[0035] The bottom end of the nail body 1 is a pointed end for easy insertion into the ground, and the top end is provided with a cavity 11 and a rope passing hole 12. The cavity 11 is open on one side and communicates with the rope passing hole 12 on the other side. The rope passing hole 12 and the cavity 11 form a rope passing channel that penetrates the nail body 1. The rope passing hole 12 is used for the rope to pass into the cavity 11. The rope passing channel is used for the rope to pass through the nail body 1, thereby fastening the end of the rope to the nail body 1. The cavity 11 is used for installing the eccentric cam 2 and the torsion spring 3, and at the same time provides space for the rope to pass through.
[0036] The eccentric cam 2 includes an integral cam body and a handle 21. The cam body is rotatably installed in the nail body 1 and located in the cavity 11. The handle 21 extends out of the nail body 1 through the opening of the cavity 11, which facilitates the user to pull the handle 21 to loosen or pass the rope.
[0037] The torsion spring 3 is installed in the cavity 11 and abuts the cam body and the nail body 1 at both ends. The torsion of the torsion spring 3 pushes the cam body to close the rope passing channel, which is used to automatically clamp the rope that passes through the rope passing channel and is located between the cam body and the nail body 1. Under the action of the torsion of the torsion spring 3, the cam body always has a tendency to rotate away from the torsion spring 3, which is used to close the rope passing channel. When the rope passes through the rope passing channel, the automatic clamping of the rope in the rope passing channel can be achieved.
[0038] As shown in Figure 5 and Figure 8 , the cam body of the eccentric cam 2 can be rotatably installed in the cavity 11 through a pin shaft 4. The pin shaft 4 penetrates the nail body 1. The cam body is provided with a through hole. The pin shaft 4 penetrates the through holes of the nail body 1 and the cam body. The cam body is rotatably installed on the pin shaft 4. When the cam body is installed on the nail body 1 through the pin shaft 4, the torsion spring 3 is sleeved on the pin shaft 4.
[0039] In the self-locking tent nail of the present embodiment, the cavity 11, the rope passing hole 12, the rope passing channel of the nail body 1 and the eccentric cam 2 can be at least in the following two specific implementation manners:
[0040] Implementation manner
[0041] As shown in Figure 3 , Figure 4 and Figure 5 , the top right side of the nail body 1 is provided with a protrusion 13. The cavity 11 is arranged at the joint of the nail body 1 and the protrusion 13. The opening of the cavity 11 is located on the lower side. The rope passing hole 12 is arranged in the protrusion 13 in the vertical direction. The bottom end of the rope passing hole 12 communicates with the cavity 11, and the top end of the rope passing hole 12 is located on the top surface of the protrusion 13. The rope passing channel penetrates the protrusion 13 and is used for the rope fastening the tent to pass through. As shown in Figure 5As shown, the eccentric cam 2 is rotatably mounted in the cavity 11 by the pin shaft 4; the handle 21 of the eccentric cam 2 extends out of the lower side opening of the cavity 11 to the outside of the nail body 1 for the user to operate the eccentric cam 2; the torsion spring 3 is sleeved on the pin shaft 4, the left end abuts against the inner wall of the nail body 1, and the right end is inserted into the groove of the cam body and abuts against the cam body; the right end and the left end of the torsion spring 3 move away from each other due to the torsion force of the torsion spring 3; since the left end of the torsion spring 3 cannot move, the handle 21 of the eccentric cam 2 always has a tendency to rotate away from the right end of the nail body 1; when the rope passes through the rope passing channel, the torsion spring 3 drives the cam body to automatically clamp the rope. When the handle 21 is rotated clockwise, the rope passing channel is formed between the cam body and the right side inner wall of the cavity 11, and at this time, the rope can pass through or be loosened; when the handle 21 is loosened, the eccentric cam 2 rotates counterclockwise under the action of the torsion spring 3, so that the eccentric cam 2 rotates towards the right side, and the outer edge of the eccentric cam 2 extrudes the rope or abuts against the inner wall of the cavity 11.
[0042] As shown in Figure 1 , the nail body 1 is provided with a mark indicating the direction of the rope passing on the outer surface of the side away from the protrusion 13; the mark can be an arrow 5 pointing downward, which prompts the user to install the rope from the top rope passing hole 12 according to the direction of the arrow 5 when setting up the tent, and then tighten the rope according to the direction of the arrow 5 to achieve fastening.
[0043] Embodiment
[0044] As shown in Figure 6 , Figure 7 and Figure 8 , which is different from the first embodiment, in this embodiment, the rope passing channel is arranged through the nail body 1 in the horizontal direction; the rope passing hole 12 is located on the left side of the nail body 1; the cavity 11 is located on the right side of the nail body 1, and the rope passing hole 12 on the left side of the nail body 1 communicates with the cavity 11 on the right side to form a rope passing channel. The eccentric cam 2 is mounted on the lower side of the cavity 11 by the pin shaft 4, and the torsion spring 3 is sleeved on the pin shaft; the upper end of the torsion spring 3 is inserted into the groove of the cam body, and the lower end of the torsion spring 3 abuts against the bottom wall of the cavity 11 of the nail body 1; the torsion force of the torsion spring 3 makes the upper end and the lower end of the torsion spring 3 move away from each other; since the lower end of the torsion spring 3 is limited by the nail body 1 and cannot rotate, the upper end of the torsion spring 3 always pushes the cam body to have a tendency to rotate counterclockwise, so that the upper edge of the cam body abuts against the top wall of the cavity 11 or the rope passing through the cavity 11, and the automatic clamping of the rope is achieved when the rope passes through the upper edge of the cam body and the top wall of the cavity 11.
[0045] On the basis of the above two embodiments, in order to improve the fastening effect of the rope, as shown in Figure 5 and Figure 8As shown, the cam body of the eccentric cam 2 is provided with a plurality of teeth 22 for preventing the rope from loosening at the side edge of the rope channel. The teeth 22 can be in a tapered structure, and a row of teeth 22 or two rows of teeth 22 can be provided on the outer edge surface of the cam body. When two rows of teeth 22 are provided, the two rows of teeth 22 can be staggered, further improving the locking effect on the rope.
[0046] As shown in Figure 5 and Figure 8 , the rope channel is provided with an arc surface 6 at the opening end of the cavity 11, and in the direction from the rope hole 12 to the opening end of the cavity 11, the rope channel gradually extends away from the cam body, that is, the end of the rope channel is inclined to the outside of the nail body 1. The outwardly inclined arc surface 6 facilitates the turning of the rope, and at the same time facilitates the application of tension to the rope. The smooth arc surface 6 can also reduce the friction of the rope, which is beneficial to prolong the service life of the rope.
[0047] As shown in Figure 1 and Figure 7 , the nail body 1 is provided with a rib plate 14 on the side away from the handle 21; the center of the rib plate 14 is provided with a circular hole 15; the circular hole 15 not only facilitates the fastening of the end of the rope, but also allows a hook or other tool to be inserted into the circular hole 15, and the nail body 1 can be pulled out of the ground by pulling the hook, facilitating the force.
[0048] As shown in Figure 1 and Figure 6 , the top end of the nail body 1 is also provided with an integral cylindrical head or square cylindrical head, which facilitates the application of force to the nail body 1 by a hammer or other tool, allowing the nail body 1 to be quickly inserted into the ground.
[0049] As shown in Figure 3 and Figure 5 , the nail body 1 is provided with a limiting ledge 16 on the lower side of the handle 21 for limiting the depth of the nail body 1 inserted into the ground; and the operating space of the eccentric cam 2 is formed between the protrusion 13 and the limiting ledge 16. The limiting ledge 16 and the nail body 1 are connected by a circular arc transition, and the outer end of the limiting ledge 16 has a bulging end 17. The nail body 1, the protrusion 13, the rib plate 14, the cylindrical head, and the limiting ledge 16 can be an integral molding structure.
[0050] In the process of using the self-locking tent peg, first, the user inserts the peg body 1 into the ground through the pointed end to fix the self-locking tent peg on the ground, and the limiting crosspiece 16 can prevent the peg from being inserted too far to ensure that the handle 21 of the eccentric cam 2 can be normally operated; then, the user rotates the eccentric cam 2 clockwise to open the rope passing channel by pulling the handle 21, passes the rope into the cavity 11 through the rope passing hole 12, and then pulls the rope head, at this time, since the direction of the rope pulling force is the same as the opening direction of the eccentric cam 2, the rope passing channel is in an open state by the opening force of the eccentric cam 2 while the rope is pulled, and the rope can be smoothly pulled; after the rope is pulled tight, there is a reverse pulling force under the action of the tent, at this time, the eccentric cam 2 is pressed by the torsional spring 3, the friction between the teeth 22 at the edge of the eccentric cam 2 and the rope is generated, the reverse pulling force of the rope is the same as the closing direction of the eccentric cam 2, and the eccentric cam 2 can tightly clamp the rope, and the greater the reverse pulling force of the rope is, the tighter the rope is clamped, so that the one-way check effect is realized, and the length of the rope can be adjusted without knotting or using other auxiliary equipment.
[0051] When the tent needs to be disassembled, the user only needs to press the handle 21 in the clockwise direction to rotate the eccentric cam 2, so that the rope is separated from the extrusion of the eccentric cam 2, the rope can be freely pulled, the purpose of loosening the tent rope is achieved, and finally the self-locking tent peg is pulled out of the ground by hooking the round hole 15 on one side of the peg body 1.
[0052] The self-locking tent peg is provided with the eccentric cam 2 which is rotatably installed in the cavity 11 of the peg body 1 through a pin shaft, and the torsional spring 3 is further sleeved on the pin shaft, and the two ends of the torsional spring 3 abut against the eccentric cam 2 and the peg body 1, so that the eccentric cam 2 always has a tendency to rotate towards the side of the rope passing channel under the action of the torsional force of the torsional spring 3, so that when the rope passes through the rope passing channel, the rope is automatically clamped between the eccentric cam 2 and the inner wall of the cavity 11 of the peg body 1 under the driving of the torsional spring 3, therefore, the self-locking tent peg has a simple and practical structure, not only retains the function of the traditional tent peg, but also increases the function of automatically fastening the rope, greatly simplifies the tent building process, and improves the building efficiency.
[0053] Meanwhile, since the self-locking tent peg adopts a self-locking design, the fixing of the tent rope is more stable, and the problem that the tent is unstable due to loose knots is effectively prevented.
[0054] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model belong to the scope of the utility model claims and equivalent technologies, the utility model also intends to include these modifications and variations.
