Description

Technical Field

[0001] This utility model relates to the field of surveying instruments, specifically an assembled surveying instrument. Background Technology

[0002] A surveying instrument is a data acquisition, processing, and output instrument designed and manufactured for surveying operations. It is typically used in the planning, design, construction, and management phases of engineering projects for various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry. However, current surveying instruments have some shortcomings. When using a surveying instrument, it needs to be connected to a tray, and then the telescopic rod is installed under the tray. This is how the surveying instrument can be used. However, installing the surveying instrument and telescopic rod to the tray is relatively troublesome and cannot be completed quickly. When it is necessary to disassemble the surveying instrument, tray, and telescopic rod for separate storage, it takes a certain amount of time to disassemble them.

[0003] To address the aforementioned issues, a search revealed Chinese patent CN218327329U, which discloses a rapid assembly surveying instrument. The instrument includes a tray and a main body. The main body is embedded in the upper surface of the tray. Positioning clips are movably mounted on the upper surface of the tray and on both sides of the main body. A flip-up hanger is fixedly mounted on the lower surface of the tray near its edge. A telescopic rod is movably mounted inside the flip-up hanger, and release rods are movably mounted on both sides of the flip-up hanger.

[0004] Although the above-mentioned device can quickly position and clamp the surveyor body by pulling the positioning clamp away from the slot, causing the positioning clamp to compress the return spring during movement, and then quickly positioning and clamping the surveyor body by pulling the positioning clamp away from the slot after the rectangular embedding block is inserted into the slot, the return spring will lose its compressive force and push the positioning pin of the positioning clamp into the positioning groove of the rectangular embedding block. However, in actual use, when installing the surveyor body, it is necessary to pull the positioning clamp, which can easily pinch fingers when positioning and installing the surveyor body with one hand. Utility Model Content

[0005] The purpose of this invention is to provide an assembled surveying instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, an assembled surveying instrument is provided, comprising a surveying instrument body, a base fixedly mounted on the bottom of the surveying instrument body, an assembly plate mounted on the lower side of the base, the assembly plate including a connecting seat fixedly connected to the bottom of the base, a locking plate fixedly connected to the bottom of the connecting seat, the assembly plate mounted below the locking plate, the bottom of the assembly plate being supported and fixed by a tripod, and an installation space provided inside the assembly plate, with a locking spring installed inside the installation space.

[0007] Furthermore, the assembly plate includes a connecting seat, a locking plate, a positioning seat, a through hole, a locking groove, an installation space, a pressure seat, a locking spring, and a base plate. The bottom of the installation space is fixedly provided with a base plate, which is circular.

[0008] Furthermore, a locking spring is fixedly installed on the surface of the base plate, and a pressure seat is fixedly installed on the top of the locking spring. The pressure seat is a ring structure made of plastic.

[0009] Furthermore, the top of the installation space has a through-hole, which is linear, and the top wall surface of the installation space has a locking groove, the depth of which is equal to half the thickness of the top wall of the installation space.

[0010] Furthermore, the lock groove and the through hole are combined in a cross shape, the through hole and the lock groove are the same size, the through hole is adapted to the size of the lock piece, and the lock piece passes through the through hole and squeezes the pressure seat.

[0011] Furthermore, both ends of the locking plate and the locking groove are arc-shaped. The locking plate is inserted into the installation space and rotated 90 degrees to lock into the inside of the locking groove. The assembly plate at the bottom of the surveying instrument body is fixed to the positioning seat by the locking plate and the locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This solution involves rotating the main body of the surveying instrument, causing the locking plate to rotate. When the locking plate moves to a position relative to the locking groove, a "click" sound is heard, indicating that the locking plate is locked inside the locking groove. Under the compression of the locking spring, the main body of the rotating surveying instrument is quickly assembled. It is then fixed by a tripod installed at the bottom of the assembly tray, facilitating the use of the equipment. The installation of the main body of the surveying instrument is simple and quick; simply selecting the main body completes the fixing work, preventing the occurrence of finger pinching.

[0014] 2. This solution, through the design of components such as locking plates and springs, satisfies the locking requirements without excessively increasing the size or weight of the equipment, making it easy to carry and transport. During installation, no forceful operation is required; fixation is achieved solely through rotation and the natural elasticity of the springs, reducing wear or damage to equipment components caused by forced assembly and extending the equipment's service life. This installation design balances convenience, stability, and practicality, making it ideal for surveying instruments and other equipment that require frequent movement and rapid setup.

[0023] Please see Figure 1-7 This utility model provides an assembled surveying instrument, including a surveying instrument body 1. A base 2 is fixedly installed on the bottom of the surveying instrument body 1. An assembly plate 3 is installed on the lower side of the base 2. The assembly plate 3 includes a connecting seat 31 fixedly connected to the bottom of the base 2. A locking piece 32 is fixedly connected to the bottom of the connecting seat 31. The assembly plate 3 is installed below the locking piece 32. The bottom of the assembly plate 3 is supported and fixed by a tripod. An installation space 35 is opened inside the assembly plate 3. A locking spring 37 is provided inside the installation space 35.

[0024] Furthermore, the assembly plate 3 includes a connecting seat 31, a locking plate 32, a positioning seat 33, a through hole 34, a locking groove 341, an installation space 35, a pressure seat 36, a locking spring 37, and a base plate 38. The bottom of the installation space 35 is fixedly provided with the base plate 38, which is circular.

[0025] A locking spring 37 is fixedly installed on the surface of the base plate 38, and a pressure seat 36 is fixedly installed on the top of the locking spring 37. The pressure seat 36 is a ring structure made of plastic.

[0026] The top of the installation space 35 has a through-hole 34, which is linear. The top wall surface of the installation space 35 has a locking groove 341, the depth of which is equal to half the thickness of the top wall of the installation space 35.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown: When installing the main body 1 of the surveying instrument, simply insert the locking plate 32 into the through-hole 34 and then rotate it. The installation process is convenient and efficient, requiring no complicated tools. Assembly can be completed simply by hand-rotating, reducing the time cost of tool preparation and operation. From "the locking plate 32 passing through the through-hole 34" to "hearing a 'click' sound after rotation to lock," the steps are intuitive and sequential, allowing operators to quickly master the process and reducing reliance on professional skills. The cooperative design of the locking plate 32 and the locking groove 341, combined with the squeezing action of the locking spring 37, forms a double fixation, ensuring that the main body 1 of the surveying instrument is not easily loosened or detached during use, thus guaranteeing stability during measurement. The "click" feedback design allows operators to directly confirm the locking status by sound, avoiding equipment shaking or measurement errors caused by improper installation. The compact assembly structure and the design of components such as locking plate 32 and springs meet the locking requirements without excessively increasing the size or weight of the equipment, making it easy to carry and transport. No forceful operation is required during installation; the equipment is fixed by rotation and the natural elasticity of the spring, reducing wear or damage to equipment components caused by forced assembly and extending the service life of the equipment. This installation design takes into account convenience, stability, and practicality, making it very suitable for surveying instruments and other equipment that require frequent movement and rapid setup.

[0028] Furthermore, the lock groove 341 and the through hole 34 are combined in a cross shape. The through hole 34 and the lock groove 341 have the same size. The through hole 34 is adapted to the size of the lock piece 32. The lock piece 32 passes through the through hole 34 and presses the pressure seat 36.

[0029] Both ends of the locking plate 32 and the locking groove 341 are arc-shaped. The locking plate 32 is inserted into the installation space 35 and rotated 90 degrees to lock into the locking groove 341. The assembly plate 3 at the bottom of the surveying instrument body 1 is fixed to the positioning seat 33 by the locking plate 32 and the locking groove 341.

[0030] Working principle: When installing the surveying instrument body 1, hold the surveying instrument body 1 in your hand. The locking plate 32 is installed on the lower side of the base 2 at the bottom of the surveying instrument body 1. Pass the locking plate 32 through the through hole 34 and insert it into the installation space 35. Press the pressure seat 36. At this time, the locking spring 37 is compressed. Rotate the surveying instrument body 1, causing the locking plate 32 to rotate. When the locking plate 32 moves to the relative position with the locking groove 341, you will hear a "click". This means that the locking plate 32 is locked in the locking groove 341. Under the compression of the locking spring 37, the rapid assembly of the rotating surveying instrument body 1 is completed. It is then fixed by the tripod installed at the bottom of the assembly plate 3, which facilitates the use of the equipment. The method of installing the surveying instrument body 1 is simple and quick. You only need to select the surveying instrument body 1 to complete the fixing work, which prevents the occurrence of finger pinching.
