Description

Technical Field

[0001] This invention relates to a darkroom desk, specifically a darkroom structure and a desk. Background Technology

[0002] A hidden or enclosed storage space is typically used to store items without them being easily noticed. In office desks, a hidden storage space can refer to a design that includes concealed storage areas or drawers, designed to maximize space utilization and keep the desktop tidy.

[0003] Chinese patent publication number CN211599187U discloses "a desktop connection structure and an office desk", which includes multiple support beams, connecting blocks and rotating parts. The above-mentioned device connects the support beams into a whole through the connecting parts. The rotating parts are set on the support beams. The connection between the rotating parts and the desktop does not require screws to pass through the crossbeams, so the connection is more convenient. Moreover, the support blocks on the rotating parts increase the contact area between the rotating parts and the desktop, thereby increasing the stability between the rotating parts and the desktop. The connecting blocks are set on the support beams, so that the support beams are connected into a whole. The connecting blocks are also connected to the table legs, making the support beams and table legs a whole structure, and the overall office desk is more aesthetically pleasing.

[0004] In the aforementioned patent, the connection between the rotating component and the desktop does not require screws to pass through the crossbeam, making the connection more convenient. Furthermore, the support block on the rotating component increases the contact area between the rotating component and the desktop, thereby increasing the stability between the rotating component and the desktop. The supporting crossbeam is equipped with a connecting block, making the supporting crossbeam a whole. Moreover, the connecting block is also connected to the table legs, making the supporting beam and table legs a single structure, resulting in a more aesthetically pleasing overall desk. However, when pulling out and closing the drawers inside the desk, incompletely closing the drawers can affect the normal work of office workers and pose a potential hazard. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a darkroom structure and an office desk, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides a dark box structure, including support legs, a fixed horizontal plate fixedly installed between the support legs, a table fixedly installed on the top of the support legs, a circular hole on the surface of the table, a spiral groove inside the circular hole, a coil slidably installed on the inner wall of the spiral groove, a display screen on the top of the table, a chassis at the bottom of the table, the display screen being electrically connected to the chassis, and a fixing screw rotatably installed between the support legs and the fixed horizontal plate, the fixing screw rotating through the inner and outer walls of the support legs.

[0007] The present invention also provides an office desk, including a storage table, a storage box on the top of the storage table, a desk lamp on the top of the storage table, a cabinet door rotatably installed on the surface of the storage table, and a storage device, a buffer device, and a protective device inside the storage table.

[0008] The storage device includes a storage slot, a concealed drawer, a handle, a baffle, a spring, a lead screw, an unlocking block, a fixing component, a rotating plate, a square block, a limiting block, a hollow box, an inclined block, and a locking tongue. The storage slot is located inside the storage table. The concealed drawer slides along the inner wall of the storage slot. The handle is fixed to the outer surface of the concealed drawer. The baffle is fixed to the inner wall of the storage slot. The spring is fixed to the inner wall of the storage slot. The lead screw rotates through the inner and outer walls of the baffle. The end of the lead screw near the spring is rotatably mounted on the inner wall surface of the storage slot. The unlocking block is fixed to the circumference of the lead screw. The fixing component is fixed to the bottom of the inner wall of the storage slot. The lead screw is rotatably mounted on the inner wall of the fixing component's circumference. The rotating plate is fixed to the end of the lead screw near the spring. The square block is fixedly installed on the bottom of the inner wall of the storage slot. The limiting block is fixedly installed on the side of the square block near the dark drawer. The hollow box is fixedly installed on the side of the dark drawer near the storage spring. The inclined block is slidably installed on the inner wall of the hollow box. The locking tongue is fixedly installed on the side of the inclined block near the square block. When the dark drawer moves, it will cause the hollow box to move towards the storage spring. When the hollow box moves, it will cause the inclined block to move towards the storage spring. After the inclined block moves, it no longer contacts the limiting block. After the inclined block no longer contacts the limiting block, it will move towards the bottom through the reset of the first spring. After the inclined block moves towards the bottom, it will be blocked by the limiting block, so that the inclined block cannot move outward. After the inclined block cannot move, the dark drawer cannot move. The limiting block limits the inclined block.

[0009] Furthermore, a first spring is provided between the hollow box and the inclined block, and the rotating plate contacts the locking tongue, so that the inclined block is reset by the first spring.

[0010] Furthermore, the limiting block contacts the inclined block, and a torsion spring is provided between the lead screw and the baffle, which drives the lead screw to reset.

[0011] Furthermore, the buffer device includes a spring, a transmission plate, a telescopic rod, an L-shaped plate, and a friction plate. The spring is fixedly installed on the side of the drawer near the square block, the transmission plate is fixedly installed on the side of the drawer near the square block, the telescopic rod is fixedly installed on the side of the baffle near the storage spring, the L-shaped plate is fixedly installed on the free end surface of the telescopic rod, and the friction plate is slidably installed on the inner wall of the storage slot. After the spring contacts the friction plate, the spring deforms itself, increasing the contact area between the spring and the friction plate. The increased contact area between the spring and the friction plate increases the resistance when the spring moves, which in turn reduces the speed of the drawer moving away from the storage spring.

[0012] Furthermore, a second spring is provided between the friction plate and the storage groove. The friction plate contacts the L-shaped plate. A return spring is provided inside the telescopic rod. The return spring drives the telescopic rod to return to its original position, and the second spring drives the friction plate to return to its original position.

[0013] Furthermore, the buffer device also includes a rotating rod, a reset plate, a first rotating plate, a second rotating plate, and a blocking rod. The rotating rod is rotatably mounted on the top of the inner wall of the storage slot. The reset plate is fixedly mounted on the circumferential surface of the rotating rod. The first rotating plate is fixedly mounted on the side of the dark drawer near the square block. The second rotating plate is rotatably mounted on the surface of the first rotating plate. The blocking rod is fixedly mounted on the side of the dark drawer near the square block. The rotation of the reset plate will push the friction plate to move towards the spring. After the friction plate moves, it will no longer block the L-shaped plate. After the friction plate no longer blocks the L-shaped plate, the reset spring will reset and drive the free end of the telescopic rod to move towards the friction plate. The reset and the movement of the free end of the telescopic rod will drive the L-shaped plate to move. The movement of the L-shaped plate will limit the friction plate again.

[0014] Furthermore, a second torsion spring is provided between the rotating rod and the storage slot, and the second rotating plate contacts the reset plate, thereby driving the rotating rod to reset through the second torsion spring.

[0015] Furthermore, the protective device includes a sliding rod, a limiting slot, a hollow block, a sliding plate, a U-shaped rod, a locking block, a No. 3 spring, an arc-shaped rod, and a locking groove. The sliding rod is fixedly installed on the bottom of the inner wall of the storage slot. The limiting slot is formed on the surface of the sliding rod. The hollow block is fixedly installed on the side of the drawer near the sliding rod. The sliding plate is slidably installed on the inner wall of the hollow block. The U-shaped rod is fixedly installed on the bottom of the sliding plate. The locking block is fixedly installed on the end of the U-shaped rod away from the sliding plate. The arc-shaped rod rotates through the hollow block. The inner and outer walls of the block have the locking groove on the surface of the drawer near the sliding rod. When the sliding plate moves, it will cause the U-shaped rod to move away from the storage spring. The movement of the U-shaped rod will cause the locking block to move at the top of the sliding rod. When the locking block moves to the limiting groove, the sliding plate will move to the bottom through the reset of the No. 3 spring. The movement of the sliding plate will cause the U-shaped rod to move to the bottom. The movement of the U-shaped rod to the bottom will cause the locking block to move to the bottom. The movement of the locking block to the bottom will lock into the limiting groove. After the locking block is locked into the limiting groove, the locking block can no longer move.

[0016] Furthermore, a No. 3 spring is provided between the sliding plate and the hollow block, and the locking block contacts the limiting slot, so that the sliding plate is reset by the No. 3 spring.

[0017] This invention provides a dark box structure and an office desk, which have the following beneficial effects:

[0018] Firstly, in this invention, the inclined block is blocked by the limiting block after moving to the bottom, preventing the inclined block from moving outward. The inability of the inclined block to move prevents the dark drawer from moving. By limiting the inclined block, the dark drawer can be automatically limited when it is closed, eliminating the need for manual locking, making it convenient to use and improving the comfort of using the device. By rotating the unlocking block, the limitation on the dark drawer can be quickly released and the dark drawer can be popped out without manually pulling it open, preventing the dark drawer from being too difficult to open by hand due to too many items inside, further improving the comfort of using the device.

[0019] Secondly, in this invention, after the inclined block moves to the bottom, it is blocked by the limiting block, preventing the inclined block from moving outward. After the spring plate deforms, it increases the contact area between the spring plate and the friction plate. The increased contact area between the spring plate and the friction plate increases the resistance when the spring plate moves. The increased resistance reduces the speed of the drawer away from the storage spring, preventing the drawer from popping out too quickly after the storage spring releases its stored force, which could cause the drawer to hit the user's hand and cause injury. This improves the device's protection for personnel. Since the friction plate no longer contacts the spring plate, the drawer is no longer affected by resistance, so there is no deceleration effect when the drawer is pushed inward. This prevents excessive resistance from preventing the user from closing the drawer, improving the device's practicality. The movement of the L-shaped plate will re-limit the friction plate, so that the buffer device will return to its initial state when the drawer is closed, without hindering the buffering work again, further improving the device's practicality.

[0020] Thirdly, in this invention, the inclined block is blocked by the limiting block after moving to the bottom, preventing the inclined block from moving outward. After the locking block is engaged in the limiting slot, the locking block cannot move further, preventing the dark drawer from moving further. This prevents the dark drawer from popping outward when it reaches the outermost position, thus preventing the dark drawer from being ejected from the storage slot when the stored spring releases its stored force, causing the dark drawer to separate from the storage table and rendering the device unusable. This improves the stability of the device during use. After the arc rod is engaged in the locking slot, the contact between the locking block and the limiting slot makes the connection between the dark drawer and the storage slot more stable, preventing the dark drawer from tipping over due to inertia after it pops out, and further improving the stability and practicality of the device.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 - Figure 10This invention provides a dark box structure and an office desk, including support legs 1, a fixed horizontal plate 2 fixedly installed between the support legs 1, a tabletop 3 fixedly installed on the top of the support legs 1, a circular hole on the surface of the tabletop 3, a spiral groove inside the circular hole, a coil 4 slidably installed on the inner wall of the spiral groove, a display screen 5 on the top of the tabletop 3, a housing 6 on the bottom of the tabletop 3, the display screen 5 and the housing 6 being electrically connected, and a fixing screw 7 rotatably installed between the support legs 1 and the fixed horizontal plate 2, the fixing screw 7 rotating through the inner and outer walls of the support legs 1.

[0034] The storage table 8 includes a storage box 9 on its top and a table lamp 10 on its top. A cabinet door 11 is rotatably mounted on the surface of the storage table 8. The interior of the storage table 8 contains a storage device, including a storage slot 1201, a hidden drawer 1202, a handle 1203, a baffle 1204, a spring 1205, a lead screw 1206, an unlocking block 1207, a fixing piece 1208, a rotating plate 1209, a square block 1210, a limiting block 1211, a hollow box 1212, a beveled block 1213, and a locking tongue 1. 214. A storage slot 1201 is located inside the storage table 8. A hidden drawer 1202 is slidably mounted on the inner wall of the storage slot 1201. A handle 1203 is fixedly mounted on the outer wall of the hidden drawer 1202. A baffle 1204 is fixedly mounted on the inner wall of the storage slot 1201. A storage spring 1205 is fixedly mounted on the inner wall of the storage slot 1201. A lead screw 1206 rotates through the inner and outer walls of the baffle 1204. The end of the lead screw 1206 near the storage spring 1205 is rotatably mounted on the inner wall of the storage slot 1201. An unlocking block 120... 7. Fixedly installed on the circumferential surface of the lead screw 1206; fixedly installed on the bottom inner wall of the storage slot 1201; the lead screw 1206 is rotatably installed on the inner wall of the circumferential surface of the fixedly installed 1208; the rotating plate 1209 is fixedly installed on the circumferential surface of the lead screw 1206 near the end of the storage spring 1205; the square block 1210 is fixedly installed on the bottom inner wall of the storage slot 1201; the limiting block 1211 is fixedly installed on the side of the square block 1210 near the hidden drawer 1202; the hollow box 1212 is fixedly installed on the side of the hidden drawer 1202 near the storage spring 1205. One side of the force spring 1205 and the inclined block 1213 are slidably installed on the inner wall of the hollow box 1212. When the hidden drawer 1202 is closed, it automatically limits the drawer's movement, eliminating the need for manual locking and improving ease of use. The locking tongue 1214 is fixedly installed on the side of the inclined block 1213 near the square block 1210, preventing the hidden drawer 1202 from being manually pulled open and avoiding excessive effort when opening it due to too many items inside, further enhancing the comfort of use.

[0035] A first spring 1215 is provided between the hollow box 1212 and the inclined block 1213. The rotating plate 1209 contacts the locking tongue 1214, and the first spring 1215 drives the inclined block 1213 to reset.

[0036] The limiting block 1211 contacts the inclined block 1213, and a torsion spring is provided between the lead screw 1206 and the baffle 1204. The lead screw 1206 is reset by the torsion spring.

[0037] In this embodiment, during operation: Manually pushing the handle 1203 moves the hidden drawer 1202, which in turn moves the hollow box 1212 towards the storage spring 1205. The hollow box 1212 then moves the inclined block 1213 towards the storage spring 1205. The inclined block 1213 then contacts the limiting block 1211, which blocks its movement. After being blocked by the limiting block 1211, the inclined block 1213 moves upwards. This upward movement of the inclined block 1213 then affects the first spring 12... 15. As the hidden drawer 1202 continues to move, it causes the hollow box 1212 to move towards the storage spring 1205. The hollow box 1212 then moves the inclined block 1213 towards the storage spring 1205. After moving, the inclined block 1213 no longer contacts the limiting block 1211. Once no longer in contact with the limiting block 1211, the inclined block 1213 is reset by the first spring 1215, causing it to move towards the bottom. After moving towards the bottom, the inclined block 1213 is blocked by the limiting block 1211, preventing it from moving outwards. After block 213 becomes immobile, drawer 1202 cannot move. Limiting block 1211 restricts the inclined block 1213, automatically locking drawer 1202 when it is closed, eliminating the need for manual locking and improving ease of use. Manually rotating unlocking block 1207 rotates screw 1206, which in turn rotates rotating plate 1209. Rotating plate 1209 contacts latch 1214, causing latch 1214 to move upwards. Moving the device upwards will cause the inclined block 1213 to move upwards as well. After the inclined block 1213 moves upwards, it will no longer be in contact with the limiting block 1211. Once the inclined block 1213 is no longer in contact with the limiting block 1211, it will reset through the storage spring 1205, causing the dark drawer 1202 to move away from the square block 1210. By rotating the unlocking block 1207, the limiting of the dark drawer 1202 can be quickly released and the dark drawer 1202 can be popped out. There is no need to manually pull open the dark drawer 1202, which prevents the dark drawer 1202 from being too difficult to open by hand due to too many items inside, and further improves the comfort of using the device.

[0038] Please see Figure 1 - Figure 10The storage table 8 is equipped with a buffer device and a protective device inside. The buffer device includes a spring 1301, a transmission plate 1302, a telescopic rod 1303, an L-shaped plate 1304, and a friction plate 1305. The spring 1301 is fixedly installed on the side of the hidden drawer 1202 near the square block 1210. The transmission plate 1302 is fixedly installed on the side of the hidden drawer 1202 near the square block 1210. The telescopic rod 1303 is fixedly installed on the side of the baffle 1204 near the storage spring 1205. The L-shaped plate 1304 is fixedly installed on the free end surface of the telescopic rod 1303. The friction plate 1305 is slidably installed on the inner wall of the storage slot 1201 to prevent the hidden drawer 1202 from popping out too quickly after the storage spring 1205 releases its stored force, which could cause the hidden drawer 1202 to hit the user's hand and cause injury. This improves the protection of personnel by the device.

[0039] A second spring 1306 is provided between the friction plate 1305 and the storage groove 1201. The friction plate 1305 is in contact with the L-shaped plate 1304. A return spring is provided inside the telescopic rod 1303. The telescopic rod 1303 is reset by the return spring, and the friction plate 1305 is reset by the second spring 1306.

[0040] The buffer device also includes a rotating rod 1307, a reset plate 1308, a first rotating plate 1309, a second rotating plate 1310, and a blocking rod 1311. The rotating rod 1307 is rotatably mounted on the top of the inner wall of the storage slot 1201. The reset plate 1308 is fixedly mounted on the circumferential surface of the rotating rod 1307. The first rotating plate 1309 is fixedly mounted on the side of the dark drawer 1202 near the square block 1210. The second rotating plate 1310 is rotatably mounted on the surface of the first rotating plate 1309. The blocking rod 1311 is fixedly mounted on the side of the dark drawer 1202 near the square block 1210, so that when the dark drawer 1202 is closed, the buffer device will return to its initial state, without hindering the buffering operation again, thus improving the practicality of the device.

[0041] A second torsion spring is provided between the rotating rod 1307 and the storage slot 1201. The second rotating plate 1310 contacts the reset plate 1308, and the rotating rod 1307 is reset through the second torsion spring.

[0042] The protective device includes a sliding rod 1401, a limiting slot 1402, a hollow block 1403, a sliding plate 1404, a U-shaped rod 1405, a locking block 1406, a No. 3 spring 1407, an arc-shaped rod 1408, and a locking groove 1409. The sliding rod 1401 is fixedly installed on the bottom of the inner wall of the storage slot 1201. The limiting slot 1402 is formed on the surface of the sliding rod 1401. The hollow block 1403 is fixedly installed on the side of the drawer 1202 near the sliding rod 1401. The sliding plate 1404 is slidably installed on the inner wall of the hollow block 1403. The U-shaped rod 1405 is fixedly installed on the bottom of the sliding plate 1404. The locking block 1406 is fixedly installed on the U-shaped rod 1407. The end of 405 away from the sliding plate 1404 prevents the storage drawer 1202 from being ejected from the storage slot 1201 when the storage spring 1205 releases its stored force, which would cause the storage drawer 1202 to separate from the storage table 8 and render the device unusable. This improves the stability of the device during use. The arc rod 1408 rotates through the inner and outer walls of the hollow block 1403. The locking groove 1409 is opened on the surface of the storage drawer 1202 near the sliding rod 1401 to prevent the items inside the storage drawer 1202 from piling up to the outside due to inertia after the storage drawer 1202 is ejected, thus preventing the storage drawer 1202 from tipping over. This further improves the stability and practicality of the device.

[0043] A third spring 1407 is provided between the sliding plate 1404 and the hollow block 1403. The locking block 1406 contacts the limiting slot 1402, and the sliding plate 1404 is reset by the third spring 1407.

[0044] In this embodiment, when the drawer 1202 moves away from the spring 1205, the movement of the drawer 1202 will cause the spring 1301 to move away from the spring 1205. The spring 1301 will then contact the friction plate 1305, causing it to deform. This deformation increases the contact area between the spring 1301 and the friction plate 1305. This increased contact area increases the resistance to the movement of the spring 1301, thus reducing the speed of the drawer 1202 as it moves away from the spring 1205, preventing the spring 1205 from releasing its stored energy. After the force is applied, the drawer 1202 pops out too quickly, which may cause it to hit the user's hand, resulting in hand injury. This improves the device's protection for personnel. The drawer 1202 moving away from the storage spring 1205 will cause the transmission plate 1302 to move away from the storage spring 1205. The transmission plate 1302, moving away from the storage spring 1205, will contact the L-shaped plate 1304. The movement of the transmission plate 1302 will then cause the L-shaped plate 1304 to move towards the baffle 1204. After moving, the L-shaped plate 1304 will no longer contact the friction plate 1305. Once the L-shaped plate 1304 is no longer in contact with the friction plate 1305, it no longer limits the movement of the friction plate 1305. After the friction plate 1305 loses its limit position, it is reset by the second spring 1306, causing the friction plate 1305 to move away from the spring piece 1301. After the friction plate 1305 moves, it no longer contacts the spring piece 1301. Since the friction plate 1305 no longer contacts the spring piece 1301, the drawer 1202 is no longer affected by resistance. This prevents the drawer 1202 from being slowed down when pushed inward, thus preventing excessive resistance from preventing the user from closing the drawer 1202 and improving the practicality of the device. When the drawer 1202 moves towards the storage spring 1205, the movement of the drawer 1202 will cause the rotating plate 1309 to move towards the storage spring 1205. The movement of the rotating plate 1309 will then cause the rotating plate 1202 to move towards the storage spring 1205. 310 moves towards the storage spring 1205. The second rotating plate 1310, upon contact with the reset plate 1308, is blocked by the blocking rod 1311, preventing it from rotating towards the blocking rod 1311. After rotating, the second rotating plate 1310 pushes the reset plate 1308 to rotate. The reset plate 1308 then contacts the friction plate 1305, which in turn pushes it towards the spring piece 1301. After moving, the friction plate 1305 no longer blocks the L-shaped plate 1304. Once the friction plate 1305 no longer blocks the L-shaped plate 1304, the reset spring resets the free end of the telescopic rod 1303, causing it to move towards the friction plate 1305.The reset mechanism moves the free end of the telescopic rod 1303, which in turn moves the L-shaped plate 1304. The movement of the L-shaped plate 1304 then repositions the friction plate 1305, ensuring that the buffer device returns to its initial state when the drawer 1202 is closed. This prevents the buffer from interfering with subsequent operation and improves the device's practicality.

[0045] When the drawer 1202 moves away from the spring 1205, the movement of the drawer 1202 will cause the hollow block 1403 to move away from the spring 1205. The movement of the hollow block 1403 will cause the sliding plate 1404 to move away from the spring 1205. The movement of the sliding plate 1404 will cause the U-shaped rod 1405 to move away from the spring 1205. The movement of the U-shaped rod 1405 will cause the locking block 1406 to move at the top of the sliding rod 1401. When the device moves to the limiting slot 1402, the third spring 1407 resets, causing the sliding plate 1404 to move to the bottom. The movement of the sliding plate 1404 causes the U-shaped rod 1405 to move to the bottom, which in turn causes the locking block 1406 to move to the bottom. The locking block 1406 then engages with the limiting slot 1402. Once engaged, the locking block 1406 cannot move further, thus preventing the drawer 1202 from moving further and thus preventing the drawer from being accessed. When drawer 1202 reaches its outermost position, it cannot continue to pop outwards. This prevents the storage spring 1205 from releasing its stored force and ejecting the hidden drawer 1202 from the storage slot 1201, causing the hidden drawer 1202 to separate from the storage table 8 and rendering the device unusable. This improves the stability of the device during use. When the sliding plate 1404 moves to the bottom, it will contact the curved rod 1408. The movement of the curved rod 1408 will push it to rotate away from the hollow block 1403. The rotation of the curved rod 1408 will contact the locking slot 1. 409. After the curved rod 1408 contacts the locking groove 1409, it will lock into the locking groove 1409. After the curved rod 1408 is locked into the locking groove 1409, it will make the connection between the hidden drawer 1202 and the storage slot 1201 more stable through the contact of the locking block 1406 and the limiting locking groove 1402. This prevents the hidden drawer 1202 from tipping over due to the inertia of the items inside the hidden drawer 1202 after it pops out, thus further improving the stability and practicality of the device.
