[0002] Ground spikes, also known as ground anchors or ground nails, are commonly used to secure tents, awnings, parasols, and livestock leashes.
[0003] Existing ground spikes are generally long and narrow, and are driven directly into the ground during use. On softer ground, the squeezing force between the long and narrow ground spikes and the soil is small, resulting in low friction between the ground spikes and the soil, which ultimately leads to insufficient grip and affects the firmness of the ground spikes. Utility Model Content
[0004] The purpose of the present invention is to provide a parent-child ground nail. When the parent-child ground nail is used, the child nail is inserted into the soil in an inclined state. At the same time, the lower part of the child nail passes through the through hole of the mother nail. When the mother nail is pulled upward, the soil above the child nail exerts a large resistance on the child nail, thereby improving the grip of the parent-child ground nail in the soil, so that the parent-child ground nail can provide firm positioning support even on relatively soft ground.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a mother-and-child ground nail, comprising a mother nail and a child nail, the child nail being detachably arranged on the mother nail, and the angle between the mother nail and the child nail being an acute angle, and the upper part of the mother nail being a rope binding part.

[0008] Furthermore, a bending plate inclined toward the guide hole is provided on the upper portion of the female nail, and a binding opening is provided on both sides of the bending portion of the bending plate, and the outer side of the binding opening is connected to the outside world.
[0009] Furthermore, the binding opening is larger on the outside and smaller on the inside.
[0010] Furthermore, the mother nail is in a flat strip structure or the cross section of the mother nail is in a C-shaped structure.
[0011] Furthermore, the sub-nail has a round rod-shaped structure.
[0012] Furthermore, the parent-child ground nail also includes an anti-drop component for preventing the child nail from being pulled out of the guide hole.
[0013] Furthermore, the anti-slip component is a padlock, and a first through hole distributed along its radial direction is provided on the guide hole, and a second through hole cooperating with the first through hole is provided at the upper lower position of the sub-nail, and the lock beam of the padlock can pass through the first through hole and the second through hole.

[0025] The following will be combined with specific embodiments and attached Figure 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some preferred embodiments of the present invention, not all embodiments. Those skilled in the art may make similar modifications without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] The utility model provides a parent-child ground nail (such as Figure 1 The screw 2 is fixed on the ground with its upper end fixed on the bottom surface, and the lower end fixed on the ground with its lower end fixed on the bottom surface is fixed on the ground with its lower end fixed on the bottom surface. Figure 2As shown, in this specific embodiment, the angle α between the mother nail 1 and the child nail 2, theoretically, the closer α is to 90 degrees, the greater the resistance the child nail 2 will encounter when being pulled upwards, but this will result in a larger lateral span of the utility model. Therefore, considering the span of the utility model and the grip effect of the child nail 2, the value of α is preferably set to 60 degrees. The upper part of the mother nail 1 is a rope binding part. In actual application, after the mother nail 1 and the child nail 2 are driven into the ground, the draw ropes of sunshade components such as tents and awnings are tied to the rope binding part, thereby realizing the positioning and fixing function of the utility model.
[0027] On the basis of the above embodiment, a specific implementation method of the detachable connection between the mother nail 1 and the child nail 2 is as follows: a support frame 3 is provided on the lower side of the upper part of the mother nail 1. In order to facilitate the fixed connection between the support frame 3 and the mother nail 1 and to facilitate the vertical support placement of the mother nail 1 so that the support frame 3 and the mother nail 1 remain vertical to each other, a guide hole 31 (such as Figure 3 As shown in the figure, a pair of through holes 11 are provided at the upper bottom of the mother nail 1, and the bottom of the sub-nail 2 can be inserted into the through holes 11 after passing through the guide hole 31. Since the sub-nail 2 is tilted relative to the mother nail 1, it can be directly deduced that the guide hole 31 is also tilted relative to the mother nail 1, and the sub-nail 2 can slide freely in the guide hole 2 and the through hole 11. Therefore, after the mother nail 1 is driven into the ground, the guiding effect of the guide hole 31 on the sub-nail 2 is utilized. By continuously hammering the upper part of the sub-nail 2, the lower part of the sub-nail 2 can still be smoothly penetrated into the through hole 11 in the soil. When the lower part of the sub-nail 2 is sleeved in the through hole 11 and the upper part is sleeved in the guide hole 31, the connection between the mother nail 1 and the sub-nail 2 is realized, and the sub-nail 2 is tilted relative to the mother nail 1. When the parent nail 1 is pulled vertically upward, the factor nail 2 is inserted obliquely into the soil, resulting in a larger upward pulling resistance for the parent nail 1, and the lower part of the factor nail 2 is inserted into the through hole 11, which indirectly causes the parent nail 1 to be subjected to a larger upward pulling resistance, thereby improving the grip of the parent nail 1 and the child nail 2. When the utility model needs to be removed from the ground, the child nail 2 is first pulled out from the ground obliquely. When the child nail 2 is pulled obliquely, the child nail 2 is pulled along the axial direction of the child nail 2. At this time, the friction resistance encountered by the child nail 2 is small, and then it is easy to pull it out of the ground. After the child nail 2 is pulled out, the parent nail 1 is pulled vertically upward again. At this time, the parent nail 1 loses the blocking effect of the child nail 2, and its pulling resistance is greatly reduced, which then facilitates its pulling out. After the parent nail 1 is pulled out of the ground, the removal of the parent and child ground nails on the ground is realized.
[0028] Furthermore, in order to facilitate the processing and manufacturing of the guide hole 31 on the support frame 3, a guide sleeve 312 (such as Figure 4 As shown), the inner hole of the guide sleeve 312 is the guide hole 31 described above.
[0029] On the basis of the above embodiment, the specific implementation method of the rope binding part on the upper part of the female nail 1 is as follows: a bending plate 12 inclined toward the guide hole 2 is provided on the upper part of the female nail 1, and a binding opening 13 is provided on both sides of the bending part of the bending plate 12. The outer side of the binding opening 13 is connected to the outside world. In actual application, the rope is wrapped in the binding opening 13, which is convenient for realizing the movement limitation of the rope. Furthermore, in actual use, the bending plate 12 is back to the direction in which the pull rope pulls the object, so that the bending angle of the bending plate 12 can be used to effectively prevent the pull rope from detaching from the upper part of the female nail 1, thereby improving the binding stability of the pull rope and the female nail 1. Furthermore, in order to facilitate the smooth binding of the rope into the binding opening 13, the binding opening 13 is made large on the outside and small on the inside. The outside of the binding opening 13 is large, which facilitates the rope to slide into the binding opening 13, and the inside of the binding opening 13 is small, which facilitates the centralized fixed binding of the rope.
[0030] In actual application, after the present invention is driven into the ground, in order to improve the anti-theft effect of the present invention, the parent-child ground nail further includes an anti-dropout component for preventing the child nail 2 from being pulled out of the guide hole 31. After the child nail 2 is fixed on the guide hole 31 by the anti-dropout component, the child nail 2 cannot be pulled out smoothly. The child nail 2 cannot be pulled out smoothly from the ground, and the parent nail 1 cannot be pulled out smoothly from the ground, thereby improving the anti-theft function of the present invention to a certain extent. In this specific embodiment, the anti-dropout component is a The padlock is provided with a first through hole 311 distributed along its radial direction on the guide hole 31, and a second through hole cooperating with the first through hole is provided at the upper lower position of the sub-nail 2. The lock beam of the padlock can pass through the first through hole and the second through hole. In actual application, when the first through hole 311 and the second through hole are completely penetrated, the lock beam is inserted into the first through hole 311 and the second through hole, and then the padlock is locked, so that the movement limit of the sub-nail 2 relative to the guide hole 31 can be realized, thereby realizing anti-theft.
[0031] On the basis of the above embodiment, in the process of inserting the sub-nail 2 into the guide hole 31 and the through hole 11, in order to facilitate the smooth penetration of the first through hole 311 and the second through hole, a guide rail distributed along its axial direction is provided on the outer wall of the sub-nail 2, and a guide groove matching the guide rail is provided on the inner wall of the guide hole 31. The guide rail can slide up and down in the guide groove, and the guide rail is sleeved in the guide groove. At the same time, the guide groove is used to limit the guide rail, thereby realizing the positioning of the first through hole 311 and the second through hole in the length direction of the sub-nail 2. A limiting ring is provided on the sub-nail 2 above the second through hole. When the After the limiting ring rests against the upper part of the guide hole 31, the locking beam can pass through the first through hole 311 and the second through hole, that is, after the sub-nail 2 is inserted into the guide hole 31, as the sub-nail 2 continues to move, the limiting ring gradually approaches the upper part of the guide hole 31. As the sub-nail 2 continues to move, when the limiting ring fits with the upper part of the guide hole 31, the first through hole 311 and the second through hole are exactly coaxially distributed, thereby successfully achieving precise penetration of the first through hole 311 and the second through hole. After the first through hole 311 and the second through hole are penetrated, it is convenient for the locking beam to be inserted into the first through hole 311 and the second through hole, thereby successfully realizing the anti-theft function using the padlock.
[0032] In order to facilitate the striking and rotating of the sub-nail 2 , a hexagonal block is provided on the upper portion of the sub-nail 2 .
[0033] In actual application, when the soil on the ground is relatively compact, the mother nail 1 or the child nail 2 can be used alone as a fixed positioning tool on the ground. When the soil on the ground is relatively soft, the combination of the mother nail 1 and the child nail 2 can be used as a fixed positioning tool on the ground, thereby improving the flexibility of the present invention.
[0034] In practical applications, in order to facilitate the smooth driving of the female nail 1 into the ground, the lower part of the female nail 1 is made into a cone shape. Furthermore, in order to improve the ability of the female nail 1 to resist oblique tension in the soil, the female nail 1 is made into a flat strip structure or the cross section of the female nail 1 is a C-shaped structure. When the female nail 1 is a flat structure, when the female nail 1 with a flat structure is subjected to the normal oblique tension of its wider side, the wide side has a large contact area with the soil, resulting in a large resistance of the soil to it, that is, its ability to resist oblique tension is better. However, when it is subjected to the normal oblique tension of its narrower side, The narrow surface of the mother nail 1 has a small contact area with the soil, resulting in a small resistance of the soil to it, that is, its anti-oblique tension ability is poor; when the cross-section of the mother nail 1 is a C-shaped structure, the contact area of the mother nail 1 with the soil in all directions is large, and when the mother nail 1 is subjected to an oblique tension in any direction, the mother nail 1 has a strong anti-oblique tension ability; further, in order to facilitate the smooth oblique insertion of the sub-nail 2 into the guide hole 31, the soil and the through hole 11, the sub-nail 2 is made into a round rod structure. In order to improve the structural strength of the present invention, the mother nail 1 and the sub-nail 2 can be made of steel materials.
[0035] In the present invention, "up", "down", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.
[0036] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
[0037] The above description, in conjunction with the accompanying drawings, details the preferred embodiments and examples of the present invention. However, the present invention is not limited to the above embodiments and examples. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
