[0020] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, and the diagrams only show the components related to the present application, not the components number, shape and size when actually implemented. The actual implementation of each component type, number and proportion can be arbitrarily changed, and the component layout type can be more complex.

[0021] Embodiment:

[0022] A gas cylinder trolley, referring to the drawings, Figure 1 As shown, it comprises two mutually parallel arranged sleeve rods 1, the end of one end of the sleeve rod 1 is fixed with a supporting plate 2 perpendicular to the two sleeve rods 1; the other end of the two sleeve rods 1 is respectively sleeved with a handrail rod 3; the handrail rod 3 and the sleeve rod 1 together constitute the frame of the trolley, and the handrail rod 3 is fixed with a vertical downward supporting rod 12. The two sleeve rods 1 and the two handrail rods 3 are respectively connected with a hoop 7 for fixing the gas cylinder. Specifically, please continue to combine with the drawings, Figure 4 and Figure 5 As shown, the hoop 7 comprises an upper hoop body 7.1 and a lower hoop body 7.2, one end of the upper hoop body 7.1 is provided with an upper hinge lug 7.3, one end of the lower hoop body 7.2 is provided with a lower hinge lug 7.4, the upper hinge lug 7.3 and the lower hinge lug 7.4 are sleeved with a rotating shaft 7.5, the rotating shaft 7.5 is fixed on the sleeve rod 1 and the handrail rod 3, the upper hoop body 7.1 is hinged on the lower hoop body 7.2 through the rotating shaft 7.5; the other end of the upper hoop body 7.1 and the lower hoop body 7.2 is provided with a pin lug 7.6, the pin lug 7.6 is provided with a pin hole 7.7, a locking pin 7.8 passes through the pin hole 7.7 to lock the upper hoop body 7.1 and the lower hoop body 7.2. When transporting the gas cylinder, the two hoops can fix the gas cylinder to prevent the gas cylinder from falling off during transportation. The two sleeve rods 1 are also respectively fixed with a mounting rack 8, the mounting rack 8 is installed with a self-locking roller 9, after the gas cylinder is transported to the destination, the self-locking roller 9 can be locked to prevent the trailer from moving.

[0023] Specifically, in the actual gas cylinder transportation process, considering the difference in the length of the gas cylinder, therefore, the present application can adjust the distance between the two hoops 7 according to the length of the gas cylinder, so as to better fix the gas cylinder. Specifically, refer to the drawings, Figure 2 and Figure 3As shown, the inner wall of the handrail rod 3 is fixedly provided with a V-shaped elastic sheet 4, the V-shaped elastic sheet 4 is provided with a cylindrical protrusion 5, the cylindrical protrusion 5 passes through the handrail rod 3 under the action of the V-shaped elastic sheet 4 and forms a convex part on the outer wall of the handrail rod 3 which can be pressed inward, and the outer wall of the sleeve rod 1 is provided with a plurality of positioning holes 6 with the same center and matched with the cylindrical protrusion 5. The cylindrical protrusion 5 is matched in a certain positioning hole 6, thereby positioning the handrail rod 3. When the distance between the two hoops 7 needs to be increased, the cylindrical protrusion 5 is pressed inward by hand and the handrail rod is pulled outward, when the cylindrical protrusion 5 moves to the position of the lower positioning hole 6, the cylindrical protrusion 5 moves outward under the action of the V-shaped elastic sheet 4 and is matched in the positioning hole, thereby locking the handrail rod 3. Most preferably, in the embodiment, the outer wall of the sleeve rod 1 is provided with three positioning holes, and the distance between the positioning holes 6 is 10 cm. In actual application, other numbers and other distances of positioning holes can be set according to the length of the gas cylinder.

[0024] In the above embodiment, considering that the handrail rod 3 can rotate in the sleeve rod during pulling, thereby causing the cylindrical protrusion 5 to be unable to accurately move to the position of the lower positioning hole. Therefore, in the utility model, the Figure 6 As shown, the outer wall of the handrail rod 3 is inwardly recessed and forms a groove 10 on the surface of the outer wall of the handrail rod 3, the outer wall of the sleeve rod 1 is inwardly recessed and forms a protrusion 11 in the inner cavity of the sleeve rod 1, and the protrusion 11 is slidingly matched in the groove 10. During the sliding of the handrail rod 3 in the sleeve rod 1, the groove 10 and the protrusion 11 can guide the handrail rod 3, thereby ensuring that the cylindrical protrusion 5 can accurately move to the position of the lower positioning hole during pulling.

[0025] In the use process of the utility model, the distance between the two hoops 7 is adjusted according to the length of the gas cylinder, then the gas cylinder is placed on the lower hoop body 7.2 of the cart and the bottom is abutted on the supporting plate 2, then the upper hoop body 7.1 is rotated to fold the entire hoop 7, finally the locking pin 7.8 is inserted into the pin hole 7.7 to lock the hoop 7 and complete the fixation of the gas cylinder. When the gas cylinder is transported to the destination, the handrail rod 3 is lowered, the cart is supported on the ground through the supporting rod 12, and then the self-locking roller 9 is locked. At this time, the gas cylinder does not need to be removed from the cart, and the gas pipe can be directly connected to the gas cylinder for use. When the gas in the gas cylinder is almost used up, the empty gas cylinder can be removed from the cart.

[0026] The above-described embodiments only express the specific implementation of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection range of the utility model.
