Description

Technical Field

[0001] This utility model belongs to the field of rangefinder manufacturing technology, and in particular relates to a portable rangefinder. Background Technology

[0002] According to the published patent CN214951278U, a portable rangefinder includes a rangefinder body, a laser unit, a control panel, and a processor. A support frame is located on the upper part of the rangefinder body. The rangefinder projects measurement data via a laser dot matrix generator for easy image storage. However, it still has the following shortcomings:

[0003] After the above equipment is completed, since the measurement work may need to be carried out in different environments and the environmental conditions may be quite complex, such as in field geological exploration, surveyors need to frequently move the measurement position in rugged terrain. If the rangefinder is not quickly installed, it may lead to a decrease in the work efficiency of the staff, which may increase the workload of the staff. Therefore, we provide a portable rangefinder.

Through the holding mechanism and the carrying mechanism, it solves the problem that after the above-mentioned equipment is completed, the measurement work may need to be carried out in different environments and the environmental conditions may be relatively complex. For example, in field geological exploration, the surveyors need to frequently move the measurement position in rugged terrain. If the rangefinder is not quickly installed, it may lead to a decrease in the work efficiency of the staff and thus increase the workload of the staff.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a portable rangefinder, including a base plate, the inner wall of which has a plurality of slots, a second slot, and a clamping mechanism.

[0007] The clamping mechanism includes a base frame, the outer wall of which is slidably connected to the inner wall of a base plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 As shown, this utility model is a portable rangefinder, including a base plate 1, a plurality of slots 101 are provided on the inner wall of the base plate 1, a second slot 102 is provided on the inner wall of the base plate 1, and a clamping mechanism 2 is provided on the inner wall of the base plate 1.

[0031] The clamping mechanism 2 includes a base frame 201. The outer wall of the base frame 201 is slidably connected to the inner wall of the base plate 1. The base plate 1 stabilizes the position of the base frame 201, preventing it from tilting during use and causing damage to the device. Several fixing plates 202 are fixedly connected to the outer wall of the base frame 201. An auxiliary plate 203 is fixedly connected to the outer wall of the fixing plate 202 away from the base plate 1. Several sliding grooves 204 are formed on the inner wall of the auxiliary plate 203. A threaded rod 205 is rotatably connected to the inner wall of the base frame 201. The fixing plates 202 fix the position of the auxiliary plate 203, preventing it from falling off during use and causing the device to lose stable clamping capability. The outer wall of the threaded rod 205 is rotatably connected to the inner wall of the sliding grooves 204. A worm gear is fixedly connected to the outer wall of the threaded rod 205 near the base plate 1. 206. A worm gear 207 is rotatably connected to the inner wall of the base frame 201. The outer wall of the worm gear 207 meshes with the outer wall of the worm wheel 206. A rotating plate 208 is fixedly connected to the outer wall of the threaded rod 205 away from the base plate 1. The base frame 201 enables the threaded rod 205 to rotate stably, preventing the threaded rod 205 from tilting during rotation and causing the device to jam. Several sliding grooves 209 are provided on the inner wall of the rotating plate 208. A sliding rod 210 is slidably connected to the inner wall of the rotating plate 208. The outer wall of the sliding rod 210 is slidably connected to the inner wall of the auxiliary plate 203. A clamping plate 211 is fixedly connected to the outer wall of the sliding rod 210 away from the auxiliary plate 203. The movement of the sliding rod 210 drives the clamping plate 211 to move stably, avoiding the problem that the clamping plate 211 cannot move and the device cannot be used normally.

[0032] A rangefinder 212 is slidably connected to the outer wall of the rotating plate 208 near the clamping plate 211. A threaded barrel 213 is threadedly connected to the outer wall of the threaded rod 205. A portable mechanism 3 is provided on the outer wall of the base plate 1. The portable mechanism 3 includes several rotating shafts 301, the outer walls of which are rotatably connected to the inner wall of the base plate 1. The specific model of the rangefinder 212 is Fluke 404E or 406E, which features speed, accuracy, and durability. Its simple design and easy-to-operate buttons allow for one-handed operation, helping users quickly obtain accurate measurement data and reduce errors. The auxiliary shell 302 is fixedly connected to the outer wall of the rotating shaft 301, and the telescopic rod 309 is fixedly connected to the inner wall of the base frame 201. The outer wall of the telescopic rod 309 is fitted with a spring 310. A locking rod 311 is fixedly connected to the outer wall of the end of the spring 310 away from the clamping plate 211. A pull block 303 is fixedly connected to the outer wall of the auxiliary shell 302 away from the base plate 1. The locking rod 311 can be moved stably by the telescopic rod 309 and the spring 310 to prevent the locking rod 311 from tilting during movement, which would affect the normal use of the device.

[0033] A connecting plate 304 is fixedly connected to the outer wall of the left auxiliary shell 302. A telescopic rod 305 is fixedly connected to the outer wall of the connecting plate 304. A spring 306 is sleeved on the outer wall of the telescopic rod 305. A locking block 307 is fixedly connected to the outer wall of the end of the spring 306 near the auxiliary shell 302. The connecting plate 304 ensures the stable use of the telescopic rod 305, preventing it from falling off during use and thus ensuring the device can be operated in a portable manner. A second connecting plate 308 is fixedly connected to the outer wall of the right auxiliary shell 302. The inner wall of the second connecting plate 308 is slidably connected to the outer wall of the locking block 307. A locking rod 311 is close to the clamping point. An auxiliary shaft 312 is rotatably connected to the inner wall of one end of plate 211. The auxiliary shaft 312 is rotated stably by the locking rod 311 to prevent the auxiliary shaft 312 from tilting during rotation and causing the device to jam. An auxiliary plate 313 is fixedly connected to the outer wall of the auxiliary shaft 312. An auxiliary shaft 314 is fixedly connected to the outer wall of the end of the auxiliary plate 313 away from the auxiliary shaft 312. The outer wall of the auxiliary shaft 314 is rotatably connected to the inner wall of the threaded barrel 213. The movement of the threaded barrel 213 drives the auxiliary shaft 314 to move stably, avoiding the problem that the auxiliary shaft 314 cannot move and the device cannot be fixed in position.

[0034] One specific application of this embodiment is:

[0035] When the operator needs to use the equipment, first place the base frame 201 in the slot 102, then place the rangefinder 212 on the rotating plate 208, and then rotate the worm gear 207. The rotation of the worm gear 207 drives the worm wheel 206 to rotate, which in turn drives the threaded rod 205 to rotate. The threaded rod 205 then drives the rotating plate 208 to rotate. The rotation of the rotating plate 208 causes the sliding rods 210 at both ends to slide in the sliding groove 209. At the same time, the sliding rods 210 move within the sliding groove 204. The sliding rods 210 at both ends move in opposite directions, driving the clamping plate 211 to move. The movement of the clamping plate 211 clamps the rangefinder 212. Simultaneously, the rotation of the threaded rod 205 drives the threaded barrel 213 to move. The movement of the threaded barrel 213 causes the auxiliary shafts 314 at both ends to move, and these auxiliary shafts 314 rotate inside the threaded barrel 213. The auxiliary shafts 314 drive the auxiliary plate 313 to move, and the movement of the auxiliary plate 313 drives the auxiliary shaft 312 to move. The movement of the auxiliary shaft 312 causes the locking rod 311 to rotate inside the locking rod 311, which in turn stretches the spring 310 and moves the locking rod 311 into the insertion slot 101. The locking rod 311 stabilizes the position of the base frame 201, the fixing plate 202, and the device. When the device needs to be carried, the locking block 307 is pulled, causing it to press against the telescopic rod 305 and the spring 306. The spring 306 causes the locking block 307 to retract, and then the rotating shafts 301 at both ends rotate. Shaft 301 drives auxiliary housing 302 to rotate until both auxiliary housings 302 rotate to the position of mutual contact. Then, release the locking block 307, and use spring 306 to return the locking block 307 to its initial position and insert it into the connecting plate 2 308. The locking block 307 and the connecting plate 2 308 fix the position of the auxiliary housing 302. At this time, simply pull the pull block 303 to realize the portable function of the device. When the rangefinder 212 needs to be used, pull the locking block 307 again, and then reverse the above steps.
