Description

Technical Field

[0001] This utility model belongs to the field of desktop fixing technology, and specifically relates to a desktop fixing buckle. Background Technology

[0002] In daily life and office environments, modular desktops are becoming increasingly popular with users due to the emergence of online shopping. These desktops require users to assemble them themselves after purchase before use.

[0003] Existing modular tabletops typically require screws or other fasteners to assemble the tabletop and legs.

[0004] The shortcomings of this technical solution are as follows: First, when assembling with screws or fasteners, holes need to be drilled in the bottom of the desktop and then tightened. As the usage time increases, if the drilled points become loose, the stability of the desktop will decrease. At this time, it is necessary to find new drilling points to stabilize the desktop, which will damage the integrity of the desktop and the regularity of the desktop after re-fixation. In other words, the drilled assembly desktop is not conducive to subsequent maintenance. Second, the existing screw fixing method requires the use of screwdrivers and other tools during assembly and disassembly, making assembly and disassembly inconvenient.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a desktop fixing buckle, and the technical problem to be solved is as follows: the existing desktop splicing structure requires drilling holes at the bottom of the desktop during use, which damages the integrity of the desktop, and the disassembly and assembly are relatively inconvenient.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A desktop fixing buckle includes a tabletop, a fixed fastener fixedly connected to one side of the tabletop, and a movable fastener detachably connected to one side of the fixed fastener. The fixed fastener has slots on both sides, and the movable fastener has fasteners on both sides of its interior that fit the slots, with the slots engaging with the fasteners on adjacent sides. A limiting frame is provided at the top of the fixed fastener, and a slot is provided in the middle of the movable fastener that fits the limiting frame, with the limiting frame and the slot slidably connected. A first locking slot is provided in the middle of the fixed fastener, and a second locking slot is provided in the middle of the movable fastener; both locking slots are used to engage with the top edge of the table legs.

[0009] As a further embodiment of this utility model: the fixed fastener also includes a bottom frame that is fixedly connected to the tabletop, one side of the bottom frame is fixedly connected to the limiting frame, and four slots are symmetrically arranged on both sides of the bottom frame, the shape of the slots being adapted to the shape of the buckle.

[0010] As a further embodiment of this utility model: the buckle is provided with an inlet inclined surface on the vertical opening side near the movable fastener, and an outlet inclined surface is provided on the side away from the inlet inclined surface, wherein the inclination angle of the inlet inclined surface is smaller than the inclination angle of the outlet inclined surface.

[0011] As a further embodiment of this utility model: the bottom of the movable fastener is provided with a bottom insertion frame, the slot is provided on one side of the bottom insertion frame, and four buckles are symmetrically arranged on both sides of the inner side of the bottom insertion frame. The buckle slots correspond one-to-one with the buckles, and the inner side of the bottom insertion frame is provided with deformation clearance holes to accommodate the buckles.

[0012] As a further embodiment of this utility model: a tail buckle groove is provided at the bottom of the limiting frame on the side away from the opening, and a tail buckle is provided at the bottom of the slot on the side away from the opening, and the tail buckle is engaged with the tail buckle groove.

[0013] As a further embodiment of this utility model: the limiting frame and the slot are open on the same vertical plane, and anti-slip strips are evenly arranged on both sides of the outer side of the movable fastener.

[0014] The beneficial effects of this utility model are:

[0015] By setting fixed fasteners on the bottom surface of the tabletop, setting limiting frames on the bottom surface of the fixed fasteners, and setting multiple slots on both sides of the bottom connection frame connected to the tabletop, setting a first slot in the middle of the fixed fastener, and setting a movable fastener that is paired with the fixed fastener, and setting a buckle with a deformation clearance hole in the adapter slot inside the movable fastener, and setting a second slot, after the movable fastener and the fixed fastener are fastened together, the slot of the fixed fastener aligns with its corresponding buckle, and the top of the tabletop is snapped between the fixed fasteners. At the same time, the total socket surrounded by the first and second slots is inserted into the top edge of the table leg. This avoids the installation method of drilling holes in the bottom of the tabletop with tools when assembling the tabletop in the existing technology, thereby achieving nail-free locking of the table legs and improving the convenience of tabletop assembly.

[0016] Furthermore, the moving fastener has a deformation clearance hole adapted to the inside of the buckle. The angle of the guide slope on one side of the buckle is small, while the angle of the guide slope on the other side is large. When the fixed fastener and the moving fastener are connected, the deformation clearance hole can temporarily accommodate the buckle, avoiding damage to the buckle's elasticity caused by rigid deformation. The smaller angle of the installation cut-in facilitates the connection between the fixed fastener and the moving fastener. After connection, the larger guide slope provides stronger clamping ability, preventing loosening of the clamping state due to accidental contact. This reduces the effort required to assemble the tabletop and improves the stability of the tabletop after assembly. In addition, the deformation clearance hole allows the moving fastener to maintain the buckle's elasticity after multiple disassemblies and reassemblies. When the moving fastener is repaired or replaced, the table leg assembly position can remain unchanged, thus making the buckle easy to disassemble and reassemble while maintaining the stability of the tabletop's usage state before and after maintenance.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 7 As shown, a desktop fixing buckle includes a tabletop 1. A fixed fastener 2 is fixedly connected to one side of the tabletop 1, and a movable fastener 3 is detachably connected to one side of the fixed fastener 2. The fixed fastener 2 has slots 21 on both sides, and the movable fastener 3 has buckles 31 on both sides that fit the slots 21. The slots 21 engage with the buckles 31 on the adjacent side. A limiting frame 22 is provided at the top of the fixed fastener 2, and a slot 32 is provided in the middle of the movable fastener 3 that fits the limiting frame 22. The limiting frame 22 and the slot 32 are slidably connected. A first latch 23 is provided in the middle of the fixed fastener 2, and a second latch 33 is provided in the middle of the movable fastener 3. The first latch 23 and the second latch 33 are used to engage with the top edge of the table leg.

[0028] It should be noted that the tabletop 1 and the fixed fastener 2 are an integral structure. During the assembly of the tabletop and table legs, the assembly is completed by connecting the movable fastener 3 to the fixed fastener 2, which is fixed to the tabletop 1. Both the limiting frame 22 and the slot 32 are single-opening structures with three closed sides and one open side. Preferably, after the fixed fastener 2 and the movable fastener 3 are connected, the open side is flush with the vertical plane (see...). Figure 1 The purpose is to ensure that when the docking is accidentally touched, the docking state will not be shifted due to the protrusion on the docking side, thus improving docking stability.

[0029] like Figures 2 to 4 As shown, the fixed fastener 2 also includes a bottom frame 24 that is fixedly connected to the tabletop 1. The top of the bottom frame 24 is fixedly connected to the limiting frame 22. Four slots 21 are symmetrically arranged on both sides of the bottom frame 24. The concave shape of the slots 21 is adapted to the protrusion shape of the buckle 31.

[0030] The buckle 31 has an inlet ramp 311 on the side of the vertical opening near the movable fastener 3, and an outlet ramp 312 on the side away from the inlet ramp 311. The inclination angle of the inlet ramp 311 is smaller than the inclination angle of the outlet ramp 312.

[0031] The bottom of the movable fastener 3 is provided with a bottom insertion frame 34, and the slot 32 is provided on one side of the bottom insertion frame 34. Four buckles 31 are symmetrically arranged on both sides of the inner side of the bottom insertion frame 34. A deformation clearance hole 35 is adapted to be opened on one side of the buckle 31 on the inner side of the bottom insertion frame 34.

[0032] It should be noted that since the slot 21 and the buckle 31 have the same shape, when the angle of the guide slope 311 is small, the force on the buckle 31 gradually increases during the pushing process of the movable fastener 3, and the increase is slow. This results in a smoother docking process, avoiding the need for the fixed fastener 2 and the movable fastener 3 to dock with more effort. After the fastener is engaged, the angle of the guide slope 312 is larger, which is used to maintain the stability after the docking is completed, and to prevent easy disengagement when subjected to external force. This improves the convenience of the fastening process and the stability after the fastening is completed. In addition, the buckle 31 is made of elastic plastic or elastic steel sheet, etc. When the fixed fastener 2 and the movable fastener 3 are pushed, the buckle 31 initially contracts to the deformation relief hole 35 due to its own elasticity, until it docks and resets with the matching slot 21.

[0033] like Figures 3 to 5 As shown, a tail buckle groove 25 is provided at the bottom of the limiting frame 22 on the side away from its opening, and a tail buckle 36 is provided at the bottom of the slot 32 on the side away from its opening. The tail buckle 36 and the tail buckle groove 25 are engaged.

[0034] Anti-slip strips 37 are evenly distributed on both sides of the outer side of the movable fastener 3;

[0035] It should be noted that when the fixed fastener 2 and the movable fastener 3 are connected, the installer pushes the movable fastener 3 towards the fixed fastener 2 by holding the anti-slip strips 37 on both sides of the movable fastener 3. Then the limiting frame 22 and the slot 32 slide to connect, the bottom connecting frame 24 connects with the bottom insert frame 34, and the buckle 31 retracts to the deformation clearance hole 35 until it is reset in the corresponding slot 21. At this time, the tail buckle 36 and the tail buckle slot 25 connect to prevent disengagement. The opening sides of the fixed fastener 2 and the movable fastener 3 are on the same vertical plane, and the first buckle 23 and the second buckle 33 are combined into a total insertion port. The entire connection process does not require tools and does not require drilling holes in the bottom of the desktop. If the movable fastener 3 has poor fastening stability, it can be replaced without re-drilling holes in the bottom of the desktop. This provides the advantages of more convenient disassembly and assembly, and no need to reposition and fix it during subsequent maintenance. This improves the efficiency of desktop installation and maintains the support stability of the desktop before and after maintenance.

[0036] Specifically, such as Figure 6 and Figure 7As shown, four fixed fasteners 2 are fixedly connected to the bottom surface of the tabletop 1, and are symmetrical about both sides of the bottom surface of the tabletop 1. The opening direction of the latches 23 of two adjacent fixed fasteners 2 is opposite. The top of the table legs is an H-shaped square tube frame 4. The edge shape of the square tube frame 4 is the same as the shape of the main insertion port. Preferably, the side of the square tube frame 4 and the latch 33 are interference fit. That is, when locking the table legs, the square tube frame 4 is inserted between the four fixed fasteners 2, and then the movable fastener 3 is pushed to connect with the fixed fasteners 2 in sequence. After the connection is completed, the tabletop 1 and the table legs are integrated, and the table assembly is completed. Since the movable fastener 3 and the square tube frame 4 are interference fit, the connection of the latch 21 and the latch 31 and the connection of the tail latch 25 and the tail latch 36 improve the stability of the locking system. Moreover, the locking is a nail-free locking, which is convenient for disassembly and assembly and also convenient for subsequent maintenance and replacement.

[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
