Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The safe gas cylinder cart shown in the attached figures 1 to 6 comprises a cart frame 1, a plurality of travelling wheels 2 installed at the bottom of the cart frame, a handle 3 installed at the upper end of the cart frame, a supporting plate 4 used for supporting the bottom of a gas cylinder and a cart self-locking device. Wherein the bearing plate 4 is arranged at one end of the bottom of the frame. The frame 1 is integrally triangular and comprises a support frame 5 and a support bracket 6 for supporting the gas cylinder body. The support bracket 6 is obliquely arranged, the support bracket 6 is inwards concave in an arc shape, and the gas cylinder is placed in the concave part of the support bracket 6.

At least one of the travelling wheels 2 is a self-locking wheel 7, and the self-locking wheel 7 can be matched with a self-locking device of the trolley to generate a self-locking effect. The self-locking wheel 7 is provided with a plurality of self-locking holes 8. The cart self-locking device comprises a pull handle 9, a conducting wire and a bolt 11. The bolt 11 is arranged on one side of the self-locking wheel 7, and the bolt 11 is correspondingly inserted into the self-locking hole 8. The two ends of the conducting wire are respectively connected with the pull handle 9 and the bolt 11.

When the cart is in a standing state, the bolt 11 and the self-locking hole 8 are correspondingly inserted and combined, and wheels are locked to prevent the cart from sliding. When the cart needs to be moved, an operator pulls the pull handle 9, the pull handle 9 drives the plug pin 11 to retract through the conducting wire, the plug pin 11 is separated from the self-locking hole 8, and therefore the self-locking state of the cart is relieved, and the cart further moves normally.

A first connecting piece 12 is fixed on the handle 3, and a first connecting hole 13 is formed in the first connecting piece 12. One end of the conductive wire passes through a first connecting hole 13 on the first connecting piece 12 to be connected with the pull handle 9, the pull handle 9 slides along the first connecting hole 13, and the pull handle 9 abuts against one side hole opening of the first connecting hole 13. The position of the pull handle 9 is relatively fixed due to the abutting arrangement.

A second connecting piece 14 is fixed on one side of the self-locking wheel 7, a second connecting hole 15 is formed in the second connecting piece 14, the other end of the conducting wire penetrates through the second connecting hole 15 in the second connecting piece 14 to be connected with the bolt 11, the bolt 11 slides along the second connecting hole 15, and the bolt 11 is abutted to an orifice on one side of the second connecting hole 15 through an elastic piece 16. The abutting arrangement makes the position of the bolt 11 relatively fixed. The elastic piece 16 can press the bolt 11 and the self-locking hole 8 to be correspondingly inserted and combined, and plays a role in resetting the pull handle 9 and the bolt 11 after the pull handle 9 is loosened.

The self-locking holes 8 are cylindrical round holes, the self-locking holes 8 are arranged on the side planes of the self-locking wheels 7, and the self-locking holes 8 are circumferentially and uniformly distributed along the rotating shafts of the self-locking wheels 7. The orifice of the self-locking hole 8 is provided with a circle of shrink rings 20 inwards, and the radius of the orifice of the self-locking hole 8 is smaller than the inner radius of the self-locking hole 8 through the shrink rings 20.

The bolt 11 is bullet-shaped and hollow inside; a clamping groove 17 is formed in the side arc surface of the bolt 11, and the clamping groove 17 is communicated with the inner cavity of the bolt 11 through a clamping hole 30 in the bottom of the groove. A clamping block 18 is arranged in the clamping groove 17, and an elastic gasket 19 is arranged at the bottom of the clamping block 18; the end of the conducting wire sequentially passes through the second connecting hole 15, the inner cavity of the bolt 11, the clamping hole 18 and finally is connected with the clamping block 18.

When the bolt 11 is inserted into the self-locking hole 8, the fixture block 18 protrudes out of the side surface of the bolt 11 under the elastic force of the elastic gasket 19, the fixture block 18 abuts against the shrink ring 20 to prevent the bolt 11 from being separated from the self-locking hole 8, and the matching stability of the bolt 11 and the self-locking hole 8 is improved. When the handle 9 pulls the conductive wire, one end of the conductive wire close to the bolt 11 firstly pulls the fixture block 18, and the fixture block 18 compresses the elastic gasket 19 and then sinks into the clamping groove 17, so that the bolt 11 can be smoothly separated from the self-locking hole 8.

An arc-shaped transition surface is arranged on one side of the contraction ring 20, which is close to the outside of the self-locking hole 8, and an arc-shaped transition surface is also arranged on one side of the fixture block 18, which is close to the tail end of the bolt 11. So that when the pull handle 9 is released and the elastic piece 16 drives the bolt 11 to reset, the bolt 11 can enter the self-locking hole 8 more easily.

The handle 3 and the pull handle 9 are both of a U-shaped structure consisting of three sections of supporting rods, the pull handle 9 is arranged on the inner side of the handle 3, and each section of supporting rod of the pull handle 9 is correspondingly parallel to each section of supporting rod of the handle 3. As shown in the attached drawings, when an operator pulls the pull handle 9, the operator only needs to pull the pull handle 9 and the middle section of the U-shaped structure of the handle 3, and the machine can complete the operation. The action of pulling the pull handle 9 and the action of holding the handle 3 to push the cart are unified, and the integral structure is more reasonable.

The number of the travelling wheels 2 is four, and the travelling wheels comprise two front wheels 21 and two rear wheels 22; the two front wheels are self-locking wheels 7, the front wheels 21 are fixed to the bottom of the frame 1 through fixing frames 23, the moving direction of the front wheels 21 is fixed, and the stability of matching of the self-locking holes 8 and the bolts 11 is guaranteed. The two rear wheels 22 are fixed at the bottom of the frame 1 through the rotating frame 24, and the moving direction of the rear wheels 22 can be changed, so that the limitation of the moving direction of the cart is greatly reduced, and the cart is more convenient to use.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
