Technical Field

[0001] The utility model belongs to the technical field of anchoring devices, in particular to a reusable anchor point. Background Art

[0002] Most anchor devices in the prior art use expansion screws to fix hanging plates, but the expansion screws cannot be pulled out after expansion, let alone reused. This one-time use method is inefficient and wastes resources in some cases, especially in situations where the anchor points need to be moved frequently, such as aerial work, mountaineering, and rescue, where the existing expansion screws are particularly inconvenient. Therefore, there is an urgent need for an anchor device that can be easily removed after use and can be reused. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the utility model proposes a reusable anchor point, including a fixing bolt, a mobile integrated component extending from one end of the fixing bolt, a load-bearing body extending from the side of the mobile integrated component away from the fixing bolt, an expansion steel sheet embedded in the mobile integrated component, a hexagonal nut sleeved on the mobile integrated component, a fixed hanging ring sleeved on the outer side of the hexagonal nut, a hanging plate fixing rubber ring is provided on the load-bearing body, and a spring is embedded between the mobile integrated component and the load-bearing body.

[0005] As an improvement, the mobile integrated component is provided with an expansion steel sheet fixing groove, the expansion steel sheet is embedded in the expansion steel sheet fixing groove, the mobile integrated component is provided with a steel ball guide groove on its circumference, two groups of steel balls slide in the steel ball guide groove, and the steel balls are slidably embedded with the hexagonal nuts.

[0006] As an improvement, a hanging plate fixing point and an expansion steel plate moving groove are provided on one side of the load-bearing body close to the moving integrated component, and the expansion steel plate is embedded and slidably in the expansion steel plate moving groove.

[0007] As an improvement, the load-bearing body is provided with an expansion steel sheet contraction point and an expansion steel sheet expansion point at a position away from the fixing point of the hanging sheet, and the diameter of the expansion steel sheet expansion point is greater than the diameter of the expansion steel sheet contraction point.

[0008] As an improvement, the expansion steel sheets are arranged in three groups in a circular array.

[0009] As an improvement, the load-bearing body is made of a high-strength alloy and can withstand use in a high-load environment.

[0010] The beneficial effects achieved by the utility model with the above structure are as follows: by pressing the bolt or twisting the hexagonal nut to make the steel ball slide on the guide rail, the expansion steel sheet is driven to slide to make the device expand and shrink in the pore, thereby fixing the anchor point and pulling out the anchor point, achieving the following technical effects:

[0011] 1. Realize the reuse of anchor points, saving resources and costs;

[0012] 2. Simple operation and easy use, suitable for use in high-altitude operations, mountaineering, rescue and other occasions where frequent movement of anchor points is required;

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4As shown, a reusable anchor point proposed by the utility model comprises a fixing bolt 1, a moving integrated component 2 is extended at one end of the fixing bolt 1, a load-bearing body 3 is extended on the side of the moving integrated component 2 away from the fixing bolt 1, the load-bearing body 3 is made of high-strength alloy and can withstand use in a high-load environment, an expansion steel sheet 4 is embedded in the moving integrated component 2, and the expansion steel sheet 4 is provided in three groups in a circular array, a hexagonal nut 5 is sleeved on the moving integrated component 2, a fixing hanging ring 6 is sleeved on the outer side of the hexagonal nut 5, a hanging sheet fixing rubber ring 7 is provided on the load-bearing body 3, and a spring 8 is embedded in the moving integrated component 2 and the load-bearing body 3.

[0022] like Figure 3 As shown, the mobile integrated component 2 is provided with an expansion steel sheet fixing groove 9, the expansion steel sheet 4 is embedded in the expansion steel sheet fixing groove 9, and the mobile integrated component 2 is provided with a steel ball guide groove 10 on its circumference. Two groups of steel balls 11 slide in the steel ball guide groove 10, and the steel balls 11 are slidably embedded with the hexagonal nuts 5.

[0023] like Figure 3 As shown, a hanging piece fixing point 12 and an expansion steel sheet moving groove 13 are provided on one side of the load-bearing body 3 close to the moving integrated component 2 , and the expansion steel sheet 4 is embedded and slidably disposed in the expansion steel sheet moving groove 13 .

[0024] like Figure 1 , 2 As shown in 3 , the load-bearing body 3 is provided with an expansion steel sheet contraction point 14 and an expansion steel sheet expansion point 15 at a position away from the hanging plate fixing point 12 , and the diameter of the expansion steel sheet expansion point 15 is greater than the diameter of the expansion steel sheet contraction point 14 .

[0025] When in use, the expansion steel sheet 44 is fixed on the expansion steel sheet fixing groove 9 of the mobile integrated component 2. At the same time, a steel ball guide groove 10 is provided on the mobile integrated component 2. A steel ball 11 is installed on the steel ball guide groove 10. When the fixing bolt 1 is pressed and the hexagonal nut 2 is turned clockwise, the hexagonal nut 2 rotates and applies force to the steel ball 11, allowing the steel ball 11 to move along the steel ball guide groove 10, forcing the mobile integrated component 2 to move in the direction close to the fixing bolt 1, thereby pulling the expansion steel sheet 4 on the expansion steel sheet 4 moving groove to slide toward the expansion steel sheet reduction point 14. Since the diameter of the expansion steel sheet reduction point 14 is smaller, the whole The diameter of the device becomes smaller, and then the whole device can be inserted into the pre-punched hole; then the hexagonal nut 2 is turned counterclockwise, and the hexagonal nut 2 rotates and applies force to the steel ball 11, so that the steel ball 11 moves along the steel ball guide groove 10, forcing the mobile integrated component 2 to move in the direction away from the fixing bolt 1, thereby pushing the expansion steel sheet 4 to slide toward the expansion point 15 of the expansion steel sheet. Since the diameter of the expansion point 15 of the expansion steel sheet is larger, the expansion steel sheet 4 is affected by the increase in diameter at the expansion point 15 of the expansion steel sheet, so that the diameter of the whole device is expanded, and the device is stuck in the hole and cannot be pulled out, forming an anchor point;

[0026] When the device needs to be removed, the hexagonal nut 2 is turned clockwise by hand or using a tool such as a wrench. The hexagonal nut 2 applies force to the steel ball 11, causing the steel ball 11 to move along the steel ball guide groove 10, pulling the expansion steel sheet 4 to slide toward the expansion steel sheet shrinkage point 14, so that the diameter of the entire device becomes smaller, and the device can be taken out of the hole, thereby realizing the reuse of the anchor point.
