Abstract

The present invention provides a surveying instrument based on special terrain and geography, which relates to the field of geographical surveying and comprises: a locking plate, wherein the locking plate is rotatably connected to the inside of an adjusting seat, and solves the problem that the tripod of the existing surveying instrument does not have a structure for rapid support, the support speed is extremely slow on special terrain, and the positioning and adjustment of the secondary support rod are achieved by bolts, and the problem of not having a fine-tuning structure is that the regulating component abandons the traditional bolt positioning method and adopts a threaded structure to achieve two adjustment methods of rapid adjustment and fine-tuning. During rapid adjustment, the adjusting rod is not restricted by the thread and can be freely extended and retracted, which is convenient for the use of rapid adjustment of the adjusting rod and the support length of a large span. At the same time, during fine adjustment, the adjusting rod can achieve slow adjustment under the action of the locking block thread, and can still be used for fine-tuning after the installation component is supported, and can be adapted to the rapid support of surveying instruments on different types of special terrains.

Description

Technical Field

[0001] The invention relates to the technical field of geographical surveying, and in particular to a surveying instrument based on special topography and geography. Background Art

[0002] When surveying and measuring topography, surveying instruments are needed. Common surveying instruments include theodolites, total stations and levels. Surveying instruments need to be used in conjunction with support frames. The support frames can support the surveying instruments flatly at a certain height for use, making it convenient for people to survey and measure topography.

[0003] However, as far as the existing surveying instruments used in topographic and geographical surveys are concerned, their tripods are difficult to set up, and there is no structure for quick setting up. The setting speed is extremely slow on special terrains. The positioning and adjustment of the secondary support rods are achieved through bolts, and there is no fine-tuning structure. At the same time, when setting up on special terrains, it is necessary to frequently change the length of the secondary support rods, so it is necessary to frequently turn the bolts for adjustment and positioning.

[0015] Beneficial Effects

[0016] 1. When the device is in use, the regulating component can realize the positioning and adjustment of the adjusting rod (i.e., the secondary support rod mentioned in the background technology). The operation is convenient and flexible. The traditional bolt positioning method is abandoned, and the threaded structure is adopted to realize two adjustment methods: quick adjustment and fine adjustment. During quick adjustment, the adjusting rod can be freely extended and retracted without being restricted by the thread, which is convenient for the use and support length of the adjusting rod for large spans. At the same time, during fine adjustment, the adjusting rod can realize slow adjustment under the action of the locking block thread, and it can still be used for fine adjustment after the installation component is supported. The operation is convenient and flexible, and can adapt to the rapid erection and support of surveying instruments on different types of special terrains. In the reset state, the use length of the adjusting rod can be automatically locked and positioned, ensuring that the installation component can play a stable supporting role for the measuring instrument, facilitating the staff to measure and use various geographical topographic data, and improving the flexibility, adaptability and practicality of the device.

[0017] 2. The device is in a fine-tuning state in the reset state. At this time, the control thread groove of the locking block cooperates with the rod body thread of the adjusting rod, so that under the locking action of the thread, the use length of the adjusting rod can be locked and positioned, which is convenient for transportation and can also provide stable support for the surveying instrument after support. In this mode, when the adjustment seat is rotated, the adjustment seat can drive the locking block to rotate synchronously through the limiting groove, so that the locking block can drive the adjusting rod to move up and down to fine-tune the use length through the control thread groove when rotating, which is convenient for precise leveling of the surveying instrument when supported and used, and the operation is convenient and flexible.

[0018] 3. When supported and used on special terrain, the regulating component can be used to achieve the needs of quickly and widely changing the use length of the adjusting rod. The above function can be achieved by pulling up the control ring. When the control ring is pulled up, the driving protrusion of the control ring can drive the locking plate to rotate through the driving groove, so that when the locking plate rotates, the locking control groove can drive the locking block to move outward to release the thread matching relationship between the control thread groove and the adjusting rod. Thereafter, the adjusting rod is released from the locked state and can be freely pulled and pulled to change the use length. When the required length is pulled out, after loosening the control ring, the control ring can drive the regulating component to reset and restore the locking relationship to the adjusting rod under the action of the locking top spring, so that the adjusting rod can be stably supported and used, with fast adjustment, easy use, and strong flexibility and adaptability.

[0019] 4. The lock control slot consists of a locking slot and an unlocking slot. In the reset state, the lock control rod is inserted into the locking slot and is away from one end of the unlocking slot. Since the center of the locking slot is on the rotation axis of the adjusting seat, and the movement trajectory of the locking block is limited by the limiting slot, the force direction of the locking block is perpendicular to the locking slot during fine-tuning, that is, the locking block will not move inside the locking slot when the adjusting seat rotates, resulting in the phenomenon of accidentally releasing the locking state of the adjusting rod, and the use is stable.

[0020] 5. Similarly, the groove body of the unlocking groove is an inclined arc. This design enables the locking rod to avoid inside the locking groove at the initial stage of the locking disc rotation without changing the lateral use position (i.e., the locking rod will not change position at this time). When the locking rod enters the unlocking groove from the locking groove, the inclined arc groove body of the unlocking groove can drive the locking block to move outward through the locking rod, thereby releasing the thread matching relationship between the control thread groove and the adjusting rod, that is, releasing the locking state of the adjusting rod, which is convenient for adjustment and flexible in use.

In this mode, when the adjusting seat 201 is rotated, the adjusting seat 201 can drive the locking block 204 to rotate synchronously through the limiting groove 2011, so that the locking block 204 can drive the adjusting rod 102 to move up and down through the control thread groove 2042 when rotating, and fine-tune the use length, which is convenient for precise leveling of the surveying instrument when supported and used, and the operation is convenient and flexible.

[0039] Among them, a locking rod 2041 is provided on the top of the locking block 204, and a locking groove 221 is provided inside the disk body of the locking disk 202, and the locking rod 2041 is inserted into the inside of the locking groove 221. In use, when it is supported and used on special terrain, the adjustment component 2 can be used to achieve the needs of quickly and widely changing the use length of the adjustment rod 102, and the above function can be achieved by pulling up the control ring 203. When the control ring 203 is pulled up, a driving protrusion 2031 is provided inside the ring body of the control ring 203, and a driving groove 2022 is provided at the bottom of the locking disk 202. The groove body of the driving groove 2022 is spiral, and the driving protrusion 2031 is inserted into the inside of the driving groove 2022. The driving protrusion 2031 of the control ring 203 can pass through the driving groove 2022 The locking plate 202 is driven to rotate, so that when the locking plate 202 rotates, the locking control groove 221 can drive the locking block 204 to move outward to release the threaded matching relationship between the control thread groove 2042 and the adjusting rod 102, so that the adjusting rod 102 can be released from the locked state and can be freely pulled out to change the use length. When the required length is pulled out, a locking top spring 2032 is provided on the top of the control ring 203, and the two ends of the locking top spring 2032 respectively abut against the top of the control ring 203 and the bottom of the locking plate 202. After loosening the control ring 203, the control ring 203 can drive the regulating component 2 to reset and restore the locking relationship with the adjusting rod 102 under the action of the locking top spring 2032, so that the adjusting rod 102 can be stably supported and used, with fast adjustment, easy use, and strong flexibility and adaptability.

[0040] Among them, a positioning groove 1021 is provided inside the rod body of the adjusting rod 102, and a positioning block 1011 is provided inside the frame body of the supporting frame 101, and the positioning block 1011 is inserted into the positioning groove 1021. During use, the positioning groove 1021 can limit the moving trajectory of the adjusting rod 102 through the positioning block 1011, so that the adjusting rod 102 will not be skewed, twisted or rotated during movement, causing the device to be stuck or the adjustment to fail, and the use is stable.

[0041] The locking control slot 221 is composed of a locking slot 2211 and an unlocking slot 2212, and the locking slot 2211 and the unlocking slot 2212 are connected end to end. The slot body shape of the locking slot 2211 is an arc, and the slot body shape of the unlocking slot 2212 is an inclined arc. The center position of the arc of the locking slot 2211 is on the same straight line as the center position of the adjusting rod 102, and the center position of the arc of the locking slot 2211 is located on the rotation axis of the adjusting seat 201. During use, in the reset state, the locking rod 2041 is inserted into the locking groove 2211 and is away from the end of the unlocking groove 2212. Since the center of the locking groove 2211 is located on the rotation axis of the adjustment seat 201, the adjustment seat 201 is provided with a limiting groove 2011, and the cross-sectional shape of the locking block 204 is a regular polygon, the locking block 204 is inserted into the limiting groove 2011, and the movement track of the locking block 204 is limited by the limiting groove 2011. The locking block 204 is restricted so that the force direction of the locking block 204 is perpendicular to the locking groove 2211 when fine-tuning, that is, when the adjustment seat 201 rotates, the locking block 204 will not move inside the locking groove 2211, resulting in the phenomenon of accidentally releasing the locking state of the adjustment rod 102. The use is stable, and the groove body of the unlocking groove 2212 is an inclined arc. This design enables the locking rod 2041 to be locked in the locking groove 2211 at the initial stage of the rotation of the locking disk 202 when the locking disk 202 rotates. 11 and will not change the lateral use position (that is, the locking rod 2041 will not change its position at this time). When the locking rod 2041 enters the unlocking groove 2212 from the locking groove 2211, the inclined arc groove body of the unlocking groove 2212 can drive the locking block 204 to move outward through the locking rod 2041, thereby releasing the thread matching relationship between the control thread groove 2042 and the adjusting rod 102, that is, releasing the locking state of the adjusting rod 102.

[0042] Among them, a track groove 2012 is provided inside the adjustment seat 201, and a track block 2033 with a "T"-shaped cross-section is provided on the side of the ring body of the control ring 203. The track block 2033 is inserted into the track groove 2012. During use, the track block 2033 can limit the moving trajectory of the control ring 203 through the track groove 2012, so that the control ring 203 will not be skewed or twisted during movement, causing the device to be stuck and fail, and it is stable to use.

[0043] Specific usage and function of this embodiment: In the present invention, the installation component 1 is first supported on the bottom surface through the regulating component 2, and the installation disk 103 is initially leveled before the surveying instrument is installed on the top of the installation disk 103. After that, the surveying of various terrain and geographical data can be started. When the installation component 1 is supported, the device is in a fine-tuning state in the reset state. At this time, the control thread groove 2042 of the locking block 204 cooperates with the rod body thread of the adjusting rod 102, so that under the locking action of the thread, the use length of the adjusting rod 102 can be locked and positioned, which is convenient for transportation and can also provide stable support for the surveying instrument after support. In this mode, when the adjusting seat 201 is rotated, the adjusting seat 201 can drive the limiting groove 2011 to The locking block 204 rotates synchronously, so that the locking block 204 can drive the adjusting rod 102 to move up and down to fine-tune the use length by controlling the threaded groove 2042 when rotating, which is convenient for precise leveling of the surveying instrument when it is supported and used. The locking control groove 221 is composed of a locking groove 2211 and an unlocking groove 2212. In the reset state, the locking control rod 2041 is inserted into the locking groove 2211 and is away from the end of the unlocking groove 2212. Since the center position of the groove body of the locking groove 2211 is on the rotation axis of the adjusting seat 201, and the movement trajectory of the locking block 204 is limited by the limiting groove 2011, the force direction of the locking block 204 is perpendicular to the locking groove 2211 during fine-tuning, that is, when the adjusting seat 201 rotates, the locking block 204 will not be in the locking groove 221 1, resulting in the phenomenon of accidentally releasing the locking state of the adjusting rod 102. When it is supported and used on special terrain, the adjusting rod 102 can be quickly and widely changed in use length through the regulating component 2. The above function can be achieved by pulling up the control ring 203. When the control ring 203 is pulled up, the driving protrusion 2031 of the control ring 203 can drive the locking plate 202 to rotate through the driving groove 2022. The groove body of the unlocking groove 2212 is an inclined arc. This design enables the locking rod 2041 to avoid inside the locking groove 2211 at the initial stage of the rotation of the locking plate 202 when the locking plate 202 is rotating, and the lateral use position will not be changed (that is, the locking rod 2041 will not change its position at this time). When the locking rod 2041 enters the unlocking groove 2212 from the locking groove 2211, the inclined arc groove body of the unlocking groove 2212 can drive the locking block 204 to move outward through the locking rod 2041, thereby realizing the release of the threaded matching relationship between the control thread groove 2042 and the adjusting rod 102. As a result, when the locking plate 202 rotates, the locking groove 221 can drive the locking block 204 to move outward to release the threaded matching relationship between the control thread groove 2042 and the adjusting rod 102. Thereafter, the adjusting rod 102 is released from the locked state and can be freely pulled out to change the use length. After the required length is pulled out, the control ring 203 can drive the control assembly 2 to reset and restore the locking relationship with the adjusting rod 102 under the action of the locking top spring 2032 after opening the control ring 203.This enables the adjustment rod 102 to be stably supported and used.
