[0001] The utility model relates to the technical field of rangefinders, in particular to a rangefinder with a protective structure. Background Art

[0002] A distance meter is a tool for measuring length or distance. It can also be combined with an angle measuring device or module to measure parameters such as angles and areas. There are many types of distance meters, the most common of which are handheld distance meters.

[0003] For example, the patent document with publication number CN220120991U discloses a rangefinder, which includes a housing, a liquid crystal display, a lanyard mounting port and a button on the surface of the housing, and a ranging laser module and a marking module on the side wall of the housing. The rangefinder has more diverse functions through the design of the ranging laser module and the marking module capable of emitting horizontal lines, vertical lines and cross lines.

[0004] During the use of the above-mentioned device, due to the small size of the device as a whole, the operator needs to hold the device shell to operate it. However, in actual operation, since the device does not have a protective structure, during operation, if the operator's hand slips and fails to hold it firmly, the rangefinder can easily be damaged by collision. For this reason, we propose a rangefinder with a protective structure. Utility Model Content

[0023] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, a rangefinder with a protective structure includes a rangefinder body 1 and a strap 4. A back plate 2 is bonded to the middle of the rear end of the rangefinder body 1, and a rotatable component 3 is provided at the rear end of the back plate 2. The strap 4 is fixed to the outer ends of the rotatable component 3, and Velcro is sewn on the surface of the strap 4. When the rangefinder body 1 is in use, the operator can use the strap 4 to fix the rangefinder body 1 above the palm, thereby enhancing the connection between the rangefinder body 1 and the palm, avoiding the rangefinder body 1 from falling due to hand slippage, thereby achieving the purpose of protecting the rangefinder body 1. At the same time, the strap 4 is composed of a high-elastic elastic band and a relatively hard denim fabric. Therefore, when the two straps 4 are wrapped around the outside of the palm, the position of the strap 4 can be adjusted according to the size of the palm. The rotatable assembly 3 includes a post 301, a rubber inner pad 302, and a sleeve 303. The rubber inner pad 302 is provided on the outer side of the rear end of the post 301. The post 301 is integrally connected to the back plate 2. The sleeve 303 is bonded to the outer side of the rubber inner pad 302. The cross-section of the sleeve 303 is circular when viewed from the front. The strap 4 is symmetrical about the vertical centerline of the sleeve 303. The post 301 can rotate inside the rubber inner pad 302. At the same time, the rubber inner pad 302 greatly increases the friction between the post 301 and the sleeve 303, preventing the rangefinder body 1 connected to the back plate 2 from rotating when the post 301 is used to rotate to any position without the operator touching the rangefinder body 1, thereby facilitating the use of the rangefinder body 1.

[0024] like Figure 1 、 Figure 2 and Figure 5As shown, a mini level bubble 5 is fixedly installed on the inner side of the front end of the rangefinder body 1, and there are two mini level bubbles 5. Side blocks 6 are bonded to the lower left and right ends of the rangefinder body 1, and the interior of the side block 6 is hollow. A through-hole 9 is opened inside the upper side of the side block 6 away from the vertical center line of the rangefinder body 1, and there are two through-holes 9. An auxiliary support 8 is provided on the inner side of the side block 6, and a plug 7 is passed through the upper interior of the auxiliary support 8. The bottom of the auxiliary support 8 is threadedly connected to a hard support pad 10, and the bottom end of the hard support pad 10 is connected to a suction cup, and the cross-section of the hard support pad 10 is circular when viewed from above. When the rangefinder body 1 needs to be used for vertical measurement, the operator can directly place the rangefinder body 1 on the desktop, and then use the adsorption between the suction cup and the desktop to fix the rangefinder body 1 above the desktop, thereby facilitating the use of the rangefinder body 1 and allowing the rangefinder body 1 to measure stably.

[0025] In summary, when using the rangefinder with a protective structure, first Figure 1 、 Figure 3 and Figure 4 As shown, when the rangefinder body 1 needs to be used handheld, the operator places the rangefinder body 1 above the palm, and then holds the ends of the straps 4 at both ends respectively, and wraps the straps 4 around the outside of the palm. Because the straps 4 are mainly composed of high-elastic elastic bands and hard denim, the operator can use the high-elastic elastic bands to adjust the length of the straps 4 during the pulling process, making the straps 4 more flexible during use. During the wrapping process of the straps 4, the front end of the right strap 4 is sewn with a Velcro male surface, and the rear end of the left strap 4 is sewn with a Velcro female surface. Therefore, after the straps 4 are wrapped in the appropriate position, it is only necessary to use the Velcro male surface and the Velcro female surface when wrapped around the outside of the palm. The adhesive properties of the mother-to-be surfaces can be adhered to each other, so that the outer side of the strap 4 can be fixed, thereby enhancing the connection between the rangefinder body 1 and the palm. During handheld measurement of the rangefinder body 1, the operator only needs to hold the outer side of the rangefinder body 1 and rotate it with a little force, so that the embedded column 301 can rotate on the inner side of the rubber inner pad 302. After the rangefinder body 1 is adjusted to a suitable position, the rubber inner pad 302 can increase the friction between the embedded column 301 and the sleeve 303, thereby preventing the rangefinder body 1 from rotating when the operator does not touch the rangefinder body 1, thereby facilitating the use of the rangefinder body 1. Figure 2 and Figure 5As shown, when the rangefinder body 1 needs to be briefly vertically measured, the operator first holds the rangefinder body 1, then places the rangefinder body 1 on the table, and then uses the suction between the suction cup at the bottom of the hard support pad 10 and the table to fix the rangefinder body 1 on the table, so that the rangefinder body 1 can be stably measured. Because the hard support pad 10 and the auxiliary support 8 are threadedly connected, when the rangefinder body 1 does not need to be placed vertically, the operator can remove the hard support pad 10, and then hold the plug 7 and rotate it clockwise at a certain angle to lock the plug 7. By rotating it out from the inner side of the side block 6 and the auxiliary support 8, and then grasping the bottom of the auxiliary support 8 and gently pushing it upward, the hole opened in the side of the auxiliary support 8 is aligned with the through hole 9, and then the plug 7 is inserted into the overlapping hole, so that the auxiliary support 8 stored in the inner side of the side block 6 can be auxiliary fixed. When the rangefinder body 1 is in use, if the strap 4 needs to be removed, it is only necessary to grasp the outer rear end of the sleeve 303 and pull it backward with a little force. After the sleeve 303 is separated from the embedded column 301, the strap 4 connected to the sleeve 303 can be removed, thereby facilitating the use of the rangefinder body 1.
