[0009] Preferably, the first half nozzle is a first rotating shaft that can rotate around its own axis, the second half nozzle is a second rotating shaft that can rotate around its own axis, and the first rotating shaft is arranged in parallel with the second rotating shaft.

[0010] Preferably, there is a preset gap between the first rotating shaft and the second rotating shaft, and the size of the preset gap is adjustable. An elastic member is arranged between the first rotating shaft and the second rotating shaft, and the elastic member can keep the first rotating shaft and the second rotating shaft in a tendency of elastic tension.

[0031] The core of the present invention is to provide a door slow-down structure and a door body to solve the problem that offensive noise is easily generated when the door body is closed quickly.

[0032] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] like Figure 1-Figure 12 As shown, an embodiment of the present invention provides a slow-descent structure for a door body, comprising a door stop assembly 2 and a door body 6 which can be opened and closed and is arranged on the door stop assembly 2, wherein a slow-descent lock tongue 5 is arranged on the door stop assembly 2, and a slow-descent nozzle 7 which is adapted to the slow-descent lock tongue 5 is arranged on the door body 6; or a slow-descent nozzle 7 is arranged on the door stop assembly 2, and a slow-descent lock tongue 5 which is adapted to the slow-descent nozzle 7 is arranged on the door body 6; the slow-descent lock tongue 5 is provided with a groove 8 along the extension direction of its tongue body, and when the door body 6 is opened and closed within a zero to a preset angle relative to the door stop assembly 2, the slow-descent lock tongue 5 cooperates with the slow-descent nozzle 7, and the slow-descent nozzle 7 always remains in an automatically tightened state and is clamped on the slow-descent lock tongue 5 and can slide on the slow-descent lock tongue 5.

[0034] It should be noted that those skilled in the art should be able to understand that in order to enable the slow-dropping mouthpiece to slide on the slow-dropping lock tongue, each groove on the extended surface of the tongue body of the slow-dropping lock tongue should have a smooth transition. The tongue body extension trajectory of the slow-dropping lock tongue 5 should fall on a circular trajectory with the door shaft 13 as a circle and the distance between the position where the slow-dropping mouthpiece or the slow-dropping lock tongue is installed on the door body 6 and the door shaft as a radius, so that the slow-dropping mouthpiece 7 can always fall on the circular trajectory when the door body is opened and closed within a range of zero to a preset angle.

[0035] It should also be noted that those skilled in the art should be able to understand that, generally speaking, the door body includes a door stop assembly 2 fixed on the wall 1 and a door body 6 that can be opened and closed and is arranged on the door stop assembly 2. The door stop assembly 2 includes a stand 4 fixed on the wall 1 and a door stop 3 fixed on the stand 4. The door body 6 can be opened and closed on the stand 4 by means of a hinged door shaft 13, and the door body 6 abuts against the door stop 3 when closed. When the slow-down latch is arranged on the door stop assembly, it is generally preferred to arrange the slow-down latch on the stand for more convenient arrangement; when the slow-down nozzle is arranged on the door stop assembly, it is generally preferred to arrange the slow-down nozzle on the stand for convenient arrangement.

[0036] During the actual operation of the above-mentioned slow-descent structure, when the door body is opened and closed within the range of 0° to a preset angle, the slow-descent lock tongue will cooperate with the slow-descent bayonet, and during the cooperation process, the slow-descent bayonet always remains in an automatically tightened state and is clamped on the slow-descent lock tongue and can slide on the slow-descent lock tongue. At the same time, a groove is provided in the extension direction of the tongue body of the slow-descent lock tongue. Therefore, when the slow-descent bayonet moves uphill through the groove, the slow-descent lock tongue will have a buffering and deceleration effect on the slow-descent bayonet. Therefore, when the initial closing speed of the door body is relatively large, the buffering and deceleration effect of the uphill movement of the groove on the slow-descent lock tongue causes the door body to produce a buffering and deceleration, which can greatly reduce the probability of generating offensive noise when the door body is closed quickly.

[0037] In some specific embodiments, the number of the grooves 8 is at least two, and when the door body 6 is fully closed, the slow-down clamp 7 is clamped on the groove 8 near the root of the tongue body. By arranging the number of grooves to be at least two, the slow-down clamp can be used to hover the door body when it is on a groove other than the groove near the tongue body rod. In actual application, the total number of grooves corresponding to the number of hovering positions N is N+1, and the hovering angle can be arbitrarily selected within 0°-90° according to actual needs.

[0038] In some more specific embodiments, the specific structure of the above-mentioned slow-dropping mouthpiece 7 may include a first half mouthpiece 9 and a second half mouthpiece 10 elastically clamped and tightened relative to the first half mouthpiece 9, and when the slow-dropping mouthpiece 7 cooperates with the slow-dropping lock tongue 5, the first half mouthpiece 9 and the second half mouthpiece 10 are clamped on the tongue body. Of course, it can be understood that the clamping method of the above-mentioned two half mouthpieces is only a preferred example of the slow-dropping mouthpiece in the embodiment of the present invention. In actual application, the slow-dropping mouthpiece can also be clamped on the slow-dropping lock tongue in a wrapped manner, such as a slow-dropping mouthpiece made of elastic materials such as rubber.

[0039] In a further embodiment, the first half-mouth 9 is preferably a first rotating shaft that can rotate around its own axis, and the second half-mouth 10 is preferably a second rotating shaft that can rotate around its own axis, and the first rotating shaft is arranged in parallel with the second rotating shaft. By setting the structure of the first rotating shaft and the second rotating shaft, when the first half-mouth and the second half-mouth slide relative to the slow-down lock tongue, the sliding friction is changed into rolling friction, thereby avoiding the wear of the first half-mouth, the second half-mouth and the slow-down lock tongue, and improving the service life of the slow-down structure. It should be noted that the tendency of elastic clamping between the first half-mouth and the second half-mouth can be achieved by respectively setting corresponding thrust springs or hydraulic cylinders on the first half-mouth and the second half-mouth.

[0040] Alternatively, there is a preset gap between the first rotating shaft and the second rotating shaft, and the size of the preset gap is adjustable, and an elastic member 11 is provided between the first rotating shaft and the second rotating shaft, and the elastic member 11 can keep the first rotating shaft and the second rotating shaft in an elastically tightened trend. It should be noted that the elastic member here can be a spring, or a member of other elastic materials commonly used by those skilled in the art.

[0041] In some more specific embodiments, in order to make the head of the slow-drop lock tongue 5 enter the slow-drop clamping nozzle more smoothly and facilitate guidance, the longitudinal section of the head of the slow-drop lock tongue 5 is preferably V-shaped or U-shaped. Of course, it can be understood that the above is only a preferred example of the structural form of the head of the slow-drop lock tongue. In actual application, other corresponding structural forms can also be selected according to actual needs.

[0042] In a further embodiment, the above-mentioned slow-drop lock tongue 5 is preferably made of elastic wear-resistant material. For example, the slow-drop lock tongue 5 is an integrally formed rubber part. Of course, it is understandable that the above-mentioned slow-drop lock tongue can also be made of other materials, but the present invention preferably uses elastic wear-resistant material.

[0043] In a further embodiment, in order to further reduce the impact on the door stop of the door stop assembly when the door body is closed, a damper 12 for alleviating the closing action of the door body is further provided between the door stop assembly 2 and the door body 6. This can further reduce the noise problem when the door is closed vigorously. It should be noted that the damper can be an oil damper or other types of dampers commonly used by those skilled in the art, such as a gas damper.

[0044] In addition, the present invention further provides a door body, including a slow-down structure, which is the slow-down structure described in any of the above schemes. Since the above slow-down structure has the above technical effects, the door body having the above slow-down structure should also have corresponding technical effects, which will not be repeated here.

[0045] The above is a detailed introduction to the door slow-down structure and door body provided by the present invention. It should be noted that each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other.

[0046] It should also be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that an article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such articles or devices. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the article or device including the above elements.

[0047] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
