Description

Technical Field

[0001] This utility model relates to a toy vehicle, and more particularly to a toy trailer. Background Technology

[0002] There are many types of toy trailers on the market. The most common toy trailer has a trailer attached to the back of the original vehicle body, forming a two-section structure.

[0003] Most toy trailers typically use a one-piece structure, meaning the trailer and the vehicle body are connected as one unit. This results in a relatively long overall length for toy trailers, making them inconvenient to transport and store. After children have played with them, and because the trailer cannot be disassembled, its fixed body takes up a lot of space, making it difficult to store and display.

[0004] A small number of toy trailers also use a detachable structure, usually connected with screws, which makes disassembly and assembly relatively cumbersome and affects the user experience. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a toy trailer. The trailer and the vehicle body are connected by a detachable connection structure, which is not only simple and convenient to assemble and disassemble, but also easy to store and place, saving space.

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

[0007] A toy trailer, characterized in that it includes a vehicle body, a connecting device, and a trailer, wherein the vehicle body and the trailer are connected by the connecting device;

[0008] The connecting device includes a hook, a pin, and a connecting sleeve. The hook is fixedly installed at the rear of the vehicle body, a connecting rod is fixedly installed at the bottom of the trailer, and the connecting sleeve is fixedly installed on the connecting rod.

[0009] The hook has a connecting groove and a through hole. The through hole passes through the upper and lower surfaces of the hook and is connected to the connecting groove.

[0010] The connecting sleeve has a front through hole, which extends through the connecting sleeve from top to bottom; the connecting sleeve is inserted into the connecting groove and fixedly connected with a pin, which passes through the through hole and the front through hole.

[0011] The pin end is provided with an elastic part. One end of the elastic part is connected to the end of the pin and can be elastically deformed along the radial direction of the pin. The other end is suspended and fixedly connected with a protrusion. Inclined guide slopes are formed on both the upper and lower sides of the protrusion.

[0012] The upper end of the pin is fixedly connected to a stop block; when the pin is inserted into the through hole of the hook, the stop block at the upper end of the pin abuts against the upper end surface, and the protrusion at the lower end of the pin abuts against the lower end surface for limitation.

[0013] The upper and lower surfaces of the connecting sleeve are both recessed, the recesses are connected to the front through hole, and the recesses are through the hook.

[0014] The connecting sleeve has a second connecting groove on the side facing away from the hook, and the end of the connecting rod is inserted into and fixedly installed in the second connecting groove.

[0015] The connecting sleeve has a through hole running vertically through the rear, and the end of the connecting rod has a second through hole. The connecting rod is inserted into the second connecting groove and fixedly connected by a connecting screw. The connecting screw passes through the through hole and the second through hole.

[0017] The lower surface of the connecting sleeve is fixedly connected to a second protrusion that is adapted to a hexagonal nut, and the hexagonal nut is partially embedded in the second protrusion to form a rotation limit.

[0018] The beneficial effects of this utility model are:

[0019] In this design, the toy trailer's trailer and body are connected by a detachable connection structure, allowing for easy disassembly and assembly. When children need to play, they simply need to use a pin to secure the hook and connecting sleeve to attach the trailer to the body. After the children have finished playing, the pin can be pulled out to separate the body from the trailer. The entire process is simple and convenient, and it also facilitates the storage and placement of toys, saving space. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses a toy trailer, such as Figures 1 to 7 As shown, it mainly includes a vehicle body 1, a connecting device 2, and a trailer 3. The vehicle body 1 and the trailer 3 are connected together by the connecting device.

[0030] like Figure 2 and Figure 3 As shown, the connecting device 2 mainly includes a hook 21, a pin 22 and a connecting sleeve 24. The hook 21 is fixedly installed at the rear of the vehicle body 1. The hook 21 is connected to the connecting sleeve 24 and fixed with the pin 22. The connecting sleeve 24 is then connected to the connecting rod 31 fixedly installed at the bottom of the trailer 3, so that the vehicle body 1, the connecting device 2 and the trailer 3 can be connected together.

[0031] like Figure 3 and Figure 4 As shown, one end of the hook 21 is connected to the vehicle body 1, and the other end has a connecting groove 212, which is mainly used to connect the connecting sleeve 24; a through hole 211 is opened between the upper end face 213 and the lower end face 214 of the hook 21, and the through hole 211 is connected to the connecting groove.

[0032] The connecting sleeve 24 has a front through hole 241 and a rear through hole 242, both of which pass through the connecting sleeve 24 vertically. The front through hole 241 end of the connecting sleeve 24 is inserted into the connecting groove 212. The through hole 211 on the hook 21 is aligned concentrically with the front through hole 241 on the connecting sleeve 24. Then, the pin 22 is passed through the through hole 211 and the front through hole 241 to fix the connecting sleeve 24 and the hook 21.

[0033] A connecting groove 243 is provided on the side of the connecting sleeve 24 facing away from the hook 21. The connecting groove 243 communicates with the rear through hole 242. The end of the connecting rod 31 can be inserted and fixedly installed in the connecting groove 243. The rear through hole 242 and the through hole 311 provided at the end of the connecting rod 31 are concentrically aligned. Then, the connecting screw 23 is used to pass through the rear through hole 242 and the through hole 311 to fix the connecting sleeve 24 and the connecting rod 31.

[0034] like Figure 6 As shown, an elastic part 221 is provided at the end of the pin 22. One end of the elastic part 221 is fixedly connected to the end of the pin 22 and can elastically deform along the radial direction of the pin 22 under external pressure. The other end is suspended and fixedly connected to the protrusion 222, which mainly serves as a limit. Inclined guide slopes are formed on both the upper and lower sides of the protrusion 222 to facilitate installation and disassembly.

[0035] like Figure 4 and Figure 6 As shown, a stop block 220 is fixedly connected to the upper end of the pin 22; when the pin 22 is inserted into the through hole 211 on the hook 21, the stop block 220 at the upper end of the pin 22 abuts against the upper end face 213 of the hook 21, and the protrusion 222 at the lower end of the pin 22 abuts against the lower end face 214 of the hook 21 to achieve the limiting position.

[0036] When the pin 22 is inserted into the through hole 211, the protrusion 222 is squeezed by the hole wall and undergoes elastic deformation inward. When the pin 22 passes through the through hole 211, the protrusion 222 is no longer squeezed by external force and recovers its elastic deformation, abutting against the lower end face 214 of the hook 21 to achieve a limit and prevent the pin 22 from retracting.

[0037] like Figure 7 As shown, recesses 245 are provided on both the upper surface 246 and the lower surface 247 of the connecting sleeve 24. The recesses 245 are connected to the front through hole 241 and pass through in the direction of the hook 21. The main function of the recesses 245 is to allow the pin 22 to easily separate the connecting sleeve 24 from the hook 21 without completely disengaging from the hook 21.

[0038] like Figure 5As shown, when you want to disassemble the hook 21 and the connecting sleeve 24, you only need to move the pin 22 upward until the end face of the pin 22 is flush with the surface of the recess 245, and keep the pin 22 connected to the through hole 211 of the upper end face 213 of the hook 21. This will allow you to separate the hook 21 from the connecting sleeve 24.

[0039] like Figure 4 As shown, when the connecting screw 23 is fixedly connected to the connecting sleeve 24 and the connecting rod 31, the connecting screw 23 is inserted into the through hole 242, the stop block 231 fixedly connected to the upper end of the connecting screw 23 abuts against the upper surface 246 of the connecting sleeve 24, and the lower end of the connecting screw 23 is threadedly connected to the hexagonal nut 25.

[0040] like Figure 7 As shown, a second protrusion 244 is fixedly connected to the lower surface 247 of the connecting sleeve 24. The second protrusion 244 is adapted to the hexagonal nut 25 and can limit the rotation of the hexagonal nut 25. In addition, the second protrusion 244 is in a semi-open state. When the hexagonal nut 25 is partially embedded in the second protrusion 244, it is convenient to install and remove the hexagonal nut 25.
