Referring to fig. 1, the present embodiment provides a mobile workbench, which includes a brake mechanism 600, wherein the brake mechanism 600 includes a fixed tube 170, the fixed tube 170 is connected to a first connecting tube 300, and the first connecting tube 300 is connected to a second connecting tube 400.

The fixing pipe 170 and the first connection pipe 300, and the first connection pipe 300 and the second connection pipe 400 are detachably connected through the quick release structure 500, so that the movable table can be quickly assembled and disassembled.

Specifically, the bottom of the brake mechanism 600 is provided with wheels 130, and the moving table moves by rolling the wheels 130.

Example two

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

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

Referring to fig. 3, as an alternative to this 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. A direct traction member 111 is provided through the top of the sleeve 113 and the elastic member 112, and one end of the direct traction member 111 is connected to the telescopic rod 100, and the other end is connected to the brake handle 140 or the motor. Alternatively, the elastic element 112 is a spring.

Therefore, the motor or the brake handle 140 can drive the direct traction piece 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 this time, the telescopic rod 100 gradually leaves the ground to realize no braking. When the brake handle 140 is released, the telescopic rod 100 extends outwardly from the sleeve 113 by the elastic member 112 until it touches the ground and generates friction for braking. It can be seen that the elastic element 112 always processes the compression state to generate the pushing force to the telescopic rod 100.

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 sliding 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 preventing 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 may be limited by blocking the boss 102 by the screw.

The movable workbench provided by the embodiment drives the telescopic rod 100 to touch the ground through the driving component 110 to generate friction, and realizes braking by utilizing the friction, so that the problem that the prior art cannot brake is solved, and the brake mechanism 600 is simple in structure and convenient to realize.

Further, the housing 201 is provided outside the brake mechanism 600 for protecting the components in the brake mechanism 600 and for beautifying the appearance.

Example III

Referring to fig. 2 and 4, in addition to the second embodiment, the brake mechanism 600 further includes a fixing plate 120, and a plurality of sleeves 113 are disposed on the fixing plate 120, where each sleeve 113 corresponds to a telescopic rod 100, and thus has a plurality of direct traction members 111.

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 with a lifting block 153 after penetrating the guide holes 152.

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

Example IV

Referring to fig. 2 and 4, based on the third embodiment, the brake mechanism 600 further includes an integral pulley assembly 150, the integral pulley assembly 150 includes a first pulley 154 and a second pulley 155 that are coaxial, the radius of the first pulley 154 is unequal to the radius of the second pulley 155, the first pulley 154 is connected to the brake handle 140 through a first indirect traction member 161, and the second pulley 155 is connected to the lifting block 153 through a second indirect traction member 162. Specifically, the first indirect traction member 161 passes through the inside of the stationary pipe 170 and is connected to the brake handle 140.

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

When the radius of the first pulley 154 is smaller than that of the second pulley 155, the first indirect traction member 161 can be moved a relatively small distance due to the input driving of the first pulley 154 when the brake handle 140 is operated, so that the direct traction member 111 can be moved a relatively large distance, thereby improving the braking and non-braking effects, which is a distance-saving and labor-saving mode.

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

For another example, when the control host 301 supplies power to the LED lamp 401 and the camera 402 on the second connection tube 400, the first electronic connector 50 and the second electronic connector 60 are a USB female port and a USB male port, respectively, as an alternative.
