Description

Technical Field

[0001] This utility model relates to the field of laser ranging device technology, and more specifically, to a portable laser ranging device. Background Technology

[0002] Laser rangefinding uses a laser as a light source to measure distance. A common laser rangefinding device is the laser rangefinder. When working, the laser rangefinder emits a very narrow laser beam towards the target. A photoelectric element receives the laser beam reflected from the target, and a timer measures the time it takes for the laser beam to travel from emission to reception, calculating the distance from the observer to the target. Currently, an auxiliary lanyard is usually attached to the laser rangefinder to facilitate carrying it.

[0003] For example, a portable laser rangefinder disclosed in patent CN220188713U, although it protects each button with a protective device to prevent accidental activation of other buttons when only one button is needed, has a problem in actual use. Because the auxiliary rope is installed at the corner of the laser rangefinder, when the rope is fixed to the user's wrist for carrying, the laser rangefinder swings, making it prone to collisions with the user and damage. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a portable laser rangefinder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable laser rangefinder device includes a laser rangefinder body. One side wall of the laser rangefinder body extends outward to form a mounting part. A mounting groove is provided on the mounting part. A cavity is provided along the length of the opposite side wall of the mounting groove. A connector is provided in the cavity. A strap is provided on the laser rangefinder body. One end of the strap is rotatably connected to the lower side of the laser rangefinder body. The other end of the strap is provided with a fixing member. The fixing member is fixed in the mounting groove to enable the laser rangefinder body to be worn on the arm. The fixing member and the connector cooperate to enable the fixing member to be installed and removed in the mounting groove.

[0007] Furthermore, the connector includes a slider disposed in the cavity by a first spring, the first spring being used to push one end of the slider into the mounting groove, and the extended end of the slider being provided with a first inclined surface; the fixing block is provided with a cavity with openings at both ends, the fixing block being inserted into the mounting groove to drive the first inclined surface to realize the extension and retraction of the slider, so that the slider can be inserted into the cavity to fix the fixing block, and the cavity is provided with a driving component for driving the slider to retract.

[0008] Furthermore, the driving component includes a lifting block disposed within the cavity and capable of being raised and lowered. The side wall opposite to the lifting block is provided with a second inclined surface adapted to the first inclined surface. The lifting block is provided with a mounting post, the upper end of which extends through the side wall of the cavity. A second spring is sleeved on the mounting post located within the cavity. The second spring is used to push the lifting block to move downward. The extended end of the mounting post is provided with a rotating component for driving the lifting block to move upward.

[0009] Furthermore, the rotating component includes a rotating block with a connecting groove. The protruding end of the mounting post extends into the connecting groove, and the protruding end of the mounting post is hinged to the connecting groove via a hinge shaft.

[0010] Furthermore, a buckle groove is provided on the lower side of the laser rangefinder body near the other side wall, and a fixing strip is provided in the buckle groove. One end of the strap passes through the buckle groove and is wrapped around the fixing strip.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0028] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0029] Combination Figures 1-6 As shown, a portable laser rangefinder device in this embodiment includes a laser rangefinder body 100. One side wall of the laser rangefinder body 100 extends outward to form a mounting part 110. A mounting groove 120 is provided on the mounting part 110. A cavity 200 is provided on the opposite side wall of the mounting groove 120 along its length direction. A connector is provided in the cavity 200.

[0030] The laser rangefinder body 100 is provided with a strap 130. One end of the strap 130 is rotatably connected to the lower side of the laser rangefinder body 100. The other end of the strap 130 is provided with a fastener. The fastener is fixed in the mounting groove 120 to enable the laser rangefinder body 100 to be worn on the arm. The fastener and the connector cooperate to enable the fastener to be installed and removed in the mounting groove 120.

[0031] In this embodiment, as Figure 3 As shown, the laser rangefinder body 100 has an existing structure, which includes an outer shell. A mounting part 110 is formed on one side wall of the outer shell. The mounting groove 120 is opened at the middle position of one side wall of the mounting part 110. A buckle groove 320 is opened on the lower side of the outer shell near the other side wall. A fixing strip is provided in the buckle groove 320. One end of the strap 130 passes through the buckle groove 320 and is wrapped around the fixing strip to realize the rotational installation of one end of the strap 130 on the outer shell.

[0032] In practical use, this embodiment involves placing the laser rangefinder body 100 on the operator's arm and sliding the fixing member into the mounting groove 120, allowing the two connecting members to extend into the fixing member. This ensures the fixing member is securely installed within the mounting groove 120, and consequently, the other end of the strap 130 is also secured within the mounting groove 120. This allows the laser rangefinder body 100 to be firmly attached to the operator's arm without swinging, thus effectively preventing the laser rangefinder from being bumped or damaged.

[0033] Combination Figure 3 As shown, in this embodiment, the fixing member includes a fixing block 140. A groove 300 is provided on the lower side of the fixing block 140. An installation strip is provided in the groove 300. The other end of the strap 130 passes through the groove 300 and covers the installation strip, so as to realize the rotational installation of the fixing block 140 at the other end of the strap 130.

[0034] Specifically, the end of the strap 130 is sewn to the side of the strap 130 by stitching to form a closed loop that can be fitted onto the corresponding mounting strip and fixing strip.

[0035] Combination Figures 2-3 As shown, in this embodiment, the connector includes a slider 230 disposed in the chamber 200 by a first spring 220. The first spring 220 is used to push one end of the slider 230 into the mounting groove 120. A first inclined surface 410 is provided on the extended end of the slider 230.

[0036] The fixing block 140 has a cavity with openings at both ends. The fixing block 140 is inserted into the mounting groove 120 to drive the first inclined surface 410 to extend and retract the slider 230, so that the slider 230 can be inserted into the cavity to fix the fixing block 140. The cavity is provided with a drive component for driving the slider 230 to retract.

[0037] Combination Figure 4 As shown, in this embodiment, in order to install the slider 230 in the chamber 200, a limiting groove 210 is provided on the opposite side wall of the chamber 200 along its length direction. The opening of the limiting groove 210 is connected to the mounting groove 120. A limiting block 400 is provided on the opposite side wall of the slider 230, which slides into the corresponding limiting groove 210. When the limiting block 400 slides into the limiting groove 210, a plug is provided at the opening of the limiting groove 210, so that the limiting block 400 can be slidably installed in the corresponding limiting groove 210, thereby realizing the installation of the slider 230 in the chamber 200 and preventing the first spring 220 from pushing the slider 230 out of the chamber 200, that is, realizing the installation of the connector in the chamber 200.

[0038] In actual use, the fixing block 140 is slid into the mounting groove 120 from bottom to top, so that the side wall of the fixing block 140 can abut against the corresponding first inclined surface 410. The fixing block 140 continues to slide upward, so that the side wall of the fixing block 140 can slide and press against the first inclined surface 410, driving the slider 230 to retract into the cavity 200 and compressing the first spring 220. When the opening of the cavity is aligned with the opening of the cavity 200, the first spring 220 drives the slider 230 to extend, so that it automatically inserts into the cavity, thereby preventing the fixing block 140 from sliding up and down in the mounting groove 120, thus achieving the fixed installation of the fixing block 140 in the mounting groove 120.

[0039] The slider 230 is adapted to the cavity so that when the slider 230 enters the cavity, the side wall of the slider 230 can fit against the corresponding side wall of the cavity, thereby preventing the fixing block 140 from shaking and thus allowing the fixing block 140 to be better fixed.

[0040] The driving mechanism allows the two sliders 230 to be pushed out of the cavity, so that the fixing block 140 can be released from the mounting slot 120, and the laser rangefinder body 100 can be released from the arm, allowing the operator to remove the laser rangefinder body 100 for distance measurement.

[0041] Combination Figures 2-6As shown, in this embodiment, the driving component includes a lifting block 270 disposed in the cavity and capable of being raised and lowered. The side wall opposite to the lifting block 270 is provided with a second inclined surface 500 adapted to the first inclined surface 410. The lifting block 270 is provided with a mounting post 250. The upper end of the mounting post 250 extends through the side wall of the cavity. A second spring 240 is sleeved on the mounting post 250 located in the cavity. The second spring 240 is used to push the lifting block 270 to move downward. The extended end of the mounting post 250 is provided with a rotating component for driving the lifting block 270 to move upward.

[0042] In actual use, this embodiment, through the arrangement of the lifting block 270, the second spring 240 and the mounting post 250, enables the second spring 240 to push the lifting block 270 to fit against the bottom wall of the cavity in the initial state. At this time, the slider 230 can extend into the cavity to fix the fixing block 140 and keep the first inclined surface 410 and the corresponding second inclined surface 500 in cooperation. When the extended end of the mounting post 250 is pulled upward, the mounting post 250 can drive the lifting block 270 to drive the second inclined surface 500 to move upward, so that the second inclined surface 500 can slide and squeeze the first inclined surface 410, thereby enabling the second inclined surface 500 to drive the slider 230 to disengage from the cavity, thereby releasing the slider 230 from fixing the fixing block 140, so that the fixing block 140 can be disassembled in the mounting groove 120.

[0043] The rotating component drives the mounting column 250 upward and keeps the lifting block 270 at its highest point. At this point, the second inclined plane 500 drives the slider 230 to disengage from the cavity, thereby releasing the slider 230 from the fixing block 140. This effectively prevents the laser rangefinder body 100 from falling off the operator's arm and causing damage due to excessive force when pulling the mounting column 250 upward.

[0044] Combination Figures 2-6 As shown, in this embodiment, the rotating component includes a rotating block 150, on which a connecting groove is provided. The protruding end of the mounting post 250 extends into the connecting groove, and the protruding end of the mounting post 250 is hinged to the connecting groove via a hinge shaft 260.

[0045] In actual use, one end of the rotating block 150 forms an abutment portion 520, and the other end forms a toggle portion 510. When the rotating block 150 rotates to a horizontal position, the abutment portion 520 does not contact the upper side of the fixed block 140, allowing the second spring 240 to push the lower side of the lifting block 270 against the bottom wall of the cavity, and causing the rotating block 150 to horizontally conform to the upper side of the fixed block 140. At this time, by actuating the toggle portion 510, the rotating block 150 can rotate around the hinge shaft 260. When the abutment part 520 abuts against the upper side wall of the fixing block 140, the rotating block 150 can drive the mounting column 250 to move the lifting block 270 upward and keep it in the highest position, so that the fixing block 140 can always be kept in the released state, which makes it easy for the operator to operate with one hand to remove the laser rangefinder body 100 worn on the arm; when the rotating block 150 is turned to the horizontal by moving the toggle part 510, the lifting block 270 can be reset, so that the fixing part can be reused.

[0046] When wearing the laser rangefinder body 100 on the arm, first, the actuating part 510 is turned to make the rotating part horizontal. Then, the laser rangefinder body 100 is placed against the inside of the arm, and the laser rangefinder body 100 is pressed with the fingers to pre-fix it on the arm. Next, the fixing block 140 is slid into the mounting groove 120 from bottom to top, so that the side wall of the fixing block 140 can abut against the first inclined surface 410. The fixing block 140 is continued to slide upward, so that the side wall of the fixing block 140 can slide and press the first inclined surface 410, so that the first inclined surface 410 can drive the slider 230 to slide into the cavity 200. When the opening of the cavity is aligned with the opening of the cavity 200... At this time, under the action of the first spring 220, the two first springs 220 can push the corresponding slider 230 into the cavity, so that the fixing block 140 can be fixedly installed in the mounting groove 120, that is, the laser rangefinder body 100 can be worn on the arm; when it is necessary to remove the laser rangefinder body 100, by moving the toggle part 510, the abutment part 520 abuts against the upper side wall of the fixing block 140. At this time, the rotating block 150 can drive the mounting column 250 to move the lifting block 270 upward and keep it in the state of moving to the highest point, so that the fixing block 140 can always be kept in the released state, which makes it convenient for the operator to operate with one hand to remove the laser rangefinder body 100 worn on the inside of the arm.

[0047] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
