[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0028] Embodiment 1

[0029] Referring to Figs. 1-3 , the present embodiment provides an inner expanding type grabbing structure.

[0030] The limiting mechanism 100 is used for limiting the aerosol valve, providing grabbing force, and the grabbing ring 101 can be opened in a certain interval. The inner wall of the aerosol valve is provided with a 0.1-0.3mm notch for accommodating the grabbing ring 101.

[0031] The opening and closing mechanism 200 is used for controlling the pushing of the grabbing ring 101 to open. The grabbing ring 101 itself is provided with a movable elastic structure, and a pushing rod 201 is slidably arranged on the inner wall of the grabbing ring 101. A slope 202 is fixedly arranged at the contact position of the inner wall of the grabbing ring 101 and the pushing rod 201. The pushing rod 201 directly contacts the slope 202 to push the grabbing ring 101 to open. The tail of the pushing rod 201 and the internal structure of the grabbing ring 101 are arranged to only perform constant vertical movement, so that when the top of the pushing rod 201 pushes the slope 202, the grabbing ring 101 is stretched.

[0032] The end of the push rod 201 can be connected to any power source for pushing, such as a gas cylinder, a motor, etc. Corresponding to the inner wall of the aerosol valve of the grabbing ring 101, a slot of 0.1-0.3 mm is fixed. Once the grabbing ring 101 is fully extended, it can be clamped into the slot to firmly contact the aerosol valve. Under the drive of the subsequent power source, the aerosol valve can be directly lifted by the cooperation of the grabbing ring 101 and the slot, which is convenient for conveying gas into the aerosol can body.

[0033] The device can adjust the movement stroke of the push rod 201 to directly control the opening range of the grabbing ring 101, so as to control the fitting size of the grabbing ring 101, and be compatible with aerosol valves of different sizes, and the adaptability is also greatly improved.

[0034] Embodiment 2

[0035] Referring to Figs. 1-4 , this embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0036] The opening and closing mechanism 200 further comprises a power assembly 203 for connecting to the overall device, and remotely providing power. The push rod 201 is further drivenly connected to the bottom of the power assembly 203. The power assembly 203 can be a gas cylinder, which can exert a vertical downward thrust on the push rod 201.

[0037] The bottom of the push rod 201 is further connected to a matching shaft 201a. The connection between the matching shaft 201a and the push rod 201 is detachable thread, or other connection modes, which are not limited. When the power assembly 203 starts to work, the matching shaft 201a can be driven to move linearly by pushing the push rod 201. The matching shaft 201a is located in the inner wall of the grabbing ring 101, and directly contacts the slope 202 of the inner wall of the grabbing ring 101 instead of the push rod 201. The outer wall structure of the matching shaft 201a is smoother and more stable than the connecting section of the end of the push rod 201, and is not easy to wear and damage the inner wall of the grabbing ring 101.

[0038] The matching shaft 201a linearly contacts the slope 202, and pushes the grabbing ring 101 to expand through cooperation with the slope 202. The bottom of the grabbing ring 101 is fixedly provided with an extension opening 101a which slightly protrudes from the outer wall of the grabbing ring 101. The extension opening 101a and the outer wall of the grabbing ring 101 form a hook groove 101b, and the inclination angle of the hook groove 101b is designed to better and firmly contact the aerosol valve, thereby improving the grabbing efficiency.

[0039] The sealing sleeve 102b is located outside the wall of the whole set of grabbing ring 101 structure, and a guide ring 102 is fixedly arranged between the sealing sleeve 102b and the grabbing ring 101. The guide ring 102 can contact the aerosol can body and has a good guiding effect, so that the grabbing ring 101 can be accurately located above the aerosol valve for subsequent operation. The bottom of the guide ring 102 is also fixedly provided with a sealing ring 102a. The sealing ring 102a can be in the form of a sealing O-ring and the like. The main function is to ensure the air tightness of the sealing sleeve 102b. When the conveying gas passes through the valve lifted by the grabbing ring and enters the aerosol can body, no gas leakage will occur.

[0040] Embodiment 3

[0041] With reference to Figs. 1-5 , the embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0042] The support mechanism 300 is used to maintain the stable operation of the whole set of device. A telescopic rod 301 is further fixedly arranged at the top of the sealing sleeve 102b. The telescopic rod 301 can drive the whole shell of the sealing sleeve 102b to move vertically to a certain extent under the output of the external power source, and perform the movement process of “descending to tightly contact the can body” and “rising to loosen the can body”.

[0043] A stable platform 302 is arranged at the top of the telescopic rod 301. A driving assembly 302a is fixedly installed on the stable platform 302 and penetrates through the stable platform 302 and is connected with the telescopic rod 301. The driving assembly 302a can be a pneumatic cylinder and can output an action on the telescopic rod 301 to drive the sealing sleeve 102b to move.

[0044] A lifting fine adjustment part 302a-1 is arranged at the top of the driving assembly 302a. The lifting fine adjustment part 302a-1 itself is located on the upper structure outer wall of the telescopic rod 301 and belongs to a valve lifting fine adjustment nut. The lifting fine adjustment part 302a-1 can debug and maintain the stroke of the device before the whole set of device works.

[0045] A power assembly 203 is arranged at the top of the lifting fine adjustment part 302a-1. An adjusting module 303 is further installed above the power assembly 203. The stroke and height can also be adjusted by screw nut rotation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be covered in the scope of the claims of the present application.
