The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0025] According to an exemplary embodiment of the present disclosure, referring to Figures 1 to 4 As shown, a valve core disassembly and assembly device for an airbag expansion tank is provided, the valve core disassembly and assembly device comprising: a mounting rod 1, the mounting rod 1 comprising a gripping end 11 and a mounting end 12 arranged opposite to each other; two clamping jaws 2, the two clamping jaws 2 are connected to the mounting end 12; and a control mechanism 4, the control mechanism 4 is installed on the mounting rod 1, and is used to control the two clamping jaws 2 to move closer to or away from each other.

[0026] Through the above technical scheme, in the valve core disassembly and assembly device for the airbag expansion tank provided in the present invention, the mounting rod includes a relative holding end and a mounting end, the holding end is for the operator to hold, and the two clamping claws are connected to the mounting end of the mounting rod, and the two clamping claws are controlled by the control mechanism to move closer to or away from each other, so as to achieve the clamping and fixing of the valve core. Compared with the method of fixing the valve core by holding it with hands, the operator only needs to hold the holding end of the mounting rod and operate the control mechanism, so that the valve core can be disassembled and assembled at the opening 102 of the airbag expansion tank, which reduces the difficulty of operation, saves time and effort, and improves the disassembly and assembly efficiency of the valve core and the reliability of installation.

[0027] In the present disclosure, the mounting rod 1 can be configured as a telescopic rod. By configuring in this way, the user can adjust the length of the mounting rod 1 according to the use requirements, so as to adapt to airbag expansion tanks of different depth specifications, and the use is more flexible and convenient. In order to facilitate hand holding, a grip 111 can be provided at the gripping end 11, and the grip 111 is perpendicular to the mounting rod 1 to facilitate subsequent operations.

[0028] According to an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 As shown in , the valve core disassembly and assembly device may include a sleeve 3, which is slidably mounted on the mounting rod 1 along the extension direction of the mounting rod 1, and the sleeve 3 is provided with a mounting hole 32, the aperture of the mounting hole 32 gradually decreases from the mounting rod 1 to the direction of the clamping jaws 2, and the two clamping jaws 2 are arranged in the mounting hole 32, and the control mechanism 4 is used to drive the sleeve 3 to move along the extension direction of the mounting rod 1, so that the two clamping jaws 2 are close to or away from each other. Through the above technical solution, when the control mechanism 4 drives the sleeve 3 to move back and forth along the extension direction of the mounting rod 1, the sleeve 3 also moves along the extension direction of the two clamping jaws 2, so that the hole wall of the mounting hole 32 squeezes the part in contact with the two clamping jaws 2, so that the two clamping jaws 2 are close to or away from each other, and the valve core 101 is clamped and fixed or the valve core 101 is clamped and released.

[0029] According to an exemplary embodiment of the present disclosure, referring to Figure 2 As shown in the figure, the sleeve 3 can also be provided with a connecting hole 31 connected to the mounting hole 32, the aperture of the connecting hole 31 is adapted to the mounting rod 1, and the hole wall of the connecting hole 31 is in contact with the mounting rod 1. Through such an arrangement, the installation of the sleeve 3 is facilitated and the reliability of the connection between the sleeve 3 and the mounting rod 1 is improved.

[0030] According to an exemplary embodiment of the present disclosure, referring to Figure 1 As shown in , the control mechanism 4 may include an operating rod 41, a reset member 42 and a brake line 43. The operating rod 41 is arranged near the gripping end 11 and is slidably connected to the mounting rod 1. The brake line 43 is used to connect the operating rod 41 and the sleeve 3. The reset member 42 is arranged between the operating rod 41 and the brake line 43 and is used to reset the operating rod 41. Through the above technical solution, when the operating rod 41 is operated to move toward the gripping end 11, the operating rod 41 pulls the sleeve 3 under the action of the brake line 43, so that the sleeve 3 also moves toward the gripping end 11. The movement of the sleeve 3 toward the gripping end 11 causes the hole wall of the mounting hole 32 to squeeze the two clamping jaws 2, so that the two clamping jaws 2 are close to each other. When the operating rod 41 is released, the elastic force of the reset member 42 moves the operating rod 41 toward the mounting end 12, releasing the brake line 43, causing the sleeve 3 to lose traction and slide away from the gripping end 11, so that the mounting hole 32 reduces the squeezing of the two clamping jaws 2 to loosen the clamping of the valve core 101.

[0031] According to an exemplary embodiment of the present disclosure, referring to Figure 1As shown in , the mounting rod 1 may be connected to a fixing block 13, the reset member 42 is configured as a tension spring, one end of the tension spring is connected to the operating rod 1, and the other end is connected to the fixing block 13, and the brake line 43 is connected between the fixing block 13 and the sleeve 3. In the above technical solution, a guide hole (not shown in the figure) may be provided on the fixing block 13, and the brake line 43 may be passed through the guide hole. By such a configuration, the guide hole is used to guide the brake line 43, and the tension spring may be sleeved on the brake line 43 to improve the compactness of the structure.

[0032] In order to further improve the guiding effect, a guide block can be provided on the mounting rod 1, and a through hole for guiding can be provided on the guide block, so that the brake line 43 is passed through the through hole, wherein the number of guide blocks can be one or two or more, the fixed block 13 can be arranged close to the holding end 11, the guide block can be arranged close to the mounting end 12, or the guide blocks can be arranged at intervals along the mounting rod 1, and other structures that can achieve the same purpose can also be used, and the present disclosure is not limited to this.

[0033] For easy operation, the operating rod 41 can be set to be parallel to the handle 111. With this setting, when in use, only one hand is needed to pinch the operating rod 41 and the handle 111 together to drive the operating rod 41 to move, which makes the operation more convenient.

[0034] In order to further improve the stability during use, a slide groove (not shown in the figure) extending along the length direction of the mounting rod 1 can be provided on either the sleeve 3 or the mounting rod 1, and a slide bar (not shown in the figure) can be provided on the other. Through the sliding cooperation between the slide bar and the slide groove, the sleeve 3 can be prevented from rotating relative to the mounting rod 1, thereby improving the stability of the sleeve 3 during movement, while also avoiding the distortion of the brake line 43 caused by the rotation of the sleeve 3, thereby improving the reliability of use.

[0035] According to an exemplary embodiment of the present disclosure, referring to Figure 2 As shown in , an elastic member 5 may be provided between the mounting rod 1 and the sleeve 3, and the elastic force of the elastic member 5 is used to drive the sleeve 3 to move in a direction away from the mounting rod 1. Specifically, the elastic member 5 is constructed as a spring and is provided in the connecting hole 31, one end of the spring is connected to the mounting rod 1, and the other end is connected to the sleeve 3. Through the above technical solution, the number of the elastic members 5 can be multiple, and multiple positioning grooves can be evenly opened around the sleeve 3 at one end of the sleeve 3 close to the brake line 43, so that one end of the elastic member 5 is arranged in a positioning groove, and the other end is connected to the mounting rod 1, so that the sleeve 3 is subjected to a balanced elastic force, and the sleeve 3 is quickly reset.

[0036] According to an exemplary embodiment of the present disclosure, referring to Figure 3As shown in , the two clamping jaws 2 are elastic, and the two clamping jaws 2 are respectively provided with clamping members 21, and the two clamping members 21 are arranged opposite to each other. By such arrangement, the valve core 101 can be reliably clamped. In order to further improve the reliability of clamping, the clamping member 21 can be constructed into a circular arc sheet shape, which can better fit the outer contour of the valve core 101.

[0037] In the present disclosure, the clamping member 21 can be detachably connected to the clamping jaw 2. Through such an arrangement, the clamping member 21 can be replaced when it is worn, and the fixing requirements of valve cores 101 with different diameters can also be met.

[0038] refer to Figures 1 to 4 As shown in , the specific implementation principle of the embodiment of the present disclosure is: hold the handle 111 with your hand, extend the mounting end 12 of the mounting rod 1 through the opening 102 into the interior of the airbag expansion tank 10, until the clamping claw 2 reaches the valve core 101, and then, by pinching the operating rod 41 and the handle 111 to move the operating rod 41 toward the holding end 11, the operating rod 41 drives the brake line 43 to pull the sleeve 3, so that the sleeve 3 also moves toward the holding end 11, and the sleeve 3 moves toward the holding end 11, so that the hole wall of the mounting hole 32 squeezes the two clamping claws 2, so that the two clamping claws 2 are close to each other, and the valve core 101 is clamped and fixed, so that the valve core 101 can be disassembled or installed. After the valve core 101 is disassembled or installed, the operating rod 41 is released. Under the elastic force of the reset member 42, the operating rod 41 moves toward the installation end 12, releasing the brake line 43, and the sleeve 3 slides away from the holding end 11, so that the installation hole 32 reduces the squeezing of the two clamping jaws 2, thereby loosening the clamping of the valve core 101. After that, the valve core disassembly and assembly device for the airbag expansion tank can be moved out of the airbag expansion tank 10, which is easy to operate and improves the disassembly and assembly efficiency of the valve core 101.
