Technical Field
[0001] The utility model relates to the field of resin bolts with internal anchoring agents, in particular to resin bolts with internal anchoring agents. Background Art
[0002] In the mine roadway support system, resin bolts have the characteristics of short setting time and fast force application. When connecting the bolt and the anchor head, usually only need to insert the anchor head into the inside of the bolt. However, this will cause the bolt to be easily loosened from the anchor head when inserted into the ground, so it is necessary to fix the two of them.
[0003] Common resin bolts with internal anchoring agents only include the function of injecting grease, which can inject the anchoring agent into the ground, but lack the function of quick connection and alignment of the anchor head, and cannot ensure that the anchor head can be quickly connected and fixed with the bolt. It is easy to occur that the bolt is easily loosened from the anchor head when inserted into the ground, affecting the quality of grease injection.
[0004] Therefore, aiming at the lack of the function of quick connection and alignment of the anchor head in the above-mentioned resin bolts with internal anchoring agents, a resin bolt with internal anchoring agent can be designed. By inserting the head connecting piece into the inside of the anchoring connecting cylinder to connect the two, when the head connecting piece is inserted into the anchoring connecting cylinder, the limiting block will be squeezed. The limiting block drives the elastic positioning rod to move towards the inner cavity of the head connecting piece. When the limiting block moves to the limiting groove, the limiting block is pushed by the elastic positioning rod to be stuck into the inside of the limiting groove, so as to ensure that the anchor head can be quickly connected and fixed with the anchoring connecting cylinder. Summary of the Utility Model
[0005] In order to overcome the problems of common resin bolts with internal anchoring agents, which lack the function of quick connection and alignment of the anchor head, cannot ensure that the anchor head can be quickly connected and fixed with the bolt, and are easy to occur that the bolt is easily loosened from the anchor head when inserted into the ground, affecting the quality of grease injection.
[0006] The technical solution of the utility model is: a resin bolt with internal anchoring agent, including an anchor head; also including a head connecting piece, a positioning groove, and an elastic positioning rod. A head connecting piece is arranged on the right side of the anchor head. Two positioning grooves are symmetrically arranged on the upper and lower sides of the periphery of the head connecting piece, and an elastic positioning rod is arranged at the left end inside the positioning groove.
[0007] Preferably, the head connector is inserted into the internal part of the anchoring connection cylinder to connect the two. When the head connector is inserted into the anchoring connection cylinder, the limit block will be squeezed. The limit block drives the elastic positioning rod to move into the inner cavity of the head connector. When the limit block moves to the limit groove, the limit block is pushed by the elastic positioning rod to be clamped into the internal part of the limit groove, so as to ensure that the anchor head can be quickly butt - jointed and fixed with the anchoring connection cylinder, thus solving the problem that the common internal - setting anchoring agent resin bolt only has the function of injecting grease, can inject the anchoring agent into the ground, but lacks the function of quick - connection and alignment of the anchor head, and cannot ensure that the anchor head can be quickly butt - jointed and fixed with the anchoring connection cylinder, and it is easy to have looseness between the anchoring connection cylinder inserted into the ground and the anchor head, affecting the grease - injection quality.
[0008] Preferably, an anchoring connection cylinder is arranged at the position corresponding to the head connector on the right side of the anchor head, and the head connector is inserted into the internal part of the anchoring connection cylinder.
[0009] Preferably, two limit grooves are symmetrically opened at the upper and lower ends on the left side of the whole body of the anchoring connection cylinder corresponding to the positions of the elastic positioning rods. Limit blocks are arranged on one side of the two elastic positioning rods close to the limit grooves, and the limit blocks are clamped into the internal parts of the limit grooves.
[0010] Preferably, a fixing ring is arranged on the right side of the head connector, and four reamers are arranged at equal intervals on the right side of the fixing ring.
[0011] Preferably, a sealing washer is sleeved on the whole body of the fixing ring, and the sealing washer is made of plastic material.
[0012] Preferably, two grease - outlet grooves are symmetrically opened at the upper and lower ends of the whole body of the anchor head, and two nail heads are symmetrically arranged on the front and back sides of the whole body of the anchor head.
[0013] Preferably, two slurry - outlet grooves are symmetrically opened at the front and back sides on the right side of the whole body of the anchoring connection cylinder. A propulsion connector is arranged on the right side of the anchoring connection cylinder, and a resin - roll anchoring agent is arranged inside the anchoring connection cylinder.
[0014] The beneficial effects of the utility model:
[0015] 1. The head connector and the anchoring connection cylinder are connected by inserting the head connector into the interior of the anchoring connection cylinder. While the head connector is being inserted into the anchoring connection cylinder, the limit block will be squeezed. The limit block drives the elastic positioning rod to move towards the inner cavity of the head connector. When the limit block moves to the limit groove, the limit block is snapped into the interior of the limit groove by the thrust of the elastic positioning rod, thus ensuring that the anchor head can be quickly docked and fixed with the anchoring connection cylinder. This solves the problem of the common internal anchoring agent resin bolt, which only has the function of injecting grease, can inject the anchoring agent into the ground, but lacks the function of quick connection and alignment of the anchor head, and cannot ensure that the anchor head can be quickly docked and fixed with the anchoring connection cylinder. It is easy to loosen between the anchoring connection cylinder inserted into the ground and the anchor head, affecting the grease injection quality. Brief Description of the Drawings

Two positioning grooves 3 are symmetrically opened on the upper and lower sides of the periphery of the head connecting piece 2. An elastic positioning rod 4 is arranged at the left end inside the positioning groove 3. By inserting the head connecting piece 2 into the internal part of the anchoring connection cylinder 6 to connect the two, when the head connecting piece 2 is inserted into the anchoring connection cylinder 6, the limit block 5 will be squeezed. The limit block 5 drives the elastic positioning rod 4 to move into the inner cavity of the head connecting piece 2. When the limit block 5 moves to the limit groove 7, due to the thrust of the elastic positioning rod 4, the limit block 5 is clamped into the internal part of the limit groove 7, so as to ensure that the anchor head 1 can be quickly butt-joined and fixed with the anchoring connection cylinder 6, so as to solve the problem that the common internal anchoring agent resin bolt only has the function of injecting grease and can inject the anchoring agent into the ground, but lacks the function of quick connection and alignment of the anchor head 1, and cannot ensure that the anchor head 1 can be quickly butt-joined and fixed with the anchoring connection cylinder 6, and it is easy to loosen between the anchoring connection cylinder 6 and the anchor head 1 when the anchoring connection cylinder 6 is inserted into the ground, affecting the grease injection quality.
[0022] Please refer to Figures 2-4 , in this embodiment, a sealing washer 10 is sleeved on the periphery of the fixing ring 8. The sealing washer 10 is made of plastic material. Two grease outlet grooves 11 are symmetrically opened on the upper and lower ends of the periphery of the anchor head 1. Two nail heads 12 are symmetrically arranged on the front and back sides of the periphery of the anchor head 1. Two slurry outlet grooves 13 are symmetrically opened on the front and back sides of the right side of the periphery of the anchoring connection cylinder 6. A propulsion connector 14 is arranged on the right side of the anchoring connection cylinder 6. A resin roll anchoring agent 15 is arranged inside the anchoring connection cylinder 6. After the anchor head 1 is fixed, the anchoring connection cylinder 6 is inserted into the ground, and then an external propulsion rod is screwed into the internal part of the anchoring connection cylinder 6. The resin roll anchoring agent 15 is pushed out from the grease outlet grooves 11 of the anchor head 1 through the external propulsion rod, and the sealing washer 10 can prevent the resin roll anchoring agent 15 from flowing back to the external propulsion rod. Wait for one minute for the resin to quickly solidify, and then inject cement slurry into the internal part of the anchoring connection cylinder 6 through the external propulsion rod. The cement slurry is injected into the ground through the slurry outlet grooves 13 of the anchoring connection cylinder 6, and the operations of grease injection and grouting are completed.
[0023] Please refer to Figures 1-4, in this embodiment, an anchoring connection cylinder 6 is provided at the position corresponding to the head connecting member 2 on the right side of the anchor head 1. The head connecting member 2 is inserted into the interior of the anchoring connection cylinder 6. Two limiting grooves 7 are symmetrically opened at the upper and lower ends on the left side of the whole body of the anchoring connection cylinder 6 corresponding to the positions of the elastic positioning rods 4.

The limiting blocks 5 drive the elastic positioning rods 4 to move into the inner cavity of the head connecting member 2. When the limiting blocks 5 move to the positions of the limiting grooves 7, the limiting blocks 5 are snapped into the interiors of the limiting grooves 7 by the thrust of the elastic positioning rods 4, so as to ensure that the anchor head 1 can be quickly butt-joined and fixed with the anchoring connection cylinder 6, realizing the function of quick connection and alignment of the anchor head 1, and preventing the problem that when the anchoring connection cylinder 6 is inserted into the ground, it is easy to loosen from the anchor head 1, affecting the grouting quality.
[0024] During operation, by inserting the head connecting member 2 into the interior of the anchoring connection cylinder 6 to connect the two, when the head connecting member 2 is inserted into the anchoring connection cylinder 6, the limiting blocks 5 will be squeezed. The limiting blocks 5 drive the elastic positioning rods 4 to move into the inner cavity of the head connecting member 2. When the limiting blocks 5 move to the positions of the limiting grooves 7, the limiting blocks 5 are snapped into the interiors of the limiting grooves 7 by the thrust of the elastic positioning rods 4, so as to ensure that the anchor head 1 can be quickly butt-joined and fixed with the anchoring connection cylinder 6. After the anchor head 1 is fixed, the anchoring connection cylinder 6 is inserted into the ground, and then an external push rod is screwed into the interior of the anchoring connection cylinder 6. The resin cartridge anchor 15 is pushed out from the grease outlet groove 11 of the anchor head 1 through the external push rod, and the sealing washer 10 can prevent the resin cartridge anchor 15 from flowing back to the external push rod. Wait for one minute for the resin to solidify quickly, and then inject cement slurry into the interior of the anchoring connection cylinder 6 through the external push rod. The cement slurry is injected into the ground through the slurry outlet groove 13 of the anchoring connection cylinder 6, realizing the function of quick connection and alignment of the anchor head 1.
[0025] Through the above steps, the head connector 2 is inserted into the inside of the anchoring connection cylinder 6 to connect the two. While the head connector 2 is inserted into the anchoring connection cylinder 6, the limit block 5 will be squeezed. The limit block 5 drives the elastic positioning rod 4 to move towards the inner cavity of the head connector 2. When the limit block 5 moves to the limit groove 7, the limit block 5 is pushed by the elastic positioning rod 4 to be snapped into the inside of the limit groove 7, so as to ensure that the anchor head 1 can be quickly butt-jointed and fixed with the anchoring connection cylinder 6, so as to solve the problem of the common internal anchoring agent resin bolt, which only has the function of injecting grease and can inject the anchoring agent into the ground, but lacks the function of quick connection and alignment of the anchor head 1, and cannot ensure that the anchor head 1 can be quickly butt-jointed and fixed with the anchoring connection cylinder 6, and it is easy to loosen between the anchoring connection cylinder 6 and the anchor head 1 when the anchoring connection cylinder 6 is inserted into the ground, affecting the grease injection quality.
