A buckle anti-loss follow-up pump

Abstract

A buckle anti-loss follow-up press pump includes a press head, a screw thread, a main column and a buckle. The press head includes a liquid inlet pipe, a sleeve surrounding the liquid inlet pipe and a liquid outlet channel connected to the liquid inlet channel. A guide cylinder is provided on the top plate of the screw thread. The main column passes through the guide cylinder and is connected to the liquid inlet channel of the press head. The guide cylinder extends into a cavity formed by the liquid inlet channel and the sleeve. The buckle cooperates with the sleeve and the top plate of the screw thread. It is characterized in that the buckle cooperates and locks with the top plate of the screw thread and the lower end support of the sleeve. After unlocking, the buckle moves with the press head. Due to the use of such a structure, it is convenient to convert from the locked state to the unlocked state and from the unlocked state to the locked state. In the unlocked state, the buckle moves with the press head, and the buckle does not need to be stored separately.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 3 , Figure 4 As shown, a buckle anti-loss follow-up press pump comprises a press head 1, a screw thread 2, a main column 3 and a buckle 4. The press head 1 comprises a liquid inlet pipe 11, a sleeve 12 surrounding the liquid inlet pipe and a liquid outlet channel 13 connected with the liquid inlet channel. A guide cylinder 21 is provided on the top plate of the screw thread 2. The main column 3 passes through the guide cylinder 21 and is connected with the liquid inlet channel 11 of the press head 1. The guide cylinder 21 extends into a cavity formed by the liquid inlet channel 11 and the sleeve 12. The buckle 4 cooperates with the sleeve 12 and the top plate of the screw thread 2.

[0024] The buckle 4 is matched and locked with the top plate of the screw thread 2 and the lower end support of the sleeve 12; after unlocking, the buckle 4 moves with the push head 1.

[0025] like Figure 7 , Figure 8 As shown, the buckle 4 includes a supporting cylinder portion 41, an upper inclined portion 42 and a lower inclined portion 43 provided on the supporting cylinder portion; the upper inclined portion 42 is located in the second quadrant, and the lower inclined portion 43 is located in the fourth quadrant;

[0026] It can also be: Fig. 9 As shown, the upper slope portion 42 is located in the first quadrant, and the lower slope portion 43 is located in the third quadrant.

[0027] like Figure 3 As shown, in the locked state, the guide cylinder 21 passes through the supporting cylinder body 41, the upper inclined surface 42 is supported and matched with the lower end of the sleeve 12, and the lower inclined surface 43 is supported and matched with the top plate of the screw thread 2;

[0028] like Figure 6 As shown, in the unlocked state, the supporting cylinder portion 41 is sleeved on the sleeve 12 and moves with the push head 1.

[0029] The inner diameter D1 of the support cylinder portion 41 is smaller than the outer diameter D2 of the sleeve 12, and the support cylinder portion 41 and the sleeve 12 can be detachably matched. Alternatively, the support cylinder portion 41 and the sleeve 12 can be interference-fitted.

[0030] As a further improvement of the present invention: a fulcrum 44 is provided adjacent to the lower slope surface of the support cylinder 41. Fig.10 As shown, the fulcrum 44 includes a bottom plane portion 441 and arc-shaped portions 442 located at both ends, one arc-shaped portion 442 is connected to the lower end of the supporting cylinder portion 41 , and the other arc-shaped portion 442 is connected to the lower inclined portion 43 .

[0031] Figure 3 It is a cross-sectional view of the locked state of the present invention. Figure 3 In this state, first, the buckle 4 rotates counterclockwise, and the buckle rotates in a direction perpendicular to the main column; the fulcrum 44 slides on the top plate of the screw thread 2; secondly, the fulcrum 44 cooperates with the top plate support of the screw thread 2; thirdly, the lower pressing head 1 and the sleeve 12 of the pressing head are inserted into the supporting cylinder part 41, or the buckle 4 moves upward, and the supporting cylinder part 41 is sleeved on the sleeve 12; it moves up and down with the pressing head 1.

[0032] When it is necessary to lock again, the supporting cylinder portion 41 and the sleeve 12 are disassembled, and the buckle 4 is rotated clockwise.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, which are also considered as the protection scope of the present invention.
