Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. Referring to fig. 1, the utility model discloses a fire hydrant hidden door 1 structure capable of increasing the opening angle of hidden door 1. A frame 2 is fixedly connected inside the hidden door 1, the top and the bottom of one side edge of the frame 2 are respectively and pivotally provided with a second rotating shaft 4, and the two second rotating shafts 4 are respectively and pivotally connected with a third rotating shaft 5 through second rotating supports 7. During the rotation process, the second rotating shaft 4 and the third rotating shaft 5 can rotate around the second rotating bracket 7, and the rotating directions are the same when the second rotating bracket is contracted and opposite when the third rotating bracket is opened. The rotating shaft III 5 is hinged with a rotating shaft I3 through a rotating bracket I6 parallel to the hidden door 1, and the rotating shaft III 5 drives the rotating shaft I3 to rotate through the bracket in the rotating process. The first rotating shaft 3 is fixedly connected to the inner fixed frame 12 through the support 8, the support 8 is composed of two connecting plates with included angles smaller than 90 degrees, and the arrangement of the structure of the support 8 can enable the first rotating shaft 3 to be more tightly connected with the first rotating shaft, so that the impulsive force generated when the blank door 1 is closed is reduced, and the service life of the rotating shaft is prolonged.

As shown in FIG. 3, the top and bottom ends of the frame 2 are respectively provided with a stopper 9. When hidden door 1 reaches the biggest opening angle in the state that hidden door 1 opened, hidden door 1 right side can close on with the left wall body of hidden door 1, thereby stopper 9 leans on earlier with the wall body and reaches limiting displacement and avoid 1 inboard frame 2 structure of hidden door and wall body direct impact to cause the wall damaged this moment.

Referring to fig. 1 and 2, the hidden door 1 is provided with a decorative structure layer 10 and an inner frame 2 from outside to inside. The decorative structure layer 10 is fixedly connected with the frame 2, two sides of one surface of the decorative structure layer 10 facing the internal fixed frame 12 are provided with inclined limiting surfaces 101, and the wall side edges of the decorative structure layer 10 at two sides of the hidden door 1 are provided with limiting inclined surfaces 102 matched with the inclined limiting surfaces 101. The outer side of the hidden door 1 is provided with a decorative structure layer 10, which can be a single external decorative board structure or a composite structure, for example, a decorative layer and a stone surface layer are combined to form the decorative structure layer 10. When the decorative structure layer 10 is a single layered structure, the two sides of the decorative structure layer 10 are provided with the inclined limiting surfaces 101, and when the decorative structure layer is a composite structure, the two sides of the middle layer are provided with the inclined limiting surfaces 101. And a limiting inclined surface 102 matched with the inclined limiting surface 101 is arranged on the outer side wall body corresponding to the decorative structure layer 10, and the limiting inclined surface and the inclined limiting surface are matched to finish complete homing when the hidden door 1 is closed.

Referring to fig. 2, a metal separation layer 11 is disposed on the outer side surface of the blank door 1, the metal separation layer 11 divides the decorative structure layer 10 into an upper part and a lower part, and the decorative structure layers of the upper and lower structures are not on the same horizontal plane. The utility model discloses in 1 outside decorative structure layer 10 of dark door that describes not only, structural arrangement is only common surface course setting form about decorative structure layer 10, and the utility model discloses the effect that heterotypic dark door 1 can reach still sets up the form including the heterotypic of other decorative structure layer types that have arbitrary shape dark door 1 and both sides wall body. No matter what kind of form's the lateral surface structure of hidden door 1 or the heterotypic form that sets up of both sides wall body can both pass through the utility model discloses a structural design accomplishes the wide-angle of hidden door 1 and opens. The support 8, the first rotating support 6 and the second rotating support 7 are galvanized square pipe supports, and the limiting block 9 is made of elastic materials. In order to protect the safety of the adjacent wall bodies, the limiting blocks 9 are arranged on the two sides of the frame 2 due to the fact that the opening and closing force of the hidden door 1 is avoided to be too large, the limiting blocks 9 are made of flexible materials and can buffer the impact force of the adjacent wall bodies, and the service lives of the hidden door 1 and the wall bodies are prolonged.

The working process of the utility model is combined with the figures 1 to 3. When the special-shaped fire hydrant hidden door 1 needs to be opened for maintenance or use, the bright handle or the hidden handle on the hidden door 1 can be pulled by hand to enable the hidden door 1 to move outwards along the horizontal direction. At the moment, the first rotating support 6 begins to incline and drives the third rotating shaft 5 to contract towards the left side, and in the process, the second rotating support 7 is influenced by the third rotating shaft 5 and inclines towards the first rotating shaft 3 at the same time so as to supplement the displacement distance required by the horizontal outward movement of the hidden door 1 and avoid the possibility that the right side position is blocked when the hidden door 1 directly rotates. When the hidden door 1 finishes horizontal transverse movement and is far away from the wall surface, the hidden door 1 is pushed to integrally move to one side, and at the moment, the first rotating shaft, the second rotating shaft and the third rotating shaft cannot have any limitation until the hidden door 1 completely finishes the pulling action. After the hidden door 1 is completely opened, the close state is completed by the limiting block 9 and the wall body, and the opening process is finished.

When the hidden door is closed, the hidden door 1 only needs to be pushed to move towards the position of the door frame, the second rotating shaft 4 drives the third rotating shaft 5 to transmit to the first rotating shaft 3 to realize the linkage effect, and the gradual folding and returning process of the hidden door 1 is completed. When the hidden door 1 is opposite to the door frame, the hidden door 1 is horizontally pushed to move inwards until the hidden door 1 is embedded into the wall, at the moment, the closing is finally completed through the matching of the inclined limiting surface 101 and the limiting inclined surface 102, and the closing process of the hidden door 1 is finished.

In the above embodiment, the installation position of each support structure is not unique, and specifically, the installation is performed adaptively according to the weight of the blank door 1 and the load bearing requirement, and the first rotating shaft 3, the second rotating shaft 4, the third rotating shaft 5, the support 8, the first rotating support 6 and the second rotating support 7 in the technical scheme are two or more and are matched with each other to form a group. The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.

This embodiment is the preferred embodiment of the present invention, not limiting the protection scope of the present invention according to this, so: all equivalent changes made according to the knot, shape and principle of the utility model should be covered within the protection scope of the utility model.
