[0002] The surveying instrument generally includes a surveying instrument body, a support platform for supporting the surveying instrument body, and a bracket arranged at the lower end of the support platform. Usually, surveying work is carried out outdoors, and sunlight exposure may cause damage to the surveying instrument.

[0003] In order to solve the above problems, Chinese patent CN220623476U discloses a surveying instrument, including a fixed plate, a connecting seat and a surveying instrument body, wherein the fixed plate is fixedly connected to a second bearing inside, the second bearing is fixedly connected to a rotating column inside, the top of the rotating column is fixedly installed with a mounting plate, the top of the mounting plate is fixedly connected to a rebound assembly, the rebound assembly includes an arc column, the outer sleeve of the arc column is provided with a first spring, and one end of the first spring is fixedly connected to a movable plate. The above device drives the shielding cloth to move along the arc column through the movable plate, shielding the surveying instrument body placed on the mounting plate to avoid sunlight exposure and protect the surveying instrument body. However, when the arc column is hit and offset or bumped, the movable plate will not be able to smoothly drive the shielding cloth to move along the arc column, and the shielding effect on the surveying instrument body is lost. Utility Model Content

[0004] The purpose of the utility model is to provide a surveying and mapping instrument in view of the above-mentioned technical problems, which is provided with a foldable supporting component, which can cooperate with a shielding member and a fixing part arranged on both sides to shield the surveying and mapping device on the supporting table. When shielding is not required, the supporting component can be folded to reduce the occupied space and avoid collision damage.

[0005] In view of this, the utility model provides a surveying and mapping instrument, including a bracket, a supporting table is arranged on the top of the bracket, a surveying and mapping device is arranged on the supporting table, and also includes a supporting component arranged on the top of the supporting table, the supporting component is foldable, and fixed parts are arranged on both sides of the supporting table. The shielding member can be connected to the fixed parts on both sides and is supported by the supporting member, so as to form a shielding space on the supporting table to accommodate the surveying and mapping device.

[0006] In the present technical solution, a foldable supporting component is arranged on the top of the supporting table. When in use, the shielding member is connected to the fixed parts on both sides of the supporting table and is supported by the supporting component, which can fully shield the surveying and mapping device arranged on the supporting table. When there is no need to shield or the surveying and mapping device is removed from the supporting table, the supporting component can be folded to reduce the occupied space and avoid damage caused by collision during transportation. The shielding member is not limited to sun shading, but can also be used to block rain.

[0007] In the above technical solution, further, the support tabletop includes a fixed table and a support plate. The fixed table is rotatably connected to the support plate, and the bottom of the support plate is connected to a bracket.

[0008] In this technical solution, the fixed table and the support plate are rotatably connected. When the angle of the surveying and mapping device needs to be adjusted, the adjustment can be carried out by rotating the fixed table. The support member and the fixed part are both arranged on the fixed table and can move along with the fixed table, without the need to re-adjust the surveying and mapping device itself and the shielding member covering the surveying and mapping device. For the specific rotational connection method, refer to the patent document with the publication number CN220623476U, which describes the rotational connection between the mounting plate and the fixed plate. This application will not elaborate further.

[0009] In the above technical solution, further, the support member includes a first support rod and a second support rod. The first support rod is rotatably connected to the first support seat, and the second support rod is rotatably connected to the second support seat. The first support seat and the second support seat are fixedly arranged on the fixed table, and the first support rod and the second support rod can support the shielding member above the surveying and mapping device.

[0010] In this technical solution, the corresponding support rod and the support seat are both rotatably connected through a damping rotating shaft, and the angle of the support rod can be freely adjusted manually to ensure proper support of the shielding member.

[0011] In the above technical solution, further, both the first support rod and the second support rod are in a "C" - shaped structure, surrounding the surveying and mapping device. The two ends are respectively rotatably connected to the correspondingly arranged support seats. When the second support rod is flipped, it can pass through the lower part of the first support rod in the supporting state.

[0012] In this technical solution, the "C" - shaped support rod can fully support the shielding member above the surveying and mapping device. When the shielding member needs to be supported, first flip the first support rod to be perpendicular to the fixed table (i.e., the top - supporting state), and then flip the second support rod. The second support rod can pass through the lower part of the first support rod, making full use of the surface space of the fixed table. When both the first support rod and the second support rod are perpendicular to the fixed table, the height of the second support rod is lower than that of the first support rod, and the shielding member supported on the two support rods is in an inclined state, which can prevent rainwater from accumulating and causing the shielding member to sink between the two support members.

[0013] In the above technical solution, further, a clamping seat is also included. The clamping seat is fixedly arranged on the fixed table corresponding to the support rod in the horizontal state. The clamping seat includes a base fixedly arranged on the fixed table, and symmetric support walls are arranged on the top of the base. The support walls form a receiving groove for clamping the support rod.

[0014] In the technical solution, when the shielding member is not needed for shielding, the support rod is placed horizontally, and the top of the support rod is clamped in the receiving groove of the clamping seat to fix the support rod, thereby fully limiting the position of the support rod.

[0015] In the above technical solution, further, the fixing part includes a fixing plate slidably connected to the side slide groove of the fixing platform, the fixing plate and the bottom wall of the slide groove are elastically connected, in the non-stretched state, the fixing plate is partially exposed from the slide groove, and the fixing plate is provided with a fixing opening on the opening side of the slide groove.

[0016] In the above technical solution, further, the shielding member includes a shielding cloth, and hooks are provided on both sides of the shielding cloth corresponding to the fixing parts.

[0017] In the present technical solution, the hook and the fixing part are correspondingly arranged at 4 places, and the fixed plate partially exposes the slide groove, so that the fixed plate is pulled out when fixing the shielding member, and is fixed by passing the hook through the fixing opening set on the fixed plate. Because the hook passes through, the fixed plate will not be pulled back into the slide groove by the compression spring. When no shielding is needed, the hook is moved out of the fixing opening, the compression spring is restored, and the fixed plate is retracted into the slide groove.

[0018] In the above technical solution, further, a thickened cloth block is provided on the inner side of the shielding cloth, and the thickened cloth block and the hook are elastically connected by an elastic rope.

[0019] In the technical solution, the hook and the elastic rope are elastically connected, so that when the shielding cloth is fixed, the shielding cloth can be stretched to a more straight state to prevent rainwater from accumulating on the shielding cloth.

[0020] In the above technical solution, further, a storage box is provided at the bottom of the support table, and the storage box can accommodate the shielding member.

[0021] The beneficial effects of the utility model are:

[0022] 1. A foldable support component is provided on the top of the support table. When in use, the shielding component is connected to the fixed parts on both sides of the support table and supported by the support component, which can fully shield the surveying and mapping device arranged on the support table. When there is no need to shield or the surveying and mapping device is removed from the support table, the support component can be folded to reduce the occupied space and avoid damage caused by collision during transportation. The shielding component is not limited to sunshade, but can also block rain;

[0023] 2. The corresponding support rods and support seats are rotatably connected through a damping shaft, and the angle of the support rods can be freely adjusted manually to ensure appropriate support for the shielding member;

[0024] 3. The support rod with a "C" shape can fully support the shielding member above the surveying and mapping device. When the shielding member needs to be supported, first flip the first support rod to be perpendicular to the fixed platform (i.e., the top support state), and then flip the second support rod. The second support rod can pass through the lower part of the first support rod, making full use of the surface space of the fixed platform. When both the first support rod and the second support rod are perpendicular to the fixed platform, the height of the second support rod is lower than that of the first support rod. The shielding member supported on the two support rods is in an inclined state, which can prevent rainwater from accumulating and causing the shielding member to sink between the two support members.

[0038] First embodiment:

[0039] like Figure 1-6 As shown, this embodiment provides a surveying instrument, including a bracket 1, a support table 2 is arranged on the top of the bracket 1, a surveying device 3 is arranged on the support table 2, and a support component 4 is arranged on the top of the support table 2, the support component 4 is foldable, and fixed parts 7 are arranged on both sides of the support table 2. The shielding member 8 can be connected to the fixed parts 7 on both sides and supported by the support component 4, so as to form a shielding space for accommodating the surveying device 3 on the support table 2. A foldable support component 4 is arranged on the top of the support table 2. When in use, the shielding member 8 is connected to the fixed parts 7 on both sides of the support table 2 and supported by the support component 4, so as to fully shield the surveying device 3 arranged on the support table 2. When there is no need to shield or the surveying device 3 is removed from the support table 2, the support component 4 can be folded to reduce the occupied space and avoid damage caused by collision in the case of transportation. The shielding member 8 is not limited to sunshade, but can also be used to block rain.

[0040] like Figure 1 As shown, the support table 2 includes a fixed table 5 and a support plate 6, the fixed table 5 is rotatably connected to the support plate 6, and the bottom of the support plate 6 is connected to the bracket 1. The fixed table 5 and the support plate 6 are rotatably connected. When the surveying and mapping device 3 needs to be adjusted in angle, it can be adjusted by rotating the fixed table 5. The support component 4 and the fixing part 7 are both arranged on the fixed table 5 and can move with the fixed table 5. There is no need to readjust the surveying and mapping device 3 itself and the shielding member 8 blocking the top of the surveying and mapping device 3. The specific rotatable connection method is shown in the patent document with publication number CN220623476U. The rotatable connection of the mounting plate and the fixed plate 17 in the document will not be repeated in this application.

[0041] like Figure 1 and Figure 2 As shown in Figure 2 , the support member 4 includes a first support rod 9 and a second support rod 10. The first support rod 9 is rotatably connected to the first support base 11, and the second support rod 10 is rotatably connected to the second support base 12. The first support base 11 and the second support base 12 are fixedly arranged on the fixed platform 5. The first support rod 9 and the second support rod 10 can support and hold the shielding member 8 above the surveying and mapping device 3. The corresponding support rods and support bases are all rotatably connected through damping rotating shafts, and the angles of the support rods can be freely adjusted manually to ensure proper support and hold of the shielding member 8.

[0042] As Figure 1 and Figure 2 shown in Figure 2 , both the first support rod 9 and the second support rod 10 are in a "C"-shaped structure, surrounding the surveying and mapping device 3 and rotatably connected to the corresponding support bases at both ends. When the second support rod 10 flips, it can pass through the lower part of the first support rod 9 in the support and hold state. The "C"-shaped support rods can fully support and hold the shielding member 8 above the surveying and mapping device 3. When the shielding member 8 needs to be supported, first flip the first support rod 9 to be perpendicular to the fixed platform 5 (i.e., the top support state), and then flip the second support rod 10. The second support rod 10 can pass through the lower part of the first support rod 9, making full use of the surface space of the fixed platform 5. When both the first support rod 9 and the second support rod 10 are perpendicular to the fixed platform 5, the height of the second support rod 10 is lower than that of the first support rod 9. The shielding member 8 supported on the two support rods is in an inclined state, which can prevent rainwater from accumulating and causing the shielding member 8 to sink between the two support members.

[0043] As Figure 1-3 shown in Figure 1-3 , it further includes a clamping seat 13. The clamping seat 13 is fixedly arranged on the fixed platform 5 corresponding to the support rod in the horizontal state. The clamping seat 13 includes a base 14 fixedly arranged on the fixed platform 5. At the top of the base 14, support walls 15 are symmetrically arranged, and the support walls 15 form a receiving groove 16 for clamping the support rod. When the shielding member 8 does not need to be shielded, place the support rod horizontally and clamp the top of the support rod in the receiving groove 16 of the clamping seat 13 to fix the support rod and fully limit the support rod.

[0044] As Figure 1 and Figure 4 shown in Figure 4 , the fixing part 7 includes a fixing plate 17 slidably connected to the side groove 18 of the fixed platform 5. The fixing plate 17 is elastically connected to the bottom wall of the groove 18. In the non-stretched state, a part of the fixing plate 17 is exposed from the groove 18, and the fixing plate 17 is provided with a fixing opening 20 on the side of the opening 19 of the groove 18.

[0045] As Figure 2 、 Figure 5 and Figure 6As shown, the shielding member 8 includes a shielding cloth 22, and hooks 23 are provided on both sides of the shielding cloth 22 corresponding to the fixing part 7. The hooks 23 and the fixing part 7 are provided at 4 locations correspondingly, and the fixing plate 17 partially exposes the slide groove 18, so that the fixing plate 17 is pulled out when fixing the shielding member 8, and the fixing plate 17 is fixed by passing the hook 23 through the fixing opening 20 provided through the fixing plate 17. Because the hook 23 passes through, the fixing plate 17 will not be pulled back to the slide groove 18 by the compression spring 21. When shielding is not needed, the hook 23 is removed from the fixing opening 20, the compression spring 21 is restored, and the fixing plate 17 is retracted into the slide groove 18.

[0046] Recommended materials for the shielding cloth 22 are oxford cloth, nylon and polyester. The shielding cloth 22 made of these materials has the characteristics of water resistance, durability and sun protection, which can not only provide necessary physical protection, but also maintain the accuracy of the instrument and extend its service life in harsh outdoor environments.

[0047] A thickened cloth block 24 is provided on the inner side of the shielding cloth 22, and the thickened cloth block 24 and the hook 23 are elastically connected by an elastic rope 25. The hook 23 and the elastic rope 25 are elastically connected, and when the shielding cloth 22 is fixed, the shielding cloth 22 can be stretched to a more straight state to prevent rainwater from accumulating on the shielding cloth 22.

[0048] A storage box 26 is provided at the bottom of the support table 2 , and the storage box 26 can accommodate the shielding member 8 .

[0049] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
