DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3, an automatic bearing bolt pressing device comprises a fixed shell 1, a fixed block 2 is fixedly connected to the side wall of the fixed shell 1, a fixed block 2 is arranged on each fixed block 2 away from the side of the fixed shell 1, a fixed groove 4 is opened on each fixed block 2 and the fixed block 2 3, a fixed shaft 5 is fixedly connected between the front and rear inner walls of each fixed groove 4, a fixed rod 6 is arranged between each group of corresponding fixed grooves 4, and the two ends of the fixed rod 6 are respectively rotatably sleeved on the outer side of the corresponding fixed shaft 5, an alarm 9 is fixedly arranged on one side wall of the fixed shell 1, and an alarm structure is arranged on the inner side of the fixed shell 1, the fixed shell 1 is sleeved on the outer side of the bolt, the fixed block 2 3 is moved outward to fix it, the fixed block 2 3 and the fixed rod 6 cooperate to fix the fixed block 2 3, so that the fixed shell 1 is also fixed, so that the bolts in the fixed shell 1 are also fixed and compressed, and at the same time, when the bolts are loose, the alarm structure can make the alarm 9 sound an alarm, prompting the staff to deal with it in time;

[0019] The alarm structure includes a pressing plate 10 slidably connected to the inner wall of the fixed shell 1, and a sliding block 11 is fixedly connected to the side wall of each pressing plate 10. A sliding groove 12 corresponding to each sliding block 11 is opened on the inner wall of the fixed shell 1, and a connecting spring 13 is fixedly connected to the bottom end of each sliding block 11. The end of each connecting spring 13 away from the sliding block 11 is respectively fixedly connected to the lower inner wall of the corresponding sliding groove 12, and a control button is fixedly connected to the upper inner wall of each sliding groove 12, and the control button corresponds to the alarm 9. After the fixed shell 1 is sleeved on the outside of the bolt, the pressing plate 10 presses on the top of the bolt. When the bolt is loose, as the automatic bearing rotates, the bolt will vibrate, so that the pressing plate 10 moves upward to trigger the control button. After the control button is triggered, the alarm 9 will sound an alarm;

[0020] The bottom end of each pressing plate 10 is slidably connected with a connecting clamping plate 14, and the top end of each connecting clamping plate 14 is fixedly connected with a sliding block 16. The bottom end of each pressing plate 10 is provided with a fixed shaft 5 corresponding to the sliding block 16, and the side wall of each sliding groove 15 is fixedly connected with an adjusting spring 17. One end of each adjusting spring 17 away from the sliding block 16 is respectively fixedly connected to the inner wall of the corresponding sliding groove 15. When the fixed housing 1 is sleeved on the outer side of the bolt with a smaller diameter, the elastic force of the adjusting spring 17 makes the connecting clamping plate 14 fix and clamp its side wall, so that the device can be used for bolts of different sizes;

[0021] Each adjusting spring 17 is fixedly connected with a damper, and each adjusting spring 17 is fixedly connected to the inner wall of the corresponding sliding groove 15 through the damper. The damper and the adjusting spring 17 cooperate to achieve a shock-absorbing effect and improve the clamping effect of the connecting clamp 14 on the bolt.

[0022] One end of each fixing block 2 3 away from the fixed shell 1 is fixedly connected to a mounting plate 7, and each mounting plate 7 is fixedly provided with a mounting bolt 8, and the mounting plate 7 and the fixing block 2 3 are fixed by the mounting bolt 8; a soft protective layer is provided on the inner wall of the fixed shell 1, which plays the effect of protecting the fixed shell 1 itself and the bolts.

[0023] In the utility model, when the device is in use, the fixed shell 1 is sleeved on the outside of the bolt. At this time, the pressing plate 10 is pressed on the top of the bolt, and the elastic force of the spring 17 is adjusted to make the connecting clamp 14 fix and clamp its side wall, so that the device can be used for bolts of different sizes, and then the fixing block 23 is moved outward to fix it. The fixing block 23 and the fixing rod 6 cooperate to fix the fixing block 23, thereby fixing the fixed shell 1, thereby fixing the bolt in the fixed shell 1 and tightening it. When the bolt is loose, as the automatic bearing rotates, the bolt will vibrate, thereby moving the pressing plate 10. If the movement of the pressing plate 10 is large, the control button will be triggered. After the control button is triggered, the alarm 9 will sound an alarm, prompting the staff to deal with it in time.
