Description

Technical Field

[0001] The utility model belongs to the field of callers, in particular to a composite trigger mechanism for a one-key caller. Background Art

[0002] At present, in a caller, multiple components are usually used in combination to trigger a pull-cord caller. The working process is complex, and once a component fails to work properly, it will affect the normal operation of the caller. Therefore, it is necessary to provide an integral composite trigger mechanism to facilitate the flexible triggering of the pull-cord caller. In addition, since the internal wires of a push-button caller are loose and prone to deflection, there is a lack of a wire pressing and fixing device.

[0003] Chinese Patent CN219162777U discloses a caller. One end of a pull cord is connected to a rotating bar, and the other end of the pull cord extends out of the housing. When the pull cord is pulled, the rotating bar can drive a trigger member to rotate, so that a response occurs between the trigger member and a control member, driving the control member to work to trigger and start the call function. One end of its reset assembly is connected to a partition, and the other end of the reset assembly is connected to the rotating bar. When the pull cord is not stressed, the reset assembly drives the rotating bar to reset. The reset assembly can adopt an elastic element such as a spring, and the rotating bar can be quickly reset through the reset assembly.

[0004] This patent realizes the reset of the rotating bar through multiple components such as the rotating bar, the trigger member, and the reset assembly connected to the rotating bar. It operates step by step according to the operation of each part and sequentially, and the working process is complex, time-consuming and laborious. In addition, the structures such as the rotating bar and the reset assembly of this patent are only applicable to pull-cord callers and not applicable to push-button callers, and the application range is not wide.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0032] As Figures 1-9 shown, the present utility model provides a composite trigger mechanism for a one-key call device, including: two pressing plates 1 and a trigger frame 2.

[0033] As Figures 1-2 shown, the two pressing plates 1 are parallelly installed on the housing of the one-key call device, and the distance between the two pressing plates 1 is 13 mm to 14 mm. In the present utility model, the parallelly arranged pressing plates 1 can limit the movement range of the trigger frame 2 and ensure the normal return of the trigger frame 2. Specifically, the pressing plate 1 includes a horizontal plate 11 and a vertical plate 12, the inner side surface of the horizontal plate 11 is in contact with the trigger frame 2, and the outer side surface of the horizontal plate 11 is connected to the vertical plate 12. The horizontal plate 11 is in contact limit with the pressing plate 1, and the vertical plate 12 supports and fixes the horizontal plate 11.

[0034] As Figures 1-2 shown, the trigger frame 2 is installed between the two pressing plates 1, and the length of the trigger frame 2 is 31 mm to 32 mm. As Figures 3-5 shown, the trigger frame 2 includes a main body rod 21 and elastic pressing pieces 22 distributed on both sides of the main body rod 21. The main body rod 21 has a first end and a second end. The first end of the main body rod 21 has a pulling rope perforation 211, and the second end of the main body rod 21 has an extension section 212, and the extension section 212 extends forward along the side surface of the trigger frame 2.Figures 4-5 As shown, a groove 23 is formed on the second end of the main body rod 21, making the second end of the main body rod 21 lighter. According to the lever principle, the second end of the main body rod 21 can be easily lifted, and at the same time, materials can be saved to avoid unnecessary waste.

[0035] As Figures 6-7 As shown, in a specific embodiment, a positioning post 3 is installed on the housing of the one-key pager. The middle part of the main body rod 21 of the trigger frame 2 has a mounting hole 213, and the diameter of the mounting hole 213 is the same as the outer diameter of the positioning post 3. The main body rod 21 of the trigger frame 2 can be sleeved on the positioning post 3. The trigger frame 2 of the present invention rotates around the positioning post 3 and cooperates with the movement of the pull rope 4 to realize the triggering of the switch and the return of the trigger frame 2. A top plate 31 is further provided at the bottom end of the positioning post 3. Specifically, there are 4 top plates 31 at the bottom end of the positioning post 3, which are distributed in a cross shape around the positioning post 3 for uniform support. The top plate 31 at the bottom end of the positioning post 3 can prevent the trigger frame 2 from directly contacting the housing of the one-key pager, reduce friction, avoid directly hindering the rotation of the trigger frame 2, and reduce the wear between the trigger frame 2 and the housing of the one-key pager.

[0036] The composite trigger mechanism of the one-key pager of the present invention is used for a pull-rope type pager or a button type pager.

[0037] As Figure 8 As shown, when applied to a pull-rope type pager, the pull rope perforation 211 at the first end of the main body rod 21 is connected to the pull rope 4. When the pull rope 4 is pulled, the first end of the main body rod 21 is pressed down, and the elastic pressing piece 22 at the lower end is in full contact with the pressure plate 1. At the same time, the second end of the main body rod 21 is lifted to press the switch above the second end of the main body rod 21; when the pull rope 4 is released, the elastic pressing piece 22 rebounds to drive the trigger frame 2 to reset. Among them, the housing of the one-key pager, the pressure plate 1 and the trigger frame 2 are all made of plastic materials.

[0038] As Figure 9 As shown, when applied to a button type pager, one end of the button wire 5 is connected to the button assembly 6 and extends into the housing, bypasses the positioning post 3 of the trigger frame 2 and is connected to the circuit board. The trigger frame 2 installed in the housing presses and fixes the button wire 5 of the button type pager to prevent the button wire 5 from swinging or shifting, thereby avoiding pulling the button wire 5 at the circuit board, resulting in effects such as poor contact or stop of operation, which affect the working efficiency.

[0039] The usage method of the present invention is as follows:

[0040] If it is installed in a pull-cord type call device, when the pull cord 4 is pulled, it will drive the trigger frame 2 to rotate and trigger the switch, realizing the opening or closing of the pull-cord type call device; since the elastic pressing piece 22 has elasticity, when the lower elastic pressing piece 22 is in full contact with the pressing plate 1, deformation will occur. When the pull cord 4 is released, the elastic pressing piece 22 rebounds, and the trigger frame 2 resets between the two pressing plates 1; if it is installed in a push-button type call device, the push-button wire 5 bypasses the positioning post 3 of the trigger frame 2, and the trigger frame 2 presses and fixes the push-button wire 5 below the trigger frame 2, preventing the push-button wire 5 from swinging or shifting, thereby avoiding pulling the push-button wire 5 at the circuit board, resulting in effects such as poor contact or stop of operation, which affects the work efficiency.

[0041] Through the integrated trigger frame 2 and the pressing plate 1 that realizes the limiting function of the present utility model, not only can the flexible triggering of the switch of the pull-cord type call device be realized, but also the push-button wire 5 can be pressed and fixed to prevent the push-button wire 5 from swinging and shifting, thereby avoiding pulling the push-button wire 5 at the circuit board, causing poor contact or stop of operation of the push-button type call device, which affects the normal operation of the work; it can be installed in both the pull-cord type call device and the push-button type call device, with a wide application range and various effects.

[0042] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
