[0033] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0034] An anti-prying protection structure for a box body, as shown in the attached Figure 1 to the attached Figure 7 figures, the anti-prying protection structure for the box body includes: a strut bracket 2 and a strut 3.
[0035] Specifically, as shown in the attached Figure 1 to the attached Figure 7 figures, the strut bracket 2 is connected to the door 11 of the box body 1. Specifically, the door 11 includes a first door surface exposed outside the box body 1 and a second door surface hidden inside the box body 1, and the strut bracket 2 is connected to the second door surface of the door 11. Among them, the strut bracket 2 can be welded to the second door surface, or the strut bracket 2 can be detachably connected to the door 11, that is, a connection structure is provided on the second door surface of the door 11, and the strut bracket 2 is connected to the connection structure provided on the second door surface of the door 11 through a connecting piece. A through hole a is provided on the strut bracket 2, and the first axial end of the strut 3 is connected to the box lock of the box body 1 and the strut 3 can pass through the through hole a. When the box lock of the box body 1 is closed, the strut 3 will move, and when the box lock is completely closed, the second axial end of the strut 3 abuts against the side plate of the box body 1; when the box lock is opened, the strut 3 will contract, and when the box lock is completely opened, the second axial end of the strut 3 will retract to the area of the door 11. When a thief pries the door 11 from the outside, due to the setting of the strut 3, the force of prying from the outside of the door 11 can be blocked. Due to the setting of the strut bracket 2, the strut bracket 2 can stabilize the strut 3 during the process of prying the door 11 by an external force, so as to enhance the ability of the strut 3 to resist the external prying force.
[0036] In this embodiment, by setting the strut bracket 2 and the strut 3, the strut 3 passes through the through hole a and is lapped on the strut bracket 2, and the strut 3 is connected to the box lock so that the strut 3 can move when the box lock is closed. When the strut 3 moves to abut against the side plate of the box body 1, the effect of preventing the door from being pried is achieved.
[0037] Further, the through hole a is an L-shaped through hole, the cross section of the strut 3 is L-shaped, and the strut 3 passes through the L-shaped through hole and is lapped on the strut bracket 2. Specifically, as shown in the attached Figure 7As shown in the figure, the support rod 3 is set as a rod with an L-shaped cross-section, and an L-shaped through-hole with the same cross-section as the support rod 3 is opened on the support rod bracket 2. Therefore, the support rod 3 can pass through the L-shaped through-hole of the support rod bracket 2 and overlap on the support rod bracket 2. By setting the support rod 3 as a rod with an L-shaped cross-section, that is, the support rod 3 has two sides, and when the support rod 3 passes through the L-shaped through-hole of the support rod bracket 2, the two sides of the support rod 3 are in contact with the L-shaped through-hole. When prying the box door 11 from the outside, according to the characteristics of the L-shaped rod, that is, the support rod 3 has supporting forces in two side directions. In this embodiment, the cooperation between the support rod 3 and the support rod bracket 2 resists the external prying force. Since the support rod 3 has supporting forces in two side directions, the resistance effect against the external prying force is further enhanced.
[0038] Further, the support rod bracket 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is connected to the second bracket 22. The second bracket 22 is provided with a through-hole 221, and the second bracket 22 is connected to the box body 1 through a connecting piece passing through the through-hole 221. Specifically, as shown in the attached Figure 1 and attached Figure 2 and attached Figure 4 As shown in the figure, the support rod bracket 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is connected to the second bracket 22. A through-hole a for the support rod 3 to pass through is opened on the first bracket 21, which facilitates the support rod 3 to pass through the through-hole a and overlap on the support rod bracket 2. The second bracket 22 is provided with a through-hole 221 for the connecting piece to pass through, so that the connecting piece can pass through the through-hole 221 and be connected to the box door 11 of the box body 1. When a thief pries the box door 11 from the outside, due to the setting of the support rod 3, the force of prying the box door 11 from the outside can be blocked. Due to the setting of the support rod bracket 2, the support rod 3 is stabilized by the support rod bracket 2 during the process of prying the box door 11 by an external force.
[0039] Further, the second bracket 22 includes a first box body connecting portion that is vertically connected to the first bracket 21 and extends upward, and a second box body connecting portion that is vertically connected to the first bracket 21 and extends downward. Both the first box body connecting portion and the second box body connecting portion are provided with through-holes 221, and both the first box body connecting portion and the second box body connecting portion are connected to the box door 11 through connecting pieces passing through the through-holes 221. Specifically, as shown in the attached Figure 1 and attached Figure 2 and attached Figure 4As shown in the figure, in order to make the force on the strut bracket 2 more balanced, the second bracket 22 of the strut bracket 2 includes a first box connecting portion and a second box connecting portion. Among them, the first box connecting portion is vertically connected to the first bracket 21 and extends upward, and the second box connecting portion is vertically connected to the first bracket 21 and extends downward. From the front view, the first box connecting portion and the second box connecting portion are centrosymmetric. At the same time, through holes 221 are provided in both the first box connecting portion and the second box connecting portion. The same connecting pieces are respectively passed through the through holes 221 of the first box connecting portion and the second box connecting portion and then connected to the door 11, thereby realizing the connection between the strut bracket 2 and the door 11. By providing the first box connecting portion and the second box connecting portion, and connecting the strut bracket 2 to the door 11 through the connecting pieces passing through the through holes 221 of the first box connecting portion and the second box connecting portion, the force on the strut bracket 2 can be made more balanced.
