Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, specifically an adjustable automotive parts storage rack. Background Technology

[0002] Automotive parts storage racks improve space utilization through standardized storage, protect parts from damage, facilitate management and retrieval to improve efficiency, ensure operational safety, and adapt to different scenario requirements. They are an important tool for all links in the automotive industry chain to achieve standardized management of parts, reduce costs and increase efficiency, and ensure safety.

[0003] In the prior art, a car parts storage rack with publication number "CN214293081U" includes a base. Universal wheels are fixedly connected to the corners of the bottom of the base. A push-pull rod is rotatably connected to one side of the top of the base. A fixed frame is fixedly connected to the top of the base away from the push-pull rod. A top plate is welded to the top of the fixed frame. A receiving groove is formed on the inner surface of the rear end of the fixed frame. Multiple first placement plates are rotatably connected to the inner walls of both sides of the fixed frame. Second placement plates are slidably connected to the inner sides of the multiple first placement plates. In this invention, the universal wheels and push-pull rod allow for more convenient transfer of car parts. The first placement plates can be rotated via a pivot, thereby storing them in the receiving groove and reducing space occupation. The second placement plates can slide inside the first placement plates, and the distance the second placement plates can be pulled out can be adjusted by adjusting the buckles, reasonably expanding the available space.

[0004] However, existing technologies still have significant shortcomings, such as: Most storage racks have fixed spacing between their load-bearing structures, which cannot be flexibly adjusted according to the width of the parts. For parts of different specifications, either the spacing is too wide, causing the parts to shake, or the spacing is too narrow, making it difficult to place them. This results in limited adaptability and poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable automotive parts storage rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable car parts storage rack includes a base with several casters fixedly mounted on it. Two symmetrical guide rods are also fixedly mounted on the base, and several sliding rods are slidably mounted on the guide rods. A shearing mechanism is mounted on the base, with its central hinge point rotatably connected to the sliding rods. One end of the shearing mechanism is rotatably connected to the base. Through the linkage of the shearing mechanism, one of the sliding rods is pushed to slide, and the remaining sliding rods slide along the guide rods at the same distance. A support frame is fixedly installed on the sliding rod.

[0007] Preferably, V-shaped support plates are fixedly provided at both ends of the support frame.

[0008] Preferably, elastic pads are fixedly provided on the side walls of the V-shaped support plate and the support frame.

[0009] Preferably, a threaded rod is rotatably mounted on the base, and a nut is rotatably mounted at an intermediate hinge point of the shearing mechanism, the nut engaging with the threaded rod.

[0010] Preferably, a handwheel is fixedly provided at one end of the threaded rod.

[0011] Preferably, a pull rod is fixedly installed on the base.

[0012] Preferably, the pull rod is fixedly provided with a plurality of handles, and the handles are provided with anti-slip textures.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This device uses a handwheel to drive a threaded rod, which extends and retracts via a nut-linked shearing mechanism. This causes the sliding rod to move synchronously and equidistantly along the guide rod, thus adjusting the spacing of the V-shaped support plates. It can both widen the spacing to accommodate wider cylindrical parts and narrowen the spacing to clamp narrower parts, effectively adapting to the storage and transportation needs of parts with different widths and solving the problems of fixed width and poor adaptability of traditional storage racks.

[0014] 2. The V-shaped support plates at both ends of the support frame form a limiting structure with the contact surface of the parts. Combined with the clamping force generated by the contraction of the shearing mechanism, the parts can be stably fixed and prevented from rolling or shifting during movement. The elastic pads on the inner surface of the V-shaped support plate and the side wall of the support frame can buffer rigid collisions, avoid scratches on the surface of the parts, and increase friction to further improve storage stability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: This adjustable automotive parts storage rack uses a base 1 as its load-bearing component, providing basic support for the entire device. At the bottom of the base 1, several casters 11 are fixedly installed using welding or bolt connections. These casters 11 support flexible movement of the device on the ground, and each caster 11 is equipped with a locking function, similar to a common brake mechanism. When storing or transporting automotive parts, operators can control the locking function of the casters 11 to ensure the device is stably parked in the designated position, preventing unnecessary displacement and thus ensuring the stability of the device and the automotive parts it carries during operations.

[0019] Two guide rods 12 are fixedly installed symmetrically along the horizontal direction on the upper surface of the base 1. The main function of the guide rods 12 is to provide guidance for the sliding rod 13.

[0020] Multiple sliding rods 13 are mounted on the guide rod 12 via a sliding fit. The sliding rods 13 are perpendicular to the guide rod 12 and can slide freely along the length of the guide rod 12. During the width adjustment process, the sliding rod 13 acts as the actuator for the width adjustment. When acted upon by the shearing mechanism 14, it slides along the guide rod 12, thereby changing the position of the support frame 15 on the sliding rod 13. This achieves width adjustment of the device. Its working principle utilizes the sliding fit between the sliding rod 13 and the guide rod 12 to convert the power transmitted from the shearing mechanism 14 into horizontal displacement of the sliding rod 13, thus realizing the width adjustment function and providing a foundation for adapting to automotive parts of different widths.

[0021] On the base 1, there is a shearing mechanism 14 consisting of multiple sets of cross-arranged and hinged connecting rods. The two ends of each connecting rod are connected to the adjacent connecting rods through hinge points. This connection method allows multiple sets of connecting rods to work together to form a linkage structure that is similar to the opening and closing of scissors and can perform telescopic movements.

[0022] The hinge point located in the middle of the shearing mechanism 14 is rotatably connected to the sliding rod 13. The hinge point near one end of the base 1 is also rotatably connected to the base 1. When an external force is applied to the shearing mechanism 14, causing it to extend or retract, the linkage between the hinge points pushes one of the sliding rods 13, causing it to slide along the length of the guide rod 12. The remaining sliding rods 13, constrained by the linkage of the shearing mechanism 14, slide synchronously and at equal intervals, following the pushed sliding rod 13.

[0023] The shearing mechanism 14 utilizes a telescopic structure formed by the hinged linkages of the connecting rods to convert the applied external force into the translational motion of the sliding rods 13. By sliding multiple sets of sliding rods 13 synchronously and at equal intervals, the horizontal distance between the sliding rods 13 and between them and the related structures of the base 1 is changed, thereby achieving equidistant adjustment of the device's width. This width adjustment function can accommodate cylindrical automotive parts of different widths, providing a structural basis for the stable clamping and transportation of these parts, ensuring that the device can effectively bear the load regardless of changes in the width of the parts.

[0024] A support frame 15 is fixedly installed on the sliding rod 13 by welding. The support frame 15 extends along the length of the sliding rod 13 and is used to support cylindrical automotive parts. When the sliding rod 13 slides on the guide rod 12 to adjust its width, the support frame 15 moves synchronously with the sliding rod 13 to accommodate the placement requirements of parts of different widths.

[0025] At both ends of the support frame 15, V-shaped support plates 16 are fixed by welding or bolting. The openings of the V-shaped support plates 16 face upwards, and together with the support frame 15, they form a clamping structure for cylindrical parts. When cylindrical parts are placed on the support frame 15, the V-shaped support plates 16 can limit the parts from both sides to prevent them from rolling or shifting.

[0026] Elastic pads 17 are adhered to the inner surface of the V-shaped support plate 16 and the side wall of the support frame 15. These elastic pads 17 can be made of materials with cushioning properties, such as rubber. When cylindrical components come into contact with the V-shaped support plate 16 and the support frame 15, the elastic pads 17 buffer the impact force, preventing damage to the component surfaces due to rigid contact. Simultaneously, the elastic pads 17 increase the friction between the components and the support, further enhancing the stability of the components during storage and transportation, preventing slippage or drops. The working principle utilizes the physical properties of the elastic pads 17 to convert mechanical energy (impact force) into elastic deformation energy, protecting the components and enhancing the reliability of clamping, ensuring that cylindrical components can be stably placed on the device, adapting to subsequent handling and storage processes.

[0027] A rotating threaded rod 18 is mounted on the base 1 via a bearing in a horizontal direction. One end of the threaded rod 18 extends to the outside of the base 1, and a handwheel 20 is fixedly mounted at that end, allowing the operator to drive the threaded rod 18 to rotate by turning the handwheel 20.

[0028] At an intermediate hinge point of the shearing mechanism 14, a nut 19 is mounted via a rotating connection structure. The nut 19 cooperates with the threaded rod 18 to form a lead screw nut 19 transmission pair.

[0029] When the operator turns the handwheel 20, the handwheel 20 drives the threaded rod 18 to rotate. Due to the threaded engagement between the nut 19 and the threaded rod 18, the rotation of the threaded rod 18 causes the nut 19 to move along the axial direction of the threaded rod 18. The nut 19 is connected to the intermediate hinge point of the shearing mechanism 14, and its axial movement applies a force to the shearing mechanism 14, thereby causing the shearing mechanism 14 to undergo telescopic deformation. When it is necessary to widen the device to accommodate wider parts, the operator turns the handwheel 20 forward, and the threaded rod 18 rotates forward accordingly, causing the nut 19 to move along the axial direction of the threaded rod 18 away from the base 1. At this time, the shearing mechanism 14 is pulled (or pushed) by the nut 19 and unfolds. The unfolding action of the shearing mechanism 14 will push the sliding rod 13 connected to it to slide outward along the guide rod 12, thereby increasing the distance between the sliding rods 13 and providing sufficient space for the wide parts to be placed. When it is necessary to reduce the width of the device to clamp the parts, the operator turns the handwheel 20 in the opposite direction, the threaded rod 18 rotates in the opposite direction, and drives the nut 19 to move along the axial direction of the threaded rod 18 towards the center of the base 1. The shearing mechanism 14 is contracted by the force of the nut 19. The contraction of the shearing mechanism 14 will pull the sliding rod 13 to slide inward along the guide rod 12, so that the distance between the sliding rods 13 is reduced, thereby realizing the clamping operation of the parts placed on the support frame 15 and preventing the parts from shifting during transportation and storage.

[0030] An inclined pull rod 21 is fixedly installed on the base 1 by welding. The pull rod 21 extends along the length of the base 1, and its height and position are designed according to the natural posture of the operator when pushing or pulling, so as to facilitate the application of pushing or pulling force.

[0031] Multiple rubber handles 22 are mounted on the lever 21, and the surface of the handles 22 is machined with anti-slip textures 221. The anti-slip textures 221 can increase the friction between the hand and the handles 22, prevent the hand from slipping during pushing and pulling, and improve the stability of operation.

[0032] When the device needs to be moved, the operator holds handle 22 and transmits pushing or pulling force to base 1 through lever 21. The casters 11 at the bottom of base 1 roll under the force and can turn flexibly, allowing the device to move in any direction to meet the needs of moving to different work positions in the workshop.

[0033] Once the device is moved to the target working position, the operator operates the locking mechanism of the caster wheel 11 (such as by pressing the brake pedal) to stop the caster wheel 11 from rolling. The device can then be stably stopped at that position, preventing displacement during subsequent loading and unloading of parts or adjustment of width, thus ensuring the stability of the operation process.

[0034] Working Principle: During use, the operator drives the threaded rod 18 to rotate by turning the handwheel 20. Since the threaded rod 18 and the nut 19 at the hinge point of the shearing mechanism 14 form a threaded engagement, the rotation of the threaded rod 18 is converted into axial translation of the nut 19, thereby causing the shearing mechanism 14 to extend and retract. The extension and retraction of the shearing mechanism 14, through its rotational connection with the sliding rod 13, pushes multiple sets of sliding rods 13 to move synchronously and equidistantly along the guide rod 12, causing the support frame 15 fixed on the sliding rod 13 and the V-shaped support plates 16 at both ends to change their spacing accordingly.

[0035] When clamping parts, the shearing mechanism 14 is unfolded by adjusting the handwheel 20, the distance between the sliding rods 13 is increased, and the space between the V-shaped support plates 16 is expanded, making it easier to place cylindrical parts of different widths onto the support frame 15; after the parts are placed in place, the handwheel 20 is rotated in the opposite direction to retract the shearing mechanism 14, the distance between the sliding rods 13 is reduced, and the V-shaped support plates 16 approach and clamp the parts from both sides to achieve stable fixation.

[0036] During the process, the elastic pads 17 on the inner surface of the V-shaped support plate 16 and the side wall of the support frame 15 come into contact with the surface of the parts. Through their own deformation, they buffer rigid collisions to avoid damage to the parts, while increasing the friction of the contact surface to prevent the parts from sliding during movement. When the device needs to be moved, the operator holds the handle 22 on the pull rod 21 (the anti-slip texture 221 on the surface of the handle 22 enhances grip stability) and pushes or pulls the base 1. The casters 11 at the bottom of the base 1 roll and turn flexibly to move the device to different work areas. After reaching the target position, the casters 11 are locked to stop rolling, ensuring that the device remains stable during loading, unloading or adjustment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
