Description

Technical Field

[0001] This utility model relates to the field of surveying instruments, and in particular to a surveying instrument with support optimization. Background Technology

[0002] In the field of surveying, the total station is a highly integrated, high-tech measuring instrument that combines optical, mechanical, and electronic technologies, making it an indispensable piece of equipment in modern surveying engineering. A total station can not only accurately measure angles (including horizontal and vertical angles) but also distances (including slope distance, horizontal distance, and elevation difference), and its built-in microprocessor can calculate the three-dimensional coordinates of target points in real time. This versatility has led to the widespread application of total stations in various fields such as topographic surveying, engineering layout, construction, and geological exploration. Whether conducting large-scale topographic surveying or precise layout work on construction sites, the total station provides efficient and accurate measurement data, greatly improving the efficiency and precision of surveying work.

[0003] The support structure of a total station refers to the devices or components specifically designed to fix, stabilize, and ensure the normal operation of the total station. This support structure typically includes a tripod, base, and leveling screws, among other parts. Its main function is to ensure that the total station remains in a level and stable state during various surveying operations, thereby significantly improving the accuracy and reliability of the measurements.

[0004] A typical tripod provides support and initial leveling at the working position, with final leveling achieved via leveling screws. Tripods are bulky and cannot perform fine-tuning of length, resulting in a complex support structure for the surveying instrument while also lacking functionality. Utility Model Content

[0005] The main purpose of this utility model is to provide a surveying instrument with optimized support, which aims to solve the problems of existing surveying instrument tripods occupying a large volume and being unable to achieve fine length adjustments, resulting in a complex support structure and a lack of functionality.

[0006] To achieve the above objectives, this utility model provides a support-optimized surveying instrument, comprising: The base has at least three threaded holes evenly arranged around its circumference. The length direction of the threaded holes is inclined from bottom to top and points towards the central axis of the base. The length direction of the threaded holes forms an angle of 15 to 30 degrees with the vertical direction. Multiple support legs are provided, corresponding to multiple threaded holes. Each support leg includes a threaded head and a support tube that are connected to each other. The threaded head and the threaded hole form a threaded engagement. The end of the support tube away from the threaded head is detachably provided with a foot cone. The dimensions of the support tubes of the multiple support legs decrease in order to form a nestable engagement. The surveying instrument body is detachably mounted on the base, wherein the angle of the surveying instrument body is adjustable when mounted on the base.

[0007] Furthermore, the foot cone is connected to the side wall of the support tube.

[0008] Furthermore, the connection method between the foot cone and the support tube is plug-in, connectable, or bolted connection, etc.

[0009] Furthermore, the foot cone is inserted into the support tube and is made of polymer material, and the foot cone has a gradually decreasing outer diameter at one end corresponding to the support tube.

[0010] Furthermore, the base includes a base body and a plurality of feet connected to the outer periphery of the base body, and the threaded holes are provided on the feet.

[0011] Furthermore, the main body of the seat and the foot are connected by a connecting structure.

[0012] Furthermore, the number of supporting legs is three.

[0013] Furthermore, the support leg is made of stainless steel or aluminum.

[0014] Furthermore, the threaded hole penetrates the base.

[0015] Furthermore, a horizontal indicator is provided on the base.

[0016] The optimized surveying instrument provided by this utility model, in its storage state, has both the instrument body and support legs disassembled and attached to the base, with multiple support legs sequentially nested together to minimize space occupation. When the surveying instrument needs to be used, the multiple support legs stored in the nest are disassembled, and the threaded ends of the support legs are connected to the threaded holes of the base. The base can be leveled by adjusting each support leg. The support legs have a simple structure and are convenient for storage and use. Attached Figure Description

[0021] Reference Figures 1 to 5 In one embodiment of this utility model, a support-optimized surveying instrument includes: The base 100 has at least three threaded holes 110 evenly arranged in the circumference. The length direction of the threaded holes 110 is inclined from bottom to top and points towards the central axis of the base 100. The length direction of the threaded holes 110 forms an angle of 15 to 30 degrees with the vertical direction. Multiple support legs 200 are provided corresponding to multiple threaded holes 110. Each support leg 200 includes a threaded head 210 and a support tube 220 connected to each other. The threaded head 210 and the threaded hole 110 form a threaded engagement. A foot cone 230 is detachably provided at the end of the support tube 220 away from the threaded head 210. The size of the support tube 220 of the multiple support legs 200 decreases to form a sleeve-fitting engagement. The surveying instrument body 300 is detachably installed on the base 100, wherein the angle of the surveying instrument body 300 is adjustable when installed on the base 100.

[0022] In the current technology, the tripod of a total station provides support and initial leveling in the working position, and final leveling is achieved through the leveling screw. The tripod occupies a large volume and cannot achieve fine length adjustments, which results in a complex support structure for the surveying instrument and a lack of functionality.

[0023] The optimized surveying instrument provided by this utility model has a fixed up-down direction during use, thus providing directional indication via up-down movement. The base 100 has at least three threaded holes 110 evenly distributed circumferentially. The number of threaded holes 110 is preferably three or four. The length direction of the threaded holes 110 slopes upwards towards the central axis of the base 100. The central axis of the base 100 is a physical axis; the base 100 is circular or polygonal in shape on a plane, and the central axis is its central axis. The length direction of the threaded holes 110 forms an angle of 15 to 30 degrees with the vertical direction. This restricts the angle setting of the threaded holes 110, thereby meeting typical usage conditions. If the angle of the threaded holes 110 is too small, the stability of the support legs 200 will be weak; if the angle of the threaded holes 110 is too large, the required length of the support legs 200 may be excessive. The base 100 can be made of metal or polymer.

[0024] Multiple support legs 200 are provided with multiple threaded holes 110. Each support leg 200 includes an interconnected threaded head 210 and a support tube 220. The threaded head 210 and the support tube 220 are either an integral structure or a connecting structure. A threaded engagement is formed between the threaded head 210 and the threaded hole 110. After the support leg 200 is connected to the base 100, the levelness of the base 100 can be adjusted by changing the degree of engagement between the threaded head 210 and the threaded hole 110. A foot cone 230 is detachably provided at the end of the support tube 220 away from the threaded head 210. The installation of the foot cone 230 on the support tube 220 protects the end face of the support tube 220 while also providing a foundation for stable support. The foot cone 230 can be installed on the support tube 220 by means of socketing, insertion, snap-fitting, or bolting. The dimensions of the support tubes 220 of the multiple support legs 200 decrease progressively, forming a nestable fit.

[0025] The surveying instrument body 300 is detachably mounted on the base 100. The angle of the surveying instrument body 300 is adjustable when mounted on the base 100. The method of fixing the surveying instrument body 300 on the base 100 can be varied and is not limited, and various methods in the prior art can be referred to.

[0026] During use, when in storage mode, the surveyor body 300 and support legs 200 are disassembled and attached to the base 100, and the multiple support legs 200 are sequentially nested together to minimize space occupation. When the surveyor needs to be used, the multiple nested support legs 200 are disassembled, and the threaded heads 210 of the support legs 200 are connected to the threaded holes 110 of the base 100. The base 100 is leveled by adjusting each support leg 200.

[0027] In summary, in the storage state, both the surveyor body 300 and the support legs 200 are disassembled and attached to the base 100, and the multiple support legs 200 are sequentially nested together, thereby minimizing space occupation. When the surveyor needs to be used, the multiple support legs 200 stored together are disassembled, and the threaded heads 210 of the support legs 200 are connected to the threaded holes 110 of the base 100. The horizontal adjustment of the base 100 is achieved by adjusting each support leg 200. The support legs 200 have a simple structure and are convenient for storage and use.

[0028] In one embodiment, the foot cone 230 is connected to the side wall of the support tube 220.

[0029] In this embodiment, the connection position of the foot cone 230 is set on the side wall of the support tube 220, so that different models of foot cone 230 are not required for support tubes 220 of different sizes. The connection method of the foot cone 230 on the support tube 220 can be various, such as plug-in, snap-fit ​​or bolt connection.

[0030] In one embodiment, the connection between the foot cone 230 and the support tube 220 is by plug-in, connectionable, or bolt connection, etc.

[0031] In this embodiment, the method of fixing the foot cone 230 is restricted, which has the advantages of convenient installation and stable use.

[0032] Reference Figure 4 In one embodiment, the foot cone 230 is inserted into the support tube 220 and is made of polymer material. The foot cone 230 has a gradually decreasing outer diameter at one end corresponding to the support tube 220.

[0033] In this embodiment, the foot cone 230 is limited to a polymer material, such as polyurethane, to provide a base for deformation. Simultaneously, the end of the foot cone 230 connected to the support tube 220 is designed to conform to the shape of the frustum, thus enabling fixation on support tubes 220 of different sizes.

[0034] Reference Figure 5 In one embodiment, the base 100 includes a base body 120 and a plurality of feet 130 connected to the outer periphery of the base body 120, and the threaded hole 110 is disposed on the feet 130.

[0035] In this embodiment, the threaded hole 110 is provided on the foot 130 to provide space for the adjustment head to work, and can also reduce the overall size of the base 100 and material consumption.

[0036] In one embodiment, the seat body 120 and the foot seat 130 are connected by a connection structure.

[0037] In this embodiment, considering that threaded holes 110 need to be machined on the foot 130, the base body 120 and the foot 130 are set as a connected structure rather than an integral structure, thereby facilitating the independent machining of the foot 130. The connection method between the base body 120 and the foot 130 can be bolt connection or welding, etc.

[0038] Reference Figure 5 In one embodiment, the number of support legs 200 is three.

[0039] In this embodiment, limiting the number of support legs 200 to three to form stable support reduces the complexity of the overall structure and controls costs. Furthermore, since multiple support legs 200 need to be interlocked during storage, an excessive number of support legs 200 would result in significant size differences and design difficulties.

[0040] In one embodiment, the support leg 200 is made of stainless steel or aluminum.

[0041] In this embodiment, the material of the support leg 200 is limited to stainless steel and aluminum, thereby providing structural strength while also offering weather resistance.

[0042] Reference Figure 5 In one embodiment, the threaded hole 110 penetrates the base 100.

[0043] In this embodiment, the threaded hole 110 penetrates the base 100, thereby increasing the height adjustment range of the support leg 200.

[0044] In one embodiment, a horizontal indicator is provided on the base 100.

[0045] In this embodiment, the level indicator device can guide the adjustment of the support leg 200, so that the base 100 meets the level requirements.

[0046] In summary, the optimized surveying instrument provided by this utility model, in its storage state, allows both the surveying instrument body 300 and the support legs 200 to be disassembled and attached to the base 100, with multiple support legs 200 sequentially nested together, thereby minimizing space occupation. When the surveying instrument needs to be used, the multiple nested support legs 200 are disassembled, and the threaded heads 210 of the support legs 200 are connected to the threaded holes 110 of the base 100. The horizontal adjustment of the base 100 is achieved by adjusting each support leg 200. The support legs 200 have a simple structure and are convenient for storage and use.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
