Description

Technical Field

[0001] The utility model relates to the technical field of study table manufacturing, in particular to a study table with an adjustable tabletop angle. Background Art

[0002] In order to facilitate users to maintain a comfortable reading and writing posture for a long time when sitting upright, the desktop angle adjustable study table came into being. In actual application, users can adjust the tilt angle of the desktop according to different learning states.

[0003] As far as the current situation is concerned, many manufacturers have developed a wide variety of desktop angle adjustable study tables. The more common type is the upper-type desktop angle adjustable study table, such as Figure 1 As shown in , when the movable table top is adjusted to a tilted position, a gap is formed between the movable table top and the fixed table top, and the gap value gradually increases from the front to the back. The tilt angle of the movable table top is maintained by means of a gas spring and a folding frame with a damping function. Both the gas spring and the folding frame with a damping function are directly installed on the movable table top. However, the movable table top is made of wood or engineering plastic, and its structural strength is relatively weak, resulting in extremely limited stability in the connection between the gas spring and the folding frame and the movable table top. In addition, the locking retention force that the gas spring and the folding frame can provide for the movable table top is relatively limited. In actual use, the movable table top is very likely to accidentally flip over and reset due to excessive pressure, which in turn causes the user's fingers to be easily crushed if they are not careful and place them in the gap. Therefore, technical personnel are urgently needed to solve the above problems. Utility Model Content

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience by technicians engaged in this industry, which ultimately led to the emergence of the study table with adjustable desktop angle.

[0005] In order to solve the above-mentioned technical problems, the utility model relates to a study table with adjustable desktop angle, comprising a support assembly, a top support assembly and a desktop panel assembly. The top support assembly is used to carry the desktop panel assembly, and is supported by the support assembly. The desktop panel assembly is composed of a rear flat panel and a front tilting panel that are independent of each other. The top support assembly includes a rear top support frame, a front top support frame and a telescopic hovering mechanism. The rear top support frame and the front top support frame serve as the installation base for the rear flat panel and the front tilting panel, respectively. The rear top support frame is assembled into one with the support assembly, and is assembled with the front top support frame in a hinged connection. The telescopic hovering mechanism simultaneously connects the rear top support frame and the front top support frame. Under the action of the telescopic hovering mechanism, the front top support frame can perform a tilting motion relative to the rear top support frame, and can hover at any angle. The telescopic hovering mechanism includes a rear hinge, a front hinge, a rear pin, a center pin, a front pin, an optional air spring, a U-shaped connecting transition piece, and a hovering control handpiece. The rear hinge uses the bottom wall of the rear top support frame as its mounting base. The front hinge uses the bottom wall of the front top support frame as its mounting base and maintains alignment with the rear hinge. The U-shaped connecting transition piece is fitted onto the piston rod of the optional air spring and is locked with the aid of a double nut. The cylinder of the optional air spring and the rear hinge are articulated by means of the rear pin. The U-shaped connecting transition piece and the front hinge are articulated by means of the front pin. The hovering control handpiece and the U-shaped connecting transition piece are articulated by means of the center pin, and are aligned with the starting rod of the optional air spring.

[0006] As a further improvement to the technical solution disclosed in this utility model, the hover control handpiece is preferably a one-piece bent sheet metal component, sequentially connected by a push-up section, a hinge section, and a gripping section. The hinge section is formed with a mounting hole for inserting a center pin. As the hover control handpiece rotates circumferentially, the push-up section transmits a pushing force to the actuating lever of the optional gas spring.

[0007] As a further improvement to the technical solution disclosed in this utility model, the telescopic hovering mechanism also includes a self-lubricating plastic plate. This plate is in contact with the top section and is removably fixed to form a single unit. During the circumferential rotation of the hovering control handpiece, the actuating rod of the optional gas spring constantly elastically presses against the self-lubricating plastic plate and slides along its sidewalls.

[0008] As a further improvement of the technical solution disclosed in the present invention, after the hover control handpiece is assembled relative to the U-shaped connection transition piece, the left and right free ends of the center pin shaft do not extend beyond the U-shaped connection transition piece to avoid the front hinge seat.

[0009] As a further improvement to the disclosed technical solution of the present utility model, the rear support top frame is in the shape of a cuboid and is assembled and welded by multiple sections of square tube profiles. The front support top frame is in a "U" shape and is also assembled and welded by multiple sections of square tube profiles.

[0010] As a further improvement to the disclosed technical solution of the present utility model, the number of telescopic hovering mechanisms is 2, and they are evenly distributed along the width direction of the support top assembly.

[0011] As a further improvement to the disclosed technical solution of the present utility model, the support assembly includes a left anti-tipping leg, a right anti-tipping leg, a left support leg assembly, a right support leg assembly, and a connecting beam. The left support leg assembly and the right support leg assembly cooperate to bear the rear support top frame, and the connecting beam is detachably connected between the two. The horizontally arranged left anti-tipping leg and the left support leg assembly are assembled into one body in a detachable manner and are perpendicular to each other. The horizontally arranged right anti-tipping leg and the right support leg assembly are assembled into one body in a detachable manner and are perpendicular to each other.

[0012] As a further improvement to the disclosed technical solution of the present utility model, the support assembly further includes a left rubber buffer and a right rubber buffer. The left rubber buffer is detachably fixed to the bottom wall of the left anti-tipping leg. The number of the left rubber buffers is set to be multiple and they are evenly distributed along the length direction of the left anti-tipping leg. The right rubber buffer is detachably fixed to the bottom wall of the right anti-tipping leg. The number of the right rubber buffers is set to be multiple and they are evenly distributed along the length direction of the right anti-tipping leg.

[0013] In practical applications, the desktop angle-adjustable study table disclosed by the present utility model can at least achieve the following beneficial technical effects: specifically,

[0014] 1) Under the action of the telescopic hovering mechanism, the front tilting panel used for desk study can perform tilting movement relative to the rear flat panel and can hover at any angle. Thus, the levelness of the front tilting panel can be freely adjusted according to the psychological expectations of the user, which is beneficial for the user to maintain a comfortable reading and writing posture in a natural sitting upright state for a long time;

[0015] 2) After the levelness of the front tilting panel is adjusted, the tilting movement of the front tilting panel caused by the accidental unlocking of the telescopic hovering mechanism is unidirectional. And even if the starting rod of the gas spring is accidentally touched and the posture locking function of the telescopic hovering mechanism fails, the front tilting panel can only perform tilting movement in the clockwise direction, effectively preventing the occurrence of the phenomenon that the user's fingers are accidentally injured;

[0016] 3) When the horizontality of the front tilt panel needs to be adjusted, the user only needs to turn the hover control handpiece counterclockwise, and the starting rod of the optional air spring will retract due to the pushing force, and the optional air spring will use the external force to offset the pressure difference to shorten its own length. At the same time, the horizontality of the front tilt panel will adapt until it meets the user's psychological expectations. Then, the user completely releases the hover control handpiece, and the starting rod of the optional air spring will be extended and reset. When the front tilt panel needs to be reset, the user needs to turn the hover control handpiece counterclockwise again, and the starting rod of the optional air spring will retract again due to the pushing force. The optional air spring will use the pressure difference on both sides of the piston to extend its own length, and the front tilt panel will tilt in the opposite direction until it meets the user's psychological expectations. As can be seen from the above description, the entire operation process of adjusting the horizontality of the front tilt panel is convenient and quick, and during the adjustment process, the user only needs to apply a very small force to the front tilt panel for assistance.

[0017] 4) When the starting rod of the optional air stop spring is not pressed and remains in the initial position, the length of the optional air stop spring remains at a constant value even if it is subjected to axial force, which means that the horizontality of the front tilting panel remains unchanged for a long time when it is subjected to pressure.

DETAILED DESCRIPTION

[0034] In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0035] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 2 、 Figure 3 The three-dimensional schematic diagrams of the desktop angle adjustable study table disclosed by the present invention are respectively shown in two different states. It can be seen that it is mainly composed of several parts such as a support component 1, a top support component 2, a desktop panel component 3 and a baffle component 4. Among them, the support component 1 is directly placed on the floor of the room. The top support component 2 is used to support the desktop panel component 3, and it is supported by the support component 1. The desktop panel component 3 is composed of a rear flat panel 31 and a front tilting panel 32 that are independent of each other. Figure 6 、 7 As shown in the figure, the roof supporting assembly 2 is mainly composed of several parts such as a rear roof supporting frame 21, a front roof supporting frame 22 and a telescopic hovering mechanism 23. The rear roof supporting frame 21 and the front roof supporting frame 22 serve as the installation base for the rear flat panel 31 and the front tilting panel 32 respectively. The rear roof supporting frame 21 is assembled into one with the support assembly 1, and it is assembled with the front roof supporting frame 22 in a hinged connection manner. The telescopic hovering mechanism 23 connects the rear roof supporting frame 21 and the front roof supporting frame 22 at the same time. The number of telescopic hovering mechanisms is 2, and they are evenly distributed along the width direction of the roof supporting assembly 2. Under the action of the telescopic hovering mechanism 23, the front roof supporting frame 22 can perform tilting movement relative to the rear roof supporting frame 21, and can hover at any angle. In actual applications, with the help of the telescopic hovering mechanism 23, the front tilting panel 32 used for desk learning can perform tilting movement relative to the rear flat panel 31, and can hover at any angle. In this way, the horizontality of the front tilting panel can be freely adjusted according to the user's psychological expectations, which is beneficial for the user to maintain a comfortable reading and writing posture for a long time in a natural sitting upright state, making it consistent with the ergonomic design concept.

[0036] like Figure 8-13As shown in the figure, taking the telescopic hovering mechanism 23 on one side as an example, it is mainly composed of several parts such as the rear hinge 231, the front hinge 232, the rear pin 233, the middle pin 234, the front pin 235, the optional air spring 236, the U-shaped connecting transition piece 237 and the hovering control handpiece 238. Among them, the rear hinge 231 uses the bottom wall of the rear support frame 21 as the installation base. The front hinge 232 uses the bottom wall of the front support frame 22 as the installation base and maintains alignment with the rear hinge 231. The U-shaped connecting transition piece 237 is mounted on the piston rod of the optional air spring 236 and is locked with the help of a double nut. The cylinder body of the optional air spring 236 and the rear hinge 231 are assembled in an articulated connection with the help of the rear pin 233. The U-shaped transition piece 237 and the front hinge 232 are articulated together using a front pin 235. The hover control handpiece 238 is articulated together with the U-shaped transition piece 237 using a center pin 234, which is aligned with the actuating lever of the optional air spring 236. It is particularly important to note that when the hover control handpiece 238 is assembled with the U-shaped transition piece 237, the left and right free ends of the center pin 234 do not extend beyond the U-shaped transition piece 237, avoiding the front hinge 232.

[0037] In practice, when the horizontality of the front tilt panel 32 needs to be adjusted, the user can simultaneously move the two hover control handpieces 238 with both hands to freely switch the front tilt panel 32 between the horizontal, tilted, and drooped positions. Under the action of the rotational torque, the hover control handpiece 238 performs a circumferential yaw motion about the central axis of the center pin 234. The actuating rod of the optional air spring 236, acting under the pressure of the hover control handpiece 238, performs a telescoping motion, thereby switching the operating mode of the optional air spring 236 and enabling the front tilt panel 32 to hover at any angle. Specifically, when it is necessary to adjust the horizontality of the front tilt panel 32, the user only needs to pull the hover control handpiece 238 counterclockwise, and the starting rod of the optional air stop spring 236 will retract due to the pushing force, and the optional air stop spring 236 can use the external force to offset the pressure difference to shorten its own length. At the same time, the horizontality of the front tilt panel 32 will adapt to the change until it meets the user's psychological expectations. Then, the user completely releases the hover control handpiece 238, and the starting rod of the optional air stop spring 236 can be extended and reset; and when it is necessary to reset the front tilt panel 32, the user needs to pull the hover control handpiece 238 counterclockwise again, and the starting rod of the optional air stop spring 236 will retract again due to the pushing force, and the optional air stop spring 236 can extend its own length with the help of the pressure difference on both sides of the piston, and the front tilt panel 32 can tilt in the opposite direction until it meets the user's psychological expectations. As can be seen from the above description, the entire operation process of adjusting the horizontality of the front tilting panel 32 is convenient and quick, and during the adjustment process, the user only needs to apply a very small force to the front tilting panel 32 for assistance.

[0038] In actual use, once the level of the front tilt panel 32 has been adjusted, the tilting movement of the front tilt panel 32 caused by accidental unlocking of the telescopic hovering mechanism 23 is unidirectional. Even if the activation lever of the random stop gas spring 236 is accidentally activated, rendering the telescopic hovering mechanism 23's posture locking function ineffective, the front tilt panel 32 can only tilt in a clockwise direction. Furthermore, under normal use, to adjust the level of the front tilt panel 32, the user must simultaneously actuate the two hovering control handpieces 238 with their left and right hands, respectively. These two factors effectively prevent the user's fingers from being accidentally crushed.

[0039] Furthermore, it should be noted that when the starting rod of the optional air stop spring 236 is not pressed and remains in the initial position, the length of the optional air stop spring 236 remains at a constant value even if it is subjected to axial force, which means that when the front tilting panel 32 is subjected to the pressing force, its horizontality remains unchanged for a long time.

[0040] like Figure 14 As shown in Figure 14 , the hovering control handle 238 is an integrally formed sheet metal bending part, which is sequentially connected by a pushing section 2381, a hinged section 2382, and a hand-holding section 2383. An installation hole 23821 for inserting the middle pin 234 is formed on the hinged section 2382.

shown in the figure, the support assembly 1 is mainly composed of the left anti-tilt leg 11, the right anti-tilt leg 12, the left support leg assembly 13, the right support leg assembly 14 and the connecting beam 15. The left support leg assembly 13 and the right support leg assembly 14 cooperate to support the rear roof support frame 21, and the connecting beam 15 is detachably connected between the two. The left anti-tilt leg 11 and the left support leg assembly 13, which are arranged horizontally, are detachably assembled into one body, and the two are perpendicular to each other. The right anti-tilt leg 12 and the right support leg assembly 14, which are arranged horizontally, are detachably assembled into one body, and the two are perpendicular to each other. In this way, on the one hand, it ensures that the desktop angle adjustable study table has good center of gravity stability, effectively avoiding the occurrence of the desktop panel assembly 3 tipping over due to excessive pressure; on the other hand, after the assembly is completed, the support assembly 1 has good structural strength and posture stability, which is conducive to effectively improving the service life of the desktop angle adjustable study table; on the other hand, the support assembly 1 has a very simple design structure, and the assembly method is extremely simple, which is conducive to users to perform assembly operations by themselves.

[0044] Depend on Figure 5 It can also be clearly seen from the figure that the support assembly 1 is further provided with a left-mounted rubber buffer 16 and a right-mounted rubber buffer 17. The left-mounted rubber buffer 16 is fixed to the bottom wall of the left anti-tilt leg 11 in a detachable manner, and the number of the left-mounted rubber buffer 16 is set to multiple and evenly distributed along the length direction of the left anti-tilt leg 11. The right-mounted rubber buffer 17 is fixed to the bottom wall of the right anti-tilt leg 12 in a detachable manner, and the number of the right-mounted rubber buffer 17 is set to multiple and evenly distributed along the length direction of the right anti-tilt leg 12. In this way, on the one hand, in actual application, the left-mounted rubber buffer 16 and the right-mounted rubber buffer 17 both have the characteristics of adaptive elastic deformation due to pressure, which is conducive to the smooth implementation of the leveling operation of the desktop angle adjustable study table; on the other hand, it prevents the left anti-tilt leg 11 and the right anti-tilt leg 12 from being worn due to direct contact with the ground.
