[0031] In a specific embodiment, Figures 1 to 5 As shown, the bidirectional draw-out bottom drawer mechanism of the cultural relic cabinet of the present invention is arranged below the main body 1 of the cultural relic cabinet used as a corridor partition, and includes a bottom drawer 2, a base 3 and a guide assembly. The base 3 is a rectangular plate seat component and is larger than the bottom area of ​​the main body 1 of the cultural relic cabinet. The base 3 is arranged at the bottom of the main body 1 of the cultural relic cabinet and is in contact with the ground of the placement place, that is, the base 3 supports the weight of the main body 1 of the cultural relic cabinet. The guide assembly is arranged between the base 3 and the bottom drawer 2, and both ends of the guide assembly protrude from the two side walls of the main body 1 of the cultural relic cabinet. The bottom drawer 2 used to carry heavy cultural relics is located between the vertical walls at the bottom of the main body 1 of the cultural relic cabinet, and the horizontally arranged bottom drawer 2 can slide back and forth along the guide assembly.

[0032] It should be noted that as long as the main body 1 of the cultural relic cabinet is not placed against a wall and there is space on both sides, the two-way drawer bottom plate mechanism of the present invention can be set, and the main body 1 of the cultural relic cabinet does not necessarily have to be used as a partition. The description here shall not be regarded as limiting the scope of protection of the present invention.

[0033] By setting the base 3 below the main body 1 of the cultural relic cabinet, on the one hand, the contact area with the ground of the placement place is increased, and the bearing capacity of the main body 1 of the cultural relic cabinet is improved; on the other hand, it is convenient to set the guide assembly on the base 3. When heavy cultural relics are placed on the bottom drawer 2, they are supported by the guide assembly at the bottom. Compared with the traditional side wall slide rail method, the support strength is large, stable and reliable, and the service life is long. The two-way pull-out bottom drawer mechanism of the cultural relic cabinet of the present invention sets the guide assembly on the base, and the bottom drawer for placing cultural relics can be pulled out in two directions on both sides. The structural strength is large and it is convenient for people to watch.

[0034] In a specific embodiment of the present invention, Figure 1 and Figures 3 to 5 As shown, the base 3 includes a base plate 301 and a seat panel 302 arranged horizontally and parallel to each other, the seat panel 302 is on the upper side and the base plate 301 is on the lower side. A plurality of vertical ribs arranged at intervals are arranged on the base plate 301. The seat panel 302 is fixedly connected to the vertical ribs by plug welding. The four sides of the seat panel 302 are bent downward and the edges of the base plate 301 are fully covered and welded together.

[0035] Specifically, the seat panel 302 is provided with a long hole for making way at the vertical wall of the main body 1 of the cultural relics cabinet, and the bottom surface of the vertical wall of the main body 1 of the cultural relics cabinet directly contacts the upper surface of the base plate 301 .

[0036] The vertical rib plate is arranged between the base plate 301 and the seat panel 302 to form a sandwich layer, which facilitates the hidden installation of the guide assembly.

[0037] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the guide assembly includes a linear guide rail 4 and a ball slider 5. Two guide rail grooves 303 are parallelly provided on the base 3. A linear guide rail 4 is installed in each guide rail groove 303. The length direction of the linear guide rail 4 is perpendicular to the large side wall of the main body 1 of the cultural relic cabinet. The linear guide rail 4 is bolted to the bottom pad, and the bottom pad is welded on the upper surface of the base plate 301. The ball slider 5 is fixed on the bottom surface of the bottom drawer plate 2, and the ball slider 5 guides and slides to connect the linear guide rail 4. The ball slider 5 is installed on the bottom surface of the bottom drawer plate 2 through a long strip of slider mounting plate 201. The cross section of the slider mounting plate 201 is a C-shaped structure with the opening facing upward.

[0038] By using the linear guide rail 4 and the ball slider 5 as the guide assembly, the friction resistance of the two-way pulling of the bottom draw plate 2 is reduced, and the bottom draw plate 2 is stable and has a strong support strength. The linear guide rail 4 and the bottom pad press and support the base plate 301 to prevent the base plate 301 from bending and deforming upward.

[0039] In a specific embodiment of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, handle bars 203 are provided on both sides of the top surface of the bottom drawer 2, and hand grip grooves are also centrally provided on the front and rear side walls of the bottom drawer 2. A seismic isolation platform can also be placed on the top surface of the bottom drawer 2 before placing heavy cultural relics, such as ceramics or metal cultural relics.

[0040] In a specific embodiment of the present invention, Figures 1 to 3 As shown, the bidirectional drawable bottom drawer mechanism of the cultural relic cabinet of the present invention further includes a center positioning component, and the center positioning component includes an electromagnet 6. The base 3 is provided with a first positioning hole 304 at the middle position between the vertical walls at the bottom of the main body 1 of the cultural relic cabinet. The electromagnet 6 is vertically installed in the first positioning hole 304, and the extreme end of the electromagnet 6 protrudes from the top surface of the first positioning hole 304. A positioning block 202 is fixedly installed at the middle position of the bottom surface of the bottom drawer 2, and the positioning block 202 is made of iron and can be adsorbed to the top surface of the extreme end of the electromagnet 6.

[0041] Specifically, if Figure 2 and Figure 3 As shown, the positioning block 202 is configured as a cylindrical wire brush disposed downward, and the wire length of the wire brush is greater than the distance between the wire installation bottom surface of the positioning block 202 and the top surface of the extreme end portion of the electromagnet 6.

[0042] Specifically, if Figure 1 and Figure 3As shown, the bidirectional drawer bottom plate mechanism of the cultural relic cabinet of the present invention further comprises a button panel 7. The two button panels 7 are respectively arranged on the front and rear side walls of the vertical wall of the cultural relic cabinet body 1. The button panels 7 control the operation of the electromagnet 6.

[0043] By adding an electromagnet 6 in the first positioning hole 304, the positioning block 202 is set in the middle position of the bottom surface of the bottom draw plate 2. In the normal collection state, the bottom draw plate 2 is locked in the frame of the main body 1 of the cultural relics cabinet, and the cultural relics are protected all around. Only after pressing the corresponding unlocking button on the button panel 7, the electromagnet 6 loses power, and the bottom draw plate 2 can be pulled outward along the linear guide 4. By setting the wire length of the wire brush to be slightly larger than the spacing, it can be ensured that when the electromagnet 6 sucks the wire brush tightly, the wire of the bottom draw plate 2 moves slightly forward and backward, and only bends and deforms, and does not separate from the electromagnet 6, which can buffer the transverse wave vibration along the linear guide 4 in the event of an earthquake.

[0044] In a specific embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the bidirectional pull-out bottom drawer mechanism of the cultural relics cabinet of the present invention also includes an external limit assembly. The base 3 has a second positioning hole 305 on the front and rear sides of the cultural relics cabinet body 1 respectively. The external limit assembly is arranged in the second positioning hole 305. The external limit assembly can block and limit the positioning block 202.

[0045] Specifically, if Figure 4 and Figure 5 As shown, the external limit assembly includes a first acting cylinder 8, which is vertically installed in the second positioning hole 305. The upward piston rod end of the first acting cylinder 8 is installed with an inclined stopper 801. The inward inclined surface of the inclined stopper 801 can block the wire brush. The electric control valve of the first acting cylinder 8 is electrically connected to the button panel 7.

[0046] By setting the outer limit assembly on the front and rear sides of the base 3, the bottom draw plate 2 can be limited to avoid overshoot and inertial collision; the oblique block 801 blocks the wire brush with an inwardly inclined surface, and the contact process is flexible, and the wire brush is bent and deformed to buffer the inertial impact force of the outward movement, avoiding the impact and collision of the cultural relics. At the same time, the squeezed and deformed wire brush can also lock the position of the bottom draw plate 2 to prevent the bottom draw plate 2 from turning back after the inertia is blocked. The oblique block 801 is installed on the upward piston rod end of the first acting cylinder 8, so that the oblique block 801 can be hidden when not in use to prevent the oblique block 801 from being stepped on.

[0047] In a specific embodiment of the present invention, Figure 1 , Figure 4 and Figure 5As shown, the outer limit assembly also includes a cover plate 9 and a second cylinder 10. The axis of the second cylinder 10 is parallel to the guide assembly. The second cylinder 10 is arranged in the base 3, that is, it is installed below the seat panel 302 through a support plate. The second cylinder 10 is located on one side of the second positioning hole 305. The piston rod of the second cylinder 10 is connected to the mounting block at the rear end of the cover plate 9 and can drive the cover plate 9 to reciprocate linearly. The cover plate 9 can completely block or completely clear the second positioning hole 305 at the bottom.

[0048] Specifically, if Figure 4 and Figure 5 As shown, a covering guide frame 901 is provided on both sides of the covering plate 9. The covering guide frame 901 has an L-shaped cross section and the top is fixedly connected to the bottom surface of the seat panel 302 of the base 3. The electric control valve of the second acting cylinder 10 is electrically connected to the button panel 7.

[0049] Obviously, the first working cylinder 8 and the second working cylinder 10 can be hydraulic cylinders, air cylinders, or even electric push rods, which can achieve similar effects. Simple replacement methods fall within the protection scope of the present invention.

[0050] The second positioning hole 305 can be electrically closed by adding the cover plate 9 and the second cylinder 10 to prevent debris from falling into the hole. The cover guide frame 901 is provided to ensure that the cover plate 9 has sufficient support strength.

[0051] In a specific embodiment of the present invention, the first working cylinder 8 and the electromagnet 6 are electrically interlocked in electrical control. That is, the electromagnet 6 can be powered to generate suction to position the bottom drawer plate 2 only when the first working cylinder 8 is in the retracted state.

[0052] The working principle of the two-way pull-out bottom drawer mechanism of the cultural relic cabinet of the present invention is as follows: when the bottom drawer 2 needs to be pulled out from any side for viewing cultural relics, the operator presses the unlocking button on the button panel 7, and the second action cylinder 10 is activated to pull the cover plate 9 backward, and the cover plate 9 opens the top of the second positioning hole 305. After a delay of two seconds, the first action cylinder 8 is pushed upward, and the oblique block 801 protrudes from the second positioning hole 305 and enters the working state. At the same time, the electromagnet 6 loses power, and the operator pulls the handle 203 or the hand-grip groove by hand to pull the bottom drawer 2 out along the linear guide 4, and the extreme end of the electromagnet 6 is separated from the wire brush of the positioning block 202. During the outward movement of the bottom drawer 2, the bottom end of the wire brush collides with the inner inclined surface of the oblique block 801, and the wire brush is squeezed and bent, which buffers the inertial impact force and protects the cultural relics. After watching, push the bottom drawer plate 2 back, press the lock button on the button panel 7, the first action cylinder 8 retreats downward, and the oblique block 801 retreats as a whole into the second positioning hole 305. After a delay of two seconds, the second action cylinder 10 acts to push the cover plate 9 forward, and the cover plate 9 closes the top of the second positioning hole 305. At the same time, the electromagnet 6 is energized, and the wire brush at the bottom of the bottom drawer plate 2 moving inward is adsorbed on the extreme end of the electromagnet 6, completing the centering positioning and locking.

[0053] In summary, the bidirectional draw-out bottom draw-out plate mechanism of the cultural relic cabinet of the present invention increases the contact area with the ground of the place of placement and improves the bearing capacity of the cultural relic cabinet body 1 by setting the base 3 below the main body 1 of the cultural relic cabinet, on the one hand, and facilitates the setting of the guide assembly on the base 3. When heavy cultural relics are placed on the bottom draw-out plate 2, they are supported by the guide assembly at the bottom. Compared with the traditional side wall slide rail method, the support strength is large, stable and reliable, and the service life is long. The bidirectional draw-out bottom draw-out plate mechanism of the cultural relic cabinet of the present invention sets the guide assembly on the base, and the bottom draw-out plate for placing cultural relics can be pulled out bidirectionally on both sides, with high structural strength and convenient for people to watch. In addition, the vertical rib plate is arranged between the base plate 301 and the seat panel 302 to form a sandwich, which is convenient for the hidden installation of the guide assembly. By using the linear guide rail 4 and the ball slider 5 as the guide assembly, the friction resistance of the bidirectional draw-out of the bottom draw-out plate 2 is reduced, and it is stable and has a large support strength. The linear guide rail 4 and the bottom pad plate press and support the base plate 301 to prevent the base plate 301 from bending and deforming upward. By adding an electromagnet 6 in the first positioning hole 304, the positioning block 202 is set in the middle position of the bottom surface of the bottom draw plate 2. In the normal collection state, the bottom draw plate 2 is locked in the frame of the main body 1 of the cultural relics cabinet, and the cultural relics are protected all around. Only after pressing the corresponding unlocking button on the button panel 7, the electromagnet 6 loses power, and the bottom draw plate 2 can be pulled outward along the linear guide 4. By setting the wire length of the wire brush to be slightly larger than the spacing, it can be ensured that when the electromagnet 6 sucks the wire brush tightly, the wire of the bottom draw plate 2 moves slightly forward and backward, and only bends and deforms, and does not separate from the electromagnet 6, which can buffer the transverse wave vibration along the linear guide 4 in the event of an earthquake. By setting the outer limit assembly on the front and rear sides of the base 3, the bottom draw plate 2 can be limited to avoid overshoot and inertial collision; the wire brush is blocked by the inward bevel of the inclined block 801, and the contact process is flexible, and the wire brush is bent and deformed to buffer the inertial impact force of the outward movement, avoiding the impact and collision of the cultural relics. At the same time, the squeezed and deformed wire brush can also lock the position of the bottom draw plate 2 to prevent the bottom draw plate 2 from turning back after the inertia is blocked. The inclined block 801 is installed on the upward piston rod end of the first acting cylinder 8, so that the inclined block 801 can be hidden when not in use to prevent the inclined block 801 from being stepped on. By adding a cover plate 9 and a second acting cylinder 10, the second positioning hole 305 can be electrically closed to prevent debris from falling into the hole. The setting of the covering guide frame 901 ensures that the covering plate 9 has sufficient support strength.
