[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] Exemplary pedal arrangement

[0031] Figure 1 The schematic diagram of the structure of the pedal device provided by the technical solution disclosed in the utility model is exemplified. Figure 1-6It can be seen that a pedal device is provided, which includes a mounting frame 1, a lock 5, a pedal body 4 and a lock 5. The mounting frame 1 includes a cross frame 11 and a side frame 12. The cross frame 11 has two opposite ends. The two side frames 12 are arranged in a one-to-one correspondence with the opposite ends of the cross frame 11. The lock 5 is arranged at one end of the side frame 12 away from the cross frame 11. The lock 5 is suitable for detachably connecting the mounting frame 1. The pedal body 4 is arranged on the cross frame 11.

[0032] Continue to combine Figure 1 As shown, the above-mentioned cross frame 11 and side frame 12 are connected to form a U shape, or the cross frame 11 and the side frame 12 are integrally arranged to form a U shape. The cross frame 11 and the side frame 12 are both tubular structures. The pedal body 4 is arranged on the cross frame 11. One end of the side frame 12 away from the cross frame 11 extends in a direction away from the side frame 12 to form the end of the side frame 12. The lock buckle 5 is arranged at the end of the side frame 12, and the locking or unlocking of the pedal device can be achieved by the lock buckle 5. After unlocking, the installation position of the pedal device can be adjusted, thereby achieving the purpose of adjusting the height of the pedal device.

[0033] In another embodiment, if Figure 3 and Figure 4 As shown, the lock buckle 5 includes a movable connecting member 51 and a locking member 52. The movable connecting member 51 is arranged at the end of the side frame 12 away from the cross frame 11. The locking member 52 is detachably connected to the movable connecting member 51, so that the movable connecting member 51 can be in a locked state or an unlocked state.

[0034] The movable connecting member 51 can be movably connected to the connected member, so that the movable connecting member 51 can adjust the installation position in the movable state. When the movable connecting member 51 is adjusted to a suitable position, it is locked by the locking member 52 to achieve the fixation of the pedal device. The locking member 52 is detachably connected to the movable connecting member 51, which makes it easy to put the movable connecting member 51 in a locked state or an unlocked state.

[0035] In another embodiment, continue to combine Figure 4 As shown, the movable connecting member 51 is a notch ring, and the notch ring is provided with ear plates 53 on opposite sides of the notch. The locking member 52 is a fastener, and the fastener is connected to the ear plates 53, so that the notch of the notch ring is in a locked state in a contracted state, or the notch of the notch ring is in an unlocked state in an expanded state.

[0036] It can be understood that the notch collar is a tubular structure as a whole, and the interior of the notch collar is hollow to form an escape space so that the notch collar can be sleeved on the connected part. Because the notch collar is formed with a notch, the notch extends from one end of the notch collar to the other end, so that the notch collar has a certain elasticity. Each ear plate 53 can be integrally formed with one of the two opposite sides of the notch collar to ensure the structural strength. The fastener can lock the notch collar so that the notch collar is in a locked state, or loosen the fastener, or remove the fastener, the notch of the notch collar is in a naturally expanded state, and the naturally expanded state is an expanded state relative to the locked state. At this time, the notch collar can be unlocked.

[0037] Furthermore, the locking member 52 includes a locking nut 522 and a screw rod 521 . The locking nut 522 is fixed to the outer side of one of the ear plates 53 , and the screw rod 521 passes through the other ear plate 53 and is threadedly connected to the locking nut 522 .

[0038] It can be understood that the locking nut 522 can be provided on one of the ear plates 53, two locking nuts 522 can be provided and coaxially arranged, or two locking nuts 522 are provided side by side, and two screw rods 521 are provided accordingly. The locking nut 522 is welded and fixed to the ear plate 53, or it can be not connected to the ear plate 53, which is not specifically limited here. The other ear plate 53 is provided with a through hole, and the through hole can be used to pass the screw rod 521. The screw rod 521 is connected to the locking nut 522 by threads. The more threads connecting the screw rod 521 and the locking nut 522, the more locked the movable connecting member 51 is. On the contrary, the movable connecting member 51 is closer to or in an unlocked state. The structure is simple and reliable, and it is easy to achieve the locking or unlocking of the movable connecting member 51.

[0039] In another embodiment, the lock buckle 5 further includes a notch washer 54, which is fitted to the inner wall of the notch collar, and the notch of the notch washer 54 is smaller than the notch of the notch collar.

[0040] The notched washer 54 can increase the friction between the movable connecting member 51 and the connected member, so that the movable connecting member 51 can be more firmly fixed on the connected member. The notch of the notched washer 54 also extends from one end to the other end, which will not be described in detail here.

[0041] Furthermore, the pedal body 4 is rotatably connected to the cross frame 11 , so that the pedal body 4 has a first state and a second state. The first state is a use state of the pedal body 4 , and the second state is a storage state of the pedal body 4 .

[0042] Understandably, the pedal body 4 is rotatably connected to the cross frame 11, so that the state body can be rotated to the first state or the second state. When the function of the pedal device is not needed, the pedal body 4 can be folded, making the pedal device more convenient to use and expanding the application range of the pedal device.

[0043] In another embodiment, if Figure 2 and Figure 6 As shown, the pedal device further includes a support frame connected to the cross frame 11, and the pedal body 4 has a rotating body 41, which is rotatably connected to the support frame; wherein the pedal body 4 is supported on the support frame in the first state.

[0044] The support frame is a frame structure, which can be welded and fixed on the cross frame 11, and the support frame is set at an angle, which is more convenient for the rotating body 41 to be rotatably connected to the support frame. The pedal body 4 can be supported on the support frame in the first state, which can improve the structural strength of the pedal body 4.

[0045] Specifically, the support frame is provided with a round tube 21 , and the rotating body 41 is hook-shaped and rotatably connected to the round tube 21 .

[0046] It can be understood that the support frame is composed of a circular tube 21 as a whole, and the rotating body 41 is arranged in a structure-shaped manner. The circular tube 21 arranged at the end of the support frame penetrates the internal space formed by the rotating body 41, and the rotating body 41 can rotate on the outer circumference of the circular tube 21.

[0047] Furthermore, if Figure 5 As shown, a reinforcing rib 6 is provided at the bottom of the pedal body 4 . The reinforcing rib 6 is provided at the bottom of the pedal body 4 , and can play a role in increasing the structural strength of the pedal body 4 .

[0048] The utility model also provides a chair, which comprises chair legs and any one pedal device, wherein the pedal device is detachably connected to the chair legs through a lock buckle 5 of the pedal device to adjust the height of the pedal device.
