Problems solved by technology

In many cases, in order to facilitate the entry and exit of equipment, vehicles and personnel, the threshold has to be canceled when designing the sound insulation door, which will have a great adverse effect on the overall sound insulation of the sound insulation door
At present, for soundproof doors without a threshold, the gap between the door and the ground is usually sealed with a sealing strip to block the noise. However, the sound insulation of the sealing strip is far lower than that of the soundproof door panel, which in turn causes the overall sound insulation of the door Decline

Embodiment 1

[0037] figure 1 with figure 2 They are respectively structural schematic diagrams of the threshold structure and the lock structure disclosed in the embodiment of the present invention.

[0038] See figure 1 with 2 A threshold structure is provided in a preferred embodiment of the present invention. Specifically, the threshold structure includes a lift threshold assembly 20 and a threshold base 80. The lift threshold assembly 20 includes:

[0039] The first cylinder 30 has an upper top;

[0040] The second cylinder 60 has a lower bottom, and the second cylinder 60 is sleeved in the first cylinder 30;

[0041] The coil spring 40 is located in the first cylinder 30 and the second cylinder 60, and the two ends of the coil spring 40 abut against the upper top of the first cylinder 30 and the lower bottom of the second cylinder 60 respectively;

[0042] a latch structure 70 positioned vertically within the sill base 80; and

[0043] The third barrel 50 is sheathed on the loc...

Embodiment 2

[0049] This embodiment discloses a soundproof door, which includes a door panel 10 and the sill structure in Embodiment 1. A sealing strip is arranged between the door panel and the threshold structure. Compared with the existing sound insulation door without threshold, the sound insulation door has better sound insulation effect, and by setting the lifting threshold assembly, it has convenience on the basis of better sound insulation effect, and is convenient for hungry products, vehicles and personnel in and out.

Embodiment 3

[0051] This embodiment discloses a sound insulation method, comprising the following steps:

[0052] S1, setting the sill structure: set a sill structure described in Embodiment 1 on the underside of the door panel;

[0053] S2. Pop-up of the lifting threshold assembly: before the door panel is closed, the lifting threshold assembly is pressed down forcefully. At this time, through the coil spring, the second cylinder lifts up the first cylinder, giving the lifting threshold assembly a rapid upward impact and pushing The turn buckle rotates, the turn buckle turns back into the third cylinder, and the lifting threshold assembly pops up;

[0054] S3. Door panel closing: when the door panel is closed, the lifting threshold assembly fits closely with the groove on the lower part of the door panel to achieve sound insulation.

Abstract

The invention relates to the field of acoustics, in particular to a threshold structure. According to the lifting hidden-type threshold structure, a threshold lifting assembly is arranged to enable the threshold structure to be flush with the ground when a door plate is opened, and in-out of products, vehicles and personnel is facilitated accordingly. After the threshold lifting assembly bounces,the door plate is closed, the threshold lifting assembly and a rabbet in the lower portion of the door plate are tightly matched, and sealing between the door plate and the high-sound-insulation threshold structure is achieved. Compared with an existing sound-insulation door without a threshold, the sound insulation effect is better, additionally, the lifting hidden-type threshold structure has the advantages that the structure is exquisite, sealing is good, and maintenance is avoided.

Description

technical field [0001] The invention relates to the field of acoustics, in particular to a threshold structure. Background technique [0002] At present, when creating an ultra-quiet acoustic experiment environment, sound insulation doors with large sound insulation are used, and the sound insulation effect of the sound insulation door depends critically on the sealing performance between the sound insulation door and the door frame (the door panel itself The sound insulation can easily achieve 40dB, or even greater). In many cases, in order to facilitate the entry and exit of equipment, vehicles and personnel, the threshold has to be canceled when designing the sound insulation door, which will have a great adverse effect on the overall sound insulation of the sound insulation door. At present, for soundproof doors without a threshold, the gap between the door and the ground is usually sealed with a sealing strip to block the noise. However, the sound insulation of the sea...
