When dealing with drilling holes with different opening depths, the use length of the anchor rod is not convenient to adjust, and the top of the anchor rod cannot be directly placed close to the deepest part of the drill hole, which brings inconvenience to the subsequent grouting operation and reduces the supporting effect of the anchor rod. When the anchor rod is partially damaged, the anchor rod needs to be replaced as a whole, which is not convenient for the recycling of the anchor rod and causes waste of resources.

[0004] Therefore, we propose a snap-fit ​​assembled recyclable anchor rod to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a snap-assembled recyclable anchor rod to solve the problem that when dealing with drilling holes with different opening depths, the top of the anchor rod cannot be directly placed close to the deepest part of the drill hole, thereby reducing the support effect of the anchor rod, and when the anchor rod is partially damaged, the anchor rod needs to be replaced as a whole, resulting in a waste of resources.

[0007] Preferably, an outer side of the lower portion of the anchor rod 1 is provided with an external thread, the threaded sleeve is adaptably connected to the external thread, and the splicing portion is cylindrical.

[0008] By adopting the above technical solution, a splicing assembly is provided to facilitate the splicing of anchor rod one and anchor rod two. Similarly, other anchor rods two can be spliced ​​on anchor rod two to adapt to different lengths. This is convenient for adapting to drilling holes of different depths, improves the support effect of subsequent anchor rods, and will not cause the splicing to loosen during the subsequent rotation process, thereby improving the splicing effect of the anchor rods.

[0009] Preferably, a through hole is provided inside the splicing portion, the through hole is connected to the inside of the first anchor rod, the through hole is connected to the inside of the second anchor rod, and an adaption structure is also provided on the top of the second anchor rod.

[0011] Preferably, the sliding blocks are symmetrically arranged, there are no less than two sliding blocks, the number of the first sliding grooves matches the number of sliding blocks, the sliding blocks are slidably connected to the second sliding grooves, and there are two fixed rods symmetrically arranged.

[0012] By adopting the above technical solution, when splicing is required, the top of anchor rod one is brought close to the bottom of anchor rod two, anchor rod two is rotated, the position of the sliding block is kept corresponding to the first sliding groove, and then the splicing part is inserted into the splicing groove, and the blocking block is pressed into the inside of the sliding block to facilitate subsequent splicing operations.

[0013] Preferably, one end of the clamping spring is fixedly connected to the sliding block, the other end of the clamping spring is fixedly connected to the blocking block, the clamping spring is slidably connected to the fixing rod, and the step groove is symmetrically opened up and down.

[0014] By adopting the above technical solution, when the blocking block is pressed, the blocking block will squeeze the clamping spring, and the clamping spring will shrink under the force. At this time, the sliding block slides to the bottom of the first sliding groove, and then the anchor rod 2 is rotated clockwise. The anchor rod 2 drives the splicing part and the sliding block to rotate, so that the sliding block moves to the second sliding groove, and the blocking block pops out and is stuck in the inside of the slot, thereby completing the splicing.

[0015] Preferably, auxiliary grooves are symmetrically opened in the sliding block, a guide block is fixedly connected to the side of the blocking block close to the fixed rod, a guide rod is fixedly connected to the auxiliary groove, and the guide block is slidably connected to the guide rod.

[0018] By adopting the above technical solution, when the anchor rod is inserted into the drill hole, the outer tube body is inserted first, and the outer tube body drives the contact plate thereon to move. When the contact plate is close to the drill hole, it will be squeezed by the drill hole, causing the contact plate to shrink toward the center. At the same time, the inclined setting of one end of the contact plate facilitates the close contact between the contact plate and the inner wall of the drill hole, thereby improving the installation effect of the outer tube body and making it more convenient for subsequent anchor rod support.

[0019] Preferably, four telescopic rods are symmetrically arranged, the lower part of the contact plate is inclined and inclined toward the side close to the outer tube body, one end of the auxiliary spring is fixedly connected to the contact plate, and the other end of the auxiliary spring is fixedly connected to the outer tube body.

[0020] By adopting the above technical solution, the symmetrically arranged contact plates are distributed around the outer side of the outer tube body, so as to better abut against the inner wall of the borehole and facilitate subsequent support.

[0021] Compared with the prior art, the invention has the following beneficial effects: a splicing assembly is provided to facilitate the splicing of anchor rod one and anchor rod two, and similarly, other anchor rods two can be spliced ​​on anchor rod two to adapt to different lengths, which is convenient for adapting to drilling holes of different depths and improves the supporting effect of subsequent anchor rods; 1. A splicing assembly is provided, which includes an anchor rod 1, an anchor rod 2, a splicing part, a sliding block, a blocking block, a first slide groove, a second slide groove, a clamping groove, a fixing rod, a clamping spring and a limit block. When splicing is required, the top of the anchor rod 1 is brought close to the bottom of the anchor rod 2, the anchor rod 2 is rotated, the position of the sliding block is kept corresponding to the first slide groove, and then the splicing part is inserted into the splicing groove, the blocking block is pressed into the inside of the sliding block, the blocking block squeezes the clamping spring, the clamping spring is forced to shrink, and the sliding block slides to the bottom of the first slide groove. When the bottom of the splicing part fits with the bottom of the splicing groove, the position of the sliding block is at the same horizontal position as the second slide groove, and the anchor rod is rotated clockwise. The second anchor rod drives the splicing part and the sliding block to rotate, so that the sliding block moves to the second sliding groove. At this time, the elastic force of the clamping spring drives the blocking block to pop outward, so that the blocking block is stuck in the inside of the clamping groove, thereby completing the splicing of the first anchor rod and the second anchor rod. Similarly, other second anchor rods can be spliced ​​on the second anchor rod to adapt to different lengths, which is convenient for adapting to drilling holes of different depths, improves the support effect of subsequent anchor rods, and solves the problem that when dealing with drilling holes of different opening depths, the top of the anchor rod cannot be directly placed close to the deepest part of the drilling hole, which reduces the support effect of the anchor rod. When the anchor rod is partially damaged, the anchor rod needs to be replaced as a whole, resulting in a waste of resources. 2. When the clamping spring drives the blocking block to pop out, and then the blocking block is stuck in the inside of the clamping groove, the blocking block slides on the outside of the fixing rod, so that the limiting block slides in the inside of the step groove. Since the diameter of the limiting block is larger than the diameter of the fixing rod, the limiting block will not fall out of the inside of the step groove, thereby blocking the blocking block, so that the blocking block will not fall out from the outside of the sliding block, thereby realizing a limit position of the anchor rod by the blocking block, and the sliding block is stuck in the inside of the second sliding groove to limit the anchor rod, thereby improving the splicing strength, and will not cause the splicing looseness in the subsequent rotation process, thereby improving the splicing effect of the anchor rod. At the same time, the blocking block drives the guide block to slide in the auxiliary groove to assist the sliding of the blocking block, and also plays a role in further limiting and blocking the blocking block. The splicing method is convenient for replacing the damaged parts when the anchor rod is partially damaged, and there is no need to replace the anchor rod as a whole, thereby reducing resource waste. 3. A telescopic rod and a contact plate are provided. When the anchor rod is inserted into the drill hole, the outer tube body is inserted first, and the outer tube body drives the contact plate thereon to move. When the contact plate is close to the drill hole, it will be squeezed by the drill hole, causing the contact plate to shrink toward the center, and the contact plate compresses the telescopic rod and the auxiliary spring on the outside of the telescopic rod. At the same time, the inclined setting of one end of the contact plate makes it easier for the contact plate to fit closely against the inner wall of the drill hole, thereby improving the installation effect of the outer tube body and making it more convenient for subsequent anchor rod support.

The through hole is connected with the interior of anchor rod 1, and the through hole is connected with the interior of anchor rod 2. An adapting structure is also provided on the top of anchor rod 2.

[0026] A groove 16 is provided inside the sliding block 10, and the blocking block 11 is slidably connected to the groove 16. A fixing rod 17 is fixedly connected inside the groove 16. A step groove 19 is provided inside the blocking block 11.

[0027] The sliding blocks 10 are symmetrically arranged, there are no less than two sliding blocks 10, the number of the first sliding grooves 13 matches the number of the sliding blocks 10, the sliding blocks 10 are slidably connected to the second sliding grooves 14, and there are two fixing rods 17 symmetrically arranged.

[0030] Embodiment 1: Figure 2-8 As shown, when splicing is required, the top of anchor rod 1 is brought close to the bottom of anchor rod 2, and anchor rod 2 is rotated to keep the position of sliding block 10 corresponding to the first slide groove 13, and then the splicing part 9 is inserted into the splicing groove 12, and the blocking block 11 is pressed into the inside of the sliding block 10. The blocking block 11 squeezes the clamping spring 18, and the clamping spring 18 is forced to shrink. At this time, the sliding block 10 slides to the bottom of the first slide groove 13. When the bottom of the splicing part 9 is in contact with the bottom of the splicing groove 12, the position of the sliding block 10 is at the same horizontal position as the second slide groove 14. The anchor rod 2 is rotated clockwise, and the anchor rod 2 drives the splicing part 9 and the sliding block 10 to rotate, so that the sliding block 10 moves to the second slide groove 14.

[0031] At this time, the elastic force of the clamping spring 18 drives the blocking block 11 to pop outward, so that the blocking block 11 is stuck in the inside of the clamping groove 15, thereby completing the splicing of anchor rod 1 and anchor rod 2. Similarly, other anchor rods 2 can continue to be spliced ​​on anchor rod 2 to adapt to different lengths, which is convenient for adapting to drilling holes of different depths, improves the support effect of subsequent anchor rods, and solves the problem that when dealing with drilling holes of different opening depths, the top of the anchor rod cannot be directly placed close to the deepest part of the drilling hole, which reduces the support effect of the anchor rod. When the anchor rod is partially damaged, the anchor rod needs to be replaced as a whole, resulting in a waste of resources.

[0032] At the same time, the blocking block 11 drives the guide block 22 to slide in the auxiliary groove 21 to assist the sliding of the blocking block 11, and also plays a role in further limiting the position of the blocking block 11.

[0033] The outer side of the outer tube body 6 is fixedly connected with a telescopic rod 23 , one end of the telescopic portion of the telescopic rod 23 is fixedly connected with a contact plate 24 , and the outer side of the telescopic rod 23 is sleeved with an auxiliary spring.

[0034] Four telescopic rods 23 are symmetrically arranged, the lower part of the contact plate 24 is inclined and inclined toward the side close to the outer tube body 6 , one end of the auxiliary spring is fixedly connected to the contact plate 24 , and the other end of the auxiliary spring is fixedly connected to the outer tube body 6 .

[0035] Embodiment 2: Figure 1 and Fig. 9 As shown, when the anchor rod is inserted into the drill hole, the outer tube body 6 is inserted first, and the outer tube body 6 drives the contact plate 24 thereon to move. When the contact plate 24 is close to the drill hole, it will be squeezed by the drill hole, causing the contact plate 24 to shrink toward the center, and the contact plate 24 compresses the telescopic rod 23 and the auxiliary spring on the outside of the telescopic rod 23. At the same time, the inclined setting of one end of the contact plate 24 makes it easier for the contact plate 24 to fit closely with the inner wall of the drill hole, thereby improving the installation effect of the outer tube body 6 and making it more convenient for subsequent anchor rod support and use.

[0036] Working principle: When using the device, first, Figure 1-9 As shown, when the anchor rod is inserted into the borehole, the outer tube body 6 is first inserted, and the outer tube body 6 drives the contact plate 24 thereon to move. When the contact plate 24 is close to the borehole, it will be squeezed by the borehole, causing the contact plate 24 to shrink toward the center, and the contact plate 24 compresses the telescopic rod 23 and the auxiliary spring outside the telescopic rod 23. At the same time, the inclined setting of one end of the contact plate 24 facilitates the contact plate 24 to be closely attached to the inner wall of the borehole, thereby improving the installation effect of the outer tube body 6, thereby making it more convenient for the subsequent support and use of the anchor rod. Next, the anchor rod is positioned by cooperating with the anchor plate 3 and the fixing nut 4. After adjustment, the anchor rod is grouted inside the anchor rod by a grouting pump so that concrete is injected into the borehole. After the injection is completed, the sealing plug 5 can be installed to seal the anchor rod. After the grouting is completed, the fixing nut 4 can be loosened to remove the anchor plate 3. At this time, the anchor rod 2 is rotated, and the anchor rod 2 drives the anchor rod 1 to rotate, so that the threaded portion of the anchor rod 1 is disengaged from the threaded sleeve 8, thereby facilitating the removal and recovery of the anchor rod.

[0037] When splicing is required, bring the top of anchor rod 1 close to the bottom of anchor rod 2, rotate anchor rod 2, keep the position of sliding block 10 corresponding to the first slide groove 13, and then insert the splicing part 9 into the splicing groove 12, press the blocking block 11 into the inside of the sliding block 10, the blocking block 11 squeezes the clamping spring 18, and the clamping spring 18 is forced to shrink. At this time, the sliding block 10 slides to the bottom of the first slide groove 13.

[0038] When the bottom of the splicing part 9 is in contact with the bottom of the splicing groove 12, the position of the sliding block 10 is at the same horizontal position as the second sliding groove 14. The anchor rod 2 is rotated clockwise, and the anchor rod 2 drives the splicing part 9 and the sliding block 10 to rotate, so that the sliding block 10 moves to the second sliding groove 14. At this time, the elastic force of the clamping spring 18 drives the blocking block 11 to pop outward, so that the blocking block 11 is stuck in the inside of the clamping groove 15, thereby completing the splicing of the anchor rod 1 and the anchor rod 2.

[0039] When the clamping spring 18 drives the blocking block 11 to pop out, and then the blocking block 11 is stuck in the inside of the slot 15, the blocking block 11 slides on the outside of the fixing rod 17, so that the limit block 20 slides in the inside of the step groove 19. Since the diameter of the limit block 20 is larger than the diameter of the fixing rod 17, the limit block 20 will not fall out from the inside of the step groove 19, thereby blocking the blocking block 11, so that the blocking block 11 will not fall out from the outside of the sliding block 10, thereby realizing the blocking block 11 limiting the anchor rod 1, and the sliding block 10 is stuck in the second slide groove 14 to limit the anchor rod 1, thereby improving the splicing strength, and will not cause the splicing to loosen during the subsequent rotation process, thereby improving the splicing effect of the anchor rod.

[0040] At the same time, the blocking block 11 drives the guide block 22 to slide inside the auxiliary groove 21, which is used to assist the sliding of the blocking block 11 and also serves to further limit the blocking block 11. Similarly, other anchor rods 2 can be spliced ​​on the anchor rod 2 to adapt to different lengths, which is convenient for adapting to drilling holes of different depths and improves the support effect of subsequent anchor rods.
