Description

Technical Field

[0001] This utility model belongs to the technical field of cargo limiting devices, specifically relating to a hidden anti-deviation baffle device for heavy-duty logistics equipment, which is particularly suitable for cargo blocking scenarios on airport trailers or roller conveyors. Background Technology

[0002] In airport logistics and transportation, trailers or roller conveyors are core equipment for cargo transfer. To prevent cargo from slipping during transfer, baffles are usually installed on the equipment. In the existing technology, the hand-held baffles used on trailers or roller conveyors are generally equipped with operating holes or handles. When operating, force needs to be applied from the side to fasten the baffle to form a blocking structure. This requires that sufficient clearance be reserved on the side of the baffle to accommodate the handle or the operator's hand.

[0003] The above structure has two major drawbacks: first, it imposes significant limitations on equipment installation space, and the requirement for side clearance space makes it impossible for the baffle to fit the compact layout of trailers or roller conveyors; second, the baffle is not strong enough, and in order to install operating holes or handles, notches need to be made in the steel plates on both sides of the baffle, which will significantly weaken the overall structural strength of the baffle. When blocking heavy loads, the baffle is prone to deformation or breakage due to stress concentration, posing a safety risk of goods slipping. Therefore, in order to solve the above technical problems, the technical solution of this application is proposed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing handheld baffles, which require side clearance space and have insufficient strength, and to provide a hidden anti-deviation baffle device for heavy-duty logistics equipment. This device enables operation from above the baffle to eliminate side space restrictions, eliminates the notches on both sides of the baffle to enhance structural strength, and ensures operational reliability through a limiting structure.

[0005] The technical solution adopted in this utility model is as follows: A concealed anti-deviation baffle device for heavy-duty logistics equipment includes two parallel first mounting plates and two parallel second mounting plates. The first mounting plates are fixedly connected to the trailer or roller conveyor by bolts to ensure installation stability. A space is reserved between the two sides of the first mounting plates to accommodate the second mounting plates. The second mounting plates are perpendicular to the first mounting plates and are detachably connected by snap-fit ​​mechanisms for easy maintenance and replacement. The height of the first mounting plates is less than the height of the second mounting plates, and the height direction of the second mounting plates is parallel to the upper surface of the trailer or roller conveyor, providing sufficient space for the rotation of the baffle.

[0006] A rotatable baffle is provided between the two second mounting plates. The baffle can rotate up and down around the second mounting plates: when rotated upwards, the baffle stands upright to block the movement of goods (working state); when rotated downwards, the baffle is completely hidden under the trailer or roller conveyor (storage state), requiring no additional space. A first opening slot is provided at the top of one end of the baffle, allowing the operator to reach in from above and use a tool to grip the first opening slot, thus enabling the rotation of the baffle and completely eliminating the need for side clearance space.

[0007] The core working principle of this utility model is based on the synergistic effect of "rotation + limiting". Through structural design, the baffle is hidden and stably blocked, as follows: Rotation transmission principle: The baffle is connected to the rotation shaft of the second mounting plate through a rounded rectangular slot, forming a hinge structure that can rotate around the rotation shaft; the design of the length direction of the rounded rectangular slot allows the baffle to move up and down along the axis of rotation, providing travel space for the baffle to disengage from / engage with the limiting post.

[0008] Limit positioning principle: Two sets of limit matching structures are set: Storage limit: When the baffle rotates downward, the engagement of the second opening slot with the first limiting post and the third opening slot with the second limiting post limits the horizontal position of the baffle, preventing excessive rotation that would prevent subsequent upward operation; Working limit: When the baffle rotates upward, the engagement of the fourth opening slot with the first limit post limits the vertical position of the baffle, ensuring that the baffle does not shift under the impact of the goods and ensuring blocking stability.

[0009] Operating principle: By replacing the traditional side operation with "top operation", the operator applies an upward force through the first opening slot (directly snapped in) or the operation hole (lifting), which drives the baffle to move along the rounded rectangular slot and rotate around the rotation axis to achieve state switching; the whole process does not require side force application, eliminating the need for avoidance space.

[0010] Furthermore, to enable smooth rotation and position adjustment of the baffle, rotating shafts are installed on the opposite sides of the two second mounting plates, and rounded rectangular slots that are adapted to the rotating shafts are opened on both sides of the baffle. The length of the rounded rectangle is consistent with the height of the baffle, allowing the baffle to move up and down along the rotating shaft, which facilitates disengagement from or engagement with the limiting structure.

[0011] Furthermore, the bottom of each of the two second mounting plates is engaged with a first limiting post and a second limiting post, which are spaced apart along the rotation direction of the baffle. A second opening slot (adapted to the first limiting post) and a third opening slot (adapted to the second limiting post) are correspondingly opened below the baffle. When the baffle is rotated downward to the storage state, the second opening slot and the third opening slot engage with the first limiting post and the second limiting post respectively, limiting the baffle to maintain a horizontal position and preventing subsequent upward operation from being difficult due to excessive rotation. A fourth opening slot (adapted to the first limiting post) is opened below the other end of the baffle. When the baffle is rotated upward to the working state, the fourth opening slot engages with the first limiting post, limiting the baffle to maintain a vertical position and ensuring the stability of blocking goods.

[0012] Furthermore, an operating hole is provided at the front end of the baffle, which is located directly below the first opening slot. The operator can use a hook or finger to insert into the operating hole to pull the baffle, causing the baffle to move upward along the rounded rectangular slot, which facilitates quick removal from the limiting post when stored, thus improving the ease of operation.

[0013] Furthermore, all components are made of 304 or 316 stainless steel, which has high strength and corrosion resistance, meeting the needs of the airport's humid environment and heavy cargo use, and extending the service life of the baffle.

[0014] Furthermore, the inner wall of the first mounting plate is provided with a slot extending along the height direction, and the outer wall of the second mounting plate is provided with a block that matches the slot. An elastic gasket is attached to the inner wall of the slot. The elastic gasket can fill the gap between the block and the slot, enhance the stability of the connection between the two, and prevent the second mounting plate from loosening due to vibration during equipment operation.

[0015] The first limiting post distributes part of the impact force from the baffle on the rotating shaft. At the same time, the first limiting post also prevents the baffle from spontaneously tilting to the right due to the reaction force of the rotating shaft in a bumpy environment, which would cause the cargo limiting to fail. The second limiting post is also used to distribute the impact force of the baffle on the contact point between the baffle and the first mounting plate caused by the bumps when the baffle is lowered, thereby preventing the first mounting plate from being deformed by the impact.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. A concealed anti-deviation baffle device for heavy-duty logistics equipment, eliminating side space limitations: the baffle is operated from above through a first opening slot, eliminating the need to reserve clearance space on the side, adapting to compact trailers or roller conveyors, and reducing equipment installation limitations; 2. This utility model improves structural strength: by eliminating the notches on both sides of the baffle and using stainless steel, the overall strength of the baffle is significantly enhanced, which can safely block heavy loads and reduce the risk of goods slipping. 3. This utility model is reliable and convenient to operate: the combination of the limiting post and the opening slot precisely limits the storage and working position of the baffle, avoiding excessive rotation; the design of the operating hole and the rounded rectangular slot facilitates quick lifting and rotation of the baffle. 4. This utility model is easy to implement and maintain: the components are detachably connected by buckles, bolts, etc., the structure is simple and easy to process, and damaged parts can be replaced individually during later maintenance, reducing maintenance costs.

[0022] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0023] Example 1 This utility model discloses a concealed anti-deviation baffle device for heavy-duty logistics equipment, such as... Figures 1-4 As shown, the specific implementation method of this embodiment is as follows: Concealed baffle structure suitable for airport trailers In this embodiment, the concealed baffle structure is applied to an airport cargo trailer, and the specific parameters and assembly are as follows: Component dimensions and materials: First mounting plate: Made of 304 stainless steel, 250mm long, 60mm wide, and 5mm thick. The inner side wall has a 10mm wide and 3mm deep slot (extending along the height direction), and a 1mm thick silicone elastic gasket is attached to the inner wall of the slot. Second mounting plate: Made of 304 stainless steel, 200mm long, 60mm wide and 5mm thick, with an integrally formed outer wall with a 9mm wide and 8mm high clip (fitting the slot). The baffle is made of 304 stainless steel, with a length of 350mm, a width of 120mm, and a thickness of 3mm. A first opening groove with a width of 30mm and a depth of 20mm is opened at the top of one end, and an operating hole with a diameter of 20mm is opened at the front end (located directly below the first opening groove). Rounded rectangular holes with a length of 30mm and a width of 8mm are opened on both sides. Rotating shaft: Made of 304 stainless steel round shaft, 7mm in diameter and 50mm in length, it is installed on the opposite side of the second mounting plate (50mm from the top of the second mounting plate) by interference fit. The first and second limit posts are both made of 304 stainless steel cylinders, with a diameter of 6mm and a height of 15mm. They are threadedly fastened to the bottom of the second mounting plate (the distance between the two is 80mm).

[0024] Assembly process: The first mounting plate is fixed to the frame on both sides of the trailer with M8 bolts (350mm apart, parallel to the upper surface of the trailer). Insert the locking block of the second mounting plate into the locking slot of the first mounting plate, and the elastic gasket is compressed to fill the gap, thereby realizing the detachable connection between the second mounting plate and the first mounting plate. Align the rounded rectangular holes on both sides of the baffle with the rotation axis of the second mounting plate, and move the baffle downward along the axis of rotation to complete the rotational connection between the baffle and the second mounting plate. Connect the first and second limiting posts to the preset holes on the bottom of the second mounting plate to complete the overall assembly.

[0025] Operation process: Storage state: The baffle rotates downwards until the second opening slot under the baffle engages with the first limiting post and the third opening slot engages with the second limiting post. The baffle remains horizontal and is hidden under the trailer. Working state: The operator holds the first opening slot of the baffle from above, or pulls the baffle by inserting a finger into the operating hole, so that the baffle moves upward along the rounded rectangular slot (disengaging from the first and second limiting posts), and then rotates the baffle upward until the fourth opening slot at the other end of the baffle engages with the first limiting post. The baffle remains vertical and stands upright on the upper surface of the trailer, thus blocking the cargo. Reset: Reverse the above steps to switch the baffle from the working state to the storage state.

[0026] Example 2 This utility model discloses a concealed anti-deviation baffle device for heavy-duty logistics equipment, such as... Figures 1-4 As shown, the specific implementation method of this embodiment is as follows: Concealed baffle structure suitable for heavy-duty roller conveyors This embodiment is an optimization based on Embodiment 1, specifically designed for heavy-duty roller conveyors (bearing weight ≥ 500 kg). The specific improvements are as follows: Component optimization: Material upgrade: All parts are made of 316 stainless steel (more corrosion resistant, suitable for the humid working environment of roller conveyors). Enhanced strength: The baffle thickness is increased to 5mm, the diameter of the rotating shaft is increased to 10mm, and the diameters of the first and second limit posts are increased to 8mm; Operation optimization: The edge of the operating hole is integrally molded with anti-slip texture (texture depth 1mm) to prevent hand slippage when lifting; a rubber pad (thickness 2mm) is pasted on the inner wall of the first opening groove to improve operating comfort.

[0027] Adaptation and adjustments: The first mounting plate is fixed to the brackets on both sides of the roller conveyor with M10 expansion bolts (400mm spacing, to match the width of the roller conveyor). The height of the second mounting plate is increased to 250mm to ensure that the height of the goods on the roller conveyor is higher than the height of the baffle when it is erected (≥150mm).

[0028] Advantages: 1. Made of 316 stainless steel with a thickened structural design, it can withstand the impact of heavy loads of over 500kg, preventing the baffle from deforming. 2. The anti-slip texture and rubber pad design improve operational reliability in heavy-duty scenarios and reduce the labor intensity of operators.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
