[0077] Please refer to Figure 1 、 Figure 5 、 Figure 6 and Figure 7 , the box assembly 1 comprises a box 11 and a fixed plate 12. The opening is arranged on one side of the box 11, and the opening and the inside of the box 11 form a containing cavity. The fixed plate 12 is fixed in the containing cavity and is distributed on the outside of the opening. The fixed plate 12 is provided with a connecting hole 121 for the damping assembly 4 to pass through.

[0078] In the embodiment, the opening is arranged on the front side of the box assembly 1. The fixing plates 12 are two and symmetrically arranged on the left and right sides of the opening. The fixing plates 12 are vertically arranged. The cover plate assembly 2 is arranged between the two fixing plates 12. The rotating end of the cover plate assembly 2 is the upper end, and the free end of the cover plate assembly 2 is the lower end. The front side of the cover plate assembly 2 is adapted to cover the opening, and the rear side of the cover plate assembly 2 is adapted to pass through the opening and extend into the accommodating cavity.

[0079] Further, referring to Figure 1 , it is shown that the side wall of the box 11 is provided with a heat dissipation hole 112 for heat dissipation of the accommodating cavity.

[0080] Further, referring to Figure 1 and Figure 2 , it is shown that the box assembly 1 further comprises a supporting leg 13 and a carrying handle 14. The supporting leg 13 is arranged at the bottom of the box 11 to support the box 11 so that the bottom of the box 11 can be heat dissipated. The carrying handle 14 is embedded in the top of the box 11 to facilitate the staff to carry the display device.

[0081] Referring to Figure 4 , Figure 5 and Figure 8 , it is shown that the cover plate assembly 2 comprises a cover plate 21, a fan-shaped side plate 22 and a limiting plate 23. The cover plate 21 is arranged on the front side of the opening and adapted to cover the opening. The display screen 3 is embedded in the cover plate 21. The fan-shaped side plate 22 is two and arranged on the left and right sides of the display screen 3. Specifically, the two fan-shaped side plates 22 are symmetrically arranged on the left and right sides of the cover plate 21 and located on the side of the cover plate 21 close to the accommodating cavity (i.e. the rear side of the cover plate 21). The fan-shaped side plate 22 is adapted to pass through the opening and extend into the accommodating cavity. The fan-shaped side plate 22 comprises an opposite corner end (i.e. the upper end) and an arc-shaped end (i.e. the lower end). The corner end is the rotating end and rotationally connected to the box assembly 1. The arc-shaped end is the free end and cooperates with the damping assembly 4.

[0082] In the embodiment, the cover plate 21 and the two fan-shaped side plates 22 are an integral structure. The two fan-shaped side plates 22 are formed by bending the plate material constituting the cover plate 21. This structure is simple in process and low in cost.

[0083] In the embodiment, the left and right sides of the cover plate assembly 2 are slidingly connected with the opening, i.e. the side wall of the fan-shaped side plate 22 is slidingly connected with the opening. Further, the lower end of the opening is provided with a slot slidingly connected with the arc-shaped end of the fan-shaped side plate 22. The slot is arranged on the front side wall of the box 11 and communicates with the opening.

[0084] In the embodiment, the corner end of the fan-shaped side plate 22 is provided with a pin shaft 25. The pin shaft 25 is rotationally connected to the fixing plate 12 so that the corner end of the fan-shaped side plate 22 is rotationally connected to the fixing plate 12.

[0085] Further, a limiting plate 23 is arranged on the fan-shaped side plate 22 and located in the accommodating cavity. The limiting plate 23 cooperates with the cover plate 21 to limit the rotation angle of the fan-shaped side plate 22, thereby limiting the overturning angle of the cover plate 21.

[0086] In this embodiment, the length of the cover plate 21 is equal to the length of the opening, and the width of the cover plate 21 is greater than the width of the opening. Please refer to Figure 1 When the lower end of the cover plate 21 is overturned to the lowest position (i.e. the cover plate 21 is vertically arranged), the opening can limit the cover plate 21 to prevent the cover plate 21 from continuing to overturn backward under the action of external force. Please refer to Figure 4 and Figure 5 When the lower end of the cover plate 21 is overturned to the highest position, the damping assembly 4 can limit the limiting plate 23 to prevent the cover plate 21 from continuing to overturn forward under the action of external force.

[0087] Further, please refer to Figure 3 In order to facilitate the overturning of the cover plate 21, the edge of the cover plate 21 away from the sharp corner end extends to the outside of the box body 11, that is, the lower edge of the cover plate 21 protrudes from the bottom surface of the box body 11.

[0088] Further, please refer to Figure 8 The cover plate assembly 2 further comprises a protective plate 24. The protective plate 24 is located on the side of the cover plate 21 close to the accommodating cavity (i.e. the back side of the cover plate 21). The protective plate 24 is connected with the cover plate 21 and the fan-shaped side plate 22 respectively. In this embodiment, the front edge of the protective plate 24 is connected with the back side of the cover plate 21. The left and right edges of the protective plate 24 are connected with the middle lower parts of the corresponding fan-shaped side plates 22 respectively. The cover plate 21, the fan-shaped side plates 22 and the protective plate 24 enclose a protection cavity. The display screen 3 is placed in the protection cavity, and the damping assembly 4 is placed outside the protection cavity.

[0089] Further, the bottom surface of the protective plate 24 is in sliding connection with the opening to effectively seal the inner cavity of the box body 11, so as to prevent paper scraps and sundries from entering the inner cavity of the box body 11 from the opening after the cover plate assembly 2 is overturned.

[0090] In this embodiment, the damping assembly 4 is two and symmetrically distributed on the left and right sides of the opening, for clamping the arc-shaped end edge of the corresponding fan-shaped side plate 22.

[0091] Please refer to Figure 7 and Figure 9 The damping assembly 4 comprises a connecting rod 41, a fixed sleeve 42, an elastic piece 43 and two wear-resistant sheets 44. The connecting rod 41 is placed in the inner cavity of the box body 11 and is installed on the fixed plate 12. The axis of the connecting rod 41 is parallel to the rotation axis of the cover plate assembly 2, that is, the connecting rod 41 extends in the horizontal direction.

[0092] Specifically, in the same damping assembly 4, the connecting rod 41 comprises a large-diameter section 411 and a small-diameter section 412. The large-diameter section 411 is distributed on the side of the corresponding fixed plate 12 close to the opening. The fixed sleeve 42 is distributed on the side of the corresponding fixed plate 12 away from the opening. The starting end of the small-diameter section 412 is fixed on the large-diameter section 411. The terminal end of the small-diameter section 412 is threaded through the connecting hole 121 and is screwed with the fixed sleeve 42. The small-diameter section 412 is sequentially sleeved with the elastic piece 43 and the two wear-resistant sheets 44. The elastic piece 43 and the two wear-resistant sheets 44 are both distributed on the side of the corresponding fixed plate 12 close to the opening, i.e., between the fixed plate 12 and the large-diameter section 411. The two wear-resistant sheets 44 are distributed on the left and right sides of the arc-shaped end of the corresponding sector-shaped side plate 22. One end of the elastic piece 43 is fixed on the end face of the large-diameter section 411; the other end of the elastic piece 43 is adapted to abut against the adjacent wear-resistant sheet 44, so that the two wear-resistant sheets 44 clamp the left and right sides of the arc-shaped end of the corresponding sector-shaped side plate 22, and the fixed sleeve 42 abuts against the adjacent wear-resistant sheet 44 through the corresponding fixed plate 12.

[0093] In the embodiment, the material of the wear-resistant sheet 44 is PVC, which is wear-resistant.

[0094] In the embodiment, the elastic piece 43 is a spring.

[0095] Further, the damping assembly 4 further comprises two fixed sheets 45 and a support sheet 46. In the same damping assembly 4, one fixed sheet 45 is arranged between the fixed plate 12 and the fixed sleeve 42, and the fixed sheet 45 is sleeved on the corresponding small-diameter section 412. Another fixed sheet 45 is arranged between the wear-resistant sheet 44 close to the fixed sleeve 42 and the fixed plate 12, and the fixed sheet 45 is sleeved on the small-diameter section 412. The support sheet 46 is arranged between the wear-resistant sheet 44 away from the fixed sleeve 42 and the elastic piece 43, and the support sheet 46 is sleeved on the small-diameter section 412.

[0096] In the embodiment, the materials of the fixed sheet 45 and the support sheet 46 are both steel materials, which have high strength and are used to effectively support the wear-resistant sheet 44 to prevent the wear-resistant sheet 44 from being deformed.

[0097] Further, in order to adjust the damping force of the damping assembly 4, please refer to Figure 10 It is shown that the small-diameter section 412 is provided with an anti-rotation face 413. Specifically, the anti-rotation face 413 is in close contact with the matching face in the connecting hole 121 to prevent the small-diameter section 412 from rotating circumferentially. Please refer to Figure 5 It is shown that the fixed sleeve 42 is arranged close to the side wall of the box body 11. The side wall of the box body 11 is provided with an operation hole 111. The fixed sleeve 42 is exposed to the operation hole 111, so that the fixed sleeve 42 can be rotated to adjust the deformation amount of the elastic piece 43. Specifically, the position of the operation hole 111 is arranged opposite to the fixed sleeve 42, so that the worker can pass the auxiliary tool through the operation hole 111 and connect the auxiliary tool with the fixed sleeve 42, and then rotate the fixed sleeve 42.

[0098] Further, the end of the fixed sleeve 42 away from the small diameter section 412 is provided with an external hexagonal structure or an internal hexagonal hole. In this embodiment, the end of the fixed sleeve 42 away from the small diameter section 412 is provided with an internal hexagonal hole, and the auxiliary tool is a hexagonal wrench. Specifically, the center of the fixed sleeve 42 is provided with a threaded hole and an internal hexagonal hole along the axial direction. The threaded hole is threadedly connected with the small diameter section 412. The internal hexagonal hole is exposed to the operation hole 111, so that the staff can rotate the fixed sleeve 42 by using the auxiliary tool.

[0099] Further, in order to effectively protect the elastic member 43, the damping assembly 4 further comprises a protective sleeve 47. In the same damping assembly 4, the protective sleeve 47 is arranged between the wear-resistant sheet 44 away from the fixed sleeve 42 and the elastic member 43. In this embodiment, the protective sleeve 47 is arranged between the support sheet 46 and the elastic member 43. The protective sleeve 47 is sleeved on the small diameter section 412 and covers the outside of the elastic member 43. The elastic member 43 is adapted to abut on the adjacent wear-resistant sheet 44 through the protective sleeve 47 and the support sheet 46, so that the two wear-resistant sheets 44 clamp the left and right sides of the corresponding arc-shaped end of the fan-shaped side plate 22, and the fixed sleeve 42 abuts on the adjacent wear-resistant sheet 44 through the fixed sheet 45 and the fixed plate 12.

[0100] The protective sleeve 47 is adapted to prevent the elastic member 43 from being excessively compressed. When the elastic member 43 is compressed to a certain extent, the end face of the protective sleeve 47 is in contact with the end face of the large diameter section 411, so as to prevent the elastic member 43 from being continuously compressed.

[0101] The principle of the display device is as follows:

[0102] When the display device is idle, the cover plate assembly 2 is retracted, i.e., the cover plate 21 is vertically arranged. At this time, the display device effectively saves space, is convenient to carry, and has strong practicability.

[0103] When the display device is working, the cover plate assembly 2 is flipped as needed, so that the cover plate 21 is arranged in an inclined manner; after the cover plate 21 is flipped to the required angle, the flipping is stopped. At this time, one end of the elastic member 43 is fixed on the end face of the large diameter section 411, and the other end of the elastic member 43 is adapted to indirectly abut on the adjacent wear-resistant sheet 44 through the protective sleeve 47 and the support sheet 46, so that the two wear-resistant sheets 44 clamp the left and right sides of the corresponding arc-shaped end of the fan-shaped side plate 22, and the fixed sleeve 42 abuts on the adjacent wear-resistant sheet 44 through the corresponding fixed plate 12 and the fixed sheet 45.

[0104] When it is found that the damping assembly 4 cannot effectively keep the cover plate assembly 2 at a certain position, the staff can replace a new damping assembly 4 or rotate the fixed sleeve 42 through the operation hole 111 to adjust the damping force of the damping assembly 4, so that the two wear-resistant sheets 44 can effectively clamp the left and right sides of the corresponding arc-shaped end of the fan-shaped side plate 22, i.e., the damping assembly 4 can effectively keep the cover plate assembly 2 at a certain position.

[0105] In another aspect, a hydraulic monitoring gun is provided. The hydraulic monitoring gun comprises a hydraulic station, a hydraulic rivet tool, a communication cable, a controller and the display device as described above. The hydraulic rivet tool is connected with the controller and the hydraulic station through the communication cable. The controller is arranged in the accommodating cavity and connected with the display screen 3. In this embodiment, the hydraulic rivet tool is a rivet gun.

[0106] In this embodiment, the hydraulic station, the hydraulic rivet tool, the communication cable and the controller are all prior arts, and thus are not described in detail.

[0107] In this embodiment, the box body 11 is further provided with a plug for connecting with the cable.

[0108] When the staff uses the hydraulic rivet tool to work, the display screen 3 can be set at different inclination angles as needed to provide better display effect and improve the comfort of the staff.
