In the drawings: 1. a body; 2. a sleeve; 3. a transmission mechanism; 4. a push rod; 5. a waterproof assembly; 6. locking a ring; 7. a waterproof cap; 8. a limiting structure; 9. an external thread; 10. and (4) a thread structure.

Detailed Description

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-4, the utility model discloses a novel waterproof structure of a microneedle device, which comprises a body 1 and a sleeve 2 sleeved on the body 1, wherein the body 1 is internally provided with a transmission mechanism 3, the sleeve 2 is provided with a push rod 4, and the transmission mechanism 3 drives the push rod 4 to move in a telescopic manner; a waterproof assembly 5 is fixed in the sleeve 2, and the waterproof assembly 5 comprises a waterproof cap 7 and a locking ring 6 which is matched with the waterproof cap 7 to be tightly assembled.

Specifically, the transmission mechanism 3 comprises a motor and a transmission rod in transmission connection with the motor, so as to drive the push rod 4 to vertically extend and retract; the waterproof assembly 5 is positioned between the push rod 4 and the transmission rod of the transmission mechanism 3, so that essence can be effectively prevented from flowing back to the transmission mechanism 3 of the body 1 from the sleeve 2; the waterproof cap 7 can be made of a silica gel material or an elastic material; because the waterproof assembly 5 is arranged between the transmission mechanism 3 and the push rod 4, and a certain gap is formed between the transmission mechanism 3 and the push rod 4, when the transmission rod of the transmission mechanism 3 pushes the push rod 4, the push rod 4 can push the waterproof cap 7, so that the waterproof cap 7 is made of silica gel or elastic material, and then the locking ring 6 is matched with the waterproof cap 7 for use, so that the waterproof cap 7 is prevented from falling off during telescopic movement, and is firmer; the locking ring 6 is a hollow locking ring 6, and the inner side of the locking ring 6 is polygonal, so that the locking assembly of a polygonal screwdriver is convenient, and the assembly is quick and convenient.

During assembly, the waterproof cap 7 is sleeved in the locking ring 6 and then placed in the sleeve 2, then the locking ring 6 is in threaded assembly with the sleeve 2, the waterproof cap 7 is tightly assembled with the limiting structure 8, then the push rod 4 is assembled in the sleeve 2, and finally the sleeve 2 is in threaded assembly with the body 1.
