Description

Technical Field

[0001] This utility model relates to the field of laser rangefinder technology, and in particular to a laser rangefinder that is easy to fix. Background Technology

[0002] An optical rangefinder is an instrument that measures the distance to a target by modulating a laser with a specific parameter. A laser rangefinder emits a single or a series of short pulsed laser beams to the target, then a photoelectric element receives the reflected laser light, and a timer measures the time from emission to reception to calculate the distance. Depending on the ranging method, laser rangefinders are divided into two types: phase-based and pulse-based. Phase-based rangefinders detect the distance by measuring the phase difference between the emitted and reflected light as they propagate through space; while pulse-based rangefinders calculate the distance by measuring the time required for a laser pulse to make one round trip.

[0003] Existing patent CN210835221U discloses a laser rangefinder, including a rangefinder body and a support base. A sphere is mounted on the upper end of the support base, and a clamping device is fitted onto the sphere, clamping it against the side wall of the sphere. The rangefinder body is mounted on the clamping device. The clamping device includes a housing and two spherical plates, which are positioned opposite each other and abut against the surface of the sphere. A guide rod is mounted on each of the two spherical plates, with its center line coinciding with the center of the sphere. The guide rods are slidably fitted within the housing, and a clamping assembly is connected to the guide rods. The clamping assembly includes an adjusting screw and a connecting piece. A rotating device is located at the upper part of the clamping device. This prior art facilitates leveling of the laser rangefinder.

[0004] However, in the aforementioned prior art, the process of adjusting the outriggers to extend and retract is very troublesome, which easily increases the labor intensity of the operator and makes it inconvenient to operate the device quickly. Utility Model Content

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-5 This utility model provides a laser rangefinder that is easy to fix, including a laser rangefinder body 1, a fixing base 2 and a support mechanism. The laser rangefinder body 1 is disposed above the fixing base 2. The laser rangefinder body 1 used in this design is existing technology, and its structure will not be described in detail here.

[0021] In this specific embodiment, the support mechanism includes multiple support components and a motor 3. Each support component includes a C-shaped seat 4, a support cylinder 5, and two upright plates 6. A worm gear 7 is disposed within the C-shaped seat 4, and a driven gear 8 is disposed below the worm gear 7. A support rod 9 is slidably disposed within the support cylinder 5. A worm wheel 10 is hinged between the two upright plates 6, with both ends of the worm wheel 10 extending to the outer sides of the upright plates 6. A drive gear 11 is disposed at the output end of the motor 3. The C-shaped seat 4 is fixedly connected to the fixed base 2 and located below the fixed base 2. The support cylinder 5 is fixedly connected to the worm wheel 10 and located at both ends of the worm wheel 10. The two upright plates 6 are respectively connected to the fixed base 2. The worm gear 7 is fixedly connected and located below the fixed base 2. The worm 7 is driven by the worm wheel 10 and is located outside the worm wheel 10. The motor 3 is fixedly connected to the fixed base 2 and is located inside the fixed base 2. The driving gear 11 meshes with the corresponding driven gear 8 and is located among the multiple driven gears 8. The motor 3 drives the driving gear 11 to rotate, and the driving gear 11 drives the multiple driven gears 8. The worm gear 7 rotates under the action of the driven gears 8, and the worm wheel 10 drives the support cylinder 5 to automatically unfold and retract, thereby reducing the labor intensity of the operator and allowing the device to quickly complete the fixed placement operation.

[0022] The support mechanism further includes a conical cylinder 12, which is fixedly connected to the fixed base 2 and located in the lower middle part of the fixed base 2. The conical cylinder 12 is also sleeved on the output end of the motor 3. The setting of the conical cylinder 12 can facilitate the improvement of the stability of the output end of the motor 3 when rotating, thereby ensuring that the driving gear 11 can stably output to the multiple driven gears 8.

[0023] Secondly, an electric push rod 13 is provided on the outside of the support cylinder 5, and a fixing block 14 is provided on the support rod 9. The fixing block 14 is fixedly connected to the electric push rod 13 and is located at the output end of the electric push rod 13. The electric push rod 13 can facilitate the automatic extension and retraction of the length of the support rod 9 within the support cylinder 5, thereby improving the practicality of the device.

[0024] Furthermore, the laser rangefinder that is easy to fix also includes multiple anti-slip sleeves 15. The multiple anti-slip sleeves 15 are respectively bonded to the corresponding support rods 9 and are sleeved on the end of the support rods 9 away from the support cylinder 5. The anti-slip sleeves 15 can improve the grip and thus avoid slipping.

[0025] In addition, a rotating sleeve 16 is provided below the laser rangefinder body 1, and a T-shaped circular block 17 is provided inside the rotating sleeve 16. A top cover 18 is threaded on the top of the fixed base 2. The T-shaped circular block 17 is fixedly connected to the top cover 18 and is located above the top cover 18. The laser rangefinder body 1 is also located on the top cover 18. When it is necessary to rotate the laser rangefinder body 1, simply rotate the rotating sleeve 16 so that the rotating sleeve 16 can rotate under the action of the T-shaped circular block 17. When it is necessary to disassemble the laser rangefinder body 1, simply rotate the top cover 18 so that the top cover 18 can be removed from the fixed base 2.

[0026] When using this utility model, by placing the device on the ground and starting the motor 3, the motor 3 drives the driving gear 11 clockwise. The driving gear 11 drives multiple driven gears 8, which in turn drive the worm 7 to rotate. The worm 7 then drives the worm wheel 10, which in turn drives the support cylinder 5 to unfold. Simultaneously, the electric push rod 13 is activated to adjust the length of the support rod 9, thereby improving the practicality of the device. Furthermore, when the lead angle of the worm 7 is less than the equivalent friction angle between the meshing worm wheel 10, it becomes self-locking. This means that the worm wheel 10 cannot drive the worm 7 to rotate, thus improving the stability of the device when it is fixed. It also facilitates the fixed placement of the device. This method solves the technical problem that the unfolding and retracting process of adjusting the outriggers is very troublesome, which easily increases the labor intensity of the operator and makes it inconvenient to operate the device quickly.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
