[0028] 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.

[0029] Reference Figure 1 , Attachment Figure 2 and attached Figure 3 The utility model provides an embodiment: an anti-dropping bolt with a card slot, comprising a mounting cap 1, a screw rod 2 is fixedly connected to the bottom end of the mounting cap 1, a threaded rod 404 is rotatably connected inside the mounting cap 1, a mounting groove 403 is provided inside the screw rod 2, a threaded sleeve 406 is threadedly connected to the outside of the threaded sleeve 406, two connecting rods 405 are rotatably connected to the outside of the threaded sleeve 406, two card slots 402 are provided on the outer surface of the screw rod 2, a card block 401 is slidably connected to the inside of the card slot 402, and a twisting component is installed on the outer surface of the mounting cap 1.

[0030] Specifically, when the bolt has entered the interior of the object to be fixed, the rotating disk 5 is rotated to rotate the threaded rod 404, and further the threaded sleeve 406 and the connecting rod 405 move downward. Under the traction force of the connecting rod 405, the block 401 contacts the inner wall of the object to be fixed, so that it is firmly fixed, thereby effectively preventing the bolt from loosening due to vibration and working load, thereby extending the service life of the bolt and the entire device, and improving the durability and reliability of the device.

[0031] Please see attached Figure 1 and attached Figure 4 The twisting assembly includes two receiving grooves 601, both of which are provided on the outer wall of the mounting cap 1, the interior of the receiving groove 601 is rotatably connected to a rotating shaft 603, and the exterior of the rotating shaft 603 is fixedly connected to a square rod 602;

[0032] Specifically, by pushing the push block 7 outward, the square rod 602 is disengaged from the inside of the storage groove 601 under the rotation of the rotating shaft 603. At this time, the user can use the two square rods 602 to rotate the bolt to achieve disassembly. The overall structural design is reasonable and easy to use.

[0033] Please see attached Figure 4 The shape of the square rod 602 matches the shape of the inner wall of the storage groove 601, and the outer part of the square rod 602 is fixedly connected with a toggle block 7;

[0034] Specifically, the design of the storage groove 601 can store the square rod 602 .

[0035] Please see attached Figure 2 The bottom end of the threaded rod 404 is fixedly connected with a fixing block 8, the fixing block 8 is rotatably connected to the outer surface of the mounting groove 403, and the other end of the connecting rod 405 is rotatably connected to the outside of the clamping block 401;

[0036] Specifically, the fixing block 8 can better ensure that the threaded rod 404 can be more stable when rotating.

[0037] Please see attached Figure 1 and attached Figure 2 , the bottom end of the screw rod 2 is fixedly connected with a cone head 3;

[0038] Specifically, the cone head 3 can better penetrate into the outer surface of the object to be fixed so as to fix it.

[0039] The top end of the threaded rod 404 is fixedly connected to a rotating disk 5, and the outer surface of the rotating disk 5 is provided with anti-slip grooves;

[0040] Specifically, it is convenient for the staff to rotate the rotating disk 5 to rotate the threaded rod 404 , and the design of the anti-slip pattern can increase the friction between the fingers of the staff, making it easier to twist the rotating disk 5 .

[0041] Please see attached Figure 4 The two square rods 602 are arranged symmetrically along the middle of the mounting cap 1.

[0042] Specifically, it is convenient for the user to rotate the bolt with the help of the two square rods 602, so that the bolt can be disassembled even if the user forgets to carry tools.

[0043] Working principle: To use this product, use a tool to screw the cone head 3 and the screw rod 2 into two objects to be fixed. At this time, by rotating the rotating disk 5, the threaded rod 404 rotates, and further the threaded sleeve 406 moves downward along the outer wall of the threaded rod 404, and drives one end of the connecting rod 405 to swing. At this time, under the traction of the connecting rod 405, the clamping block 401 moves along the inner wall of the clamping groove 402 until the clamping block 401 contacts the inner wall of the object to be fixed, so that it is firmly fixed, thereby achieving the anti-falling effect of the bolt;

[0044] In addition, when the bolt needs to be disassembled, the toggle block 7 is pulled outward so that the square rod 602 is disengaged from the inside of the storage groove 601 under the rotation of the rotating shaft 603. At this time, the user can use the two square rods 602 to rotate the bolt to achieve disassembly. The overall structural design is reasonable and easy for people to use.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
