Detailed Implementation

[0032] 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.

[0033] This embodiment discloses a children's metal tube car head assembly, which is generally used in conjunction with a children's metal tube car, such as... Figures 1-8 As shown, it mainly includes a cover 1, a hood 2 and an opening and closing structure 3. A storage slot 11 is opened on the top of the cover 1, which can be used to place items. The hood 2 is fastened to the top of the storage slot 11, and its rear end is rotatably connected to the cover 1. The front end can be opened and closed relative to the storage slot 11. The opening and closing structure 3 is installed at the front end of the cover 1, which is mainly used to lock the hood 2.

[0034] like Figure 6 , Figure 7 and Figure 8As shown, the opening and closing structure 3 mainly includes a movable block 31, a second spring 32, and a fixed block 33. The fixed block 33 is fixedly installed on the cover 1. The movable block 31 connects the latch 312, the button 311, and the sleeve rod 314 together through the connecting part 313. The latch 312 and the button 311 are connected to the front end of the connecting part 313 on the same side, while the sleeve rod 314 is connected to the rear end of the connecting part. The movable block 31 is slidably connected to the fixed block 33 through the sleeve rod 314. The second spring 32 is fitted on the sleeve rod 314. The front end of the second spring 32 elastically abuts against the connecting part 313 on the movable block 31, pushing the movable block 31 forward, while the rear end abuts against the fixed block 33 and is limited.

[0035] like Figure 3 As shown, the front end of the hood 2 is integrally connected to the card block 21. A card slot 22 is provided above the card block 21. The card head 312 on the movable block 31 can be inserted into the card slot 22 and engage with the card block 21, so that the hood 2 can be firmly fastened to the upper end of the cover body 1.

[0036] like Figure 3 and Figure 5 As shown, a limiting groove 12 is provided at the front end of the inner side of the cover 1. The limiting groove 12 is adapted to the movable block 31. The movable block 31 can be embedded in the limiting groove 12 and can slide relative to it.

[0037] like Figure 5 As shown, fixing posts 16 are integrally connected to both sides of the limiting groove 12 inside the cover 1. The fixing block 33 has a through limiting hole 331 in the center and through positioning holes 332 at both ends. The fixing block 33 is placed behind the limiting groove 12, the movable block 31 is locked inside the limiting groove 22, the sleeve rod 314 is inserted into the limiting hole 331, and the fixing posts 16 on both sides of the limiting groove 12 are inserted into the positioning holes 332 and connected with screws to realize the fixed installation of the fixing block 33. The installation process is convenient and easy to disassemble and maintain.

[0038] like Figure 5 and Figure 6 As shown, an upper through hole 13 is opened above the baffle 15 at the front end of the limiting groove 12, and the clip 312 can be inserted into the upper through hole 13. A lower through hole 14 is opened below the baffle 15, and the button 311 can be inserted into the lower through hole 14. Under the elastic pressure of the second spring 32, the connecting part 313 abuts against the baffle 15.

[0039] When the button 311 on the movable block 31 is pressed, the second spring 32 is compressed and the movable block 31 can move horizontally backward, so that the locking head 312 disengages from the locking slot 22, and the locking block 21 and the locking head 312 no longer abut against each other, thus opening the hood 2. After the button 311 is released, the movable block 31 is pushed back to its original position under the elastic force of the second spring 32.

[0040] like Figure 6As shown, the clip 312 has a guide slope and the guide slope faces forward. When the hood 2 is fastened, the guide slope abuts against the clip 312, and the movable block 31 compresses the second spring 32 and moves backward, so that the clip 312 can be inserted into the clip slot 22. The clip 312 abuts against the clip 21, thereby achieving the fastening of the hood 2.

[0041] like Figure 6 As shown, a positioning groove 18 is provided at the upper end of the cover 1, and a first spring 17 is installed in the positioning groove. The upper end of the first spring 17 can elastically resist the inside of the hood 2, and the lower end is locked inside the positioning groove 18. When the button 311 is pressed, the locking head 312 and the locking block 21 are no longer locked. Under the elastic force of the first spring 17, the hood 2 is lifted up, making it easy to lift the hood 2 by hand.

[0042] Example 2

[0043] This embodiment discloses a children's metal pipe car head assembly, based on Embodiment 1, and further referring to Figure 1. Figure 9 , Figure 10 , Figure 11 Please provide an explanation.

[0044] In Example 1, refer to Figure 1 , Figure 2 As shown, button 311 passes through the lower through hole 14, and the end of button 311 protrudes from the outside of the front assembly, allowing it to be easily pressed with a finger.

[0045] In this embodiment, refer to Figure 9 , Figure 10 and Figure 11 As shown, button 311 extends into the lower through hole 14. The end of button 311 is not exposed on the outside of the front assembly, but remains in the lower through hole 14. When pressing button 311, a tool can be inserted into the lower through hole 14 to press button 311. This prevents accidental activation during operation and also avoids button 311 being directly exposed outside the front of the vehicle, maintaining the uniformity of the overall shape and color of the front of the vehicle.
