The specific embodiment is as follows:
the utility model will be further described with reference to specific examples and figures.
The utility model discloses a horizontal split cover for a showcase of a museum, which is shown in fig. 1 to 5, and is used for facilities for displaying cultural relics, valuables in places such as the museum, the cultural relics and the like. The showcase comprises: the showcase body 1 and the horizontal split cover covered on the showcase body 1.
The showcase main body 1 adopts a steel frame or an aluminum alloy framework, and a boss 10 is formed on the upper surface of the showcase main body. The boss 10 is used for displaying articles such as cultural relics. A carrying floor 100 is formed around the outside of the boss 10, the carrying floor 100 being used for the placement of a horizontal split cover.
The horizontal split cover is arranged above the showcase main body 1, covers the boss 10 in a closed state and comprises two glass covers 2 which are distributed above the showcase main body 1 in a bilateral symmetry manner, the glass covers 2 are slidably arranged on the showcase main body 1, and the two glass covers 2 are driven to oppositely or reversely run through a driving device 3 arranged in the showcase main body 1 to realize the opening or closing of the two glass covers 2.
The glass cover 2 includes: a carrying seat 21 and a glass cover 22 fixed on the carrying seat 21. The bearing seat 21 is U-shaped, the bearing seat 21 is usually in a steel frame or an aluminum alloy framework, and the bearing seat 21 is in sliding connection with the showcase main body 1 through the sliding rail structure 4.
The glass cover body 22 in each glass cover 2 comprises four glass panels which are combined, the glass covers 2 on the left side and the right side are oppositely arranged, and the two glass cover bodies 22 form a cuboid cover in a folding state. The glass cover 22 can be made of an explosion-proof toughened glass plate with the thickness of 8-12 mm.
The driving device 3 includes: a motor 31, a driving shaft 32 linked with the motor 31, a left screw 33 and a right screw 34. One end of the outer side of the left screw rod 33 is connected with the bearing seat 21 positioned on the left glass cover 2, and one end of the outer side of the right screw rod 34 is connected with the bearing seat 21 positioned on the right glass cover 2.
In order to achieve a folding of the left and right glass panes 2 when driven by the drive 3, a folding of the relative movement and a folding of the opposite movement can be achieved. The screw thread directions on the left screw rod 33 and the right screw rod 34 are opposite, the left screw rod 33 and the right screw rod 34 are both interlocked with the driving shaft 32, the left screw rod 33 and the right screw rod 34 are driven to simultaneously operate through the motor 31, and the bearing seats 21 on the left side and the right side are respectively pushed to move along the sliding rail structure 4, so that the horizontal opening and closing of the cover are realized.
Specifically, two ends of the driving shaft 32 in the driving device 3 are respectively provided with a left gear 321 and a right gear 322, and a left screw sleeve 35 respectively matched with the left screw 33 and a right screw sleeve 36 matched with the right screw 34 are positioned in the showcase main body 1; the outer ring of the left screw rod sleeve 35 is provided with a left gear ring 351 meshed with the left gear 321, and the outer ring of the right screw rod sleeve 36 is provided with a right gear ring 361 meshed with the right gear 322.
The left screw rod sleeve 35 and the right screw rod sleeve 36 are respectively positioned and installed in the showcase main body 1 through bearing blocks 37. Screw holes matched with the left screw rod and the right screw rod are formed in the left screw rod sleeve and the right screw rod sleeve. Taking the left screw sleeve 35 as an example: when the left gear 321 drives the left gear ring 351 meshed with the left gear 321 to rotate, the whole left screw rod sleeve 35 starts to rotate, and the left screw rod sleeve 35 cannot translate left and right due to the fact that the left screw rod sleeve 35 is positioned through the bearing seat 37, at the moment, the left screw rod 33 is driven by screw threads to move horizontally, and accordingly the left glass cover is driven to operate.
In order to increase the anti-theft effect, the motor 31 is linked with the driving shaft 32 through a worm and gear mechanism. Specifically, the turbine worm mechanism includes: a worm 38 coupled to an output shaft of the motor 31, and a worm wheel 39 fixed to the drive shaft 32. The motor 31 drives the drive shaft 32 to rotate through a worm and gear mechanism. When the exhibition is finished, only the power supply is needed to be cut off, and the external force can not directly push the glass cover 2 to move due to the self-locking function of the worm wheel and the worm, so that the anti-theft function is realized.
The sliding rail structure 4 comprises: the roller 41 or the bearing are arranged on the front side and the rear side of the showcase main body 1 in a straight line, and the slideway 42 is formed on the inner side surfaces of the front side wall and the rear side wall of the bearing seat 21, and the bearing seat 21 is in sliding connection with the showcase main body 1 through the nesting fit of the roller 41 or the bearing and the slideway 42. Specifically, the rollers 41 are disposed on the front and rear sides of the boss 10 and above the carrying platform 100. The roller 41 is mounted on the front and rear sides of the boss 10 through a shaft 411, and the slideway 42 includes: the roller device comprises a channel 421 for accommodating the roller 41 or the bearing, and an open slot 422 formed in the inner side surface of the bearing seat 21 and communicated with the channel 421, wherein the width of the open slot 422 is smaller than that of the channel 421. The roller 41 is thus embedded in the channel 421, ensuring that it does not fall out.
In addition, the maximum displacement travel between the showcase main body 1 and each glass cover 2 is not more than half of the length of the glass cover 2, so that damage caused by overlarge displacement and self gravity moment of the glass cover 2 is avoided.
The utility model combines the advantages of showcases with doors and showcases without doors, drives the two glass covers 2 to open and close by one electric 31, facilitates the picking and placing of the exhibited articles, and further enhances the anti-theft effect by utilizing the self-locking function of the driving mechanism.
It is understood that the foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, but rather is to be accorded the full scope of all such modifications and equivalent structures, features and principles as set forth herein.
