Abstract
Description
Technical Field
[0001] This invention belongs to the field of spring technology, and in particular to a plastic spring. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. The main types include helical springs, spiral springs, leaf springs, and irregularly shaped springs.
[0003] Traditional springs are usually made of metal. Cosmetic pumps need to use springs to provide elastic thrust so that the pump body is reset after being pressed, and to dispense the liquid or cream of the cosmetic. Metal springs are more elastic, feel harder, and have a poorer user experience. Summary of the Invention
[0004] The purpose of this invention is to provide a plastic spring to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic spring, comprising:
[0006] Elastic component one includes a plastic fixing ring, a plastic connecting ring, and several plastic upper elastic components. Several elastic plastic upper elastic components arranged at equal intervals in a U-shape are disposed on the bottom surface of the plastic fixing ring. The several plastic upper elastic components are vertical.
[0007] Elastic component two includes a plastic support ring, a plastic connecting ring, and several lower plastic elastic components. The plastic support ring is located below the plastic fixing ring. Several elastic lower plastic components, arranged at equal intervals in an inverted U-shape, are disposed on the top surface of the plastic support ring. The number of lower plastic elastic components is equal to the number of upper plastic elastic components, and the upper plastic elastic components and lower plastic elastic components are arranged alternately. Plastic connecting rings are disposed adjacent to the upper plastic elastic components and the lower plastic elastic components.
[0008] A plastic spring, comprising:
[0009] Elastic component three includes a plastic fixing ring and a plastic connecting ring, as well as several elastic plates one. Several elastic plates one arranged at equal intervals in a U-shape are disposed on the bottom surface of the plastic fixing ring. Several elastic plates one are inclined.
[0010] Elastic component four includes a plastic support ring, a plastic connecting ring, and several elastic plates two. Several elastic plates two arranged at equal intervals in an inverted U-shape are disposed on the top surface of the plastic support ring. The number of elastic plates two is equal to the number of elastic plates one, and the number of elastic plates one and elastic plates two are arranged opposite to each other. Plastic connecting rings are disposed on the adjacent sides of the number of elastic plates one and elastic plates two.
[0011] Preferably, a plurality of plastic upper elastic elements are arranged in a ring shape, and a plastic connecting ring is disposed on the adjacent side of the plastic fixing ring and the plastic support ring.
[0012] Preferably, the diameter of the plastic connecting ring is larger than the diameter of the plastic fixing ring and the plastic support ring.
[0013] Preferably, the top and bottom surfaces of the plastic connecting ring are fixedly connected to a number of upper and lower plastic elastic elements, respectively.
[0014] Preferably, the bottom surfaces of several lower plastic elastic elements are fixedly connected to the plastic support ring, and the top surfaces of several upper plastic elastic elements are fixedly connected to the plastic fixing ring.
[0015] Preferably, a number of lower plastic elastic elements are arranged in a ring shape.
[0016] Preferably, several elastic plates 1 and 2 are inclined, and several elastic plates 1 and 2 are respectively disposed at the top and bottom of the plastic connecting ring.
[0017] Compared with the prior art, the technical effects and advantages of the present invention are as follows:
[0018] This plastic spring is used in the pump body for dispensing cosmetics. A spring is needed to provide elastic thrust so that the pump body can be reset and the cosmetics can be pumped out. Metal springs have a large elastic thrust, but the pressing feel is hard and the experience is poor. The plastic spring has a small elastic thrust, a soft pressing feel, and a good experience.
[0019] This plastic spring is suitable for use in the pump body of cosmetics. By compressing the spring, the distance between the plastic fixing ring and the plastic support ring is shortened. Under the connection provided by the plastic connecting ring, the U-shaped upper plastic elastic element and the lower plastic elastic element, or the elastic plate one and the elastic plate two, undergo plastic deformation. After the compression of the spring is released, the upper plastic elastic element and the lower plastic elastic element, or the elastic plate one and the elastic plate two, elastically reset, realizing the elastic function of the plastic spring and thus improving the practicality of the plastic spring.

However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.
[0030] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this invention, and are explained here together.
[0031] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0032] To address the issue of excessive elastic force, a stiff feel, and a poor user experience when using plastic springs in cosmetic pump bodies, please refer to [link to relevant documentation]. Figures 1 to 6 The structure of the device body includes:
[0033] Elastic component 6 includes a plastic fixing ring 1, a plastic connecting ring 3, and several plastic upper elastic components 2. Several U-shaped, equidistantly arranged elastic plastic upper elastic components 2 are disposed on the bottom surface of the plastic fixing ring 1. The several plastic upper elastic components 2 are vertical. The several plastic upper elastic components 2 located on the bottom surface of the plastic fixing ring 1 are arranged in a circular shape by rotating and tilting at equal angles. The two pillars of the plastic upper elastic components 2 are not arranged and extended along the straight direction of the X-axis or Y-axis, so that the two pillars of the plastic upper elastic components 2 are arranged along the circular direction of the plastic fixing ring 1.
[0034] Elastic component 2 7 includes a plastic support ring 5, a plastic connecting ring 3, and several lower plastic elastic components 4. The plastic support ring 5 is located below the plastic fixing ring 1. Several elastic lower plastic elastic components 4, arranged at equal intervals in an inverted U-shape, are disposed on the top surface of the plastic support ring 5. The several lower plastic elastic components 4 are arranged at equal intervals along the top surface of the circular ring of the plastic support ring 5, enabling the several lower plastic elastic components 4 to rotate and tilt sequentially at equal angles. At the same time, the lower plastic elastic components 4 have an arc shape laterally. The number of the several lower plastic elastic components 4 is equal to that of the several upper plastic elastic components 2. Furthermore, several upper plastic elastic components 2 and several lower plastic elastic components 4 are arranged alternately, and plastic connecting rings 3 are provided on the adjacent sides of several upper plastic elastic components 2 and several lower plastic elastic components 4. This allows the plastic fixing ring 1, plastic connecting ring 3, plastic support ring 5, several upper plastic elastic components 2, and several lower plastic elastic components 4 to form a cylindrical structure. To adapt to the usage requirements of the spring, the elastic component 1 6 and elastic component 2 7 can be used individually, and at the same time, elastic component 1 6 and elastic component 2 7 can be used in multiple layers.
[0035] include:
[0036] Elastic component 3 10 includes a plastic fixing ring 1, a plastic connecting ring 3, and several elastic plates 8. Several elastic plates 8 arranged at equal intervals in a U-shape are disposed on the bottom surface of the plastic fixing ring 1. The elastic plates 8 are inclined.
[0037] Elastic component four 11 includes a plastic support ring 5, a plastic connecting ring 3, and several elastic plates two 9. Several elastic plates two 9 arranged at equal intervals in an inverted U-shape are disposed on the top surface of the plastic support ring 5. The number of elastic plates two 9 is equal to the number of elastic plates one 8, and the elastic plates one 8 are arranged opposite to the elastic plates two 9. The plastic connecting ring 3 is disposed adjacent to the elastic plates one 8 and elastic plates two 9. The elastic plates one 8 are disposed adjacent to the plastic fixing ring 1 and the plastic connecting ring 3. The difference between elastic plate 1 8 and upper plastic elastic component 2 is that upper plastic elastic component 2 is in a vertical state, while elastic plate 1 8 is tilted. The tilt angle of elastic plate 1 8 is determined according to the usage requirements. The difference between elastic plate 2 9 and lower plastic elastic component 4 is that lower plastic elastic component 4 is in a vertical state, while elastic plate 2 9 is tilted. The tilt angle of elastic plate 2 9 is determined according to the usage requirements. Elastic component 3 10 and elastic component 4 11 can be used individually, and multiple layers of elastic component 3 10 and elastic component 4 11 can be stacked together.
[0038] A number of upper plastic elastic elements 2 are arranged in a ring shape. A plastic connecting ring 3 is located on the adjacent side of the plastic fixing ring 1 and the plastic support ring 5. The diameter of the plastic connecting ring 3 is larger than the diameter of the plastic fixing ring 1 and the plastic support ring 5. The top and bottom surfaces of the plastic connecting ring 3 are fixedly connected to a number of upper plastic elastic elements 2 and lower plastic elastic elements 4, respectively. The bottom surfaces of the lower plastic elastic elements 4 are fixedly connected to the plastic support ring 5. The top surfaces of the upper plastic elastic elements 2 are fixedly connected to the plastic fixing ring 1. The lower plastic elastic elements 4 are arranged in a ring shape. A number of elastic plates 1 and 2 are inclined. The elastic plates 1 and 2 are located at the top and bottom of the plastic connecting ring 3, respectively. The overall spring structure is obtained by injection molding.
[0039] Working principle
[0040] When the inclined elastic plate 8 and elastic plate 9 are used, the plastic spring is pressed vertically, the distance between the plastic fixing ring 1 and the plastic support ring 5 is shortened, and under the connection provided by the plastic connecting ring 3, the elastic plate 8 and elastic plate 9 are squeezed, so that the elastic plate 8 and elastic plate 9 undergo plastic deformation.
[0041] When vertical plastic upper elastic element 2 and plastic lower elastic element 4 are used, the plastic spring is pressed vertically, the distance between plastic fixing ring 1 and plastic support ring 5 is shortened, and under the connection provided by plastic connecting ring 3, plastic upper elastic element 2 and plastic lower elastic element 4 are squeezed and plastically deformed.
