Description

Technical Field

[0001] The utility model relates to an anti-dropping combined U-shaped nail, belonging to the technical field of U-shaped nails. Background Art

[0002] U-shaped nails are also called turf nails. Their general shapes can be divided into four types: square head turf nails, round head turf nails, G head turf nails, and capped turf nails. The materials include cold drawn wire, galvanized wire, galvanized steel wire, stainless steel wire, etc. Turf nails are the most widely used. Turf nails are mainly used to fix turf on golf courses, garden lawns and other places where turf is needed. They are also used to fix cover cloths, straw mats, round pipes, etc. They are easy to operate, of high quality and low price.

[0003] A Chinese patent publication (publication number: CN 202867469 U) discloses a U-shaped nail, including a nail body, a nail cap and a nail tip. The characteristics are: the nail cap is annular, the nail cap and the nail body are integrated, and the nail tip is a conical shape with four cut surfaces. The conical nail tip with four cut surfaces of the utility model can be easily and quickly nailed into the nailed object; the annular nail cap can easily pull out the U-shaped nail nailed into the object, realizing the reuse of the U-shaped nail;

[0004] However, the surface of the U-shaped nail in the above device is relatively smooth. When the U-shaped nail is inserted into the ground, if it is accidentally hit by external factors, the space where the U-shaped nail is inserted in the soil will become larger. At this time, the U-shaped nail will be loose when it is in the soil. When it is affected by external force again, the U-shaped nail will easily fall off from the soil, and thus it will no longer be able to fix the object.

[0005] For this reason, a kind of anti-dropping combined U-shaped nail is proposed. Utility Model Content

[0006] In view of this, the utility model provides an anti-dropping combined U-shaped nail to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is implemented as follows: an anti-dropping combined U-shaped nail, comprising a nail, a shell is arranged on the top of the nail, and a handle is movably connected to the left side of the shell;

[0008] A fixing mechanism is provided in the inner cavity of the pin, and the fixing mechanism includes a first bidirectional screw, which is fixedly installed in the inner cavities of the two pins, and the upper and lower sides of the surface of the first bidirectional screw are threadedly connected with first screw blocks, and the left and right sides of the upper and lower sides of the inner cavity of the pin are provided with inclined blocks, and the outer sides of the four inclined blocks are fixedly installed with hard springs, and the outer sides of the four hard springs are fixedly connected to the outer side of the inner cavity of the pin, and the outer sides of the four inclined blocks are fixedly installed with auxiliary insertion rods, and the top of the first bidirectional screw is fixedly connected with a knob, and the left and right sides of the top of the knob are threadedly connected with fixing bolts, and the top of the pin is fixedly installed with a connecting rod.

[0009] Further preferably, screw grooves are provided on both left and right sides of the top of the pin, and the bottoms of the two fixing bolts are threadedly connected to the inner cavities of the two screw grooves.

[0010] Further preferably, an anti-slip groove is provided on the surface of the pin, and the anti-slip groove is threaded.

[0011] Further preferably, slots are provided around the inner cavity of the pin, and the eight auxiliary insertion rods are movably connected in the inner cavities of the eight slots.

[0012] Further preferably, both front and rear sides of the inner cavity of the nail are provided with limiting grooves, and both front and rear sides of the two first screw blocks are slidably connected in the inner cavities of the two limiting grooves.

[0013] Further preferably, a second bidirectional screw is fixedly connected to the right side of the handle, second screw blocks are threadedly connected to the left and right sides of the surface of the second bidirectional screw, and the tops of the eight connecting rods are fixedly connected to the bottoms of two of the second screw blocks.

[0014] Further preferably, limiting rods are fixedly installed on both the front and rear sides of the inner cavity of the shell, and the two limiting rods are slidably connected to the inner surfaces of the two second screw blocks.

[0015] Further preferably, a pull rod is fixedly mounted on the top of the shell, and a protective pad is sleeved on the surface of the pull rod.

[0016] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0017] 1. The utility model provides a fixing mechanism, and by turning the knob, the knob drives the first bidirectional screw to rotate. As the first bidirectional screw rotates, the first screw block moves outward. At this time, the inclined block is pushed outward due to the movement of the first screw block, and the hard spring is deformed due to the extrusion of the inclined block. At the same time, due to the movement of the inclined block, the secondary insertion rod moves outward, so that the secondary insertion rod is inserted into the soil, completing the fixing effect of the pin, improving the stability of the pin inserted in the soil, and effectively reducing the possibility that the space for the pin to be inserted in the soil becomes larger due to accidental collisions caused by external factors, thereby causing the pin to easily fall off from the soil.

[0018] Second, the utility model can limit the knob by setting the screw groove, so as to prevent the knob from rotating due to interference from external factors, thereby affecting the stability of the pin inserted into the soil. By setting the anti-skid groove, since the anti-skid groove is in a threaded shape, the tightness of the pin after being inserted into the soil is improved. By setting the slot, the movement of the secondary plug rod can be limited to prevent the secondary plug rod from changing direction when moving, thereby affecting the stability of the pin inserted into the soil. By setting the limiting groove, the movement of the first screw block can be limited to prevent the first screw block from offsetting when moving, thereby reducing the stability of the pin inserted into the soil. By setting the second bidirectional screw rod and the second screw block, the spacing between the pins can be easily adjusted, and the spacing of the pins can be adjusted according to the width of the object to be fixed, thereby improving the applicable scope of the pins. By setting the limiting rod, the second screw block can be limited to prevent the second screw block from changing direction when moving, thereby affecting the adjustment of the spacing of the pins. By setting the pull rod and the protective pad, the whole device can be easily lifted by hand, thereby improving the convenience of carrying the device.

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, the embodiment of the utility model provides an anti-dropping combined U-shaped nail, comprising a nail 1, a shell 3 is arranged on the top of the nail 1, and a handle 4 is movably connected to the left side of the shell 3;

[0031] A fixing mechanism 2 is provided in the inner cavity of the nail 1, and the fixing mechanism 2 includes a first bidirectional screw 201, which is fixedly installed in the inner cavities of the two nails 1. The upper and lower sides of the surface of the first bidirectional screw 201 are threadedly connected with first screw blocks 202, and the left and right sides of the upper and lower sides of the inner cavity of the nail 1 are provided with inclined blocks 203, and the outer sides of the four inclined blocks 203 are fixedly installed with hard springs 204, and the outer sides of the four hard springs 204 are fixedly connected to the outer side of the inner cavity of the nail 1, and the outer sides of the four inclined blocks 203 are fixedly installed with auxiliary insertion rods 205, and the top of the first bidirectional screw 201 is fixedly connected with a knob 206, and the left and right sides of the top of the knob 206 are threadedly connected with fixing bolts 207, and the top of the nail 1 is fixedly installed with a connecting rod 212.

[0032] By setting the fixing mechanism 2, by rotating the knob 206, the knob 206 drives the first bidirectional screw 201 to rotate. With the rotation of the first bidirectional screw 201, the first screw block 202 moves outward. At this time, the inclined block 203 is pushed outward due to the movement of the first screw block 202, and the hard spring 204 is deformed due to the extrusion of the inclined block 203. At the same time, due to the movement of the inclined block 203, the auxiliary insertion rod 205 moves outward, so that the auxiliary insertion rod 205 is inserted into the soil, completing the fixing effect of the nail 1, improving the stability of the nail 1 inserted in the soil, and effectively reducing the possibility that the space for the nail 1 to be inserted in the soil becomes larger due to accidental collisions caused by external factors, thereby causing the nail 1 to easily fall off from the soil.

[0033] Example 2

[0034] In one embodiment, screw grooves 208 are provided on both sides of the top of the pin 1, the bottoms of the two fixing bolts 207 are threadedly connected to the inner cavities of the two screw grooves 208, the surface of the pin 1 is provided with anti-slip grooves 209, the anti-slip grooves 209 are threaded, and the inner cavity of the pin 1 is provided with slots 210 around it. The eight auxiliary insertion rods 205 are movably connected to the inner cavities of the eight slots 210, and the front and rear sides of the inner cavity of the pin 1 are provided with limiting grooves 211. The front and rear sides of the two first screw blocks 202 are slidable. It is movably connected to the inner cavity of the two limit grooves 211, and a second bidirectional screw 5 is fixedly connected to the right side of the handle 4. The left and right sides of the surface of the second bidirectional screw 5 are threadedly connected to the second screw blocks 6, and the tops of the eight connecting rods 212 are fixedly connected to the bottoms of the two second screw blocks 6. Limit rods 7 are fixedly installed on the front and back sides of the inner cavity of the shell 3, and the two limit rods 7 are slidably connected to the inner surfaces of the two second screw blocks 6. A pull rod 8 is fixedly installed on the top of the shell 3, and a protective pad 9 is provided on the surface of the pull rod 8.

[0035] By providing the screw groove 208, the knob 206 can be limited to prevent the knob 206 from rotating due to interference from external factors, thereby affecting the stability of the nail 1 inserted into the soil. By providing the anti-skid groove 209, since the anti-skid groove 209 is in a threaded shape, the tightness of the nail 1 after being inserted into the soil is improved. By providing the slot 210, the movement of the secondary insertion rod 205 can be limited to prevent the secondary insertion rod 205 from changing direction when moving, thereby affecting the stability of the nail 1 inserted into the soil. By providing the limiting groove 211, the movement of the first screw block 202 can be limited. The second screw block 202 is positioned to avoid deviation when it moves, thereby reducing the stability of the pin 1 inserted into the soil. By setting the second bidirectional screw rod 5 and the second screw block 6, the spacing between the pins 1 can be easily adjusted, and the spacing of the pins 1 can be adjusted according to the width of the object to be fixed, thereby improving the application range of the pin 1. By setting the limiting rod 7, the second screw block 6 can be limited to avoid the direction of the second screw block 6 changing when it moves, thereby affecting the adjustment of the spacing of the pins 1. By setting the pull rod 8 and the protective pad 9, the whole device can be easily lifted by hand, thereby improving the convenience of carrying the device.

[0036] When the utility model is working: first, according to the size of the object, grasp the handle 4 and rotate it. As the handle 4 rotates, the second bidirectional screw 5 rotates synchronously. At this time, the second screw block 6 moves along the surface of the second bidirectional screw 5 to complete the addition of the spacing of the nail 1. Then, after the nail 1 is inserted into the soil, the knob 206 is turned. At this time, the knob 206 drives the first bidirectional screw 201 to rotate. As the first bidirectional screw 201 rotates, the first screw block 202 moves outward. At this time, the inclined block 203 is pushed outward due to the movement of the first screw block 202, and the hard spring 204 is deformed due to the extrusion of the inclined block 203. At the same time, due to the movement of the inclined block 203, the auxiliary insertion rod 205 moves outward, so that the auxiliary insertion rod 205 is inserted into the soil, completing the fixing effect of the nail 1.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
