[0033] To make the above objects, features and advantages of the present invention more obvious and understandable, the following specifically describes the embodiments of the present invention in conjunction with the accompanying drawings.

[0034] To solve the problem that a study desk suitable for being installed on an ordinary desk can only adjust the angle of the study desktop and cannot move the position of the study desktop in the front-back direction according to requirements, the present invention provides an adjustment bracket. Refer to Figure 1 、 Figure 2 As shown, the adjustment bracket includes a length adjustment structure 1, an angle adjustment structure 2 and a desktop sliding lock 3. Among them, the length adjustment structure 1 is distributed along the horizontal direction and is used to connect with the desktop of an ordinary desk; the length of the adjustment bracket can be adjusted through the length adjustment structure 1, so that the adjustment bracket can be connected with ordinary desks of various size specifications, expanding the usage range of the adjustment bracket; the angle adjustment structure 2 is used to adjust the tilt angle of the study desktop 4, and the front end of the length adjustment structure 1 is connected with the front end of the angle adjustment structure 2; the front end in this application specifically refers to the end close to the user when the adjustment bracket is installed on an ordinary desk.

[0035] The desktop sliding lock 3 is connected with the study desktop 4. The desktop sliding lock 3 is arranged on the angle adjustment structure 2 and is slidably connected with the angle adjustment structure 2. By sliding the desktop sliding lock 3 on the angle adjustment structure 2, the study desktop 4 is driven to slide along the angle adjustment structure 2, thereby realizing the adjustment of the position of the study desktop 4 in the front-back direction.

[0036] Meanwhile, since the desktop sliding lock 3 is connected to the learning desktop 4 and is arranged on the angle adjustment structure 2, the learning desktop 4 is connected to the angle adjustment structure 2 through the desktop sliding lock 3. Thus, when the angle adjustment structure 2 adjusts the tilt angle, it can drive the tilt angle of the learning desktop 4 to change.

[0037] The desktop sliding lock 3 in this application is equivalent to a desktop sliding structure. By arranging the desktop sliding lock 3 on the angle adjustment structure 2, an integrated design of the desktop sliding structure and the angle adjustment structure 2 is realized. This enables the adjustment bracket to not only adjust the tilt angle of the learning desktop 4 but also adjust the position of the learning desktop 4 in the front-back direction, that is, the distance between the learning desktop 4 and the user.

[0038] During the use of this adjustment bracket, first, according to the size of the desktop of the ordinary desk to be connected, the length of the adjustment bracket is adjusted through the length adjustment structure 1 so that the length of the adjustment bracket matches the size of the desktop of the ordinary desk to be connected. Then, the adjustment bracket is connected to the desktop of the ordinary desk through the length adjustment structure 1. Next, according to the usage requirements, the learning desktop 4 is adjusted to the required angle through the angle adjustment structure 2. Then, the position of the learning desktop 4 in the front-back direction is further adjusted through the desktop sliding lock 3 so that the adjusted learning desktop 4 can meet the usage requirements of the user. Similarly, during the adjustment of the learning desktop 4, the position of the learning desktop 4 in the front-back direction can also be adjusted first through the desktop sliding lock 3, and then the tilt angle of the learning desktop 4 is adjusted through the angle adjustment structure 2, or the two adjustment processes are alternated until the learning desktop 4 is adjusted to a position that meets the usage requirements of the user.

[0039] The adjustment bracket provided by the present invention can not only be applied to ordinary desks with various different size specifications but also adjust the tilt angle of the learning desktop 4 and the position of the learning desktop 4 in the front-back direction. Thus, the adjustment bracket has a wide range of applications. At the same time, through the coordinated action of the angle adjustment structure 2 and the desktop sliding lock 3, the learning desktop 4 can be adjusted to a position that meets the usage requirements of the user, improving the comfort of use.

[0040] In addition, through the integrated design of the desktop sliding structure and the angle adjustment structure 2 in this application, the structure of the adjustment bracket is made more compact. Thus, while increasing the adjustment function of the adjustment bracket, the volume of the adjustment bracket is not increased, which is convenient for use.

[0041] To facilitate the connection of the length adjustment structure 1 to the desktop of the ordinary desk, the length adjustment structure 1 includes a telescopic connector 11, and a first clamping member 12 and a second clamping member 13 respectively connected to both ends of the telescopic connector 11. When connecting to the desktop of the ordinary desk, the first clamping member 12 and the second clamping member 13 are respectively clamped at both ends of the desktop of the ordinary desk.

[0042] It is connected to the desktop of a common desk through the clamping action of the telescopic connecting member 11 and the two clamping members provided at both ends thereof, which can avoid damaging the desktop of the common desk; the length of the telescopic connecting member 11 is adjustable, and by adjusting the length of the telescopic connecting member 11, the distance between the first clamping member 12 and the second clamping member 13 is adjusted, so that the adjustment bracket can be applied to common desks of various different sizes and specifications.

[0043] Specifically, in this application, it is preferred that the telescopic connecting member 11 includes two parallel mother rods 111, two parallel sub-rods 112, a fifth support rod 113 vertically connected to the two sub-rods 112, and two second adjustment locks provided in the mother rod 111. The fifth support rod 113 is connected to the end of the sub-rod 112 far from the mother rod 111; one end of the sub-rod 112 is inserted into the mother rod 111, and the sub-rod 112 can slide in the mother rod 111, and the sub-rod 112 is connected to the second adjustment lock; during the process of adjusting the length, the second adjustment lock is unlocked to make the sub-rod 112 slide in the mother rod 111 to adjust the length of the telescopic connecting member 11; when the length of the telescopic connecting member 11 is adjusted to an appropriate length, the mother rod 111 and the sub-rod 112 are locked by the second adjustment lock so that the relative positions of the sub-rod 112 and the mother rod 111 are fixed and the length of the telescopic connecting member 11 remains unchanged.

[0044] The second adjustment lock can be any structure that can lock and unlock the mother rod 111 and the sub-rod 112, and the specific structure of the second adjustment lock is not limited in this application.

[0045] The structures of the first clamping member 12 and the second clamping member 13 can be the same or different; in this application, it is preferred that the first clamping member 12 is connected to the mother rod 111 and the second clamping member 13 is connected to the sub-rod 112. Both the first clamping member 12 and the second clamping member 13 can be clamping structures suitable for clamping the desktop of a common desk. For the sake of easy understanding, one structural form is briefly described below taking the second clamping member 13 as an example.

[0046] See Figure 3 As shown, for the convenience of connecting the second clamping member 13 to the sub-rod 112, connecting rods adapted to the sub-rod 112 are provided at both ends of the second clamping member 13, and the connecting rods are adapted to be inserted into the sub-rod 112 to make the connecting rods slidably connected to the sub-rod 112; to further increase the connection strength between the second clamping member 13 and the sub-rod 112, the second clamping member 13 is also connected to the fifth support rod 113 through an adjustment bolt 5.

[0047] The present application can further set a sliding link of the second adjustment lock in the fifth support rod 113, and set a second switch button 114 of the second adjustment lock above the second support rod 222, so as to realize the integrated design of the adjustment switch of the second adjustment lock and the second clamping member 13 through the fifth support rod 113.

[0048] Specifically, an adjustment cylinder is provided in the fifth support rod 113, and the adjustment cylinder is fixedly connected to the fifth support rod 113; an internal thread adapted to the adjustment bolt 5 is provided in the adjustment cylinder; a through hole through which the adjustment cylinder is adapted to pass is provided on the sliding link provided in the fifth support rod 113, and the inner diameter of the through hole is larger than the outer diameter of the adjustment cylinder, so as to ensure that the operation of the second adjustment lock and the operation of the second clamping member 13 do not interfere with each other; the adjustment bolt 5 passes through the adjustment cylinder and is fixedly connected to the second clamping member 13, that is, one end of the adjustment bolt 5 adjacent to the second clamping member 13 is fixedly connected to the second clamping member 13, and this fixed connection method can be welding or the like.

[0049] By providing the adjustment bolt 5 and the adjustment cylinder, the distance between the first clamping member 12 and the second clamping member 13 can also be finely adjusted, so that the distance between the first clamping member 12 and the second clamping member 13 is more adapted to the size of the ordinary desk top, thereby further improving the connection stability between the length adjustment bracket and the ordinary desk top.

[0050] The specific fine adjustment process is as follows: First, according to the size of the ordinary desk top to be clamped, the distance between the first clamping member 12 and the second clamping member 13 is initially adjusted through the second adjustment lock, and then by rotating the adjustment bolt 5, the second clamping member 13 is driven to move away from or close to the sub-rod 112, so as to further increase or decrease the distance between the first clamping member 12 and the second clamping member 13, and complete the fine adjustment.

[0051] Further, to improve the structural stability of the adjustment bracket for clamping the ordinary desk top, the present application preferably includes that the second clamping member 13 includes a first clamping layer 131, a second clamping layer 132, and a third clamping layer 133 arranged in sequence from outside to inside; the "from outside to inside" in the present application specifically refers to the side away from the sub-rod 112 to the side close to the sub-rod 112; the third clamping layer 133 is embedded in the second clamping layer 132, and the third clamping layer 133 abuts against the desktop of the ordinary desk to be clamped; the first clamping layer 131 is slidably connected to the second clamping layer 132; the friction force between the first clamping layer 131 and the second clamping layer 132 is less than the friction force between the third clamping layer 133 and the desktop of the ordinary desk to be clamped; the lower end of the first clamping layer 131 is in contact with the lower end of the second clamping layer 132 through an inclined surface 134; the inclined surface 134 gradually approaches the desktop of the ordinary desk to be clamped from top to bottom.

[0052] The included angle between the inclined surface 134 and the vertical surface is 10° to 20°, and preferably, this included angle is 15°.

[0053] In this application, it is preferred that the material of the first clamping layer 131 is metal, the material of the second clamping layer 132 is engineering plastic, and further preferably, this engineering plastic is PC engineering plastic; the material of the third clamping layer 133 is rubber.

[0054] Furthermore, a contact plate 1321 parallel to the upper surface of the tabletop of the ordinary desk to be clamped is provided on the second clamping layer 132, and the contact plate 1321 is in contact with the upper surface of the tabletop of the ordinary desk to be clamped.

[0055] The first clamping layer 131 and the second clamping layer 132 are loosely fitted by rivets. Specifically, in this application, the loose fit means that the first clamping layer 131 and the second clamping layer 132 are connected by rivets, and at the same time, relative sliding can occur between the first clamping layer 131 and the second clamping layer 132.

[0056] Specifically, corresponding through holes are provided on the second clamping layer 132, and the rivets pass through these through holes to be connected to the first clamping layer 131; to achieve loose fit, the inner diameter of the through holes is larger than the outer diameter of the connecting columns on the rivets, so that relative sliding between the first clamping layer 131 and the second clamping layer 132 can only occur in the vertical plane and cannot be separated in other directions, such as the horizontal direction.

[0057] To ensure that relative sliding can occur between the first clamping layer 131 and the second clamping layer 132, through holes with an inner diameter larger than the outer diameter of the adjusting cylinder are also provided on the second clamping layer 132 in this application. After the adjusting cylinder passes through the through holes, while the adjusting bolt 5 is connected to the first clamping layer 131, relative sliding between the first clamping layer 131 and the second clamping layer 132 can occur within a certain range.

[0058] The second clamping member 13 provided in the present application, when an upward pulling force is applied to the adjusting bracket having the second clamping member 13, since the first clamping layer 131 and the second clamping layer 132 are slidably connected through the inclined surface 134, and the frictional force between the first clamping layer 131 and the second clamping layer 132 is less than the frictional force between the third clamping layer 133 and the ordinary desk top to be clamped, at this time, the relative position between the third clamping layer 133 and the ordinary desk top to be clamped remains unchanged, and a sliding trend is generated between the first clamping layer 131 and the second clamping layer 132 at the inclined surface 134, which is distributed along the direction of the inclined surface 134 and points upward from below, that is, a force is generated between the first clamping layer 131 and the second clamping layer 132 at the inclined surface 134, which is distributed along the direction of the inclined surface 134 and points upward from below; since the inclined surface 134 gradually approaches the ordinary desk top to be clamped from top to bottom, the force generated at the inclined surface 134 will generate a component force in the direction pointing to the ordinary desk top to be clamped, so that the force applied by the second clamping member 13 to the ordinary desk top to be clamped is the sum of the pre-tightening force generated by the third clamping layer 133 on the ordinary desk top to be clamped and the component force of the force generated at the inclined surface 134, thereby increasing the connection strength between the second clamping member 13 and the ordinary desk top to be clamped.

[0059] Further, to improve the structural stability of the adjusting bracket, the telescopic connecting member 11 in the present application further includes a sixth support rod 115. The two ends of the sixth support rod 115 are respectively vertically connected to the two mother rods 111. Through the connection of the sixth support rod 115, the adjusting bracket is not easily deformed.

[0060] The angle adjusting structure 2 in the present application includes a fixed support member 21, a rotating support member 22, a diagonal support member 23 and a first adjusting lock 24. The fixed support member 21 is distributed in the horizontal direction, and the fixed support member 21 is fixedly connected to the telescopic connecting member 11; the rotating support member 22 is arranged above the fixed support member 21, and the front end of the rotating support member 22 is rotatably connected to the front end of the fixed support member 21; here, the front end specifically refers to the end close to the user; the first adjusting lock 24 is arranged in the rotating support member 22, the upper end of the diagonal support member 23 is rotatably connected to the first adjusting lock 24, and the first adjusting lock 24 locks the diagonal support member 23 and the rotating support member 22; the lower end of the diagonal support member 23 is rotatably connected to the fixed support member 21.

[0061] Wherein, the diagonal support member 23 and the fixed support member 21, as well as the diagonal support member 23 and the first adjusting lock 24, can be rotatably connected through a pin shaft.

[0062] Specifically, the rotating support member 22 includes two first support rods 221 arranged in parallel, and a second support rod 222 perpendicularly connected to the two first support rods 221. One end of the first support rod 221 is rotatably connected to the fixed support member 21, and the other end is fixedly connected to the second support rod 222. The desktop sliding lock 3 and the first adjustment lock 24 are both arranged in the first support rod 221.

[0063] By providing the second support rod 222, the rotating support member 22 is connected into an integral structure, which is beneficial to improving the structural stability of the rotating support member 22.

[0064] In addition, by arranging both the desktop sliding lock 3 and the first adjustment lock 24 in the first support rod 221, the desktop sliding structure and the angle adjustment structure 2 can be integrally designed, which is beneficial to simplifying the structure of the adjustment bracket.

[0065] To arrange the desktop sliding lock 3 and the first adjustment lock 24 in the first support rod 221 at the same time, see Figure 4 As shown, in this application, the first support rod 221 is provided with a first groove 2211 adapted to the desktop sliding lock 3 and a second groove 2212 adapted to the first adjustment lock 24. The first groove 2211 is arranged inside the second groove 2212, and the opening direction of the first groove 2211 is upward, and the opening direction of the second groove 2212 is downward.

[0066] The desktop sliding lock 3 is arranged in the first groove 2211 with an upward opening. By adjusting the position of the desktop sliding lock 3 in the first groove 2211, the position of the learning desktop 4 is adjusted.

[0067] In this application, the first support rod 221 is arranged in a structural form in which two grooves with opposite opening directions are connected, so that the first support rod 221 can serve two purposes, which is beneficial to simplifying the structure of the adjustment bracket. At the same time, through the first support rod 221, the desktop sliding structure and the angle adjustment structure 2 are integrally designed, so that during use, the position of the learning desktop 4 can be adjusted through the cooperation of the desktop sliding structure and the angle adjustment structure 2, so that the learning desktop 4 can meet various usage requirements of users.

[0068] In addition, by arranging both the desktop sliding lock 3 and the first adjustment lock 24 on the first support rod 221, when adjusting the position of the study desktop 4, the study desktop 4 can first be adjusted to a certain inclination angle through the first adjustment lock 24, and then the position of the study desktop 4 in the front-back direction can be adjusted through the desktop sliding lock 3. The study desktop 4 can also be adjusted to be closer to the user side than the desktop of a common desk connected by the adjustment bracket. Thus, through the synergistic effect of the desktop sliding structure and the angle adjustment structure 2, the adjustment range of the adjustment bracket is further expanded, its usage range is enlarged, and the usage comfort is improved.

[0069] Specifically, the upper part of the desktop sliding lock 3 is connected to the study desktop 4. This connection method can be welding, snap connection, etc. In this application, it is preferably that the desktop sliding lock 3 is connected to the study desktop 4 through fasteners.

[0070] When adjusting the angle of the study desktop 4, the first adjustment lock 24 is unlocked, so that the connection relationship between the first adjustment lock 24 and the first support rod 221 is released. At this time, the first adjustment lock 24 can slide in the second groove 2212, so that the connection relationship between the diagonal brace 23 and the first support rod 221 is a sliding connection; since both ends of the diagonal brace 23 are respectively rotatably connected to the fixed support 21 and the first adjustment lock 24, and the position of the fixed support 21 remains unchanged, the connection position between the diagonal brace 23 and the fixed support 21 remains unchanged. As the first adjustment lock 24 slides, the position of the end of the diagonal brace 23 connected to the first adjustment lock 24 changes. Therefore, the inclination angle of the diagonal brace 23 changes. At the same time, the inclination angle of the first support rod 221 changes, driving the inclination angle of the study desktop 4 connected to the first support rod 221 to change; when the inclination angle of the study desktop 4 meets the usage requirements, the first adjustment lock 24 is locked, so that the first adjustment lock 24 is fixed to the first support rod 221. The inclination angles of the diagonal brace 23 and the first support rod 221 both remain unchanged, thereby realizing the fixation of the position of the study desktop 4.

[0071] The desktop sliding lock 3 can be an adjustment lock structure of any structural form; see Figure 5 As shown, in this application, it is preferably that the desktop sliding lock 3 includes a positioning protrusion 31, an adjustment structure 32 for driving the positioning protrusion 31 to move up and down, and a sliding switch 33 connected to the adjustment structure 32; a plurality of positioning holes (not shown in the figure) adapted to the positioning protrusion 31 are provided at the bottom of the first groove 2211. By inserting the positioning protrusion 31 into the positioning holes, the locking of the desktop sliding lock 3 is realized.
