Description

Technical Field

[0001] The utility model relates to the technical field of intercoms, and more particularly to a connecting buckle structure of a detachable rear shell of an intercom. Background Art

[0002] A walkie-talkie, also known as a two-way radio, is a portable communication device that uses the propagation of radio signals in the air to achieve point-to-point or point-to-multipoint communication. Since its advent in the 1930s, walkie-talkies have gradually become smaller and easier to carry with the advancement of technology. They are now widely used in various fields and have become an indispensable part of people's daily lives.

[0003] At present, the main function of the back shell of the walkie-talkie is to protect the internal components of the walkie-talkie body. At the same time, it is easy to disassemble and facilitate the staff to repair the walkie-talkie. The existing connecting buckle structure is simple in structure and easy to disassemble and assemble, but its stability is poor. After the walkie-talkie falls, the back shell is easy to fall off from the body, exposing and damaging its internal components. For example, Chinese patent application number: CN202022178234.9, "A connecting buckle structure of a detachable back shell of a walkie-talkie", the connecting buckle structure of the detachable back shell of the walkie-talkie is convenient for installation and disassembly, and is convenient for replacing the battery board of the walkie-talkie, and the back shell is installed tightly and firmly, and is not easy to loosen and fall off. Its purpose is to prevent the back cover from falling off.

[0004] However, although the back cover of this type of walkie-talkie ensures stable performance, it needs to be tilted slightly outward during installation, which affects the installation efficiency. When disassembling, it is necessary to press the buttons on both sides of the shell at the same time and lift it upward. The entire disassembly and assembly process is relatively complicated and requires both hands to perform the disassembly operation. It has great limitations, so it needs to be improved and optimized. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a connecting buckle structure of a detachable rear shell of a walkie-talkie, which has the advantage of strong stability.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, the utility model provides a connecting buckle structure of a detachable rear shell of an intercom, comprising an intercom 1, an operation panel 2 is provided on the front side of the intercom 1, a rear shell 3 is provided on the rear side of the intercom 1, and the intercom 1 and the rear shell 3 are rotatably connected by a hinge 4;

[0028] A card slot 5 is provided on the rear side of the intercom 1. Expansion slots 6 are provided on both the left and right sides of the card slot 5. Card blocks 7 are movably mounted inside the two sets of expansion slots 6. The card blocks 7 and expansion slots 6 are elastically connected via springs 8. Mounting slots 9 are provided on the left and right sides of the rear housing 3. Two sets of card blocks 7 extend through the mounting slots 9 and secure the rear housing 3.

[0029] Guide grooves 10 are provided on both sides of the interior of the mounting groove 9, and sliders 12 are movably installed inside the guide grooves 10. A stop block 11 is fixedly installed between the two groups of sliders 12. A control groove 13 is provided below the mounting groove 9, and a push rod 14 is movably installed inside the control groove 13. The push rod 14 and the inner wall of the control groove 13 are elastically connected by a spring 2 15, and a transmission head 16 is fixedly installed on the top of the push rod 14.

[0030] When the rear shell 3 needs to be disassembled, the staff picks up the intercom 1 and pushes the control rod 18 upward along the straight groove 17 with their fingers. At this time, the push rod 14 moves synchronously with the control rod 18, so that the top of the transmission head 16 and the stop block 11 abut against each other, and through the inclined design of the transmission head 16 and the stop block 11, when the transmission head 16 moves upward, the stop block 11 is pushed to both sides by the transmission head 16. Further, the stop block 11 moves along the guide groove 10 to the outside of the installation groove 9 through the slider 12, and pushes the two groups of blocks 7, so that the blocks 7 are stored in the interior of the telescopic groove 16. At this time, the top plate 20 will bounce the top of the rear shell 3 through the elastic potential energy of the spring three 21. At this time, the rear shell 3 is completely disassembled. When installing, the staff releases the control lever 18 to reset the push rod 14 by the spring 2 15, and then presses the rear shell 3 to cover the rear side of the intercom 1. When the rear shell 3 is pressed, the outer walls on both sides of the rear shell 3 will squeeze the block 7 into the interior of the telescopic slot 1 6 through the inclined surface of the block 7. After the rear shell 3 is fully installed, the block 7 will be reset by the elastic potential energy of the spring 1 8, so that the block 7 enters the interior of the installation slot 9, so that the rear shell 3 is firmly installed. After the installation of the rear shell 3 is completed, the top plate 20 will always give the rear shell 3 an upward pop-up force through the elastic potential energy of the spring 3 21. Through this force, the friction between the installation slot 9 and the block 7 is increased, further ensuring the stability of the installation.

[0031] By pushing the control rod 18, the transmission head 16 pushes the block 11 to the left and right sides, further allowing the block 7 to be stored in the interior of the telescopic slot 6 to complete the disassembly, and then by pressing the rear shell 3, the rear shell 3 enters the interior of the card slot 5, and the two groups of blocks 7 enter the interior of the installation slot 9 to complete the disassembly. Compared with the traditional device, this device is installed by pressing the rear shell 3 and is dismantled by pushing the control rod 18, which ensures quick disassembly and assembly. At the same time, the rear shell 3 is firmly fixed by the two groups of blocks 7 to prevent the rear shell 3 from falling due to external force impact, thereby improving the protection effect of the rear shell 3.

[0032] Among them, the front side of the card slot 5 is provided with a telescopic slot 2 19;

[0033] A top plate 20 is movably installed inside the second telescopic slot 19 . The top plate 20 and the inner wall of the second telescopic slot 19 are elastically connected via a third spring 21 . The top of the top plate 20 and the rear shell 3 abut against each other.

[0034] When the rear shell 3 is disassembled, the top plate 20 will bounce up the top of the rear shell 3 through the elastic potential energy of the spring three 21 to complete the disassembly. After the rear shell 3 is installed, the top plate 20 will always give the rear shell 3 an upward pop-up force through the elastic potential energy of the spring three 21. Through this force, the friction between the installation slot 9 and the block 7 is increased, further ensuring the stability of the installation.

[0035] Through the elastic potential energy of the spring three 21, the top plate 20 automatically pops out the top of the back shell 3 when the back shell 3 is disassembled, thereby improving the convenience of disassembly. After the back shell 3 is installed, the top plate 20 always gives the back shell 3 an upward pop-up force, so that the inner wall of the installation groove 9 and the block 7 abut against each other, increasing the friction between the installation groove 9 and the block 7, improving the stability of the installation of the back shell 3, and further preventing the back shell 3 from loosening.

[0036] One end of the abutting block 11 abuts against the clamping block 7 , and the other end of the abutting block 11 abuts against the transmission head 16 .

[0037] When the transmission head 16 is operated, the stop block 11 is displaced toward the outside of the installation slot 9 along the guide slot 10 through the slider 12 , and pushes the two groups of clamping blocks 7 so that the clamping blocks 7 are accommodated in the interior of the telescopic slot 1 6 .

[0038] The inclined surfaces of the two groups of abutting blocks 11 are opened in a direction parallel to the inclined surface of the transmission head 16 , and the inclined surface of the clamping block 7 is opened toward the rear side.

[0039] The design of the inclined surface ensures stable transmission between the transmission head 16 and the stop block 11 .

[0040] A straight groove 17 is formed on the outer wall of the rear shell 3 , and a control rod 18 is movably installed inside the straight groove 17 . The control rod 18 is fixedly connected to the push rod 14 .

[0041] The staff can control the displacement of the push rod 14 through the control rod 18 to achieve the disassembly of the rear shell 3.

[0042] The second guide grooves 22 are formed on both the left and right sides of the second expansion slot 19 , and both ends of the top plate 20 are movably mounted inside the second guide grooves 22 .

[0043] The top plate 20 is prevented from deflecting by the guide limit of the second guide groove 22 .

[0044] The working principle and use process of this utility model:

[0045] When the rear shell 3 needs to be disassembled, the staff picks up the intercom 1 and pushes the control rod 18 upward along the straight groove 17 with their fingers. At this time, the push rod 14 moves synchronously with the control rod 18, so that the top of the transmission head 16 and the stop block 11 abut against each other, and through the inclined design of the transmission head 16 and the stop block 11, when the transmission head 16 moves upward, the stop block 11 is pushed to both sides by the transmission head 16. Further, the stop block 11 moves along the guide groove 10 to the outside of the installation groove 9 through the slider 12, and pushes the two groups of blocks 7, so that the blocks 7 are stored in the interior of the telescopic groove 16. At this time, the top plate 20 will bounce the top of the rear shell 3 through the elastic potential energy of the spring three 21. At this time, the rear shell 3 is completely disassembled. When installing, the staff releases the control lever 18 to reset the push rod 14 by the spring 2 15, and then presses the rear shell 3 to cover the rear side of the intercom 1. When the rear shell 3 is pressed, the outer walls on both sides of the rear shell 3 will squeeze the block 7 into the interior of the telescopic slot 1 6 through the inclined surface of the block 7. After the rear shell 3 is fully installed, the block 7 will be reset by the elastic potential energy of the spring 1 8, so that the block 7 enters the interior of the installation slot 9, so that the rear shell 3 is firmly installed. After the installation of the rear shell 3 is completed, the top plate 20 will always give the rear shell 3 an upward pop-up force through the elastic potential energy of the spring 3 21. Through this force, the friction between the installation slot 9 and the block 7 is increased, further ensuring the stability of the installation.
