Description

Technical Field

[0001] This utility model relates to the technical field of office desks, and more specifically, to a quick-release structure and an office desk. Background Technology

[0002] Currently, office desks are widely used in offices and homes due to their height-adjustable function. Their core load-bearing component is the desk frame, which needs to be assembled with supporting legs, crossbeams, desktop connectors, and other accessories to form a complete structure. The current assembly method for office desk frames generally adopts an "on-site alignment / screw fixing" mode: the operator must first align the accessories to be assembled (such as supporting legs and crossbeams) with the preset connection points on the main body of the desk frame, then manually locate the screw holes on the desk frame or accessories, and finally insert the screws into the holes and tighten them to secure them. Deficiencies of existing technology Screw hole positioning is difficult: The screw holes of the office desk frame and accessories are mostly located on the connecting end face or side face of the components. During assembly, they are easily affected by factors such as the weight of the components, the obstruction of the assembly space, and the deviation of the line of sight. Operators have difficulty finding the screw hole position quickly and accurately, and need to repeatedly adjust the angle and position of the components for calibration, which significantly prolongs the assembly time. High operational threshold: This assembly method requires a high level of experience and precision from the operator. Non-professional users (such as consumers who install it themselves at home) are prone to problems such as misaligned screw holes and screws not being able to be inserted smoothly. In fact, forced alignment may even cause damage to the table frame or accessory structure. The assembly process is fragmented: In the traditional method, screws and parts to be assembled need to be picked up and handled in separate steps, which not only increases the number of steps, but also poses a risk of screws being lost during the assembly process, further reducing assembly efficiency and integrity. As the demand for "easy installation" in the office desk market increases, the existing assembly method that relies on "finding holes on-site" can no longer meet users' needs for efficient and low-barrier disassembly and assembly. Therefore, there is an urgent need for an office desk frame assembly structure that can solve the problem of screw hole positioning and simplify the assembly process, so as to improve disassembly and assembly efficiency, lower the operation threshold, and adapt to large-scale production and end-user self-installation scenarios. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release structure and office desk to solve the technical problems of difficult screw hole positioning, high operation threshold and fragmented assembly process in the existing technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, a quick-release structure is provided, including: The first component is provided with a sliding groove, the sliding groove including a first sliding groove section and a second sliding groove section communicating with the first sliding groove section, the first sliding groove section being provided with a groove opening; The second component is provided with a fastener that can slide and engage with the slide groove. The fastener is threadedly connected to the second component. The second component can drive the fastener from the slot into the first slide groove section and into the second slide groove section. The fastener can lock the second component and the first component in the second slide groove section.

[0005] This structure eliminates the need to locate screw holes on-site during assembly. The guide effect of the sliding groove ensures precise alignment of fasteners, significantly simplifying the assembly process and reducing the requirements for operator experience and precision. It effectively avoids assembly errors or structural damage caused by non-professional users' difficulty in alignment. At the same time, the fasteners always maintain an assembly association with the second component, reducing the risk of fastener loss during assembly and significantly improving disassembly and assembly efficiency. It is well-suited for large-scale production scenarios of lifting table frames as well as end-user self-installation scenarios, meeting the market demand for convenient installation of lifting table frames.

[0006] In one embodiment, the fastener includes a threaded portion, a sliding portion connected to the threaded portion, and a fastening portion connected to the sliding portion. The threaded portion is threadedly connected to the second component to drive the fastening portion to move axially in the fastener, so that the fastening portion can fasten the first component and the second component. In the axial direction of the fastener, the projection size of the fastening portion is larger than the projection size of the sliding portion, and the sliding portion is used to slide in connection with the first slide section and the second slide section.

[0007] In one embodiment, the second component is provided with a recessed section communicating with the second slide section. The recessed section is located in the depth direction of the second slide section. The fastening part can be inserted into the recessed section under the drive of the threaded part, so that the surface of the fastening part is flush with the surface of the second component.

[0008] In one embodiment, the first chute segment and the second chute segment constitute a gourd-shaped chute structure; or, the chute length direction of the first chute segment is perpendicular to the chute length direction of the second chute segment; or, the chute length direction of the first chute segment is parallel to the chute length direction of the second chute segment; or, the chute length direction of the first chute segment forms a preset angle with the chute length direction of the second chute segment.

[0009] In one embodiment, when the groove length direction of the first chute segment forms a preset angle with the groove length direction of the second chute segment, the preset angle ranges from 90° to 180°.

[0010] In one embodiment, when the first component is a support leg and the second component is a support column, the first slide section and the second slide section form a gourd-shaped groove structure; when the first component is a longitudinal frame and the second component is a transverse frame, the groove length direction of the first slide section is perpendicular to the groove length direction of the second slide section; when the first component is a transverse frame and the second component is a motor box frame, there are two slides and two fasteners. The two fasteners are placed into the corresponding slides in sequence. The groove length direction of the first slide section of one slide is parallel to the groove length direction of the second slide section, and the groove length direction of the first slide section of the other slide forms a preset angle with the groove length direction of the second slide section, the preset angle ranging from 90° to 180°.

[0011] In one embodiment, when the first component is a horizontal frame, the first component is provided with operation holes corresponding one-to-one with the slide groove for inserting fastening tools.

[0012] In one embodiment, when the second component is a horizontal frame, the second component is provided with a hook fixing claw for fixing a hook. The hook fixing claw is arranged vertically upward, and the hook is provided with a fixing hole that mates with the hook fixing claw. The hook is fixedly connected to the hook fixing claw by its own weight. In one embodiment, when the first component is a horizontal frame, the horizontal frame includes two first frames and a second frame connecting the two first frames. The second frame is connected to the first frame by bolts.

[0013] Secondly, an office desk is provided, including an office desk frame, an office desk panel, and the aforementioned quick-release structure, wherein the office desk panel is disposed on the office desk frame, and the quick-release structure is applied to the office desk frame.

[0014] By adopting the above technical solution, the aforementioned quick-release structure is integrated into the desk frame and combined with the desk board to form a complete desk. This can significantly improve assembly efficiency to meet the needs of end users for self-installation and rapid layout in the office space. It can also ensure the structural stability of the tightly connected parts of the desk frame to meet daily load-bearing and durability requirements. Furthermore, it can optimize the transportation and storage experience after disassembling the desk frame parts to reduce costs and damage risks. It can also improve versatility and ease of maintenance to reduce production mold costs and waste of later maintenance resources. In addition, it can enhance the flexibility of use to adapt to the needs of office space adjustment and functional upgrade. Attached Figure Description

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be located directly on or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

They are only for the convenience of describing this utility model and do not indicate that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments: like Figures 1 to 3 As shown, an embodiment of this utility model provides a quick-release structure, comprising: Please refer to the following: Figure 4 The first component 1 is provided with a slide groove 11, which includes a first slide groove section 111 and a second slide groove section 112 communicating with the first slide groove section 111. The first slide groove section 111 is provided with a groove opening 113. The second component 2 is provided with a fastener 3 that can slide and engage with the slide groove 11. The fastener 3 is threadedly connected to the second component 2. The second component 2 can drive the fastener 3 from the slot 113 into the first slide groove section 111 and into the second slide groove section 112. The fastener 3 can lock the second component 2 and the first component 1 in the second slide groove section 112.

[0029] The quick-release structure comprises a first component 1 and a second component 2. The first component 1 is provided with a sliding groove 11, which specifically includes a first sliding groove section 111 and a second sliding groove section 112 that is in communication with the first sliding groove section 111. The first sliding groove section 111 is provided with a slot 113. The second component 2 is provided with a fastener 3 that can slide with the sliding groove 11. The fastener 3 and the second component 2 are assembled by a threaded connection.

[0030] Its working principle is that the second component 2 can drive the fastener 3 from the slot 113 of the first slide section 111 into the interior of the first slide section 111. Then the fastener 3 continues to slide with the second component 2 and enters the second slide section 112 which is connected to the first slide section 111. When the fastener 3 slides to the corresponding position in the second slide section 112, the fastener 3 can be locked by means of the thread engagement between the fastener 3 and the second component 2. Through this locking operation, the second component 2 and the first component 1 can form a stable connection relationship.

[0031] From a technical perspective, this structure eliminates the need to locate screw holes on-site during assembly. The guide function of the slide groove 11 ensures precise alignment of the fastener 3, significantly simplifying the assembly process and reducing the requirements for operator experience and precision. This effectively avoids assembly errors or structural damage caused by alignment difficulties for non-professional users. At the same time, the fastener 3 remains consistently associated with the second component 2, reducing the risk of fastener 3 being lost during assembly and significantly improving disassembly and assembly efficiency. It is well-suited for large-scale production of lifting table frames and self-installation scenarios by end users, meeting the market demand for convenient installation of lifting table frames.

[0032] like Figure 5 As shown, in one embodiment, the fastener 3 includes a threaded portion 31, a sliding portion 32 connected to the threaded portion 31, and a fastening portion 33 connected to the sliding portion 32. The threaded portion 31 is threadedly connected to the second component 2 to drive the fastening portion 33 to move in the axial direction of the fastener 3, so that the fastening portion 33 can fasten the first component 1 and the second component 2. In the axial direction of the fastener 3, the projection size of the fastening portion 33 is larger than the projection size of the sliding portion 32. The sliding portion 32 is used to slide in connection with the first slide groove section 111 and the second slide groove section 112.

[0033] The fastener 3 in the quick-release structure includes a threaded part 31, a sliding part 32, and a fastening part 33. One end of the sliding part 32 is connected to the threaded part 31, and the other end is connected to the fastening part 33. The threaded part 31 forms a threaded connection with the second component 2. In the axial direction of the fastener 3, the projected size of the fastening part 33 is larger than the projected size of the sliding part 32. The sliding part 32 is used to achieve a sliding connection with the first sliding groove section 111 and the second sliding groove section 112 on the first component 1. Its working principle is as follows: when the second component 2 drives the fastener 3 to enter from the slot 113 of the first slide section 111, the sliding part 32 slides along the first slide section 111 to the position communicating with the second slide section 112. It continues to slide so that the sliding part 32 enters the second slide section 112. At this time, by rotating the threaded part 31, the threaded engagement relationship between the threaded part 31 and the second component 2 is used to drive the fastening part 33 to move in the axial direction of the fastener 3. Since the projected surface size of the fastening part 33 is larger than that of the sliding part 32, as the fastening part 33 moves axially, it can form a pressing action with the surface of the first component 1, thereby realizing the fastening connection between the second component 2 and the first component 1. By adopting the above technical solution, the fastener 3 structure, through the matching design of the sliding part 32 and the sliding groove 11, ensures the precise guidance of the fastener 3 during the assembly process, avoids the tedious operation of finding screw holes in the prior art, greatly reduces the assembly difficulty, and allows non-professional users to complete the operation quickly. At the same time, the pre-connection relationship between the threaded part 31 and the second component 2 ensures that the fastener 3 will not be lost during the assembly process, ensuring the integrity and efficiency of the assembly. Furthermore, the fastening part 33 achieves tight fixation through axial movement, which has stronger connection stability compared to the traditional screw through-hole fixing method. It can better adapt to the load borne by the lifting table frame during use, meet the dual needs of large-scale production and end-user self-installation, and effectively solve the defects of the existing lifting table frame assembly structure.

[0034] In one embodiment, the second component 2 is provided with a recessed section 114 that communicates with the second slide section 112. The recessed section 114 is located in the depth direction X of the second slide section 112. The fastening part 33 can be inserted into the recessed section 114 under the drive of the threaded part 31, so that the surface of the fastening part 33 is flush with the surface of the second component 2.

[0035] Specifically, in the structure of this quick-release structure, the second component 2 is further provided with a recessed section 114. The recessed section 114 is in communication with the second sliding section 112 on the second component 2, and the recessed section 114 is located in the depth direction X of the second sliding section 112. At the same time, combined with the structural design of the fastener 3, the size and shape of the recessed section 114 are adapted to the fastening part 33 of the fastener 3, so that the fastening part 33 can enter and be placed inside the recessed section 114 under the drive of the threaded part 31. When the fastening part 33 is completely placed into the recessed section 114, the surface of the fastening part 33 can be kept flush with the surface of the second component 2.

[0036] Its working principle is as follows: During assembly, the axial direction of the fastener 3 is parallel to the depth direction X of the slide groove. After the second component 2 drives the sliding part 32 of the fastener 3 to slide into the second slide groove section 112 along the first slide groove section 111, the operator rotates the threaded part 31 of the fastener 3. The threaded engagement between the threaded part 31 and the second component 2 drives the fastening part 33 to move along the axial direction of the fastener 3 towards the recessed section 114. As the fastening part 33 continues to move, it gradually enters the recessed section 114 located in the depth direction X of the second slide groove section 112 until the fastening part 33 is completely inserted into the recessed section 114. At this time, the surface of the fastening part 33 is flush with the surface of the second component 2. At the same time, under the locking action of the threaded engagement, the fastening part 33 and the inner wall of the recessed section 114 form a tight fit, further strengthening the connection stability between the second component 2 and the first component 1.

[0037] By adopting the above technical solution, on the one hand, the design of the recessed section 114 can accommodate and limit the fastener 33, preventing the fastener 33 from protruding from the surface of the second component 2 after locking. This not only improves the neatness of the assembled height-adjustable desk frame, but also prevents the protruding fastener 33 from bumping into the user or other items during use, reducing safety hazards. On the other hand, the flush setting of the fastener 33 after being placed into the recessed section 114 can reduce the impact or wear of the fastener 33 during use, extending the service life of the fastener 3. At the same time, in conjunction with the guiding assembly of the sliding part 32 and the sliding groove 11, the advantage of the overall quick-release structure that does not require on-site hole finding is continued. On the basis of simplifying the assembly process and lowering the operation threshold, the stability and practicality of the connection structure are further improved, making it more suitable for the long-term use needs of the height-adjustable desk frame in office, home and other scenarios. like Figure 4 As shown, in one embodiment, the first slide section 111 and the second slide section 112 constitute a gourd-shaped groove structure; or, as... Figure 6 As shown, the groove length direction of the first slide section 111 is perpendicular to the groove length direction of the second slide section 112; or, as... Figure 7 As shown, the groove length direction of the first slide section 111 is parallel to the groove length direction of the second slide section 112; or, the groove length direction of the first slide section 111 and the groove length direction of the second slide section 112 form a preset angle, the preset angle range being 90° to 180°.

[0038] Specifically, in the structure of this quick-release structure, the slide groove 11 on the first component 1 is composed of a first slide groove segment 111 and a second slide groove segment 112, and there are four specific structural forms. The first form is that the first slide groove segment 111 and the second slide groove segment 112 together form a gourd-shaped groove structure. In this structure, the connection between the first slide groove segment 111 and the second slide groove segment 112 forms a constricted design to limit the sliding part 32 of the fastener 3. The second form is that the groove length direction of the first slide groove segment 111 is perpendicular to the groove length direction of the second slide groove segment 112, and the two slide groove segments 11 are connected at a right angle. The third form is that the groove length direction of the first slide groove segment 111 is parallel to the groove length direction of the second slide groove segment 112, and the two slide groove segments 11 extend in the same direction and remain connected. The fourth form is that the groove length direction of the first slide groove segment 111 and the groove length direction of the second slide groove segment 112 form a preset angle, and the preset angle is limited to 90°. Between 180° and 180°, the two slide grooves 11 segments are connected at corresponding angles. At the same time, in the four structural forms, the first slide groove segment 111 is provided with a groove 113 and the size of each slide groove segment 11 is adapted to the sliding part 32 of the fastener 3, ensuring that the sliding part 32 can slide smoothly in the slide groove segment 11.

[0039] Its working principle is as follows: After the second component 2 drives the sliding part 32 of the fastener 3 to enter from the groove 113 of the first slide section 111, if it is a gourd-shaped groove structure, the sliding part 32 slides along the first slide section 111 to the closing point that communicates with the second slide section 112 and then enters the second slide section 112 and is limited by the closing point. If it is a structure with the groove length direction perpendicular, the sliding part 32 slides along the first slide section 111 to the end and then turns to the vertical direction to enter the second slide section 112. If it is a structure with the groove length direction parallel... The sliding part 32 slides straight along the first slide section 111 into the parallel second slide section 112. If it is a structure with a preset angle, the sliding part 32 slides along the first slide section 111 to the angle connection point and then enters the second slide section 112 at the preset angle. After the sliding part 32 enters the designated position of the second slide section 112, the fastening part 33 is driven to move axially by rotating the threaded part 31 of the fastener 3, so that the fastening part 33 abuts against the first component 1 and locks the second component 2 and the first component 1.

[0040] By adopting the above technical solutions, the four types of 11-segment sliding groove structures can be adapted to the assembly requirements of different parts of the lifting table frame. The gourd-shaped groove structure can use the tapering design to prevent the fastener 3 from accidentally sliding out of the first sliding groove segment 111 during use, thus improving connection stability. The structure with the vertical groove length direction can adapt to the installation space of the right-angle connection part of the table frame. The structure with the parallel groove length direction can shorten the sliding path and improve assembly efficiency. The structure with a preset included angle of 90° to 180° can flexibly adapt to the non-right-angle and non-parallel irregular connection structure of the table frame. All four forms continue the advantages of the sliding groove 11 guiding assembly, eliminating the need to find screw holes on site, further expanding the adaptability range of the quick-release structure in different structural parts of the lifting table frame, while ensuring the ease of assembly and connection reliability in various scenarios, meeting the diverse structural design requirements of the lifting table frame and the efficiency and stability requirements in different production and installation scenarios.

[0041] In one embodiment, when the first component 1 is a support leg 10 and the second component 2 is a support column 20, the first slide section 111 and the second slide section 112 form a gourd-shaped trough structure; when the first component 1 is a longitudinal frame 30 and the second component 2 is a transverse frame 50, the groove length direction of the first slide section 111 is perpendicular to the groove length direction of the second slide section 112; when the first component 1 is a transverse frame 50 and the second component 2 is a motor box frame 40, there are two slides 11 and two fasteners 3. The two fasteners 3 are placed into the corresponding slides 11 in sequence. The groove length direction of the first slide section 111 of one slide 11 is parallel to the groove length direction of the second slide section 112, and the groove length direction of the first slide section 111 of the other slide 11 forms a preset angle with the groove length direction of the second slide section 112. The preset angle range is 90° to 180°.

[0042] Specifically, in one embodiment of the quick-release structure, three different sliding groove 11 schemes are designed for different component combinations of the office desk frame. When the first component 1 is the support leg 10 of the office desk frame and the second component 2 is the support column 20 of the office desk frame, the sliding groove 11 on the first component 1, i.e., the support leg 10, is composed of a first sliding groove section 111 and a second sliding groove section 112 forming a gourd-shaped groove structure. The first sliding groove section 111 is provided with a slot 113 for the fastener 3 to enter, and the connection of the gourd-shaped groove structure forms a constricted design. The overall size of the sliding groove 11 is adapted to the sliding part 32 of the fastener 3. When the first component 1 is the longitudinal frame 30 of the office desk frame and the second component 2 is the transverse frame 50 of the office desk frame, the sliding groove 11 on the first component 1, i.e., the longitudinal frame 30, is composed of a first sliding groove section 111 and a second sliding groove section 112. The first slide section 111 has its groove length direction perpendicular to the groove length direction of the second slide section 112. The two slide sections 11 are connected at right angles, and the first slide section 111 also has a groove 113. The size of the slide section 11 is adapted to the sliding part 32 of the fastener 3. When the first component 1 is the horizontal frame 50 of the office desk frame and the second component 2 is the motor box frame 40 of the office desk frame, the first component 1, i.e., the horizontal frame 50, has two slide sections 11, and the second component 2, i.e., the motor box frame 40, has two fasteners 3. The first slide section 111 of one slide section 11 has its groove length direction parallel to the groove length direction of the second slide section 112, and the first slide section 111 of the other slide section 11 forms a preset angle with the groove length direction of the second slide section 112, and the preset angle ranges from 90°. Up to 180°, the first slide section 111 of both slides 11 is provided with a groove 113 and the size of each slide 11 is adapted to the sliding part 32 of the corresponding fastener 3.

[0043] Its working principle is as follows: Regarding the cooperation between the support leg 10 and the support column 20, the second component 2, i.e., the support column 20, drives the sliding part 32 of the fastener 3 to enter from the first slide groove 111 opening 113 of the first component 1, i.e., the support leg 10. It slides along the first slide groove 111 to the end, where it connects with the second slide groove 112, and then enters the second slide groove 112. The closing structure of the gourd groove limits the sliding part 32. Regarding the cooperation between the longitudinal frame 30 and the transverse frame 50, the second component 2, i.e., the transverse frame 50, drives the sliding part 32 of the fastener 3 to enter from the first slide groove 111 opening 113 of the first component 1, i.e., the longitudinal frame 30. It slides along the first slide groove 111 to the end and then turns vertically to enter the second slide groove 112. Regarding the cooperation between the transverse frame 50 and the motor box frame 40... In sequence, the second component 2, namely the motor box frame 40, first drives the sliding part 32 of the first fastener 3 to enter from the slot 113 of the first slide groove 11 and slide along it to the parallel second slide groove 112. Then, it drives the sliding part 32 of the second fastener 3 to enter from the slot 113 of the first slide groove 11 and slide along it to the second slide groove 112 at a preset angle. After all the sliding parts 32 of the fasteners 3 have entered the designated positions of the corresponding second slide groove 112, the threaded part 31 of the fastener 3 is rotated to drive the fastening part 33 to move along the axial direction of the fastener 3 towards the first component 1, so that the fastening part 33 abuts against the surface of the first component 1, thereby achieving a stable locking connection between the second component 2 and the first component 1.

[0044] By adopting the above technical solutions, the three types of slide groove 11 can accurately match the vertical support connection between the desk frame support leg 10 and support column 20, the right-angle frame connection between the longitudinal frame 30 and the transverse frame 50, and the drive component connection requirements between the transverse frame 50 and the motor box frame 40. The gourd-shaped groove structure of the support leg 10 and support column 20, with its tapered design, prevents the fastener 3 from accidentally falling off, improving the bottom support stability of the desk frame. The vertical slide groove 11 structure of the longitudinal frame 30 and transverse frame 50 adapts to the spatial layout of the right-angle frame connection, solving the orientation alignment problem during assembly. The double slide groove 11 and double fastener 3 design of the transverse frame 50 and motor box frame 40 enhances the connection strength through the combination of parallel slide groove 11 and angled slide groove 11 and the sequential assembly order, from 90° to 180°. The preset angle can also adapt to non-right-angle irregular connection scenarios; all solutions continue the advantage of the slide 11 guide assembly that does not require on-site hole finding, which greatly reduces the assembly difficulty of each component of the office desk frame, covering the entire process from frame construction to drive component installation, and meeting the dual needs of large-scale production of office desks and self-assembly by end users.

[0045] In one embodiment, when the first component 1 is a horizontal frame 50, the first component 1 is provided with an operation hole 12 corresponding to the slide groove 11 for inserting a fastening tool.

[0046] Specifically, in the structure of this quick-release structure, when the first component 1 is the horizontal frame 50 of the office desk frame, and considering the scenario where the horizontal frame 50 and the second component 2, i.e. the motor box frame 40, are equipped with two sliding grooves 11, the first component 1, i.e. the horizontal frame 50, is provided with operating holes 12 that correspond one-to-one with the two sliding grooves 11. The operating holes 12 are located at the preset positions on the horizontal frame 50 corresponding to the sliding grooves 11 and penetrate the wall of the horizontal frame 50. The diameter of the operating holes 12 is adapted to the insertion of common fastening tools, and the depth ensures that the fastening tool can reach the threaded part 31 of the fastener 3 in the corresponding sliding groove 11 after insertion. At the same time, the position of the operating holes 12 avoids the sliding path of the sliding part 32 of the fastener 3 in the sliding groove 11, so as not to affect the normal sliding of the sliding part 32 between the first sliding groove section 111 and the second sliding groove section 112. Furthermore, the edge of the operating holes 12 has no protruding structure to avoid interfering with the operation of the tools.

[0047] Its working principle is as follows: After the second component 2, namely the motor box frame 40, drives the sliding parts 32 of the two fasteners 3 to enter the designated positions of the second slide groove section 112 of the corresponding slide groove 11 on the transverse frame 50 in sequence, the operator inserts the fastening tool into the operating hole 12 on the transverse frame 50 that corresponds to the slide groove 11, so that the working end of the fastening tool is engaged with the threaded part 31 of the corresponding fastener 3. Then, by rotating the fastening tool, the threaded part 31 is rotated, and the threaded part 31 is engaged with the thread of the second component 2. In the cooperative relationship, the drive fastening part 33 moves along the axial direction of the fastener 3 towards the transverse frame 50 until the fastening part 33 and the surface of the transverse frame 50 are tightly pressed together, so as to achieve stable locking between the motor box frame 40 and the transverse frame 50. When disassembly is required, the fastening tool in the operating hole 12 is rotated in the opposite direction to reverse the threaded part 31, which drives the fastening part 33 to disengage from the pressing state. Then, the sliding part 32 of the fastener 3 is slid from the second sliding groove section 112 back to the first sliding groove section 111 and taken out from the groove 113 to complete the separation of the two.

[0048] By adopting the above technical solution, the design of the operating hole 12 effectively solves the problem that when assembling the horizontal frame 50 and the motor box frame 40, the fastening tool is difficult to contact the threaded part 31 of the fastener 3 due to the obstruction of the wall of the horizontal frame 50 or the limitation of the structural space. This ensures that both locking and disassembly operations can be carried out conveniently without disassembling other parts of the horizontal frame 50. At the same time, the one-to-one correspondence between the operating hole 12 and the slide 11 avoids the alignment deviation when inserting the tool, improving the operation accuracy and efficiency. Combined with the structural design of double slide 11 and double fastener 3, the assembly process is further simplified on the basis of enhancing the connection strength between the horizontal frame 50 and the motor box frame 40. In addition, the setting of the operating hole 12 does not affect the overall structural strength of the horizontal frame 50, nor does it increase the processing cost too much. It can synergize with the advantages of the guide assembly of the slide 11, further reducing the assembly difficulty of the office desk frame drive components, meeting the dual needs of efficient assembly in mass production and end-user self-maintenance, and ensuring the structural stability and operational convenience of the office desk frame in long-term use.

[0049] Please refer to it again. Figure 6 In one embodiment, when the second component 2 is a horizontal frame 50, the second component 2 is provided with a hook fixing claw 401 for fixing the hook 4. The hook fixing claw 401 is arranged vertically upward. The hook 4 is provided with a fixing hole 41 that cooperates with the hook fixing claw 401. The hook 4 is fixedly connected to the hook fixing claw 401 by its own weight.

[0050] Specifically, in the structure of this quick-release structure, when the second component 2 is the horizontal frame 50 of the office desk frame, the second component 2, i.e., the horizontal frame 50, is provided with a hook fixing claw 401 for fixing the hook 4. The hook fixing claw 401 is set vertically upward and is integrally formed with the horizontal frame 50 or is stably connected by welding or other means. The hook fixing claw 401 is columnar or other structural forms adapted to the installation of the hook 4. At the same time, the hook 4 used in conjunction is provided with a fixing hole 41 that matches the shape and size of the hook fixing claw 401. The fixing hole 41 can be accurately fitted onto the outside of the hook fixing claw 401, and the hook 4 itself has a certain weight to ensure that gravity can assist in fixing. In addition, the horizontal frame 50 still maintains the quick-release structure feature of cooperating with the first component 1 (such as the vertical frame 30, the motor box frame 40). The hook 4 fixing structure and the quick-release structure are independently set on the horizontal frame 50 and do not interfere with each other.

[0051] Its working principle is as follows: After the quick-release assembly of the horizontal frame 50 and the first component 1 is completed, if the hook 4 needs to be installed, the operator aligns the fixing hole 41 of the hook 4 with the vertically upward hook fixing claw 401 on the horizontal frame 50, so that the hook fixing claw 401 passes through the fixing hole 41. At this time, the hook 4 hangs down naturally under its own weight, and the inner wall of the fixing hole 41 fits tightly with the outer wall of the hook fixing claw 401. The downward force generated by gravity restricts the hook 4 from moving upward along the axial direction of the hook fixing claw 401. At the same time, the upward setting direction of the hook fixing claw 401 prevents the hook 4 from easily detaching due to lateral external force, thereby achieving a stable fixed connection between the hook 4 and the horizontal frame 50. When it is necessary to disassemble the hook 4, simply pull the hook 4 upward to overcome its own weight, so that the fixing hole 41 is disassembled from the hook fixing claw 401 to complete the disassembly.

[0052] By adopting the above technical solution, the hook 4 can be fixed without the need for additional screws, nuts, or other fasteners 3. It can be installed and fixed solely by the weight of the hook 4 itself, greatly simplifying the hook 4 assembly and disassembly process, lowering the operating threshold for non-professional users, and avoiding problems such as lost parts and cumbersome installation that are easily encountered when using traditional fasteners 3. The vertical upward setting of the hook fixing claw 401 can not only prevent the hook 4 from accidentally falling off during use (such as when hanging documents or tools), improving safety, but also ensure that the hook 4 is balanced in force when hanging items, adapting to the daily use scenarios of the office desk frame. At the same time, the hook fixing claw 401 has a simple structure and is easy to process, which will not increase the production and manufacturing cost of the horizontal frame 50. It also complements the quick-release structure of the horizontal frame 50, adding the hook 4 fixing function to the horizontal frame 50 on the basis of convenient assembly characteristics, further improving the overall practicality and functionality of the office desk frame, and meeting the user's dual needs for office desk frame storage function and ease of assembly.

[0053] like Figure 8 As shown, in one embodiment, when the first component 1 is a horizontal frame 50, the horizontal frame 50 includes two first frames 501 and a second frame 502 connecting the two first frames 501, and the second frame 502 is connected to the first frame 501 by bolts 503.

[0054] Specifically, in the structure of this quick-release structure, when the first component 1 is the horizontal frame 50 of the lifting table frame, the horizontal frame 50 is composed of two first frames 501 and one second frame 502. The two first frames 501 are arranged relatively spaced apart, and the second frame 502 is located between the two first frames 501 and is used to connect the two. The connection between the second frame 502 and each first frame 501 is assembled by bolts 503. The two ends of the second frame 502 are respectively attached to the preset connection end face or connection side of the corresponding first frame 501. The mating parts of the first frame 501 and the second frame 502 are provided with connecting holes for the fitting bolts 503. After the bolts 503 pass through the connecting holes, they are locked by thread engagement, so that the two first frames 501 and the second frame 502 together form a complete horizontal frame 50 structure. At the same time, the horizontal frame 50 still maintains the sliding groove 11 and operating hole 12 structure that mates with the second component 2, i.e. the motor box frame 40, as described above. The sliding groove 11 and the operating hole 12 are respectively opened on the first frame 501 or the second frame 502 of the horizontal frame 50 to meet the quick disassembly and assembly requirements with the motor box frame 40.

[0055] Its working principle is as follows: When assembling the horizontal frame 50, the operator first places the two first frames 501 at a preset interval, then aligns the two ends of the second frame 502 with the connection parts of the two first frames 501 and aligns the connection holes of the two. Then, the bolt 503 is inserted into the aligned connection hole, and the bolt 503 is rotated by a fastening tool to form a locking fit between the bolt 503 and the thread or matching nut in the connection hole until the second frame 502 and the two first frames 501 are tightly fitted and there is no relative looseness. The assembly of the horizontal frame 50 is completed. The assembled horizontal frame 50 can be connected to the fastener 3 of the motor box frame 40 through the sliding groove 11 on it to achieve quick disassembly. If it is necessary to disassemble the horizontal frame 50, simply rotate the bolt 503 in the opposite direction with a tool to release the lock and separate the second frame 502 from the two first frames 501.

[0056] By adopting the above technical solutions, the modular design of the horizontal frame 50 allows each frame component to be transported individually, significantly reducing packaging volume and transportation costs during transport. It also avoids the problem of the overall horizontal frame 50 being easily damaged during transport due to its large size. The bolt 503 connection method ensures the connection strength between the second frame 502 and the first frame 501, meeting the support and load-bearing requirements of the horizontal frame 50 for the lifting table, while also providing convenient disassembly and assembly for later maintenance or replacement of individual frame components. Furthermore, the modular structure allows for adjustment of the length of the second frame 502 or the spacing between the two first frames 501 to accommodate different sizes of lifting tabletops, improving the versatility of the horizontal frame 50. Combined with the quick-release assembly structure of the motor box frame 40, this further enhances the overall assembly flexibility and practicality of the lifting table, meeting the standardized processing needs of mass production and the personalized installation needs of end users. Secondly, an office desk is provided, including an office desk frame, an office desk panel, and the aforementioned quick-release structure, wherein the office desk panel is disposed on the office desk frame, and the quick-release structure is applied to the office desk frame.

[0057] By adopting the above technical solution, the aforementioned quick-release structure is integrated into the desk frame and combined with the desk board to form a complete desk. This can significantly improve assembly efficiency to meet the needs of end users for self-installation and rapid layout in the office space. It can also ensure the structural stability of the tightly connected parts of the desk frame to meet daily load-bearing and durability requirements. Furthermore, it can optimize the transportation and storage experience after disassembling the desk frame parts to reduce costs and damage risks. It can also improve versatility and ease of maintenance to reduce production mold costs and waste of later maintenance resources. In addition, it can enhance the flexibility of use to adapt to the needs of office space adjustment and functional upgrade.
