

[0007] In one of the embodiments, the shell assembly is formed with an abutting piece, the lock block is in sliding abutment with the abutting piece away from one end of the first through hole, the abutting piece comprises a first abutting part and a second abutting part, the distance between the first abutting part and the axis of the first through hole is smaller than the distance between the second abutting part and the axis of the first through hole, when the locking assembly is in the locked position, the lock block is in abutment with the first abutting part, when the locking assembly is in the released position, the lock block is in abutment or opposite to the second abutting part. By adopting the above structure, the distance between the lock block and the first through hole can be changed by rotating the driving seat to drive the lock block to slide and abut against different positions of the abutting piece.

When the first abutting part abuts against the lock block, the lock block is pressed to approach the first through hole to restrict the water bottle. When the locking assembly moves from the locked position to the released position, the lock block abuts against or is opposite to the second abutting part. Since the distance between the second abutting part and the axis of the first through hole is larger, the lock block will move away from the first through hole under the elastic force of the spring, thereby allowing the water bottle to be inserted into or separated from the locking device.

[0051] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood and to be implemented, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein, and the scope of the present application is not limited to the specific embodiments disclosed below.

[0053] The lock device according to some embodiments of the present application will be described below with reference to the accompanying drawings.

[0054] As Figures 1 to 9As shown, the embodiment discloses a locking device, comprising: a housing assembly 1; a driving seat 2, the driving seat 2 is rotatably connected with the housing assembly 1 through a rotating shaft 4, the axis of the rotating shaft 4 extends along the horizontal direction, the driving seat 2 is provided with a first through hole 201 along the height direction for passing through a water bottle or a gas injection nozzle; a locking assembly 3, the locking assembly 3 is movably arranged on the driving seat 2, the driving seat 2 is configured to rotate to drive the locking assembly 3 to move along the radial direction of the first through hole 201 and at least has a locking position and a release position, when the locking assembly 3 is in the locking position, the locking assembly 3 is configured to be able to limit the movement of the water bottle, when the locking assembly 3 is in the release position, the locking assembly 3 is away from and releases the water bottle.

[0055] The application provides a locking device, the driving seat 2 is rotatably arranged on the housing assembly 1, and the locking assembly 3 is movably arranged on the driving seat 2, so that when the user operates the driving seat 2 to rotate, the locking assembly 3 is also driven to move, when the user needs to make bubble water, only needs to rotate the driving seat 2 to drive the locking assembly 3 to move to the release position, and then the water bottle can be easily inserted into the driving seat 2 along the axis direction of the first through hole 201 and further connected with the gas injection nozzle in alignment, then the water bottle and the driving seat 2 are simultaneously swung to reset, so that the locking assembly 3 moves to the locking position, thereby the locking assembly 3 can automatically complete the locking of the water bottle, and the water bottle can be securely arranged and the gas injection operation can be safely carried out, when the gas injection is completed, the user swings the water bottle and the driving seat 2 again to make the locking assembly 3 move to the release position, so that the water bottle can be easily pulled out. By using the locking device of the application, the driving seat 2 and the locking assembly 3 are matched, the user can easily complete the assembly and disassembly of the water bottle by using a simple swinging action, the operation is convenient and fast, and thus the use experience of the user can be greatly improved.

[0056] As Figures 5 to 9As shown, in addition to the features of the above embodiments, this embodiment further defines that: the locking component 3 includes a locking block 31 and a spring 32, the drive seat 2 has a first protrusion 221 formed along the height direction, the locking block 31 is movably disposed on the drive seat 2, one end of the locking block 31 slides against the housing component 1, and the other end of the locking block 31 is connected to the first protrusion 221 through the spring 32. When the locking component 3 moves from the release position to the locking position, the locking block 31 moves along the radial direction of the first through hole 201 and approaches the first through hole 201, and the spring 32 deforms and accumulates elastic restoring force. By adopting the above structure, when the user rotates the drive seat 2 to switch the locking component 3 between the release position and the locking position, the end of the locking block 31 away from the first through hole 201 will slide relative to the housing component 1. This causes the locking block 31 to abut against the housing component 1 at different positions, thus changing the distance between the locking block 31 and the first through hole 201. When the drive seat 2 rotates to move the locking component 3 from the release position to the locking position, the housing component 1 presses the locking block 31 so that the locking block 31 is close to the first through hole 201, which can restrict interference with the water bottle. When the drive seat 2 rotates to move the locking component 3 from the locking position to the release position, the locking block 31 moves away from the first through hole 201 under the avoidance of the housing component 1 and the elastic force of the spring 32. Thus, the locking block 31 is moved away from the installation position of the water bottle, allowing the water bottle to be inserted or removed.

[0057] like Figures 6 to 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is formed with an abutment 13, and the end of the locking block 31 away from the first through hole 201 slides against the abutment 13. The abutment 13 includes a first abutment portion 131 and a second abutment portion 132. The distance between the first abutment portion 131 and the central axis of the first through hole 201 is less than the distance between the second abutment portion 132 and the central axis of the first through hole 201. When the locking assembly 3 is in the locked position, the locking block 31 abuts against the first abutment portion 131. When the locking assembly 3 is in the released position, the locking block 31 abuts against or is opposite to the second abutment portion 132. By adopting the above structure, the drive seat 2 rotates to drive the locking block 31 to slide and abut against the abutment member 13 at different positions, which can change the distance between the locking block 31 and the first through hole 201. Specifically, the abutment member 13 is provided with a first abutment part 131 and a second abutment part 132 at different distances from the central axis of the first through hole 201. When the first abutment part 131 abuts against the locking block 31, it will squeeze the locking block 31, causing the locking block 31 to approach the first through hole 201 and restrict interference with the water bottle. When the locking assembly 3 moves from the locked position to the released position, the locking block 31 abuts against or is opposite to the second abutment part 132. Since the distance between the second abutment part 132 and the central axis of the first through hole 201 is greater, the locking block 31 will move away from the first through hole 201 under the elastic force of the spring 32, thereby allowing the water bottle to be inserted into or removed from the locking device.

[0058] As shown in Figures 6 to 9 In addition to the features of the above embodiments, the present embodiment is further defined as: the second abutting portion 132 is a groove 104, when the locking assembly 3 is in the locked position, the locking block 31 is located outside the groove 104, and when the locking assembly 3 is in the released position, the locking assembly 3 is clamped in the groove 104. By adopting the above structure, when the clamping block slides from the first abutting portion 131 to the second abutting portion 132, it will extend into the groove 104 under the elastic force of the spring 32, so that the groove 104 can limit the locking block 31, so that the locking assembly 3 can be kept in the released position.

[0061] As shown in Figure 6 and Figure 7 In addition to the features of the above embodiments, the present embodiment is further defined as: one side of the abutting piece 13 is formed with a resilient abutting rib 133, and when the locking assembly 3 is in the released position, the peripheral wall of the driving seat 2 abuts against the resilient abutting rib 133. By providing the resilient abutting rib 133, the driving seat 2 can be limited to avoid excessive rotation of the driving seat 2, and in addition, the resilient abutting rib 133 can also buffer the impact force of the driving seat 2 to a certain extent, which is beneficial to reduce the sound.

By forming the first sliding groove 301 on the locking block 31, the movement direction of the locking block 31 can be limited by the cooperation of the first protrusion 221 and the first sliding groove 301, so as to avoid position deviation of the locking block 31.

[0063] As shown in Figure 3 and Figure 4As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the driving seat 2 is formed with a second protrusion 222 in the height direction, and the top end of the second protrusion 222 is bent and abuts against the top wall of the locking block 31. Through the arrangement of the second protrusion 222, the locking block 31 can be limited by the abutting of the bent part of the second protrusion 222 and the top wall of the locking block 31, so as to avoid the displacement or accidental loosening of the locking block 31 in the height direction during the movement, and make the working of the locking assembly 3 more stable and reliable.
