Description

Technical Field

[0001] This utility model relates to a laser rangefinder, specifically a laser rangefinder that is easy to install. Background Technology

[0002] A laser rangefinder is an electronic instrument that uses a laser beam to accurately measure the distance to a target. Its basic principle is to emit a highly concentrated laser beam towards the target, and then calculate the distance based on the speed of light by detecting the time (or phase difference) it takes for the laser to travel from emission to return to the instrument. Simply put, it's like a "light ruler," using light instead of the measuring tape.

[0003] A typical laser rangefinder consists of the rangefinder body and a stand. During measurement, the rangefinder body can generally be held directly in hand; however, since shaking or movement while holding it directly affects the accuracy of the measurement results, a stand is often used when high-precision measurements are required. The rangefinder body is usually fixedly mounted with a connecting nut; the stand is fixedly mounted with a connecting screw. The connection between the connecting screw and the connecting nut allows the rangefinder body and the stand to be installed.

[0004] Since the elevation of the rangefinder is a crucial reference indicator during measurement (the measurement result typically shows the distance between the measuring point and the object being measured at a certain clearance height), each installation requires precise alignment of the screw with the screw hole, followed by a fixed number of rotations. This ensures proper installation and maintains the correct distance between the rangefinder and the support. This installation method is relatively time-consuming and labor-intensive; furthermore, installation errors are easily introduced during the process (the number of rotations can be easily confused, leading to discrepancies between the measured elevation and the design value). Utility Model Content

[0005] The purpose of this invention is to provide a laser rangefinder that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-install laser rangefinder, including a rangefinder body; It also includes a base; the base is rotatably mounted with equally spaced support legs in the circumferential direction; a connecting frame is rotatably mounted on the upper part of the base; the connecting frame is provided with a slot. It also includes a connector; the connector includes multiple sets of connecting posts rotatably mounted on the rangefinder body; the connecting posts cooperate with the slot; the connector is used to quickly connect the rangefinder body and the connecting frame.

[0007] As described above, the easy-to-install laser rangefinder includes: a connector further comprising a groove group formed on the connecting post; a rotating ring rotatably mounted on the connecting frame, the rotating ring being concentrically arranged with the groove opening; and a protruding post fixedly mounted on the rotating ring, which slidably engages with the groove group.

[0008] The laser rangefinder described above is easy to install: the slot group includes a vertical slot, an inclined slot and a horizontal slot; wherein the two ends of the inclined slot are respectively connected to one end of the vertical slot and one end of the horizontal slot, and the other end of the vertical slot is open.

[0009] As described above, the easy-to-install laser rangefinder has a frustoconical end on the connecting column.

[0010] As described above, the easy-to-install laser rangefinder has a diameter smaller than the width of the slot opening.

[0011] As described above, the easy-to-install laser rangefinder has the following features: a baffle is slidably mounted on the connecting column; a spring is wrapped around the connecting column, with both ends of the spring contacting the baffle and the spring itself, respectively.

[0012] As described above, the easy-to-install laser rangefinder has the following features: a lever is fixedly mounted on the rotating ring; a positioning block and a limiting block that cooperate with the lever are fixedly mounted on the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by connecting the rangefinder body and the base with the connector, a quick connection can be achieved, effectively improving the installation efficiency. Since the length of the connecting post extending into the slot is relatively fixed after the connection is completed, the position of the rangefinder body after installation is relatively fixed, thus effectively avoiding measurement errors caused by improper installation. Furthermore, by installing the rangefinder body by rotation, damage to the internal components of the rangefinder body caused by installation impact can be effectively avoided, thereby protecting the rangefinder body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-6 As one embodiment of the present utility model, the easy-to-install laser rangefinder includes a rangefinder body 1; It also includes a base 2; the base 2 is rotatably mounted with equally spaced support legs 3 in the circumferential direction; the upper part of the base 2 is rotatably mounted with a connecting frame 4; the connecting frame 4 is provided with a slot 401; It also includes a connector; the connector includes multiple sets of connecting posts 5 rotatably mounted on the rangefinder body 1; the connecting posts 5 cooperate with the slot 401; the connector is used to quickly connect the rangefinder body 1 and the connecting frame 4.

[0023] In this embodiment, the rangefinder body 1 has two usage modes. Mode 1: handheld use. By rotating the connecting post 5, the connecting post 5 is made parallel to the rangefinder body 1, and the connecting post 5 is embedded in the rangefinder body 1, which can improve the comfort when holding it.

[0024] Mode 2: Erection and Use. By rotating the support legs 3 to adjust the spacing between each support leg 3, the base 2 is placed stably on the ground. Then, rotate the connecting column 5 so that it is perpendicular to the rangefinder body 1 and the connecting column 5 is exposed outside the rangefinder body 1. Then, align the connecting column 5 with the slot 401 and insert the connecting column 5 into the slot 401. Then, connect the connecting column 5 to the connecting frame 4 through the connector to make the rangefinder body 1 and the connecting frame 4 stably connected.

[0025] By connecting the rangefinder body 1 and the base 2 with the connector, a quick connection can be achieved, which effectively improves the installation efficiency. Since the length of the connecting post 5 extending into the slot 401 is relatively fixed after the connection is completed, the position of the rangefinder body 1 after installation is relatively fixed, thus effectively avoiding measurement errors caused by improper installation.

[0026] As a further embodiment of this utility model, the connector further includes a groove group formed on the connecting post 5; a rotating ring 8 is rotatably mounted on the connecting frame 4, and the rotating ring 8 is concentrically arranged with the groove 401; a protruding post 801 that slides and engages with the groove group is fixedly mounted on the rotating ring 8.

[0027] In this embodiment, during the process of inserting the connecting post 5 into the slot 401, it will engage with the rotating ring 8; and the protruding post 801 will enter the slot assembly.

[0028] Then, rotating the rotating ring 8 causes the protruding column 801 to slide in the groove. The squeezing action of the protruding column 801 on the groove wall causes the connecting column 5 to continue extending into the groove opening 401. Since the rotation angle of the rotating ring 8 is fixed, the sliding distance of the protruding column 801 in the groove is fixed, and the extension distance of the connecting column 5 is also fixed. This makes the position of the rangefinder body 1 relatively fixed after installation, thus effectively avoiding measurement errors caused by improper installation. Furthermore, installing the rangefinder body 1 by rotation effectively avoids damage to the internal components of the rangefinder body 1 caused by installation impact, thereby protecting the rangefinder body 1.

[0029] As a further embodiment of the present invention, the groove group includes a vertical groove 501, an inclined groove 502 and a horizontal groove 503; wherein the two ends of the inclined groove 502 are respectively connected to one end of the vertical groove 501 and one end of the horizontal groove 503, and the other end of the vertical groove 501 is open.

[0030] In this embodiment, during the process of inserting the connecting post 5 into the slot 401, the protruding post 801 will enter the vertical slot 501 from the open end of the vertical slot 501, and under the action of the gravity of the rangefinder body 1, the protruding post 801 will slide in the vertical slot 501 to the connection between the vertical slot 501 and the inclined slot 502.

[0031] When the rotating ring 8 is rotated, the protruding column 801 will first slide in the inclined groove 502 towards the horizontal groove 503. Through the squeezing action of the protruding column 801 on the groove wall of the inclined groove 502, the connecting column 5 can continue to slide inward in the groove 401.

[0032] When the protruding post 801 slides into the transverse groove 503, the squeezing action between the groove wall of the transverse groove 503 and the protruding post 801 can restrict the separation of the connecting post 5 from the groove 401, thereby preventing connection failure after installation and improving the stability of the connection.

[0033] By connecting the rangefinder body 1 and the base 2 with the connector, a quick connection can be achieved, which effectively improves the installation efficiency. Since the length of the connecting post 5 extending into the slot 401 is relatively fixed after the connection is completed, the position of the rangefinder body 1 after installation is relatively fixed, thus effectively avoiding measurement errors caused by improper installation.

[0034] As a further embodiment of this invention, the end of the connecting column 5 is truncated cone-shaped.

[0035] In this embodiment, the end of the connecting post 5 is truncated cone-shaped, which can effectively reduce the difficulty of inserting the connecting post 5 into the slot 401 (the diameter of the slot 401 is slightly larger than the diameter of the connecting post 5, which on the one hand ensures that the connecting post 5 can enter the slot 401, and on the other hand makes the installation gap between the connecting post 5 and the slot 401 relatively small, thereby avoiding the rangefinder body 1 from shaking on the connecting frame 4 after installation; however, the smaller installation gap will increase the difficulty of inserting the connecting post 5 into the slot 401). Even if there is a slight misalignment, it can be automatically corrected, simplifying the alignment process and improving the assembly speed and fault tolerance.

[0036] As a further embodiment of this utility model, the diameter of the protruding post 801 is smaller than the width of the groove 503.

[0037] As a further embodiment of this utility model, a baffle 7 is slidably installed on the connecting post 5; a spring 6 is wrapped around the connecting post 5, and the two ends of the spring 6 respectively abut against the baffle 7 and the spring 6.

[0038] In this embodiment, after the connecting post 5 is inserted into the slot 401, the baffle 7 will first abut against the connecting frame 4. Then, under the gravity of the rangefinder body 1, the connecting post 5 will slide inward a distance in the slot 401. During this process, the protruding post 801 will enter the vertical slot 501 and slide in the vertical slot 501 to the connection end of the vertical slot 501 and the inclined slot 502. The connecting frame 4 will squeeze the baffle 7, causing the baffle 7 to slide on the connecting post 5 towards the rangefinder body 1 and compress the spring 6.

[0039] As the protruding post 801 slides in the inclined groove 502, the connecting post 5 continues to slide inward in the slot 401, causing the baffle 7 to continue sliding towards the rangefinder body 1, further compressing the spring 6. When the protruding post 801 slides into the transverse groove 503, the elastic force of the spring 6 causes the protruding post 801 to abut against the groove wall of the transverse groove 503 away from the rangefinder body 1. The elastic force of the spring 6 is converted into a clamping force that tightly presses the connecting post 5 against the protruding post 801, ensuring that there is no loosening after connection. At the same time, it also provides the reset force required for unlocking.

[0040] Meanwhile, since the width of the groove 503 is greater than the diameter of the protruding post 801, the protruding post 801 can move axially along the connecting post 5 within the groove 503. This avoids problems such as "jamming" or "incomplete locking" caused by machining errors or dimensional interference. If the diameter of the protruding post 801 is greater than or equal to the groove width, it will not be able to slide smoothly into the groove 503, or it will generate huge friction and wear. This design ensures the smoothness of the locking action and the stability of the final locked position; on the other hand, when used in environments with vibration, the spring force of the spring 6 can weaken or offset the influence of vibration on the measurement results, and the groove 503 provides buffer space for the movement of the protruding post 801.

[0041] By connecting the rangefinder body 1 and the base 2 with the connector, a quick connection can be achieved, which effectively improves the installation efficiency. Since the length of the connecting post 5 extending into the slot 401 is relatively fixed after the connection is completed, the position of the rangefinder body 1 after installation is relatively fixed, thus effectively avoiding measurement errors caused by improper installation.

[0042] As a further embodiment of this utility model, a lever 802 is fixedly installed on the rotating ring 8; a positioning block 402 and a limiting block 403 that cooperate with the lever 802 are fixedly installed on the connecting frame 4.

[0043] In this embodiment, in the initial position, the lever 802 abuts against the positioning block 402, fixing the position of the rotating ring 8 (positioning function), thereby fixing the position of the protruding post 801 and allowing it to smoothly enter the vertical groove 501, thus avoiding installation obstruction. Once the protruding post 801 enters the horizontal groove 503, the abutment between the limiting block 403 and the lever 802 indicates to the operator that the rangefinder is properly installed, preventing excessive rotational force from causing the protruding post 801 to bend and deform, thereby improving its service life.

[0044] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
