Description

Technical Field

[0001] This utility model relates to the field of parking rack technology, specifically a bicycle parking rack. Background Technology

[0002] A bicycle parking rack is a metal frame used to park bicycles, electric bikes, or motorcycles. Primarily for bicycles, its main functions are to save space, prevent bicycle theft, and maintain a clean environment. Common bicycle parking racks include spiral, slot-type, and double-layer telescopic types. These racks are usually made of materials such as carbon steel and stainless steel, which have good weather resistance and durability. Most household bicycle parking racks are slot-type racks. This type of rack can stably hold the bicycle wheels in place, allowing for parking by supporting the wheels, and it also has a high space utilization rate.

[0003] Current bicycle racks rely solely on a single support rod and support wheel to support the bicycle wheels, resulting in insufficient actual stability. Furthermore, the support rod is limited to a torsion spring for restraint, leading to poor overall restraint. Utility Model Content

[0004] This utility model provides a bicycle parking rack, which can effectively solve the problems mentioned in the background art. Current parking racks only support the bicycle wheels through a single support rod and support wheel, resulting in insufficient actual support stability of the bicycle. Furthermore, when the support rod is used for support, only a torsion spring is set for limiting support, resulting in poor overall limiting effect of the support rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bicycle parking frame, including a connecting crossbar, on both sides of the bottom of the connecting crossbar, support rods are symmetrically welded, and anti-slip blocks are sleeved on the outer sides of the ends of the two support rods. Limiting groove blocks are detachably connected to both sides of the top of the connecting crossbar by screws, and an L-shaped mounting plate is detachably installed on one side of the top of the connecting crossbar by screws. A telescopic support rod is rotatably connected to one side of the L-shaped mounting plate, and a deflection support rod is rotatably connected to the other side of the L-shaped mounting plate.

[0006] The edge of the L-shaped plate is provided with a first limiting arc groove corresponding to the telescopic support rod, and the edge of the L-shaped plate is provided with a second limiting arc groove corresponding to the deflection support rod. A locking knob is installed on the edge of the telescopic support rod. The end of the telescopic support rod is rotatably connected to a first support wheel through a telescopic connection structure. The inner side of the end of the deflection support rod is embedded with a second support wheel.

[0007] The inner side of the L-shaped plate is connected to a connecting shaft located on one side of the deflection support rod. A support torsion spring is sleeved on the outer side of the connecting shaft. A limiting step groove is provided in the middle of the second limiting arc groove. A sleeve is embedded in the edge of the deflection support rod corresponding to the limiting step groove. A step column is slidably connected inside the sleeve. A pull block is provided at the end of the step column.

[0008] Preferably, the limiting groove block is provided with a limiting groove for limiting the wheel, and the telescopic support rod and the locking knob both slide along the first limiting arc groove. The locking knob restricts and fixes the telescopic support rod to the edge of the L-shaped plate.

[0009] Preferably, the deflection rod drives the stepped column to slide along the second limiting arc groove, and when the deflection rod deflects, it is elastically supported by a support torsion spring, the end of which is connected to the deflection rod by a pull rod.

[0010] Preferably, the second limiting arc groove is formed by combining two arc grooves, and the limiting step groove is located at the junction of the two arc grooves;

[0011] The stepped column is composed of two short columns with different diameters, and the diameters of the two short columns correspond to the two segments of the second limiting arc groove.

[0012] Preferably, a telescopic sliding hole is provided on the inner side of the end of the telescopic support rod, and an adjustable telescopic frame is slidably connected inside the telescopic sliding hole. The first support wheel is rotatably connected to the inner side of the adjustable telescopic frame, and a limit knob is connected to the edge of the telescopic support rod at the corresponding position of the adjustable telescopic frame.

[0013] Preferably, the first support wheel is rotatably connected to the inside of the adjustable telescopic frame via a movable shaft, and the limiting knob locks and restricts the position between the adjustable telescopic frame and the telescopic support rod.

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0015] 1. By installing the first limiting arc groove in the L-shaped plate, the telescopic support rod can drive the first support wheel to deflect, and the locking knob can lock and limit the telescopic support rod, thus providing initial support for the wheel. The second limiting arc groove in the L-shaped plate can facilitate the deflection of the support rod and drive the second support wheel to deflect. Under the support of the torsion spring, the deflection support rod can be initially supported and limited, thus facilitating secondary support for the wheel through the second support wheel. By rotating the first and second support wheels to fit against the edge of the bicycle wheel, effective support for the wheel is achieved, ensuring the stability of the parking frame during actual bicycle support.

[0016] 2. By using the limiting step groove in the second limiting arc groove, in conjunction with the sleeve, step column and pull block on the side of the deflection support rod, the step column can be slid by the pull block when the deflection support rod deflects, so that the short column with the corresponding large diameter can be locked on the larger diameter section of the arc groove in the second limiting arc groove. This achieves the position locking and restriction of the deflection support rod. The extension and retraction of the step column makes it easy to release the limit, making the support and limit of the deflection support rod more convenient, and at the same time making the deflection support rod more stable when supporting the wheel.

[0017] Furthermore, both the telescopic support rod and the deflection support rod can be deflected, making it easy to rotate them to a horizontal position when not in use, thereby reducing the space occupied.

[0018] 3. By opening telescopic sliding holes at the ends of the telescopic support rod, it is convenient to slide the adjustable telescopic frame and the telescopic support rod together. The first support wheel is installed on the inner side of the adjustable telescopic frame. By adjusting the extended length of the adjustable telescopic frame, the position of the first support wheel can be adjusted, making it easier for the first support wheel to support wheels of different diameters. The adjustable telescopic frame is limited to the inner side of the telescopic support rod by the limit knob, ensuring the support stability of the adjustable telescopic frame and the first support wheel after the position is adjusted.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-5 As shown, this utility model provides a technical solution for a bicycle parking rack, including a connecting crossbar 1. Support rods 2 are symmetrically welded to the bottom of both sides of the connecting crossbar 1, and anti-slip blocks 3 are sleeved on the outer sides of the ends of the two support rods 2. Limiting groove blocks 4 are detachably connected to the top of both sides of the connecting crossbar 1 by screws. An L-shaped mounting plate 5 is detachably installed on one side of the top of the connecting crossbar 1 by screws. A telescopic support rod 6 is rotatably connected to the inner side of the L-shaped mounting plate 5, and a deflection support rod 7 is rotatably connected to the other side of the inner side of the L-shaped mounting plate 5.

[0029] A first limiting arc groove 8 is provided at the edge of the L-shaped plate 5 corresponding to the telescopic support rod 6, and a second limiting arc groove 9 is provided at the edge of the L-shaped plate 5 corresponding to the deflection support rod 7. A locking knob 10 is installed on the edge of the telescopic support rod 6. The end of the telescopic support rod 6 is rotatably connected to the first support wheel 11 through a telescopic connection structure. A limiting groove for limiting the wheel is provided in the limiting groove block 4. The telescopic support rod 6 and the locking knob 10 slide along the first limiting arc groove 8. The locking knob 10 restricts and fixes the telescopic support rod 6 to the edge of the L-shaped plate 5, so that the telescopic support rod 6 can drive the first support wheel 11 to deflect. The locking knob 10 locks and limits the telescopic support rod 6, thereby providing initial support for the wheel. The inner side of the end of the deflection support rod 7 is embedded and rotatably connected to the second support wheel 12.

[0030] A connecting shaft 13 is connected to the inner side of the L-shaped plate 5, located on one side of the deflection rod 7. A support torsion spring 14 is sleeved on the outer side of the connecting shaft 13. A limiting step groove 15 is provided in the middle of the second limiting arc groove 9. A sleeve 16 is embedded in the edge of the deflection rod 7 corresponding to the limiting step groove 15. A step column 17 is slidably connected to the inside of the sleeve 16. The deflection rod 7 drives the step column 17 to slide along the second limiting arc groove 9. When the deflection rod 7 deflects, it is elastically supported by the support torsion spring 14. The end of the support torsion spring 14 is connected to the deflection rod 7 through a pull rod. The second limiting arc groove 9 in the L-shaped plate 5 facilitates the deflection rod 7 to drive the second support wheel 12. The deflection is facilitated by the support of the torsion spring 14, which provides initial support and limitation for the deflection rod 7. A pull block 18 is provided at the end of the step column 17. The second limiting arc groove 9 is formed by the combination of two arc grooves, which limits the step groove 15 to be located at the junction of the two arc grooves, thus facilitating the formation of the step groove 15. The step column 17 is composed of two short columns with different diameters, and the diameters of the two short columns are respectively equal to the two arc grooves of the second limiting arc groove 9. By pulling the step column 17 with the pull block 18, the short column with the larger diameter corresponding to the step column 17 can be locked on the arc groove with the larger diameter in the second limiting arc groove 9, thereby achieving the position locking limitation of the deflection rod 7.

[0031] A telescopic sliding hole 19 is provided on the inner side of the end of the telescopic support rod 6. An adjustable telescopic frame 20 is slidably connected inside the telescopic sliding hole 19. The first support wheel 11 is rotatably connected to the inner side of the adjustable telescopic frame 20. A limit knob 21 is connected at the corresponding position of the edge of the telescopic support rod 6 and the adjustable telescopic frame 20. The first support wheel 11 is rotatably connected to the inner side of the adjustable telescopic frame 20 through a movable shaft. The limit knob 21 locks and restricts the position between the adjustable telescopic frame 20 and the telescopic support rod 6. The limit knob 21 is used to limit the installation of the adjustable telescopic frame 20 on the inner side of the telescopic support rod 6, ensuring the support stability of the adjustable telescopic frame 20 and the first support wheel 11 after position adjustment.

[0032] The working principle and usage process of this utility model: In actual application, the bicycle parking frame first connects the support rods 2 at the bottom of both sides of the cross frame 1 to facilitate the overall support of the parking frame. Combined with the anti-slip block 3, the stability of the overall support of the parking frame is improved. When actually supporting the bicycle, the first limiting arc groove 8 in the L-shaped plate 5 is installed to facilitate the telescopic support rod 6 to drive the first support wheel 11 to deflect. The locking knob 10 locks and limits the telescopic support rod 6, thereby achieving initial support for the wheel.

[0033] Furthermore, when the first support wheel 11 supports the bicycle wheel, the telescopic sliding hole 19 at the end of the telescopic support rod 6 facilitates the sliding connection between the adjustable telescopic frame 20 and the telescopic support rod 6. The first support wheel 11 is installed on the inner side of the adjustable telescopic frame 20, thereby adjusting the position of the first support wheel 11 by adjusting the extended length of the adjustable telescopic frame 20. This allows the first support wheel 11 to be better suited for supporting wheels of different diameters. The limiting knob 21 is used to limit the adjustable telescopic frame 20 to be installed on the inner side of the telescopic support rod 6, ensuring the support stability of the adjustable telescopic frame 20 and the first support wheel 11 after position adjustment.

[0034] Meanwhile, the second limiting arc groove 9 within the L-shaped plate 5 facilitates the deflection of the deflection rod 7, which drives the second support wheel 12 to deflect. Supported by the torsion spring 14, this provides initial support and limitation for the deflection rod 7. Simultaneously, the limiting step groove 15 within the second limiting arc groove 9, in conjunction with the sleeve 16, step column 17, and pull block 18 on the side of the deflection rod 7, allows the pull block 18 to slide the step column 17 during deflection. This enables the corresponding short columns with larger diameters to be locked onto the larger diameter section of the arc groove within the second limiting arc groove 9, thus achieving position locking and limitation of the deflection rod 7. Furthermore, the extension and retraction of the step column 17 facilitates the release of the limitation, making the support and limitation of the deflection rod 7 more convenient and ensuring greater stability when supporting the wheel.

[0035] This allows for secondary support of the wheel via the second support wheel 12, and the stability of the wheel during support is ensured by the limiting groove block 4. By rotating the first support wheel 11 and the second support wheel 12 to fit against the edge of the bicycle wheel, effective support of the wheel is achieved, ensuring the stability of the parking frame during actual bicycle support. In addition, both the telescopic support rod 6 and the deflection support rod 7 can be deflected, making it convenient to rotate them to a horizontal position when not in use, thereby reducing the space occupied.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
