Description

Technical Field

[0001] The utility model belongs to the technical field of piston pins, and particularly relates to a combined piston pin. Background Art

[0002] The piston pin is a cylindrical pin mounted on the piston skirt. Its center passes through the connecting rod's small end hole, connecting the piston and connecting rod. Its function is to transmit the gas force exerted on the piston to the connecting rod, or to enable the small end of the connecting rod to move the piston. To reduce weight, the piston pin is generally made of high-quality alloy steel and is hollow.

[0003] Authorization publication number "CN 204784667 U" records "a combined piston pin" including an alloy steel sleeve and an aluminum alloy inner pin. The aluminum alloy inner pin is inserted into the alloy steel sleeve, and the outer wall of the aluminum alloy inner pin contacts the alloy steel sleeve. The end face of the aluminum alloy inner pin and the outer wall of the aluminum alloy inner pin are connected together through a chamfered surface. This structure reduces the deformation of the pin body and the wear of the pin hole.

[0004] The above patent can achieve a relatively light weight of the piston pin, reduce the inertial force of the reciprocating motion, and reduce energy loss, but the above patent cannot quickly connect one piston section with another piston section. During actual operation, personnel need to rely on other tools to connect the two piston pins, which is relatively inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a combined piston pin, aiming to solve the problem in the prior art that during actual operation, personnel need to rely on other tools to connect two piston pins, which is relatively inconvenient.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a combined piston pin, comprising:

[0007] piston pin body;

[0008] A second groove is formed on the circumferential surface of the piston pin body;

[0009] a plurality of springs, wherein the plurality of springs are disposed in the second groove;

[0010] A clamping block is fixedly connected to one side end of the plurality of springs.

[0011] As a preferred solution of the present invention, a linking collar is provided on the circumferential surface of the piston pin body, and two circular holes are provided on the circumferential surface of the linking collar.

[0012] As a preferred solution of the present invention, a first groove is provided on one side end of the piston pin body, and a rubber ring is provided on the circumferential surface of the piston pin body.

[0013] As a preferred solution of the present invention, the rubber ring is fitted with the linking ring, and a thread groove is provided on one side end of the piston pin body.

[0014] As a preferred solution of the present invention, the material of the rubber ring is sealing rubber made of polyurethane material.

[0015] As a preferred solution of the present invention, the material of the linking ring is a connecting ring made of alloy steel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this solution, when a person uses this device, he connects the external device to the piston pin body through a thread, and at the same time, he rotates the linking collar. The circumferential surface of the linking collar is provided with a groove of the same size as the card block. When the person rotates it to the appropriate position, the card block will pop out of the spring due to the elastic force of the multiple second grooves, and then be stuck in the groove provided on the circumferential surface of the linking collar, and then the installation is completed. Please note that the linking collar body shown in the figure is only a part. The linking collar is an existing device that needs to be docked with this device. By using this device, the traditional piston pin assembly fails to achieve the quick installation function, making the installation process time-consuming and labor-intensive, thereby affecting the efficiency of the device. In contrast, this device not only has the characteristics of quick installation, but also does not require the use of external auxiliary tools during the installation process. The docking installation process is simple and quick, which greatly improves work efficiency.

[0018] 2. In this solution, personnel can connect the piston pin body to other devices through the connecting ring. At the same time, the two circular holes can be used to reduce weight, effectively reducing the overall mass of the piston pin body, thereby reducing inertia force and improving engine response speed and fuel economy.
