DETAILED DESCRIPTION

[0036] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0037] In the embodiment of the present application, an instrument protection box 100 is provided for protecting an instrument. For the specific structure of the instrument protection box 100, please refer to Figures 1 to 4 , which includes a box body 110, a cover body 120 and a limiting mechanism 130, wherein the limiting mechanism 130 is respectively connected to the box body 110 and the cover body 120, and is used to adjust the opening angle of the cover body 120 relative to the box body 110, wherein an opening is provided on one side of the box body 110, and the instrument is placed in the box body 110 through the opening of the box body 110; the cover body 120 is flippably provided at the opening, and the cover body 120 can be flipped upward from a closed position to an open position, so that maintenance personnel can regularly perform maintenance on the instrument; the limiting mechanism 130 includes a guide rail 135, a first connecting rod 131 and a second connecting rod 132, and the guide rail 135 is provided at On the box body 110, the guide rail 135 is provided with a slide groove 1351 extending along its longitudinal direction, and a slider assembly 136 capable of sliding therein is provided in the slide groove 1351; the two ends of the first connecting rod 131 are pivotally connected to the cover body 120 and the guide rail 135 respectively, and the connecting end of the first connecting rod 131 and the guide rail 135 is located below the slider assembly 136; one end of the second connecting rod 132 is pivotally connected to the slider assembly 136, and the other end is pivotally connected to the middle part of the first connecting rod 131, and the guide rail 135, the first connecting rod 131 and the second connecting rod 132 can form a deformable triangular structure to support the cover body 120.

[0038] According to the applied instrument protection box 100, the limit mechanism 130 can adjust the opening angle of the cover body 120 relative to the box body 110. In the process of the cover body 120 flipping upward to open, the guide rail 135, the first connecting rod 131 and the second connecting rod 132 can form a deformable triangular structure to support the cover body 120, which is beneficial for maintenance personnel to freely control the opening and closing degree of the cover body 120 according to actual needs, so that the opening angle of the cover body 120 relative to the box body 110 is more flexible and controllable. At the same time, it ensures that the cover body 120 is stably maintained in the open position, so that the maintenance of the instruments inside the box body 110 is more convenient and safer.

[0039] like Figure 1As shown, the two ends of the first connecting rod 131 are pivotally connected to the cover body 120 and the guide rail 135 respectively, and the two ends of the second connecting rod 132 are pivotally connected to the slider assembly 136 and the middle part of the first connecting rod 131, so that the cover body 120 can be more smoothly flipped upward to open the opening of the box body 110 or flipped downward to cover the opening of the box body 110, and the operation is time-saving and labor-saving.

[0040] Preferably, two limit mechanisms 130 are symmetrically arranged on the left and right sides of the opening of the box body 110, and are respectively connected to the box body 110 and the cover body 120. The cover body 120 can be flipped up or down more smoothly to prevent the cover body 120 from shaking during the flipping opening or closing process, thereby improving the user experience.

[0041] like Figure 3 and Figure 4 As shown, the slide groove 1351 is a C-shaped groove with an open top, and the slider assembly 136 is inserted into the C-shaped groove through the open plug-in, which is conducive to the assembly and disassembly of the slider assembly 136, realizes the maintenance and replacement of the slider assembly 136, and extends the service life of the limiting mechanism 130.

[0042] like Figure 3 and Figure 4 As shown, the instrument protection box 100 also includes a stop member 137, which is located above the slider assembly 136 and is inserted into the C-shaped groove through an open plug-in to prevent the slider assembly 136 from disengaging from the slide groove 1351 during the longitudinal sliding process along the guide rail 135. It has good limiting and guiding effects, ensuring that the slider assembly 136 can slide smoothly in the slide groove 1351.

[0043] For the specific structure of the stop member 137, please refer to Figure 3 and Figure 4 , which includes a stop portion 1371 and an inserting portion 1372, wherein the stop portion 1371 and the inserting portion 1372 are integrally connected and vertically arranged to each other, the stop portion 1371 extends in the horizontal direction, and the extending end of the stop portion 1371 is bent downward and extended to form the inserting portion 1372, and the inserting portion 1372 is inserted downward into the slide groove 1351 through the opening of the slide groove 1351, and the stop portion 1371 is in contact with the top limit of the slide groove 1351, thereby blocking the opening at the top of the slide groove 1351, preventing the slider assembly 136 from detaching from the slide groove 1351 during the longitudinal sliding process along the guide rail 135, thereby ensuring safety in use.

[0044] Preferably, slideways are formed on the left and right sides of the plug-in portion 1372, and corresponding clamping protrusions are formed on the corresponding positions of the stop portion 1371. When the plug-in portion 1372 is inserted downward into the slide groove 1351 through the open end of the slide groove 1351, the opening edge 1352 of the slide groove 1351 can fit on the slideway and be clamped and fixed by the clamping protrusion above. Under the abutment restriction of the slideway, the stop member 137 is ensured not to swing left and right in the slide groove 1351, thereby ensuring that the limiting mechanism 130 has better stability.

[0045] like Figure 2 As shown, a boss 138 is formed in the slide groove 1351 and extends toward its open end. One end of the first connecting rod 131 is pivotally connected to the guide rail 135 through the boss 138, so that the first connecting rod 131 can rotate relative to the guide rail 135, and the thickness of the boss 138 and the slider assembly 136 are greater than the depth of the slide groove 1351, that is, the first connecting rod 131 and the second connecting rod 132 both protrude from the opening edge 1352 of the slide groove 1351, which can avoid friction between the first connecting rod 131 and the second connecting rod 132 and the slide groove 1351, which is beneficial to extending the service life of the limiting mechanism 130 and improving safety.

[0046] like Figure 3 and Figure 4 As shown, a limit block 139 for limiting the sliding position of the slider assembly 136 is formed in the slide groove 1351, and the limit block 139 is located below the slider assembly 136. When the slider assembly 136 slides downward and abuts against the limit block 139, the slider assembly 136 stops sliding downward, which can control the maximum opening angle of the cover body 120 relative to the box body 110, and the limit block 139 can improve the stability of the triangular structure formed by the guide rail 135, the first connecting rod 131 and the second connecting rod 132 by supporting the slider assembly 136.

[0047] Preferably, the slider assembly 136 includes a slider body and an inlaid component, wherein the slider body can be slidably arranged in the slide groove 1351; the inlaid component is cast on the outer side of the slider body, and the slider body and the inlaid component are cast into an integral part. This design not only improves the wear resistance of the slider assembly 136, but also enhances the overall structural strength of the slider assembly 136. Even after long-term use, it is not easy to deform or break, and the cover body 120 can be prevented from falling, thereby improving safety.

[0048] As an embodiment not shown, the instrument protection box 100 also includes a handle, which is located at the bottom end of the cover body 120 or one side of the cover body 120 and is connected to the cover body 120. The maintenance personnel can flip the handle upward to open the opening of the box body 110, which is simple and labor-saving to operate.

[0049] As an embodiment not shown, the cover body 120 is provided with a hand latch groove which is recessed toward the interior of the box body 110. The hand latch groove is located at the bottom end of the cover body 120 or one side of the cover body 120. Maintenance personnel can flip the opening of the box body 110 upwards through the hand latch groove. The structure is simple, the number of parts used is small, and the production cost is low.

[0050] Preferably, the instrument protection box 100 also includes a sealing ring, which is sleeved on the opening edge of the box body 110, wherein the outer contour of the sealing ring is adapted to the opening shape of the box body 110, and when the cover body 120 is flipped downward to cover the opening of the box body 110, the sealing ring fits tightly against the cover body 120, so that the insulation has better heat insulation, dustproof and waterproof properties.

[0051] As an embodiment not shown, the top of the cover 120 is pivotally connected to the top of the box 110 , and the cover 120 can be more smoothly flipped upward to open the opening of the box 110 or flipped downward to cover the opening of the box 110 .

[0052] As an embodiment not shown, the cover body 120 is arranged in the opening of the box body 110 and is sleeved with the box body 110. The outer contour of the cover body 120 is adapted to the opening shape of the box body 110. The cover body 120 is connected to the box body 110 through a limiting mechanism 130 and is flippably connected to the box body 110 through the limiting mechanism 130. The connection structure is simple, the number of parts used is small, and the production cost is low.

[0053] like Figure 4 As shown, as an optional embodiment, the limiting mechanism 130 further includes a third link 133 and a fourth link 134, wherein the third link 133 is arranged above the second link 132, and one end of the third link 133 is pivotally connected to the slider assembly 136; the fourth link 134 is arranged on the cover body 120, the top end of the fourth link 134 is pivotally connected to the other end of the third link 133, and one end of the first link 131 is pivotally connected to the middle of the fourth link 134, so that one end of the first link 131 is pivotally connected to the cover body 120 through the fourth link 134. 20 is pivotally connected. By setting a third connecting rod 133 and a fourth connecting rod 134, it is possible to promote the decomposition and transmission of force, so that the force on the entire limiting mechanism 130 is more dispersed, thereby reducing the pressure between the pivotal connecting parts and improving the deformation and damage resistance of the pivotal connecting parts to a certain extent. In particular, the box body 110 and the cover body 120 are flippably connected through the limiting mechanism 130. The third connecting rod 133 can better disperse the force, ensure that the cover body 120 is firmly connected to the box body 110, and avoid shaking of the cover body 120 during the flipping process.

[0054] like Figure 4As shown, the length of the second connecting rod 132 is greater than the length of the third connecting rod 133, and less than the length of the fourth connecting rod 134. This can not only increase the opening angle of the cover body 120 relative to the box body 110 and improve the operating space for maintenance personnel, but also enable the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 to overlap when the cover body 120 is in a closed state, thereby reducing the space occupied by the limiting mechanism 130 and improving the utilization rate of the internal space of the instrument protection box 100.

[0055] like Figure 4 As shown, a stop surface 1373 is formed on one side of the stop portion 1371 close to the slide groove 1351, and the stop surface 1373 and the top end surface of the third connecting rod 133 can fit together. When the cover body 120 is in a closed state, the stop surface 1373 and the top end surface of the third connecting rod 133 fit together, and the fourth connecting rod 134 can be in the same vertical line with the slide groove 1351, so that the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 are in a straight line as a whole. At this time, the cover body 120 cannot be flipped upward to open, thereby reducing the risk of damage to the instrument protection box 100.
