[0029] The utility model is described in detail below with examples and drawings.
[0030] The utility model embodiment provides a self-locking ground anchor, as shown in the structure of Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the self-locking ground anchor includes intermediate pole body 1, anchor hook 2, tight rope structure 3 and nut 4, wherein:
[0031] Intermediate pole body 1 is slender pole, and the cross-sectional shape can be rectangle, square, circle, oval, long circle, polygon and the like, and the intermediate pole body 1 extends along the vertical direction, and the bottom end is fixedly connected with anchor hook 2, and the top end is threadedly connected with nut 4, and is installed with tight rope structure 3 through nut 4;Tight rope structure 3 can be rotatably installed on intermediate pole body 1 by 360 °, so that the angle of tight rope structure 3 can be adjusted at will after the self-locking ground anchor is installed, thereby facilitating the adjustment and fastening of the rope.
[0032] Anchor hook 2 is the bow-shaped structure bending towards one side of intermediate pole body 1, and both ends are provided with arrowhead tips 21 symmetrically distributed with intermediate pole body 1 as the center;After anchor hook 2 is inserted into the gap of wood floor and rotated by 90 °, the width of the rotated anchor hook 2 is greater than the width of the wood floor gap, and the both ends of the arrowhead tips 21 abut against the bottom surface of the wood floor, at this time, anchor hook 2 can be firmly hooked on the bottom surface of the wood floor.
[0033] As shown in Figure 1 , tight rope structure 3 is provided with rope hole 31 and fastening cam 32;Fastening cam 32 can realize automatic clamping of the rope passing through rope hole 31 by rotating.Tight rope structure 3 also has tight rope block 33, rotating shaft 34 and torsional spring (not shown in the figure);One end of tight rope block 33 is provided with mounting hole penetrating along the height direction thereof, and the limiting of tight rope block 33 on intermediate pole body 1 can be realized by arranging limiting structure on intermediate pole body 1 or tight rope block 33;Intermediate pole body 1 passes through the mounting hole, realizes the limiting of tight rope structure 3 on intermediate pole body 1, and connects tight rope structure 3 and anchor hook 2 together through intermediate pole body 1.
[0034] The rope passing hole 31 is arranged through the thickness direction of the tight rope block 33, and is used for passing the rope for setting up the tent; the tight rope block 33 is provided with an open cavity in communication with the rope passing hole 31, the rope passing hole 31 is arranged through the thickness of the tight rope block 33 and is located at the central position of the tight rope block 33; one end of the open cavity is in communication with the rope passing hole 31, the open cavity is used for mounting the fastening cam 32, and the rope passing through is clamped by the fastening cam 32; the fastening cam 32 is rotatably mounted in the open cavity through the rotating shaft 34, the rotating shaft 34 is fixedly mounted on the tight rope block 33 and passes through the open cavity, and the fastening cam 32 is rotatably mounted in the open cavity through the rotating shaft 34. The open cavity is provided with openings on two peripheral sides of the tight rope block 33 and on one side surface of the tight rope block 33, so that most of the outer peripheral side of the fastening cam 32 is exposed outside the tight rope block 33, and the upper part is also exposed outside the tight rope block 33 through the opening on one side of the tight rope block 33.
[0035] The torsional spring is mounted on the rotating shaft 34, and the two ends abut against the rotating shaft 34 and the fastening cam 32, and the torsional force of the torsional spring is used as Figure 3 the driving force for counterclockwise rotation of the fastening cam 32, so that the fastening cam 32 always has a tendency to rotate to the side of the rope passing hole 31, thereby clamping the rope between the fastening cam 32 and the inner side wall of the open cavity on the upper side of the fastening cam 32, so that the fastening cam 32 cooperates with the inner side wall of the opposite tight rope block 33 to press the rope therebetween, realizing self-locking, so that the fastening cam 32 is always in a clamped state under the action of the torsional spring; when the fastening cam 32 is rotated in the clockwise direction, Figure 3 the fastening cam 32 rotates in the clockwise direction around the rotating shaft 34, the distance between the fastening cam 32 and the inner side wall of the tight rope block 33 gradually increases, thereby increasing the gap between the fastening cam 32 and the tight rope block 33, and the rope clamped between the fastening cam 32 and the tight rope block 33 is loosened.
[0036] As Figure 3 shown, the upper surface of the fastening cam 32 is an arc surface and is provided with a plurality of teeth, and an anti-slip structure can be formed through the plurality of teeth, thereby increasing the contact area between the rope and the fastening cam 32, thereby increasing the friction force and improving the reliability of the rope fastening. The fastening cam 32 is provided with a handle 35 located outside the tight rope block 33, and the handle 35 is convenient for pressing the fastening cam 32, thereby facilitating operation.
[0037] The nut 4 at the top end of the intermediate rod body 1 is a lifting ring nut 4, and the lifting ring on the lifting ring nut 4 can be manually rotated during disassembly and assembly, thereby facilitating disassembly and assembly. Meanwhile, the lifting ring can also be used for hanging, thereby facilitating storage of the entire self-locking anchor. In addition, the lifting ring on the lifting ring nut 4 can also be used for rope passing to bind the end of the rope.
[0038] The intermediate rod body 1 and the anchor hook 2 can be an integrally formed structure; one side surface of the anchor hook 2 and one side surface of the intermediate rod body 1 form a plane, and the other side surface of the anchor hook 2 and the other side surface of the intermediate rod body 1 form a plane, for being inserted into a gap of a wooden floor.
[0039] The self-locking ground anchor has simple and practical structure, solves the function of adding a tent pulling point on the wooden floor, and increases the function of automatically fastening the rope, greatly simplifies the tent building process, and improves the building efficiency.
[0040] The use method of the self-locking ground anchor is as follows: the user inserts the anchor hook 2 and the intermediate rod body 1 of the self-locking ground anchor into the gap of the wooden floor, then rotates 90 degrees clockwise or counterclockwise, the width of the anchor hook 2 after rotation is greater than the width of the gap of the wooden floor, at this time, the self-locking ground anchor is firmly hooked on the bottom surface of the wooden floor, then one end of the rope at the four corners of the tent is inserted through the rope inserting hole 31 and pulled towards the tent. At this time, since the pulling direction of the rope is the same as the opening direction of the fastening cam 32, the rope will automatically slide above the fastening cam 32. When the pulling force of the rope disappears, the direction of the rope when it is retracted is the same as the closing direction of the fastening cam 32, and the fastening cam 32 will clamp the rope under the action of the torsional spring, thereby realizing the check effect, and the rope at the four corners of the tent can be tightened without knotting or other equipment.
[0041] When the tent rope needs to be disassembled or adjusted, the user only needs to pull the rope to press the fastening cam 32 downward, so that the fastening cam 32 rotates clockwise, then pulls the rope to the side of the fastening cam 32, so that the rope is separated from the fastening cam 32, and the rope is loosened, and the anchor hook 2 is rotated 90 degrees in the opposite direction, so that the anchor hook 2 is taken out of the gap of the wooden floor.
[0042] In summary, the above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
