Description

Technical Field

[0001] This application relates to the field of engineering surveying equipment technology, and more specifically, to a level instrument installation fixture and surveying system. Background Technology

[0002] A level is an instrument used to establish a horizontal line of sight and determine the height difference between two points on the ground. The principle is based on the principle of leveling to measure the height difference between ground points. The main components include a telescope, a tube level (or compensator), a vertical axis, a base, and leveling screws. Due to its accuracy and convenience, the level is widely used in engineering surveying.

[0003] Existing levels require a tripod for secure use. During use, the level needs to be threaded and secured using bolts on the tripod. After repeated use, traditional levels will experience wear on the threaded connection at the bottom of the level, making maintenance difficult. This can lead to loosening of the threaded connection at the bottom of the device when secured with bolts, resulting in the level not being effectively fixed and affecting the measurement results. Summary of the Invention

[0004] The purpose of this application is to provide a level instrument installation fixture and surveying system that can prevent the failure of the threaded connection of the level instrument body after long-term use and extend its service life.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a level instrument installation fixture, comprising: a mounting base for installing the level instrument, and an adapter base for connecting a tripod, wherein the adapter base is provided with an adapter block, and the bottom of the adapter block is provided with a threaded hole; The adapter has a through mounting hole in the thickness direction, and the adapter block is detachably snapped into the mounting hole; The adapter and the mounting base are separate. The bottom of the mounting base is connected to a leveling foot, which sits on the adapter.

[0006] In an optional embodiment, the adapter block is limited and snapped into the mounting hole by an elastic component, the elastic component including a compression spring mounted on the adapter block, a snap-fit ​​block being movably mounted on the adapter block, and the compression spring being disposed between the snap-fit ​​block and the adapter block.

[0007] In an optional embodiment, the adapter block is provided with a snap-fit ​​groove, and the snap-fit ​​block is movably installed in the snap-fit ​​groove by the compression spring. The snap-fit ​​block includes a shell-like structure with one end closed and the other end open. One end of the compression spring abuts against the inner sidewall of the snap-fit ​​block, and the other end extends out of the snap-fit ​​block and abuts against the groove wall of the snap-fit ​​groove.

[0008] In an optional embodiment, the adapter block includes a block structure, and the snap-fit ​​block and the snap-fit ​​groove each include mutually cooperating square structures; The snap-fit ​​block and the compression spring comprise two pairs, symmetrically arranged on the top of the adapter block.

[0009] In an optional embodiment, the top of the snap-fit ​​groove is provided with a slot, and the top of the snap-fit ​​block at the open portion is connected to a push-pull plate, which extends outward from the top of the slot and at least a portion protrudes from the adapter block.

[0010] In an optional embodiment, the mounting hole includes a square through hole that mates with the adapter block, the thickness of the adapter block is the same as the thickness of the adapter base, and the bottom wall of the adapter block is flush with the bottom wall of the adapter base.

[0011] In an optional embodiment, the square through hole is provided with snap-fit ​​slots on both sides for the snap-fit ​​block to be installed horizontally. The snap-fit ​​slots include flat-cut slots, the depth of which is greater than the height of the snap-fit ​​block. An internal hole is provided between the flat-cut slot and the solid part of the adapter, so that at least a part of the snap-fit ​​block can be inserted into the internal hole.

[0012] In an optional embodiment, both the adapter and the mounting base are triangular structures, and after installation, the adapter and the mounting base overlap vertically.

[0013] In an optional embodiment, a control unit is also included, wherein an angle sensor and an alarm device are provided on the mounting base, and the angle sensor and the alarm device are electrically connected to the control unit respectively.

[0014] Secondly, the present invention provides a surveying system, including a level, a tripod, and a level mounting fixture as described in any of the foregoing embodiments. The level is mounted on the mounting base, the mounting base is attached to the adapter base, and the tripod includes connecting bolts that engage with threaded holes on the adapter base.

[0015] By setting up a mounting base and an adapter, the level instrument can be mounted on the mounting base. The leveling feet at the bottom of the mounting base, combined with the leveling feet resting on the adapter, allow for leveling adjustment of the level instrument. During adjustment, the leveling feet can be adjusted to keep the level instrument relatively level, reducing the complexity of adjustments required for each application.

[0016] By setting an adapter block and mounting holes on the adapter base, and combining this with a threaded hole at the bottom of the adapter block and the detachable installation of the adapter block in the mounting hole, the adapter block can be directly replaced after the threaded hole is severely worn and the connection fails. Thus, a stable connection between the adapter base and the tripod can be achieved by directly replacing the adapter block.

[0017] The adapter serves to support the tripod and connect it to the level, meeting the requirements for leveling and convenient connection of the level. Importantly, by replacing the snap-fit ​​connector, smaller components can be discarded and replaced, reducing the impact of connection failure on operation and enhancing usability.

[0018] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] The level instrument installation fixture in this application is mainly used during the use of the level instrument. Specifically, by setting up detachable connection components, the connection components can be replaced when wear occurs at the connection points, so as to obtain a more reliable application connection with a small cost loss, and ensure the reliable connection and installation of the level instrument on the tripod.

[0026] See Figure 1 and combined Figures 2-4 The level instrument installation fixture in this application has a main structure including a mounting base 1 and an adapter 2. The mounting base 1 is mainly used to install the level instrument 6, while the adapter 2 is mainly used to connect the tripod, so that the adapter 2 can connect and install the level instrument 6 and the tripod.

[0027] In the existing structure of most levels, a mounting base is only set between the tripod and the level. The level is installed by connecting the mounting base to the tripod. However, because the threaded port on the level frequently connects with the stud on the tripod, the threaded connection is prone to failure.

[0028] In this application, by setting a detachable and replaceable adapter block 3 on the adapter 2 and setting the threaded hole 31 on the adapter block 3, the threaded connection structure can be updated by replacing only the adapter block 3 in the event of threaded connection failure. Thus, the effective connection between the adapter 2 and the tripod is ensured by replacing a small component.

[0029] Specifically, the threaded hole 31 is located at the bottom of the adapter block 3. Combined with the detachable connection between the adapter block 3 and the adapter seat 2, the tripod and the adapter seat 2 can be connected.

[0030] By providing a mounting hole 21 through the thickness direction of the adapter 2, the adapter block 3 can be detachably snapped into the mounting hole 21, improving the convenience of replacing the adapter block 3.

[0031] The adapter 2 and the mounting base 1 are set separately, which can facilitate the overlapping installation of the level instrument 6 and the mounting base 1 on the adapter 2. At the same time, the leveling support 11 connected to the bottom of the mounting base 1 can be used to level the mounting base 1 and the level instrument 6.

[0032] It should be noted that in this application, the level instrument 6 is installed horizontally on the mounting base 1. During use, the mounting base 1 can be leveled by adjusting the leveling feet 11, thereby adjusting the horizontal state of the level instrument 6, which facilitates operation and application.

[0033] In one specific embodiment, the adapter block 3 is locked in the mounting hole 21 by an elastic component. The adapter block 3 can be installed or detached from the mounting hole 21 by controlling the elastic component, thereby ensuring that the adapter block 3 and the adapter seat 2 cooperate stably and reliably in the elastic locking state, and that the adapter block 3 can be separated from the adapter seat 2 when the adapter seat 2 needs to be replaced.

[0034] The elastic component includes a compression spring 4 mounted on the adapter block 3. A snap-fit ​​block 5 is movably mounted on the adapter block 3. The compression spring 4 is disposed between the snap-fit ​​block 5 and the adapter block 3. Through the cooperation between the snap-fit ​​block 5 and the compression spring 4, the snap-fit ​​block 5 can be movably mounted on the adapter block 3, and the position of the snap-fit ​​block 5 on the adapter block 3 can be adjusted by the control of the compression spring 4.

[0035] Furthermore, based on the relative positional change between the snap-fit ​​block 5 and the adapter 2, the adapter block 3 can be positioned on the adapter 2 or the adapter block 3 can be relatively disengaged from the adapter 2.

[0036] Specifically, the locking block 5 on the adapter block 3 is limited by the locking groove 32 provided on the adapter block 3. The position of the locking block 5 on the locking groove 32 can be changed by controlling the compression spring 4. The locking block 5 is movably installed in the locking groove 32 by the compression spring 4. Specifically, the locking block 5 includes a shell-like structure with one end closed and the other end open, and is horizontally arranged in the locking groove 32 on the top of the adapter block 3. The locking groove 32 is an opening slot opened on the upper side wall of the adapter block 3. The locking block 5 is elastically limited by the compression spring 4 and installed between the locking groove 32 and the mounting hole 21 of the adapter seat 2. The opening of the locking block 5 is set towards the middle of the adapter block 3.

[0037] One end of the compression spring 4 abuts against the inner wall of the snap-fit ​​block 5, and the other end extends out of the opening of the snap-fit ​​block 5 and abuts against the groove wall of the snap-fit ​​groove 32.

[0038] With this configuration, under natural conditions, at least a portion of the snap-fit ​​block 5 can be pushed outwards towards the adapter block 3 by the elastic force of the compression spring 4, and abut against the snap-fit ​​slots 22 on both sides of the mounting hole 21. This achieves an installation relationship where the snap-fit ​​block 5 serves as an intermediate connector and partially engages with the adapter block 3 and the adapter seat 2. The adapter block 3 is then fixed to the adapter seat 2 by the elastic force of the compression spring 4.

[0039] When it is necessary to disassemble and replace the adapter block 3, the snap-fit ​​block 5 is pressed towards the middle of the adapter block 3, so that the pressing force overcomes the outward elastic force of the compression spring 4, and the snap-fit ​​block 5 moves towards the middle of the adapter block 3, breaking the abutment relationship between the snap-fit ​​block 5 and the snap-fit ​​slot 22 on the adapter seat 2, and the adapter block 3 is moved upward in the mounting hole 21, so as to realize the disassembly of the adapter block 3 on the adapter seat 2.

[0040] In another specific embodiment, the adapter block 3 includes a square structure, and the snap-fit ​​block 5 and the snap-fit ​​groove 32 respectively include mutually cooperating square structures. Through the square block and the square structure, on the one hand, it is convenient to open the snap-fit ​​groove 32, and on the other hand, it allows the snap-fit ​​block 5 to move in the square space, avoiding skewed jamming during the movement.

[0041] The snap-fit ​​block 5 and the compression spring 4 comprise two pairs, symmetrically arranged on the top of the adapter block 3. Furthermore, the snap-fit ​​block 5 and the compression spring 4 are in a one-to-one correspondence, symmetrically arranged on the top of the adapter block 3, with each compression spring 4 horizontally installed in the hollow snap-fit ​​block 5.

[0042] During disassembly, by pressing the locking blocks 5 on both sides in the center, the locking blocks 5 can be moved relative to the locking groove 32 and the mounting hole 21 towards the center of the adapter block 3, thereby ensuring that the adapter block 3 can be disengaged from the mounting hole 21.

[0043] Combination Figure 1 In order to facilitate operation, the snap-fit ​​block 5 is limited in the snap-fit ​​groove 32. The top of the snap-fit ​​groove 32 is provided with a slot 33. The top of the snap-fit ​​block 5 at the open part is connected to a push-pull plate 51. The push-pull plate 51 extends outward from the top of the slot 33, and at least a part of it protrudes from the adapter block 3.

[0044] The push-pull plate 51 facilitates the squeezing operation of the snap-fit ​​block 5. At the same time, combined with the fact that the lateral openings of the slot 33 and the snap-fit ​​groove 32 are not connected, the push-pull plate 51 can be limited on the slot 33 to prevent the snap-fit ​​block 5 from detaching from the snap-fit ​​groove 32.

[0045] In one preferred embodiment, the mounting hole 21 includes a square through hole that mates with the adapter block 3. The thickness of the adapter block 3 is the same as the thickness of the adapter seat 2. Preferably, when the adapter block 3 is installed in the mounting hole 21, the bottom wall of the adapter block 3 is flush with the bottom wall of the adapter seat 2, which facilitates the connection of the threaded hole 31 on the bottom wall of the adapter block 3 with the bolt on the tripod, and makes the top surface of the tripod fit against the bottom surface of the adapter block 3, ensuring that the adapter seat 2 is stably supported.

[0046] Based on the aforementioned mating relationship between the snap-fit ​​block 5 and the snap-fit ​​slot 22, the square through hole of the mounting hole 21 is provided with snap-fit ​​slots 22 on both sides for the snap-fit ​​block 5 to be installed horizontally. The snap-fit ​​slots 22 include flat-cut slots, the depth of which is greater than the height of the snap-fit ​​block 5, which can ensure that the snap-fit ​​block 5 can be reliably installed in the snap-fit ​​slots 22. Furthermore, from the perspective of enhancing the mating stability between the snap-fit ​​block 5 and the adapter block 3, an internal hole 23 is provided between the flat-cut slot and the solid part of the adapter 2, so that at least a part of the snap-fit ​​block 5 can extend into the internal hole 23.

[0047] Specifically, under the elastic force of the compression spring 4, at least a portion of the closed end of the snap-fit ​​block 5 can extend into the internal hole 23, thereby forming a snap-fit ​​block 5 that is simultaneously lodged between the internal hole 23 and the snap-fit ​​groove 22. That is, the snap-fit ​​block 5 is simultaneously lodged in the internal hole 23 and the snap-fit ​​groove 32, which can effectively limit the snap-fit ​​block 5 to be installed on the adapter 2.

[0048] When the snap-fit ​​block 5 is pressed and centered by the push-pull plate 51, the snap-fit ​​block 5 can be disengaged from the internal hole 23 and snap-fit ​​groove 32 at the same time. After the snap-fit ​​block 5 is disengaged from the internal hole 23, the adapter block 3 can be lifted up and disengaged from the mounting hole 21 and the snap-fit ​​groove hole 22.

[0049] In this application, both the adapter 2 and the mounting base 1 are triangular structures. After installation, the adapter 2 and the mounting base 1 overlap vertically. The corresponding angles of the vertical overlap enhance the support of the adapter 2 for the upper structure.

[0050] Based on the horizontal adjustment of the mounting base 1 described above, further to ensure its levelness, the mounting base 1 is also equipped with an angle sensor 12 and an alarm device 13. The angle sensor 12 and the alarm device 13 are electrically connected to the control unit. When the angle sensor 12 detects a certain tilt angle in the mounting base 1, it sends an angle signal to the control unit, which then feeds back to the alarm device 13, reminding the operator to perform a leveling operation in the form of an audible and visual alarm, ensuring that the level instrument 6 is always operated in a level state.

[0051] The leveling instrument installation fixture in this application can effectively avoid the impact of threaded connection structure failure during frequent threaded connections.

[0052] This application also provides a surveying system, including a level 6, a tripod, and the aforementioned level mounting fixture. The level 6 is mounted on the mounting base 1, and the mounting base 1 is attached to the adapter base 2. The tripod includes connecting bolts, and the connecting bolts are engaged with threaded holes 31 on the adapter base 2.

[0053] Mounting base 1 can be detachably attached to adapter base 2 via leveling support 11. Adapter base 2 cooperates with tripod via detachable adapter block 3, which greatly facilitates operation and application, and can fundamentally avoid the problem of screw failure caused by frequent threaded connections.

[0054] A receiving groove 14 is also provided on the top of the mounting base 1. A cover plate 15 is connected to the receiving groove 14. A magnetic frame 16 is provided in the receiving groove 14. Through the cooperation of the magnetic frame 16 and the cover plate 15, the cover plate 15 can be opened and closed on the receiving groove 14, which can facilitate the collection of necessary tools in the surveying process and give it a storage function.

[0055] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
