Description

Technical Field

[0001] This utility model relates to the field of children's vehicle manufacturing technology, and more specifically, it relates to an electric children's vehicle steering wheel. Background Technology

[0002] A steering wheel that can be detached from an electric stroller is not only easier to manufacture, but can also be transported in a disassembled state, reducing size and transportation costs. Therefore, this utility model proposes an electric stroller steering wheel. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an electric children's car steering wheel that is detachable and easy to install and remove.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to an electric children's vehicle steering wheel, comprising a control tube and a steering wheel body arranged coaxially. The steering wheel body includes a core column partially inserted into the control tube, an armrest ring surrounding the core column, and spokes arranged circumferentially between the armrest ring and the core column. A screw hole is formed inside the core column, and one end of the screw hole has a countersunk hole connected to it and formed on the core column. Several spokes are arranged evenly around the axis outside the countersunk hole. The sawing grooves are arranged in a ring array at intervals. The sawing grooves are opened on the core column and extend along the axial direction of the core column. A spring piece connected to the core column is formed between two adjacent sawing grooves. A locking screw that extends into the inner countersunk hole passes through the screw hole. A locking block in the shape of a frustum is threaded on the locking screw. Several limiting guide grooves arranged in a ring array around the axis are distributed around the outer wall of the locking block. The limiting guide grooves also extend along the axial direction of the locking block. A limiting guide rail provided on the spring piece is slidably connected in the limiting guide groove.

[0005] The present invention is further configured such that: the other end of the screw hole is provided with an external countersunk hole connected thereto and opened on the core column, and the rotating part of the locking screw is embedded in the external countersunk hole.

[0006] The present invention is further configured such that the locking screw is an internal hexagon screw.

[0007] The present invention is further configured such that the end of the core column facing the control tube has a guide portion.

[0008] In summary, the present invention has the following beneficial effects: The electric children's vehicle steering wheel involved in the present invention, by rotating the locking screw, causes the locking block to move upward, pushing the spring piece outward until the outer wall of the core column is in close contact with the inner wall of the control tube, thereby achieving a quick connection effect. Conversely, it can be disassembled, making disassembly and assembly convenient. The overall function is complete and the practicality is strong. Attached Figure Description

[0010] Figure 2 This is a partial structural schematic diagram of the present invention. Detailed Implementation

[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0013] Example 1

[0014] See Figure 1 and Figure 2 As shown, the electric stroller steering wheel involved in this embodiment includes a control tube 1 and a steering wheel body arranged coaxially. The steering wheel body includes a core post 2 partially inserted into the control tube 1. A handle ring 3 is provided outside the core post 2. Spokes 4 arranged in a circumferential pattern are connected between the handle ring 3 and the core post 2. A screw hole 5 is provided inside the core post 2. One end of the screw hole 5 is provided with an inner countersunk hole 6 connected to it and provided on the core post. A plurality of sawing grooves 7 are arranged in a ring array at equal intervals around the axis outside the inner countersunk hole 6. The cutting groove 7 is formed on the core column and extends along the axial direction of the core column. A spring piece (not marked) connected to the core column is formed between two adjacent cutting grooves 7. A locking screw 8 that extends into the inner countersunk hole is inserted into the screw hole 5. A locking block 9 in the shape of a frustum is threaded onto the locking screw 8. Several limiting guide grooves 10 arranged in a ring array around the axis are distributed around the outer wall of the locking block 9. The limiting guide grooves 10 also extend along the axial direction of the locking block 9. A limiting guide rail 11 provided on the spring piece is slidably connected in the limiting guide groove 10.

[0015] Furthermore, the locking screw 8 is an internal hexagon screw.

[0016] In this embodiment, in the initial state, the locking block 9 is in a rotating head position away from the locking screw 8. The core 2 on the steering wheel body can be quickly inserted into the control tube 1. Then, the locking screw 8 is driven to rotate using a tool. Due to the cooperation between the limiting guide groove 10 and the limiting guide rail 11, the locking block 9 cannot rotate around the axis. It can only move along the axial direction towards the rotating head of the locking screw 8, thereby squeezing the spring pieces outward, so that the core 2 is tensioned in the control tube 1, resulting in a tight connection between the control tube 1 and the steering wheel body.

[0017] Example 2

[0018] See Figure 1 and Figure 2 As shown, the electric children's car steering wheel involved in this embodiment is further configured based on embodiment 1, wherein the other end of the screw through hole 5 is provided with an outer countersunk hole 12 connected thereto and opened on the core post 2, and the rotating part of the locking screw 8 is embedded in the outer countersunk hole 12.

[0019] In this embodiment, the countersunk hole 12 is used to embed the rotating part of the locking screw 8.

[0020] Example 3

[0021] See Figure 1 and Figure 2 As shown, the electric children's vehicle steering wheel involved in this embodiment is further configured, based on embodiment 1, with the core column 2 having a guide portion 13 at the end facing the control tube 1.

[0022] In this embodiment, the guide portion 13 is provided to serve as an installation guide when the core post 2 is inserted into the operating tube 1.

[0023] The electric children's vehicle steering wheel involved in this utility model can be quickly connected by rotating the locking screw, which causes the locking block to move upward and push the spring piece outward until the outer wall of the core column is in close contact with the inner wall of the control tube. Conversely, it can be disassembled. It is easy to assemble and disassemble, has complete functions, and is highly practical.
