[0002] With the promotion of civilized sacrifices and the development of science and technology, a new way of sacrifice is gradually being promoted: the plaques that record the life information of the deceased are usually stored in a special storehouse in the temple, also known as a storage room. On festival days, they are taken out and placed in the corresponding hall for relatives and friends to worship, and then put back into the storehouse for storage after the sacrifice.
[0003] The prior art already has a Fu brand database management system. When specific information is input into the system input terminal, the Fu brand database management system will send the required Fu brand to the door of the storage room, and the brand can be taken out after the door is opened.
[0004] The doors of the prior art are generally opened and closed by rotating or pulling left and right; the outer surface of the door before opening and after closing is not flush with the outer surface of the wall surrounding the door opening; the flexibility and stability of the door opening and closing process are still lacking, and improvement is urgently needed. Utility Model Content
[0005] The utility model aims to solve the technical problem of providing an electric door device for a sacrificial blessing tablet storage room, which opens upward and closes downward and the door is flush with the outer surface of the wall around the door opening before and after opening.
[0006] The technical solution of the utility model is to provide an electric door device for a storage room for sacrificial blessing tablets, including a motor fixed on the inner wall of a wall on one side of a door opening, a rack driven to rise and fall by the motor, a first connecting block connected to the rack and the inner wall of the door slidingly matched on a vertical guide rail fixed on the inner wall of a wall on one side of the door opening, and the edges of the inner wall of the door and the inner walls of the walls on both sides of the door opening have a linear lifting guide and an inner and outer sliding structure, which enables the door to slide inwards and rise straightly when opened, and to descend straightly and slide outwards when closed, and enables the outer wall of the door to be flush with the outer wall of the wall surrounding the door opening.
[0007] After adopting the above structure, the electric door device of the sacrificial blessing tablet storage room of the utility model has the following advantages:
[0008] When the door is opened, the motor drives the rack to rise and drives the door to slide inward and rise straightly through the first connecting block. Since the outer wall of the door is flush with the outer wall of the wall surrounding the door opening, there are generally overall murals on the outer wall of the door and the outer wall of the wall surrounding the door opening that match the atmosphere at the time. When the motor receives the start signal, it suddenly opens a door upward from the mural, and family members and friends see the deceased's blessing plaque, such as a blessing plaque with a carved frame base. In addition, after adopting the above door opening structure, the flexibility and stability of the door opening straight inward and upward are good. When it is straight downward and then closed inward, it also has the above-mentioned technical effects.
[0009] Furthermore, the linear lifting guide and internal and external sliding structure include: two vertical strips fixed on the edges of the inner wall of the two sides of the door opening, the two vertical strips are symmetrically provided with respective vertical guide grooves on the opposite sides, and the bottom of each vertical guide groove is an arc-shaped groove with a lower inner side and a higher outer side; the rollers rolling in the respective vertical guide grooves are fixed to the second connecting block fixed to the inner wall of the door through their respective roller shafts; there is a guiding inclined surface with a thin bottom and a thick top on the inner wall of the top wall of the door opening; each internal and external sliding structure is a structure that slides inward and outward with upper and lower limits, and the first connecting block is connected to the inner wall of the door through an upper and lower limit and an internal and external sliding structure. After the internal and external sliding adopts the above specific structure, the flexibility and stability of the door opening process from inward to straight upward are better, and the process of opening the door can better set off the above-mentioned atmosphere, giving family members and friends a better psychological feeling.
[0010] Furthermore, each structure of the upper and lower limit and inner and outer sliding is as follows: a transverse guide rail fixed to a third connecting block fixed to the inner wall of the door is provided with respective first transverse sliding grooves and first transverse sliding blocks on the upper and lower sides, and a first sliding seat fixed to the first connecting block has second transverse sliding blocks and second transverse sliding grooves on the upper and lower sides that are slidably matched with the first transverse sliding grooves and first transverse sliding blocks on the upper and lower sides. After the upper and lower limit and inner and outer sliding adopt the above specific structure, there is no need to add additional internal and external drive cylinders and other drivers, which saves both the device cost and the use cost, and the coordination and cooperation of the inner and outer sliding and the straight rise and fall are flexible, smooth and stable.
[0011] Furthermore, the two sides of the vertical guide rail are provided with respective first vertical slide grooves and first vertical sliders, and the second sliding seat of the first connecting block is provided with two second vertical sliders and two second vertical slide grooves that embrace the two first vertical slide grooves and the two first vertical sliders; the second sliding seat is fixed to one side of a vertical U-shaped plate, the opening of the vertical U-shaped plate is covered on a vertical strip plate, and the other side of the vertical U-shaped plate is fixed to the first sliding seat. After adopting the above specific structure, the straight-line up and down sliding of the door is more flexible and more stable, and the setting of the vertical U-shaped plate makes the inner and outer sliding of the door and the straight-line up and down not interfere with each other and cooperate and coordinate with each other, and the opening and closing process is smoother and more stable.
[0012] Furthermore, the first connecting block is two pieces, and the first connecting block is connected to the inner wall of the door through an upper and lower limiter and the structure of sliding inward and outward is two sets, one set is located at the upper part of one side of the inner wall of the door, and the other set is located at the lower part of one side of the inner wall of the door. After adopting the above structure, the upper and lower sets simultaneously connect the door and the rack, making the linear up and down sliding of the door more flexible and more stable, making the opening and closing process of the door smoother and more stable.
[0013] Furthermore, each vertical strip plate has two vertical guide grooves, one on the outside and one on the inside, and the two vertical guide grooves on the same height section of each vertical strip plate are partially parallel; the rollers on each side that roll in their respective vertical guide grooves are fixed to the second connecting block fixed to the inner wall of the door through their respective roller shafts, and the structure is composed of two sets: the upper second connecting block is connected to the upper vertical guide groove, and the lower second connecting block is connected to the lower vertical guide groove. After the above two sets of structures are adopted for the internal and external sliding and the linear up and down guiding of the door, the internal and external guiding and the up and down linear guiding are smoother, smoother, more flexible and more stable.
[0014] Furthermore, the upper sleeve of the upper and lower sleeves is arranged in the middle of both sides of the inner wall of the door, and the lower sleeve is arranged at the bottom of both sides of the inner wall of the door, and the length of the second connecting block in the middle from the inner wall of the door to the outside is longer than the length of the second connecting block at the bottom from the inner wall of the door to the outside. After adopting the above structure, the second connecting block of the guide structure and the first connecting block driven by the rack to lift the door are staggered in height, so that the door can slide in and out and lift straightly more smoothly, more smoothly, more flexibly and more steadily.
[0015] Furthermore, the structure of the rack driven by the motor is as follows: the top of the vertical motor is connected to a reduction box, which is fixed to the inner wall of the wall on one side of the door opening through a fixed seat, and the output shaft of the reduction box has a horizontal active bevel gear, and the vertical passive bevel gear meshing with the active bevel gear is coaxially fixed with a cylindrical gear, and the shaft is rotatably matched with a bearing seat fixed to the inner wall of the wall on one side of the door opening through a rolling bearing, and the cylindrical gear is meshed with the rack. After adopting the above structure, the connection between the door drive mechanism and the transmission mechanism is more compact, the occupied area is smaller, the driving force is strong, and the working reliability is good.
[0016] Furthermore, a linear conveying device is provided on the bottom surface of the storage chamber inside the door for conveying the blessing tablet with a base to the door opening in a linear manner. The track of the linear conveying device is 90 degrees with the door and the outer end is fixed to the bottom frame rod below the door opening.
