Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to a spring steel plate clamp and its application in packaging box bases. Background Technology

[0002] When transporting, storing, or displaying wheeled equipment (such as trolleys, instrument carts, furniture, etc.), it is often necessary to secure the wheels to prevent the equipment from sliding or tipping over. Existing securing methods mainly include: binding: This is cumbersome and time-consuming, requires additional tools (such as ropes and cable ties), and may damage the surface of the equipment. The securing effect depends on the operator's strength and has poor consistency; bolting: Although the securing is reliable, it usually requires complex installation steps (such as aligning the holes and tightening the bolts) or additional locking mechanisms (such as wrenches and locks), resulting in low loading and unloading efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a spring steel plate clamp and its application in packaging box bases to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spring steel plate clamp and its application in a packaging box base include a clamp body. The clamp body is provided with a groove that is adapted to and fixes a wheel. The groove is provided with an elastic opening for the wheel to be engaged or pulled out of the groove. In a static state, the diameter of the elastic opening is smaller than the diameter of the wheel. When the wheel is engaged or pulled out, the diameter of the elastic opening is elastically adjusted according to the local positional change of the wheel passing through the elastic opening.

[0006] Preferably, the clamp body includes a base plate and a buckle disposed on the base plate, the buckle groove is disposed on the buckle, and the elastic slot is opened on the top side of the buckle groove.

[0007] Preferably, the buckle is made of an arc-shaped bent plate, the two ends of which are bent to form the elastic groove, and the inner arc of the arc-shaped bent plate forms the groove wall of the buckle groove.

[0008] Preferably, the two ends of the arc-shaped bent plate extend upward and to the opposite side of the elastic groove to form a sliding guide portion, and the two sets of sliding guide portions cooperate to form a sliding guide opening that communicates with the elastic groove.

[0009] Preferably, the sliding guide section adopts an arc-shaped structure.

[0010] Preferably, fasteners are provided on the arc-shaped curved plate to limit the opening range of the elastic groove.

[0011] Preferably, the fastener includes a horizontal plate and a vertical plate connected together. The horizontal plate and the vertical plate are respectively disposed on the upper bottom side of the arc-shaped curved plate and the rear side of the arc-shaped curved plate. A limiting head is provided at the rear end of the sliding guide. A limiting opening is provided on the vertical plate for the limiting head to be inserted. A through-hole is provided at the bottom of the arc-shaped curved plate. An insert head is provided on the horizontal plate to be inserted into the through-hole.

[0012] Preferably, the substrate has a plurality of through mounting holes.

[0013] Preferably, the fixture body adopts an integrally formed structure of spring steel plate cut and bent, a rectangular part is cut on the base plate, the left and right ends of the rectangular part are bent upward to form the arc-shaped bending plate, and the bottom side of the arc-shaped bending plate is connected to the base plate and located in the cut.

[0014] A packaging box base includes the aforementioned spring steel plate clamp and a base plate, wherein the spring steel plate clamp comprises a plurality of spring steel plate clamps fixed to the top surface of the base plate.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model provides a spring steel plate clamp and its application in packaging box bases. The structure is simple and the number of parts is small. By setting an elastic slot, the diameter of the slot is smaller than the diameter of the wheel when stationary. However, during the process of the wheel being inserted or removed, the elastic slot can elastically deform and expand according to the local size of the wheel, allowing the wheel to pass smoothly. The loading and unloading process does not require tools, does not require alignment with complex holes, and does not require additional locking action. Simply align the wheel with the elastic slot and apply a certain pressure to insert it, or apply a pulling force to pull it out. This greatly simplifies the operation steps and significantly improves loading and unloading efficiency.

[0017] 2. This utility model provides a spring steel plate clamp and its application in a packaging box base. After the wheel is fully engaged in the slot, the elastic groove automatically retracts under the elasticity of the material, restoring its diameter to a state smaller than the wheel's diameter, thus forming a self-locking clamp on the wheel. This elastic clamping force effectively prevents the wheel from accidentally rolling or coming out during transportation or storage, providing a stable and reliable fixing effect.

[0018] 3. This utility model provides a spring steel plate clamp and its application in packaging box base. The deformable characteristics of the elastic groove allow it to adapt to wheels within a certain diameter range. As long as the wheel diameter is larger than the stationary groove size, it can be effectively clamped. There is no need to customize special clamps for each size of wheel, which improves the versatility of the product.

[0019] 4. This utility model provides a spring steel plate clamp and its application in the packaging box base. The elastic groove extends and enlarges the sliding guide, which can effectively guide the wheel into the elastic groove, reducing the requirements for operational precision, making loading and unloading smoother, and reducing the risk of scratching the wheel surface.

[0020] 5. This utility model provides a spring steel plate clamp and its application in packaging box bases. The one-piece molding structure design of the clamp body reduces manufacturing processes and assembly costs. The cost of the steel plate material itself is controllable, and due to its high durability, it reduces maintenance and replacement costs during long-term use.

[0021] 6. This utility model provides a spring steel plate clamp and its application in a packaging box base. Multiple spring steel plate clamps fixed on the base plate can quickly and reliably secure the wheels of wheeled equipment. This effectively prevents the equipment from shifting or tipping over during transportation and storage, greatly simplifies the process of loading and unloading equipment from the base, improves logistics efficiency, and provides a stable, reusable structure suitable for turnover scenarios.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Example 1

[0028] Please refer to Figures 1 to 3As shown, this utility model discloses a spring steel plate clamp, including a clamp body, the clamp body including a base plate 1 and a buckle 2 disposed on the base plate 1. The buckle 2 is provided with a groove 21 that is adapted to and fixes the wheel. The groove 21 is provided with an elastic slot 211 for the wheel to be inserted into or pulled out of the groove. In the static state, the diameter of the elastic slot 211 is smaller than the diameter of the wheel. When the wheel is inserted into or pulled out, the diameter of the elastic slot 211 is elastically adjusted according to the local position size change of the wheel passing through the elastic slot 211. The elastic slot 211 is opened on the top side of the groove 21 to facilitate the wheel to be inserted and fixed or pulled out by applying pressure.

[0029] The buckle 2 uses an arc-shaped bent plate. The two ends of the arc-shaped bent plate are bent together to form an elastic groove 211, and the inner arc of the arc-shaped bent plate forms the groove wall of the slot 21.

[0030] Both ends of the curved plate extend upwards and to the opposite side of the elastic groove 211 to form a sliding guide 22, which has an arc-shaped structure. The two sets of sliding guides 22 cooperate to form a sliding guide opening 221 that communicates with the elastic groove 211, which can effectively guide the wheel into the elastic groove 211, reduce the requirements for operational precision, make loading and unloading smoother, and reduce the risk of scratching the wheel surface.

[0031] When stationary, the diameter of the elastic slot 211 is smaller than the wheel diameter. However, during the wheel's insertion or removal, the slot can elastically deform and expand according to the local dimensions of the wheel, allowing the wheel to pass smoothly. The elastic slot 211 automatically retracts under the elasticity of the material, restoring its diameter to a state smaller than the wheel diameter, thus forming a self-locking clamp on the wheel. The loading and unloading process requires no tools, no alignment with complex holes, and no additional locking action; simply align the wheel with the guide slot 221 and apply a certain pressure to insert it, or apply a pulling force to pull it out.

[0032] Fasteners 3 are provided on the curved plate to limit the opening range of the elastic groove 211. The fasteners 3 include a horizontal plate 31 and a vertical plate 32 connected to each other. The horizontal plate 31 and the vertical plate 32 are respectively parallel and attached to the upper bottom side and the rear side of the curved plate. The rear end of the sliding guide 22 extends to provide a limiting head 23. The vertical plate 32 has a limiting opening 321 for the limiting head 23 to be inserted. The bottom of the curved plate is provided with a vertically penetrating insertion entrance 24. The horizontal plate 31 is provided with an insertion head 311 that is inserted into the insertion entrance 24. Two sets of limiting heads 23 on the curved plate respectively engage with two sets of limiting openings 321 on the fastener 3, thereby limiting the opening range of the elastic groove 211. This prevents excessive squeezing force when the wheel enters or exits, which could cause excessive deformation of the elastic groove 211 and prevent it from returning to its original position. Simultaneously, it prevents the wheel from moving back and forth within the groove 21 during transportation, thus preventing the elastic groove 211 from growing and the wheel from slipping out. The length and width of the limiting opening 321 are greater than the length and width of the limiting head 23, facilitating installation and creating a buffer space to eliminate impact stress. The insert head 311 on the horizontal plate 31 is inserted into the insert opening 24 to enhance the installation firmness of the fastener 3, preventing the wheel from swaying and impacting the vertical plate 32 of the fastener 3, thus preventing the limiting head 23 from disengaging from the limiting opening 321.

[0033] The substrate 1 is provided with several through mounting holes 11, which facilitates the substrate 1 to be firmly installed onto the base plate 4 of the packaging box base by means of bolts, rivets or welding.

[0034] The fixture body is a one-piece molded structure made of spring steel plate that has been cut and bent. A rectangular portion is cut into the base plate 1, and the left and right ends of the rectangular portion are bent upward to form arc-shaped plates. The bottom side of the arc-shaped plates is connected to the base plate and located within the cut opening 12. Spring steel plate has excellent elasticity, strength and toughness, and can withstand repeated elastic deformation and large load impacts. It has good fatigue resistance and long service life, which is far superior to non-metallic fixtures such as plastic fixtures.

[0035] Example 2

[0036] Please refer to Figures 1 to 3 As shown, this utility model discloses a packaging box base, including several spring steel plate clamps as described in Embodiment 1, and a base plate 4. The spring steel plate clamps are fixed to the top surface of the base plate 4 by means of bolts, rivets, or welding. The multiple spring steel plate clamps work together to quickly and reliably fix the wheels of the pulley device.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
