[0016] The utility model will be described in detail in combination with the drawings and examples. Example
[0017] A kind of sealing exhaust pipe gasket, such as Figure 1 And Figure 2As shown, including the gasket body 1, the gasket body 1 is provided with mounting hole 2, the inner wall of mounting hole 2 is provided with positioning ring 3, the outer diameter of positioning ring 3 is equal to the inner diameter of mounting hole 2, the connection between positioning ring 3 and mounting hole 2 is provided with easy broken groove 4, further, positioning ring 3 is made of brittle plastic, specifically, the brittle plastic is polystyrene, due to the design of positioning ring 3, its outer diameter is equal to the inner diameter of mounting hole 2, which makes the gasket tightly fit on the inner wall of mounting hole 2 of the cylinder body during installation, thereby effectively preventing the gasket from moving or misplacing during installation, which greatly enhances the stability and accuracy of gasket installation, by setting easy broken groove 4, people can pass the screw through the mounting hole 2 on the gasket body 1 and the mounting hole 2 on the cylinder body in turn after installing other parts in turn, at this time the screw will abut against the positioning ring 3, with the continuous rotation of the screw, the positioning ring 3 and the gasket body 1 are broken, the positioning ring 3 falls into the mounting hole 2 in the cylinder body, thereby completing the installation operation, through the above setting, the positioning ring 3 can play the effect of pre-positioning, the mounting hole 2 and the mounting hole 2 are not easy to misplace, so that people can install the gasket more stably, quickly and efficiently, save the installation time, and the brittleness of polystyrene is large, which is easy to be broken by external force impact, thereby facilitating people to break the positioning ring 3, facilitating the subsequent screwing of the screw, at the same time, it has good processing performance, which can be easily processed into the required shape and size through injection molding, extrusion and other molding processes, reducing the production cost.
[0018] As Figure 1 and Figure 2 shown, the positioning ring 3 is vertically arranged on one side of the gasket body 1 and the end of the positioning ring 3 away from the gasket body 1 is provided with a circular arc part 7, the vertically arranged positioning ring 3 can ensure the accurate positioning of the gasket during installation, since the positioning ring 3 can be embedded into the mounting hole 2 on the cylinder body, it provides a clear reference point, so that the installer can easily identify and install the gasket, which helps to maintain the stability of the gasket during installation, ensures the correct installation position and sealing performance, at the same time, the vertically arranged positioning ring 3 makes the gasket easier to be installed to the predetermined position, the installer only needs to place the gasket on the cylinder body, and then ensure that the positioning ring 3 tightly fits with the inner wall of the mounting hole 2, which simplifies the installation process and saves the installation time, the design of the circular arc part 7 can be used as a guide during installation, helping the installer to more easily align the positioning ring 3 with the mounting hole 2 on the cylinder body, during installation, the circular arc part 7 can guide the positioning ring 3 to smoothly enter the mounting hole 2, reducing the friction and resistance during installation, thereby improving the installation efficiency.
[0019] As Figure 1 and Figure 2As shown, the positioning ring 3 is provided with a ring groove 5 on the side close to the breakable groove 4, and a plurality of through holes 6 are provided on the positioning ring 3 and communicated with the ring groove 5 and the breakable groove 4, and further, the plurality of through holes 6 are circumferentially arranged on the positioning ring 3, and the maximum distance between the two symmetrically arranged through holes 6 is equal to the inner diameter of the mounting hole 2. By providing the through holes 6 on the positioning ring 3, the through holes 6 are communicated with the ring groove 5 and the breakable groove 4, so that during the installation process, when the breakable groove 4 needs to be broken, the through holes 6 can be used as a stress concentration area to promote the breakage of the breakable groove 4. This design can more reliably control the breakage of the breakable groove 4, ensure that the gasket can be correctly installed in the expected manner, and improve the installation efficiency of the gasket. Since the maximum distance between the two symmetrically arranged through holes 6 is equal to the inner diameter of the mounting hole 2, when the positioning ring 3 breaks, the residual part left on the gasket will be less, thereby facilitating the subsequent screwing of the screw, and the design of the ring groove 5 can weaken the overall strength of the positioning ring 3, thereby facilitating the subsequent control of the breakage of the positioning ring 3 and improving the operation efficiency.
