Description

Technical Field

[0001] The utility model relates to the technical field of gardening, in particular to a walking device capable of adjusting the tension of a belt pulley. Background Art

[0002] A lawn mower is also called a weed cutter, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. The lawn mower uses multiple mechanisms to cooperate with each other to perform mowing operations. The walker is one of the important parts of the lawn mower, which controls the movement of the lawn mower. The walker is generally used in conjunction with a pulley, which drives the pulley to rotate and then operates the lawn mower.

[0003] However, after the existing walker is connected to the pulley, the pulley has a certain degree of tightness after installation. However, as the pulley continues to work, the belt installed on the pulley is gradually stretched as the working time increases, causing the belt to gradually loosen. If it is not handled in time, the belt is very easy to fall off the pulley during work and cause damage to related components. Therefore, a walker with adjustable pulley tension is proposed to solve the above problem. Utility Model Content

[0010] Preferably, the rotating mechanism comprises a turntable rotatably connected to the end of the mounting rod, the end of the threaded rod is fixed to the end of the turntable, and the other end of the threaded rod is rotatably connected to the end of the adjusting handle.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] 1. In the utility model, the tension of the pulley is adjusted by toggling the adjusting handle, thereby preventing the pulley from being too loose or too tight and causing the pulley to break. When the adjusting handle is working, the installation rod is inserted into the connecting tube, and the limiting ball is initially retracted into the installation groove under the pressure of the spring. When the installation rod is inserted into the connecting tube and reaches the limiting groove, the limiting ball is popped out into the limiting groove under the action of the spring to form a snap-fit ​​fixation, which is convenient for quick installation and replacement of the adjusting handle, and at the same time convenient for adjusting the length of the adjusting handle and the connecting tube, which is more convenient to use.

[0024] Example: Reference Figure 1-7 The walking device shown in the figure can adjust the tension degree of the pulley, including a walking device body 1, a connecting tube 2 is inserted into the side wall of the walking device body 1, and the connecting tube 2 is connected to the adjusting handle 3 through a plug-in mechanism, and the plug-in mechanism includes a mounting rod 4 fixed to the end of the adjusting handle 3, the mounting rod 4 is plugged into the connecting tube 2, the mounting rod 4 has a slide groove 5, a sliding plate 6 is inserted into the slide groove 5, and the two side walls of the sliding plate 6 are fixed with a symmetrically distributed first arc plate 7, a second arc plate 8 and a third arc plate 9 in sequence, and the sliding plate 6 is connected to the mounting rod 4 through a moving mechanism, the mounting rod 4 has three symmetrically distributed groups of mounting grooves 10, and sliders 11 are inserted into the three groups of mounting grooves 10, and the side walls of the slider 11 are connected with a clamping mechanism.

[0025] By means of the above structure: when working, the tension of the pulley is adjusted by toggling the adjusting handle 3, so as to prevent the pulley from being too loose or too tight and causing the pulley to break. When the adjusting handle 3 is working, the first arc plate 7, the second arc plate 8 and the third arc plate 9 are respectively pressed against the slider 11. Since the thickness of the first arc plate 7, the second arc plate 8 and the third arc plate 9 increases successively, the squeezing force of the spring 1201 is successively increased, which is convenient for adjusting the tightness of the card connection to avoid looseness.

[0026] like Figure 7As shown, the clamping mechanism includes a limiting ball 1202 inserted in the installation groove 10, and the limiting ball 1202 is connected to the slider 11 through a telescopic mechanism. The telescopic mechanism includes a spring 1201 inserted in the installation groove 10, and both ends of the spring 1201 are respectively fixed on the opposite side walls of the slider 11 and the limiting ball 1202. The side wall of the connecting tube 2 is provided with three groups of symmetrically distributed limiting grooves 13, and the limiting grooves 13 are adapted to the limiting ball 1202. When the mounting rod 4 is inserted into the connecting tube 2 and reaches the limiting groove 13, the limiting ball 1202 pops out into the limiting groove 13 under the action of the telescopic mechanism to form a clamping fixation, and the spring 1201 provides elastic force to facilitate the limiting ball 1202 to be clamped in the limiting groove 13.

[0027] like Figure 4 As shown, the moving mechanism includes a threaded rod 1401 inserted in the slide groove 5, the threaded rod 1401 is screwed with the sliding plate 6, the rotation of the threaded rod 1401 is driven by a rotating mechanism, the rotating mechanism includes a turntable 1402 rotatably connected to the end of the mounting rod 4, the end of the threaded rod 1401 is fixed to the end of the turntable 1402, and the other end of the threaded rod 1401 is rotatably connected to the end of the adjusting handle 3, and the sliding plate 6 slides by rotating the threaded rod 1401, so that the first arc plate 7, the second arc plate 8 and the third arc plate 9 are respectively pressed against the slider 11, and the threaded rod 1401 is conveniently driven to rotate by rotating the turntable 1402.

[0028] How this utility works:

[0029] When in use, the mounting rod 4 is inserted into the connecting tube 2, and the limiting ball 1202 is initially retracted into the mounting groove 10 under the pressure of the spring 1201. When the mounting rod 4 is inserted into the connecting tube 2 and reaches the limiting groove 13, the limiting ball 1202 is ejected into the limiting groove 13 under the action of the spring 1201 to form a snap connection and fixation, which is convenient for quick installation and replacement of the adjusting handle 3, and at the same time, convenient for adjusting the length of the adjusting handle 3 and the connecting tube 2, which is more convenient to use;

Since the thickness of the first curved plate 7, the second curved plate 8 and the third curved plate 9 increase successively, the force of squeezing the spring 1201 increases successively, which makes it easy to adjust the tightness of the card connection and avoid looseness.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
