Description

Technical Field

[0001] The utility model relates to a competition answering machine, belonging to the field of answering machines. Background Art

[0002] A buzzer is a device used in competitions, games, or educational activities to quickly determine which participant pressed a button first. A wired buzzer is a type of buzzer. Its advantages include high reliability and fast response. Wired buzzers connect individual buttons to a main controller via cables, making them suitable for competitions in fixed locations. Wired buzzers are often installed in a circular opening on a tabletop using screws, wherein the dome cover of the wired buzzer is above the tabletop, and the round bottom box of the wired buzzer is installed below the tabletop by multiple screws. At least two fixing holes for inserting screws are installed on the surface of the round bottom box, so that the screws pass through the fixing holes and are connected to the tabletop by self-tapping, thereby restricting the position of the wired buzzer. However, the spacing between the fixing holes for installing the screws on the round bottom box and the round bottom box is fixed, and the area where the screws are connected to the tabletop cannot be adjusted as needed. That is, the screws that limit the position of the round bottom box are close to the inner wall of the circular opening. For plates with poor crack resistance, during the self-tapping process of the screws, the area of ​​the plate near the circular opening is cracked under the action of the self-tapping screws. Therefore, it is necessary to design a competition buzzer that can adjust the installation position of the buzzer as needed. Utility Model Content

[0012] 2. Adjust the length of the rectangular plate in the rectangular tube to increase the distance between the fixing hole and the round bottom box, and then use the positioning screws to limit the relative position of the rectangular plate and the rectangular tube, so that the fixing hole is away from the round opening on the desktop for inserting the round bottom box. When installing the screws in the fixing hole, the screws will not cause the area of ​​the desktop near the round opening with poor crack resistance to crack during the self-tapping process, so that the installation position of the buzzer can be adjusted as needed.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The utility model provides a technical solution: a competition buzzer, including a round-bottom box 1, an inner tube 2 is inserted in the round-bottom box 1, an external threaded tube 13 is installed at the bottom of the inner tube 2, the external threaded tube 13 passes through the round-bottom box 1 and is threadedly connected with a nut 14, and the nut 14 is arranged on the lower side of the round-bottom box 1. After the external threaded tube 13 passes through the round-bottom box 1, the nut 14 is screwed on the external threaded tube 13 to complete the assembly of the inner tube 2 and the round-bottom box 1.

[0024] See Figure 1-Figure 7, a button switch 12 is inserted into the external threaded tube 13, a pressure plate 15 is slidably installed in the inner tube 2, and a plug sleeve 16 is connected and fixed to the middle position of the lower surface of the pressure plate 15. The plug sleeve 16 is inserted into the external threaded tube 13 and the plug sleeve 16 is clamped with the external threaded tube 13, wherein two clamping plates 17 are symmetrically installed at the lower end of the plug sleeve 16, and the clamping plate 17 is an L-shaped structure. Two clamping grooves are symmetrically opened at the lower end of the external threaded tube 13, so that the clamping plate 17 passes through the external threaded tube 13, and the horizontal part of the clamping plate 17 is clamped in the clamping groove, completing the clamping of the plug sleeve 16 and the external threaded tube 13, that is, the pressure plate 15 is restricted In the inner cylinder 2, the upper end of the push button switch 12 extends into the plug-in sleeve 16, and the pressure plate 15 is provided with a dome cover 3 that is plugged into the pressure plate 15. The dome cover 3 is inserted in the inner cylinder 2. Two protrusions are symmetrically installed on the outer surface of the dome cover 3. Both sides of the two protrusions are provided with limit parts, which are connected and fixed to the pressure plate 15. The protrusions and the limit parts cooperate with each other to prevent the dome cover 3 from rotating around the pressure plate 15 at will. When the dome cover 3 is pressed, the dome cover 3 drives the pressure plate 15 to move downward, and the pressure plate 15 drives the plug-in sleeve 16 to move along the external threaded tube 13, and then the pressure plate 15 squeezes the contact part of the push button switch 12.

[0025] See 1- Figure 3 The round bottom box 1 is provided with two limiting rings 4 connected and fixed with the round bottom box 1, and two semicircular rings 6 that can form a ring-shaped structure are provided between the two limiting rings 4. The semicircular rings 6 are sleeved on the round bottom box 1 and in sliding contact with the round bottom box 1. The ends of the two semicircular rings 6 are connected to each other, that is, the contact parts of the ends of the two semicircular rings 6 are provided with arc plates 5, and the arc plates 5 are connected and fixed with the two semicircular rings 6 by glue. The arc plates 5 play the role of connecting the two semicircular rings 6, so that the structure formed by the two semicircular rings 6 is sleeved on the round bottom box 1, and the two semicircular rings 6 are connected by two arc plates 5. At this time, the structure formed by the two semicircular rings 6 is between the two limiting rings 4, which realizes the restriction on the structure formed by the two semicircular rings 6, so that the structure formed by the two semicircular rings 6 rotates around the round bottom box 1, which is convenient for adjusting the orientation of the structure formed by the rectangular tube 7 and the rectangular plate 9 as needed.

[0026] See 1- Figure 3The middle position of the outer surface of the two semicircular rings 6 is connected and fixed with a rectangular tube 7, and a rectangular plate 9 is inserted in the rectangular tube 7. The end of the rectangular plate 9 on the outside of the rectangular tube 7 is provided with a fixing hole 11 for inserting a screw. The end of the rectangular tube 7 away from the semicircular ring 6 is threadedly connected with a positioning screw 8 for limiting the relative position of the rectangular plate 9 and the rectangular tube 7. The end of the rectangular plate 9 on the outside of the rectangular tube 7 is connected and fixed with a pad 10. The side of the pad 10 away from the rectangular plate 9 is flush with the side of the rectangular tube 7. The pad 10 and the rectangular tube 7 jointly support the two ends of the rectangular plate 9. Adjust the length of the rectangular plate 9 in the rectangular tube 7 to increase the spacing between the fixing hole 11 and the round bottom box 1. Then, use the positioning screw 8 to limit the relative position of the rectangular plate 9 and the rectangular tube 7, so that the fixing hole 11 is away from the circular opening on the desktop for inserting the round bottom box 1. When the screw is installed in the fixing hole 11, the screw will not cause the area of ​​the desktop with poor crack resistance near the circular opening to crack during the self-tapping process, thereby adjusting the installation position of the buzzer as needed.
