Description

Hand cart

Technical Field

The invention relates to a trolley, in particular to a trolley for conveying a portable oil tank.

Background

Bulk transport vehicles for oil such as crude oil, gasoline or diesel are typically tanks that can be loaded onto trucks or train cars. Such transportation means usually require the opening of roads or railways. However, in a remote mountain area or in the case of traffic jam due to natural disasters, the vehicle body for transporting the oil tank is difficult to pass through, and oil needs to be divided into smaller volumes to be delivered to a destination in a convenient transportation manner. In order to meet the requirement of oil quality in areas where roads are difficult to pass due to natural disasters, when no natural disasters occur, the oil needs to be filled and stored in advance by a portable oil tank so as to improve the response time when the natural disasters occur. It is therefore desirable to design a cart for transporting portable fuel tanks.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. The terms "front", "back", "left", "right", "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. The terms "first" and "second" are used merely to simplify the description of words for distinguishing between similar objects and are not to be construed as specifying a sequential relationship between sequences.

Referring to fig. 1 and 2, the cart of the present invention includes a supporting body 1, a pull rod 2 mounted on the supporting body 1, and wheels 3. The bearing body 1 is provided with a rod holding groove 11 which is through from front to back and positioning bulges 12 which are positioned at two sides of the rod holding groove 11 and used for positioning the portable oil tank. The pull rod 2 is arranged at the front end of the rod containing groove 11 and can rotate relative to the bearing body 1. It should be noted that the front-back direction refers to a direction in which the cart travels, in which the front direction refers to a direction in which the cart is pulled to advance, and with respect to the supporting body, the front end refers to an end where the wheels are located as the front end, that is, an end where the pull rod is installed as the front end, and the opposite end is the rear end. The positioning of the positioning protrusion 12 on the portable oil tank means that a groove corresponding to the positioning protrusion 12 is formed in the bottom of the portable oil tank, and when the portable oil tank is placed on the supporting body, the positioning protrusion 12 correspondingly enters the corresponding groove, so that the portable oil tank is positioned relative to the supporting body.

And two sides of the bearing body 1 are respectively provided with a supporting component 4 which can rotate relative to the bearing body 1. The rotation of the supporting member 4 relative to the supporting body 1 allows the supporting member 4 to assume a folded state and an unfolded state. The unfolded state can be seen in fig. 1, two groups of supporting components 4 respectively rotate to two sides of the bearing body 1, the wheels 3 are in contact with the ground, and the portable oil tank can be transported at any time. The folded position can be seen in figure 3, in which the support member 4 is pivoted to the bottom of the carrier 1, reducing the space occupied by the trolley for easy storage.

Referring to fig. 2, each supporting assembly 4 includes a first supporting body 41 rotatably mounted on the front end of the supporting body 1, a second supporting body 42 rotatably mounted on the rear end of the supporting body 1, and a connecting body 43 connecting the first supporting body 41 and the second supporting body 42. The wheel 3 is mounted on the first support 41 and is rotatable with the first support 41. The carrier 1 is provided with a wheel accommodating groove 13 for accommodating the wheel 3 and a body accommodating groove 14 for accommodating the second support 42. When the support assembly 4 shown in fig. 3 is rotated and folded, the wheel 3 protrudes into the wheel-receiving groove 13, and the second support 42 protrudes into the body-receiving groove 14.

In this embodiment, the carrier 1 is mounted with a positioning pull pin 44 for fixing the support component 4. When the support member 4 is in the unfolded state, the positioning pull pin 44 abuts against the first support body 41, so that the support member 4 is positioned in the unfolded state. When it is desired to fold the support assembly 4, the pull tab of the positioning pull pin 44 is pulled outwardly, and the positioning pull pin 44 is released from contact with the first support body 41, at which time the support assembly 4 can be rotated to the folded position. Of course, in other embodiments, the positioning pull pin may not be provided.

Referring to fig. 1 and 4, as a further improvement of the present embodiment, a first hooking component 5 for hooking the top of the fuel tank can be installed on the pull rod 2. The first hooking component 5 comprises a first sleeving part 51 sleeved on the pull rod 2 and first hooking parts 52 respectively rotatably connected to two ends of the first sleeving part 51. The two first hooks 52 are respectively hooked with a cylinder disposed on the top of the portable fuel tank to increase the stability of the portable fuel tank. When not in use, the two first hooks 52 can be folded with respect to the first sleeve 51 for easy storage.

As a further improvement of this embodiment, a second hooking component 6 for hooking the bottom of the fuel tank can be installed on the pull rod 2. The second hooking component 6 comprises a second sleeve member 61 sleeved on the pull rod 2 and second hooking members 62 rotatably connected to two ends of the second sleeve member 61. The two second hooks 62 are respectively hooked with a cylinder disposed on the bottom of the portable fuel tank to increase the stability of the portable fuel tank. When not in use, the two second holding members 62 can be folded in a rotating manner relative to the second nesting member 61, so as to be convenient for storage.

Referring to fig. 5, the pull rod 2 can rotate relative to the carrier 1, and the pull rod 2 can rotate into the rod-containing groove 11 to reduce the occupied space and facilitate storage. As a further improvement of this embodiment, the pull rod 2 may be a telescopic pull rod, which further facilitates storage.

Finally, it should be noted that: the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Thus, although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted; all such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention and protected by the following claims.
