[0002] As people's living standards continue to improve, they have higher and higher requirements for leisure environments. Private gardens, parks, playgrounds and other places have become the best places for people to relax and have fun. However, the lawns in private gardens, parks and playgrounds need to be maintained from time to time to ensure their beauty. Currently, lawn mowers are usually used to replace manual maintenance. However, the traditional lawn mowing method usually uses a hanging lawn mower, which increases the overall workload of workers. Therefore, ride-on lawn mowers have been rapidly adopted.

[0003] In the production process of ride-on lawnmowers, the seat needs to be installed on the frame via a rail to accommodate riders of different body types. However, the rail does not have a fastening structure, resulting in poor stability of the seat after installation. Furthermore, the external fixing structure is not well-suited to the seat, which may cause the seat to slide during lawnmower operation, reducing the safety of the lawnmower. Therefore, we need to propose a rail fastening device. Utility Model Content

[0004] The purpose of this utility model is to provide a track fastening device, which, by setting a fastening structure on the installation track, facilitates the limiting of the position of the slider on the slide rail, further improves the stability of the track after it is fixed, and ensures the stability of the driver, thereby solving the problems mentioned in the background art.

[0026] 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a track fastening device, including a fixed track 10, a movable slide rail 20, a connecting piece 30 and a positioning piece 40;

[0028] The movable slide rail 20 is slidably installed above the fixed rail 10, and two sets of reinforcing beams 50 are installed on the fixed rail 10.

[0029] The fixed track 10 includes two sets of bottom beams 101 for sliding of the movable track. Two sets of reinforcing beams 50 are welded between the two sets of bottom beams 101. The bottom beams 101 have a cavity 107 for mounting the positioning component 40. The connecting component 30 is installed between the two sets of bottom beams 101 to adjust the position of the positioning component 40. The positioning component 40 is used to tighten the movable slide rail 20 after the position is adjusted.

[0030] In this embodiment, as Figure 2 and Figure 5As shown, the positioning member 40 includes a base plate 401. Multiple sets of protrusions 405 are fixedly connected to the upper surface of the base plate 401. The multiple sets of protrusions 405 are arranged at equal intervals and are all arranged on the same straight line. A step block 404 is fixedly connected to one side of the base plate 401. The side view of the step block 404 is arranged in a right trapezoidal shape. The multiple sets of protrusions 405 can increase the contact area with the movable slide rail 20, thereby improving the positioning stability of the movable slide rail 20. The step block 404 is pushed to move by the movement of the connecting member 30, thereby causing the step block 404 to drive the base plate 401 to compress the multiple sets of reset members, causing the base plate 401 to drive the multiple sets of protrusions 405 to descend, thereby facilitating the disengagement of the protrusions 405 from the movable slide rail 20, releasing the restriction on the movable slide rail 20, thereby adjusting the position of the movable slide rail 20 and improving the convenience of adjusting the position of the movable slide rail 20.

[0031] In a further preferred embodiment, such as Figure 5 As shown, multiple sets of reset components are fixedly connected to the lower surface of the substrate 401, and each set of reset components consists of a telescopic rod 402 and a spring 403. The spring 403 is sleeved on the outside of the telescopic rod 402. The multiple sets of reset components can increase the elasticity after the protrusion 405 is disengaged from the movable slide rail 20, thereby facilitating the fixing of the adjusted slide rail by the protrusion 405, improving the efficiency of fixing the movable slide rail 20. By equidistantly setting multiple sets of reset components, the substrate 401 can be raised and lowered horizontally, reducing the failure rate.

[0032] Furthermore, such as Figure 3 As shown, the connector 30 includes a protective sleeve 301 fixedly connected between two sets of bottom beams 101. A crossbar 302 is slidably arranged in the inner cavity of the protective sleeve 301. The two ends of one side of the crossbar 302 are respectively set in the bottom cavity 107 of the two sets of bottom beams 101. Both ends of one side of the crossbar 302 are fixedly connected to push blocks 303 that slide with the step blocks 404. When the crossbar 302 moves, it drives the push blocks 303 to press the inclined surface of the step blocks 404, so that the step blocks 404 are subjected to force and drive the base plate 401 to descend. This releases the positioning component 40 from fixing the movable slide rail 20, thereby facilitating the adjustment of the seat position installed on the movable slide rail 20, making it convenient for lawn mowers of different body types to sit.

[0033] like Figure 3 As shown, a pressure column 304 that penetrates the protective sleeve 301 is fixedly connected to the other side of the crossbar 302. The pressing end of the pressure column 304 is provided with a circular pressure plate. The pressure plate (not shown in the figure) can reduce the discomfort when applying pressure and improve the comfort of operation. The pressure plate can drive the pressure column 304 to adjust the position of the crossbar 302. The overall operation is simple and the practicality is improved. Pressing the pressure plate can release the positioning part 40 from fixing the movable slide rail 20. Conversely, releasing the pressure plate can allow the positioning part 40 to reposition the movable slide rail 20 under the action of the reset part, thereby improving the stability of the movable slide rail 20.

[0034] Preferred, such as Figure 4 As shown, the movable slide rail 20 includes a connecting beam 201 and two sets of guide beams 202. The two sets of guide beams 202 are welded to both ends of the connecting beam 201. The top view of the connection between the connecting beam 201 and the two sets of guide beams 202 is arranged in an I-shape. The I-shaped structural design of the connecting beam 201 and the two sets of guide beams 202 improves the overall strength of the movable slide rail 20, thereby increasing its service life.

[0035] In addition, such as Figure 2 As shown, the upper surfaces of both sets of bottom beams 101 are provided with mounting grooves 102 for sliding guide beams 202, and rollers 103 are rotatably mounted on both sides of the inner cavity of the mounting grooves 102. The guide beams 202 are provided with grooves 203 on both sides for rolling multiple sets of rollers 103. The rollers 103 in the mounting grooves 102 facilitate the sliding of the guide beams 202 within the mounting grooves 102, reducing the resistance of the movable slide rail 20 during sliding, reducing the intensity of adjusting the riding lawnmower seat, and improving practicality. The design of the grooves 203 on the guide beams 202 reduces the weight of the movable slide rail 20, thereby reducing the production cost of the movable slide rail 20.

[0036] Secondly, such as Figure 2 As shown, the bottom of the mounting groove 102 is provided with through holes 106 for multiple sets of protrusions 405 to pass through, and the lower surface of the guide beam 202 is provided with locking holes 204 for multiple sets of protrusions 405 to be inserted. The use of multiple sets of through holes facilitates the installation and guidance of the protrusions 405, and prevents the protrusions 405 from falling out of the through holes 106 and getting stuck in the bottom groove, thus improving practicality.

[0037] It is worth noting that, such as Figure 2 and Figure 6 As shown, a first positioning hole 104 is provided at one end of the upper surface of the bottom beam 101, and a second positioning hole 105 is provided at the end of the mounting groove 102 away from the first positioning hole 104. The fixed track 10 can be easily installed on the frame of the lawnmower through the first positioning hole 104 and the second positioning hole 105, thereby improving the stability of the fixed track 10 installation. At the same time, both sets of reinforcing beams 50 are provided with stepped holes for bolt installation, further improving the stability of the fixed track 10 after installation.

[0038] like Figure 4 As shown, a T-beam 205 is welded to the upper surface of the guide beam 202, and multiple sets of bolt holes are provided on the T-beam 205. By providing bolt holes on the guide beam 202, it is convenient to install the movable slide rail 20 at the bottom of the seat, which improves the ease of disassembly and assembly.

[0039] In use, pressure is applied to the pressure column 304, causing it to drive the crossbar 302 to slide within the protective sleeve 301. The crossbar 302, through the push block 303, applies pressure to the step block 404 on the base plate 401, thereby causing the entire base plate 401 to descend within the bottom cavity 107. This causes the protrusion 405 on the base plate 401 to disengage from the locking hole 204 of the movable slide rail 20 and be housed within the through hole 106. Simultaneously, the spring 403 of the compression reset component on the base plate 401 increases its elasticity. The movable slide rail 20 connects to the bottom beam 107 via the grooves 203 on both sides of the guide beam 202. The rollers 103 inside the mounting groove 102 make contact, allowing for smooth sliding and position adjustment. When the target position is reached, the pressure column 304 is released, and the base plate 401 is lifted to the top of the bottom cavity 107 under the action of the springs 403 of multiple reset components. Multiple protrusions 405 are guided through the through hole 106 and inserted into the locking holes 204 on the guide beam 202, re-fixing the movable slide rail 20 and completing the positioning and fastening of the movable slide rail 20. The whole machine is easy to use and allows workers of different body types to quickly adjust the seating space on the lawnmower, improving its practicality.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
