[0002] As an important sealing component of the cam lock joint, the sealing ring plays an important role in the sealing performance of the cam lock joint. In actual use, since the sealing of the sealing ring requires a certain extrusion force, when the sealing ring is installed in the sealing groove, the outer peripheral wall of the sealing ring protrudes from the inner peripheral wall of the female head. When the male head is inserted, the sealing ring will be compressed and deformed to achieve a sealing effect. However, the protruding part of the sealing ring not only brings greater resistance to the installation and insertion of the male head, resulting in difficulties in the installation and removal of the male head, but also easily causes cutting of the sealing ring, which can easily lead to damage to the sealing ring, thereby reducing the service life of the sealing ring and the sealing performance of the cam lock joint.

[0020] See also Figure 1-Figure 3, a sealing structure of a cam lock joint shown in the figure, comprises a female body 101 and a male body 102 which are plugged into each other, a sealing groove 103 is formed on the inner wall of the female body 101, a rubber sealing ring 104 is arranged in the sealing groove 103, and a contraction mechanism is arranged in the sealing groove 103 for contracting the rubber sealing ring 104;

[0021] The shrinking mechanism includes a mounting ring 201 slidably connected in the sealing groove 103, a shrinking ring 202 is fixedly connected to one side of the mounting ring 201 close to the rubber sealing ring 104, a first inclined surface 203 is provided on one side of the rubber sealing ring 104 close to the shrinking ring 202, the other end of the shrinking ring 202 slides on the first inclined surface 203, and a driving mechanism for driving the shrinking ring 202 is provided on the female body 101;

[0022] It should be noted here that: through the setting of the contraction mechanism, under the driving action of the driving mechanism, the driving force is used to expand and deform the rubber sealing ring 104 toward the inner wall of the sealing groove 103, thereby reducing the protrusion of the outer peripheral wall of the rubber sealing ring 104 in the connecting channel of the female head body 101, thereby further reducing the resistance of the male head body 102 during the installation and insertion process and the cutting edge damage to the rubber sealing ring 104, thereby ensuring the connection sealing between the male head body 102 and the female head body 101 while improving the convenience of plugging in the male head body 102 and the service life of the rubber sealing ring 104.

[0023] It is worth noting that: as a prior art, the specific structure and working principle of the cam lock have been mastered by people in this field, and will not be elaborated here.

[0024] Please refer to the figure Figure 2 and Figure 3 In the sealing groove 103 shown in the figure, a guide assembly for guiding the movement of the mounting ring 201 is provided, and the guide assembly is a T-shaped rod 3, one end of the T-shaped rod 3 is fixedly connected to the inner wall of the sealing groove 103 away from the rubber sealing ring 104, and the mounting ring 201 slides on the side wall of the T-shaped rod 3;

[0025] It should be noted here that: by setting the guide component, a guiding and limiting function is provided for the movement of the shrink ring 202.

[0026] Please refer to the figure Figure 2 and Figure 3 , a first spring 4 is sleeved on the side wall of the T-shaped rod 3 shown in the figure, and both ends of the first spring 4 are respectively connected to the inner wall of the sealing groove 103 and the mounting ring 201;

[0027] It should be noted here that: through the setting of the first spring 4, after the male body 102 is inserted, the elastic force of the first spring 4 releases the shrinkage push of the shrink ring 202 on the rubber sealing ring 104. At this time, the rubber sealing ring 104 is against the side wall of the male body 102 under the action of its own elasticity, thereby ensuring the connection sealing between the male body 102 and the female body 101.

[0028] Please refer to the figure Figure 2 and Figure 3 , there are multiple guide assemblies in the figure, and each guide assembly is arranged in a ring array;

[0029] It should be noted here that: the guiding and limiting effect of the mounting ring 201 is improved by means of a plurality of guide components arranged in a ring array.

[0030] Working principle: When the male body 102 and the female body 101 are connected, in order to prevent the rubber sealing ring 104 from hindering the installation of the male body 102, the rubber sealing ring 104 needs to be shrunk. During the shrinking process of the rubber sealing ring 104, the shrinking ring 202 at one end of the installation ring 201 is pushed to move close to the rubber sealing ring 104 through the driving mechanism. When the shrinking ring 202 and the rubber sealing ring 104 are against each other, under the interaction of the first inclined surface 203, the rubber sealing ring 104 is expanded and deformed toward the inner wall of the sealing groove 103 through the driving force, thereby reducing the protrusion of the outer peripheral wall of the rubber sealing ring 104 in the connecting channel of the female body 101, thereby further reducing the resistance of the male body 102 during the installation and insertion process and the cutting edge damage caused to the rubber sealing ring 104, thereby improving the convenience of plugging the male body 102 and the service life of the rubber sealing ring 104;

[0031] After the male body 102 is inserted, the elastic force of the first spring 4 releases the shrinkage push of the shrink ring 202 on the rubber sealing ring 104. At this time, the rubber sealing ring 104 abuts against the side wall of the male body 102 under its own elastic action, thereby ensuring the connection sealing between the male body 102 and the female body 101.

[0032] Example 2

[0033] See also Figure 2 and Figure 3 This embodiment further explains Example 1. The driving mechanism shown in the figure includes a driving rod 501 slidably connected to the female body 101. One end of the driving rod 501 is fixedly connected to a driving plate 502. A second inclined surface 503 is provided on the side of the mounting ring 201 away from the rubber sealing ring 104. The other end of the driving rod 501 slides on the second inclined surface 503.

[0034] It should be noted here that: through the setting of the driving mechanism, when the driving plate 502 is pressed, the driving rod 501 will be pushed to move closer to the mounting ring 201 under the action of force. When one end of the driving rod 501 is against the mounting ring 201, the mounting ring 201 will be pushed to move under the interaction force of the second inclined surface 503 and the guiding action of the guide assembly.

[0035] Please refer to the figure Figure 2 and Figure 3 , a second spring 504 is sleeved on the side wall of the driving rod 501 shown in the figure, and the two ends of the second spring 504 are respectively connected to the side wall of the driving plate 502 and the female body 101;
