Technical Field

[0001] The utility model belongs to the technical field of treadmills, and particularly relates to an installation-free foldable treadmill. Background Art

[0002] A treadmill is a common piece of fitness equipment that simulates the outdoor running environment, allowing users to run or briskly walk indoors. The benefits of using a treadmill include being unaffected by the weather and having a built-in display that can show your exercise data, such as speed, time, distance, and calorie consumption.

[0003] When setting up existing treadmills, after confirming the installation location, the components need to be assembled. As a result, in scenarios where the treadmill is used extensively, an extremely long installation time is required. In addition, the emergency brake switches provided on existing treadmills are mostly external buttons or clips that are clamped on the user's body. The brake switch is connected to the brake switch by a thin cord, and the brake switch is triggered by pressing the button or pulling the thin cord. In the event of an emergency, if the user is conscious but cannot press or pull the thin cord in time, the treadmill cannot be stopped, causing the user to fall and be injured. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 7 As shown, a foldable treadmill that does not require installation in this embodiment includes a base 1, with gear sets 2 installed on both ends of the base 1 for fixed-axis rotation. A chain 3 is engaged with the periphery of the gear set 2, and a runway cloth 4 is installed on the outer side of the chain 3. The top of the base 1 is provided with an opening that matches the runway cloth 4. There are two groups of gear sets 2, and each group of gear sets 2 is composed of two gears located on both sides of the base 1. A bearing platform 5 is installed inside the base 1. The top of the bearing platform 5 is parallel to the top surface of the base 1 and a buffer pad is installed on the top. A spring shock absorber is installed inside the bearing platform 5, and a power facility connected to the gear set 2 and a matching electronic control device are also provided inside the base 1.

[0026] One end of the base 1 is equipped with a mounting box 6, and the side wall of the mounting box 6 is equipped with an insert 7. A latch 8 is slidably installed inside the insert 7. A plug 9 is installed at one end of the latch 8 located inside the mounting box 6. A first spring 10 is provided on the end of the outer surface of the latch 8 close to the plug 9. A limit plate 11 is installed at the center of the mounting box 6. Two slots are provided on the side of the limit plate 11 that are angled with each other and match the plug 9. Figure 6 as well as Figure 7 As shown, the angles between the slots on the limit plate 11 are set to meet the requirements of the guard bar 12 for rotation and folding, thereby cooperating with the use of the latch 8 to allow the guard bar 12 to be converted from the use state to the folded state. The size of the plug 9 is the same as that of the insert 7. The setting position of the first spring 10 on the latch 8 is located between the insert 7 and the plug 9. The first spring 10 is restricted between the plug 9 and the insert 7. When the latch 8 is pulled, the plug 9 can rebound and reset with the help of the elastic force of the first spring 10, and the number of the latch 8 and the plug 9 is not less than two to ensure stability.

[0027] The limit plate 11 is installed with a guard rod 12 through a connecting shaft extending to the outside of the mounting box 6. A mounting rod 13 is installed on the top of the side of the guard rod 12. A display screen 14 is installed in the middle of the outer surface of the mounting rod 13. A mounting block 15 is installed on the outer surface of the mounting rod 13. Figure 1 and Figure 5It can be seen that the base shape of the display screen 14 and the shape of the mounting block 15 are both annular and match the shape of the guardrail 12. Therefore, by opening a threaded hole on the guardrail 12 and using bolts, the display screen 14 and the mounting block 15 can be folded by disassembling the bolts and reassembling them. This also satisfies the stability of the display screen 14 and the mounting block 15 on the guardrail 12 when the treadmill is working properly. There are two mounting blocks 15 and they are symmetrically distributed on the mounting rod 13 with the display screen 14 as the symmetrical point. A connecting tube 16 is installed on the side of the mounting block 15 facing the runway cloth 4. A sleeve is installed inside the connecting tube 16. The outer surface of the slide rod 20 has a limit tube and a slide groove on the side of the limit tube. The side of the slide rod 20 is installed with a slider that is slidably connected to the slide groove on the limit tube set inside the connecting tube 16. An emergency stop switch 17 is installed at one end of the connecting tube 16. An electromagnet 18 is installed at the end of the connecting tube 16 away from the emergency stop switch 17. A second spring 19 is sleeved on one end of the electromagnet 18. A slide rod 20 is installed on one end of the second spring 19. A magnet is installed on the end of the slide rod 20 close to the electromagnet 18, and the magnetic pole of the magnet close to the end of the electromagnet 18 is in the same direction as the magnetic pole of the electromagnet 18. When the micro switch 2 2 is triggered, the electromagnet 18 is energized and generates magnetic force, and then by setting the direction of the magnet and utilizing the principle of like poles repelling each other, the slide bar 20 is moved, and a striker 21 is installed at one end of the slide bar 20. The movement of the slide bar 20 causes the striker 21 to strike the emergency brake switch to achieve braking. After the electromagnet 18 is powered off, the slide bar 20 is reset by the elastic force of the second spring 19. A micro switch 22 is installed inside the connecting tube 16. The number of micro switches 22 is not less than two and is evenly distributed inside the connecting tube 16. A handle 23 is installed at one end of the connecting tube 16. One end of the handle 23 is installed. Equipped with rubber columns 24, the number of which is not less than two and which are parallel to the micro switch 22. By setting the number of micro switches 22 and the arrangement of the rubber columns 24, since the rubber columns 24 are parallel to the micro switch 22 and use rubber columns 24 with a thicker diameter, when the rubber columns 24 swing, they can hit the micro switch 22, thereby triggering the micro switch 22 and starting the electromagnet 18. The subsequent braking process is carried out by the magnetic force of the electromagnet 18, and thus the treadmill can retain the existing conventional brake switch, and additionally form a double insurance by setting components inside the connecting tube 16 to protect the safety of the user.

[0028] The working principle of this embodiment is as follows. When in use, due to the installation method of the guard bar 12, the guard bar 12 and the base 1 are installed as one piece. Then, when arranging the treadmill, after placing the base 1 at a designated location, the pin 8 is pulled outward to disengage the plug 9 from the groove provided on the limit plate 11. Then, the guard bar 12 is rotated. After the guard bar 12 is rotated to the correct position, the pin 8 re-enters the groove provided on the side of the limit plate 11 under the action of the elastic force of the first spring 10, thereby fixing the position of the guard bar 12 and quickly completing the installation.

[0029] When the treadmill is being used, the user is unable to keep up with the speed of the treadmill due to exhaustion and is about to fall. At this time, the user fails to touch the external emergency brake device in time. For the sake of self-protection, the user subconsciously grabs the handle 23, and the handle 23 vibrates due to the instantaneous grip. The vibration is transmitted to the rubber column 24 by the handle 23, and the rubber column 24 swings due to the vibration, so that the rubber touches the micro switch 22 during the swinging process. When the micro switch 22 is touched, the electromagnet 18 is energized, and the slide bar 20 is pushed by magnetic force, causing the striker 21 to hit the emergency stop switch 17, achieving an emergency stop.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
