Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of total station protective structures, specifically, to a total station protective structure. Background Technology

[0002] In fields such as engineering surveying and topographic mapping, total stations, as high-precision surveying instruments integrating optics, mechanics, and electronics, play a crucial role in ensuring the accuracy and efficiency of surveying work. However, existing methods for using and protecting total stations have significant shortcomings and are insufficient to meet the needs of complex working environments.

[0003] Currently, most total stations adopt a box-type storage and retrieval system, requiring them to be removed from their protective cases and placed on tripods or other supporting equipment during operation. Once removed, the total station loses the comprehensive protection of its case, making it highly susceptible to external factors such as wind, sand, rain, and impacts during field measurements. For example, in construction sites or mountainous areas with strong winds and sandstorms, dust can penetrate the total station, damaging optical lenses and precision mechanical components, reducing instrument accuracy. In rainy weather, rainwater can seep into the instrument, potentially causing short circuits and equipment malfunctions. Furthermore, construction sites are characterized by frequent personnel movement and numerous pieces of equipment; the lack of protection makes the total station vulnerable to impacts, causing instrument components to loosen or become damaged, affecting the accuracy of measurement data and increasing equipment maintenance costs and downtime.

[0004] With the increasing diversification of surveying and mapping scenarios, the need for protection during the use of total stations is becoming more and more urgent. The traditional "use and protection is lost" model has become a bottleneck restricting the reliability and service life of total stations. Therefore, developing a structure that can provide effective protection during the use of total stations has become the key to ensuring the smooth progress of surveying and mapping work and improving the durability of instruments. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a protective structure for a total station, which solves the technical problem in the prior art that the total station needs to be taken out of the protective case and placed on a tripod or other supporting equipment during operation, and once taken out, the total station loses the all-round protection of the case.

[0006] According to one aspect, at least one embodiment of this disclosure provides a total station protection structure, comprising:

[0007] A main cover and a secondary cover, wherein the main cover and the secondary cover are slidably connected;

[0008] The total station body and connecting components are provided. The total station body is fixed inside the bottom of the main cover, and the connecting components are disposed between the main cover and the auxiliary cover.

[0009] A limiting and fixing component is disposed outside the main cover and the secondary cover;

[0010] An open component, wherein the open component is disposed on the main cover;

[0011] The connecting assembly includes several connecting rods, which are fixed to the upper end of the inner surface of the main cover. The connecting rods are movably connected to the secondary cover. A pair of sleeves are provided at the bottom of the main cover, and a pair of rectangular rods are provided at the bottom of the secondary cover. One end of the rectangular rods is movably fitted inside the sleeves.

[0012] As a further technical solution, a screw is rotatably connected inside the sleeve on one side. The screw is connected to the rectangular rod by a threaded connection. One end of the screw is located on the outside, and a screwing block is provided at one end of the screw.

[0013] As a further technical solution, the open component includes a window, which is opened on the top of the main cover and the adjacent side. An unfolding plate is rotatably connected to the window via a pin. The unfolding plate has an overall L-shaped structure and is sealed and fitted to the inner end face of the window.

[0014] As a further technical solution, a pair of sleeve blocks are provided at one end of the top of the main cover. The sleeve blocks have slots. A pair of fixed ears are provided at the top of the main cover. A movable rod is rotatably connected in the fixed ears. A locking block is provided at one end of the movable rod. One end of the movable rod passes through the slots. The locking block is attached to the side end face of the sleeve block.

[0015] As a further technical solution, the limiting and fixing component includes a pair of locking blocks, which are fixed at both ends of the side surface of the secondary cover. Stabilizing blocks are provided at both ends of the surface of the main cover. A limiting bracket is movably connected inside the stabilizing block, and a spring is fitted on the limiting bracket.

[0016] As a further technical solution, the top of the unfolding plate is provided with several through holes, which are movably connected to the connecting rod.

[0017] As a further technical solution, a handle is provided on the top of the unfolding plate.

[0018] As a further technical solution, both the main cover and the secondary cover have a C-shaped structure.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] In this disclosure, the connecting assembly, through the movable assembly of the connecting rod and the secondary cover, as well as the cooperation of the sleeve, rectangular rod, and screw, enables convenient connection and separation of the main cover and the secondary cover. The threaded drive of the screw can precisely adjust the position of the secondary cover, ensuring a tight fit between the two to form a protective unit, preventing the total station from being exposed to the external environment during use, and solving the problem of loss of protection upon removal in existing technologies. Disassembly only requires rotating the screw block to separate the secondary cover, facilitating equipment maintenance and operation, and improving the practicality and flexibility of the protective structure.

[0033] like Figures 1-4 As shown, it illustrates a total station protection structure according to an embodiment of this disclosure, comprising:

[0034] A main cover 1 and a secondary cover 2, wherein the main cover 1 and the secondary cover 2 are slidably connected;

[0035] The total station body 3 and the connecting component 4 are provided. The total station body 3 is fixed inside the bottom of the main cover 1, and the connecting component 4 is disposed between the main cover 1 and the secondary cover 2.

[0036] A limiting and fixing component 6 is disposed outside the main cover 1 and the secondary cover 2;

[0037] Open component 5, the open component 5 being disposed on the main cover 1;

[0038] The connecting assembly 4 includes several connecting rods 4-1. The connecting rods 4-1 are fixed to the upper end of the inner surface of the main cover 1. The connecting rods 4-1 are movably connected to the secondary cover 2. The bottom of the main cover 1 is provided with a pair of sleeves 4-2. The bottom of the secondary cover 2 is provided with a pair of rectangular rods 4-3. One end of the rectangular rod 4-3 is movably fitted inside the sleeve 4-2. A screw 4-4 is rotatably connected inside one side of the sleeve 4-2. The screw 4-4 is connected to the rectangular rod 4-3 by a threaded engagement. One end of the screw 4-4 is located on the outside. A screwing block 4-5 is provided at one end of the screw 4-4.

[0039] In some examples, a connecting component 4 is designed to achieve a detachable connection between the main cover 1 and the secondary cover 2. This component includes several connecting rods 4-1 located on the upper part of the inner surface of the main cover 1, serving as the basic component for connecting the main cover 1 and the secondary cover 2. The connecting rods 4-1 and the secondary cover 2 are movably fitted together, allowing the secondary cover 2 to slide along the axial direction of the connecting rods 4-1, thereby adjusting the relative position of the main cover 1 and the secondary cover 2. A pair of sleeves 4-2 at the bottom of the main cover 1 and a pair of rectangular rods 4-3 at the bottom of the secondary cover 2 cooperate with each other. A screw 4-4 is rotatably connected inside one of the sleeves 4-2, and is tightly engaged with the movable rod 5-6 through threads. When the operator rotates the screw block 4-5 at one end of the screw 4-4, the rotation of the screw 4-4 is converted into linear motion of the rectangular rod 4-3 within the sleeve 4-2 through thread transmission, thereby causing the secondary cover 2 to move left and right relative to the main cover 1. This design not only ensures a tight connection between the secondary cover 2 and the main cover 1, guaranteeing a stable bond between the two in the protective state and providing reliable protection for the total station body 3; but also allows for easy separation of the secondary cover 2 from the main cover 1 by rotating the screw block 4-5 in the opposite direction to disengage the movable rod 5-6 from the sleeve 4-2 when the secondary cover 2 needs to be removed. This meets the needs of different scenarios such as maintenance and operation of the total station, greatly improving the flexibility and convenience of the protective structure.

[0040] like Figures 1-4As shown in the figure, the open component 5 in this embodiment includes a window 5-1, which is opened on the top of the main cover 1 and the adjacent side. An unfolding plate 5-2 is rotatably connected to the window 5-1 via a pin. The unfolding plate 5-2 has an overall L-shaped structure and is sealed to the inner end face of the window 5-1. A pair of sleeve blocks 5-3 are provided at one end of the top of the main cover 1. The sleeve blocks 5-3 have slots 5-4. A pair of fixing ears 5-5 are provided at the top of the main cover 1. A movable rod 5-6 is rotatably connected to the fixing ears 5-5. A locking block 5-7 is provided at one end of the movable rod 5-6. One end of the movable rod 5-6 passes through the slot 5-4, and the locking block 5-7 is attached to the side end face of the sleeve block 5-3.

[0041] In some examples, to achieve flexible opening and closing of the main cover 1, an opening component 5 is designed. This component includes windows 5-1 on the top and adjacent sides of the main cover 1, providing space for opening operations. An L-shaped unfolding plate 5-2, rotatably connected to the window 5-1 via a pin, can rotate around the pin. In the closed state, the unfolding plate 5-2 seals tightly against the inner end face of the window 5-1, effectively preventing external dust and moisture from entering the main cover 1, thus providing good protection for the total station body 3. A pair of sleeve blocks 5-3 are provided at one end of the top of the main cover 1. The slots 5-4 inside these blocks cooperate with the movable rod 5-6 and the locking block 5-7 at one end of the fixed lug 5-5. When it is necessary to open one side of the main cover 1, rotate the movable rod 5-6 to disengage the locking block 5-7 from the slot 5-4, and then easily rotate the unfolding plate 5-2 to open the window 5-1, facilitating the operator's observation, debugging, and other operations on the total station. After use, rotate the unfolding plate 5-2 back to its original position to ensure a tight seal between the unfolding plate 5-2 and the window 5-1. Then rotate the movable rod 5-6 to insert the locking block 5-7 into the slot 5-4, firmly fixing the unfolding plate 5-2 and restoring the protective performance of the main cover 1, ensuring that the total station is properly protected when not in use.

[0042] like Figures 1-4 As shown in the figure, the limiting and fixing component 6 in this embodiment includes a pair of locking blocks 6-1. The locking blocks 6-1 are fixed at both ends of the side surface of the auxiliary cover 2. Stabilizing blocks 6-2 are provided at both ends of the surface of the main cover 1. A limiting bracket 6-3 is movably connected inside the stabilizing block 6-2. A spring 6-4 is fitted on the limiting bracket 6-3.

[0043] In some examples, to ensure a stable connection between the main cover 1 and the secondary cover 2 when closed, a limiting and fixing assembly 6 is designed. This assembly includes a pair of locking blocks 6-1 fixed at both ends of the side surface of the secondary cover 2, which correspond to the stabilizing blocks 6-2 at both ends of the surface of the main cover 1. A limiting insert 6-3, movably fitted within the stabilizing block 6-2, can extend and retract within the stabilizing block 6-2. A spring 6-4 fitted on the limiting insert 6-3 provides elastic support. When the main cover 1 and the secondary cover 2 are closed, pushing the limiting insert 6-3 inserts it into the locking block 6-1. The elastic force generated by the spring 6-4 under compression causes the limiting insert 6-3 to tightly engage with the locking block 6-1, firmly connecting the main cover 1 and the secondary cover 2 together. This effectively prevents separation under external impact, vibration, or other conditions, providing reliable protection and fixation for the total station body 3. When it is necessary to open the main cover 1 and the secondary cover 2, simply pull the limiting bracket 6-3 outward to overcome the elastic force of the spring 6-4 and make it disengage from the locking block 6-1, thereby releasing the locking state of the main cover 1 and the secondary cover 2. The operation is simple and the connection is stable, meeting the dual needs of opening and closing and fixing of the protective structure in actual use.

[0044] For example, such as Figure 1 As shown, the top of the unfolding plate 5-2 has several through holes 7, and the through holes 7 are movably connected to the connecting rod 4-1.

[0045] In some examples, several perforations 7 are made inside the top of the unfolding plate 5-2 and are connected to the connecting rod 4-1 in a movable assembly. This connection maintains the strength of the unfolding plate 5-2 during connection, preventing wobbling. The cooperation between the perforations 7 and the connecting rod 4-1, along with the sealed fit structure, enhances the protective performance and prevents external debris from entering the main cover 1.

[0046] For example, such as Figure 1 As shown, the top of the unfolding plate 5-2 is provided with a handle 8.

[0047] In some examples, the handle 8 located at the top of the unfolding plate 5-2 provides a convenient point of leverage for the operator. Whether opening the unfolding plate 5-2 for total station operation or ensuring a tight seal when closing it, the handle 8 makes operation easier and less strenuous.

[0048] For example, such as Figure 1 As shown, both the main cover 1 and the secondary cover 2 have a C-shaped structure.

[0049] In some examples, the C-shaped structure allows the main cover 1 and the secondary cover 2 to fit together and form a single box, which can maintain a tight seal and protection during transport.

[0050] In actual use: Fix the total station body 3 inside the bottom of the main cover 1, with the bottom of the total station body 3 exposed to the outside, allowing it to be connected to the bracket. Slide the auxiliary cover 2 along the connecting rod 4-1 inside the main cover 1, so that the rectangular rod 4-3 at the bottom of the auxiliary cover 2 is inserted into the sleeve 4-2 at the bottom of the main cover 1. Rotate the screw block 4-5 outside one side of the sleeve 4-2, and the screw 4-4 will rotate, causing the rectangular rod 4-3 to move inside the sleeve 4-2 until the auxiliary cover 2 and the main cover 1 are tightly fitted. Next, rotate the movable rod 5-6 at the top of the main cover 1, causing the locking block 5-7 to disengage from the slot 5-4 of the sleeve block 5-3. Rotate the L-shaped unfolding plate 5-2 around the pin, opening the windows 5-1 on the top and sides of the main cover 1 to expose the operating parts of the total station. In use, push the limiting bracket 6-3 to pull it out of the locking block 6-1 of the auxiliary cover 2, and then turn the screw block 4-5 to drive the auxiliary cover 2 outward to open. After use, close the unfolding plate 5-2 to seal it against the window 5-1. Rotate the movable rod 5-6 to insert the locking block 5-7 into the slot 5-4 to fix the unfolding plate 5-2. Rotate the screw block 4-5 in the opposite direction to control the secondary cover 2 to move back and close it. Then insert the limiting bracket 6-3 into the locking block 6-1 to complete the disassembly and storage of the protective structure.
