Description

Technical Field

[0001] This utility model belongs to the field of surveying equipment technology, specifically relating to a surveying instrument that is easy to adjust. Background Technology

[0002] Surveying instruments, simply put, are instruments and devices designed and manufactured for data acquisition, processing, and output in surveying operations. They include various instruments used for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry, required for surveying work during the planning, design, construction, and operation management phases of engineering projects.

[0003] Existing surveying instruments are generally used with tripods for support. Most of these instruments are connected to the tripods by a snap-fit ​​mechanism. When adjusting the height of the surveying instrument, the only way to do so is to adjust the support angle of the tripod. This method of height adjustment will cause the surveying instrument to deviate from its horizontal position, requiring recalibration. It is not possible to adjust the height without adjusting the front of the tripod support legs. Therefore, we propose a surveying instrument that is easy to adjust. Utility Model Content

[0004] The purpose of this invention is to provide a surveying instrument that is easy to adjust, so as to solve the problem mentioned in the background art that the surveying instrument is not convenient enough when adjusting the height.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable surveying instrument, comprising a surveying instrument, an eyepiece fixed to one side of the surveying instrument, a mounting base fixed to the bottom of the surveying instrument, a fixed base at the top of the mounting base, a tripod at the bottom of the fixed base, a height-adjustable mechanism between the fixed base and the tripod, a dustproof mechanism at the end of the eyepiece, and the height-adjustable mechanism comprising: a lifting component and a locking component.

[0006] Preferably, the lifting assembly includes a lifting slot extending through the center of the top of the tripod and a lifting rod fixed to the bottom of the fixed base, wherein the lifting rod is slidably connected to the lifting slot.

[0007] Preferably, a guide groove is formed through the surface of the lifting rod, and a guide block is fixed inside the lifting groove, with the guide block engaging with the guide groove.

[0008] Preferably, the surface of the fixed base is symmetrically fixed with operating handles.

[0009] Preferably, the locking assembly includes locking holes symmetrically and evenly spaced on both sides of the lifting rod, and threaded holes symmetrically penetrate both sides of the inner wall of the lifting groove.

[0010] Preferably, the tripod has symmetrically provided built-in grooves on both sides that connect to the screw holes. The built-in grooves are provided with locking rods that pass through the screw holes and connect to the locking holes. The locking rods are screwed into the locking holes for fixed connection.

[0011] Preferably, the dustproof mechanism includes a dustproof sleeve fitted onto the end of the eyepiece, with rubber blocks symmetrically fixed to the inner wall of the dustproof sleeve, and rubber rings fitted and fixed to the surface of the dustproof sleeve.

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

[0013] This invention, through its designed lifting groove, lifting rod, guide groove, guide block, and operating handle, enables the adjustment of the surveying instrument's height without adjusting the tripod support legs, eliminating the need for recalibrating the level. Furthermore, the designed locking holes, screw holes, internal groove, and locking rod securely lock the height-adjusted surveying instrument. Compared to existing technologies, this invention greatly simplifies the height adjustment of the surveying instrument. Attached Figure Description

[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 Figures 1 to 4 This utility model provides a technical solution: an easily adjustable surveying instrument, including a surveying instrument 1, an eyepiece fixed on one side of the surveying instrument 1, a mounting base 2 fixed at the bottom of the surveying instrument 1, a fixed base 3 at the top of the mounting base 2, a tripod 4 at the bottom of the fixed base 3, a height-adjustable mechanism between the fixed base 3 and the tripod 4, and a dustproof mechanism at the end of the eyepiece. The height-adjustable mechanism includes a lifting component and a locking component.

[0021] In this embodiment, preferably, the lifting assembly includes a lifting groove 100 that runs through the center of the top of the tripod 4 and a lifting rod 101 fixed to the bottom of the fixed base 3. The height of the surveying instrument 1 can be adjusted by sliding the lifting rod 101 and the lifting groove 100.

[0022] In this embodiment, preferably, a guide groove 200 is provided through the surface of the lifting rod 101, and a guide block 201 is fixed inside the lifting groove 100, and the guide block 201 is engaged with the guide groove 200.

[0023] In this embodiment, preferably, the surface of the fixed base 3 is symmetrically fixed with operating handles 300, which facilitates holding and operating the testing instrument 1 to adjust its height.

[0024] In this embodiment, preferably, the locking assembly includes locking holes 400 symmetrically opened at equal intervals on both sides of the lifting rod 101, and screw holes 401 symmetrically opened through both sides of the inner wall of the lifting groove 100.

[0025] In this embodiment, preferably, the tripod 4 has symmetrically provided built-in grooves 500 on both sides that are connected to the screw holes 401. The built-in grooves 500 are provided with locking rods 501 that pass through the screw holes 401 and are connected to the locking holes 400. The locking rods 501 are screwed and fixedly connected to the locking holes 400, which facilitates locking and positioning of the adjusted lifting rod 101.

[0026] In this embodiment, preferably, the dustproof mechanism includes a dustproof sleeve 600 fitted onto the end of the eyepiece, with rubber blocks 601 symmetrically fixed to the inner wall of the dustproof sleeve 600, and a rubber ring 602 fitted and fixed to the surface of the dustproof sleeve 600, which can protect the eyepiece.

[0027] The working principle and usage of this utility model are as follows: When it is necessary to adjust the height of the surveying instrument 1, first loosen the locking rods 501 inside the built-in grooves 500 on both sides of the tripod 4, so that their ends are screwed into the screw holes 401 from inside the locking holes 400. This releases the locking and positioning of the lifting rod 101. Then, hold the operating handle 300 and lift the fixed base 3 upwards, causing the lifting rod 101 to slide upwards inside the lifting groove 100. At the same time, the guide groove 200 moves on the surface of the guide block 201 to provide guidance, thereby raising the surveying instrument 1 to adjust its height. Once the surveying instrument 1 is adjusted to the appropriate height, stop moving the operating handle 300, and then tighten the locking rod 501 so that it rotates inside the screw hole 401 and engages with the corresponding locking hole 400 to secure it. This locks the position of the lifting rod 101, completing the adjustment. When the surveying instrument 1 needs to be used, first hold the dust cover 600, using the rubber ring 602 for gripping and anti-slip. Then pull the dust cover 600 to cause the rubber block 601 to be squeezed and separated from the eyepiece, allowing the dust cover 600 to be removed from the end of the eyepiece. Then the surveying instrument 1 can be used.

[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
