Description

Technical Field

[0001] The utility model relates to the technical field of button boxes, in particular to a button box. Background Art

[0002] Pushbutton boxes, also known as explosion-proof control boxes, are named for the fact that they house the start and stop functions for remote, centralized control of multiple electrical devices. Because pushbutton boxes involve connecting multiple buttons and control cables, the quality of their structural design directly determines the ease of connection and operational stability.

[0003] The buttons of a button box usually use springs to provide rebound after being pressed. When used for a long time or frequently opened and closed, the mechanical parts of the buttons (springs) are easily damaged, resulting in the buttons being unable to be pressed or rebounding. In the existing technology, the button disassembly and assembly process of the button box is cumbersome, and it is inconvenient to replace the damaged buttons and button accessories. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a button box to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A button box includes a box body and a connecting assembly. The box body is provided with multiple mounting holes, and the box body is provided with multiple mounting grooves connected to the mounting holes at positions corresponding to the mounting holes. A limit ring is installed in the mounting groove, and a button is movably arranged in the limit ring through a spring. A driving rod is movably arranged in the mounting hole. The button is detachably connected to the driving rod through the connecting assembly. The connecting assembly includes a connecting column fixedly installed on the end face of the button and a pair of first protrusions symmetrically arranged on the side faces of the connecting column. An empty slot is provided at the end of the driving rod, and a socket connected to the empty slot is also provided at the end of the driving rod. The side walls of the socket are symmetrically provided with first notches that are plug-in compatible with the first protrusions.

[0007] As a further solution of the present invention: a sealing ring is further sleeved on the connecting column.

[0008] As a further solution of the present invention: a limiting groove is further provided between the mounting hole and the mounting groove, a fixing ring is fixed on the driving rod and is slidably adapted to the limiting groove, a pressure sensor is installed on the fixing ring, and the pressure sensor is electrically connected to the external terminal.

[0009] As a further solution of the present invention: a pair of retaining rings are fixedly installed on the inner wall of the limiting ring, wherein a second notch is symmetrically opened on the retaining ring away from the driving rod, and a second protrusion that is plugged and adapted to the second notch is fixedly provided on the side of the button.

[0010] As a further solution of the present invention: the thread of the limiting ring can be detachably installed in the installation groove.

[0011] As a further solution of the present invention: a baffle is symmetrically fixedly arranged between the two baffle rings.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides a connecting component and a limit component. When the button cannot be pressed or rebounds, the button can be rotated so that the first protrusion coincides with the first notch, thereby realizing the separation of the driving rod and the connecting column. Similarly, after replacing a new button, it is only necessary to align the first protrusion on the side of the connecting column with the first notch at the end of the driving rod. After pressing the knob, the button rotates so that the first protrusion is staggered with the first notch, thereby quickly realizing the connection between the connecting column and the driving rod and realizing the installation of the button. The entire disassembly and assembly process is simple and convenient, and it is convenient to replace the button. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] Example 1

[0021] See also Figure 1-4 , a button box, including a box body 1, and also including a connecting assembly, the box body 1 is provided with a plurality of mounting holes 3, and the box body 1 is provided with a plurality of mounting slots 4 connected thereto at positions corresponding to the mounting holes 3, a limit ring 6 is installed in the mounting slot 4, a button 2 is movably provided in the limit ring 6 through a spring 7, a driving rod 5 is movably provided in the mounting hole 3, the button 2 is detachably connected to the driving rod 5 through the connecting assembly, the connecting assembly includes a connecting column 8 fixedly mounted on the end face of the button 2 and a pair of first protrusions 9 symmetrically arranged on the side of the connecting column 8, an empty slot 10 is provided at the end of the driving rod 5, and a jack communicating with the empty slot 10 is also provided at the end of the driving rod 5, and the side wall of the jack A first notch 11 is symmetrically arranged to be plugged and adapted to the first protrusion 9. By setting a connecting component and a limit component, when the button 2 cannot be pressed or rebounds, the button 2 can be rotated so that the first protrusion 9 coincides with the first notch 11, thereby realizing the separation of the driving rod 5 and the connecting column 8. Similarly, after replacing a new button 2, it is only necessary to match the first protrusion 9 on the side of the connecting column 8 with the first notch 11 at the end of the driving rod 5. After pressing the knob, the button 2 rotates so that the first protrusion 9 is staggered with the first notch 11, thereby quickly realizing the connection between the connecting column 8 and the driving rod 5 and realizing the installation of the button 2. The entire disassembly and assembly process is simple and convenient, and it is convenient to replace the button 2.

[0022] The connecting column 8 is also provided with a sealing ring 12 . The provision of the sealing ring 12 improves the sealing between the button 2 and the limiting ring 6 .

[0023] In addition, a limiting groove 13 is provided between the mounting hole 3 and the mounting groove 4. A fixing ring 14 is fixedly provided on the driving rod 5 and is slidably adapted to the limiting groove 13. A pressure sensor 15 is installed on the fixing ring 14. The pressure sensor 15 is electrically connected to the external terminal. The setting of the limiting groove 13, the fixing ring 14 and the pressure sensor 15 enables the pressure sensor 15 to quickly monitor the information when the button 2 fails to bounce back, and send it to the external terminal to remind the staff to promptly inspect the spring 7 and other components.

[0024] Example 2

[0025] This embodiment is improved on the basis of embodiment 1, specifically:

[0026] See also Figure 2 and Figure 4A pair of retaining rings 16 are also fixedly installed on the inner wall of the limiting ring 6, wherein a second notch 17 is symmetrically provided on the retaining ring 16 away from the driving rod 5, and a second protrusion 18 is fixedly provided on the side of the button 2 to be plugged and adapted to the second notch 17. The retaining ring 16, the second notch 17 and the second protrusion 18 are arranged. During the installation process between the connecting column 8 and the driving rod 5, the alignment of the second protrusion 18 and the second notch 17 can guide the alignment of the first protrusion 9 and the first notch 11, thereby further facilitating the connection between the connecting column 8 and the driving rod 5.

[0027] In order to facilitate the disassembly and assembly of the limiting ring 6 , in this embodiment, the limiting ring 6 is detachably installed in the installation groove 4 via a thread.

[0028] In addition, a baffle 19 is symmetrically fixed between the two baffle rings 16. The setting of the baffle 19 can block the second protrusion 18 on the side of the button 2 when it rotates in the two baffle rings 16. Similarly, it effectively avoids the phenomenon that the first protrusion 9 and the first notch 11 overlap again, causing the driving rod 5 to be separated from the movable rod, thereby further improving the practicality of the connecting component.
