It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, without being stated to the contrary, the use of directional words such as "front and rear" refers to the front and rear as defined in the normal use of the folding treadmill of the present disclosure, and "front" refers to the direction the user is facing when using the folding treadmill; "rear" refers to the direction the user is facing back when using the folding treadmill; in particular, reference may be made to fig. 1; the foldable treadmill using the directional words such as "upper, lower, left and right" is defined as upper, lower, left and right in the normal use state, and specifically, can also refer to fig. 1; terms such as "first, second, third" are used merely to distinguish one element from another and are not sequential or significant.

As shown in fig. 1 to 6, the present disclosure provides a running table locking mechanism for a folding type treadmill, which includes a locking pin 30 for being inserted between a first frame 10 and a second frame (not shown)) to lock a relative rotation therebetween, a pulling wire 40 extended in the same direction as the locking pin 30 for pulling the locking pin 30 to be unlocked, and a link assembly 100 connected between the pulling wire 40 and the locking pin 30.

Wherein, the connecting rod assembly 100 comprises a first connecting rod 1 and a second connecting rod 2, the first connecting rod 1 is rotatably connected to the front end of the pull wire 40; the second link 2 is rotatably connected to the front end of the first link 1 and is rotatably connected to the first frame 10 or the second frame via a first rotating shaft (not shown), and the second link 2 is formed as a lever having a rear arm length larger than a front arm length with the first rotating shaft as a fulcrum.

Further, the connecting rod assembly 100 is configured to: when pulled backward by the pull wire 40, the rear end of the first link 1 moves backward, the front end of the first link 1 rotates and drives the second link 2 to rotate, and the front end of the second link 2 drives the lock pin 30 to move backward so that the first frame 10 and the second frame can rotate relatively.

In the above technical solution, first, the link assembly 100 is disposed between the wire 40 and the lock pin 30, and the link assembly 100 can transmit a force pulling the wire 40 backward to the lock pin 30 and drive the lock pin 30 to move backward, so as to release the lock of the lock pin 30 to the first frame 10 and the second frame, so that the first frame 10 and the second frame can rotate relatively, and thus the folding operation of the first frame 10 and the second frame can be realized; secondly, the second link 2 of the link assembly 100 is configured as a lever having a rear arm length greater than a front arm length with the first pivot as a fulcrum, and the lock pin 30 can be pulled to unlock by applying a small force by using the lever principle, thereby improving the convenience of the operator pulling the pull wire 40. Moreover, by arranging the first connecting rod 1 between the second connecting rod 2 and the pull wire 40, the redundant stroke (i.e. the stroke in the non-front-back direction) of the second connecting rod 2 can be converted into the relative contraction of the first connecting rod 1 and the second connecting rod 2, the movement stroke of the pull wire 40 is shortened, the operation of an operator is facilitated, the unlocking operation of the treadmill locking mechanism by the operator is facilitated, and the subsequent folding operation of the folding treadmill is facilitated.

Referring to fig. 2, 4 and 6, the link assembly 100 further includes a third link 3 connected between a front end of the second link 2 and a rear end of the lock pin 30, the third link 3 having a slide groove 31 extending obliquely to the front-rear direction, the front end of the second link 2 being fixed with a boss 22 slidable in the slide groove 31, the link assembly 100 being configured such that: when pulled backward by the wire 40, the bump 22 slides along the slide groove 31 and pushes the third link 3 to move backward to drive the lock pin 30 to move backward.

In this embodiment, when the pulling wire 40 is pulled backward, the first link 1 moves backward and drives the second link 2 to rotate around the first rotation axis, the protrusion 22 on the front arm of the second link 2 slides in the sliding slot 31 inclined in the front-rear direction on the third link 3, and applies a backward movement force to the third link 3 to drive the lock pin 30 to move backward, thereby releasing the rotation restriction of the first frame 10 and the second frame. Through setting up this third connecting rod 3 and setting up the spout 31 that extends in the fore-and-aft direction of slope on this third connecting rod 3 to can guarantee when protruding piece 22 on the second connecting rod 2 slides in this spout 31, can exert backward power to third connecting rod 3, and then drive lockpin 30 unblock. Simple structure and drive are stable. However, the present disclosure is not limited to the specific structural design of the connecting rod assembly 100, and it is sufficient that a rearward movement force can be applied to the lock pin 30.

Alternatively, the third link 3 comprises a first portion 32 and a second portion 33 connected to each other in an inflected shape, the first portion 32 extending in a horizontal direction, the second portion 33 extending in a vertical direction, the above-mentioned slide groove 31 being provided on the first portion 32, and the second portion 33 being adapted to be connected to the lock pin 30. The second portion 33 may be fixedly connected to the locking pin 30 or rotatably connected to the locking pin 30, which is not limited in this disclosure.

Alternatively, referring to fig. 4 and 6, the first link 1, the second link 2 and the slide groove 31 are formed in a zigzag shape, and when the link assembly 100 is pulled backward by the wire 40, the protrusion 22 pushes a groove wall of the slide groove 31 close to the first link 1, thereby applying a backward force to at least the third link 3 to move the third link 3 backward. In addition, the zigzag design of the first link 1, the second link 2, and the slide groove 31 can reduce the arrangement of the link assembly 100 in the front-rear direction and reduce the use of the arrangement space.

In one embodiment, referring to fig. 4, the bump 22 is a cylinder, and the distance between the first slot wall 311 and the second slot wall 312 of the sliding slot 31 is the same as the diameter of the bump 22. The convex block 22 is prevented from moving in the opposite direction of the first slot wall 311 and the second slot wall 312 while the convex block 22 is ensured to slide along the sliding slot 31, and the stability of the movement is ensured. However, the present disclosure does not limit the specific structure of the protruding block 22, and may be set according to the requirement.

Referring to fig. 2, 4 and 6, the front end of the wire 40 is provided with an ear seat 41, and the ear seat 41, the first link 1, the second link 2 and the third link 3 are respectively formed with flat plate portions and rotatably connected by a cylindrical pin after being overlapped with each other.
