Description

Technical Field

[0001] The present invention relates to the technical field of invisible inspection doors, and in particular to an invisible inspection door. Background Art

[0002] Inspection doors are an important part of interior decoration. Inspection doors are devices that need to be inspected during the decoration process, such as electrical conduit pipes, toilet and kitchen water supply and drainage pipes, etc. They are widely used in government departments, airports, star-rated hotels, guesthouses, office buildings, residential buildings, villas, shops and other office and home places.

[0003] When a traditional inspection door is closed, the door lock and hinges are visible, and the gaps around the door leaf are inconsistent with the gaps between the tiles, making it easy to tell at a glance that there is an inspection door. This destroys the consistency with the main body and reduces the aesthetics. CN214835848U discloses a hidden hardware inspection door that uses a push-and-rebound mechanism to open the door panel. The door panel can rotate freely when opened, and tiles can be attached to the door panel. The door panel has a good invisible effect and looks more beautiful. However, such existing inspection doors have many problems: the inspection door has a complex structure and requires multiple sets of baffles, sleeve rods, shafts, connecting rods, and hooks and buckles to cooperate with each other to open and close the door panel, making it expensive, bulky, and inconvenient to use. At the same time, since the wall panel can rotate freely after opening, when the maintenance personnel accidentally use excessive force to open the wall panel, the door panel is likely to hit the wall panel in the opposite direction, which can easily cause scratches or damage to the wall panel or the tiles on the wall panel, affecting the overall use. Therefore, it is urgent for those skilled in the art to design a new type of hidden inspection door. Summary of the Invention

[0004] The problem to be solved by the present invention is that a door panel can be opened and closed by using only a single set of locking components. The structure is simple and reasonable, the cost is low, and it is relatively light to use. The travel limit part can limit the door leaf body, so that the door leaf body will be subjected to the reverse tensile force of the travel limit part after it is opened to a certain distance, so that the door panel will not hit the wall panel in the opposite direction, and will not cause scratches or damage to the wall panel or the tiles of the wall panel, thereby effectively ensuring the overall use of the invisible inspection door.

[0005] In order to solve the above problems, the present invention provides an invisible inspection door, including a wall panel and a door leaf main body movably connected to the wall panel, the wall panel is a multi-layer structure, including a wall panel reinforcement layer arranged in the middle and wall panel protective layers respectively arranged at both ends, the wall panel reinforcement layer is a hollow structure, a locking component is provided at the connection between the wall panel reinforcement layer and one end of the door leaf main body, the wall panel reinforcement layer and the door leaf main body are locked and connected by the locking component, and a travel limit part is provided at the connection between the wall panel reinforcement layer and the other end of the door leaf main body.

[0006] Preferably, the upper and lower ends of the door leaf body are movably connected to the wall panel reinforcement layer through positioning pins, thereby effectively ensuring the fixity of the upper and lower sides of the other end of the door leaf body and facilitating the rotation of the other end of the door leaf body.

[0007] Preferably, the locking component includes a locking portion and a locking groove portion locked with the locking portion.

[0008] Preferably, a first fixing member and a second fixing member are fixed to the side ends of the wall panel reinforcement layer and the inner side of the door leaf body respectively, and the first fixing member and the second fixing member serve to fix the locking portion and the locking groove portion.

[0009] Preferably, the locking portion includes a limit lock block, which is fixed to the first fixing member by a bolt, and a positioning lock is sleeved on the front end of the limit lock block. The limit lock block and the positioning lock are movably connected through a pin shaft, and a limit spring is sleeved on the pin shaft. The end of the limit spring away from the pin shaft is buckled with the inner end of the limit lock block, and a pressing pulley is movably hinged on the front end of the positioning lock buckle. The limit spring limits the rotation of the pin shaft, effectively ensuring the rotation angle of the pin shaft, thereby effectively controlling the rotation range of the positioning lock buckle.

[0010] Preferably, the lock slot portion includes a lock slot fixing section, the lock slot fixing section is fixedly connected to the second fixing member, a yielding lock slot section is fixed at the front end of the lock slot fixing section, and the pressing pulley is clamped in the yielding lock slot section, thereby effectively ensuring the opening and closing of the lock slot portion and the lock buckle portion.

[0011] Preferably, the travel limiting portion comprises a spring telescopic tube, and both ends of the spring telescopic tube are respectively connected to the door leaf body and the wall panel reinforcement layer.

[0012] Preferably, rivet nuts are fixedly provided on the door leaf main body and the wall panel reinforcement layer, the spring telescopic tube is sleeved in the rivet nut, and the screw is sleeved in the rivet nut to fix the spring telescopic tube.

[0013] Preferably, the wall panel protective layer is made of ceramic tiles.

[0014] The above structure has the following beneficial effects:

[0015] The wall panel reinforcement layer of the present invention has a hollow structure, and a locking component is provided at the connection between the wall panel reinforcement layer and one end of the door leaf main body. The wall panel reinforcement layer and the door leaf main body are locked and connected by the locking component. Only a single set of locking components is needed to realize the opening and closing of the door panel. The structure is simple and reasonable, the cost is low, and it is relatively light to use.

[0016] A travel limiter is provided at the connection between the wall panel reinforcement layer and the other end of the door leaf body of the present invention. The travel limiter can limit the door leaf body so that the door leaf body will be subjected to the reverse tensile force of the travel limiter after it is opened to a certain distance, so that the door panel will not hit the wall panel in the opposite direction, and will not cause scratches or damage to the wall panel or the tiles of the wall panel, thereby effectively ensuring the overall use.

Implementation Method

[0023] The present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 5 As shown, an invisible inspection door includes a wall panel 1 and a door leaf main body 2 movably connected to the wall panel 1. The wall panel 1 is a multi-layer structure, including a wall panel reinforcement layer 11 arranged in the middle and a wall panel protective layer 12 respectively arranged at both ends. The wall panel protective layer 12 is made of ceramic tiles. The wall panel reinforcement layer 11 is a hollow structure. A locking component 3 is provided at the connection between the wall panel reinforcement layer 11 and one end of the door leaf main body 2. The wall panel reinforcement layer 11 and the door leaf main body 2 are locked and connected by the locking component 3. A travel limit part 4 is provided at the connection between the wall panel reinforcement layer 11 and the other end of the door leaf main body 2.

[0025] like Figure 3As shown, the upper and lower ends of the door leaf body 2 are movably connected to the wall panel reinforcement layer 11 through the positioning pin shaft 7, thereby effectively ensuring the fixity of the upper and lower sides of the other end of the door leaf body 2 and facilitating the rotation of the other end of the door leaf body 2.

[0026] like Figure 2 As shown, the locking component 3 includes a locking portion 31 and a locking groove portion 32 locked with the locking portion.

[0027] A first fixing member 5 and a second fixing member 6 are fixed to the side ends of the wall panel reinforcement layer 11 and the inner side of the door leaf body 2 respectively. The first fixing member 5 and the second fixing member 6 play the role of fixing the locking portion 31 and the locking groove portion 32.

[0028] The locking portion 31 includes a limiting lock block 33, which is fixed to the first fixing member 5 by bolts, and a positioning lock buckle 34 is sleeved on the front end of the limiting lock block 33. The limiting lock block 33 and the positioning lock buckle 34 are movably connected through a pin shaft, and a limiting spring is sleeved on the pin shaft. The end of the limiting spring away from the pin shaft is buckled with the inner end of the limiting lock block 33, and a pressing pulley 35 is movably hinged at the front end of the positioning lock buckle 34. The limiting spring limits the rotation of the pin shaft, effectively ensuring the rotation angle of the pin shaft, thereby effectively controlling the rotation range of the positioning lock buckle 34.

[0029] The lock groove portion 32 includes a lock groove fixing section 36, which is fixedly connected to the second fixing member 6. A yield lock groove section 37 is fixed to the front end of the lock groove fixing section 36, and the pressing pulley 35 is clamped in the yield lock groove section 37, thereby effectively ensuring the opening and closing of the lock groove portion 32 and the lock buckle portion 31.

[0030] The travel limiting portion 4 includes a spring telescopic tube 41 , both ends of which are connected to the door leaf body 2 and the wall panel reinforcement layer 11 respectively.

[0031] The door leaf body 2 and the wall panel reinforcement layer 11 are both fixedly sleeved with rivet nuts 42 , the spring telescopic tube 41 is sleeved in the rivet nut 42 , and the screw 43 is sleeved in the rivet nut 42 to fix the spring telescopic tube 41 .

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0033] The specific working process is as follows: the maintenance personnel presses the wall panel protective layer 12 of the wall panel 1 and pushes the door leaf main body 2 inward, so that the locking portion 31 of the locking component 3 at the side end of the wall panel reinforcement layer 11 is close to the inner locking groove portion 32 of the door leaf main body 2, and the pressing pulley 35 of the locking portion 31 is engaged in the yielding lock groove section 37 of the locking groove portion 32 to close the door leaf main body 2. The maintenance personnel presses the wall panel protective layer 12 of the wall panel 1 and pushes the door leaf main body 2 outward, so that the pressing pulley 35 of the locking portion 31 is engaged in the yielding lock groove section 37 of the locking groove portion 32 and separates, thereby opening the door leaf main body 2. The rotation of the door leaf main body 2 drives the spring expansion tube 41 of the travel limit part 4 to stretch. When the stretching limit of the spring expansion tube 41 is reached, the door leaf main body 2 can be limited, so that the door leaf main body 2 will be subjected to the reverse tensile force of the travel limit part 4 after being opened to a certain distance.
