Technical Field

[0001] The utility model relates to the field of anchor bolts, in particular to a universal climbing anchor bolt. Background Art

[0002] A climbing anchor is a device used for climbing and fixing. Current climbing anchors are stressed by expansion friction. After tightening the nut, the hook angle is fixed and cannot be adjusted. Therefore, its application scenarios are limited. However, a universal climbing anchor can form a key effect by cutting into the base material through the key edge. When the bolt is tightened, the universal mechanism can rotate at will. During the climbing process, the multi-directional rotation and friction of the anchor enable it to maintain contact with the surface and provide stable support.

[0003] Currently, when users climb using anchor bolts, they control themselves using ropes. When users pull the ropes, they are impacted, which causes discomfort to the users. In addition, long-term wear of the connection between the ropes and the fasteners causes wear of the ropes, thereby reducing the service life of the ropes. Therefore, a universal climbing anchor bolt is proposed to address the above problems. Utility Model Content

[0022] The following combines the attached Figures 1-5 to further elaborate on the present application in detail,

[0023] The embodiment of the present application discloses a universal climbing anchor bolt. Referring to Figure 1 , a universal climbing anchor bolt includes an anchor bolt body 1, an insertion rod 2 is inserted into the interior of the anchor bolt body 1, a universal joint 3 is hinged to the right side of the insertion rod 2, a buffer assembly 4 is arranged on the right side of the universal joint 3, and a limiting component 5 is arranged on the right side of the universal joint 3;

[0024] Referring to Figures 2-3 , the buffer assembly 4 includes an inner groove 41 opened inside the right side of the universal joint 3. A sliding block 42 is slidably connected inside the inner groove 41. A connecting rod 43 is fixedly connected to the right end of the sliding block 42. Horizontal grooves are provided at both the front and rear ends on the left side of the inner groove 41. The front and rear sides of the sliding block 42 are slidably connected inside the horizontal grooves, keeping the sliding block 42 sliding inside the inner groove 41 and not detaching from the universal joint 3. The connecting rod 43 passes through the inner groove 41 and extends to the outside of the universal joint 3. A first connecting block 44 is fixedly connected to the right end of the connecting rod 43. A fastener 45 is fixedly connected to the right side of the first connecting block 44. A fixing roller 46 is fixedly connected to one side of the surface of the fastener 45 close to the first connecting block 44. A protective sleeve 47 is fixedly connected to the middle of the surface of the fastener 45. Telescopic rods 48 are fixedly connected to both the front and rear sides of the first connecting block 44 close to one end of the universal joint 3. Rounded corners are provided at the edges of the fastener 45 so that the rope will not be damaged when it contacts the edges of the fastener 45. The ends of the telescopic rods 48 far from the first connecting block 44 are fixedly installed on the surface of the universal joint 3. The telescopic rods 48 further limit the first connecting block 44, so that the first connecting block 44 will not be pulled off the universal joint 3, further ensuring the safety when the first connecting block 44 pulls the rope.

[0025] Referring to Figures 4-5 , the limiting assembly 5 includes two columns 51 fixedly installed on both the upper and lower sides of the right end face of the universal joint 3. A pressing block 52 is fixedly installed on the surface of the column 51. A sliding rod 53 is slidably connected inside the side of the pressing block 52 far from the column 51. A first return spring 54 is fixedly installed inside the sliding rod 53. A telescopic rod 55 is slidably connected inside the pressing block 52. The pressing block 52 and the first connecting block 44 are adapted to contact each other. The sliding rod 53 and the right side of the first connecting block 44 are adapted to contact each other. A connecting rod is fixedly connected to the adjacent ends of the sliding rod 53 and the telescopic rod 55. Before the pressing block 52 contacts the first connecting block 44, at this time the sliding rod 53 will first contact the first connecting block 44. At this time, the sliding rod 53 drives the telescopic rod 55 to move away from the first connecting block 44. A second return spring 56 is fixedly installed inside the telescopic rod 55. A second connecting block 57 is fixedly blocked on the left side of the telescopic rod 55. A rotating rod 58 is rotatably connected to the left side of the pressing block 52. An abutting block 59 is provided on the side of the rotating rod 58 close to the pressing block 52. The rotating rod 58, the abutting block 59 and the left side of the first connecting block 44 are adapted to contact each other. A cross groove is provided on the side of the rotating rod 58 close to the first connecting block 44. The second connecting block 57 is slidably connected inside the cross groove. The second connecting block 57 keeps sliding inside the rotating rod 58, and when the second connecting block 57 moves, it will drive the rotating rod 58 to rotate, so that the rotating rod 58 and the abutting block 59 support on the left side of the first connecting block 44, thereby further limiting the first connecting block 44.

[0026] Working principle: The operator digs a hole in the mountain, then inserts the anchor body 1 into the hole, and then rotates the insertion rod 2 to stably insert it into the anchor body 1. Then the user can pass the rope through the fixed roller 46 and sleeve it on the protective cover 47 on the surface of the fastener 45. Then the operator can sleeve the rope on himself to climb;

[0027] During the climbing process, the operator pulls the fastener 45 and the connecting block 1 44, and the connecting block 1 44 pulls the connecting rod 43 and the sliding block 42 to move inside the inner groove 41, and the connecting block 1 44 stretches the telescopic rod 1 48, and the connecting block 1 44 moves slightly in the direction of leaving the universal joint 3, and the stretched telescopic rod 1 48 provides a buffering capacity, thereby reducing the impact force received by the user when starting to climb;

[0028] At the same time, when the connecting block 1 44 moves away from the universal joint 3, the connecting block 1 44 stretches the telescopic rod 1 48 to move to the limit position. At this time, the connecting block 1 44 presses the pressure block 52. During the movement of the connecting block 1 44, the sliding rod 53 is pushed. At this time, the sliding rod 53 stretches the reset spring 1 54 inside the pressure block 52 and moves to the right. At this time, the sliding rod 53 drives the telescopic rod 2 55 to move accordingly through the connecting rod. At this time, the telescopic rod 2 55 drives the connecting block 2 57 to move accordingly. At this time, the connecting block 2 When 57 moves, it always slides inside the inclined rotating rod 58. At this time, the rotating rod 58 is subjected to a component force toward the direction of the connecting block 44, so the connecting block 57 will pull the rotating rod 58 to rotate and abut against the left side of the connecting block 44. At the same time, the abutting block 59 also abuts against the left side of the connecting block 44. At this time, the pressing block 52 and the abutting block 59 respectively abut against the left and right sides of the connecting block 44, thereby limiting the connecting block 44, thereby ensuring that the connecting block 44 will not be separated from the universal joint 3 and thus ensuring safety.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
