[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] Example

[0025] This embodiment provides a detachable liquid tube, which includes an inner tube 1, an outer tube 2 and a liquid cup 3. Figure 1 As shown. The two ends of the inner tube 1 in the longitudinal direction are respectively an insertion end and a connection end, and the insertion end is a closed structure. The two ends of the outer tube 2 in the longitudinal direction are respectively a first end and a second end, and the second end is a closed structure. The insertion end of the inner tube 1 is preferably designed to be closed with a plug 12, that is, the inner tube 1 is composed of an inner tube body 11 and a plug 12. The inner tube body 11 is a tube structure, and the plug 12 is used to plug one end opening of the inner tube body 11 to form a closed end, to ensure that the coating liquid added to the inner tube 1 does not leak from the insertion end, and can also ensure that the coating liquid in the inner tube 1 does not flow out from the connection end during the movement of the liquid pipe. The plug 12 can be made of a soft material such as rubber or silicone, and plugs the insertion end opening of the inner tube body 11 like a plug. Of course, it should be noted that the plug 12 is not limited to this, and can also be other sealing structures such as a sealing cover. At the same time, the sealing method is not limited to plugging, and can also be threaded or sleeved. The second end of the outer tube 2 is preferably sealed with a block 22. Specifically, the outer tube 2 is composed of an outer tube body 21 and a block 22. The outer tube body 21 is preferably a bellows, which not only guides the inner tube 1 but also shields it from light, preventing the coating liquid within the inner tube 1 from evaporating due to external light. The block 22 is preferably threaded to achieve a hermetic connection with the outer tube 2, but this sealing method is not limited to this. Alternatively, a plug or a sealing cap may be used.

[0026] The liquid cup 3 is connected to the connecting end. The liquid cup 3 is a cup-shaped structure with an opening at the upper end and a through hole formed at the bottom. The connecting end is connected to the bottom end of the liquid cup 3 so that the inner cavity of the liquid cup 3 is connected to the inner cavity of the inner tube 1 through the through hole. The specific connection method between the liquid cup 3 and the connecting end can be in various forms. In this embodiment, it is preferred to set a pipe joint structure at the bottom end of the liquid cup 3, and the connecting end is directly sleeved on the pipe joint structure. Of course, other connection methods are also possible, such as threaded connection, etc.

[0027] During specific implementation, the inner tube 1 is arranged in the outer tube 2, and the inner tube body 11 is provided with one end of the plug 12, that is, the insertion end of the inner tube 1 is inserted into the outer tube 2 through the first end, and the liquid cup 3 is located outside the outer tube 2. The outer diameter of the inner tube body 11 and the maximum outer diameter of the plug 12 are both smaller than the inner diameter of the outer tube 2, so that the insertion end of the inner tube 1 can be more easily inserted into the outer tube 2. The liquid cup 3 is directly placed at the opening of the outer tube 2 without threaded connection, and the liquid cup 3 is placed outside the outer tube 2, which makes it easier for the operator to pull out the inner tube 1 from the outer tube 2 for cleaning. Figure 2 As shown. The inner tube 1 is in communication with the outside air through the opening of the liquid cup 3, and can be used to add coating liquid to the inner tube 1. The product to be coated can pass through the liquid cup 3 into the coating liquid in the inner tube 1 to achieve dip coating. The length of the inner tube body 11 can be designed according to the coating length required by the product, and the length of the outer tube body 21 is generally designed according to the maximum coating length required by the product, and the length of the inner tube body 11 is greater than or equal to zero and less than or close to the length of the outer tube 2. For products with a shorter coating length, the length of the inner tube 1 can be shortened according to the coating length requirements.

[0028] This embodiment also provides a detachable liquid pipe assembly, which is composed of a mounting seat 4, a liquid pipe turning seat and a plurality of the above-mentioned detachable liquid pipes. Figure 2As shown. The mounting base 4 can be composed of two parallel, spaced-apart plate-like structures, including an upper plate 41 and a lower plate 42. The lower plate 42 is provided with a plurality of through-holes. The first end of the outer tube 2 is then fixedly connected to the lower plate 42, so that the inner cavity of the outer tube body 21 communicates with the corresponding through-holes. There are various ways to secure the first end to the lower plate 42, such as bolting. Specifically, threaded holes can be provided on the side of the lower plate 42 at locations corresponding to the through-holes. The first end of the outer tube 2 is inserted into the through-holes, and the bolts are then tightened to secure the outer tube 2 within the through-holes. Of course, the outer tube 2 can also be secured using other methods, such as snap-on mounting, welding, gluing, etc. The upper plate 41 is provided with a plurality of mounting holes, which correspond one-to-one with the through-holes on the lower plate 42. When the inner tube 1 is placed within the outer tube 2, the larger size of the liquid cup 3 allows the liquid cup 3 to be placed outside the outer tube 2 and fit neatly within the mounting holes. The liquid cup 3 and the mounting base 4 are designed to be detachable. Preferably, a threaded hole is provided on the side of the upper plate 41 at a position corresponding to the mounting hole, and a detachable connection is achieved by screwing a bolt, that is, when installing the inner tube 1, it is only necessary to tighten the bolt to tighten the liquid cup 3, and when removing the inner tube 1, it is only necessary to loosen the bolt, and the inner tube 1 can be conveniently pulled out of the outer tube 2. In order to ensure that the bolt does not cause damage to the liquid cup 3 when tightening the liquid cup 3, a gasket structure can be provided at the end of the bolt. Figure 3 As shown in the figure, a spring structure 411 is adaptively provided at the position of the threaded hole corresponding to the mounting hole. When the bolt is tightened, the bolt pushes the spring structure 411 so that it fits tightly with the side wall of the liquid cup 3, thereby clamping the liquid cup 3 in the mounting hole.

[0029] The liquid pipe steering seat includes a rotatable steering roller 5, and the outer tube 2 passes through the bottom of the steering roller 5 and wraps around the two sides of the steering roller 5. This can make the liquid pipe smoother and more stable when moving up or down, and on the other hand, it can also make the liquid pipe adopt a vertically movable layout at both ends in the coating equipment, such as Figure 2 As shown, this saves equipment space, makes the equipment more compact, and facilitates miniaturization. In practice, by driving the mounting base 4 vertically, the inner tube 1 and outer tube 2 can be moved, thereby enabling product coating operations. The second end of the outer tube 2 is suspended, allowing for free placement and removal.
