[0002] As a fitness equipment, the safety design of treadmill is very important. Among them, the design of treadmill handrails should not only consider the comfort and convenience of users, but also ensure the safety of users during use.

[0003] Traditional treadmill armrest locking mechanisms usually adopt a single locking mechanism, such as spring clamping or mechanical snapping, etc., such as a treadmill armrest frame proposed in publication number CN217548903U, in which a lock column is slidably arranged on one side of the insertion point at the end of the column on the dial frame or the armrest, and an elastic member is arranged between the lock column and the dial frame or the armrest. The elastic member applies force to the lock column so that the end of the lock column extends horizontally into the hole set on the column to lock it. However, this type of locking method has a certain stability, but it is not high. Therefore, how to improve the stability of the locking mechanism of the treadmill armrest is the purpose of this application.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0026] In the embodiments of this application, please refer to Figure 1-7As shown, the present application provides a treadmill armrest locking mechanism and a treadmill, which mainly include: an armrest shell 1; a column 2; an armrest frame 3, which is arranged inside the armrest shell 1, and a first fixing member 31 and a fixing seat 32 are installed at the bottom of the armrest frame 3, and a button groove 33 is opened, and a first limiting column 34 is installed on one side; a locking seat 4, which is installed on the top of the column 2, a locking groove 41 is opened on one side, and a first locking portion 42 extends on the other side; a rotating frame 5, which is installed inside the armrest frame 3, a connecting shaft 51 is provided at one end, and the other end is rotatably connected to the locking seat 4, and a torsion spring frame 52 is provided on the connecting shaft 51; a spring 65 locking block 6, which is arranged on the armrest frame 3, and one end of the spring locking member 6 is provided with A locking column 641 that cooperates with the locking groove 41 has a first pull rope 62 at the other end, and one end of the first pull rope 62 is locked by the first fixing member 31; a locking frame is rotatably arranged on the connecting shaft 51 and abuts against the top of the torsion spring frame 52, and a second locking portion 71 that cooperates with the first locking portion 42 extends from one end close to the torsion spring frame 52, and a second fixing member 72 is arranged at the other end, and the fixing seat 32 and the second fixing member 72 are connected by a second pull rope 74 and bypass the first limiting column 34; a button 8 is movably arranged in the button groove 33, and an abutting portion 81 is arranged on it, and the abutting portion 81 abuts against the bottom of the first pull rope 62 and the second pull rope 74.

[0027] Specifically, in the locked state, the first locking portion 42 and the second locking portion 71 are engaged with each other, and at the same time, the locking column 641 enters the locking groove 41, and both ends of the locking seat 4 are locked at the same time. At this time, the armrest has good stability; when the button 8 applies force inward, the first pull rope 62 and the second pull rope 74 are subjected to the pressure change of the abutment portion 81, and the first pull rope 62 pulls the locking column 641 out of the locking groove 41, and the second pull rope 74 drives the locking frame to rotate, so that the first locking portion 42 and the second locking portion 71 are no longer in contact, and the locking seat 4 is unlocked.

[0028] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0029] Reference Figure 6 As shown, the spring 65 locking block 6 includes a lock shell 63, a connecting column 64, and a spring 65. The lock shell 63 is arranged in the connecting groove 35, and the spring 65 is sleeved on the connecting column 64. The connecting column 64 passes through the locking shell and forms the locking column 641. In this way, when the button 8 presses the first pull rope 62, the connecting column 64 can synchronously drive the locking column 641 to be pulled out of the locking groove 41, and the spring 65 makes the locking column 641 automatically return to its position and enter the inside of the locking groove 41 when the button 8 is released.

[0030] Preferably, in order to facilitate the maintenance and installation of the spring locking member 6, a connecting portion 631 is provided at the bottom of the lock shell 63, and a connecting groove 35 is opened at the bottom of the handrail frame 3, and the lock shell 63 is inserted into the connecting groove 35 through the connecting portion 631.

[0031] Reference Figure 3 As shown, the connecting column 64 is screwed with the first connecting block 61 at the other end of the locking column 641, and one end of the first pull rope 62 is arranged on the first connecting block 61. The locking member is screwed with the second connecting block 73, and one end of the second pull rope 74 is arranged on the second connecting block 73. This arrangement allows the user to adjust the tightness of the first pull rope 62 and the second pull rope 74 by adjusting the screw connection depth of the first connecting block 61 and the second connecting block 73, and also facilitates the maintenance and installation of the first pull rope 62 and the second pull rope 74.

[0032] Reference Figure 4 As shown, a limiting ball 9 is fixedly provided at one end of the first pull rope 62 and the second pull rope 74, and the limiting ball 9 is clamped on the first fixing member 31 and the second fixing member 72. Through simple clamping, the installation between the first fixing member 31 and the second fixing member 72 and the first pull rope 62 and the second pull rope 74 is simpler.

[0033] Specifically, a second limiting column 36 is also provided on the armrest frame 3, and an arc is formed on the locking frame to cooperate with the second limiting column 36 and abut against the second limiting column 36. This arrangement allows the second limiting column 36 to be used as a fulcrum to facilitate the rotation of the locking frame.

[0034] Preferably, abutment plates 75 are installed on both sides of the locking frame, and the abutment plates 75 abut against the top of the torsion spring frame 52. This arrangement allows the locking frame to be driven to reset after unlocking the locking seat 4 and provide a fulcrum for the torsion spring frame 52 to support.

[0035] A treadmill comprises at least two groups of symmetrically arranged treadmill handrail locking mechanisms.
