[0025] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example 1: Please refer to Figures 1-8 The utility model provides a technical solution: a quick braking device for a trailer, comprising a valve body 1 and a plurality of connecting pipes 16, wherein one end of the inner connecting pipe 16 away from the valve body 1 is fitted with the other end of the outer connecting pipe 16 close to the valve body 1, so that the connecting pipe 16 can stably transport gas, and the left and right sides of the valve body 1 are fixedly connected with a mounting block 2, and two plug blocks 4 are slidably connected inside the separated sides of the two mounting blocks 2, and the mounting block 2 plays a limiting role on the plug blocks 4, so that the plug blocks 4 can slide smoothly, and the right end of the plug block 4 is fixedly connected with a mounting block 2 3, and the mounting block 2 is fitted with the mounting block 2 3, so that the connection of the connecting pipe 16 is more stable, and the upper and lower sides of the interior of the mounting block 2 are provided with a clamping groove 5, and the interior of the clamping groove 5 is clamped with a clamping block 6, and the clamping block 6 passes through the clamping block 4, so that the connection between the mounting block 2 and the mounting block 2 3 is more stable, the inner connecting pipe 16 is fixedly connected to the interior of the mounting block 1 2, and the outer connecting pipe 16 is fixedly connected to the interior of the mounting block 2 3.
[0027] When it is necessary to separate the mounting block 1 2 and the mounting block 2 3, the clamping block 6 is pulled out from the inside of the clamping groove 5 and the inserting block 4, and then the mounting block 2 3 is pulled outward, so that the mounting block 2 3 can drive the inserting block 4 to detach from the inside of the mounting block 1 2, so that the valve body 1 can be easily inspected. Conversely, the inserting block 4 is slid into the inside of the mounting block 1 2, and when the mounting block 2 3 and the mounting block 1 2 are fitted, the clamping block 6 is passed through the inserting block 4 and engaged with the inside of the clamping groove 5, so that the mounting block 1 2 and the mounting block 2 3 can be stably installed, so that workers do not need to carry tools during maintenance, which makes the workers' operation more convenient and the maintenance efficiency higher.
[0028] The second embodiment: On the basis of the first embodiment, in order to realize the convenience of pulling the card block 6, two mounting grooves 7 are provided inside the mounting block 2, and the right side of the interior of the mounting block 2 is rotatably connected with a rotating shaft 8. The mounting block 2 plays a limiting role on the rotating shaft 8, so that the rotating shaft 8 will not deviate during rotation, and the rotating shaft 8 is movably connected to the interior of the mounting block 2 3, so that the rotating shaft 8 will not be affected during rotation. The outside of the rotating shaft 8 is fixedly connected with two pull ropes 9, and the pull rope 9 is slidably connected to the inside of the mounting groove 7. The mounting groove 7 plays a limiting role on the pull rope 9, so that the pull rope 9 will not deviate during sliding. An elastic member 10 is provided on the outside of the pull rope 9, and the end of the pull rope 9 away from the rotating shaft 8 is fixedly connected to the limiting block 11, and the limiting block 11 is slidably connected to the inside of the mounting groove 7. The mounting groove 7 plays a limiting role on the limiting block 11, so that the limiting block 11 can slide smoothly. One end of the elastic member 10 is fixedly connected to the inner wall of the mounting groove 7, and the other end of the elastic member 10 is fixedly connected to the limiting block 11.
[0029] When it is necessary to move the card block 6, the rotating shaft 8 is rotated so that the rotating shaft 8 can wrap the pull rope 9, and the pull rope 9 can pull the limit block 11 to squeeze the inside of the elastic member 10, so that the limit block 11 can pull the card block 6 into the inside of the installation groove 7, and the card block 6 can be disengaged from the inside of the plug block 4 and the card slot 5, so that the plug block 4 is no longer restricted, and the mounting block 2 3 can be removed from the mounting block 1 2. Conversely, by inserting the plug block 4 into the inside of the mounting block 2 and then loosening the rotating shaft 8, the elastic member 10 can push the limit block 11 to move outward, so that the limit block 11 can push the card block 6 to penetrate the plug block 4 and engage with the inside of the card slot 5, so that the plug block 4 can be stably installed.
[0030] Example 3: On the basis of Example 2, in order to achieve a more stable connection of the connecting tube 16, a sealing groove 17 is provided at the end of the connecting tube 16, and a plurality of placement grooves 12 are provided inside the mounting block 12. The inner wall of the placement groove 12 is fixedly connected with an elastic member 2 13, and the other end of the elastic member 2 13 is fixedly connected with a push block 18. The push block 18 is slidably connected to the inside of the placement groove 12. The placement groove 12 limits the push block 18 inside, so that the push block 18 does not deviate when sliding. The end of the push block 18 away from the elastic member 2 13 is fixedly connected with a push rod 14, and the other end of the push rod 14 is fixedly connected with a sealing ring 15. The sealing ring 15 fits with the inside of the sealing groove 17, thereby sealing the connection between the two connecting tubes 16.
[0031] When the mounting block 1 2 fits with the mounting block 2 3 , the outer connecting tube 16 is able to enter the interior of the mounting block 1 2 and fit with the inner connecting tube 16 . At this time, the outer connecting tube 16 is able to slide inside the sealing ring 15 , thereby allowing the sealing ring 15 to push the push rod 14 to move toward the direction close to the elastic member 2 13 , thereby allowing the push rod 14 to push the elastic member 2 13 through the push block 18 to extrude and deform. Then, when the elastic member 2 13 performs a reset movement, the elastic member 2 13 is able to push the push rod 14 to move toward the direction close to the connecting tube 16 through the push block 18, thereby allowing the push rod 14 to push the sealing ring 15 into the interior of the sealing groove 17, making the connection of the connecting tube 16 more stable, thereby ensuring that the braking effect will not be affected.
[0032] In actual use, by rotating the shaft 8, the shaft 8 is able to wrap the pull rope 9, and the pull rope 9 is able to pull the limit block 11 to squeeze the inside of the elastic member 10, so that the limit block 11 is able to pull the card block 6 into the inside of the installation groove 7, and the card block 6 is able to disengage from the inside of the plug block 4 and the card slot 5, so that the plug block 4 is no longer restricted, so that the mounting block 2 3 can be removed from the mounting block 1 2. Conversely, by inserting the plug block 4 into the inside of the mounting block 1 2 and then loosening the shaft 8, the elastic member 10 is able to push the limit block 11 to move outward, so that the limit block 11 is able to push the card block 6 to penetrate the plug block 4 and engage with the inside of the card slot 5, so that the plug block 4 can be stably installed, and the outer connecting pipe 16 is able to enter the inside of the mounting block 1 2 The outer connecting tube 16 is fitted with the inner connecting tube 16. At this time, the outer connecting tube 16 is able to slide inside the sealing ring 15, thereby enabling the sealing ring 15 to push the push rod 14 to move in the direction close to the elastic member 13, thereby enabling the push rod 14 to push the elastic member 13 to be squeezed and deformed through the push block 18. Then, when the elastic member 13 performs the reset movement, the elastic member 13 is able to push the push rod 14 to move in the direction close to the connecting tube 16 through the push block 18, thereby enabling the push rod 14 to push the sealing ring 15 into the interior of the sealing groove 17, thereby not only making it convenient to install and disassemble the connecting tube 16, but also making the installation stability higher, thereby enabling workers to carry no tools during maintenance, making the workers' operation more convenient, thereby improving the maintenance efficiency.
