Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Example 1

[0029] like Figures 1 to 3As shown, a protective support device for a surveying data display tablet includes a support base plate 2; positioning side plates 1 are fixedly connected to both sides of the top surface of the support base plate 2; a display device 3 is rotatably mounted at one end between the two positioning side plates 1; a protective top plate 5 is rotatably mounted at the other end between the two positioning side plates 1; the display device 3 is located between the support base plate 2 and the protective top plate 5; a connecting shaft 4 is rotatably mounted between the display device 3 and the two positioning side plates 1; a positioning shaft 6 is rotatably mounted between the protective top plate 5 and the two positioning side plates 1.

[0030] In this utility model, the display device 3 is a tablet computer and is used to display surveying data;

[0031] In use, rotate the protective top plate 5 so that the protective top plate 3 rotates around the positioning shaft 6, exposing the display device 3. Then rotate the display device 3 so that the display device 3 rotates around the connecting shaft 4. Then rotate the protective top plate 3 in the opposite direction so that the protective top plate 3 can contact the back of the display device 3 for support, tilting the display device 3 for support. Place the support base plate 2 on the platform to display the survey data on the display device 3.

[0032] If there is no platform for placement and the user needs to hold the display, simply rotate the protective top plate 5 so that the protective top plate 3 rotates around the positioning pivot 6 to its maximum state, that is, the protective top plate 3 rotates to the bottom surface of the supporting base plate 2; the user can then hold the supporting base plate 2 to display the survey data on the display device 3.

[0033] After use and when carrying, rotate the display device 3 to retract it into the positioning side plates 1 on both sides. Then rotate the protective top plate 5 to cover the top surface of the display device 3. The support base plate 2 and the protective top plate 5 clamp and protect the upper and lower surfaces of the display device 3, reducing the space occupied by the device and making it convenient for staff to carry.

[0034] Example 2

[0035] like Figures 1 to 3 As shown, this second embodiment is an improvement on the first embodiment; a receiving groove 15 is provided on the side of the protective top plate 5 away from the positioning pivot 6; an extension plate 7 is slidably installed inside the receiving groove 15; a positioning strip 8 is fixedly installed on the side wall of the extension plate 7 away from the protective top plate 5; positioning slots 10 are provided on the side of the two positioning side plates 1 near the connecting pivot 4; the positioning strip 8 corresponds to the positioning slot 10;

[0036] When not in use or being carried, the extension plate 7 is pulled out from the inside of the receiving slot 15 to increase the coverage of the protective top plate 5. With the cooperation of the protective top plate 5 and the extension plate 7, the display device 3 can be completely covered. Then, the positioning strip 8 is inserted into the inside of the positioning slot 10 to limit the extension range of the extension plate 7 and fix the extension plate 7 and the protective top plate 5, thereby improving the protection effect on the display device 3.

[0037] Example 3

[0038] like Figures 1 to 3 As shown, this embodiment three is a further improvement on embodiment two; multiple positioning holes 12 are equidistantly provided on the side wall of the extension plate 7; a positioning pin 13 slides through the side wall of the protective top plate 5; the position of the positioning pin 13 is aligned with the position of the positioning hole 12; multiple retraction springs 9 are provided inside the receiving groove 15; the two ends of the retraction springs 9 are fixedly connected to the corresponding side walls inside the extension plate 7 and the receiving groove 15 respectively; multiple positioning plates 14 are fixedly installed equidistantly on the side wall of the display device 3; the arch height of the buffer plate 11 is greater than the thickness of the positioning plate 14;

[0039] When not in use or being carried, the positioning strip 8 is locked inside the slot 10, and the extension plate 7 is in a state of sliding out from inside the receiving slot 15. At this time, the retraction spring 9 is in a stretched state. Using the elastic force of the retraction spring 9, the extension plate 7 is pulled, so that the positioning strip 8 is firmly locked inside the slot 10, thereby ensuring the stability of the protection of the display device 3.

[0040] In use, pull the extension plate 7 so that it slides out from the inside of the receiving groove 15, causing the positioning strip 8 to move out from the inside of the slot 10. Then rotate the extension plate 7 and the protective top plate 5 to expose the display device 3. Then rotate the removed display device 3 to align the positioning hole 12 on the extension plate 7 with the positioning hole 12 on the protective top plate 5, and use the positioning pin 13 to fix it through, controlling and adjusting the distance the extension plate 7 extends from the inside of the receiving groove 15. Support and engage the extension plate 7 with the positioning plate 14 on the back of the display device 3 to tilt and support the display device 3. Control the length of the extension plate 7 and the protective top plate 5 through different positioning holes 12, and then control and adjust the tilt angle of the display device for data display by selecting different positioning plates 14, thereby facilitating the data display work.

[0041] Example 4

[0042] like Figures 1 to 4As shown, this fourth embodiment is a further improvement on the first embodiment; buffer plates 11 are provided on both sides of the top surface of the supporting base plate 2; one end of the buffer plate 11 is fixedly connected to the supporting base plate 2, and the other end of the buffer plate 11 is in sliding contact with the supporting base plate 2; the buffer plate 11 is arc-shaped.

[0043] When not in use or being carried, the support base plate 2 and the protective top plate 5 clamp and protect the upper and lower sides of the display device 3. At this time, the protective top plate 5 exerts downward pressure on the display device 3, causing the display device 3 to exert downward pressure on the buffer spring plate 11, causing the unfixed end of the buffer spring plate 11 to slide against the support base plate 2.

[0044] The elasticity of the buffer plate 11, in conjunction with the protective top plate 5, firmly fixes the display device 3, preventing the display device 3 from slipping due to gaps between it and the supporting base plate 2 and the protective top plate 5 after long-term use, thus improving the safety of the display device 3.

[0045] Meanwhile, due to the elasticity of the buffer plate 11, when the protective top plate 5 is rotated and the display device 3 is exposed, the buffer plate 11 is reset, which pushes the display device 3 up, making it easier to rotate and move the display device 3 out, thus improving the convenience of use.

[0046] Working principle: When not in use or being carried, rotate the display device 3 to retract it into the positioning side plates 1 on both sides, so that the back of the display device 3 contacts the middle protrusion of the buffer spring 11; pull the extension plate 7 out from the inside of the receiving groove 15 to increase the coverage of the protective top plate 5. With the cooperation of the protective top plate 5 and the extension plate 7, the display device 3 can be completely covered. Then, insert the positioning strip 8 into the inside of the positioning slot 10. At the same time, the tension spring 9 stretches and generates elastic force to pull the extension plate 7, so that the positioning strip 8 is firmly locked in the slot 10; at the same time, the protective top plate 5 exerts downward pressure on the display device 3, so that the display device 3 exerts downward pressure on the buffer spring plate 11, so that the unfixed end of the buffer spring plate 11 slides against the support base plate 2; the elasticity of the buffer spring plate 11, together with the protective top plate 5, firmly fixes the display device 3.

[0047] In use, pull the extension plate 7 so that it slides out from the inside of the receiving groove 15, causing the positioning strip 8 to move away from the inside of the slot 10. Then rotate the extension plate 7 and the protective top plate 5 to expose the display device 3. Due to the elasticity of the buffer spring plate 11, when the protective top plate 5 is rotated and the display device 3 is exposed, the buffer spring plate 11 resets, pushing the display device 3 up. Then rotate and move the display device 3 out, aligning the positioning hole 12 on the extension plate 7 with the positioning hole 12 on the protective top plate 5, and use the positioning pin 13 to fix it through, controlling and adjusting the distance the extension plate 7 extends from the inside of the receiving groove 15. Support and engage the extension plate 7 with the positioning plate 14 on the back of the display device 3 to tilt and support the display device 3. Control the length of the extension plate 7 and the protective top plate 5 through different positioning holes 12, and then control and adjust the tilt angle of the display device for data display by selecting different positioning plates 14, thereby facilitating the data display work.
