Description

Technical Field

[0001] The utility model relates to the technical field of screen door thresholds, in particular to a fully composite insulating threshold for a screen door. Background Art

[0002] There is a potential difference between the shielding doors on subway trains and platforms and the ground. When the subway train arrives at the station, passengers and drivers will come into contact with the door structure of the shielding door system when entering and exiting the train doors and platform shielding doors. If the door structure is not insulated, a step voltage (90-130V) will be generated, which will pose a risk of electric shock to people. According to the relevant insulation and equipotential requirements of urban rail transit platform design, the shielding door system will be insulated. Due to the complex structure of the shielding door system, there is a risk of electric shock when people get on and off the train due to insulation failure.

[0003] According to a fully composite insulating threshold for a shielded door disclosed on the patent website (authorization announcement number: CN210317011U), it is described as "a fully composite insulating threshold for a shielded door, comprising two threshold panels made of stainless steel or aluminum alloy, two fully composite insulating thresholds made of Aisaifei, and a threshold support base composed of metal components. The above insulating thresholds are tubular with a rectangular cross-section, and the two insulating thresholds are arranged side by side. The two threshold panels are respectively wrapped around the upper end surfaces of the two insulating thresholds. The threshold support base is arranged below the two insulating thresholds. The utility model has excellent insulation performance. After the structure is completed, the measured resistance value is far greater than 0.5 megohms, ensuring operational safety. The construction is simple, the installation method is consistent with other metal types of thresholds, and the construction cost is low. Compared with other existing metal threshold insulation methods, the insulation performance is more stable. Compared with the original iron threshold, it has corrosion resistance and its durability can reach more than 30 years."

[0004] Based on the above, the applicant believes that the following defects exist:

[0005] The fully composite insulating threshold of the shield door includes two threshold panels made of stainless steel or aluminum alloy, two fully composite insulating thresholds made of Esaifei and a threshold support base made of metal components. Compared with other existing metal threshold insulation methods, the insulation performance is more stable. Compared with the original iron threshold, it has corrosion resistance and its durability can reach more than 30 years. However, the threshold is not equipped with corresponding shock-absorbing protection components. During long-term use, it will often be compressed, which will cause damage to the threshold over time, affecting the passage of passengers. Utility Model Content

[0025] The utility model provides the following technical solutions:

[0026] For example 1, please refer to Figure 1-4 A fully composite insulating threshold of a shielded door includes a mounting base 1, a protective mounting mechanism 4 is provided on the top of the mounting base 1, and an insulating anti-slip mechanism 5 is provided on the top of the protective mounting mechanism 4;

[0027] The protective mounting mechanism 4 includes a reinforcing rib 41, which is arranged on the top of the mounting seat 1.

The top of the reinforcing rib 41 is fixedly connected to a damping telescopic column 42, and a spring 43 is provided on the surface of the damping telescopic column 42. The left and right ends of the top of the reinforcing rib 41 are fixedly connected to a fixing seat 44. A sliding rod 45 is fixedly connected to the inside of the fixing seat 44.

When a passenger passes through the threshold, the top plate 401 is pressed, driving the top plate 401 to descend.

At the same time, the connecting arm 49 at the bottom of the connecting seat 48 presses the slider 46 to slide on the surface of the slide rod 45. The auxiliary springs 47 on both sides can further improve the stability of the threshold, effectively preventing the threshold from being damaged under long-term use, thereby further improving the service life and service life of the threshold.
