Description

Technical Field

[0001] This utility model relates to the field of artificial turf, and more specifically, to a height-adjustable artificial turf. Background Technology

[0002] Artificial turf is a ground cover material made of synthetic materials that simulates natural grass. It is primarily composed of high-molecular polymers such as polyethylene (PE) and polypropylene (PP), manufactured through processes like drawing, weaving, and tufting. It features a realistic appearance, soft touch, wear resistance, durability, UV resistance, and anti-aging properties, effectively resisting damage from harsh weather and frequent use. Compared to natural grass, artificial turf requires less frequent watering, fertilization, and mowing, significantly reducing maintenance costs and water consumption.

[0003] However, existing artificial turf is usually fixed in height after installation, making it difficult to adjust according to actual usage needs. In some special scenarios, such as indoor exhibitions and temporary event venues, it is necessary to adjust the height of the turf according to the venue design or event theme, and existing fixed-height artificial turf cannot achieve this function.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a height-adjustable artificial turf. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a height-adjustable artificial turf.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable artificial turf, comprising a base layer and an artificial turf layer installed on the base layer, wherein an adjustment component is installed at the bottom end of the base layer; The adjustment assembly includes straight-line maintaining components located at the four corners of the bottom of the base layer and a frame-shaped base. Each straight-line maintaining component is fixedly connected to a screw A at its bottom. Each of the four corners of the top of the frame-shaped base has a through hole A for the screw A to pass through. A nut is installed at the part of the screw A that passes through the through hole A. An annular plate is fitted on the part of the screw A that does not pass through the through hole A. The straight-line maintaining components are used to maintain the vertical linear movement of the annular plate fitted on the screw A and to fix its height after movement.

[0007] Preferably, the straightness maintaining component includes sliding rods fixed at the four corners of the bottom of the base layer, and sliding sleeves are slidably connected to the outer side walls of the sliding rods. The two sides of the sliding sleeves are fixed to the annular plate through connecting plates, and the screw A is fixed to the bottom end of the sliding rod.

[0008] Preferably, the surface of the slide rod has multiple screw holes arranged in a vertical array, and the surface of the slide sleeve has a through hole B.

[0009] Preferably, the surface of the sliding sleeve is fixedly connected to guide rails for sliding of the slider on both sides of the through hole B, the sliders are fixedly connected to a bearing, and a rotating rod is fixedly connected to the inner ring of the bearing. The end of the rotating rod is fixedly connected to a screw B that is aligned with the through hole B and threaded to the screw hole.

[0010] Preferably, the head of the rotating rod is fixedly connected to a handle that facilitates its rotation.

[0011] Preferably, the top and front sides of the frame-shaped base are provided with through slots, the bottom and front sides of the base layer are fixedly connected with scales that can pass through the through slots, and the bottom of the frame-shaped base is fixedly connected with arrows pointing to the scales on the scales.

[0012] Preferably, male snap fasteners are installed at the four bottom corners of the artificial turf layer, and grooves are provided at the four top corners of the base layer, with female snap fasteners installed on the inner bottom wall of the grooves, and friction textures are provided on the top of the base layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the height of the artificial turf needs to be adjusted, this utility model uses a linear maintaining component to constrain the linear movement of the annular plate, allowing it to move only up and down along screw A. The annular plate is moved to an appropriate height relative to screw A as needed, and then fixed at that height relative to screw A. It is then pressed against the top of the top plate of the frame base. Next, by turning the nut clockwise, the nut moves upward along screw A, thus abutting against the bottom of the top plate of the frame base. In this way, the nut, together with the annular plate, clamps the top plate of the frame base from both the top and bottom, thereby fixing the distance between the base layer and the artificial turf layer on it, and the frame base. This allows for the adjustment of the height of the artificial turf layer installed on the base layer, meeting the needs for turf height adjustment in special scenarios such as indoor exhibitions and temporary event venues, thus solving the problems in the background technology. 2. This utility model designs the artificial turf layer and the base layer as a detachable connection. When the artificial turf layer is locally worn, has stains that are difficult to clean, or is damaged, it can be disassembled separately for repair, cleaning, or replacement, which greatly reduces maintenance costs and time costs. Secondly, in terms of adaptability to usage scenarios, different activities have different requirements for turf materials, appearance, etc. The detachable design makes it easy to quickly replace different types of artificial turf layers, flexibly meeting diverse usage needs. 3. This utility model replaces screw fixing with the design of guide rail, slider, bearing, rotating rod, screw B, etc. Compared with screw, the above components will not detach from the sliding sleeve, avoiding the problem of loss.

[0016] like Figure 1-6 As shown, this utility model provides a height-adjustable artificial turf, including a base layer 1 and an artificial turf layer 2 installed on the base layer 1, with an adjustment component 3 installed at the bottom end of the base layer 1; The adjustment assembly 3 includes a linear support component 301 and a frame base 302 located at the four corners of the bottom of the base layer 1. Each linear support component 301 is fixedly connected to a screw A303 at its bottom. Each of the four corners of the top of the frame base 302 has a through hole A3021 for the screw A303 to pass through. A nut 304 is installed at the part of the screw A303 that passes through the through hole A3021. An annular plate 305 is fitted on the part of the screw A303 that does not pass through the through hole A3021. The linear support component 301 is used to maintain the vertical linear movement of the annular plate 305 fitted on the screw A303 and to fix its height after movement.

[0017] Addressing the problem of fixed turf height in existing technologies, this invention achieves height adjustment through the adjustment component 3. When the artificial turf height needs adjustment, the linear support component 301 constrains the linear movement of the annular plate 305, allowing it to move only up and down along the screw A303. Based on the required turf height, the annular plate 305 is moved to an appropriate height relative to the screw A303. After moving, the height of the annular plate 305 relative to the screw A303 is fixed, and then it is pressed against the top of the frame base 302. Next, by turning the nut 304 clockwise, the nut 304 moves upward along the screw A303, thus abutting against the bottom of the top plate of the frame base 302. In this way, the nut 304, together with the annular plate 305, clamps the top plate of the frame base 302 from both above and below, thereby fixing the distance between the base layer 1 and the artificial turf layer 2 on it and the frame base 302. This allows for height adjustment of the artificial turf layer 2 installed on the base layer 1, meeting the need for rapid turf height adjustment in special scenarios such as indoor exhibitions and temporary event venues.

[0018] The linear support component 301 includes slide rods 3011 fixed at the four corners of the bottom of the base layer 1, and slide sleeves 3012 are slidably connected to the outer side walls of the slide rods 3011. The two sides of the slide sleeves 3012 are fixed to the annular plate 305 through connecting plates 3013. The screw A 303 is fixed to the bottom end of the slide rods 3011. Multiple screw holes 3014 are arranged in a vertical array on the surface of the slide rods 3011. The surface of the slide sleeves 3012 has a through hole B 3015. The two sides of the through hole B 3015 on the surface of the slide sleeves 3012 are fixedly connected to guide rails 4 for sliding of the sliders 5. The sliders 5 are fixedly connected to the bearings 5. The inner ring of the bearing 6 is fixedly connected to a rotating rod 7. The end of the rotating rod 7 is fixedly connected to a screw B8 that is aligned with the through hole B 3015 and threaded to the screw hole 3014. The head of the rotating rod 7 is fixedly connected to a handle 9 for easy rotation.

[0019] That is, to adjust the height as needed, the annular plate 305, which is sleeved on the screw A303, is pulled up or down along the screw A303. The annular plate 305 drives the sliding sleeve 3012 to move up or down through the connecting plate 3013. During this process, the sliding sleeve 3012 moves linearly up and down along the sliding rod 3011 to maintain the linear movement of the annular plate 305 relative to the screw A303, so that it moves to an appropriate height relative to the screw A303 (the height to be adjusted according to the lawn). At this time, the bearing 6 pushes the screw B8 to move towards the sliding sleeve 3012, and at the same time, the bearing 6 drives the slider 5 to move. Slider 5 slides along guide rail 4, causing screw B8 to pass through through hole B3015 on sleeve 3012. Then, handle 9 is rotated clockwise, causing handle 9 to rotate rod 7. Rotating rod 7 drives the inner ring of bearing 6 to rotate, and the inner ring of bearing 6 rotates along with its outer ring, thus providing rotational support for rotating rod 7. Simultaneously, rotating rod 7 drives screw B8 to rotate clockwise, installing it into the corresponding height screw hole 3014. (During the process of screw B8 being installed into screw hole 3014, bearing 6 will then move towards sleeve 3012, thereby causing slider 5 to slide along guide rail 4.) This allows sleeve 3012 to... Fixed at the height corresponding to the sliding rod 3011, thus fixing the height of the annular plate 305 relative to the screw A303. Then, the annular plate 305 is pressed tightly against the top of the top plate of the frame base 302. Next, by turning the nut 304 clockwise, the nut 304 moves upward along the screw A303, thereby abutting against the bottom of the top plate of the frame base 302. In this way, the nut 304, together with the annular plate 305, clamps the top plate of the frame base 302 from both above and below, thereby fixing the distance between the base layer 1 and the artificial turf layer 2 on it and the frame base 302, thus achieving the desired height of the artificial turf layer 2 installed on the base layer 1. To adjust the height, turn handle 9 counterclockwise to remove screw B8 from screw hole 3014 (at this time, slider 5 moves away from sliding sleeve 3012 along guide rail 4). Then turn nut 304 counterclockwise so that nut 304 moves downward along screw A303. This allows you to readjust the distance between artificial turf layer 2, base layer 1 and frame base 302, thereby readjusting the height of artificial turf layer 2 on base layer 1. The design of guide rail 4, slider 5, bearing 6, rotating rod 7, screw B8, etc., replaces screw fixing. Compared with screws, the above components will not detach from sliding sleeve 3012, avoiding the problem of loss.

[0020] Furthermore, the top and front sides of the frame base 302 are provided with through slots 3022, and the bottom and front sides of the base layer 1 are fixedly connected with scales 10 that can pass through the through slots 3022. The bottom of the frame base 302 is fixedly connected with an arrow 11 pointing to the scale on the scale 10. When adjusting the height of the artificial turf layer 2 on the base layer 1 (before the height is fixed), the scale 10 will move up and down along the through slots 3022 on the frame base 302. By pointing to the scale on the scale 10 at the bottom of the base layer 1 through the arrow 11 on the frame base 302, the operator can intuitively read the current turf height value, achieve precise adjustment, and avoid height errors caused by operation based on experience. This design is particularly suitable for professional sports fields or exhibition venues with strict requirements on lawn height. One graduation on the scale 10 corresponds to one screw hole 3014 on the slide rod 3011. At the same time, this utility model designs the artificial turf layer 2 and the base layer 1 as a detachable connection (snap-fit ​​connection). When the artificial turf layer 2 is locally worn, has stains that are difficult to clean, or is damaged, it can be disassembled separately for repair, cleaning, or replacement, which greatly reduces maintenance and time costs. Secondly, in terms of adaptability to different usage scenarios, different activities have different requirements for turf materials and appearance. The detachable design makes it easy to quickly replace different types of artificial turf layers 2, flexibly meeting diverse usage needs.

[0021] The following is the specific structure of the detachable connection between the base layer 1 and the artificial turf layer 2: Each of the four bottom corners of the artificial turf layer 2 is equipped with a male snap fastener 12, and each of the four top corners of the base layer 1 is provided with a groove 101. A female snap fastener 13 is installed on the inner bottom wall of the groove 101. The top of the base layer 1 has friction grooves. When installing the artificial turf layer 2, align the male snap fasteners 12 at its four bottom corners with the female snap fasteners 13 in the grooves 101 at the top of the base layer 1. During installation, press down to lock the male snap fasteners 12 and female snap fasteners 13 together, thus firmly fixing the artificial turf layer 2 to the base layer 1 and ensuring that the two will not easily separate during use. When it is necessary to disassemble the artificial turf layer 2, apply a counterforce to the male and female clips 12 and 13 to release the locking state, and the artificial turf layer 2 can be removed from the base layer 1, achieving quick disassembly and assembly. The design of the groove 101 provides installation space for the male and female clips 12 and 13, so that when the base layer 1 and the artificial turf layer 2 are connected by clips, the top surface of the base layer 1 and the bottom surface of the artificial turf layer 2 can be tightly attached to each other. Combined with the anti-slip texture on the top of the base layer 1, it can effectively reduce the shaking or displacement of the artificial turf layer 2 during use.
