Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a protection structure for a total station instrument, including a total station instrument body 1, a mounting plate 2 provided on the total station instrument body 1, two side baffles 3 detachably provided on the mounting plate 2, and a top plate 4 for connecting the two side baffles 3. The side baffle 3 and the top plate 4 are detachably connected. The side baffle 3 is an inverted isosceles trapezoid structure. Two symmetrically arranged openings 41 are opened at both ends of the top plate 4. Sunshade baffles 5 are respectively rotatably connected to one side of the two openings 41 close to each other. An adjusting mechanism 6 for adjusting the flipping angle of the sunshade baffle 5 is provided on the top plate 4. Folding flaps 7 are provided between both sides of the sunshade baffle 5 and both sides of the opening 41 respectively.

[0027] During assembly, asFigure 1 As shown, the mounting plate 2 is fixed on the total station body 1 by screws. Then, the mounting plate 2, two side baffles 3 and the top plate 4 are assembled together in sequence to wrap the total station body 1 inside, thus playing the role of sunshading and rain shielding. During use, since the mounting angle of the objective lens on the total station body 1 is adjustable to measure the data of an object in its obliquely upper position. At this time, as Figure 2 shown, the mounting angle of the adjustable baffle 5 can be adjusted to avoid blocking the measurement field of view of the objective lens. Also, by setting the side baffle 3 as an inverted isosceles trapezoid structure, the range of sunshading and rain shielding can be increased, and the lower part of the side baffle 3 can be prevented from affecting the operation of the staff on the total station body 1.

[0028] It should be noted that the connection structure between the mounting plate 2 and the total station body 1 should be set according to the specific structure of the total station body 1. The connection structure can be set by opening threaded holes on the total station body 1, and the mounting plate 2 is fixed in the threaded holes by screws.

[0029] In a preferred embodiment, referring to Figure 3 、 4 , the adjusting mechanism 6 includes adjusting seats 61 symmetrically arranged on both sides of the corresponding opening 41 and a rotating shaft 62 for connecting the two adjusting seats 61. Two connecting ears 51 rotatably connected to the rotating shaft 62 are provided on the baffle 5. An arc-shaped groove 63 is opened on the adjusting seat 61, and a locking screw 64 slidably connected to the arc-shaped groove 63 is provided on the connecting ear 51. During adjustment, the baffle 5 swings upward around the rotating shaft 62, and the locking screw 64 slides along the direction of the arc-shaped groove 63 accordingly. After the adjustment is completed, the locking screw 64 is screwed in to fix the position of the baffle 5. By setting the baffle 5 with an adjustable mounting angle, the top plate 4 can be set with a large enough shielding area, and the staff's head can hide under the top plate 4 for sunshading. At the same time, the inclined baffle 5 can avoid blocking the measurement field of view of the objective lens of the total station body 1, ensuring the normal operation of the total station body 1.

[0030] Furthermore, referring to Figure 3 , L-shaped baffles 71 for accommodating the folding flap 7 are provided on both sides of the opening 41. When the baffle 5 is not opened, the folding flap 7 is stored in the L-shaped baffle 71 to play a role in protecting the folding flap 7. When the baffle 5 is opened, the folding flap 7 can be unfolded as the mounting angle of the baffle 5 increases, so as to achieve the purpose of side sunshading and prevent rainwater from seeping in through the gap between the baffle 5 and the top plate 4, thereby ensuring the rainproof effect.

[0031] In this embodiment, referring to Figure 3 , a rain shield 52 is provided on the side of the baffle 5 away from the opening 41. The rain shield 52 is perpendicular to the baffle 5, which can prevent rainwater from sliding down along the lower surface of the baffle 5 and causing rainwater to drip on the total station body 1.

[0032] After the measurement work is completed, to facilitate the storage of the protection structure of the present utility model, the installation plate 2 and the side baffle 3, as well as the side baffle 3 and the top plate 4, are detachably connected. They can be assembled when needed, and when not needed, detaching each connection structure is conducive to neatly storing the protection structure.

[0033] In addition, two shielding plates 5 are symmetrically arranged at both ends of the top plate 4 respectively, so that the top plate 4 has no specific installation direction, further improving the flexibility of using the protection structure.

[0034] In a preferred embodiment, referring to Figure 3 、 5 , it further includes a first locking mechanism 8. First clamping strips 42 are respectively arranged on both sides of the top plate 4, and an insertion part 31 inserted into the first clamping strips 42 is arranged at the top of the side baffle 3. The first locking mechanism 8 is used to lock and fix the first clamping strips 42 and the insertion part 31. When assembling one side baffle 3 and one side edge of the top plate 4, insert the insertion part 31 into the first clamping strips 42, and lock the relative positions of the first clamping strips 42 and the insertion part 31 through the first locking mechanism 8 to realize the assembly of the side baffle 3 and the top plate 4.

[0035] Furthermore, referring to Figure 5 , the first clamping strips 42 are of an n-shaped structure, and the insertion part 31 is of a u-shaped structure. The two sides of the first clamping strips 42 and the two sides of the insertion part 31 are staggered from each other to realize insertion. Through the above settings, the contact area between the first clamping strips 42 and the insertion part 31 can be adjusted, thereby improving the connection stability between the side baffle 3 and the top plate 4.

[0036] Preferably, the first clamping strips 42 and the insertion part 31 can slide relative to each other in the horizontal direction to facilitate adjusting the relative positions of the top plate 4 and the side baffle 3 to cope with different usage situations.

[0037] In this embodiment, referring to Figure 3 、 5, the first strip 42 is provided with a plurality of first positioning holes 421 arranged at equal intervals along its length direction. One side of the insertion part 31 is provided with a plurality of second positioning holes 311 arranged at equal intervals along its length direction. The distance between adjacent two first positioning holes 421 is the same as the distance between adjacent two second positioning holes 311. When different first positioning holes 421 correspond to the second positioning holes 311, the relative position of the top plate 4 on the side baffle 3 is adjusted; a plurality of first locking mechanisms 8 are slidably arranged on the other side of the insertion part 31. Each first locking mechanism 8 includes a first positioning post 81 that can be inserted into any one of the first positioning holes 421 and the second positioning holes 311. After the adjustment is completed, the first positioning post 81 is inserted into the corresponding first positioning hole 421 and the second positioning hole 311 to lock the position of the top plate 4 on the side baffle 3. Preferably, two first locking mechanisms 8 are provided between each side baffle 3 and the top plate 4 to ensure the stability of the connection between the two.

[0038] Further, the first locking mechanism 8 further includes a sliding seat 82. A sliding groove 312 extending along its length direction is opened on the other side of the insertion part 31. The sliding seat 82 is slidably connected to the sliding groove 312, and the first positioning post 81 is threadedly connected to the sliding seat 82. Move the sliding seat 82 to a position where one of the first positioning holes 421 is coaxial with the second positioning hole 311, and then screw in the first positioning post 81 so that the first positioning post 81 is inserted into the corresponding first positioning hole 421 and the second positioning hole 311 to lock the relative position of the side baffle 3 and the top plate 4. When the position of the top plate 4 needs to be adjusted, just screw out the first positioning post 81 out of the first positioning hole 421 and the second positioning hole 311, and then push the top plate 4 a certain distance so that another first positioning hole 421 corresponds to the second positioning hole 311, and then the first positioning post 81 can be screwed in again to lock the position of the top plate 4 again.

[0039] In a preferred embodiment, refer to Figure 6 , the bottom of the side baffle 3 is provided with a lower second strip 32. An installation groove 321 is opened on the second strip 32. The side of the installation plate 2 can be inserted into the installation groove 321, and the second strip 32 is fixedly connected to the installation plate 2 through a second locking mechanism 9. By providing the second strip 32 and the installation plate 2 to be inserted and connected, the detachable connection between the side baffle 3 and the installation plate 2 is realized, and under the action of the second locking mechanism 9, the connection stability between the side baffle 3 and the installation plate 2 is further improved. Preferably, two second locking mechanisms 9 are provided between each side baffle 3 and the installation plate 2.

[0040] Further, the second locking mechanism 9 includes a mounting seat 91 provided on the second clamping strip 32, a second positioning post 92 slidably connected to the mounting seat 91, and a spring 93 sleeved on the second positioning post 92. Both ends of the spring 93 abut against the mounting seat 91 and the shoulder of the second positioning post 92 respectively. The mounting plate 2 and the second clamping strip 32 are both provided with third positioning holes 21 adapted to the second positioning post 92. Specifically, the third positioning hole 21 on the second clamping strip 32 penetrates through the mounting groove 321. Under the elastic force of the spring 93, it is ensured that the second positioning post 92 is always inserted into the third positioning holes 21 on the mounting plate 2 and the second clamping strip 32. When disconnecting the connection between the side baffle 3 and the mounting plate 2, the second positioning post 92 is pulled outwards so that the second positioning post 92 is away from the third positioning hole 21 and the spring 93 is compressed. At this time, the side baffle 3 can be pulled out.

[0041] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
