Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a portable treadmill. Background Art

[0002] With the continuous improvement of people's living standards and the increasing emphasis on health, fitness activities are becoming more and more popular among the public. Among many fitness equipment, treadmills are very popular because they can provide a convenient way to exercise by running. Traditional treadmills are usually large in size and heavy in weight, which brings many inconveniences to home use and transportation. For users with limited living space, large treadmills may take up too much indoor space, making the home environment appear crowded. Moreover, when the treadmill needs to be moved or transported, due to its heavy weight, it often requires the cooperation of multiple people to complete it, which consumes a lot of manpower and time. In addition, the operation of some traditional treadmills is also relatively complicated, and the numerous functions may not necessarily meet the actual needs of users. For many users who just want to do simple running exercises, these complicated functions have increased the difficulty and cost of use.

[0003] Most existing treadmills are cumbersome to transport, and users often need to perform some strenuous operations during the transport process, such as lifting and dragging. During this process, users can easily be injured due to improper operation, such as spraining the waist, straining muscles, etc. At the same time, if improperly operated, the treadmill itself and surrounding furniture, walls and other items may be damaged, which will not only increase maintenance costs, but may also cause damage to the home environment.

[0004] Therefore, it is urgent to provide a kind of portable treadmill to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a portable treadmill.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a lightweight treadmill, including a connecting plate, a plurality of mounting sleeves are fixedly connected to the bottom of the two connecting plates, and the inner walls of the plurality of mounting sleeves are threadedly connected to a support seat, a dust box is fixedly connected between one side of the two connecting plates, a transmission assembly is installed on the inner wall of the dust box, a baffle is fixedly connected to the top of the two connecting plates, a plurality of first bolts are threadedly connected between the two baffles and the corresponding connecting plates, a folding handle assembly is provided between one side of the outer walls of the two connecting plates, a pushing handle assembly is provided between the other side of the outer walls of the two connecting plates, and a shock absorbing assembly is installed between the inner walls of the two connecting plates.

[0007] The utility model is further configured as follows: the transmission assembly includes a driving motor installed inside the dustproof box, the output end of the driving motor is fixedly connected to a driving wheel, both ends of the inner walls of the two connecting plates are rotatably connected to rotating rods, the outer walls of the two rotating rods are fixedly connected to the transmission wheels, a belt is provided between the outer walls of the two transmission wheels, the front end of the outer wall of one of the rotating rods is fixedly connected to a driven wheel, and a leather strip is provided between the driving wheel and the driven wheel.

[0008] Through the above technical solution, the driving motor is first started, so that the driving motor drives the active wheel to rotate, and then the active wheel drives the leather strap to rotate, and then the leather strap drives the driven wheel to rotate synchronously. At the same time, the driven wheel drives one of the rotating rods to rotate, and then the rotating rod drives the corresponding transmission wheel to rotate synchronously, and then the friction between the belt and the other transmission wheel drives the other transmission wheel to rotate along the outer wall of the corresponding rotating rod, thereby achieving the transmission purpose.

[0009] The utility model is further configured as follows: the driving wheel and the driven wheel are in the same plane, and the diameter of the driving wheel is smaller than the diameter of the driven wheel.

[0010] Through the above technical solution, the smaller diameter of the driving wheel makes its rotation speed relatively faster, while the larger diameter of the driven wheel makes its rotation speed relatively slower. This combination can convert the high input speed into a lower output speed. At the same time, the arrangement on the same plane makes the installation of the transmission components easier, reduces the need for complex support structures, and reduces the installation cost and difficulty.

[0011] The utility model is further configured as follows: the folding handle assembly includes a first connecting rod fixedly connected to one side of the outer wall of the two connecting plates, the outer walls of the two first connecting rods are rotatably connected to a fixing rod, the two fixing rods and the corresponding connecting plates are threadedly connected with a second bolt, the tops of the outer walls of the two fixing rods are fixedly connected to a connecting block, one side of the outer walls of the two connecting blocks are fixedly connected to a handle, a mounting block is fixedly connected between the outer walls of the two handles, an emergency stop button and a control screen are provided on the top of the mounting block, and the opposite surfaces of the outer walls of the two connecting plates are fixedly connected to support bars.

[0012] Through the above technical solution, when in use, you only need to rotate the two fixing rods along the corresponding outer wall of the first connecting rod to a certain angle, and then fix them with two second bolts. When you need to fold, you must first remove the two second bolts, and then rotate the two fixing rods counterclockwise along the corresponding outer wall of the first connecting rod until one side of the outer wall of the fixing rod fits into the top of the support bar.

[0013] The present invention is further configured such that outer walls of the two first connecting rods are tightly fitted with inner walls of the corresponding fixing rods.

[0014] Through the above technical solution, the tightly fitting design makes the connection between the first connecting rod and the fixed rod more stable, and can withstand greater external forces without being easily loosened or deformed. During the operation of the equipment, this firm connection can ensure that the relative positions of the various components remain stable, thereby improving the reliability of the entire structure.

[0015] The present invention is further configured such that the sizes of the two support bars are matched with the corresponding first connecting rods.

[0016] Through the above technical solution, matching means that the support bar can fit tightly with the first connecting rod, providing it with uniform and stable support force. During the operation of the equipment, the first connecting rod may be subjected to various external forces and loads, and the matching support bar can effectively disperse these forces, preventing the connecting rod from bending, deformation or breaking, thereby ensuring the stability of the entire structure.

[0017] The utility model is further configured as follows: the pushing handle assembly includes a connecting piece fixedly connected to the two connecting plates and one side of the baffle, the two connecting pieces are fixedly connected to a connecting sleeve, a fixing hole is opened between the two connecting sleeves, a fixing bolt is slidably connected to the inner wall of the fixing hole, and a nut is threadedly connected to the other end of the fixing bolt, the inner wall of the two connecting sleeves are slidably connected to a second connecting rod, and a push handle is fixedly connected between the tops of the two second connecting rods.

[0018] Through the above technical solution, when it is necessary to move, first remove the multiple support seats, then replace them with universal wheels, then slide the two second connecting rods to the corresponding inner walls of the connecting sleeves, and fix them with fixing bolts, and finally push the handle.

[0019] The utility model is further configured as follows: the outer walls of the two second connecting rods are tightly fitted with the inner walls of the corresponding connecting sleeves, and the push handle is provided with rounded corners.

[0020] Through the above technical solution, the contact area between the second connecting rod and the connecting sleeve is increased, and it can withstand greater external forces without being easily loosened or separated. During the use of the handling equipment, whether it is subjected to push-pull force or force in other directions, this firm connection can ensure the stability of the overall structure.

[0021] The utility model is further configured as follows: the shock absorbing assembly includes a mounting plate fixedly connected to the inner walls of the two connecting plates, a plurality of shock absorbing blocks are fixedly connected to the tops of the two mounting plates, and a support plate is installed between the two groups of shock absorbing blocks.

[0022] Through the above technical solution, when the belt is squeezed downward, the squeezing force will be transmitted to the upper surface of the mounting plate, causing the mounting plate to move downward. The mounting plate will then transmit the downward force to multiple shock-absorbing blocks, thereby achieving the purpose of shock absorption.

[0023] The utility model is further configured as follows: the distance between each two shock-absorbing blocks is equal, and both are made of rubber material.

[0024] Through the above technical solution, since the load borne by each shock-absorbing block is relatively balanced, their performance in the shock absorption process will be more consistent. This can ensure that the equipment can obtain a relatively stable shock absorption effect when it is vibrated at different positions, reducing shaking or instability caused by uneven shock absorption.

[0025] The beneficial effects of the utility model are as follows:

[0026] 1. The utility model provides a foldable handle assembly. The folded handle does not take up additional space, making it easier to store the treadmill in a corner, closet or other small space.

[0027] 2. The utility model can help users better control the moving direction of the treadmill by setting a push handle assembly. During the transportation process, the user can guide the treadmill in the forward direction by adjusting the direction of the handle to avoid collision or jamming with surrounding objects, which makes the transportation process smoother and reduces the trouble and damage risk caused by loss of control of direction.
