AI Technical Summary
Some side-opening containers on the market cause semi-trailers to become unstable during unloading, posing a risk of tipping over.
By using cylinders installed in rectangular slots on both sides of the semi-trailer container to move counterweights, the center of gravity is changed to enhance balance and prevent tipping.
It effectively prevents semi-trailers from tipping over due to an unstable center of gravity, improves safety, and enhances the stability of the counterweight by using a sliding rod and a fixing sleeve.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of anti -toppling safety device, especially relates to a semi -trailer anti -toppling safety device. BACKGROUND
[0002] The semi -trailer is a kind of axle is placed in the center of gravity when the vehicle is evenly loaded, and the trailer is equipped with the coupling device of the horizontal and vertical force transmission to tractor.The semi -trailer is mainly composed of frame, axle, wheel, suspension system, brake system, electrical system etc., and needs to use container for cargo transportation.
[0003] But some side opening door containers on the market when using, usually unload in one side, when a batch of goods is unloaded, the center of gravity of container is unstable, so as to cause the semi -trailer to incline, and there is certain security risk. UTILITY MODEL CONTENTS
[0004] To solve the problems in the prior art, the utility model provides a semi -trailer anti -toppling safety device, moves the counterweight by the cylinder, moves out the inside of rectangular groove, changes the center of gravity of semi -trailer, and then strengthens the balance of semi -trailer container body, prevents the semi -trailer container body from toppling due to unstable center of gravity, and strengthens the safety during use.
[0005] To achieve the above object, the utility model provides the following technical scheme: a semi -trailer anti -toppling safety device, including semi -trailer container body, the left and right sides of semi -trailer container body are each provided with two rectangular grooves, the inside of rectangular groove is fixedly connected with fixed block, the top of fixed block is fixedly connected with cylinder, one end of cylinder is fixedly connected with counterweight, the inside of rectangular groove is fixedly connected with two sliding rods, sliding rod is movably penetrated through counterweight, the surface of sliding rod is movably sleeved with fixed sleeve.
[0006] Further, two sliding rods are located at the two sides of cylinder.
[0007] Further, one end of fixed sleeve is fixedly connected with the surface of counterweight.
[0008] Compared with the prior art, the utility model has the advantages of:
[0009] 1. the cylinder moves the counterweight, moves out the inside of rectangular groove, changes the center of gravity of semi -trailer, and then strengthens the balance of semi -trailer container body, prevents the semi -trailer container body from toppling due to unstable center of gravity, and strengthens the safety during use.
[0010] 2. the stability of counterweight can be enhanced when moving by the setting of sliding rod and fixed sleeve.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS

[0014] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0015] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. EMBODIMENT
[0016] Referring to the drawings Figs. 1-2 As shown in the figure, a semi-trailer anti-toppling safety protection device includes a semi-trailer container body 1, two rectangular grooves 2 are formed on the left and right sides of the semi-trailer container body 1 respectively, a fixed block 3 is fixedly connected inside the rectangular groove 2, an air cylinder 4 is fixedly connected to the top end of the fixed block 3, a counterweight 5 is fixedly connected to one end of the air cylinder 4, two slide bars 7 are fixedly connected inside the rectangular groove 2, the slide bars 7 are movably penetrated through the counterweight 5, and a fixed sleeve 6 is movably sleeved on the surface of the slide bar 7.
[0017] The two slide bars 7 are located on the two sides of the air cylinder 4 respectively.
[0018] One end of the fixed sleeve 6 is fixedly connected to the surface of the counterweight 5.
[0019] Working principle: when using, the semitrailer container body 1 is installed on the semitrailer, when it is needed to unload from the side of the semitrailer container body 1, the goods inside the semitrailer container body 1 are unloaded from one side, which will cause more goods to remain on the side far from the unloading direction, resulting in unstable center of gravity, at this time, the two air cylinders 4 on the unloading direction side can be started, the counterweight 5 is driven to move by the air cylinder 4, so that it moves out of the inside of the rectangular groove 2, so as to change the center of gravity of the semitrailer, and then strengthen the balance of the semitrailer container body 1, prevent the semitrailer container body 1 from falling due to unstable center of gravity, and strengthen the safety during use, through the setting of the slide rod 7 and the fixed sleeve 6, the stability of the counterweight 5 during movement can be enhanced.
[0020] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, for those skilled in the art, obviously, the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model, therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, the scope of the utility model is defined by the appended claims instead of the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model, any figure reference in the claims should not be regarded as limiting the involved claims.
