Description

Technical Field

[0001] The utility model relates to the field of digital intercoms, in particular to a digital intercom. Background Art

[0002] Digital walkie-talkies are designed using digital technology. They digitize voice signals and transmit them in digitally coded form, meaning all modulation on the walkie-talkie's transmission frequency is digital.

[0003] The basic principle of a digital walkie-talkie is to convert analog voice into a digital signal, which is then modulated onto a radio frequency. Since the signal is digital, it can also transmit data directly. The emergence of digital walkie-talkies is also aimed at conserving radio spectrum. Therefore, digital walkie-talkies typically use a 6.25kHz bandwidth per voice channel, which is half the bandwidth of a typical analog walkie-talkie.

[0004] Currently, most existing digital walkie-talkies are handheld and can only be placed in a pocket or held in the hand when carried. This is inconvenient to carry in some complex working environments and may cause the walkie-talkie to fall and break, affecting normal use. Therefore, there is an urgent need for a digital walkie-talkie that is easy to carry. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 4 As shown, a digital intercom, comprising:

[0026] The fuselage 1 has a slide groove 2 on the outer wall of both sides of the fuselage 1, and a bottom groove 3 is opened at the bottom end. The two ends of the bottom groove 3 are connected to the slide groove 2. The inner wall of the slide groove 2 close to the side of the fuselage 1 is provided with an inner groove, and a slider 4 is slidably installed inside. The slider 4 is slidably penetrated by a pull rod 6. The pull rod 6 is fixedly installed with a baffle 7 at one end facing the fuselage 1, and the outer wall is sleeved with a spring 8. The spring 8 is located between the baffle 7 and the slider 4. A turntable 9 is provided on the side of the slider 4 away from the fuselage 1. A nylon belt 5 is fixedly installed on the outer wall of the turntable 9. A slide groove 2 and a bottom groove for accommodating the nylon belt 5 are provided on the side, and the position of the nylon belt 5 is limited by the cooperation of the pull rod 6, the spring 8 and the baffle 7, so that when the digital walkie-talkie is in use, the nylon belt 5 can be released by moving the slider 4. The digital walkie-talkie can be worn on the user's arm through the nylon belt 5, which plays a role in portability and solves the problems of easy falling and inconvenience in holding when placed in a pocket. At the same time, the nylon belt 5 can also be stored and hidden when not in use, which neither affects the appearance nor is damaged by pulling due to the external placement of the nylon belt 5.

[0027] In some embodiments, a PIT button is provided on the side wall of the chassis 1, and a dual-band receiver is housed within the chassis 1. This allows for receiving information from a designated working channel while on a broadcast channel, and allows for direct reply using the PIT button without changing the channel within a specified timeframe. For example, utilizing this digital intercom can effectively facilitate station management, cultural awareness campaigns, and emergency response. It also significantly improves passenger boarding and disembarking efficiency, enabling staff to better serve passengers, enhancing work efficiency and passenger satisfaction, while also achieving the crucial goal of reducing equipment burden and improving quality and efficiency.

[0028] In some embodiments, a receiving groove is opened on the side of the slider 4 facing the fuselage 1. The receiving groove is set to be circular and the diameter is the same as the diameter of the inner groove. The receiving groove is used to accommodate the spring 8 and the baffle 7, so that when the slider 4 is moved, the spring 8 and the baffle 7 are prevented from causing movement interference and affecting the release of the nylon belt 5. Since the baffle 7 is also set to be circular and has the same diameter as the receiving groove, the baffle 7 can be moved into the receiving groove. The thickness of the spring 8 in the compressed state is less than the depth of the receiving groove, and space can be reserved for the baffle 7 to enter the receiving groove, preventing the slider 4 from failing to move normally due to the baffle 7 not entering the receiving groove. Setting the diameter of the pull rod 6 to be smaller than the diameter of the receiving groove can prevent the pull rod 6 from escaping from the slider 4 when driving the baffle 7 to move.

[0029] In some embodiments, the turntable 9 is provided in two groups and is respectively slidably mounted inside the slide groove 2 on both sides of the fuselage 1. The slider 4 is used to drive the nylon belt 5 to move and adjust the wearing position of the user. At the same time, the turntable 9 is rotatably mounted on the outer wall of the pull rod 6 and is located outside the slider 4, so that the turntable 9 can drive the nylon belt 5 to rotate on both sides of the fuselage 1 for easy wearing. The two groups of turntables 9 are connected by the nylon belt 5 to form a closed loop, so that the digital walkie-talkie can be worn on the user's arm.

[0030] In some embodiments, the depth of the bottom groove 3 and the depth of the slide groove 2 are the same as the thickness of the nylon belt 5, so that the nylon belt 5 can be stored in the bottom and both sides of the fuselage 1 when not in use, playing a storage role without affecting the appearance, and at the same time avoiding the pulling damage caused by the external placement of the nylon belt 5.

[0031] In some embodiments, a limit block 10 is fixedly installed at the bottom of the slide groove 2. The function of the limit block 10 is to prevent the slider 4 from falling out of the slide groove 2 during movement, causing the nylon belt 5 to fall off, thereby playing a limiting role.

[0032] Working principle: When in use, pull the pull rod 6 toward the outside of the fuselage 1, and the pull rod 6 drives the baffle 7 to move from the inner groove to the inside of the accommodating groove, and compresses the spring 8 at the same time. At this time, the baffle 7 does not affect the movement of the slider 4. Move the slider 4 downward, driving the turntable 9 on its outer wall to move downward, and the nylon belt 5 also moves downward, thereby releasing the nylon belt 5. Then, when rotating the nylon belt 5, the turntable 9 rotates on the outer wall of the pull rod 6. The user can wear the digital walkie-talkie by passing his arm through the nylon belt 5. When storing the nylon belt 5, push the slider 4 upward to the top of the slide groove 2. When the accommodating groove is aligned with the inner groove, the baffle 7 loses its obstruction, the spring 8 is released, and the baffle 7 is pushed into the inner groove, completing the limit of the slider 4, so that the nylon belt 5 is stored in the bottom groove 3 and the inside of the slide groove 2, thereby completing the storage.

[0033] The slider, baffle, spring and nylon belt are all universal standard parts or are known through conventional experimental methods, so they will not be described in detail here.

[0034] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, and these changes and improvements will fall within the scope of the utility model to be protected.
