Description

Technical Field

[0001] This invention relates to the field of connecting fittings technology, and more specifically to a highly stable connecting end cap. Background Technology

[0002] Connecting end caps are used to connect and secure two parts, so they need to be very stable and prevent loosening during connection. Nylon material is characterized by high strength and good resilience, and also has outstanding advantages in wear resistance and fatigue resistance, making it a common choice for connecting end caps.

[0003] In the prior art, such as the end cap disclosed in Chinese patent CN 213425899 U, the injection molded body and the end cap body are directly connected and are not easy to shake or separate. However, during the assembly process, because the entire connection part is centrally symmetrical, it is easy to install it backwards or incorrectly, which can easily lead to adverse consequences. Summary of the Invention

[0004] The purpose of this invention is to provide a highly stable connecting end cap, which solves the problems of insufficient connection stability and easy incorrect installation of end caps in the prior art.

[0005] A highly stable connection end cap includes: a first connecting part, a second connecting part, and a fixing part, wherein the first connecting part and the second connecting part are connected to both sides of the fixing part, the first connecting part is a cylinder, the fixing part is a cylinder, and the second connecting part is a cone.

[0006] Preferably, the first connecting part, the second connecting part, and the fixing part are integrally formed.

[0007] Preferably, the material of the connecting end cap is nylon.

[0008] Preferably, the diameter of the first connecting part is smaller than the diameter of the second connecting part fixing part, the end of the second connecting part with the smaller conical diameter is connected to the fixing part, and the diameter of the end of the second connecting part with the smaller conical diameter is smaller than the diameter of the fixing part.

[0009] Preferably, the first connecting portion has a first protrusion and a second protrusion, both of which are arc-shaped. The first and second protrusions form a snap-fit ​​structure to secure the parts.

[0010] Preferably, the outer side of the first protrusion has a positioning post.

[0011] Preferably, the second protrusion has a guide groove. The guide groove allows for smoother insertion into the first connecting part, while also distinguishing it from the first protrusion, thus forming a mistake-proofing mechanism to prevent the part from being installed backwards.

[0012] Preferably, the first connecting part has a window on its side, and a guide rib is provided inside the window. The cross-section of the guide rib is a parallelogram. The parallelogram guide rib makes the assembly of the parts smoother and more secure, and also has a mis-proof function to prevent assembly deviations and misassemblies.

[0013] Preferably, the second connecting part has a gear hole with a positioning edge. The positioning edge makes the gear hole assembly more stable, and the product is not easy to fall off after assembly. It also has a misalignment prevention function, so that there will be no situation where it is not installed properly or incorrectly when assembling with the other parts.

[0014] Preferably, the second connecting part has multiple arc-shaped connecting grooves on its end face, and the connecting grooves are on the same circle.

[0015] Preferably, there is a notch between the connecting grooves, and a positioning hole is provided at the notch.

[0016] Preferably, the outer side of the second connecting part has threads.

[0017] Beneficial effects:

[0018] 1. This invention provides a highly stable connecting end cap, which has higher stability and is not easy to install incorrectly, thus improving the efficiency and accuracy of assembly.

[0019] 2. The first connecting part is provided with a first protrusion and a second protrusion, which form a snap-fit ​​structure. The elasticity of the nylon material itself can secure the joint, and the guide rib can further enhance the stability of the connection. At the same time, the first connecting part is a cylinder with an axisymmetric structure, which makes it easy to install the joint incorrectly. To prevent incorrect installation, a guide groove is provided on the second protrusion. The guide groove can help guide the joint to be inserted more smoothly and prevent the incorrectly oriented part from being inserted when installed incorrectly, thus playing a role in preventing errors.

[0020] 3. Guide ribs are provided on both sides of the first protrusion. The cross-section of the guide ribs is a parallelogram. The corners of the parallelogram can increase the stability of the handpiece after it is inserted and prevent it from shaking. At the same time, if the handpiece is installed backwards, it will not be able to be inserted because of the different angles of the parallelogram, thus playing a role in preventing mistakes.

[0021] 4. The second connecting part has a gear hole with gear-like protruding teeth. When the handpiece is inserted, the protruding teeth will engage with the handpiece, increasing the stability of the connection. At the same time, the second connecting part has an axisymmetric structure. When connecting the handpiece to the gear hole, the wrong orientation may be installed. Therefore, a positioning edge is provided on one side of the gear hole to quickly find the installation orientation.

[0022] 5. The end face of the second connecting part has multiple arc-shaped connecting grooves, which, together with a positioning hole between the connecting grooves, can effectively improve the stability of the connection. At the same time, the positioning hole is used for positioning to prevent parts from being installed backwards or incorrectly. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of conflict, the definitions in this specification shall prevail.

[0031] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1:

[0033] like Figure 1-5 The high-stability connection end cap shown includes: a first connecting part 1, a second connecting part 2 and a fixing part 3. The first connecting part 1 and the second connecting part 2 are connected to both sides of the fixing part 3. The first connecting part 1 is a cylinder, the fixing part 3 is a cylinder, and the second connecting part 2 is a cone.

[0034] The first connecting part 1, the second connecting part 2, and the fixing part 3 are integrally molded from nylon material by injection molding.

[0035] The diameter of the first connecting part 1 is smaller than the diameter of the second connecting part 2 and the fixing part 3. The end of the second connecting part 2 with the smaller conical diameter is connected to the fixing part 3. The diameter of the end of the second connecting part 2 with the smaller conical diameter is smaller than the diameter of the fixing part 3.

[0036] The first connecting part 1 has a first protrusion 11 and a second protrusion 12, both of which are arc-shaped. The first protrusion 11 has a positioning post 13 on its outer side, and the second protrusion 12 has a guide groove 14. The first protrusion 11 and the second protrusion 12 form a snap-fit ​​structure to secure the part. The positioning post 13 connects with the matching part, further enhancing the stability of the connection. The guide groove 14 allows for smoother insertion into the first connecting part 1 and also provides a distinction from the first protrusion 11, forming a mistake-proofing mechanism to prevent the part from being installed backwards.

[0037] The first connecting part 1 has a window on one side, and a guide rib 15 is installed inside the window. The cross-section of the guide rib 15 is a parallelogram. The parallelogram guide rib 15 makes the assembly of the parts smoother and more secure, and also has a mis-proof function. Only when the direction is correct can the part pass through the guide rib 15, preventing assembly deviation and mis-assembly.

[0038] The second connecting part 2 has a gear hole 21 with a positioning edge 22. The positioning edge 22 makes the gear hole 21 more stable and the product is less likely to fall off after assembly. It also has a misalignment prevention function, so that there will be no misalignment or incorrect assembly when assembling with other parts.

[0039] The second connecting part 2 has multiple arc-shaped connecting grooves 23 on its end face. The connecting grooves 23 are on the same circle, and there is a notch between the connecting grooves 23. A positioning hole 24 is provided at the notch. The outer side of the second connecting part 2 has threads 25. The connecting grooves 23 and the positioning hole 24 are used to connect with the counterpart component, further improving the stability of the connection with the counterpart component.
