Description

Technical Field

[0001] This utility model relates to the field of helmet storage technology, and in particular to a helmet storage and transport rack. Background Technology

[0002] Motorcycle helmets are essential safety gear for riders. In motorcycle dealerships, racetracks, large-scale event support, and group riding activities, it is often necessary to centrally store, display, or transport large quantities of helmets to designated areas. Helmet storage and transport racks are typically used for the orderly storage and convenient bulk movement of motorcycle helmets.

[0003] Existing transport racks for such scenarios mostly employ simple shelf or hook structures. However, due to their unique structure, weight distribution, and smooth outer shell, motorcycle helmets present significant defects and safety hazards when transported using existing methods.

[0004] This is primarily because motorcycle helmets are generally streamlined spherical with a smooth outer surface, and their center of gravity is usually located in the upper middle part of the helmet. When the helmet is only supported at the bottom or chin, the contact area between it and the frame is small, resulting in limited friction. When the transport frame moves, turns, or brakes, the overturning moment generated by the helmet's inertia makes it very easy for it to roll or flip around its support point, especially tending to flip backward. Therefore, considering the physical characteristics of motorcycle helmets and the dynamic needs of transport scenarios, there is an urgent need for a transport frame that can effectively prevent them from flipping over during movement. Utility Model Content

[0005] The purpose of this invention is to provide a helmet storage and transport rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A helmet storage transport frame includes a transport frame body, on which several layers of base rods are fixedly installed along its length. The two ends of two base rods are fixedly connected by a crossbar. A rotating seat rod is fixedly installed above the base rods. A pair of locking components are rotatably provided at both ends of the rotating seat rod. Each locking component is located between two rotating seat rods. The side wall of the helmet visor abuts against the locking component, and the locking component supports and limits the side wall of the visor.

[0008] Preferably, the height of the base rod and the rotating seat rod are the same, the height of the locking component and the rotating seat rod are the same, the locking component follows the rotating seat rod and is higher than the base rod, and the distance between the two locking components is less than the distance between the two base rods.

[0009] Preferably, the locking assembly includes a rotating rod rotatably mounted between two rotating rods, with the sidewall of the helmet's visor abutting against the rotating rod.

[0010] Preferably, a plurality of stop bars are fixedly installed on the rotating rod by threads, and the stop bars are arranged in an L-shape.

[0011] Preferably, both ends of the rotating rod pass through the rotating seat rod, one end of which is fixedly connected to a handle, and several pairs of damping columns are fixedly installed on the rotating seat rod and the main body of the frame.

[0012] Preferably, a limit nut is threadedly installed on the outer side of the rotating rod away from the handle.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. By using an L-shaped stop that can rotate around the rotating rod, the helmet can be flipped from the inside of the visor opening to the inside of the chin opening at the bottom of the helmet, thereby blocking the side wall of the chin opening from the inside, limiting the helmet's freedom to flip backward, and preventing the helmet from falling backward from the frame body due to inertia or bumps during transportation.

[0015] 2. By designing the distance between the rotating rods of the two locking components to be less than the distance between the two bottom rods, the front end of the helmet can naturally tilt downwards after being placed under gravity. This not only makes the helmet's center of gravity more stable and easier to pick up, but also allows the side wall of the visor to naturally rest against the rotating rod, achieving rapid and automatic initial positioning of the helmet and ensuring neat storage.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] A helmet storage rack, such as Figures 1-5 As shown, the system includes a transport frame body 2, on which several layers of base rods 3 are fixedly installed along its length. Two base rods 3 are symmetrically arranged in each layer. The outer side of the helmet base rests on the base rod 3. The two ends of the two base rods 3 are fixedly connected by crossbars 5, forming a multi-layered frame structure. This creates a stable frame that can accommodate multiple rows of helmets. By bringing the front faces of two rows of helmets close together, space utilization is optimized, resulting in neat and orderly helmet storage and easy retrieval. A rotating seat rod is fixedly installed above the base rods 3. 4. A pair of locking components 1 are rotatably installed at both ends of the rotating seat rod 4. Each locking component 1 is located between the two rotating seat rods 4. The side wall of the helmet's visor abuts against the locking component 1. The locking component 1 not only provides lateral support for the side wall of the visor, helping the helmet to maintain an upright posture and ensuring neat storage, but it can also serve as a limiting mechanism. When the transport frame body 2 moves and generates vibration or inertia, it can limit the tendency of the helmet to tilt outward or slip. Several universal wheels are installed at the bottom of the transport frame body 2, which improves the flexibility of the entire transport frame.

[0027] The base rod 3 and the rotating seat rod 4 are at the same height, as are the locking components 1 and the rotating seat rod 4. The locking components 1 follow the rotating seat rod 4 and are higher than the base rod 3, and the distance between the two locking components 1 is less than that between the two base rods 3. Through this specific dimensional matching, when the bottom of the helmet is placed on the base rods 3 on both sides, the overall posture of the helmet will be affected by gravity, and its front end will naturally tilt downwards. On the one hand, this shifts the center of gravity of the helmet inwards, making the storage state more stable and also making it easier for the operator to observe and retrieve it. On the other hand, it causes the visor of the helmet to tilt downwards and naturally and reliably rest against the locking components 1 below, achieving automatic positioning and locking of the helmet without the need for additional fixing actions.

[0028] The locking assembly 1 includes a rotating rod 11 rotatably mounted between two rotating seat rods 4. The side wall of the helmet visor abuts against the rotating rod 11. When placing the helmet, the base rod 3 supports the helmet base, while the side wall of the helmet visor rests against the rotating rod 11. The rotating rod 11 and the bottom base rod 3 work together to form a two-point support, achieving the initial positioning and placement of the helmet, so that the helmet can be stably placed on the transport frame body 2.

[0029] Several stop bars 12 are fixedly installed on the rotating rod 11 by threads. The stop bars 12 are set in an L shape. When the helmet is placed, its visor opening abuts against the rotating rod 11 due to gravity. At this time, the rotating rod 11 can be rotated, which will drive all the L-shaped stop bars 12 installed on it to flip synchronously. The L-shaped structure of the stop bar 12 allows it to extend into the internal space of the helmet. Its bottom end, which was initially located inside the visor opening, flips to the inside of the chin opening at the bottom of the helmet. At this time, the bottom end of the L-shaped stop bar 12 forms a hook, blocking the side wall of the chin opening from the inside. This can effectively prevent the helmet from tilting backward due to movement and bumps, and prevent the helmet from falling off the outside of the frame body 2.

[0030] Both ends of the rotating rod 11 pass through the rotating seat rod 4, with a handle 13 fixedly connected to one end, providing a force point for the operator. By rotating the handle 13, the overall movement of the rotating rod 11 and the stop rod 12 can be controlled. Several pairs of damping columns 6 are fixedly installed on the rotating seat rod 4 and the frame body 2. The damping layer on the surface of the damping column 6 generates friction with the side wall of the handle 13. When the handle 13 is rotated to a specific angle, its side wall will be clamped between a pair of damping columns 6, and temporary positioning is achieved by using friction. This damping engagement can effectively prevent the handle 13 from rotating on its own due to slight collisions or vibrations, ensuring that the locking component 1 is in a stable open state when storing the helmet, and in a reliable locked state after locking, avoiding incorrect rotation and improving the convenience and safety of operation.

[0031] A limit nut 7 is threadedly installed on the outer side of the rotating rod 11 away from the handle 13. The limit nut 7 and the handle 13 limit the sliding of the rotating rod 11 from both ends to prevent it from falling off. When it is necessary to change the locked state, the operator first needs to pull the handle 13 outward along the axis of the rotating rod 11. This axial movement causes the side wall of the handle 13 to disengage from the pair of damping posts 6, thereby releasing the previous damping jamming state. Then the handle 13 can be rotated freely, which in turn drives the rotating rod 11 and the stop lever 12 to rotate, realizing the switching of the stop lever 12 between the locked position and the unlocked position.

[0032] The working principle of the helmet storage and transport rack provided by this utility model is as follows:

[0033] First, gently pull the handle 13 outward along the axis of the rotating rod 11 to disengage it from the damping engagement of the pair of damping posts 6. Then, rotate the handle 13 to rotate the rotating rod 11 and its L-shaped stop bar 12 to the open position. Subsequently, push the handle 13 in the opposite direction along the axis of the rotating rod 11 so that its side wall is locked by another pair of damping posts 6, temporarily fixing the locking assembly 1 in the open state.

[0034] At this point, place the outer bottom of the helmet on the two symmetrical base bars 3 and insert the visor opening into the stop bar 12. Since the distance between the rotating rods 11 of the two locking components 1 is less than the distance between the two base bars 3, the helmet will naturally form a stable posture with the front end tilted downward under the action of gravity. This posture allows the side wall of the visor opening of the helmet to naturally abut against the rotating rod 11 in the open position, thus completing the initial placement and positioning of the helmet.

[0035] After all helmets are placed, the operator pulls and turns handle 13 again. The rotation of lever 11 causes all L-shaped stops 12 to flip simultaneously. The L-shaped bottom of the stop 12 flips down from the inside area of ​​the helmet's visor opening to the inside of the chin opening at the bottom of the helmet, blocking the side wall of the chin opening from the inside. At this time, even if the transport frame shakes or bumps during movement, the helmet cannot flip backward or fall off the transport frame body 2. The bottom bar 3 prevents the helmet from falling, while the stop 12 prevents the helmet from flipping backward. Together, they achieve comprehensive restraint on the helmet.

[0036] Once locked, the entire transport frame can be moved flexibly using the casters at its bottom. When the helmet needs to be retrieved, simply reverse the locking operation: pull and reverse the handle 13 so that the lever 12 turns from the chin opening back to the mask opening area, and the helmet can be lifted directly upwards.

[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 equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
