Example (b):

as shown in fig. 1-4, the present invention provides a fluid pushing device, which comprises a driving part 1 and a rubber storage tube 2. One end of the driving part 1 is provided with a connecting buckle 3. The rubber storage tube 2 is provided with a connector in cooperation with the connecting buckle 3 so that the connector can be detachably connected to the connecting buckle 3. Specifically, the connector comprises a plurality of connecting pieces 4. The connecting pieces 4 are evenly distributed along the circumferential direction of the rubber storage tube 2, and the plane where the connecting pieces 4 are located is vertical to the axis of the rubber storage tube 2. A clamping gap for clamping the connecting sheet 4 is arranged between the connecting buckle 3 and the end surface of the driving part 1. After the connecting piece 4 is clamped in the clamping gap, the rubber storage tube 2 is firmly connected to the driving part 1. The driving part 1 is provided with a connecting buckle 3 in cooperation with each connecting piece 4. The connecting buckles 3 are uniformly distributed in a ring shape. And each connecting sheet 4 is clamped in a clamping gap, so that the connecting stability of the rubber storage tube 2 is ensured. Because the rubber storage tube 2 is smaller, the connecting sheet 4 and the connecting buckle 3 are symmetrically arranged, so that the rubber storage tube 2 is stably connected with the driving part 1, and the stress at the joint of the rubber storage tube 2 is ensured to be uniform. The driving part 1 is provided with a pushing part in cooperation with the rubber storage tube 2, so that the pushing part is accommodated in the rubber storage tube 2 when the rubber storage tube 2 is connected to the driving part 1. The driving part 1 is also provided with a driving part in cooperation with the pushing part, so that the driving part drives the pushing part to push the glue solution in the glue storage tube 2. Specifically, the driving unit 1 is provided therein with a battery 12, a circuit board 13, a driving motor 9, and the like. The drive section 1 is also provided with control buttons and the like. The rotation of the driving motor 9 can be controlled by the control button, and the pushing part is further controlled to push out the glue solution.

The utility model discloses a fluid pushes away when crowding the device and uses, with the 3 butt joints of connector and connector link, and then will be equipped with the glue solution store up rubber tube 2 and connect in drive division 1. Specifically, the connecting piece 4 is placed on one side of the clamping gap and the rubber storage tube 2 is rotated, so that the connecting piece 4 is rotated to the clamping gap, and the rubber storage tube 2 filled with the rubber solution is connected to the driving part 1. And then the pushing part can be controlled to push the glue solution in the glue storage tube 2 by controlling the action of the driving part 1, so that glue injection is performed. The electric mode is adopted to control the pushing part, so that the pushing part is controlled more accurately, the accuracy of glue injection quantity is better guaranteed, and the glue injection quality is improved. In addition, the rubber storage tube 2 and the driving part 1 are detachably connected, so that the rubber storage tube 2 is convenient to replace. After the glue solution in the glue storage tube 2 is used up, the glue solution can be continuously supplied by replacing the glue storage tube 2, and the use is convenient. Finally, the fluid pushing device does not need to be matched with devices such as an air pump and the like for use, so that the volume is reduced, the carrying is convenient, and the use is more convenient.

In this embodiment, a limiting strip 5 is disposed between the connecting buckle 3 and the end surface of the driving portion 1. Along the circumference of the circle where the connecting buckles 3 are located, the limiting strips 5 are located on the same side of the connecting buckles 3. After the rubber storage tube 2 rotates and enables the connecting piece 4 to abut against the limiting strip 5, the limiting strip 5 blocks the connecting piece 4, and therefore the connecting piece 4 is prevented from sliding out of the other side of the clamping gap due to over rotation of the rubber storage tube 2.

In this embodiment, the pushing portion includes a push rod 6 and a piston 7. The push rod 6 is connected with the driving piece in a transmission way. The piston 7 is connected to one end of the push rod 6. The glue solution in the glue storage tube 2 can be completely pushed out by adopting the mode that the piston 7 is matched with the glue storage tube 2, so that the residual glue solution in the glue storage tube 2 is avoided.

In this embodiment, the end of the push rod 6 is provided with a connecting ball 8. The outer diameter of the connecting ball 8 is larger than that of the push rod 6. The piston 7 is provided with an elastic containing groove in cooperation with the connecting ball 8, so that after the connecting ball 8 is embedded into the containing groove, the inside of the containing groove is attached to the outer wall of the connecting ball 8. The piston 7 is generally made of silicone, which has a good elasticity in itself. And then make connecting ball 8 can pass in and out the storage tank under the condition of exerting certain external force, and then make piston 7 can change as required. Thereby enabling the piston 7 to be conveniently replaced after being damaged.

Further, the driving member includes a driving motor 9 and a rotating nut 10. The swivel nut 10 is rotatably coupled to an inner wall of the driving part 1. The outer wall of the swivel nut 10 is provided with external teeth so that the swivel nut 10 is in transmission connection with the drive motor 9 through the external teeth. The push rod 6 is a screw rod. The screw is threadedly coupled to the swivel nut 10. The cooperation mode of nut and screw rod makes the flexible control of volume of push rod 6 more accurate. Meanwhile, the driving motor 9 drives the nut to rotate, so that the push rod 6 stretches. In the process of extension and retraction of the push rod 6, the push rod 6 cannot rotate, so that friction cannot be generated between the push rod 6 and the piston 7, and the piston 7 is prevented from being damaged quickly.

In this embodiment, the push rod 6 is provided in a flat shape. The drive part 1 is provided with a guide ring 11 through which the push rod 6 passes. The shape of the guide hole of the guide ring 11 is the same as the shape of the cross section of the push rod 6 so that the outer wall of the push rod 6 is fitted to the inner wall of the guide ring 11. The guide ring 11 guides the push rod 6, so that the piston 7 moves more stably, and the glue injection quality is guaranteed. In addition, the cooperation of the flat push rod 6 and the guide ring 11 can effectively prevent the rotation of the rotary nut 10 from driving the push rod 6 to rotate, thereby ensuring the stability.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
