Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustable desk technology, specifically to an angle adjustment and fixing mechanism and a desk. Background Technology
[0002] Traditional study desks typically maintain a fixed horizontal surface, making it difficult to adapt to diverse learning needs. To address this, the current solution involves symmetrically placing hydraulic rods on both sides of the desk frame, combined with a hinge structure, to allow the desk surface to flexibly transition from a horizontal to a sloping position. Specifically, users can easily adjust the desktop to the desired tilt angle by controlling the extension and retraction of the hydraulic rods, finding the most comfortable working posture for drawing, reading, or other learning activities. This design not only greatly enriches the functionality of the study desk but also meets diverse learning needs.
[0003] However, the above technical solutions also have certain limitations and potential problems. First, the maintenance of hydraulic systems is relatively complex, requiring regular inspection and maintenance to ensure their normal operation. Second, there are issues with the reliability and stability of the adjustment function. Especially for children, operating the hydraulic lever to adjust the desktop angle may require a period of learning and adaptation, increasing the difficulty of use and lowering safety. Furthermore, even after the angle adjustment is completed, the stability of the desktop remains poor.
[0004] Therefore, in practical applications, this application, by comprehensively considering these factors and continuously optimizing the design, aims to improve the user experience and market competitiveness of the product by designing a table angle adjustment fixing mechanism and table.

[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide an angle adjustment and fixing mechanism that is not only simple in structure but also convenient to install and operate. It provides better safety performance while offering stability, making it suitable for different groups of people.
[0006] The technical solutions adopted in this utility model are as follows:
[0007] An angle adjustment and fixing mechanism, characterized in that it comprises:
[0008] A fastener has a through hole on one side and a fusion cavity inside, with the through hole communicating with the fusion cavity to form a locking groove.
[0009] A first abutting surface is provided inside the fusion cavity. The top end of the first abutting surface extends upward towards the through hole to form a second abutting surface. The top end of the second abutting surface extends downward towards the through hole to form a third abutting surface. A locking angle is formed between the second abutting surface and the third abutting surface.
[0010] A control component, the control component including a control part and a locking part, one end of the locking part being connected to the control part, and the other end being provided with a protruding latch;
[0011] In use, the locking part is placed into the locking groove, and the control part is rotated to make the locking block engage with the locking angle and be in a locked state, and the locking block disengages from the locking angle and is in an unlocked state.
[0012] In another embodiment, preferably, the bottom end of the first abutting surface extends horizontally toward the through hole to form a first free surface, the first free surface extends obliquely upward along the through hole to form a second free surface, and the second free surface extends horizontally to form a third free surface;
[0013] A slider is provided on the locking part, and the slider is disposed on the surface of the locking part near the side of the locking block;
[0014] When the locking part is placed into the locking groove, the slider is slidably connected to the upper surface of the third free surface.
[0015] In another embodiment, preferably, a support block is provided on the surface of the control member, the support block extends to the surface of the control member and is located at the connection between the control part and the locking part;
[0016] When the locking part is inserted into the lock groove, the support block is located outside the lock groove.
[0017] In another embodiment, preferably, the bottom end of the third abutment surface extends upward at an angle toward the through hole to form a fourth abutment surface, the fourth abutment surface being used to limit the rotation angle of the control member.
[0018] In another embodiment, preferably, the angle of the locking angle is between 15° and 30°.
[0019] In another embodiment, preferably, it further includes a housing comprising two parallel mounting plates and a top plate connecting the two mounting plates, the housing being fitted over the outside of the fastener.
[0020] In another embodiment, preferably, the fastener is fixedly connected to the housing;
[0021] The control component is rotatably connected to the housing via a rotating shaft, which passes through the locking part and is connected at both ends to the two mounting plates respectively.
[0022] In another embodiment, preferably, a torsion spring is sleeved on the rotating shaft, the torsion spring being located in the locking part and fixedly connected to the end of the locking part.
[0023] When unlocked, the top surface of the control unit is in close contact with the top plate; when locked, the top surface of the control unit is away from the top plate.
[0024] A table, characterized in that it comprises:
[0025] The desktop has an angle adjustment and fixing mechanism provided on each of the two sides corresponding to the bottom surface of the desktop. The angle adjustment and fixing mechanism is one of the angle adjustment and fixing mechanisms described above.
[0026] The fixing component of the angle adjustment fixing mechanism is connected to the support component of the desktop.
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] 1. The angle adjustment and fixing mechanism in this utility model uses a locking groove on a fixing member and a cooperating control member to coordinate the two. When the control unit rotates, the locking block engages with the locking angle to lock it in the locked state, and the locking block disengages from the locking angle to unlock it. This simply achieves direct switching between the unlocked and locked states.
[0029] 2. This utility model cleverly reduces the difficulty of operation and improves stability through the unique design of the fusion cavity structure and the structure of the corresponding control components.
[0030] 3. In this utility model, by providing a support block on the surface of the control component, the support block is located outside the locking groove during use. This improves the stability of both components while enabling the control component to control the locking part to rotate within the fusion cavity.
[0031] 4. The housing in this utility model not only protects the fixing and control components, but also facilitates connection and fixation to the desktop.
[0032] In this invention, a torsion spring is fitted onto the connecting shaft. The torsion force of the torsion spring drives the switch, allowing the locking part to stably switch between locked and unlocked states. Simultaneously, the locking angle is set between 15° and 30° to utilize the force generated by the angle, further enhancing the locking effect. This prevents the locking block from slipping out from the locking angle after fixing, improving stability and thus ensuring safety.
[0033] In summary, this utility model is ingeniously designed and has a reasonable structure, which can effectively and stably fix the desktop after the angle is adjusted. It has significant promotional value due to its simple operation and high safety. Attached Figure Description

[0057] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0058] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0059] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0060] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0061] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0062] In an embodiment of the angle adjustment and fixing mechanism of this utility model, see... Figure 1-10 As shown, specifically, it includes a fixing member 100, with a through hole 101 on one side of the fixing member 100, and a fusion cavity 102 provided inside the fixing member 100, with the through hole 101 communicating with the fusion cavity 102 to form a locking groove 103. See also... Figure 9 As shown, the structure of the fusion cavity 102 specifically includes a first abutment surface 1021. The top end of the first abutment surface 1021 extends upwards towards the through hole 101 to form a second abutment surface 1022. The top end of the second abutment surface 1022 extends downwards towards the through hole 101 to form a third abutment surface 1023. The second abutment surface 1022 and the third abutment surface 1023 form a locking angle β. In addition, see... Figure 10 As shown, it also includes a control component 200. Specifically, the control component 200 includes a control part 201 and a locking part 202. One end of the locking part 202 is connected to the control part 201, and the other end is provided with a protruding locking block 203. In use, the locking part 202 is placed into the locking groove 103, and the control part 201 is rotated to make the locking block 203 engage with the locking angle β and be in a locked state. When the locking block 203 disengages from the locking angle β, it is in an unlocked state.
[0063] In another embodiment of this application, see Figure 7-9 As shown, a further improvement is made based on the above embodiment, wherein the improvement is as follows: the bottom end of the first abutting surface 1021 extends horizontally toward the through hole 101 to form a first free surface 1025; the first free surface 1025 extends obliquely upward along the through hole 101 to form a second free surface 1026; the second free surface 1026 extends horizontally to form a third free surface 1027; see Figure 10 As shown, a slider 2021 is also provided on the locking part 202. The slider 2021 is provided on the surface of the locking part 202 near the side of the latch block 203. In actual installation, a protrusion can be provided on the surface of the locking part 202. Figure 6 As shown, when the locking part 202 is placed into the locking groove 103, the slider 2021 is slidably connected to the upper surface of the third free surface 1027. From Figure 5 As shown, the sliding distance of the slider 2021 is determined by the horizontal width of the third free surface 1027, mainly to prevent the control component 200 from falling off when it rotates.
[0064] In another embodiment of this application, see Figure 10 As shown, a further improvement is made based on the above embodiment, wherein a support block 2011 is further provided on the surface of the control member 200. In actual installation, the support block 2011 extends from the surface of the control member 200 and is located at the connection between the control part 201 and the locking part 202. Figure 6 As shown, when the locking part 202 is placed into the locking groove 103, the support block 2011 is located outside the locking groove 103 and outside the hole wall of the through hole 101 of the fixing member 100. This arrangement not only limits the angle during rotation, but also allows the hole wall of the through hole 101 to provide support for the control member 200, further ensuring the stability of the connection between the two.
[0065] In another embodiment of this application, see again Figure 9 As shown, a further improvement is made based on the above embodiment, and the improvement is that the bottom end of the third abutment surface 1023 is inclined upward towards the through hole 101 to obtain the fourth abutment surface 1024. In this embodiment, the fourth abutment surface 1024 is set as an upward curved arc surface, mainly to limit the rotation angle of the control component 200, while ensuring the smoothness of the rotation of the control component 200 and avoiding the phenomenon of jamming when the rotation position of the control component 200 is blocked during operation.
[0066] In the above embodiments, it should be noted that the locking angle β in this application is set between 15° and 30°. This allows the force generated by the angle to further enhance the locking effect, providing a tighter connection between the locking block 203 and the second and third contact surfaces, improving stability and ensuring security. Of course, other angles can be selected in other embodiments, but 30° is preferred as the optimal operating angle in this application. See details... Figure 6 As shown.
[0067] Meanwhile, in actual use, refer to the above embodiments. Figure 1-3 As shown, a housing 300 is further provided, which includes two parallel mounting plates 301 and a top plate 302 connecting the two mounting plates 301. In actual use, the housing 300 is fitted over the outside of the fixing member 100, which not only provides protection but also secures the entire component. The fixing member 100 and the housing 300 are fixedly connected by fixing bolts, while the control member 200 is mainly rotatably connected to the housing 300 by a rotating shaft 400. The rotating shaft 400 passes through the locking part 202 and its two ends are connected to the two mounting plates 301 respectively.
[0068] In another embodiment of this utility model, the stability of the entire angle adjustment and fixing mechanism is further improved, see... Figure 10 As shown, in actual use, a torsion spring 500 is fitted onto the rotating shaft 400, and the torsion spring 500 is located in the locking part 202 and fixedly connected to the end of the locking part 202. In this way, in the unlocked state, the top surface of the control part 201 is in close contact with the top plate 302; in the locked state, the top surface of the control part 201 is away from the top plate 302. This design is not only simple in structure but also convenient in operation.
[0069] This utility model also provides a table, specifically including a tabletop, with an angle adjustment and fixing mechanism provided on each of the two sides corresponding to the bottom surface of the tabletop. This angle adjustment and fixing mechanism is connected to any of the angle adjustment and fixing mechanisms described in the above embodiments. The fixing member 100 of the angle adjustment and fixing mechanism is connected to the support member of the tabletop, i.e., connected to a table leg. Thus, when the angle adjustment and fixing mechanism is in the unlocked state, rotating the tabletop will cause the angle adjustment and fixing mechanism to automatically lock under the action of the torsion spring 500 after the tabletop has rotated to the desired angle. For further adjustment, the control unit 201 needs to be rotated to unlock it again.
[0070] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
