Abstract
Description
Technical Field
[0001] This utility model relates to the field of treadmill technology, and in particular to a treadmill lifting and folding switching device. Background Technology
[0002] Currently, some treadmills have designs where the work platform is adjustable in elevation, meaning they have a lifting structure that raises the front of the work platform to create a slope, allowing users to simulate climbing.
[0003] Treadmill workbenches typically extend a considerable distance along the ground, thus taking up a significant amount of space. Some modern treadmills now feature a foldable workbench to save space when not in use.
[0004] However, treadmills that simultaneously incorporate both a lifting and folding platform structure are typically quite complex.
[0005] How to achieve the tilt angle adjustment of the treadmill workbench through a simple structure, as well as the folding problem, remains to be solved. Utility Model Content
[0006] The purpose of this utility model is to provide a treadmill lifting and folding switching device, and to solve the technical problem of adjusting the tilt angle of the treadmill workbench and folding it through a simple structure.
[0007] To achieve the above objectives, the solution of this utility model is: a treadmill lifting and folding switching device, including a worktable, a base, a support, a telescopic rod, and a hook structure;
[0008] The front-to-back length of the base is less than that of the worktable. The base is located below the front of the worktable and is designed to rest on the ground. The rear of the worktable can also rest on the ground.
[0009] The bottom end of the bracket is pivotally connected to the base so that the top end of the bracket can swing back and forth. The top end of the bracket tilts backward and is pivotally connected to the front half of the worktable.
[0010] One end of the telescopic rod is hinged to the base, and the other end is hinged to the bracket, so that the top of the bracket can be rotated by the extension and retraction of the telescopic rod.
[0011] The hook structure allows the front end of the worktable, located at the front of the pivot point between the support and the worktable, to be hooked and released onto the base or support, thereby restricting the front end of the worktable from lifting after hooking.
[0012] Furthermore, the bottom end of the telescopic rod is pivotally connected to the base, and the pivot point with the base is located behind the pivot point between the support and the base, so that the top end of the telescopic rod can swing back and forth. The top end of the telescopic rod is pivotally connected to the support, and the pivot point with the support is higher than the pivot point between the support and the worktable.
[0013] Furthermore, the hook structure includes a swing plate, the top of which is pivotally connected to the worktable so that the bottom of the swing plate can swing left and right. The bottom of the swing plate has a left and right extending pin, and the base has left and right extending pin holes. The axis of the rotating shaft that pivotally connects the bracket to the base passes through the pin holes. The swing plate swings so that it can drive the pin to insert and retract from the pin holes.
[0014] Furthermore, it also includes an electric pushing device and an elastic element. The electric pushing device is installed on the worktable and is used to electrically push the swing plate, causing the swing plate to swing toward the pin hole, thereby driving the pin to insert into the pin hole. The elastic element is connected between the swing plate and the worktable and elastically pulls the swing plate away from the pin hole.
[0015] Furthermore, the electric pushing device includes a motor and a swing arm. The motor is fixed on the worktable, and the swing arm is fixed on the motor shaft. The end of the swing arm protrudes radially from the motor shaft, and the swing plate is located on the moving path of the end of the swing arm. The swing arm is driven to rotate by the motor, so that the end of the swing arm pushes the swing plate toward the pin hole.
[0016] Furthermore, the end of the pin has a radially protruding retaining edge. After the pin is inserted into the pin hole, the retaining edge can abut against the outer edge of the pin hole opposite to the swing plate to prevent the pin from exiting the pin hole.
[0017] Furthermore, the pin hole includes an insertion section and a locking section. The cross-sectional size of the insertion section is large enough for the pin to pass through. The locking section is connected above the insertion section. The cross-sectional size of the locking section is smaller than that of the retaining edge, so that after the pin enters the locking section from the insertion section, the retaining edge restricts the pin from exiting the pin hole.
[0018] Furthermore, the elastic element is a spring.
[0019] Furthermore, running belts are arranged at the front and back of the workbench.
[0020] After adopting the above solution, the beneficial effects of this utility model are as follows:
[0021] (1) Since the bottom end of the support is pivotally connected to the base, the top end of the support can swing back and forth. The top end of the support tilts backward and is pivotally connected to the front half of the worktable. One end of the telescopic rod is hinged to the base, and the other end is hinged to the support. The telescopic rod can be extended to drive the top end of the support to swing. Therefore, when the telescopic rod is extended, it will drive the rear end of the support to swing upward, and when it is shortened, it will drive the rear end of the support to swing downward. Thus, when the hook structure releases the front part of the worktable from the base or support, the front part of the worktable can move up and down with the rear end of the support, while the rear part of the worktable falls to the ground due to gravity, thereby realizing the adjustment of the tilt angle of the worktable. When the hook structure hooks the front part of the worktable to the base or support, the lifting of the front part of the worktable will be restricted, so that the rear part of the worktable moves up and down with the rear end of the support, thereby enabling the rear part of the worktable to be lifted and the worktable to be erected above the base, thus realizing the folding.
[0022] (2) The hook structure includes a swing plate. The top of the swing plate is pivotally connected to the worktable so that the bottom of the swing plate can swing left and right. The bottom of the swing plate has a pin extending left and right. The base has pin holes extending left and right. The axis of the rotating shaft pivotally connected to the base passes through the pin hole. The swing plate swings so that the pin can be inserted into and out of the pin hole. After the pin is inserted into the pin hole, the front end of the worktable is restricted and cannot be lifted up. At this time, the mode of driving the running table to fold is switched. After the pin is removed from the pin hole, the front end of the worktable is released and can be lifted up. At this time, the mode of driving the running table to adjust the tilt angle is switched.
[0023] (3) The swing plate is pushed by the electric pusher to swing towards the pin hole, thereby driving the pin to insert into the pin hole. The elastic element is connected between the swing plate and the worktable, and the swing plate is pulled away from the pin hole. After the electric pusher releases the swing plate, the pin can automatically exit the pin hole. The simple structure realizes the automatic switching of the tilt angle adjustment and folding modes of the worktable. Attached Figure Description

[0037] A treadmill lifting and folding switching device, such as Figure 1-10As shown, the system includes a workbench 1, a base 2, a support 3, a telescopic rod 4, and a hook structure. The front-to-back length of the base 2 is less than that of the workbench 1. The base 2 is located below the front of the workbench 1 and is designed to rest on the ground. The rear of the workbench 1 can rest on the ground. Running belts 15 are installed on the front and back of the workbench 1 for users to stand on and run. The bottom end of the support 3 is pivotally connected to the base 2, allowing the top end of the support 3 to swing back and forth. The top end of the support 3 tilts backward and is pivotally connected to the front half of the workbench 1 via a pivot extending to the left and right. One end of the telescopic rod 4 is hinged to the base 2, and the other end is hinged to the support 3. The specific structure is not limited, as long as the telescopic rod 4 can cause the top end of the support 3 to swing through its extension and retraction. Specifically, in this embodiment, the bottom end of the telescopic rod 4 is pivotally connected to the base 2, and the pivot point with the base 2 is located behind the pivot point between the support 3 and the base 2, so that the top end of the telescopic rod 4 can swing back and forth. The top end of the telescopic rod 4 is connected to the base 2 via a pivot extending to the left and right. The left and right extending pivots are pivotally connected to the support 3, and the pivot point with the support 3 is higher than the pivot point between the support 3 and the worktable 1. Therefore, when the telescopic rod 4 extends, it will push against the rear end of the support 3 and lift it, thereby pushing against the front end of the worktable 1 and lifting it. The rear end of the worktable 1 is kept on the ground by gravity. The height of the front end of the worktable 1 can be adjusted by extending and retracting the telescopic rod 4, so that the user can simulate different climbing angles. The hook structure can hook and release the front end of the worktable 1, located in front of the pivot point between the support 3 and the worktable 1, onto the base 2 or the support 3. After hooking, the front end of the worktable 1 is restricted from lifting. At this time, the rear end of the worktable 1 will rise and fall with the rear end of the support 3, which can realize the worktable 1 being erected above the base 2 for folding. Specifically, in this embodiment, the hook structure is hooked onto the base 2. The structure hooked onto the support 3 is not shown in the figure, but it is the same as the structure hooked onto the base 2 and will not be described in detail.
[0038] The preferred hook structure includes a swing plate 5, specifically as follows: pin holes 8 extend left and right on the base 2, and the axis of the pivot shaft that pivotally connects the support 3 to the base 2 passes through the pin holes 8. Specifically, a vertical plate 16 is provided at the front end of the base 2, and the pin holes 8 are provided on the vertical plate 16, extending left and right through the vertical plate 16. The top of the swing plate 5 is pivotally connected to the worktable 1 so that the bottom end of the swing plate 5 can swing left and right. A left and right extending pin 9 is formed at the bottom end of the swing plate 5. When the front end of the worktable 1 is lowered to a predetermined position, the swing plate 5 swings toward the pin holes 8, which will drive the pin 9 to insert into the pin holes 8. At this time, the front end of the worktable 1 cannot be raised significantly. When the telescopic rod 4 extends and drives the rear end of the support 3 to rise, the rear part of the worktable 1 will be raised off the ground simultaneously. Since the front and rear length of the base 2 is small, the space occupied by the treadmill in the front and rear direction will be greatly reduced, realizing folding.
[0039] The electric pushing device 6 is installed on the worktable 1. It can be any existing structure that can be used to electrically push the swing plate 5 so that the swing plate 5 swings toward the pin hole 8. The preferred structure used in this embodiment is given later. The electric pushing device 6 can then electrically drive the pin 9 to insert into the pin hole 8. The elastic element 7 is connected between the swing plate 5 and the worktable 1. Specifically, in this embodiment, the elastic element 7 is a spring. When the electric pushing device 6 releases the swing plate 5, the elastic element 7 elastically pulls the swing plate 5 away from the pin hole 8, and then switches back to the mode in which the telescopic rod 4 extends and retracts to drive the front end of the worktable 1 to lift or lower.
[0040] To keep the structure of the electric pushing device 6 as simple as possible, the preferred electric pushing device 6 includes a motor 10 and a swing arm 11. The motor 10 is fixed on the worktable 1. Specifically, in this embodiment, the rotating shaft of the motor 10 is perpendicular to the swing direction of the swing plate 5, but this is not a limitation. The swing arm 11 is fixed on the rotating shaft of the motor 10, and the end of the swing arm 11 protrudes radially from the rotating shaft of the motor 10. The swing plate 5 is located on the moving path of the end of the swing arm 11. By driving the swing arm 11 to rotate through the motor 10, the end of the swing arm 11 can abut against the swing plate 5 and push the swing plate 5 to swing toward the pin hole 8. When the motor 10 rotates in the opposite direction, the end of the swing arm 11 will leave the swing plate 5 and release the swing plate 5.
[0041] In a preferred embodiment, the end of the pin 9 has a radially protruding retaining edge 12. The pin hole 8 includes an insertion section 13 and a locking section 14. The cross-sectional size of the insertion section 13 is large enough for the pin 9 to pass through. The locking section 14 is connected above the insertion section 13, and its cross-sectional size is smaller than that of the retaining edge 12. This allows the retaining edge 12 to abut against the outer edge of the end of the pin hole 8 opposite to the swing plate 5 after the pin 9 enters the locking section 14 from the insertion section 13. The retaining edge 12 restricts the pin 9 from exiting the pin hole 8, thus lowering the front end of the worktable 1 to a certain height during switching. At this height, when the swing plate 5 swings toward the pin hole 5, the pin 9 is aligned with the insertion section 13. At this time, the pin 9 can pass through the pin hole 8. Then the telescopic rod 4 extends, which will drive the front end of the worktable 1 to lift a certain height, so that the pin 9 enters the locking section 14. At this time, even if the electric pushing device 6 releases the swing plate 5, it will not cause the pin 9 to exit the pin hole 8. Only when the telescopic rod 4 shortens and the pin 9 re-enters the insertion section 13 can the swing plate 5 be swung away from the pin hole 8 under the pull of the elastic element 7, thus driving the pin 9 out of the pin hole 8, ensuring safety during use.
[0042] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
