Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping instruments, and particularly relates to an anti-loosening safety locking mechanism for a surveying and mapping tripod. Background Art

[0002] A tripod is a support frame used to stabilize cameras and surveying instruments to achieve certain photographic effects. The positioning of the tripod is very important. Tripods can be classified into wooden, high-strength plastic, and aluminum alloy materials according to their materials. Tripods are often indispensable in photography, such as star trail shooting, flowing water shooting, night scene shooting, macro shooting, etc.

[0003] However, the locking mechanisms of current tripods on the market can only control the expansion of the tripod at a fixed angle, which is likely to affect the applicable range of the tripod. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an anti-loosening safety locking mechanism for a surveying and mapping tripod, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: an anti-loosening safety locking mechanism for a surveying and mapping tripod, including a support seat. Tripods are arranged in an array below the support seat. A locking mechanism is arranged inside the tripod. The locking mechanism includes: a mounting seat, a telescopic sleeve, and a mounting slider. A movable seat is installed on the outside of the mounting seat corresponding to the end of the telescopic sleeve. A winding roller is installed on the lower surface of the mounting seat. A tensioning rope is arranged outside the winding roller. A rotating shaft is installed between the winding roller and the mounting seat. A ratchet gear is installed on the outer side of the upper end of the rotating shaft. A ratchet pawl is installed on the lower surface of the mounting seat on one side of the ratchet gear.

[0006] As a further scheme of the utility model: a hook is installed at the end of the tensioning rope, and a snap ring is arranged at the position corresponding to the hook below the mounting slider.

[0007] As a further scheme of the utility model: an extension frame is installed inside the tripod, and a locking bolt is installed on the outer side of the lower end of the tripod.

[0008] As a further scheme of the utility model: a sliding groove is installed inside the tripod corresponding to the position of the mounting slider, and the mounting slider is slidably connected with the sliding groove.

[0009] As a further scheme of the utility model: the winding roller and the ratchet gear are movably connected with the mounting seat through the rotating shaft, and the ratchet pawl is engaged with the ratchet gear.

[0010] As a further solution of the present utility model: The snap ring is fixedly connected to the mounting slider.

[0011] As a further solution of the present utility model: The telescopic sleeve is rotatably connected to the movable seat.

[0012] As a further solution of the present utility model: The tripod is rotatably connected to the support seat, and the extension frame is movably connected to the tripod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] With the cooperation of the telescopic sleeve and the mounting slider, the overall locking mechanism can be controlled at different mounting positions inside the deployed tripod, realizing the limit fixation of different unfolding angles of the tripod, so as to adapt to different usage scenarios.

[0015] The overall mounting slider can achieve a directional limiting effect inside the sliding groove. At the same time, by winding the tensioning rope to apply a force to the mounting slider towards the central position of the mounting seat, the stability of the unfolding of the tripod can be ensured.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, this embodiment provides a loosening-preventing safety locking mechanism for a surveying tripod, including a support base 1. Below the support base 1, a tripod 2 is arranged in an array. Inside the tripod 2, a locking mechanism 4 is arranged. The locking mechanism 4 includes: a mounting base 401, a telescopic sleeve 402, and a mounting slider 404. A sliding groove 3 is mounted inside the tripod 2 at a position corresponding to the mounting slider 404. The mounting slider 404 is slidably connected to the sliding groove 3. An activity seat 403 is mounted outside the mounting base 401 corresponding to the end of the telescopic sleeve 402. The telescopic sleeve 402 is rotatably connected to the activity seat 403. A winding roller 406 is mounted on the lower surface of the mounting base 401. A tensioning rope 405 is arranged outside the winding roller 406. A rotating shaft is mounted between the winding roller 406 and the mounting base 401. A ratchet gear 407 is mounted outside the upper end of the rotating shaft. The winding roller 406 and the ratchet gear 407 are movably connected to the mounting base 401 through the rotating shaft. A ratchet pawl 408 is mounted on the lower surface of the mounting base 401 on one side of the ratchet gear 407. The ratchet pawl 408 is engaged with the ratchet gear 407.

[0023] As Figures 2-4 shown, in this embodiment, a hook 410 is mounted at the end of the tensioning rope 405. A snap ring 409 is arranged below the mounting slider 404 at a position corresponding to the hook 410. The snap ring 409 is fixedly connected to the mounting slider 404. An extension frame 5 is mounted inside the tripod 2. The extension frame 5 is movably connected to the tripod 2. A locking bolt 6 is mounted outside the lower end of the tripod 2. The tripod 2 is rotatably connected to the support base 1.

[0024] The working principle of the present utility model is as follows: When in use, by controlling the overall unfolding angle as needed, the locking mechanism 4 is pushed as a whole inside the sliding groove 3 towards the position of the extension frame 5, and multiple telescopic sleeves 402 are pulled outwards as a whole to the same length. The extension frame 5 is pulled out from inside the tripod 2 as a whole, and the locking bolt 6 is used to position the tripod 2 and the extension frame 5, so as to move the three tripods 2 under the support base 1 outwards as a whole to the same angle. By applying torque to the winding roller 406 under the mounting base 401 as a whole, the winding roller 406 and the ratchet gear 407 are driven to rotate under the action of the rotating shaft, and the tensioning rope 405 connected to the three hooks 410 is wound on the outer side of the winding roller 406. With the cooperation of the ratchet pawl 408, it is ensured that the tensioning rope 405 exerts a pulling force on the movable seat 403, thus ensuring the stability when the three tripods 2 are unfolded.

[0025] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
