[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a soundproof and heat-insulating anti-theft door, comprising a door body 1, a cavity being formed on the surface of the door body 1, and multiple sets of protective railings 2 being fixedly connected to the inner wall of the cavity of the door body 1. By providing protective railings 2 on the inner wall of the cavity of the door body 1, ventilation can be carried out when the cavity of the door body 1 is opened, while preventing the door body 1 from being opened from the outside. A buffer component 3 is provided on the inner wall of the door body 1.

[0031] Reference Figure 2The buffer assembly 3 includes a slider 33, which is elastically connected to the inner side wall of the door 1 via a limiting spring 32. One end of the limiting spring 32 is fixedly connected to the outer wall of the slider 33, and the other end is fixedly connected to the inner side wall of the door 1. The function of the limiting spring 32 is that when the door 1 is closed, the contact frame 35 will cause the airtight door seal 36 to contact the door frame first. This allows the contact frame 35 to push the slider 33 to move mechanically on the surface of the guide rod 31 via the outer hinge rod 34, and the limiting spring 32 will be elastically compressed. Thus, the limiting spring 32 buffers the impact force when the airtight door seal 36 contacts the door frame. The inner wall of the slider 33 is slidably connected to the guide rod 31. The guide rod 31 guides the slider 33 to move only in a straight line, and the guide rod 31 is fixedly connected to the inner side wall of the door body 1. The slider 33 is slidably connected to the inner side wall of the door body 1. The outer wall of the slider 33 is hinged to a hinge rod 34. The end of the hinge rod 34 away from the slider 33 is hinged to a contact frame 35. An annular groove is opened on the surface of the door body 1. The contact frame 35 is slidably connected to the inner wall of the annular groove. An airtight door seal 36 is provided on the surface of the contact frame 35. The airtight door seal 36 is existing technology. By providing an airtight door seal 36 on the surface of the contact frame 35, the connection between the door body 1 and the door frame can be sealed when the door body 1 is closed, thereby preventing air from entering the room from the gaps. A shielding component 4 is provided on the inner wall of the door body 1.

[0032] Reference Figure 1 and Figure 3 The shielding component 4 includes a shielding plate 41, which is slidably connected to the inner wall of the door 1. By opening the shielding plate 41, the size of the cavity of the door 1 can be adjusted, thereby adjusting the ventilation effect. At the same time, the shielding plate 41 is equipped with sound insulation cotton, which can block some sound from entering the room through the shielding plate 41. The insert rod 43 passes through and is slidably connected to the inner wall of the bottom end of the shielding plate 41. The inner wall of the bottom end of the shielding plate 41 is elastically connected to the insert rod 43 by a return spring 42. One end of the return spring 42 is fixedly connected to the surface of the insert rod 43, and the other end of the return spring 42 is fixedly connected to the inner wall of the bottom end of the shielding plate 41. The function of the return spring 42 is to automatically reset the position of the insert rod 43 after it is pulled outward. The inner wall of the door 1 has multiple sets of through holes. The outer wall of the bottom end of the insert rod 43 is inserted into the inner wall of the through hole. The insertion between the two fixes the shielding plate 41 in multiple positions inside the door 1 to adjust the size of the cavity.

[0033] Working principle: When the door 1 is closed, the contact frame 35 drives the airtight door seal 36 to contact the door frame first. At this time, the contact frame 35 will push the slider 33 to move on the surface of the guide rod 31 through the outer hinge rod 34, so that the limit spring 32 is elastically compressed. The limit spring 32 buffers the impact force when the airtight door seal 36 and the contact frame 35 contact the door frame. At the same time, the airtight door seal 36 seals the connection between the door 1 and the door frame when the door is closed, preventing air from entering the room from the gap.

[0034] By opening the baffle plate 41, the size of the cavity of the door body 1 can be adjusted, thereby adjusting the ventilation effect. When it is necessary to adjust the position of the baffle plate 41, pull the plug rod 43 outward to separate the outer wall of the bottom end of the plug rod 43 from the through hole of the inner wall of the door body 1. After moving the baffle plate 41 to the appropriate position, release the plug rod 43. The plug rod 43 will automatically return to its original position under the action of the return spring 42, so that the outer wall of its bottom end can be inserted into the through hole at the corresponding position of the inner wall of the door body 1, thus fixing the baffle plate 41 in multiple positions inside the door body 1 to adjust the size of the cavity.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
