[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0017] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a strength enhancement structure of a lightweight chassis, comprising a plurality of clamping rods 2 and a plurality of positioning tubes 1, wherein the positioning tubes 1 are laterally arranged opposite to each other, one end of the clamping plates are inserted into the opposite openings of the positioning tubes 1, a driving mechanism is installed in the middle of the positioning tubes 1 for synchronously driving the clamping rods 2 to be clamped and fixed on the chassis, a connecting plate 3 is installed between the positioning tubes 1, a plurality of first fixing blocks 4 are installed on the opposite side of the clamping plate and on the side of the positioning tube 1 away from the connecting plate 3, a plurality of second fixing blocks 5 are installed on the side of one lateral end of the clamping plate, and a roller 8 is installed on both the first fixing block 4 and the second fixing block 5.

[0019] In this embodiment, the driving mechanism includes a rotating hand wheel 12 and a screw rod 11. The opposite end surfaces of the clamping rod 2 are provided with screw rod holes. Both ends of the screw rod 11 are threadedly connected to the screw rod holes. The rotating hand wheel 12 is installed in the middle of the screw rod and is exposed.

[0020] The screw rod can be driven to move the clamping rod inwardly to be clamped on the chassis, and after the screw rod is rotated in the reverse direction, the clamping rod can be opened outwardly, so that the device can be directly disassembled from the chassis, which increases convenience.

[0021] In this embodiment, the cross-section of the inner cavity of the positioning tube 1 and the cross-section of the clamping plate are both arranged in a rectangular structure, and the outer side surface of the clamping rod 2 is in contact with the inner wall surface of the positioning tube 1, so that the clamping rod can only move horizontally along the positioning tube, avoiding the rotation of the clamping rod.

[0022] In this embodiment, mounting holes are provided in the middle of the first fixed block 4 and the second fixed block 5, and sealed bearings 14 are installed in the mounting holes. A rotating shaft is installed on the top surface of the drum 8, and the upper end of the rotating shaft passes through the inner ring of the sealed bearing 14. A positioning ring 15 is installed on the rotating shaft, and the top surface of the positioning ring 15 contacts the bottom surface of the first fixed block 4 or the second fixed block 5. A nut 9 is threadedly connected to the upper end of the rotating shaft, and the bottom surface of the nut 9 contacts the top surface of the first fixed block 4 or the second fixed block 5.

[0023] Among them, after removing the nut, the shaft rod can be directly taken out from the sealed bearing, thereby facilitating the disassembly and replacement of the roller and avoiding the impact of the buffering effect due to damage to the roller.

[0024] In this embodiment, one side of the second fixing block 5 protrudes to form a fixing portion 6, and a fixing hole is provided on the fixing portion 6. A plurality of screw holes 13 are provided on the outer side surface of one lateral end of the clamping plate. Bolts are threadedly connected in the relative fixing holes and the screw holes 13. The bolt fixing method facilitates the subsequent disassembly of the second fixing block and avoids affecting the inward movement of the clamping rod.

[0025] During installation, since one side of the chassis is generally set against the wall, the device does not need to be protected on all four sides. The clamping rod can be sleeved on both sides of the chassis, and the connecting plate can be against the front of the chassis. After turning the rotating hand wheel, the rotating hand wheel can drive the screw rod, and the rotating screw rod can drive the clamping rod to move inward along the positioning tube until it is clamped and fixed on the outside of the chassis. The moved clamping rod can be locked and positioned by the screw rod to ensure the firmness of the clamping;

[0026] Among them, as the clamping rod extends out of the positioning tube or retracts into the positioning tube, the number of exposed screw holes will change, so that different numbers of second fixing blocks can be installed to ensure the protection effect of the lateral end of the clamping rod and avoid gaps that affect the protection of the front of the chassis.

[0027] When the chassis is impacted by the outside, it will first come into contact with the external roller. After contacting the roller, the roller can convert the impact force into rotational force, thereby effectively protecting the chassis and reducing the probability of chassis damage. The roller can also be quickly installed and disassembled, making replacement convenient.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
