[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figure 1 And Figure 2 As shown in [drawings not specified], an embodiment provided by the present invention: A mining construction tie rod device includes two telescopic rods 4. A connecting cylinder 5 is fixedly connected to the front side of the telescopic rod 4. A pulling block 10 is arranged on the front side of the connecting cylinder 5. A connecting rod 12 is fixedly connected to the rear side of the pulling block 10. An insert block 13 is fixedly connected to one end of the connecting rod 12. A first spring 11 is arranged outside the connecting rod 12. Uniformly distributed jacks 6 are opened on the front side inside the telescopic rod 4. The insert block 13 is slidably connected inside the jack 6. A connecting component is fixedly connected to the corresponding end of the telescopic rod 4. One end of the first spring 11 is fixedly connected to the front side inner wall of the connecting cylinder 5, and the other end of the first spring 11 is fixedly connected to the rear side inner wall of the connecting cylinder 5;

[0030] The connecting component includes a threaded rod 7. The threaded rod 7 is fixedly connected to the corresponding end of the telescopic rod 4. The outside of the threaded rod 7 is threadedly connected with a mounting cylinder 8.

[0031] By pulling the pulling block 10, the connecting rod 12 drives the insert block 13 to move, separate from the jack 6 and slide into the connecting cylinder 5 while squeezing the first spring 11, so as to perform telescopic adjustment on the telescopic rod 4; by screwing the threaded rod 7 into the inside of the mounting cylinder 8, the tie rod can be installed and spliced.

[0032] Refer to Figure 1 And Figure 3, one end of the telescopic rod 4 is fixedly connected with a mounting block 9. An external connector 2 is arranged outside the mounting block 9. Both the front and rear sides inside the connector 2 are provided with sliding grooves 16. Both the front and rear sides inside the connector 2 are provided with telescopic members 15. The telescopic members 15 are fixedly connected to one inner wall of the sliding grooves 16. One end of the telescopic member 15 is fixedly connected with a clamping block 18. A second spring 17 is arranged outside the telescopic member 15. One end of the second spring 17 is fixedly connected to one inner wall of the sliding groove 16, and the other end of the second spring 17 is fixedly connected to one side of the clamping block 18. Slots 14 are provided on both the front and rear sides of the mounting block 9. The clamping block 18 is slidably connected inside the slot 14. A bolt 1 is threadedly connected inside the connector 2. The bolt 1 is threadedly connected through the connector 2 into the mounting block 9. A nut 3 is threadedly connected to the outside of one end of the bolt 1. The clamping block 18 is slidably connected inside the sliding groove 16.

[0033] By inserting the mounting block 9 into the connector 2 to squeeze the clamping block 18, so as to squeeze the telescopic member 15 and the second spring 17. When the mounting block 9 is completely inserted into the connector 2, the position of the slot 14 is aligned with the clamping block 18, and the clamping block 18 loses the extrusion force. Due to the resilience of the second spring 17, the telescopic member 15 expands and contracts to drive the clamping block 18 to move and insert into the slot 14. The bolt 1 passes through the connector 2 and the mounting block 9 to fix them, and the nut 3 is screwed to the outside of one side of the bolt 1 to further stably install.

[0034] Working principle: When the device needs to be used, it is connected to an external device through the connector 2. The mounting block 9 is inserted into the connector 2. The mounting block 9 squeezes the clamping block 18, and at the same time squeezes the telescopic member 15 and the second spring 17. When the mounting block 9 is completely inserted into the connector 2, the clamping block 18 loses the extrusion force. Due to the resilience of the second spring 17, the telescopic member 15 expands and contracts, driving the clamping block 18 to move and insert into the slot 14 to fix it. The bolt 1 passes through the connector 2 and the mounting block 9 and is threadedly connected thereto, and the nut 3 is screwed to the outside of one side of the bolt 1, realizing the connection, installation and reinforcement of the pull rod and the external device, making its installation and fixation stable. By pulling the pull block 10, it drives the plug 13 to move through the connecting rod 12, so that the plug 13 moves into the connecting cylinder 5 and squeezes the first spring 11 to generate a resilience force, and then the telescopic rod 4 can be telescoped, realizing the telescopic adjustment of the length of the pull rod and improving the utilization rate of the pull rod.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
