Description

Technical Field

[0001] This application relates to the field of pressure pump technology, and more particularly to fully plastic elastic components with pressure-relieving properties. Background Technology

[0002] This section provides background information relevant to this application and is not necessarily prior art.

[0003] Some manufacturers of existing all-plastic push pumps have designed all-plastic elastic components that extend at an angle. These all-plastic elastic components consist of two ends and multiple support parts that are angled between the two ends. Because the support parts are connected on one side, the rebound force is large, requiring users to press harder, resulting in a poor user experience and poor spring stability. Summary of the Invention

[0004] One objective of this application is to solve the problem that the all-plastic spring used in a press pump has a single-sided support connection, resulting in a large rebound force and poor stability.

[0005] The technical solution provided in this application is as follows: A fully plastic elastic component with pressure-relieving properties includes multiple support portions, elastic connecting portions, a first end, and a second end; the multiple support portions are arranged adjacently with their ends staggered at an included angle, the elastic connecting portions connect the proximal ends of adjacent support portions, the elastic connecting portions are constructed with one or more clearance portions, the one or more clearance portions cause the elastic connecting portions of adjacent support portions to be divided into two or more connecting sub-parts; the first end and the second end are arranged at intervals and respectively connect the support portions at the two ends.

[0006] This application designs an elastic connecting part with a clearance portion, and the elastic connecting part is divided into two or more connecting sub-parts, thereby realizing multi-point connection of the support part at the proximal end, avoiding high rebound force and structural instability caused by single-sided connection; at the same time, the setting of the clearance portion reduces the overall stiffness of the elastic connecting part, making the pressing process gentler, improving the pressure relief characteristics and user experience.

[0007] In some embodiments, the clearance portion is generally square. A square shape facilitates injection molding, and the square structure effectively controls the deformation area of ​​the elastic connection, resulting in a more uniform stress distribution and further optimizing pressure relief performance and structural stability. Specifically, the clearance portion can be rectangular, with its length parallel to the arrangement direction of the support portion.

[0008] In other embodiments, the clearance portion is generally elliptical, and its length direction is parallel to the arrangement direction of the support portion.

[0009] In some embodiments, an arc-shaped transition portion is constructed on the inner side of the proximal end of adjacent supports, which can reduce stress concentration in the connection area, improve fatigue life, and make the deformation process smoother, thereby improving stress relief characteristics and structural reliability.

[0010] In some embodiments, the radius of the arc-shaped transition portion is 0.5 mm to 1.2 mm, which can effectively alleviate stress concentration and balance pressure relief performance with manufacturability.

[0011] In some embodiments, an arc-shaped transition portion is constructed on the inner side of the proximal end of the adjacent support portion, and a clearance portion is constructed with one such portion, and its two horizontal sidewalls are constructed with arc-shaped protrusions corresponding to the arc-shaped transition portion. The presence of one clearance portion and arc-shaped protrusions on the horizontal sidewalls corresponding to the arc-shaped transition portion makes the geometric transition between the elastic connection portion and the support portion more coordinated, further reducing local stiffness and improving overall elasticity and pressure relief effect.

[0012] In some embodiments, the support portion, the first end, and the second end are all annular structures, and the inner hole projections of the support portion, the first end, and the second end coincide along the axial angle between the first end and the second end. The annular structure and the coincidence of the inner hole projections along the axial direction ensure that the support portion, the first end, and the second end deform symmetrically and uniformly under axial force, improving the coaxial stability during the pressing process.

[0013] Another aspect of this application provides a fully plastic elastic component with pressure-relieving properties, comprising: multiple annular support portions, elastic connecting portions, and annular first and second ends; the multiple support portions are arranged adjacently with staggered ends at an included angle, and the elastic connecting portions connect the proximal ends of adjacent support portions. The elastic connecting portions are constructed with square or elliptical clearances, which divide the elastic connecting portions of adjacent support portions into two connecting sub-parts; the first and second ends are arranged parallel to each other, and the sides of the first and second ends are respectively connected to the distal ends of the support portions at the two ends. By using elastic connecting portions with square clearances to divide the connecting portion into two connecting sub-parts, and by connecting the annular first and second ends to the annular support portions respectively, a symmetrical and stable annular elastic structure is formed, effectively achieving double-sided or multi-sided connection, significantly reducing rebound force, and improving pressure-relieving performance and overall structural stability.

Detailed Implementation

[0015] The directional terms used in this application are merely for the convenience of describing the relative positional relationships between the components and do not limit the scope of protection. (See reference...) Figure 3 The x-direction is left and right, the y-direction is up and down, and the z-direction is forward and backward.

[0016] The technical solution of this application will be described below with reference to the accompanying drawings and specific embodiments.

[0017] See Figures 1 to 5 This application provides a fully plastic elastic component with pressure-relieving properties, comprising multiple support portions 1, elastic connecting portions 2, first end portions 3, and second end portions 4; the multiple support portions 1 are arranged adjacently with their ends staggered at an included angle, the elastic connecting portions 2 connect the proximal ends of adjacent support portions 1, and an arc-shaped transition portion 1.1 is constructed on the inner side of the proximal end of adjacent support portions 1; the elastic connecting portions 2 are constructed with one or more clearance portions 2.1, and the one or more clearance portions 2.1 divide the elastic connecting portions 2 of adjacent support portions 1 into two or more connecting sub-parts 2.2; the first end portion 3 and the second end portion 4 are arranged at intervals and respectively connect the support portions 1 at the two ends.

[0018] This application designs an elastic connecting part 2 with a clearance portion 2.1, and the elastic connecting part 2 is divided into two or more connecting sub-parts 2.2, thereby achieving multi-point connection of the support part 1 at the proximal end, avoiding the high rebound force and structural instability caused by unilateral connection; at the same time, the setting of the clearance portion 2.1 reduces the overall stiffness of the elastic connecting part 2, making the pressing process gentler, improving the pressure relief characteristics and user experience. The inner side of the proximal end of adjacent support parts 1 is constructed with an arc-shaped transition portion 1.1, which can reduce stress concentration in the connection area, improve fatigue life, and make the deformation process smoother, thereby improving the pressure relief characteristics and structural reliability.

[0019] In some embodiments, the all-plastic elastic component is integrally injection molded.

[0020] In some embodiments, the all-plastic elastic component is integrally injection molded from polypropylene (PP).

[0021] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the clearance portion 2.1 is square in shape. The square shape of the clearance portion 2.1 facilitates injection molding, and the square structure can effectively control the deformation area of ​​the elastic connection portion 2, making the stress distribution more uniform and further optimizing the pressure relief performance and structural stability.

[0022] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the clearance portion 2.1 is rectangular in shape, with its length direction parallel to the arrangement direction of the support portion 1. This design allows the elastic connection portion 2 to have greater flexible deformation capability along the arrangement direction when under pressure, effectively reducing the pressure intensity and enhancing the pressure relief effect.

[0023] In other embodiments, the clearance portion 2.1 is generally elliptical, with its length direction parallel to the arrangement direction of the support portion 1. This design allows the elastic connection portion 2 to have a more continuous and smooth flexible deformation capability along the arrangement direction of the support portion when under pressure. The elliptical structure can further reduce stress concentration, improve the pressure relief effect and fatigue life, while maintaining good molding processability.

[0024] See Figures 2 to 4 In some embodiments, the radius of the arc-shaped transition portion 1.1 is 0.5 mm to 1.2 mm. Within this range, stress concentration can be effectively alleviated, taking into account both pressure relief performance and manufacturability.

[0025] See Figures 2 to 4 In some embodiments, when an arc-shaped transition portion 1.1 is constructed on the inner side of the proximal end of an adjacent support portion 1, a clearance portion 2.1 is constructed with one clearance portion and arc-shaped protrusions 2.11 on its two horizontal sidewalls corresponding to the arc-shaped transition portion 1.1. The presence of one clearance portion 2.1 and arc-shaped protrusions 2.11 on the horizontal sidewalls corresponding to the arc-shaped transition portion 1.1 makes the geometric transition between the elastic connection portion 2 and the support portion 1 more coordinated, further reducing local stiffness and improving overall elasticity and pressure relief effect.

[0026] See Figure 1 , Figure 2 and Figure 5 In some embodiments, the support portion 1, the first end portion 3, and the second end portion 4 are all annular structures, and the inner hole projections of the support portion 1, the first end portion 3, and the second end portion 4 coincide along the axial angle between the first end portion 3 and the second end portion 4. The annular structure and the coincidence of the inner hole projections along the axial direction ensure that the support portion 1, the first end portion 3, and the second end portion 4 deform symmetrically and uniformly under axial force, improving the coaxial stability during the pressing process.

[0027] See Figures 1 to 5In other embodiments, each support portion 1, elastic connecting portion 2, first end portion 3, and second end portion 4 is annular; multiple support portions 1 are arranged adjacently with staggered ends at an angle, and the elastic connecting portion 2 connects the proximal ends of adjacent support portions 1. The elastic connecting portion 2 is constructed with a square clearance portion 2.1, which divides the elastic connecting portion 2 of adjacent support portions 1 into two connecting sub-parts 2.2; the first end portion 3 and the second end portion 4 are arranged parallel to each other, and the sides of the first end portion 3 and the second end portion 4 are respectively connected to the distal ends of the support portions 1 at the two ends. In this embodiment, by using multiple annular support portions 1 arranged adjacently with staggered ends at an angle, and cooperating with the elastic connecting portion 2 with the square clearance portion 2.1 to divide the connecting portion into two connecting sub-parts 2.2, and setting the annular first end portion 3 and the second end portion 4 arranged parallel to each other to connect to the distal ends of the support portions 1, a symmetrical and stable annular elastic structure is formed, which effectively realizes double-sided or multi-sided connection, significantly reduces rebound force, and improves pressure relief performance and overall structural stability.
