Example two

Referring to fig. 2, on the basis of the first embodiment, the present embodiment specifically discloses a structure of a brake mechanism 600. The brake mechanism 600 includes a driving assembly 110 and a telescopic rod 100, and the driving assembly 110 drives the telescopic rod 100 to extend and retract to touch or not touch the ground, so that the friction force generated when the telescopic rod 100 touches the ground is utilized to brake.

As an alternative to this embodiment, the driving assembly 110 may be an electric push rod, and the electric push rod drives the telescopic rod 100 to implement braking.

Referring to fig. 3, as another alternative of the present embodiment, the driving assembly 110 includes a sleeve 113, the sleeve 113 is hollow, an elastic element 112 is disposed in the sleeve 113, and an inner wall of the sleeve 113 is further slidably connected to the telescopic rod 100.

Optionally, the resilient element 112 is a spring.

Therefore, the motor or the brake handle 140 can drive the direct traction unit 111 to stretch the telescopic rod 100, so that the telescopic rod 100 slides in the sleeve 113 and the elastic element 112 is compressed in the sleeve 113, and at the moment, the telescopic rod 100 gradually leaves the ground, thereby realizing the purpose of no braking. When the brake handle 140 is released, the telescopic rod 100 is extended outward of the sleeve 113 by the elastic member 112 until it touches the ground and generates a frictional force for braking. It can be seen that the elastic element 112 always processes the compression state to generate the thrust force to the telescopic rod 100.

In order to improve the braking effect, a foot pad 101 for increasing friction is provided at the bottom of the telescopic rod 100.

In order to prevent the telescopic rod 100 from slipping out of the sleeve 113, a stepped boss 102 is provided on the outer wall of the telescopic rod 100, and a stopper 114 for stopping the boss 102 is mounted on the sleeve 113. Optionally, the limiting member 114 is a screw, and the extension length of the telescopic rod 100 can be further limited by blocking the boss 102 with the screw.

The moving table provided by the embodiment drives the telescopic rod 100 to touch the ground through the driving component 110 to generate friction force, the brake is realized by utilizing the friction force, the problem that the brake cannot be realized in the prior art is solved, and the brake mechanism 600 is simple in structure and convenient to realize.

Further, in order to protect the components inside the brake mechanism 600 and to beautify the appearance, a cover 201 is provided outside the brake mechanism 600.

EXAMPLE III

Referring to fig. 2 and 4, based on the second embodiment, the brake mechanism 600 further includes a fixing plate 120, a plurality of sleeves 113 are disposed on the fixing plate 120, and each sleeve 113 corresponds to one telescopic rod 100, so that a plurality of direct traction members 111 are provided.

In order to synchronously control the plurality of direct traction members 111, a guide seat 151 is disposed in the middle of the fixing plate 120, a plurality of guide holes 152 for penetrating the direct traction members 111 are disposed on the guide seat 151, and all the direct traction members 111 are connected to a lifting block 153 after penetrating through the guide holes 152.

Therefore, the brake handle 140 controls the lifting of the lifting block 153 to synchronously control all the direct traction members 111, thereby controlling the telescopic rod 100 to synchronously brake or not brake.

Example four

Referring to fig. 2 and 4, based on the third embodiment, the brake mechanism 600 further includes an integrated pulley assembly 150, the integrated pulley assembly 150 includes a first pulley 154 and a second pulley 155 which are coaxial, a radius of the first pulley 154 is not equal to a radius of the second pulley 155, the first pulley 154 is connected to the brake handle 140 by a first indirect traction member 161, and the second pulley 155 is connected to the lifting block 153 by a second indirect traction member 162. Specifically, the first indirect drawing member 161 passes through the inside of the fixing tube 170 and is coupled to the brake handle 140.

When the radius of the first pulley 154 is larger than the radius of the second pulley 155, and the brake handle 140 is operated, since the input drive is the first pulley 154, the first indirect traction member 161 can be driven with a small force, and the direct traction member 111 obtains a large force, thereby improving the braking and non-braking effects, which is a labor-saving and non-distance-saving mode.

When the radius of the first pulley 154 is smaller than the radius of the second pulley 155, when the brake handle 140 is operated, since the input drive is the first pulley 154, the first indirect traction member 161 moves a smaller distance, and the direct traction member 111 can move a larger distance, thereby also improving the braking and non-braking effects, which is a distance-saving and non-labor-saving mode.

The mobile workbench provided by the embodiment can obtain the advantage of labor saving or distance saving by transmitting the power of the brake handle 140 through the integrated pulley assembly 150, and the braking and non-braking effects are improved.
