[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.
[0020] Please see Figure 1 - Figure 4This utility model provides an embodiment of an engineering surveying theodolite, including a support 1, a base 2 on the top of the support 1, a theodolite 3 fixedly connected to the top surface of the base 2, a connecting assembly 4 between the base 2 and the support 1, the connecting assembly 4 including a connecting sleeve 41 fixedly connected inside the support 1, a connecting port 42 on the bottom surface of the base 2, grooves 43 evenly distributed on the surface of the connecting sleeve 41, L-shaped blocks 44 evenly distributed inside the connecting sleeve 41, an arc groove 45 on one end surface of the L-shaped blocks 44, and first compression springs 46 symmetrically fixedly connected to the end surface of the L-shaped blocks 44 away from the arc groove 45, and mounting plates 47 fixedly connected relative to each other between the inner walls of the connecting sleeve 41. Guide rods 48 are symmetrically fixedly connected between the surfaces. Second compression springs 49 are fitted onto the surfaces of the guide rods 48. A pushing assembly 400 is installed inside the connecting sleeve 41. A rainproof assembly 5 is installed on the surface of the theodolite 3. The pushing assembly 400 includes a push rod 401 installed inside the connecting sleeve 41. A connecting plate 402 is fixedly connected to the surface of the push rod 401. A pull rod 403 is rotatably connected to the bottom surface of the push rod 401. A locking plate 404 is fixedly connected to the surface of the pull rod 403. A locking groove 405 is formed on the bottom surface of the connecting sleeve 41. The base 2 is slidably connected to the surface of the connecting sleeve 41 through the connecting port 42. L-shaped locking blocks 44 are slidably connected inside the sliding groove 43. The top surface of the push rod 401 abuts against the arc-shaped groove 4. On the surface of 5, the other end of the first compression spring 46 is fixedly connected to the inner wall surface of the connecting sleeve 41, the bottom surface of the L-shaped locking block 44 abuts against the top surface of the base 2, the connecting plate 402 is slidably connected to the surface of the guide rod 48, the second compression spring 49 is fixedly connected between the opposing surfaces of the connecting plate 402 and the bottom mounting plate 47, and the top surface of the top mounting plate 47 abuts against the bottom surface of the L-shaped locking block 44, providing guidance and support for the L-shaped locking block 44, so that the L-shaped locking block 44 and the slide groove 43 are always on the same horizontal line, ensuring that the L-shaped locking block 44 can slide smoothly inside the slide groove 43. The L-shaped locking blocks 44 are all the same size, and when the top rod 401 moves down, all L-shaped locking blocks 44 can retract synchronously into the connecting sleeve 4. Inside the base 1, the L-shaped locking blocks 44 do not interfere with each other when retracted into the connecting sleeve 41. The locking plate 404 and the locking slot 405 are mutually compatible. The bottom of the connecting sleeve 41 is open. Through the setting of the connecting component 4, the connection between the base 2 and the bracket 1 becomes extremely fast and stable. Under the action of the first compression spring 46, the L-shaped locking blocks 44 can automatically adapt to the insertion of the base 2 and achieve a firm lock through the pushing action of the push rod 401, which greatly improves the installation efficiency. When it is necessary to disassemble the theodolite 3, simply pull down the pull rod 403 to release the pushing action of the push rod 401 on the L-shaped locking blocks 44, so that the L-shaped locking blocks 44 retract into the connecting sleeve 41, and the base 2 can easily slide out, realizing quick disassembly and facilitating equipment maintenance and replacement.The upward compressive force of the second compression spring 49 on the connecting plate 402 ensures that the push rod 401 maintains its pushing position against the L-shaped locking block 44 when no external force is applied, providing double protection for the connection and enhancing its stability. The locking plate 404 and the locking groove 405 effectively prevent the pull rod 403 from rotating accidentally during operation, ensuring the stability of the pushing assembly 400 and improving the safety of equipment use. Due to the ease of connection and disassembly, this theodolite can be quickly deployed to the surveying site, improving work efficiency.
[0021] Please see Figure 1 - Figure 4 The rainproof component 5 includes mounting blocks 51 that are fixedly connected to the surface of the theodolite 3. Guide grooves 52 are formed through the surfaces of the mounting blocks 51, and locking grooves 53 are formed on opposite surfaces of the mounting blocks 51. Locking bolts 54 are provided on opposite surfaces of the mounting blocks 51. Support rods 55 are provided inside each mounting block 51. A rainproof plate 56 is fixedly connected to the top surfaces of two support rods 55. The ends of the support rods 55 away from the rainproof plate 56 are slidably connected to the inside of the guide grooves 52. The ends of the locking bolts 54 near the guide grooves 52 are threaded into the inside of the locking grooves 53 and abut against the support rods 55. The rainproof component 5 allows the rainproof plate 56 to be flexibly adjusted in height according to actual needs. By sliding the support rod 55 in the guide groove 52, the rainproof plate 56 can be easily raised or lowered to meet the needs of use under different weather conditions. The cooperation between the locking bolt 54 and the locking groove 53 ensures that the rainproof plate 56 can be firmly locked after being adjusted to the appropriate position, effectively preventing wind and rain from corroding the theodolite 3, protecting the accuracy and lifespan of the equipment. When not in use, the rainproof plate 56 can be lowered to the lowest position and fits tightly against the theodolite 3, further reducing space occupation and improving the portability of the equipment.
[0022] Working Principle: During the installation of the theodolite support 1 and the theodolite 3, the theodolite 3 is first slidably inserted into the surface of the connecting sleeve 41 through the connecting port 42 at the bottom of the base 2. At this time, under the action of the first compression spring 46, the arc groove 45 of the L-shaped locking block 44 abuts against the top surface of the top rod 401. The L-shaped locking block 44 is pushed up by the top rod 401 and slides along the sliding groove 43 until the bottom surface of the L-shaped locking block 44 abuts against the top surface of the base 2, thus fixing the base 2 and the connecting sleeve 41. The second compression spring 49 always applies an upward compressive force to the connecting plate 402, ensuring that the top rod 401 can maintain the pushing state of the L-shaped locking block 44 when no external force is applied. The setting of the locking plate 404 and the locking groove 405 allows the locking plate 404 to be locked inside the locking groove 405 under the pushing action of the top rod 401 on the L-shaped locking block 44. This prevents the pull rod 403 from rotating accidentally during operation and ensures the stability of the jacking assembly 400. If the theodolite 3 needs to be disassembled, the pull rod 403 is pulled down, and the jacking rod 401 moves down accordingly, releasing the jacking action on the L-shaped locking block 44. Under the reset action of the first compression spring 46, the L-shaped locking block 44 retracts into the connecting sleeve 41, and the base 2 can slide out of the connecting sleeve 41 to achieve disassembly. If used on a rainy day, the rainproof plate 56 is raised to a suitable position, and then the locking bolt 54 is tightened so that it abuts against the surface of the support rod 55, thereby fixing the position of the rainproof plate 56. The rainproof plate 56 is connected to the mounting block 51 through the support rod 55. The support rod 55 slides in the guide groove 52 to realize the lifting and lowering adjustment of the rainproof plate 56. When rain protection is not needed, the locking bolt 54 is loosened and the rainproof plate 56 is lowered to the lowest position to reduce space occupation.
