DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model.

[0019] Please refer to Figure 1 - Figure 6 As shown in the figure, a kind of hot end support of automobile exhaust system convenient to disassemble, including exhaust equipment 1, fixed mechanism is provided at the top of exhaust equipment 1, fixed mechanism includes connecting column 2, moving groove 3 is opened in the bottom of connecting column 2, screw rod 4 is rotatably connected in moving groove 3, one end of connecting column 2 is provided with hexagonal column 5, the output shaft of hexagonal column 5 is fixedly connected with one end of screw rod 4 and passes through connecting column 2, the other end of connecting column 2 is provided with protection mechanism, moving block 6 is screw-connected on the outside of both ends of screw rod 4, clamping column 7 is fixedly connected to the bottom of moving block 6, clamping groove 8 is opened in the outside of exhaust equipment 1, and clamping column 7 is in the inside of clamping groove 8;When needing to fix exhaust equipment 1, by rotating hexagonal column 5 to drive screw rod 4 to rotate, so that the moving block 6 and clamping block of both ends of screw rod 4 move towards exhaust equipment 1, so that clamping block enters the clamping groove 8 in the outside of exhaust equipment 1, i.e. exhaust equipment 1 can be fixed, limiting column 9 is fixedly connected to the outside of the middle of screw rod 4, the thread opened in both ends of screw rod 4 is opposite, the size of moving block 6 is compatible with moving groove 3, screw rod 4 rotates and makes moving block 6 have the trend of rotating with screw rod 4, when the size of moving block 6 is compatible with moving groove 3, the trend of rotating with moving block 6 of screw rod 4 is hindered by moving groove 3, so by the characteristics of screw thread connection of moving block 6 and screw rod 4, screw rod 4 rotates and makes moving block 6 move on screw rod 4, because the thread opened in both ends of screw rod 4 is opposite, the moving block 6 of both ends of screw rod 4 rotates screw rod 4 drives clamping column 7 to move towards each other, limiting column 9 can limit the position of moving block 6, so as to prevent the collision of two groups of moving blocks 6.

[0020] The protection mechanism comprises a protection column 10, one end of which is fixedly connected with one end of the connecting column 2 and the screw rod 4, a plurality of blocking grooves 11 are formed on the outer side of the protection column 10, a hollow column 13 is sleeved on the outer side of the protection column 10, a plurality of blocking columns 14 are fixedly connected in the hollow column 13, the blocking column 14 is in the blocking groove 11, when the blocking column 14 in the hollow column 13 is inserted into the blocking groove 11 on the outer side of the protection column 10, the hollow column 13 cannot rotate the protection column 10, and the screw rod 4 is also locked and cannot rotate, which solves the problem that the automobile will inevitably vibrate during driving, and the vibration may cause the hexagonal column 5 to rotate, so that the two clamping blocks of the fixed exhaust device 1 cannot fasten the exhaust device 1, thereby causing the exhaust device 1 to fall off. The installation groove 15 is arranged on the both sides of the protection column 10, the installation groove 15 is formed at one end of the connecting column 2, the telescopic rod 16 is fixedly connected in the installation groove 15, the two square blocks 17 are fixedly connected on the outer side of the hollow column 13, the square blocks 17 are fixedly connected with the telescopic rod 16, the spring 18 is sleeved on the outer side of the telescopic rod 16, and the both ends of the spring 18 are fixedly connected with the square blocks 17 and the telescopic rod 16. When the spring 18 is not subjected to external force, the spring 18 pulls the square blocks 17 and the hollow column 13 to tightly adhere to one end of the protection column 10, at this time, when the blocking column 14 in the hollow column 13 is inserted into the blocking groove 11, the hollow column 13 cannot rotate, so the protection column 10 cannot rotate, because the protection column 10 is fixedly connected with the screw rod 4, so the screw rod 4 also cannot rotate. If it is needed to control the rotation of the hexagonal column 5 to drive the rotation of the screw rod 4, the hollow column 13 is pulled outward at this time, and the blocking groove 11 is separated from the blocking column 14, so that the fixing of the protection column 10 can be released, at this time, the spring 18 is stretched, and the pulling force of the spring 18 can pull the hollow column 13 to tightly adhere to the side of the installation column. Because the number of the blocking grooves 11 formed on the outer side of the protection column 10 is much larger than that of the blocking columns 14 in the hollow column 13, only the hexagonal column 5 needs to be slightly adjusted to make the blocking column 14 enter the blocking groove 11. The connecting plate 19 is fixedly connected at both ends of the connecting column 2, a plurality of screws 20 are penetrated through the connecting plate 19, the connecting column 2 is installed below the base of the vehicle, the corresponding mounting holes are formed below the base of the vehicle in advance, the mounting holes are aligned with the connecting plate 19, the screws 20 are screwed through the connecting plate 19 and the mounting holes, and the fixing of the connecting column 2 is completed. The heat insulation plate 21 is arranged in the clamping column 7 and is fixedly connected with the clamping column 7. The clamping column 7 needs to tightly adhere to the exhaust device 1, and a large amount of heat is generated when the exhaust device 1 works.

[0021] The utility model discloses a connecting column 2 and the installation of vehicle need to set up corresponding mounting hole in advance below vehicle base, and the mounting hole is aligned with connecting plate 19, and the fixed fastening of connecting column 2 can be completed with screw 20 penetrating connecting plate 19 and mounting hole threaded connection, when needing to fix exhaust equipment 1, pull out hollow column 13 and hinder groove 11 to separate from hindering column 14 at this time, so that the fixed protection column 10 can be released, at this time, spring 18 is stretched, then through the rotation hexagonal column 5 drive screw rod 4 rotation, thereby make the both ends of screw rod 4 moving block 6 and the card block to exhaust equipment 1 move, thereby let the card block enter the card slot 8 of exhaust equipment 1 outside, can fix exhaust equipment 1, at this time, fine adjustment hexagonal column 5 makes the hindering column 14 in the inside of hollow column 13 and the outside of protection column 10 hinder groove 11 alignment, loosen hollow column 13, and the pulling force of spring 18 can pull hollow column 13 to the side of fixed column hindering column 14 enters hinder groove 11 and locks up protection column 10.
