Description

Technical Field

[0001] This utility model relates to the technical field of detachable fixing brackets for trailer interiors, specifically to a detachable fixing bracket for trailer interiors. Background Technology

[0002] As a crucial carrier for freight transport, the stability of the cargo inside a trailer directly impacts transportation safety and loading / unloading efficiency. Currently, most trailer internal securing devices on the market employ fixed railings, straps, or simple baffle structures, which have numerous limitations in practical applications. Traditional securing structures are typically welded frames, unable to be flexibly adjusted according to cargo dimensions, resulting in low space utilization. While some adjustable brackets using bolt connections offer some adjustment capabilities, the assembly and disassembly process is cumbersome, and they lack multi-dimensional positioning capabilities, making it difficult to adapt to the transportation needs of cargo at different heights.

[0003] In recent years, although some fixed frame designs with lifting functions have emerged, such as those using hydraulic lifting or manual gear adjustment devices, these solutions still have obvious drawbacks: hydraulic systems have complex structures, high maintenance costs, and are difficult to achieve precise positioning; manual adjustment methods are inefficient and cannot meet the needs of rapid loading and unloading operations.

[0004] To address the aforementioned technical issues, a trailer internal securing device with multi-directional adjustment, quick disassembly and assembly, and high adaptability is designed to improve cargo securing efficiency, enhance transportation safety, and reduce equipment maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable fixing bracket for the interior of a trailer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable fixing frame for the interior of a trailer, comprising a frame, a base, columns, a lifting seat, and a fixing mechanism, characterized in that: a base is provided below the bottom of the frame, the base is connected to the frame by four columns distributed and fixed around the base, each of the four columns has a lifting groove on its surface, each lifting groove has a vertically installed lifting screw, the end of the lifting screw is driven by four lifting motors fixed above the frame, the four lifting screws are symmetrically slidably connected to a lifting seat, and a fixing mechanism is provided inside the lifting seat, the fixing mechanism consisting of a longitudinal fixing component and a transverse fixing component.

[0007] Preferably, the interior of the lifting seat is hollowed out in the shape of a square, and its four ends are connected to the lifting screw for screw transmission.

[0008] Preferably, the longitudinal fixing assembly includes a longitudinal motor, a longitudinal double-threaded screw, a longitudinal groove, a longitudinal slider, and a longitudinal clamping plate. There are two longitudinal drive motors, which are respectively disposed at both ends of one side of the lifting seat. Two longitudinal grooves are parallel and symmetrically opened on both sides of the inner wall of the lifting seat. A longitudinal double-threaded screw is disposed in each of the two longitudinal grooves. The end of the longitudinal double-threaded screw is connected to the output end of the longitudinal motor. Two longitudinal sliders are slidably connected to the outside of the longitudinal double-threaded screw. The two longitudinal double-threaded screws form four longitudinal sliders that are fixedly connected to the two ends of the two longitudinal clamping plates.

[0009] Preferably, the lateral fixing assembly includes a lateral motor, a lateral double-threaded screw, a lateral groove, a lateral slider, and a lateral clamping plate. A lateral groove is provided in the center of the base, and a lateral double-threaded screw is provided in the lateral groove. The end point of the lateral double-threaded screw is driven and connected to a lateral motor provided on the outer side of the base. Two lateral sliders are slidably connected to the outside of the lateral double-threaded screw, and two lateral clamping plates are fixed on one side of the two lateral sliders.

[0010] Preferably, a limiting block is sleeved in the middle of the longitudinal double-threaded screw and the transverse double-threaded screw, and the screw threads on both sides of the limiting block are opposite threads.

[0011] Preferably, the longitudinal clamping plate and the transverse clamping plate are rectangular plates, and their clamping surfaces are coated with an anti-slip layer.

[0012] Preferably, the longitudinal clamping plate and the transverse clamping plate can be used to fix different materials in multiple dimensions by controlling the motor drive.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a lifting motor to drive the lifting screws in the four columns for synchronous transmission, which drives the lifting seat to adjust its height. This enables precise vertical positioning of the fixing mechanism and effectively adapts to the fixing needs of goods of different heights. At the same time, the longitudinal fixing component adopts a symmetrical longitudinal double-threaded screw structure driven by two motors, which allows the two sets of longitudinal clamping plates to move synchronously in both directions along the longitudinal groove. Combined with the transverse clamping plate driven by the transverse double-threaded screw, a three-dimensional clamping space is formed, breaking through the single-dimensional adjustment limitation of traditional fixing frames and accurately matching the shape characteristics of various irregular goods.

[0015] 2. The base and frame are connected by column bolts in a split design, which enables the overall frame to be quickly disassembled and reassembled; the lifting seat adopts a hollow U-shaped structure and has a built-in vertical drive module that can operate independently, which reduces maintenance complexity while ensuring structural strength. This design means that the equipment does not need to be replaced as a whole when partial damage occurs, which significantly reduces maintenance costs and downtime. Attached Figure Description

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims.

[0020] like Figures 1 to 2 As shown, this embodiment provides a detachable fixing frame for the interior of a trailer: including a frame 1, a base 2, columns 3, a lifting seat 7, and a fixing mechanism. The frame 1 is a rectangular frame structure, welded from high-strength aluminum alloy profiles. The bottom is connected to the base 2 through four columns 3. The base 2 has bolt holes at its four corners and is detachably connected to the trailer floor plate by bolts. The columns 3 are vertically fixed to the four corners of the base 2. Each column has a lifting groove 4 of the same height on its surface. A lifting screw 5 is installed in the lifting groove 4. The upper end of the lifting screw 5 is connected to the output shaft of the lifting motor 6 at the top of the frame 1 through a coupling. The four lifting motors 6 are driven at the same speed through a synchronous controller.

[0021] The lifting seat 7 is a hollow U-shaped frame with screw nuts at the four corners that match the lifting screw 5. It can move vertically along the column 3 by being driven by the lifting motor 6. The lifting seat 7 has longitudinal fixing components 8 symmetrically arranged on both sides inside, and a transverse fixing component 9 is embedded in the middle of the base 2.

[0022] The longitudinal fixing component 8 includes two sets of longitudinal motors 81, longitudinal double-threaded screws 82, longitudinal grooves 83, longitudinal sliders 84, and longitudinal clamping plates 85. The longitudinal motors 81 are installed at both ends on one side of the lifting seat 7, driving the two parallel longitudinal double-threaded screws 82 to rotate. A limit block 10 is provided in the middle of the screw, and the threads on both sides are opposite, driving the two pairs of longitudinal sliders 84 to slide in opposite directions in the longitudinal grooves 83, so that the two longitudinal clamping plates 85 move closer or further away at the same time.

[0023] The lateral fixing component 9 includes a lateral motor 91, a lateral double-threaded screw 92, a lateral groove 83, a lateral slider 84, and a lateral clamping plate 85. A lateral groove 93 is provided in the center of the base 2. A lateral double-threaded screw 92 is provided in the lateral groove 93. The end point of the lateral double-threaded screw 92 is connected to the lateral motor 91 located on the outside of the base 2. The lateral motor 91 drives the lateral double-threaded screw 92 to rotate, which drives the two lateral sliders 94 to move in opposite directions along the lateral groove 93, and pushes the two lateral clamping plates 95 to clamp the goods horizontally.

[0024] Working principle: Four lifting motors 6 receive the same command through a synchronous controller, driving four lifting screws 5 to rotate synchronously, which in turn drives the lifting seat 7 to move vertically along the column 3. Since the four lifting screws 5 use the same thread parameters and synchronous control, the lifting seat 7 always remains horizontal, avoiding jamming caused by tilting, and ensuring that the fixing mechanism is accurately positioned at the height of the goods. The longitudinal double-threaded screw 82 forms two reverse threads under the separation of the limit block 10. When the longitudinal motor 81 drives the screw to rotate, the two longitudinal sliders 84 drive the longitudinal clamping plates 85 to move in opposite directions, realizing symmetrical pressure on the goods and eliminating the goods deviation caused by unilateral force. The transverse double-threaded screw 92 also adopts a reverse thread design, driving the two transverse clamping plates 95 to clamp synchronously from both sides of the bottom of the goods. The base 2 is connected to the trailer floor plate by bolts. When disassembling, only the bolts need to be removed to remove the entire fixing frame, which can adapt to the reuse needs of different trailers.

[0025] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
