[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a testing fixture for an elevator car top intercom.

[0031] Reference Figures 1-3 An elevator car top intercom testing fixture includes a testing base 1, an intercom body 2 inserted into the outer wall of the testing base 1, a speaker 3 on the surface of the intercom body 2, a button body 4 located below the speaker 3 on the surface of the intercom body 2, a charging plug 5 on the outer wall of the testing base 1, and the intercom body 2 is powered and tested for movement by means of the charging plug 5. A charging socket 6 is provided at the bottom of the intercom body 2 for insertion into the outer wall of the charging plug 5.

[0032] The outer wall of the detection seat 1 is provided with a positioning mechanism, which includes a positioning rod 13 and a telescopic rod 14.

[0033] The side wall of the testing seat 1 is provided with a nut 11, and the inner wall of the nut 11 is threaded with a bolt 12. The bolt 12 drives the telescopic movement of the positioning rod 13. One end of the bolt 12 is rotatably connected to the positioning rod 13. The positioning rod 13 effectively limits and fixes the movement of the walkie-talkie on both sides. The outer wall of the positioning rod 13 is fixedly connected to a telescopic rod 14 that is slidably connected to the side wall of the testing seat 1. The telescopic rod 14 improves the stability of the telescopic movement of the positioning rod 13. The outer wall of the telescopic rod 14 is sleeved with a spring 15 that is fixedly connected to the outer wall of the positioning rod 13. When the walkie-talkie on the top of the elevator car needs to be placed on the testing fixture for testing, in order to improve the stability of the walkie-talkie after it is plugged into the charging plug 5, the bolt 12 is rotated, and the positioning rod 13 fixedly connected to the sliding rod 8 is driven to telescopically move through the limiting action of the nut 11. This causes the positioning rod 13 to limit and fix the walkie-talkie on both sides, thereby improving the stability of the walkie-talkie when placed on the testing fixture for testing.

[0034] Reference Figure 1 The outer wall of the detection base 1 is detachably connected to a decibel meter 7 located on one side of the speaker port 3, which facilitates convenient detection of the sound from the speaker port 3 of the intercom body 2 through the setting of the decibel meter 7.

[0035] Reference Figure 2 The outer wall of the detection base 1 is provided with a miniature electric push rod 10. One end of the miniature electric push rod 10 is fixedly connected to a sliding rod 8 that is slidably connected to the outer wall of the detection base 1. One end of the sliding rod 8 is fixedly connected to a pressing block 9 located on one side of the button body 4. This facilitates the effect of simulating button pressing by setting the pressing block 9. When it is necessary to test the button on the walkie-talkie, the miniature electric push rod 10 is opened. Through the connection of the sliding rod 8, the pressing block 9 is driven to extend and retract, so that the pressing block 9 contacts the button body 4 one by one, achieving the effect of convenient pressing test of the button on the walkie-talkie.

[0036] Reference Figure 2 The pressing block 9 and the button body 4 are set in a one-to-one correspondence, which is conducive to achieving the effect of detecting each button press by means of the one-to-one correspondence between the pressing block 9 and the button body 4.

[0037] Reference Figure 4 The other end of the spring 15 is fixedly connected to the side wall of the detection seat 1, which is beneficial to achieve the effect of automatic reset when the positioning rod 13 is loosened by fixing the other end of the spring 15 to the side wall of the detection seat 1.

[0038] Reference Figure 4The positioning rod 13 is provided in two sets. The positions of the two sets of positioning rods 13 are symmetrical about the central axis of the walkie-talkie body 2. This is beneficial to improve the limiting and fixing effect on both sides of the walkie-talkie body 2 by setting two sets of positioning rods 13 with symmetrical positions about the central axis of the walkie-talkie body 2.

[0039] Reference Figure 4 The outer wall contour of the positioning rod 13 is U-shaped, which is beneficial to improve the stability of the walkie-talkie body 2 during placement and testing.

[0040] The working principle of the elevator car top intercom testing fixture is as follows: When the intercom on the elevator car top needs to be placed on the testing fixture for testing, in order to improve the stability of the intercom after it is plugged into the charging plug 5, the rotating bolt 12, through the limiting action of the nut 11, drives the positioning rod 13, which is fixedly connected to the sliding rod 8, to move in a telescopic motion, so that the positioning rod 13 limits and fixes the two sides of the intercom, thereby improving the stability of the intercom when placed on the testing fixture for testing.

[0041] When it is necessary to test the button on the walkie-talkie, the miniature electric push rod 10 is opened, and the pressing block 9 is driven to extend and retract through the connection of the sliding rod 8, so that the pressing block 9 contacts the button body 4 one by one, achieving the effect of convenient pressing test of the button on the walkie-talkie.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
