Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, and in particular to a treadmill with a folding function. Background Technology

[0002] Because treadmills can be used at home, are not limited by weather or time, and allow for exercise anytime, they have gained widespread acceptance among fitness enthusiasts. Some elderly people or athletes use treadmills to improve their cardiovascular function and physical fitness through brisk or moderate-speed walking.

[0003] Walking machines do not have handrails, have a small footprint, and are convenient to store and use. However, the handrails of existing treadmills cannot be folded, so the treadmill cannot be folded up and used as a walking machine, which reduces the treadmill's versatility. Utility Model Content

[0004] To address the technical problem that the handrails in existing treadmills cannot be folded, this invention provides a treadmill with a folding function.

[0005] The treadmill with a folding function provided by this utility model adopts the following technical solution:

[0006] A treadmill with a folding function includes a frame and a running belt rotatably mounted on the frame. Columns are foldably mounted at the ends of the left and right sides of the frame. Handrail tubes are foldably mounted at the ends of the columns furthest from the frame. A column side box is fixedly installed at the end of the column furthest from the frame. A column pivot plate is fixedly installed inside the column side box. A handrail pivot plate is fixedly installed at the end of the handrail tube. The handrail pivot plate and the column pivot plate are rotatably connected. A folding mechanism for fixing the position of the handrail tube is provided on the handrail tube.

[0007] The folding mechanism includes a folding switch and a switch rod fixedly disposed on the side of the folding switch. A handrail side box is fixedly disposed on the outside of the handrail pivot plate. An arc-shaped groove is located on the outside of the handrail side box. The folding switch is rotatably connected inside the arc-shaped groove. The switch rod on the side of the folding switch passes through the side wall of the handrail tube and the handrail pivot plate and extends to the side of the column pivot plate. Rotating the folding switch causes the bottom end of the switch rod to separate from or engage with the side wall of the column pivot plate, thereby folding and fixing the handrail tube.

[0008] Furthermore, a sliding pin is provided on the side of the column pivot plate, and a sliding groove is provided on the side of the handrail pivot plate. The sliding pin in the column pivot plate is embedded in the sliding groove. When the handrail tube is rotated and folded upward, the sliding pin slides in the sliding groove. The sliding groove limits the folding position of the handrail tube, so that the handrail tube is folded in the horizontal position of the column.

[0009] Furthermore, a semi-circular block is provided at one end of the switch rod near the column pivot plate, and a first arc-shaped groove and a second arc-shaped groove are provided on the side of the column pivot plate. Rotating the folding switch causes the arc-shaped surface of the semi-circular block to embed into the first arc-shaped groove in the column pivot plate. The arc-shaped surface of the semi-circular block and the first arc-shaped groove in the column pivot plate engage with each other, fixing the position of the handrail tube. Rotating the folding switch in the opposite direction causes the arc-shaped surface of the semi-circular block to move out of the first arc-shaped groove in the column pivot plate. At this time, the handrail tube is in an active state. After folding the handrail tube upward, rotating the folding switch causes the arc-shaped surface of the semi-circular block to embed into the second arc-shaped groove in the column pivot plate. The arc-shaped surface of the semi-circular block and the second arc-shaped groove in the column pivot plate engage with each other, fixing the folded position of the handrail tube.

[0010] Furthermore, the surface of the arc-shaped groove located in the armrest side box has an elastic convex shape.

[0011] Furthermore, a limiting protrusion is provided on the side of the arc-shaped groove near the elastic convex circle, and a fixing groove is provided on the side of the folding switch. When the folding switch is rotated upward, the upper part of the folding switch is stopped by the limiting protrusion. During the rotation, the folding switch moves into the fixing groove in the folding switch under the elastic force of the elastic convex circle, thereby fixing the rotation position of the folding switch.

[0012] Furthermore, the bottom of the column is rotatably connected to the side of the frame, and a knob is slidably connected at the bottom of the column. A fixing sleeve is provided at the position corresponding to the knob on the side of the frame, so that the knob is screwed into the fixing sleeve to fix the position of the column.

[0013] Furthermore, a control box is located at the center of the handrail tube, and a display is detachably installed on the side of the control box.

[0014] Furthermore, a protrusion is provided on the side of the control box, and a mounting groove that mates with the protrusion is provided on the side of the display. The opening size of the mounting groove gradually decreases, thereby tightly engaging the protrusion.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a folding mechanism, allows the folding switch in the folding mechanism to move downwards, causing the elastic convex circle to move out of the fixed groove in the folding switch. At this time, the arc-shaped surface in the semi-circular block moves out of the first arc-shaped groove in the column pivot plate, making the handrail tube in a movable state. The handrail tube is then rotated upwards and folded so that the handrail tube and the column are on the same horizontal plane. Subsequently, the folding switch is rotated so that the arc-shaped surface in the semi-circular block is embedded into the second arc-shaped groove in the column pivot plate, fixing the folding position of the handrail tube. At the same time, the position of the folding switch is fixed by the elastic convex circle, and the knob at the bottom of the column is rotated out of the fixed sleeve, making the column in a movable state. The column is rotated towards the frame, folding the column and handrail tube to the side of the running belt, thereby folding the treadmill into a walking machine for users to use for brisk walking, increasing the treadmill's versatility.

[0017] 2. By providing a protrusion on the side of the control box and a mounting groove on the side of the display that mates with the protrusion, the display and control box can be detachably connected. When the column and handrail tube are folded downwards, the display can be pulled upwards from the side of the control box, effectively preventing the display from colliding with the ground after the column and handrail tube are folded downwards.

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0031] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 The image shows a treadmill with a folding function.

[0032] The first embodiment of this utility model, referred to... Figures 1-7As shown, a treadmill with a folding function is disclosed, including a frame 1 and a running belt 2 rotatably mounted on the frame 1. Columns 3 are respectively provided at the ends of the left and right sides of the frame 1. Handrail tubes 4 are foldably provided at the ends of the columns 3 on the side away from the frame 1, so that users can hold the handrail tubes 4 when running. Preferably, a column side box 31 is bolted to the end of the column 3 on the side away from the frame 1. A column pivot plate 81 is fixedly installed inside the column side box 31. A sliding pin 811 is provided on the side of the column pivot plate 81 protruding outward. A handrail pivot plate 82 is fixedly installed at the end of the handrail tube 4. The handrail pivot plate 82 and the column pivot plate 81 are rotatably connected. A sliding groove 821 is provided on the side of the handrail pivot plate 82. The sliding pin 811 in the column pivot plate 81 is embedded in the sliding groove 821. When the handrail tube 4 is rotated and folded upward, the sliding pin 811 slides in the sliding groove 821. The sliding groove 821 limits the folding position of the handrail tube 4, so that the handrail tube 4 is folded in the horizontal position of the column 3. A folding mechanism 5 is provided on the handrail tube 4 to fix the position of the handrail tube 4. The folding mechanism 5 includes a folding switch 51 and a switch rod 52 fixedly disposed on the side of the folding switch 51. A handrail side box 41 is fixedly disposed on the outside of the handrail pivot plate 82. An arc-shaped groove 411 is located on the outside of the handrail side box 41. The folding switch 51 is rotatably connected inside the arc-shaped groove 411. The switch rod 52 on the side of the folding switch 51 passes through the side wall of the handrail tube 4 and the handrail pivot plate 82 and extends to the side of the column pivot plate 81. A semi-circular block 521 is provided at one end of the switch rod 52 near the column pivot plate 81. A first arc-shaped groove 812 and a second arc-shaped groove 813 are provided on the side of the column pivot plate 81. The folding mechanism 5 is rotatable. Switch 51 causes the arc-shaped surface of the semicircular block 521 to embed into the first arc-shaped groove 812 in the column pivot plate 81. The arc-shaped surface of the semicircular block 521 and the first arc-shaped groove 812 in the column pivot plate 81 engage with each other, fixing the position of the handrail tube 4. Reverse rotation of the folding switch 51 causes the arc-shaped surface of the semicircular block 521 to move out of the first arc-shaped groove 812 in the column pivot plate 81. At this time, the handrail tube 4 is in an active state. After folding the handrail tube 4 upward, rotate the folding switch 51 to embed the arc-shaped surface of the semicircular block 521 into the second arc-shaped groove 813 in the column pivot plate 81. The arc-shaped surface of the semicircular block 521 and the second arc-shaped groove 813 in the column pivot plate 81 engage with each other, fixing the folded position of the handrail tube 4.

[0033] Reference Figure 3 and Figure 4As shown, the surface of the arc-shaped groove 411 in the armrest side box 41 has an elastic convex circle 412. A limiting protrusion 413 is provided on the side of the arc-shaped groove 411 near the elastic convex circle 412. A fixing groove 511 is provided on the side of the folding switch 51. When the folding switch 51 is rotated upward, the upper part of the folding switch 51 is stopped by the limiting protrusion 413. During the rotation, under the elastic force of the elastic convex circle 412, it moves into the fixing groove 511 in the folding switch 51, thus fixing the rotation position of the folding switch 51.

[0034] Reference Figures 8-9 As shown, the bottom of the column 3 is rotatably connected to the side of the frame 1. A knob 11 is slidably connected to the bottom of the column 3. A fixing sleeve 12 is provided on the side of the frame 1 at a position corresponding to the knob 11, so that the knob 11 is screwed into the fixing sleeve 12 to fix the position of the column 3.

[0035] When walking with the handrail tube 4 and upright column 3 folded to the side of the frame 1, the folding switch 51 is folded downwards, causing the elastic convex circle 412 to move out of the fixing groove 511 in the folding switch 51. At this time, the arc-shaped surface of the semi-circular block 521 moves out of the first arc-shaped groove 812 in the upright rotating plate 81, putting the handrail tube 4 in an active state. The handrail tube 4 is then rotated upwards to make the handrail tube 4 and upright column 3 on the same horizontal plane. Then, the folding switch 51 is rotated to make the semi-circular block 521... The arc-shaped surface of 21 is embedded into the second arc-shaped groove 813 in the column pivot plate 81 to fix the folding position of the handrail tube 4. At the same time, the position of the folding switch 51 is fixed by the elastic convex circle 412. The knob 11 at the bottom of the column 3 is rotated out from the fixed sleeve 12, so that the column 3 is in an active state. The column 3 is rotated towards the frame 1, and the column 3 and handrail tube 4 are folded on the side of the running belt 2, so that the treadmill can be folded into a walking machine for users to exercise.

[0036] The second embodiment of this utility model is described below. Figure 10 and Figure 11 As shown, a control box 6 is located at the center of the handrail tube 4, and a display 7 is detachably mounted on the side of the control box 6. Preferably, a protrusion 61 is provided on the side of the control box 6, and a mounting groove that mates with the protrusion 61 is provided on the side of the display 7. The opening size of the mounting groove gradually decreases, thereby tightly engaging the protrusion 61.

[0037] When the column 3 and handrail tube 4 are folded downwards, the display 7 is pulled upwards from the side of the control box 6, which effectively prevents the display 7 from colliding with the ground after the column 3 and handrail tube 4 are folded downwards.
