Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a door panel handling rack. Background Technology

[0002] In furniture manufacturing, building decoration and other fields, door panels (such as solid wood door panels, composite door panels, etc.) need to be transferred between multiple workstations. Their sizes vary greatly, their surfaces are easily damaged, and multiple panels need to be transferred at the same time to improve efficiency. Therefore, the handling device must have the core capabilities of "adjustable size and lockable door panel stability". These two points directly determine the stability of the door panel and the versatility of the device during the handling process.

[0003] However, existing door panel handling devices have significant limitations in terms of "adjustable + lockable" functionality. Patent CN209321019U discloses a door panel turnover cart that uses multiple first conveyor belts and a liftable second conveyor belt for loading and unloading. However, the conveyor belt spacing is fixed, making it unsuitable for door panels of different heights. Furthermore, it relies solely on surface friction of the conveyor belts for support, lacking a lateral clamping and locking structure. Door panels are prone to lateral sliding due to bumps, compromising transport stability. Patent CN220535683U discloses a moving device with a motor-driven trailer. The front baffle of the trailer has a fixed height, making it impossible to adjust the protection range according to the door panel height, resulting in poor anti-fall performance for extra-tall door panels. Moreover, it relies solely on the bottom of the trailer for support, lacking a clamping and locking structure. When multiple door panels are stacked, they easily squeeze and slide against each other, failing to solve the problems of size adaptation and secure locking.

[0004] In addition, traditional door panel handling devices generally lack an integrated "adjustable + lockable" design, which either cannot be adapted to different sizes of door panels or is difficult to lock securely, resulting in low device versatility, high door panel damage rate during transportation, and inability to meet the needs of diverse handling scenarios. Utility Model Content

[0005] The present invention aims to provide a door panel transport rack to address the problem that existing traditional door panel transport devices lack an integrated "adjustable + lockable" design and cannot adapt to door panels of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a door panel transport rack, comprising a left side panel and a right side panel symmetrically arranged, a base connecting the bottom of the left side panel and the right side panel, a plurality of rollers connecting the bottom of the base, and the middle of the left side panel and the right side panel being fixedly connected by at least two parallel connecting rods, wherein the connecting rods are provided with a plurality of rectangular hollow clamping blocks along the length direction, and the clamping blocks are connected to the plurality of connecting rods by a sliding locking structure.

[0007] The principle of this solution is as follows: Place the door panel to be transported on the base. At this time, slide the clamping block horizontally close to the door panel along the connecting rod. When the clamping block is close to the door panel, rotate the clamping block to coincide with the door panel. At this time, the door panel is perpendicular to the connecting rod, and the clamping plate is limited and close to the door panel without moving. After placing the door panels in the limited position, push the left or right side panel for transport.

[0008] The advantages of this solution are: 1. A stable frame is formed by the symmetrically arranged left and right side plates and the base, coupled with bottom rollers, which can flexibly push the device to realize the transfer of door panels in multiple scenarios, reducing the intensity of manual handling; 2. The rectangular hollow clamping blocks on the connecting rod, combined with the sliding locking structure, can adjust the clamping position according to the thickness and width of the door panel, adapting to different sizes of door panels and solving the problem of poor adaptability of traditional devices; 3. Multiple clamping blocks can simultaneously clamp multiple door panels independently, avoiding the stacking and squeezing of door panels and reducing shaking during transfer; 4. The rectangular hollow design reduces the weight of the clamping blocks while ensuring clamping strength, reducing the overall load of the device and improving the flexibility of use.

[0009] Preferably, as an improvement, the sliding locking structure includes a channel within the top connecting rod and multiple limiting holes on the bottom connecting rod. The bottom of the top connecting rod has a groove communicating with the channel. A sliding block is connected to the top of the clamping block, passing through the groove and located within the channel. A limiting post matching the limiting holes is connected to the bottom of the clamping block. Through the cooperation of the channel and groove of the top connecting rod with the limiting holes of the bottom connecting rod, the "U"-shaped sliding block stably guides the clamping block to slide. The limiting post inserted into the limiting hole quickly locks the clamping position, preventing the clamping block from loosening and causing the door panel to shift during transport.

[0010] Preferably, as an improvement, the sliding block is shaped like an "𠃍". The "𠃍" shaped sliding block can be locked in the channel of the top connecting rod, which not only prevents the sliding block from falling out of the channel and affecting its use, but also ensures that the clamping block slides smoothly along the connecting rod, thereby improving the stability of the sliding locking structure.

[0011] Preferably, as an improvement, the sidewalls of the clamping block are adhered with an elastic buffer layer. The elastic buffer layer can form a buffer when the clamping block contacts the door panel, reducing the scratching and squeezing damage to the paint, wood grain or coating of the door panel surface caused by the clamping pressure, and protecting the appearance integrity of the door panel.

[0012] Preferably, as an improvement, the outer sides of the left and right side plates are provided with foldable handles, which are connected to the side plates via damping hinges. The foldable handles can be unfolded for easy application of force when the pushing device is needed, and folded when not in use to save storage space. The damping hinges can fix the unfolded angle of the handles, preventing them from rotating freely during pushing and improving operational convenience.

[0013] Preferably, as an improvement, the width of the base is greater than the length of the door panel. A wider base allows the door panel to be completely contained within the base, preventing the edges of the door panel from extending beyond the base and bumping into the ground or other objects during transport, thus further improving the stability of the door panel.

[0014] Figure 1 This is a structural schematic diagram of a door panel handling rack according to the present invention; Figure 2 for Figure 1 A schematic diagram of the sliding locking structure; Figure 3 for Figure 1 A schematic diagram of the structure of the clamping block.

[0015] The reference numerals in the accompanying drawings include: left side plate 1, sliding locking structure 2, upper connecting rod 201, channel 2011, clamping block 202, sliding block 2021, limiting post 2022, lower connecting rod 203, limiting hole 2031, right side plate 3, roller 4, and base 5. Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figure 1 As shown: A door panel transport rack includes a left side panel 1 and a right side panel 3 symmetrically arranged. A base 5 is fixedly connected between the bottom of the left side panel 1 and the right side panel 3. Four rollers 4 are rotatably connected to the bottom of the base 5. The width of the base 5 is greater than the length of the door panel. Foldable handles are provided on the outer sides of the left side panel 1 and the right side panel 3. The handles are connected to the side panels via damping hinges. Two parallel connecting rods are fixedly connected between the middle of the left side panel 1 and the right side panel 3. The connecting rods are divided into an upper connecting rod 201 and a lower connecting rod 203. Eleven rectangular hollow clamping blocks 202 are provided along the length direction between the upper connecting rod 201 and the lower connecting rod 203. The sidewall of 202 is attached with an elastic buffer layer by Velcro, and the clamping block 202 is connected to the two connecting rods by a sliding locking structure 2. The sliding locking structure 2 includes a channel 2011 in the upper connecting rod 201 and eleven limiting holes 2031 on the lower connecting rod 203. The bottom of the upper connecting rod 201 is provided with a sliding groove that communicates with the channel 2011. The top of the clamping block 202 is connected to a sliding block 2021 shaped like a "𠃍". The top of the sliding block 2021 passes through the sliding groove and is located in the channel 2011. The bottom of the clamping block 202 is fixedly connected to a limiting post 2022 that matches the limiting hole 2031.

[0017] The specific implementation process is as follows: Before use, the device is initially in the foldable handles on the outer sides of the left side panel 1 and the right side panel 3 are folded. The clamping block 202 is placed in the initial position of the slide groove of the upper connecting rod 201 through the sliding block 2021. The limiting post 2022 at the bottom of the clamping block 202 is not inserted into the limiting hole 2031 of the lower connecting rod 203. The elastic buffer layer is attached to the side wall of the clamping block 202. First, manually unfold the foldable handles on the outer sides of the left side panel 1 and the right side panel 3. Fix the handles at an angle that is easy to apply force through the damping hinge. Push the handles to move the device to the door panel storage position using the rollers 4 at the bottom of the base 5.

[0018] Next, according to the dimensions (thickness, length) of the door panels to be transported, one or more door panels are placed stably on the base 5 in sequence. Since the width of the base 5 is greater than the length of the door panel, the door panel can be completely placed within the range of the base 5, preventing the edges from exceeding the base 5. Then, adjust the corresponding rectangular hollow clamping block 202 for each door panel: first push the clamping block 202 along the slide groove of the upper connecting rod 201, and the "𠃍" at the top of the clamping block 202... The sliding block 2021 slides synchronously within the channel 2011 of the upper connecting rod 201, ensuring that the clamping block 202 moves smoothly along the length of the connecting rod until the elastic buffer layer on the side wall of the clamping block 202 is close to the surface of the door panel. Press the clamping block 202 downward, align the limiting post 2022 with the corresponding limiting hole 2031 on the lower connecting rod 203 and insert it. Then rotate the clamping block 202 to make it coincide with the plane of the door panel. At this time, the clamping block 202 is perpendicular to the connecting rod, and the top of the clamping block 202 is in contact with the inner wall of the channel 2011 of the top connecting rod. At this time, the locking of a single clamping block 202 is completed, realizing the lateral stable clamping of the door panel. If multiple door panels are transported, repeat the above sliding, rotating and locking steps, and fix each door panel separately with the independent clamping block 202 to avoid the door panels squeezing each other. After confirming that all door panels are clamped and locked, the pushing device moves to the target station through the roller 4.
