[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See the instruction manual Figure 1To the instruction manual Figure 5 The utility model provides a head bolt mounting support, including a support body 1, a head bolt mounting hole 2 is provided in the middle of the top of the support body 1, and a thrust ball bearing 3 is provided in the inner cavity of the head bolt mounting hole 2. Through the setting of the thrust ball bearing 3, the impact load transmitted through the head bolt mounting hole 2 can be borne, thereby reducing the influence of the impact load on the support body 1.

[0021] The bottom end of the support body 1 is evenly provided with fixing holes 4, and mounting bolts 6 are arranged in the fixing holes 4, and the support body 1 and the device 13 can be fixed together by the mounting bolts 6. Tension arms 5 are fixed at both ends of one side of the support body 1, and another fixing hole 4 is evenly arranged on the tension arm 5, and the tension arm 5 and the device 13 can be connected by the mounting bolts 6.

[0022] The mounting bolt 6 comprises a nut portion 7, a screw portion 8 connected to the nut portion 7 and a connecting screw tube 9 threadedly connected to the screw portion 8, both ends of the connecting screw tube 9 are provided with limiting grooves 10, one end of the nut portion 7 away from the screw portion 8 is fixed with a limiting plate 11 adapted to the limiting groove 10, and the inner and outer walls of the connecting screw tube 9 are both provided with threads.

[0023] From the above description of the mounting bolt 6, it can be seen that during the screwing and use of the mounting bolt 6, the screw portion 8 and the connecting screw tube 9 are in a meshing state, and the screw portion 8 is connected to the device 13 through the connecting screw tube 9. When the screw portion 8 is broken, the user inserts the limiting plate 11 into the limiting groove 10 and rotates the nut portion 7, so that the connecting screw tube 9 and the device 13 can be quickly separated, thereby facilitating the removal of the broken screw portion 8.

[0024] The limiting piece 11 is a conical structure, and the thickness of one end of the limiting piece 11 away from the nut portion 7 is smaller than the thickness of the other end thereof, thereby increasing the speed at which the user inserts the limiting piece 11 into the limiting groove 10 .

[0025] The above-mentioned tension arm 5 is located between another fixing hole 4 and the head bolt mounting hole 2. Through the setting of the tension arm 5, the tension arm can share a part of the impact load, change the force mode of the mounting support, reduce the impact of the impact force on the mounting bolt 6, reduce the probability of the mounting bolt 6 breaking, and improve the reliability and life of the mounting support during use.

[0026] A buffer pad is fixed to the inner wall of the fixing hole 4. The buffer pad can be made of rubber. Through the setting of the buffer pad, the resilience of the buffer pad can reduce the impact of the impact load on the mounting bolt 6, thereby improving the stability of the mounting bolt 6 when in use.

[0027] From the above description, it can be seen that the present application is an improvement on the plate-like mounting bracket in the prior art, by adding two tension arms, changing the force-bearing mode of the mounting bracket, solving the problem of bolt breakage, and improving the life and reliability of the mechanism; and improving the mounting bolts so that broken mounting bolts can be quickly removed.

[0028] In summary: when the head bolt mounting support is used, the mounting bolt 6 is used to connect the support body 1 and the tension arm 5 with the device 13, and the head bolt 12 is located in the head bolt mounting hole 2. The schematic diagram of the application is shown in the attached manual. Figure 5 When the mounting support is in use, the head bolt 12 bears the impact force transmitted from the device 13, and transmits it to the tension arm 5 and the mounting bolt 6 through the support body 1. The tension arm 5 shares a part of the impact load, changes the force mode of the mounting support, reduces the probability of the mounting bolt 6 breaking, and improves the reliability and life of the mounting support when in use; and when the mounting bolt 6 breaks, the user inserts the limiting plate 11 into the limiting groove 10, and screws the nut part 7. The nut part 7 can drive the connecting screw 9 to rotate through the limiting plate 11 and the limiting groove 10, and the connecting screw 9 drives the broken screw part 8 to rotate. The screw part 8 broken in the device 13 can be quickly taken out, which is convenient for replacing the mounting bolt 6.
