Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, and specifically relates to a laser rangefinder. Background Technology

[0002] Laser rangefinders, as a commonly used distance measurement tool, are widely used in construction, engineering, and military fields due to their speed and accuracy. However, traditional laser rangefinders have a significant limitation: the user must stand at one of the points to be measured. This method becomes impractical when the point is in a difficult-to-reach location (such as at high altitudes, dangerous areas, or confined spaces).

[0003] To address the aforementioned issues, Chinese invention patent application number 201811332332.4 discloses a laser rangefinder, which includes a housing, a first ranging module, a second ranging module, and a rotating mechanism. The rotating mechanism divides the housing into a first part and a second part, and both the first part and the second part rotate around the rotating mechanism. The first ranging module is disposed within the first part, and the second ranging module is disposed within the second part. An angle sensor is disposed within the rotating mechanism, and the angle sensor is used to measure the angle between the first part and the second part with the rotating mechanism as the vertex.

[0004] While the above solutions have expanded the application range of laser rangefinders to some extent, they still have at least the following shortcomings:

[0005] 1. Angle Adjustment Issue: The angle between the two ranging modules needs to be precisely adjusted to ensure the accuracy of the measurement results. However, manually adjusting the angle is not only complicated to operate, but also prone to introducing human error.

[0006] 2. Relative rotation problem: During use, the two ranging modules may rotate relative to each other, causing the measurement reference to change, which will affect the final distance calculation result;

[0007] 3. Inconvenient to carry: The device integrates a rotating mechanism, multiple sensors and a display screen, which inevitably increases the size and weight of the device, thus affecting its portability. Utility Model Content

[0008] The purpose of this invention is to provide a laser rangefinder to partially alleviate or solve the above-mentioned shortcomings and improve the stability of the laser rangefinder.

[0009] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0010] A laser rangefinder includes a first body, a second body, and a locking mechanism; the first body includes a first housing and a first ranging module disposed inside the first housing; the second body includes a second housing and a second ranging module disposed inside the second housing.

[0011] The first end of the second housing is provided with a receiving cavity, and the first end of the first housing is provided with a guide groove penetrating the first housing, and the first end of the first housing is disposed in the receiving cavity;

[0012] The locking mechanism includes a first locking member, a second locking member, and a reset member. The first locking member is fixedly disposed on the top of the receiving cavity. The second locking member is located in the guide groove and corresponds to the first locking member. The first end of the reset member is connected to the bottom of the receiving cavity, and the second end of the reset member is connected to the second locking member.

[0013] When the second locking member is pressed, it separates from the first locking member, allowing the first housing to rotate around the first end of the second housing. When the external force on the second locking member is removed, the reset member resets, causing the second locking member to reset as well. The second locking member engages with the first locking member to achieve locking, thereby fixing the second housing and the first housing.

[0014] As an improvement, the length of the first housing is less than or equal to the length of the receiving cavity, so that the first housing can be completely housed inside the receiving cavity.

[0015] As an improvement, the second housing is divided into a receiving area and a functional area from its first end to its second end. The receiving cavity is disposed in the receiving area, and the second ranging module is disposed in the functional area. The receiving area includes an upper housing and a lower housing that are parallel to each other. The upper housing, the lower housing, and the sidewalls of the functional area enclose an open space, allowing the first housing to rotate within the open space.

[0016] As an improvement, the laser rangefinder also includes a battery and a control panel, which are located in the functional area and are respectively connected to the first ranging module and the second ranging module.

[0017] As an improvement, the laser rangefinder also includes a battery and a control panel, which are disposed within the second housing and are respectively connected to the first ranging module and the second ranging module.

[0018] As an improvement, a limiting member is provided on one side of the cavity along its length, so that the angle of rotation of the first housing relative to the second housing is less than 360°.

[0019] As an improvement, the limiting member is disposed at the first end of the second housing, and the length of the limiting member is less than the length of the receiving cavity, so that an operating hole is formed between the limiting member and the second housing.

[0020] As an improvement, a pressing hole is provided at the top of the receiving cavity, a through hole is provided on the first locking member, and a receiving groove is provided at the bottom of the receiving cavity; the pressing hole, the through hole, the guide groove and the receiving groove are connected in sequence.

[0021] At least a portion of the second locking member extends sequentially from the guide groove and the through hole and is located within the pressing hole, while at least a portion of the reset member is located within the receiving groove.

[0022] As an improvement, when no external force is applied to the second locking member, at least a portion of the second locking member extends out of the pressing hole and is located outside the receiving cavity.

[0023] As an improvement, the second locking member includes a locking portion that cooperates with the first locking member, and a pressing portion that cooperates with the pressing hole and the through hole, at least a portion of the pressing portion extending out of the pressing hole and located outside the receiving cavity.

[0024] The principle and beneficial technical effects of this utility model are as follows:

[0025] When using a laser rangefinder for distance measurement, it is necessary to maintain the stability of the rangefinder. Current technology usually uses a bracket (such as a tripod) to fix the laser rangefinder. However, this device is bulky, and most households do not have a bracket, so not only is measurement cumbersome, but accuracy is also difficult to guarantee. For example, when home users use a handheld rangefinder for distance measurement, shaking or positional shifts are inevitable. This usually causes the angle between the two ranging modules to change, and then the user needs to manually readjust the angle between the two ranging modules, which is tedious and the measurement accuracy is difficult to guarantee.

[0026] To address the miniaturization needs of home rangefinders, this application provides a rangefinder solution for a limited miniature rangefinder by restricting the rotation angle of the two rangefinder modules and achieving relative rotation and rapid locking between them through a push-type locking mechanism.

[0027] Firstly, for handheld miniaturized rangefinders, ensuring ease of use and stability is crucial. In this application, the first and second housings employ a press-type locking mechanism for quick locking or unlocking. When adjusting the angle of the first and second housings, pressing the second locking element allows for relative rotation between them. In other words, the user can adjust the angle by pressing the second locking element with one hand and pushing the first housing with the other. When the desired angle is reached, releasing the second locking element allows it to quickly spring back to its original position, thus achieving rapid locking between the two housings.

[0028] Furthermore, the first and second housings in this application adopt an "embedded" installation method, which allows the first housing to be completely embedded into the second housing to form a whole, improving the space utilization of the rangefinder, reducing the size of the rangefinder, and making it easier to store; at the same time, with the help of the limiting component, the first housing can only rotate within a limited range, which can cover all measurement scenarios, and will not cause problems such as difficulty in angle adjustment or excessive wear of parts due to excessive rotation.

[0044] Example 1

[0045] This embodiment is basically as follows: Figures 1-10 As shown:

[0046] See Figure 1 This utility model provides a laser rangefinder, including a first main body, a second main body, and a locking mechanism 3; the first main body includes a first housing 1 and a first ranging module disposed inside the first housing 1; the second main body includes a second housing 2 and a second ranging module disposed inside the second housing 2; the first end of the second housing 2 is provided with a receiving cavity 201, the first end of the first housing 1 is provided with a guide groove penetrating the first housing 1, and the first end of the first housing 1 is disposed inside the receiving cavity 201.

[0047] Here, the first end of the first housing and the first end of the second housing refer to the ends where they are connected. In other words, the first end of the first housing is embedded in the receiving cavity and can rotate relative to the second housing.

[0048] See Figure 7 The locking mechanism includes a first locking member 301, a second locking member 302, and a reset member 303. The first locking member 301 is fixedly disposed on the top of the receiving cavity. The second locking member 302 is located in the guide groove 101 and corresponds to the first locking member 301. The first end of the reset member 303 is connected to the bottom of the receiving cavity 201, and the second end of the reset member 303 is connected to the second locking member 302.

[0049] In some embodiments, the first end of the reset member 303 abuts against the bottom of the receiving cavity 201, and the second end of the reset member 303 abuts against the bottom of the second locking member 302.

[0050] When the second locking member 302 is pressed, causing it to separate from the first locking member, the first housing can rotate around its first end. When the external force on the second locking member is removed, the reset member resets, causing the second locking member to reset as well. The second locking member then engages with the first locking member to lock, thereby fixing the second housing and the first housing. See details... Figure 5 and Figure 6 The diagram shows cross-sectional views of the locking mechanism in both locked and unlocked states. In its natural state (i.e., without external force acting on the locking mechanism), the first and second housings are locked and cannot rotate relative to each other. When the user presses the second locking member, the second locking member disengages from the first locking member, allowing the first housing to rotate relative to the second housing, thereby achieving angle adjustment between them and enabling distance measurement in different scenarios.

[0051] In some embodiments, see Figure 7 The top of the receiving cavity is provided with a pressing hole 203, the first locking member 301 is provided with a through hole 3011, and the bottom of the receiving cavity is provided with a receiving groove 204; the pressing hole 203, the through hole 3011, the guide groove 101 and the receiving groove 204 are connected in sequence; at least a portion of the second locking member 302 extends out of the guide groove and is located in the pressing hole 203, and at least a portion of the reset member 303 is located in the receiving groove 204.

[0052] In some embodiments, when no external force is applied to the second locking member, at least a portion of the second locking member extends out of the pressing hole and is located outside the receiving cavity. For example, the overall height of the second locking member and the reset member is greater than the total height of the guide groove, the pressing hole, the through hole, and the receiving groove.

[0053] In some embodiments, the deformation height of the reset member (i.e., the difference between the height of the reset member when no external force is applied and its minimum height when compressed) is less than or equal to the height of the portion of the second locking member extending out of the pressing hole and located outside the receiving cavity; so that no matter how the user presses the second locking member, a portion of the second locking member is always locked in the pressing hole and the through hole, thereby preventing the first housing from separating from the second housing.

[0054] In some embodiments, see Figure 10The second locking member 302 includes a locking portion 3022 that cooperates with the first locking member 301, and a pressing portion 3021 that cooperates with the pressing hole and the through hole. The locking portion 3022 and the pressing portion 3021 are arranged sequentially from top to bottom, that is, the locking portion 3022 is located near the bottom of the receiving cavity, and the pressing portion 3021 is located near the top of the receiving cavity. The reset member is connected to the locking portion. In some specific embodiments, the diameter of the pressing portion is smaller than the diameter of the locking portion, and the diameter of the locking portion is larger than the diameter of the through hole; that is, the locking portion is always located below the first locking member, while the pressing portion can extend through the through hole of the first locking member to the outside of the receiving cavity and is located on the upper surface of the laser rangefinder for easy pressing by the user.

[0055] In some embodiments, the first locking member and the second locking member are one of an end face ratchet or an end face gear, that is, the sides of the first locking member and the second locking member (the locking part) that are in contact are respectively provided with locking teeth, and the two can be engaged by locking teeth to prevent relative rotation.

[0056] In some embodiments, the reset element is a spring.

[0057] In some embodiments, the length of the first housing is less than or equal to the length of the receiving cavity, so that the first housing can be completely housed inside the receiving cavity. This solution employs an embedded design, which can effectively reduce the size of the device and facilitate storage.

[0058] In some embodiments, see Figure 3 The second housing 2 is divided into a receiving area 21 and a functional area 22 from its first end to its second end. The receiving cavity is disposed in the receiving area 21, and the second ranging module is disposed in the functional area 22; see also Figure 10 The accommodating area includes an upper shell 211 and a lower shell 212 that are parallel to each other. The upper shell 211, the lower shell 212 and the sidewalls of the functional area enclose the accommodating cavity, which has three open sidewalls. That is, the upper shell 211, the lower shell 212 and the sidewalls of the functional area enclose an open space, allowing the first ranging module to rotate within the open space. The first shell can enter or leave the accommodating cavity through the openings and form a certain angle with the second shell.

[0059] In some embodiments, see Figure 7The laser rangefinder also includes a battery 6 and a control panel 7, which are disposed within the second housing. The battery 6 and control panel 7 are connected to the first ranging module 4 and the second ranging module 5 respectively via wires. The battery provides power to both the first and second ranging modules, and the control panel collects signals from both modules.

[0060] In some specific embodiments, both the battery 6 and the control panel 7 are located in the functional area, and the battery 6 and the control panel 7 are respectively connected to the first ranging module 4 and the second ranging module 8 via wires. By partitioning the components, the various parts of the second main body are concentrated in the functional area, and a separate storage space is provided for the first main body. This ensures that the first and second main bodies operate independently without interference, while simultaneously allowing the first main body to be stored in the storage cavity when not in use. The distribution of parts is more rational, effectively reducing the size of the device.

[0061] In some embodiments, a limiting member is provided on one side of the length direction of the receiving cavity (i.e., the length extension direction of the second housing) so that the angle of rotation of the first housing relative to the second housing is less than 360°.

[0062] This solution limits the rotation angle of the first housing, ensuring that the rotation angle basically covers the measurement requirements without excessive rotation that could lead to excessive wear on the laser rangefinder (also referred to as the device) or wire breakage due to unrestricted rotation. Specifically, the first housing can rotate relative to the second housing at any angle within 360°, and can only rotate one full circle. That is, the angle between the first and second housings is 0°-180°. In actual measurement, the maximum angle between the user's location and the two measurement points is 180°. Thus, measurement can be achieved regardless of the location of the two measurement points.

[0063] In some embodiments, see Figure 2 The limiting member 202 is disposed at the first end of the second housing 2, and the length of the limiting member 202 is less than the length of the receiving cavity, so that an operating hole 205 is formed between the limiting member 202 and the second housing 2. As mentioned above, when the laser rangefinder is in the storage state, the first housing is completely embedded in the receiving cavity. This solution provides an operating hole on one side of the limiting member. During use, for example, the user holds the device with their left hand and presses the second locking member with their left thumb, while simultaneously inserting their right fingers into the operating hole to push the first housing out from the opposite side of the limiting member. The user can then pinch any part of the first housing and rotate it.

[0064] In some embodiments, the first ends of both the first housing and the second housing are arc-shaped to facilitate the user's grip and operation of the first end of the laser rangefinder.

[0065] In summary, this application addresses the miniaturization needs of home rangefinders by limiting the rotation angle of the two rangefinder modules and using a push-type locking mechanism to achieve relative rotation and rapid locking between them, thus providing a comprehensive and restrictive rangefinder solution.

[0066] First, the first housing and the second housing in this application adopt a press-type locking mechanism for quick locking or unlocking. When adjusting the angle of the first housing and the second housing, pressing the second locking member can realize the relative rotation of the two; when rotating to the required angle, releasing the second locking member can realize the quick locking of the two.

[0067] Furthermore, the first and second housings in this application adopt an "embedded" installation method, which allows the first housing to be completely embedded into the second housing to form a whole, improving the space utilization of the rangefinder, reducing the size of the rangefinder, and facilitating storage; at the same time, with the help of the limiting component, the first housing can only rotate within a limited range (i.e., within 360°). In other words, the first housing can only rotate one revolution relative to the second housing at most. Therefore, this device can cover all measurement scenarios without causing problems such as difficulty in angle adjustment or excessive wear of parts due to excessive rotation.

[0068] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0069] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
