Description

Technical Field

[0001] This utility model relates to the field of horticulture, specifically a long-lasting and stable horticultural ground cover fixing device. Background Technology

[0002] Gardening ground cover is a type of ground cover laid in gardening environments. This type of ground cover has the effects of blocking sunlight, leveling the ground, and blocking weeds. However, as a type of fabric, gardening ground cover is easily blown away, so it needs to be fixed with a special kind of nail.

[0003] Traditional gardening ground cover fixing devices generally come in several types, among which straight nails and U-shaped nails are widely used. Straight nails are convenient to use and easy to remove, and they last a long time and are less likely to lose their fixing effect due to external forces.

[0004] Straight garden mat nails are convenient to use and effective for a long time. However, as nails used in gardening, they have poor compatibility. For example, if the soil where the mat nails are needed is poor and requires harder nails, but the user buys nails suitable for good soil, or vice versa, the user buys nails suitable for poor soil. As a simple device, garden mat fixing devices cannot meet the various usage scenarios required by users. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this utility model provides a long-lasting and stable garden ground cover fixing device, which solves the problem in the background technology that "the long-lasting and stable effect is greatly reduced because general long-lasting and stable garden ground cover fixing devices cannot adapt to various soil types".

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-lasting and stable garden ground cover fixing device, comprising a soil-breaking nail, an outer rod body fixedly connected to the top of the soil-breaking nail, an outer rod groove formed on the inner wall of the outer rod body, a threaded groove formed on the inner wall of the outer rod body, a limiting plate fixedly connected to the top of the outer rod body, a screw thread threadedly connected to the inner wall of the outer rod body through the threaded groove, an inner rod body fixedly connected to the outer wall of the screw thread, and an inner rod groove formed on the inner wall of the inner rod body.

[0007] As a further description of the above technical solution:

[0008] The top of the inner rod is fixedly connected to a torsion shaft.

[0009] As a further description of the above technical solution:

[0010] A knob is fixedly connected to the top of the torsion shaft.

[0011] As a further description of the above technical solution:

[0012] The outer rod has a rectangular groove, and there are four grooves in total, which are evenly distributed on the inner wall of the outer rod.

[0013] As a further description of the above technical solution:

[0014] The inner rod slot is rectangular in shape, and there are four inner rod slots in total, which are evenly distributed on the inner wall of the inner rod.

[0015] As a further description of the above technical solution:

[0016] The four outer rod slots are adapted to the four inner rod slots.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the knob is provided with anti-slip serrations.

[0019] As a further description of the above technical solution:

[0020] The bottom of the limiting plate abuts against the top of the inner rod.

[0021] This utility model provides a long-lasting and stable garden ground cover fixing device. It has the following beneficial effects:

[0022] (1) The long-lasting and stable gardening ground cover fixing device can select different modes according to different ground soil conditions. When the ground soil is good, such as soft soil or fine sand, the knob can be turned to switch to the hollow mode. In this mode, after the nail is driven into the ground, the soil will enter the gardening nail, achieving a more stable and longer-lasting effect. The solid mode is more suitable for soil with poor soil conditions, such as sandy soil and silty soil.

[0023] (2) Considering that switching modes by rotation may cause the nail itself to vibrate when the nail is driven in or cause the hollow mode to become a solid mode due to other factors, threads are provided on the outer rod and the inner rod so that the outer rod and the inner rod are threadedly connected. Only by rotating with a certain force can the mode be switched, and this threaded structure can prevent it from easily changing modes due to external force. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a long-lasting and stable horticultural ground cover fixing device, including a soil-piercing nail 1, which is used to penetrate the soil to provide initial fixation. An outer rod 2 is fixedly connected to the top of the soil-piercing nail 1, and the outer rod 2 serves as the main support structure of the fixing device. An outer rod groove 3 is formed on the inner wall of the outer rod 2, which allows soil to enter and increase friction. A threaded groove 4 is formed on the inner wall of the outer rod 2, which is used to connect with an inner rod 7. A limiting plate 5 is fixedly connected to the top of the outer rod 2, which limits the depth of the outer rod 2's penetration. A screw thread 6 is threadedly connected to the inner wall of the outer rod 2 through the threaded groove 4. The screw thread 6 cooperates with the threaded groove 4 of the outer rod 2 to achieve connection. An inner rod 7 is fixedly connected to the outer wall of the screw thread 6, and the inner rod 7 is connected to the outer rod 2 through the screw thread 6. An inner rod groove 8 is formed on the inner wall of the inner rod 7, which also allows soil to enter and increases the overall friction.

[0033] Reference Figures 2-4The inner rod body 7 has a torsion shaft 9 fixedly connected to its top end. The torsion shaft 9 is used to transmit rotational force. A knob 10 is fixedly connected to the top end of the torsion shaft 9. The knob 10 makes it easy for the operator to apply rotational force. The outer rod slot 3 is rectangular in shape. The rectangular slot facilitates soil entry and locking. There are four outer rod slots 3 in total. The four outer rod slots 3 are evenly distributed to enhance grip. The four outer rod slots 3 are evenly distributed on the inner wall of the outer rod body 2. The even distribution ensures force balance. The inner rod slot 8 is rectangular in shape. The shape of the inner rod slot 8 matches that of the outer rod slot 3. There are four inner rod slots 8 in total. The four inner rod slots 8 are evenly distributed to enhance grip. The four inner rod slots 8 are evenly distributed on the inner wall of the inner rod body 7.

[0034] Reference Figures 3-5 The four outer rod slots 3 are adapted to the four inner rod slots 8, and the inner and outer slots are aligned to form a continuous channel. The outer wall of the knob 10 is provided with anti-slip teeth, which makes it easier for users to operate. The bottom of the limiting plate 5 abuts against the top of the inner rod body 7. When the limiting plate 5 abuts against the top of the inner rod body 7, the knob 10 cannot be rotated any further.

[0035] Working principle: Drive the long-lasting and stable gardening ground cover fixing device into the location where the gardening ground cover needs to be fixed. If the soil is relatively hard, tighten the knob 10 inward and use the solid mode to drive the gardening ground cover deep into the soil. If the soil is relatively soft, loosen the knob 10 outward and switch to the openwork mode to drive the fixing device into the gardening ground cover deep into the soil. The openwork structure can play a more long-lasting and stable role in soft soil.

[0036] When the solid mode is needed, rotate knob 10 to offset the outer rod slot 3 from the inner rod slot 8. When the outer rod slot 3 from the outer rod slot 3 from the inner rod slot 8 from the inner rod slot 8 from the outer rod slot 3, the entire fixing device is in a solid state. At this time, it can be driven into a place with relatively hard soil to achieve the fixing effect of gardening ground cover. If the soil where it is to be used is relatively soft, then you can rotate knob 10 to align the outer rod slot 3 from the outer rod slot 3 from the inner rod slot 8. When the outer rod slot 3 from the outer rod slot 3 from the inner rod slot 8 from the inner rod slot 8 from the outer rod slot 3, the entire device is in a hollow state. When the hollow fixing device is driven into the relatively soft soil, the soft soil will gradually enter the hollow interior of the device from the outer rod slot 3 and the inner rod slot 8 over time. When the soil fills the interior of the device, the stability of the device is maximized. The hollow mode can fix the gardening ground cover for a long time and stably even in soft soil.

[0037] Considering that using simple rotation to switch modes is too rudimentary, and that the nails may change from a hollow mode to a solid mode over time or due to external force, or the outer rod and inner rod may jam, causing the effect to fail, a threaded groove 4 and a screw thread 6 are provided. When it is necessary to switch modes, the knob 10 is rotated. The knob 10 will drive the torsion shaft 9 fixedly connected to the knob 10. The torsion shaft 9 will drive the inner rod 7 and the screw thread 6 fixedly connected to the inner wall of the inner rod 7. The screw thread 6 will slide in the threaded groove 4. Because of the existence of the threaded groove 4 and the screw thread 6, the switching method of this device becomes stable. Only a certain amount of force is required to switch modes. When the threaded groove 4 and the screw thread 6 are tightened, common external forces will hardly affect them. At this time, the device can securely fix the gardening ground cover that needs to be fixed for a long time.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
