[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model aims to provide a rangefinder with a depth measurement function to solve the problems existing in the prior art. A depth gauge is added to the existing rangefinder body, so that it can be used for close-range measurement, and the overall volume is small and convenient to carry.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-Figure 6 As shown, the utility model provides a rangefinder with a depth measurement function, including a rangefinder body 1, and the rangefinder body 1 can be a common handheld rangefinder on the market. A guide groove 4 is provided on one side of the rangefinder body 1, and the guide groove 4 can be set on the left or right side of the rangefinder body 1, and can be set according to the user's dominant hand. A depth gauge 6 is slidably connected in the guide groove 4, and the depth gauge 6 is a common ruler structure, and a scale is provided on the depth gauge 6. A push button 3 is also fixedly connected to the depth gauge 6, and the middle part of the push button 3 is slidably connected to the notch of the guide groove 4, and a part of the push button 3 is located in the guide groove 4, which is used for fixed connection with the depth gauge 6; the other part of the push button 3 is located outside the guide groove 4, so that the user can push the push button 3, and the cross-sectional size of the part located outside the guide groove 4 is larger than the cross-sectional size located inside the guide groove 4, so that the push button 3 can be prevented from moving inside the guide groove 4. The upper end of the guide groove 4 is a blind end structure, and the lower end of the guide groove 4 is an open structure, and the depth gauge 6 can extend from the lower end of the guide groove 4.

[0027] In actual use, when long-distance measurement is required, such as measuring straight-line distance, area, and volume during home decoration, for elevation, positioning, and acceptance in engineering, and for calculating earthwork, material area, and volume in building materials, etc., only the distance measuring module 9 inherent in the measuring instrument body is required. If short-distance measurement is required, such as the depth of aluminum alloy grooves, the depth of light strip grooves, the depth of wiring grooves, the depth of punching holes, the depth of woodworking grooves, the depth of fixed spacing, etc., the push button 3 can be pushed at this time, and the push button 3 drives the depth gauge 6 to move downward and extend out of the guide groove 4, and the depth gauge 6 can be used for short-distance measurement.

[0028] In this embodiment, if Figure 2 As shown, a retaining edge 5 is provided on both sides of the notch of the guide groove 4, and the two sides of the push button 3 located outside the guide groove 4 are respectively against the two retaining edges 5. The two retaining edges 5 can be used to limit the push button 3 to avoid the problem of left and right deviation of the push button 3 during the up and down movement.

[0029] In addition, the notch of the guide slot 4 is a rectangular long through hole, and its height is different from that of the guide slot 4. The purpose of this setting is to provide an upper limit position (i.e., the push button 3 moves to the upper end of the long through hole) and a lower limit position (i.e., the push button 3 moves to the lower end of the long through hole) for the push button 3. When the push button 3 moves to the upper limit position, the depth gauge 6 is completely retracted into the guide slot 4; when the push button 3 moves to the lower limit position, the extended length of the depth gauge 6 reaches the maximum length, and the maximum length is generally about 10 cm. Those skilled in the art can also adjust the specific maximum extended length according to actual needs, and are not limited to this size.

[0030] In this embodiment, the material of the push button 3 includes but is not limited to plastic or stainless steel, and other metal materials may also be selected.

[0031] In this embodiment, the outer surface of the push button 3 is provided with an anti-skid texture or a rubber anti-skid layer, the purpose of which is to achieve an anti-skid effect and avoid the problem of slipping when the user pushes the push button 3.

[0032] In this embodiment, the material of the depth gauge 6 is preferably consistent with that of the push button 3, so that they can be manufactured in one piece during the manufacturing process. Therefore, the material of the depth gauge 6 is also plastic or stainless steel.

[0033] In this embodiment, a depth measuring circuit board 7 is provided on one side of the rangefinder body 1 close to the guide groove 4, a depth measuring device is provided on the depth measuring circuit board 7, and a depth measuring reflector 8 is provided on the side of the depth gauge 6 away from the push button 3. The depth measuring device and the depth measuring reflector 8 are used in combination to calculate the extended length of the depth gauge 6.

[0034] The depth measurement circuit board 7 is electrically connected to the screen 2 of the rangefinder body 1. The depth measurement circuit board 7 can transmit the value measured by the depth measurement device to the screen 2, so that the measurement result can be more intuitively seen. Alternatively, a sub-screen can be added, and the depth measurement circuit board 7 is electrically connected to the sub-screen, and the depth measurement value is displayed on the sub-screen, while the original screen 2 only displays the distance measurement value.

[0035] In this embodiment, the depth measuring device is an existing capacitive grid sensor, the moving grid in the capacitive grid sensor is installed on the depth measurement circuit board 7, and the fixed grid in the capacitive grid sensor is installed on the depth measurement reflector 8. In actual use, the emitter on one side of the moving grid emits a driving signal, and the driving signal is transmitted to the depth measurement reflector 8 for reflection, and then returns to the receiving electrode on the side of the moving grid. Through analysis and calculation, the extension length of the depth gauge 6 can be obtained and can be transmitted to the screen 2 in time. This method is an existing capacitive grid displacement measurement method, which is the same as the principle of the existing digital caliper and belongs to the existing mature technology, so its specific structural details will not be further described here. Of course, those skilled in the art can also use grating displacement measurement, Hall magnetic encoder displacement measurement and other methods, and are not limited to this one.

[0036] The advantage of adding a capacitive sensor in this embodiment is that a more accurate measurement structure can be obtained. Currently, the accuracy of the depth gauge 6 is mostly at the 1mm level, but after adding a capacitive sensor, the accuracy can be 0.1mm or even 0.01mm, thereby improving the measurement accuracy.

[0037] In this embodiment, the distance measurement module 9 in the measuring instrument body adopts the laser distance measurement commonly used in existing handheld distance meters, that is, it includes a distance measurement circuit board, and a laser transmitter and a laser receiver are provided on the distance measurement circuit board. The laser emitted by the laser transmitter reaches the object to be measured and then reflects back and is received by the laser receiver. The distance measurement circuit board is also connected to a timer, and the timer calculates the path time of the laser. The distance value can be obtained by the formula: half of the product of the speed of light and the round-trip time. Of course, this is a common distance measurement method in existing handheld distance meters, and it can also be replaced by existing ultrasonic distance measurement and millimeter wave distance measurement, in which laser distance measurement is not limited to the wavelength of light, and ultrasonic and millimeter wave distance measurement are not limited to the emission frequency.

[0038] In addition, there is a power supply module 10 in the measuring instrument body. The power supply module 10 can adopt the existing battery box plus battery method. Of course, technical personnel in this field can also replace it with a common built-in battery pack, a detachable battery pack, and a wireless power supply module 10.

[0039] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
