Technical Field

[0001] The utility model relates to the technical field of distance measuring equipment, in particular to a building distance measuring device. Background Art

[0002] During the decoration process of building interior, it is necessary to measure the distance indoors, and some distance meters are usually used to perform such distance measurement work.

[0003] The prior art discloses a patent with the announcement number CN217110882U, and the patent name is a portable architectural decoration distance measuring device, which specifically discloses a technical solution including a mobile seat, a universal wheel, a base, a screw, a pad, a positioning groove, a rotating shaft, a rangefinder body, a support rod and a horizontal calibrator. The above solution rotates the corresponding screw, and the screw drives the pad to slide by a thread, so as to facilitate the adjustment of the angle between the base and the rangefinder body and the mobile seat, and to facilitate the leveling of the horizontal calibrator, so that the circular level bubble is located in the middle of the horizontal calibrator, so that the rangefinder body is in a horizontal state, which is convenient for using the rangefinder body for distance measurement, has a wide range of applications, and is easy to operate. In addition, by rotating the rotating shaft, it is convenient to adjust the angle of the rangefinder body, and to facilitate comprehensive distance measurement of the building.

[0004] However, in actual applications, the above solution requires multiple adjustments to the angle between the rangefinder and the wall due to the need to measure the distances to multiple walls. In most angle adjustment processes, the user can only rely on the naked eye and experience to determine whether the rangefinder and the wall are perpendicular, which invisibly generates a lot of data errors.

[0005] Therefore, a building distance measuring device is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of this embodiment, the terms "upper", "lower", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The utility model is further described below in conjunction with embodiments.

[0039] Embodiment: Currently in the construction field, most of the distance measurement equipment used is a phase laser rangefinder. Depending on the actual usage scenario, a handheld or tripod-assisted distance measurement can be used indoors. The principle is to emit a very short light pulse and measure the time from the emission to the reflection of the light pulse by the object, and calculate the distance to the object by measuring the time interval.

[0040] In actual use, since it is necessary to measure the distances between different walls and rooms, the angle between the rangefinder (the surface that emits light pulses) and the object to be measured is constantly adjusted. In the prior art, workers either hold the rangefinder for measurement, or mostly use visual inspection to determine whether the rangefinder and the object to be measured are in a vertical state. However, a slight angle will cause a deviation in the measurement result. Placing the tape measure directly on the ground for calibration will also have the risk of obstacles hindering the calibration accuracy (for example, there are obstacles at the measured point).

[0041] Currently, there are some distance measuring devices that can electrically adjust the angle, but these devices are relatively expensive, increasing the cost and carrying burden of the workers, and are not suitable for all construction scenarios.

[0042] The utility model aims to construct a building distance measuring device, which can quickly and conveniently adjust the angle and also makes the angle adjustment more accurate.

[0043] For details, please refer to the attached Figure 1-7 The present solution specifically includes two parts, namely, a rangefinder 1 and a support frame 2. A distance sensor 11 and a power supply module are arranged inside the rangefinder 1. The power supply module includes a plurality of batteries, which are used to supply power to the distance sensor 11 in the present case.

[0044] The support frame 2 is detachably mounted on the bottom of the rangefinder 1 , and includes a fixing platform 21 and a plug sleeve 22 rotatably mounted on the upper end of the fixing platform 21 .

[0045] In this case, three supporting legs are hinged at the bottom of the fixed platform 21, and the cross-section is an I-shaped structure. A scale is opened at the upper end of the fixed platform 21, and the scales are distributed in a circle. In this case, twelve scales are marked, and the angle between adjacent scales is 30°. When in use, after measuring one of the walls, the rangefinder 1 can be rotated three scales on the support frame 2 based on the current position, so that the adjacent wall can be measured.

[0046] Specifically, in the present case, a circular ring 23 parallel to the upper end surface of the fixed platform 21 is provided at the side end of the sleeve 22, and the diameter of the circular ring 23 is larger than the diameter of the cavity in the middle of the fixed platform 23. At the same time, a pressing sleeve 221 that can elastically move up and down is coaxially sleeved on the outer side of the sleeve 22. The pressing sleeve 221 includes three parts from top to bottom, namely a first limiting portion 223, a connecting portion 224 and a second limiting portion 225. The first limiting portion 223 is arranged in parallel at the upper end of the circular ring 23, the connecting portion 224 includes three connecting blocks that vertically penetrate the upper end of the circular ring 23 and extend toward the inside of the fixed platform 21, and the second limiting portion 225 is vertically installed at the bottom end of the connecting portion 224.

[0047] A pointer 232 is disposed at the side end of the ring 23 , and the pointer 232 is parallel to the upper end surface of the fixing platform 23 .

[0048] The pressing sleeve 221 can be guided and slid on the insert sleeve 22, and the bottom end of the pressing sleeve 221 extends into the interior of the fixed platform 21. At the same time, a plurality of protrusions 222 are distributed circumferentially on the bottom end of the pressing sleeve 221. The fixed platform 21 is provided with a card slot 211 that matches the plurality of protrusions 222 one by one. In this case, the protrusion 222 is arranged at the upper end of the second limiting portion 225, and the corresponding card slot 211 is parallel to the second limiting portion 225.

[0049] It is worth noting that in this case, there are twelve protrusions 222 and twelve slots 211 respectively, corresponding to the number of scales.

[0050] In the present case, the interior of the insert sleeve 22 is hollow, and a guide rail 24 and a guide groove are provided at its inner and outer ends respectively. The inner end of the pressing sleeve 221 is provided with a slide groove matched with the guide rail 24. The bottom end of the rangefinder 1 slides in the insert sleeve 22 through the guide rod 12 that can match with the guide groove. When the pressing sleeve 221 rotates, the insert sleeve 22 will rotate synchronously, and the limit fit between the guide rod 12 and the guide groove will drive the insert sleeve 22 to rotate synchronously, thereby achieving the purpose of rotating the rangefinder 1. Therefore, it is only necessary to control the rotation or locking of the pressing sleeve 221d to achieve the free or locked state of the rangefinder 1.

[0051] It is worth noting that a rotating shaft 212 is provided in the middle of the fixed platform 21, and a track matching the guide groove is opened at the outer end of the rotating shaft 212, so that the plug-in sleeve 22 in this case is fixed to the rotating shaft 212 by a snap-fitting manner, so that the rangefinder 1 can be removed from the entire device and can be used handheld, and the usage method can be adjusted according to the actual usage scenario, which is more flexible.

[0052] Specifically, an elastic member is provided between the first limiting portion 223 and the circular ring 23. When the first limiting portion 223 is pressed downward, the elastic member accumulates a certain amount of elastic potential energy, and at this time, the pressing sleeve 221 is released from the lock between the fixing platform 21, that is, the protrusion 222 is disengaged from the slot 211. At this time, rotating the pressing sleeve 221 can drive the inserting sleeve 22 to rotate synchronously.

[0053] The elastic member includes a return spring 231 arranged between the first limit portion 223 and the ring 23, and the return spring 231 respectively contacts the lower end surface of the first limit portion 223 and the upper end surface of the ring 23. The elastic structure specifically used in the elastic member is not limited here, and can be replaced by an elastic paddle, a butterfly spring, etc., which is a well-known technology and will not be elaborated on here.

[0054] The guide rail 24 in this case includes a first rail 241 and a second rail 242 spaced apart from each other. The bottom plane of the first rail 241 is higher than the upper end surface of the return spring 231. When the pressing sleeve 221 is not subjected to downward pressing force, the return spring 231 abutting against one side of the pressing sleeve 221 is in a relaxed state. At this time, the pressing sleeve 221 is engaged with the first rail 241. Since the protrusion 222 provided at the bottom of the pressing sleeve 221 is engaged with the slot 211 provided in the fixing platform 21, the pressing sleeve 221 is in a state where it cannot rotate. Since the first rail 241 is also in an engaged state with the pressing sleeve 221, the entire pressing sleeve 221 and the inserting sleeve 22 are in a locked state and cannot rotate.

[0055] When the pressing sleeve 221 is pressed, the pressing sleeve 221 is disengaged from the first rail 241 and is stuck on the second rail 242. At this time, the protrusion 222 and the slot 211 are correspondingly disengaged. At this time, the pressing sleeve 221 can drive the plug sleeve 22 to rotate. When the expected rotation angle is reached, the pressing sleeve 221 is released, and the return spring 231 at the bottom of the pressing sleeve 221 pops out. The protrusion 222 at the bottom of the pressing sleeve 221 is re-engaged and fixed with the slot 211. At this time, the pressing sleeve 221 and the first rail 241 are in the engaged state again, locking the free rotation of the plug sleeve 22, thereby preventing the rangefinder 1 from rotating due to external factors.

[0056] In this case, the rangefinder 1 can also be adjusted to a certain height.

[0057] Specifically, a support rod 226 is provided in the sleeve 22, and a cavity penetrating the upper and lower end surfaces of the rotating shaft 212 is opened inside the rotating shaft 212, and the upper and lower ends of the support rod 226 pass through the top and bottom of the cavity and extend out, and in this case, the distance between the upper end surface of the support rod 226 and the bottom end of the guide rod 12 is adjustable.

[0058] More specifically, a rotatable knob 213 is provided at the bottom end of the fixed platform 21, and the knob 213 is sleeved on the support rod 226 and is threadedly matched with the support rod 226. When it is necessary to adjust the height of the rangefinder 1, the support rod 226 can be raised to different heights by rotating the knob 213, thereby pushing the guide rod 12 to rise synchronously, thereby achieving the purpose of adjusting the height of the rangefinder 1.

[0059] In practice, a level sensor may be provided on the fixed platform 21 to determine whether the entire device is in a level state to avoid data errors. This is a prior art and will not be described in detail herein and is not shown in the figures.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
