Description

Technical Field

[0001] This utility model relates to the field of handheld laser rangefinder technology, and more specifically, to a dual-power golf rangefinder. Background Technology

[0002] Rangefinders utilize the principle of pulse ranging, measuring distance based on the time-of-flight difference of laser light. They take advantage of the extremely short duration of laser pulses and the relatively concentrated energy over time, enabling them to achieve long ranges and accurately measure distances to objects. For example, Chinese patent document CN115421149A discloses a laser rangefinder. According to its specification and accompanying drawings, existing golf rangefinders mostly use a single battery power supply. When the battery is depleted, it must be replaced or recharged, which is insufficient for prolonged use, special situations, or emergencies, limiting the usability of such rangefinders. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a dual-power golf rangefinder, which aims to solve the problems in the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-power golf rangefinder, including a main body, a dry battery compartment is provided on one side of the main body, and a lithium battery is also provided inside the main body. The dry battery compartment and the lithium battery are connected through a battery conversion switch.

[0005] In the aforementioned dual-power golf rangefinder, an eyepiece is provided at one end of the main body, and an objective lens mount is provided at the other end. An objective lens is installed within the objective lens mount, a laser emitter is located at the lower end of the objective lens, and a laser receiver is located at the lower end of the lithium battery. Distant objects can be observed through the eyepiece and objective lens, and distance measurement can be performed using the laser emitter and laser receiver.

[0006] In the aforementioned dual-power golf rangefinder, a dust cover slot is provided below the objective lens on the main body. The battery switch is located within the dust cover slot, and a charging port is located below the battery switch within the dust cover slot. A dust cover is detachably mounted on the dust cover slot. The dust cover protects the charging port and battery switch by covering the dust cover slot, and also prevents accidental button presses.

[0007] In the aforementioned dual-power golf rangefinder, an insertion hole is provided in the dust cover groove. A corresponding insertion rod is provided on the side of the dust cover near the dust cover groove, and a protruding limiting ring is provided on the insertion rod, which is located within the insertion hole. By inserting the insertion rod into the insertion hole, the limiting ring prevents the dust cover from falling out after the dust cover groove is opened.

[0008] In the aforementioned dual-power golf rangefinder, the connector rod is made of silicone.

[0009] In the aforementioned dual-power golf rangefinder, the outer diameter of the limiting ring is larger than the inner diameter of the insertion hole; in the aforementioned dual-power golf rangefinder, a battery compartment cover is provided on the dry battery compartment.

[0010] The beneficial effects of this utility model are as follows: by allowing the dry battery compartment to be detached and installed with dry batteries, it can be powered by dry batteries while simultaneously switching to lithium batteries via a battery conversion switch, thus achieving a dual power supply method, which greatly improves the usage time of the rangefinder. Moreover, after the lithium battery and dry battery are depleted, the dry batteries can be removed and replaced, unlike traditional rangefinders that can only be charged after the power is depleted, making the rangefinder more versatile in its usage environment.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Combination Figures 1 to 4 The illustrated dual-power golf rangefinder includes a main body 1, with a dry battery compartment 9 on one side of the main body 1. A lithium battery 17 is also housed inside the main body 1. The dry battery compartment 9 and the lithium battery 17 are connected via a battery conversion switch 6. In this embodiment, the dry battery compartment 9 can be detached to accommodate a dry battery 10. While the dry battery 10 provides power, the lithium battery 17 can be switched to be used via the battery conversion switch 6, thus achieving a dual-power supply method. This significantly extends the rangefinder's operating time. Furthermore, after both the lithium battery 17 and the dry battery 10 are depleted, the dry battery 10 can be removed and replaced, unlike traditional rangefinders which require charging after depletion. This diversifies the rangefinder's operating environment.

[0018] The battery switch 6 in this embodiment is existing technology. It switches between dual power supplies. The battery switch 6 is available on the market, and its internal structure will not be described in detail.

[0019] In this embodiment, an eyepiece 2 is provided at one end of the main body 1, and an objective lens mount 3 is provided at the other end. An objective lens 13 is installed in the objective lens mount 3. A laser emitter 14 is provided at the lower end of the objective lens 13, and a laser receiver 15 is provided at the lower end of the lithium battery 17. Distant objects can be observed through the eyepiece 2 and the objective lens 13. The laser emitter 14 and the laser receiver 15 can be used for distance measurement. The specific distance measurement principle is existing technology and will not be described in detail here.

[0020] By switching between dual power supplies to power the laser transmitter 14 and the laser receiver 15, the operating time of the rangefinder is greatly extended.

[0021] In this embodiment, a dust cover groove 4 is provided below the objective lens 13 on the body 1. The battery conversion switch 6 is disposed in the dust cover groove 4. A charging port 7 is provided below the battery conversion switch 6 and located in the dust cover groove 4. A dust cover 11 is detachably disposed on the dust cover groove 4. The charging port 7 can be a Type-C charging port, which has higher applicability. The dust cover 11 can cover the dust cover groove 4, thereby protecting the charging port 7 and the battery conversion switch 6, and also preventing accidental button presses.

[0022] In this embodiment, a socket 5 is provided in the dust cover groove 4. A plug rod 12 corresponding to the socket 5 is provided on the side of the dust cover 11 near the dust cover groove 4. A protruding limiting ring 16 is provided on the plug rod 12, and the limiting ring 16 is located in the socket 5. By inserting the plug rod 12 into the socket 5, the limiting ring 16 is used to prevent the dust cover groove 4 from falling out after it is opened.

[0023] It is worth noting that in this embodiment, the plug rod 12 is made of silicone, so that even if the dust cover 11 swings after it is opened, it will not affect the operation inside the dust cover groove 4. In addition, the outer diameter of the limiting ring 16 is larger than the inner diameter of the socket 5. And because the plug rod 12 is made of silicone, it is easy for the plug rod 12 to be inserted into the socket 5. At the same time, when the dust cover 11 is separated from the dust cover groove 4, it can also prevent the plug rod 12 from completely detaching from the socket 5, thereby preventing the dust cover 11 from falling off.

[0024] In this embodiment, a battery compartment cover 8 is provided on the dry battery compartment 9 to protect the dry battery 10.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
