Description

Technical Field

[0001] This utility model belongs to the field of bulletproof plate technology, and in particular relates to a lightweight, high-strength composite bulletproof plate. Background Technology

[0002] A bulletproof plate is a special protective device used to absorb and disperse the impact energy of a bullet. It is mainly used to improve the protection of individuals or equipment and prevent ballistic threats. Bulletproof plates are usually made of high-strength materials, such as ceramics and polymers. Lightweight high-strength composite bulletproof plates are also a type of bulletproof plate.

[0003] Most existing bulletproof plates are fixed-design plates that cannot be automatically and quickly increased in thickness according to actual needs. This makes it impossible to improve the overall ballistic performance of the bulletproof plate in a timely and rapid manner, which directly reduces the overall effectiveness of the bulletproof plate and makes it impossible to quickly provide users with high safety protection in special environments. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a lightweight, high-strength composite bulletproof plate, which solves the problem that most existing bulletproof plates are fixed-design plates that cannot be automatically and quickly increased in thickness according to actual needs, resulting in the inability to improve the overall bulletproof performance of the bulletproof plate in a timely and rapid manner.

[0005] This utility model is implemented as follows: a lightweight, high-strength composite bulletproof plate includes two sets of bulletproof plate bodies symmetrically placed in the front-back direction, and further includes: grooves formed around the back of each set of bulletproof plate bodies, the two sets of bulletproof plate bodies are attached to each other on their adjacent sides, a fixing shaft is fixed in each set of grooves, a side plate is rotatably mounted on the fixing shaft, and a locking component that cooperates with the side plate is provided on the side of the bulletproof plate body.

[0006] As a preferred embodiment of this utility model, the locking assembly includes square holes formed on the side plate, locking pins inserted into two adjacent sets of square holes, two sets of through holes symmetrically formed on each set of locking pins along the front-back direction, a positioning seat slidably arranged in each set of through holes, a positioning groove for the positioning seat to be inserted on the bulletproof plate body, a spring fixed to the end of the positioning seat away from the positioning groove, and one end of the spring fixed to the outside of the inner cavity of the through hole.

[0007] As a preferred embodiment of this invention, one side of the locking post is attached to the bulletproof plate body.

[0008] As a preferred embodiment of this invention, an auxiliary elastic pad that works in conjunction with the side plate is fixed inside the groove.

[0009] As a preferred embodiment of this invention, the overall length of the fixed shaft is the same as the longitudinal width of the groove.

[0010] As a preferred embodiment of this invention, both the locking pin and the positioning seat are T-shaped structures.

[0011] As a preferred embodiment of this invention, a gap is reserved between the side plate and the inner side of the groove cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting a locking component and using the insertion of the locking pin and the square hole, can pre-position two sets of bulletproof plate bodies. The elastic rebound of the spring causes the positioning seat to engage with the corresponding positioning groove, thus quickly fixing the locking pin and effectively preventing it from detaching from the square hole. Furthermore, the two sets of bulletproof plate bodies can be quickly fixed using a snap-fit ​​method, effectively increasing the overall thickness of the bulletproof plate bodies. This allows for a timely and rapid improvement in the overall bulletproof performance of the bulletproof plate bodies, providing users with enhanced safety protection in special environments.

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5As shown in the figure, the present invention provides a lightweight high-strength composite bulletproof plate, including two sets of bulletproof plate bodies 1 symmetrically placed in the front-back direction, and further including: grooves 2 formed around the back of each set of bulletproof plate bodies 1, the two sets of bulletproof plate bodies 1 are attached to each other on the side closest to each other, a fixing shaft 11 is fixed in each set of grooves 2, a side plate 3 is rotatably mounted on the fixing shaft 11, and a locking component is provided on the side of the bulletproof plate body 1 to cooperate with the side plate 3. By setting the locking component and using a snap-fit ​​method, the two sets of bulletproof plate bodies 1 can be quickly combined and fixed, which can effectively increase the overall thickness of the bulletproof plate body 1, thereby improving the overall bulletproof performance of the bulletproof plate body 1 in a timely and rapid manner, so as to quickly provide users with higher safety protection in special environments.

[0024] As a preferred embodiment of this utility model, the locking assembly includes square holes 4 formed on the side plate 3, locking pins 5 inserted into two adjacent sets of square holes 4, two sets of through holes 7 symmetrically formed along the front-back direction on each set of locking pins 5, and a positioning seat 8 slidably arranged in each set of through holes 7. A positioning groove 10 for the positioning seat 8 to be inserted is formed on the bulletproof plate body 1. A spring 9 is fixed to one end of the positioning seat 8 away from the positioning groove 10, and one end of the spring 9 is fixed to the outside of the inner cavity of the through hole 7. The design of the locking pins 5 and square holes 4 can pre-position the two sets of bulletproof plate bodies 1, and with the spring 9, positioning seat 8 and corresponding positioning groove 10, the locking pins 5 can be quickly fixed, thereby quickly fixing the two sets of bulletproof plate bodies 1 to increase the overall bulletproof performance of the bulletproof plate body 1.

[0025] As a preferred embodiment of this invention, one side of the locking post 5 is attached to the bulletproof plate body 1 to avoid gaps between the locking post 5 and the bulletproof plate body 1, which would affect assembly stability.

[0026] As a preferred embodiment of this utility model, an auxiliary elastic pad 6 is fixed in the groove 2 to cooperate with the side plate 3. The design of the auxiliary elastic pad 6 utilizes its elasticity to squeeze and position the side plate 3 when it is reset, thus preventing the side plate 3 from swinging randomly when it is not in use.

[0027] As a preferred embodiment of this invention, the overall length of the fixed shaft 11 is the same as the longitudinal width of the groove 2, so that the two sets of bulletproof plate bodies 1 can fit together tightly.

[0028] As a preferred embodiment of this utility model, both the locking pin 5 and the positioning seat 8 are T-shaped structures. The shape limitation of the locking pin 5 facilitates the user to quickly insert the locking pin 5, and the shape limitation of the positioning seat 8 can limit the positioning seat 8 and prevent it from easily dislodging from the through hole 7, while also providing sufficient assembly area for the spring 9.

[0029] As a preferred embodiment of this utility model, a gap is reserved between the side plate 3 and the inner side of the groove 2. The gap is designed so that the side plate 3 can rotate freely within the groove 2.

[0030] The working principle of this utility model:

[0031] refer to Figures 1 to 5 The user pulls the side plate 3 outwards and swings it, bringing the two sets of bulletproof plate bodies 1 together until they swing from a vertical to a horizontal position. At this point, the user pulls one set of positioning seats 8 outwards, causing it to move inwards and compress the spring 9. Simultaneously, the user inserts one end of the locking pin 5 into the front set of square holes 4 until the pulled positioning seat 8 enters the front set of square holes 4. The user then releases the positioning seat 8 and continues to pull the other set of positioning seats 8. As the locking pin 5 continues to move, one set of positioning seats 8 will directly insert into the spring under the elastic force of the spring 9. The locking pin 5 is positioned in the rear positioning groove 10, and another set of positioning seats 8 is directly inserted into the front positioning groove 10. At this time, one side of the locking pin 5 is directly attached to the bulletproof plate body 1. The engagement between the positioning seat 8 and the corresponding positioning groove 10 can quickly fix the locking pin 5. With the square hole 4 restricting the locking pin 5, the two sets of bulletproof plate bodies 1 can be quickly fixed, which can effectively increase the overall thickness of the bulletproof plate body 1. This can improve the overall bulletproof performance of the bulletproof plate body 1 in a timely and rapid manner, so as to quickly provide users with higher safety protection in special environments.
