Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a welding-free connector for a vehicle frame. Background Art

[0002] A three-wheeled infant stroller is a vehicle used to carry infants and young children. It provides a series of conveniences and functions while on the move, helping parents to take care of their children more easily in daily life. The frame is a key component of the stroller, which includes two parts: a crossbeam and an axle, which are used to support and connect other components.

[0003] The frame connection of the existing infant tricycle stroller is to connect the crossbeam and the axle together by welding. However, since the crossbeam and the axle are welded together and cannot be disassembled, the tricycle stroller is too large, inconvenient to carry and carry, and is relatively inconvenient.

[0004] Therefore, a frame welding-free connector has been developed which can disassemble the crossbeam and axle of a three-wheeled infant stroller to facilitate its transportation and carrying. Utility Model Content

[0005] In order to overcome the shortcomings of the existing frame connection of the three-wheeled infant stroller, in which the cross beam and the axle are welded together and cannot be disassembled, resulting in the three-wheeled stroller being too large and inconvenient to transport and carry, the utility model provides a frame welding-free connector that can disassemble the cross beam and the axle of the three-wheeled infant stroller to facilitate its transportation and carrying.

[0006] The technical implementation scheme of the utility model is: a welding-free connector for a vehicle frame, comprising a connector, a crossbeam and an axle, wherein the crossbeam is clamped on the connector, and the axle is clamped between the crossbeam and the connector.

[0007] Optionally, connection holes are provided on both the front and rear sides of the connector, and the diameter of the connection holes is consistent with the diameter of the axle.

[0008] Optionally, two upper and lower snap-in grooves are provided on the crossbeam to facilitate snap-in connection with the connector.

[0009] Optionally, a threaded sleeve and a bolt are also included. The middle part of the axle is connected with a threaded sleeve, and the bolt is threadedly connected to the threaded sleeve. The bolt passes through the connector and is connected to the threaded sleeve, so that the connector is fixed to the axle.

[0010] Optionally, the bolt length is greater than the axle diameter.

[0011] Optionally, a cross groove is formed on the bolt.

[0012] The utility model has the following advantages: the utility model can disassemble the crossbeam and the axle of the infant tricycle by screwing the bolt to disengage the bolt from the threaded sleeve and then pulling the axle to disengage the crossbeam, thereby facilitating the transportation and carrying of the infant tricycle.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] A frame welding-free connector, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a connector 1, a crossbeam 2 and an axle 3. The crossbeam 2 is clamped on the connector 1, and the axle 3 is clamped between the crossbeam 2 and the connector 1. The crossbeam 2 is provided with two upper and lower clamping grooves for easy clamping with the connector 1. The connector 1 is provided with connecting holes on both the front and rear sides, and the diameter of the connecting holes is consistent with the diameter of the axle 3.

[0020] like Figure 3 and Figure 4 As shown, it also includes a threaded sleeve 4 and a bolt 5. The middle part of the axle 3 is connected with the threaded sleeve 4, and the bolt 5 is threadedly connected to the threaded sleeve 4. The bolt 5 passes through the connector 1. The length of the bolt 5 is greater than the diameter of the axle 3. A cross groove is opened on the bolt 5 for easy rotation.

[0021] When using the utility model, firstly, the connector 1 is snap-fitted with the crossbeam 2, and the hole position on the crossbeam 2 is made consistent with the position of the connecting hole of the connector 1, and then the axle 3 is passed through the connecting hole on the connector 1 to fix the crossbeam 2, and then the bolt 5 is connected with the threaded sleeve 4 to fix the connector 1 and the axle 3 to complete the frame assembly. When the infant three-wheeled stroller needs to be disassembled, the bolt 5 is screwed to disengage the bolt 5 from the threaded sleeve 4, and then the axle 3 is pulled out of the crossbeam 2, thereby achieving the effect of being able to disassemble the crossbeam 2 and the axle 3 of the infant three-wheeled stroller, and convenient for carrying and transporting.

[0022] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
