Description

Technical Field

[0001] The utility model relates to the technical field of lotion pumps, in particular to a limit structure for a lotion pump head and a main column to bounce up. Background Art

[0002] Lotion pump is a kind of liquid filling equipment widely used in cosmetics, skin care products and daily chemical products. Its function is to extract high-viscosity substances such as lotion, lotion, shampoo, etc. from the container and spray them out at a uniform speed. Lotion pump is generally divided into several parts such as nozzle, pump body and pipeline. Its structural design is both beautiful and practical. It also has the functions of preventing bacteria and leakage. The lotion pump on the market is mainly composed of pump head (or elbow), lock cover, metal spring, screw cover, body, main column, piston, sub-column and glass ball.

[0003] For example, the public document with application number 202020205304.2 discloses a limit structure for the pop-up of a lotion pump head and a main column. The utility model adopts a plastic spring made of plastic material and is placed under the main column to press the main column upward to realize the pop-up of the head and the main column. A lock cover is provided above the plastic spring to limit the pop-up height of the plastic spring, thereby limiting the pop-up height of the head and the main column, and preventing the plastic spring, the main column and the head from being pulled out of the body as a whole, thereby simplifying the structure of the lotion pump, making the lotion pump structure compact and beautiful, avoiding the use of metal, and easily meeting high standards of environmental protection requirements. It is also convenient to recycle and does not need to disassemble the parts for classified recycling. However, the limit structure for the pop-up of the lotion pump head and the main column can only perform the pop-up limit at a single position height according to the factory state during the limit process, and it is difficult to flexibly adjust the pop-up limit height according to the needs of different users in the later stage. The practicality and flexibility of use are both low, which is not conducive to on-demand use by people with different needs.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a limit structure for the emulsion pump head and the main column to pop up is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a limit structure for a lotion pump head and a main column to bounce up, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a limit structure for a lotion pump head and a main column pop-up, comprising a limit chamber, a toggle ring is rotatably arranged above the outer surface of the limit chamber through a bearing ring, an internal threaded barrel is fixedly installed below one end of the limit chamber, a threaded plate is threadedly connected to the inner surface of the internal threaded barrel, a main column tube body is slidably arranged in the middle of the surface of the threaded plate, four protrusions are evenly distributed around the surface of the main column tube body, and the protruding positions of the protrusions slide through the limit chamber and the threaded plate.

[0007] Preferably, a bottom plate is fixedly mounted on the lower end of the outer surface of the main column tube body, and a feeding pipe is slidably provided below the inner surface of the main column tube body through a piston seal.

[0008] Preferably, a thrust spring is sleeved below the surface of the bottom plate and fixedly installed on the periphery of the feeding tube, and the bottom end of the thrust spring is fixedly connected to the bottom of the inner surface of the limiting chamber.

[0009] Preferably, a pressing head is fixedly provided on the top end of the main column tube body, and an internal channel of the pressing head is connected to the main column tube body.

[0010] Preferably, a positioning ring is fixedly provided on the outer surface of the limiting chamber below the toggle ring, and positioning holes are evenly distributed above the surface of the positioning ring.

[0011] Preferably, a through hole is provided above the surface of the toggle ring, and the through hole is the same size as the positioning hole.

[0012] Preferably, a latch is slidably disposed inside the through hole, and the lower end of the latch is located inside the positioning hole at the corresponding position.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model arranges the toggle ring, the internal threaded tube, the threaded plate, the main column tube body and the protrusion, and the threaded plate can be adjusted up and down, and the limit position of the main column tube body can be flexibly adjusted, and the maximum limit height of the spring-up can be changed according to demand, so that the entire pump body can extrude quantitative materials as needed, which is more flexible to use and more practical;

[0015] 2. The utility model is provided with a bottom plate, a feeding tube, a thrust spring and a pressing head. By pressing the main column tube body with the pressing head, the bottom plate can be driven to move downward. Under the action of the pressure difference, the feeding tube is used to output the material. Then the thrust spring pushes the bottom plate to reset the main column tube body. The bottom plate is restricted by the upper threaded plate, that is, it moves up to the bottom of the threaded plate and stops moving upward, thereby completing the limit of the main column tube body bouncing up.

[0016] 3. The utility model arranges the positioning ring, the positioning hole, the through-hole and the latch, and after the toggle ring is rotated and the threaded plate is adjusted to the required position, the latch is passed through the through-hole and inserted into the positioning hole at the nearest point. When the positioning ring and the positioning hole are in the fixed position, the toggle ring is locked by the latch to prevent the toggle ring from rotating again due to external force, thereby greatly improving the stability of the limit position of the base plate after the threaded plate is adjusted.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 3 As shown, a limiting structure for a lotion pump head and a main column pop-up comprises a limiting chamber 1, a toggle ring 2 is rotatably provided above the outer surface of the limiting chamber 1 through a bearing ring, an internal threaded barrel 3 is fixedly installed below one end of the toggle ring 2 inside the limiting chamber 1, a threaded plate 4 is threadedly connected to the inner surface of the internal threaded barrel 3, a main column tube body 5 is slidably provided in the middle of the surface of the threaded plate 4, four protrusions 6 are evenly distributed around the surface of the main column tube body 5, and the protruding position of the protrusion 6 slides through the limiting chamber 1 and the threaded plate 4.

[0024] By adopting the above technical solution, rotating the dial ring 2 will drive the internal threaded tube 3 to rotate, and the penetration part of the limit chamber 1 and the protrusion 6 will prevent the main column tube body 5 from rotating. After the main column tube body 5 stops rotating, the protrusion 6 slides through the groove part of the threaded plate 4 so that the threaded plate 4 will not rotate with the rotation of the internal threaded tube 3. Therefore, when the internal threaded tube 3 rotates, the threaded plate 4 will move up and down, and the limit position of the main column tube body 5 can be flexibly adjusted, and the maximum limit height of the pop-up can be changed according to needs, so that the entire pump body can extrude and discharge quantitative materials as needed.

[0025] Furthermore, a bottom plate 7 is fixedly mounted on the lower end of the outer surface of the main column tube body 5, and a feeding pipe 8 is slidably provided below the inner surface of the main column tube body 5 through a piston seal.

[0026] By adopting the above technical solution, the bottom plate 7 and the threaded plate 4 are mutually limited, thereby controlling the maximum height of the main column tube body 5 bouncing up.

[0027] Furthermore, a thrust spring 9 is sleeved and fixedly installed on the outer periphery of the feeding tube 8 below the surface of the bottom plate 7 , and the bottom end of the thrust spring 9 is fixedly connected to the bottom of the inner surface of the limiting chamber 1 .

[0028] By adopting the above technical solution, the thrust spring 9 uses the bottom plate 7 to provide the main column tube body 5 with a force to bounce up.

[0029] Furthermore, a pressing head 10 is fixedly provided on the top end of the main column tube body 5 , and an internal channel of the pressing head 10 is communicated with the main column tube body 5 .

[0030] By adopting the above technical solution, the pressing head 10 is used to conveniently press down and push the main column tube body 5 to take out the material.

[0031] like Figure 1 and Figure 4 As shown, a positioning ring 11 is fixedly provided on the outer surface of the limiting chamber 1 below the toggle ring 2 , and positioning holes 12 are evenly distributed on the surface of the positioning ring 11 .

[0032] By adopting the above technical solution, the position of the positioning ring 11 is fixed, so that the positions of the positioning holes 12 are fixed, so as to achieve position fixation.

[0033] Furthermore, a through hole 13 is formed on the surface of the dial ring 2 , and the through hole 13 is the same size as the positioning hole 12 .

[0034] By adopting the above technical solution, the through hole 13 and the positioning hole 12 are of the same size, so that the through hole 13 can just correspond to any one of the positioning holes 12 .

[0035] Furthermore, a latch 14 is slidably disposed inside the through hole 13 , and the lower end of the latch 14 is located inside the positioning hole 12 at the corresponding position.

[0036] By adopting the above technical solution, the latch 14 passes through the through hole 13 and is inserted into the positioning hole 12 , so that the fixed position of the positioning ring 11 is transmitted to the toggle ring 2 through the latch 14 , and the toggle ring 2 is locked.

[0037] Working principle: When using the lotion pump head and the limiting structure of the main column pop-up, first, according to the requirement of the rebound height position of the main column tube body 5, the positioning is performed, and the rotation of the dial ring 2 will drive the internal threaded tube 3 to rotate. The penetration part of the limiting chamber 1 and the protrusion 6 prevents the main column tube body 5 from rotating. After the main column tube body 5 does not rotate, the protrusion 6 slides through the groove part of the thread plate 4 so that the thread plate 4 does not rotate with the rotation of the internal threaded tube 3. Therefore, when the internal threaded tube 3 rotates, the thread plate 4 moves up and down, and the limiting position of the main column tube body 5 pops up is flexibly adjusted. After the thread plate 4 is adjusted to the required position, the latch 1 is inserted. 4 passes through the through hole 13 and is inserted into the positioning hole 12 at the nearest point. Under the fixed position of the positioning ring 11 and the positioning hole 12, the toggle ring 2 is locked by the latch 14, and then the main column tube body 5 is pressed down by the pressing head 10 to drive the bottom plate 7 to move down. Under the action of the pressure difference, the feeding pipe 8 is used to feed and output, and then the thrust spring 9 pushes the bottom plate 7 to reset the main column tube body 5, and the bottom plate 7 is limited by the upper threaded plate 4, that is, the bottom plate 7 stops moving up after moving up to the bottom of the threaded plate 4 to fit, thereby completing the limit of the main column tube body 5 popping up. This is the working principle of the limit structure of the lotion pump head and the main column popping up.
