In this embodiment, container 1 includes a cup 11 and an end cap 12 attached to cup 11, where cup 11 and end cap 12 together form a chamber 10 for receiving an adhesive. In order to improve the sealing performance of the cavity 10, as shown in fig. 2, an annular convex ring 120 is disposed at the lower end of the end cap 12, an annular groove 110 coupled with the convex ring is disposed at the upper end of the cup body 11, the convex ring 120 can be inserted into the annular groove 110, a sealing ring 111 is disposed in the annular groove 110, and the convex ring 120 presses the sealing ring 111, so that a good sealing effect is achieved between the cup body 11 and the end cap 12, and air is prevented from entering the cavity 10. A channel for supplementing the adhesive is formed in the end cap 12, and a plug 121 is disposed on the channel for plugging the channel. The sealing between the plug 121 and the channel may be achieved by a tight fit, or may be achieved by a thread fit, which is not limited herein. When the adhesive needs to be supplemented, the plug 121 is removed, and the adhesive can be injected into the cavity 10 through the channel.

The container 1 comprises a plurality of side walls, and in fig. 2, for example, the container 1 is shown, and fig. 2 shows a first side wall 1a at the upper end, a second side wall 1b at the bottom, a third side wall 1c at the left side, and a fourth side wall 1d at the right side. Wherein the first sidewall 1a and the second sidewall 1b are oppositely disposed, and the third sidewall 1c and the fourth sidewall 1d are oppositely disposed. It should be noted that the side walls need not be flat, but may be curved, for example, when the container 1 is a rectangular parallelepiped, each side wall is plate-shaped, and when the container 1 is cylindrical, the third side wall 1c and the fourth side wall 1d are circular arc-shaped.

Among the plurality of side walls, at least one reference side wall and one opposite side wall disposed opposite to the reference side wall are included, for example, if the first side wall 1a is taken as the reference side wall, the second side wall 1b is taken as the opposite side wall; if the third side wall 1c is used as a reference side wall, the fourth side wall 1d is an opposite side wall.

The first matching part 13 is arranged on the reference side wall, the second matching part 20 matched with the first matching part is arranged on the top column 2, and the sliding matching is realized through the matching of the first matching part 13 and the second matching part 20. The first and second coupling portions 13 and 20 may be provided in the form of a shaft hole fitting, for example, in the present embodiment, as shown in fig. 2, the first coupling portion 13 is a guide shaft extending from the reference side wall toward the opposite side wall, and the second coupling portion 20 is a guide hole opened at the end of the top pillar 2, the guide shaft fitting into the guide hole; in another embodiment, as shown in fig. 3, the first coupling portion 13 is provided as a guide hole, and the second coupling portion 20 is provided as a guide shaft, and the same function can be achieved; in another embodiment, as shown in fig. 4, the top pillar 2 may extend to the outside of the reference sidewall, in which case the first coupling portion 13 is a guide hole penetrating the reference sidewall, the second coupling portion 20 is a guide shaft, and a sealing member 5 may be provided between the guide shaft and the guide hole to achieve sealing.

When the guide hole is the blind hole shown in fig. 2 and 3, in the moving process of the ejection column 2, the pressure in the guide hole will hinder the movement of the ejection column 2, the smaller the gap between the ejection column 2 and the guide hole is, the larger the resistance is, in order to make the movement of the ejection column 2 smoother, the side wall of the guide hole can be further provided with a drain hole 6 communicated with the cavity, in the moving process of the ejection column 2, the binder in the guide hole can flow through the drain hole 6, and therefore the movement of the ejection column 2 is smoother. By providing the drain hole 6, the clearance between the top pillar 2 and the guide hole can be further reduced, and the coaxiality can be improved.

As described above, the head post 2 can move toward the opposite side wall by being engaged with the first engaging portion 13, and the pipe passage 14 communicating with the outside is opened at a position corresponding to the head post 2 on the opposite side wall. Normally, the pipe passage 14 is abutted by the end of the top post 2 to isolate the chamber 10 from the outside. Specifically, an elastic member 3 is arranged between the top pillar 2 and the reference side wall, the elastic member 3 is in a compressed state, the top pillar 2 is driven to be tightly pressed against the opposite side wall through elastic force, and the pipe passage 14 is sealed.

In a preferred embodiment, the elastic member 3 is a spring, which is sleeved on the first mating portion 13, one end of which abuts against the reference sidewall, and the other end of which abuts against a shoulder 21 provided on the top pillar 2, and the top pillar 2 is driven by its own elasticity to seal the pipe passage 14.

In order to improve the sealing performance, as shown in fig. 5, the end of the tube passage 14 located in the cavity 10 is provided with a tapered hole 140, and correspondingly, the end of the top pillar 2 is provided with a tapered surface 22 adapted to the tapered hole 140, so that the tube passage 14 can be effectively sealed through the matching of the tapered hole 140 and the tapered surface 22, and the coaxiality of the top pillar 2 and the tube passage 14 during sealing is improved.

The tube passage 14 is adapted to the tube 4 to be coated with adhesive and may have an inner diameter slightly larger than the outer diameter of the tube 4 to facilitate insertion of the tube 4. When the pipe 4 is inserted into the pipe passage 14, it will push the top post 2 open (see fig. 6 and 7), and the end of the pipe 4 will enter the cavity 10 and contact the adhesive inside the cavity 10, so that the adhesive adheres to the outer surface of the pipe 4, completing the coating; when the pipe 4 is drawn out, the top pillar 2 will automatically reset under the action of the elastic element 3, automatically sealing the pipe passage 14 when the pipe 4 is drawn out.

In order to facilitate the insertion of the pipe 4 into the pipe passage 14 and ensure that the adhesive has a certain thickness, the diameter of the pipe passage 14 needs to be properly larger than that of the pipe 4, which results in that the pipe 4 may be deviated to one side in the pipe passage 14 when being inserted, so that the adhesive attached to the surface of the pipe 4 has uneven thickness. In order to solve the problem, an outward protruding positioning column 23 is further arranged at the end part of the top column 2 for blocking the pipe passage 14, and the positioning column 23 is arranged coaxially with the pipe passage 14 and can be inserted into the pipe 4, so that the end part of the pipe 4 is positioned at the central position of the pipe passage 14, and the adhesive is more uniformly coated on the outer part of the pipe 4.

As a preferred embodiment, as shown in fig. 5, the positioning column 23 is tapered as a whole, or its end is tapered, so as to facilitate guiding the pipe 4 to be sleeved on the positioning column 23; in addition, in order to facilitate the insertion of the pipe 4 into the pipe passage 14, the end of the pipe passage 14 for inserting the pipe 4 is provided with a flare 141 that becomes gradually smaller from the outside to the inside.

The positioning post 23 has another important function that: which can effectively prevent the adhesive from entering the inside of the pipe 4. Specifically, when the top pillar 2 is not pressed by the pipe 4, the positioning pillar 23 is located inside the pipe passage 14 and isolated from the cavity 10, and therefore is not contaminated by the adhesive, and when the pipe 4 is inserted into the pipe passage 14, the pipe 4 will be sleeved on the positioning pillar 23 and the end opening thereof is sealed by the positioning pillar 23 or the rest of the top pillar 2, so that even if the end of the pipe 4 is immersed in the adhesive, the inside of the pipe 4 is isolated from the adhesive, and the adhesive cannot enter the inside of the pipe 4.

It will be appreciated that, with reference to fig. 6 and 7, the length of the end of the pipe 4 to which the adhesive can be applied is the same as the length of the end to which the adhesive can be immersed, and is also determined by the maximum distance L by which the top pillar 2 can be retracted, and therefore, the length of the adhesive applied to the end of the pipe 4 can be controlled by controlling the maximum distance L by which the top pillar 2 can be moved. During the use, the staff only need with pipe fitting 4 promote to fore-set 2 and benchmark lateral wall contact, can guarantee that the binder length of coating meets the requirements on pipe fitting 4 at every turn, and the coating all has fine uniformity at every turn.

It should be pointed out that the binder of this application adheres to frock is not restricted to once can only coat for a pipe fitting 4, as shown in fig. 8, can set up a plurality of pipe fitting passageways 14 on the relative lateral wall to correspond and set up supporting fore-set 2 and elastic component 3 etc. can make the binder of this application adhere to frock and coat for many pipe fittings 4, improve coating efficiency greatly.
