Description

Technical Field

[0001] This application relates to the field of bicycle accessory technology, and in particular to a bicycle kickstand that is easy to assemble. Background Technology

[0002] Most existing bicycle kickstands maintain stability at a specific angle using a spring structure. During assembly, the spring needs to be connected to the bicycle frame and the kickstand assembly at both ends. Since the spring provides contraction force, after one end of the spring is constrained, the other end needs to be stretched using tools to overcome the spring's contraction force so that the other end can fit onto the corresponding constraint structure. This is not only laborious but also requires aligning the mating structure, making assembly quite troublesome. Utility Model Content

[0003] The purpose of this application is to provide a bicycle kickstand that is easier and quicker to assemble.

[0004] To achieve the above objectives, this application provides a bicycle kickstand that is easy to assemble: it includes a support portion, the upper end of which is fixedly connected to a configuration portion. The main body of the configuration portion is a sleeve, and the upper end of the sleeve has a pair of parallel swing blocks. The two swing blocks have coaxial shaft holes. The sleeve has a mating cavity that extends through both the upper and lower ends. The upper end of the sleeve is also provided with a limiting member. The limiting member includes a sliding post, which is adapted to be inserted into the mating cavity and forms a sliding pair with the configuration portion. A spring is provided in the mating cavity, which is adapted to provide a restoring elasticity to the limiting member. The end of the sliding post outside the mating cavity has a mating handle, which is located between the two swing blocks. When the kickstand is installed, the limiting member is first constrained, and the spring constrained by the limiting member can also remain stable during the assembly operation.

[0005] As a preferred embodiment, the main body of the support is a leg, the upper end of which is inserted into the fitting cavity and pressurized with the sleeve, requiring no welding and exhibiting high stability.

[0006] As a preferred embodiment, the outer side of the outrigger has a retaining ring, which is adapted to abut against the lower end face of the sleeve to limit the maximum mating depth between the outrigger and the sleeve.

[0007] As a preferred embodiment, the lower end of the outrigger has a footrest, and the lower surface of the footrest is fixedly connected with a pad to prevent the footrest from making direct hard contact with the ground.

[0008] As a preferred embodiment, a pad is also provided in the fitting cavity, the pad being located between the support leg and the spring to prevent direct hard contact between the spring and the end of the support leg.

[0009] As a preferred embodiment, both the gasket and the pad are made of rubber material, which has good cushioning and wear resistance properties.

[0010] As a preferred embodiment, the engagement handle has two planes that respectively engage with the two swing blocks to form a sliding pair, further suppressing the rotation of the limiting member relative to the configuration part, while improving the stability of the limiting member during movement.

[0011] As a preferred embodiment, the engagement handle is semi-circular, with a flat surface on the side facing the sliding post and an arc surface on the side facing away from the sliding post, for engagement with the arc-shaped groove on the edge of the bicycle frame's hinge.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By replacing the contraction spring with the extension spring and designing the spring inside the sleeve and constraining it by the limiting component, the spring can be stabilized by simply pressing against the limiting component during assembly so that it does not detach from the sleeve. This effectively reduces the assembly difficulty and improves the assembly efficiency. (2) By designing the support and configuration parts as a detachable structure, the support and configuration parts of various lengths can be combined to adapt to various bicycle models of different heights, thus making the bicycle kickstand more flexible in its adaptation.

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-7The bicycle kickstand shown includes a support part 1 made of alloy material. The upper end of the support part 1 is fixedly connected to a mounting part 2, which is also usually made of alloy material. The main body of the mounting part 2 is a cylindrical sleeve 201. The sleeve 201 has a mating cavity 202 that runs through both the upper and lower ends. The mating cavity 202 is also cylindrical. The sleeve 201 has a uniform wall thickness and is made of alloy material. The main body of the support part 1 is a cylindrical support leg 101. The upper end of the support leg 101 is inserted into the mating cavity 202 and is press-fitted with the sleeve 201. Therefore, even without welding, the support leg 101 is not easy to detach from the sleeve 201. The outer side of the support leg 101 has a retaining ring 102, which is used to abut against the lower end face of the sleeve 201 and limit the maximum insertion depth between the upper end of the support leg 101 and the sleeve 201.

[0026] The lower end of the outrigger 101 has a footrest 103. The footrest 103 has a larger bottom area, which can effectively distribute the pressure of the lower end of the outrigger 101 on the ground, thereby preventing the foot from sinking too deep into the mud. A pad 104 made of rubber material is fixedly connected to the lower surface of the footrest 103 to prevent the alloy outrigger 101 from making hard contact with the ground. The pad 104 is usually bonded to the bottom surface of the footrest 103 with a curing adhesive.

[0027] The upper end of the sleeve 201 has a pair of parallel swing blocks 203. The two swing blocks 203 have coaxial shaft holes 204 for the pin to pass through and cooperate with the bicycle frame to form a rotating pair. The upper end of the sleeve 201 is also provided with a limiting member 4. The limiting member 4 includes a cylindrical sliding post 401 for insertion into the fitting cavity 202 and forming a sliding pair with the configuration part 2. A spring 3 is provided in the fitting cavity 202 to provide the limiting member 4 with the return elasticity to disengage from the fitting cavity 202. A pad 5 made of rubber material is also provided in the fitting cavity 202. The pad 5 is located between the support leg 101 and the spring 3 to avoid direct hard contact between the end of the spring 3 and the end of the support leg 101. The other end of the spring 3 does not need to be provided with a pad 5 between it and the sliding post 401 because the soft and elastic pad 5 will increase the frictional resistance when the sliding post 401 moves.

[0028] The sliding post 401 has a matching handle 402 at one end outside the matching cavity 202. The end face dimension of the matching handle 402 facing the sliding post 401 is larger than the cross-sectional dimension of the sliding post 401. The matching handle 402 is located between the two swing blocks 203. The matching handle 402 has two planes, which respectively fit with the two swing blocks 203 to form a sliding pair. In this way, the limiting member 4 can only slide relative to the configuration part 2, and cannot rotate relative to the sleeve 201 because the sliding post 401 is cylindrical, which further improves the working stability of the limiting member 4. The matching handle 402 is semi-circular, with one side facing the sliding post 401 being a plane and the side facing away from the sliding post 401 being an arc surface. The arc surface is used to fit with the groove structure on the edge of the hinge frame on the bicycle frame.

[0029] Working principle: This bicycle kickstand is suitable for installation on the articulated frame of a bicycle frame. Before installation, the support part 1 and the mounting part 2 are pressed together until the bottom of the sleeve 201 abuts against the retaining ring 102. Since the support leg 101 and the sleeve 201 are interference fit, no welding is required. The fit can be kept stable under normal temperature conditions. Later, the support part 1 and the mounting part 2 can be separated by utilizing the cold contraction characteristics of metal. This design is to facilitate the replacement of the support part 1 or the mounting part 2 later. Different length combinations can be adapted to bicycles of different heights. After the support part 1 and the configuration part 2 are engaged, the lower open end of the sleeve 201 is blocked, so the pad 5 and the spring 3 can be pushed into the sleeve 201 in sequence. Then the limiting member 4 is inserted between the swing blocks 203, allowing the sliding column 401 to be inserted into the mating cavity 202, restricting the spring 3 in the mating cavity 202. Finally, the hinge frame on the bicycle frame slides between the two swing blocks 203, and the edge of the hinge frame abuts against the arc surface of the mating handle 402 until the shaft hole 204 is aligned with the round hole on the hinge frame. Then the pin can be passed through to engage the swing block 203 and the hinge frame to form a rotating pair. There is an arc-shaped groove at the bottom and rear of the hinge frame, which fits perfectly with the arc side of the mating handle 402. Under the constraint of the extension elastic force of the spring 3, the foot can remain stable in the downward or backward direction.
