[0018] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] like Figures 1 to 3 As shown, the embedded pull-type vehicle hood security lock 100 of this utility model is installed on the hood of a car and locks or unlocks it. The embedded pull-type vehicle hood security lock 100 includes a base 1, a handle 2, a swing arm 3, a locking tongue 4, and an elastic reset member 5. The surface of the base 1 is provided with a receiving cavity 1a. The handle 2 is pivotally connected to the base 1 via a pivot shaft 21 and is embedded in the receiving cavity 1a. The handle 2 has a latching part 22 for hand gripping. The latching part 22 completely covers the opening 23 of the receiving cavity 1a, and the middle of the latching part 22 has an opening 23 communicating with the inside and outside of the receiving cavity 1a. The middle part of the swing arm 3 is pivotally connected to the base 1, and the pivoting center axis is perpendicular to the pivoting center axis of the handle 2. The swing arm 3 is located below the handle 2. One end of the handle 2 abuts against one end of the swing arm 3 so as to push the swing arm 3 to rotate when rotated. The latch 4 is located below the handle 2 and above the swing arm 3; the latch 4 is slidably disposed on the seat 1 with one end extending downward to abutment 41; a pushing ramp 31 is provided on one side of the swing arm 3, and the pushing ramp 31 slides against the abutment 41 so that when the swing arm 3 swings, the latch 4 is driven to retract into the seat 1 through the abutment 41. The elastic reset member 5 is disposed between the latch 4 and the seat 1 to provide an elastic force for the latch 4 to extend out of the seat 1; the elastic reset member 5 is a compression spring.

[0020] Please see again Figures 1 to 3 One end of the handle 2 is provided with a drive unit 24, one end of which bends and extends to one end of the swing arm 3, and abuts against one end of the swing arm 3. The drive unit 24 can rotate around the pivot shaft 21 following the handle 2, thereby driving the swing arm 3 to swing. By providing the drive unit 24, the rotational driving force of the handle 2 can be transmitted to the swing arm 3, thereby making the structural layout of the swing arm 3 and the handle 2 more compact and reasonable.

[0021] like Figure 4 As shown, the base 1 is provided with a mounting post 1b, and the swing arm 3 is pivotally connected to the mounting post 1b. The central axis of the mounting post 1b is coaxial with the pivoting central axis of the swing arm 3. This allows the swing arm 3 to be mounted on the lower side of the handle 2, making the overall structure more compact and smaller in size.

[0022] Please refer to Figures 1 to 3 , the lock 100 further comprises a lock cylinder 6, the lock cylinder 6 is arranged on the seat body 1, and a key hole of the lock cylinder 6 is located on the surface of the seat body 1, an output end of the lock cylinder 6 is eccentrically provided with an engaging portion 61, and one end of the swing arm 3 away from the driving portion 24 is provided with an engaging groove 32, the engaging portion 61 is engaged in the engaging groove 32 to lock the pull handle 2, or the engaging portion 61 is disengaged from the engaging groove 32 to release the pull handle 2. By arranging the lock cylinder 6 matched with the engaging groove 32 of the swing arm 3, the swing arm 3 and the pull handle 2 can be locked or released by the lock cylinder 6, so that the locking or releasing state of the pull handle 2 can be controlled, and the purpose of preventing accidental unlocking or malicious unlocking is achieved, and the effect of theft prevention is achieved.

[0023] Please refer to Figures 2 to 4 , the seat body 1 is provided with a sliding groove 1c, and the lock tongue 4 is slidingly arranged in the sliding groove 1c; and the extending direction of the sliding groove 1c is parallel to the pivot shaft 21. The sliding groove 1c can guide and limit the lock tongue 4, and the stability of the sliding of the lock tongue 4 is guaranteed. The seat body 1 comprises an upper seat 11, a lower seat 12 and a cover body 13, the lower seat 12 is arranged on the lower side of the upper seat 11, and the sliding groove 1c is arranged on the lower seat 12. The cover body 13 is arranged on the lower side of the lower seat 12. In this way, the pull handle 2, the swing arm 3 and the lock tongue 4 can be more conveniently and easily mounted into the seat body 1, and the convenience of assembly is improved.

[0024] In combination with the above and the above drawings, the working principle of the lock 100 will be described in detail as follows:

[0025] When unlocking, first, the key is inserted into the lock cylinder 6, the lock cylinder 6 is twisted, and the engaging portion 61 of the lock cylinder 6 is rotated away from the engaging groove 32. Then, the pull handle 2 is manually pulled, the pull handle 2 is rotated upward relative to the seat body 1, the pull handle 2 is rotated around the pivot shaft 21, the driving portion 24 is rotated and pushes the swing arm 3, and the swing arm 3 is rotated around the center axis of the mounting column 1b. At this time, the pushing slope 31 of the swing arm 3 pushes the abutting portion 41, and then drives the lock tongue 4 to slide in the sliding groove 1c against the elastic force of the elastic reset member 5, and the front end of the lock tongue 4 is retracted into the seat body 1. At this time, the lock 100 can unlock the engine cover, and the engine cover can be popped up. When locking, only the pull handle 2 needs to be released, the lock tongue 4 is extended out of the seat body 1 under the elastic recovery force of the elastic reset member 5, then the engine cover is closed, and the lock tongue 4 can be reinserted into the side cover of the automobile to achieve locking.

[0026] Compared with the prior art, this utility model has a very simple structure. The handle 2 is pivotally connected to the base 1 and embedded within the receiving cavity 1a of the base 1. The swing arm 3 is also pivotally connected to the base 1. A pushing inclined surface 31 is provided on the swing arm 3, and a stop 41 that cooperates with the pushing inclined surface 31 is provided on the locking tongue 4. The handle 2 drives the swing arm 3 to rotate, thereby pushing the locking tongue 4 relative to the base 1 through the pushing inclined surface 31, causing it to retract into the base 1. The elastic reset member 5 can also automatically extend out of the base 1, achieving the purpose of locking or unlocking. Furthermore, to unlock, the handle 2 is pulled, and to lock, the handle 2 is simply released, making operation very convenient.

[0027] In addition, such as Figure 5 As shown, in another embodiment, the embedded pull-type vehicle hood security lock 100' of this utility model has the same structure as the above embodiment, except that the pull handle 2' in this embodiment has a pull portion 22' for hand gripping. An opening 23' is formed at an interval between the end of the pull portion 22' away from the pivot shaft 21' and the side wall of the opposite receiving cavity 1a'. Thus, the opening 23' can also be gripped by hand, achieving a similar technical effect to the above embodiment.

[0028] The lock cylinder 6 structure involved in this utility model's embedded pull-type vehicle hood security lock 100 is well known to those skilled in the art and will not be described in detail here.

[0029] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
