A connection seat that can slide along the column and has a buckle groove is provided, and the layer plates are buckled in the corresponding buckle grooves through a buckle joint, the connection seat is used to support the layer plates to ensure that the layer plates maintain a horizontal posture, and also to pull the layer plates, so that the layer plates and the column are fitted together, the assembly accuracy is improved by eliminating the gap between the two, the layer plates are prevented from offsetting and jumping, and the user experience is improved.

[0005] Preferably, a buckle joint is provided at the end of the connecting rod, the buckle groove includes a wide mouth portion and a narrow mouth portion, the width of the buckle joint is between the width of the wide mouth portion and the width of the narrow mouth portion, the buckle joint is inserted into the buckle groove through the wide mouth portion and is clamped and positioned after sliding to the narrow mouth portion. The buckle joint is buckled in the buckle groove, the wide mouth portion can facilitate the insertion of the buckle joint into the buckle groove, and the narrow mouth portion can clamp and position the buckle joint to prevent the buckle joint from being separated from the buckle groove, which not only ensures that the layer board is supported by the buckle groove, but also ensures that the layer board is horizontally limited by the buckle joint.

[0006] Preferably, a guide channel for guiding the sliding of the buckle joint is provided in the buckle groove, and the depth of the section corresponding to the guide channel and the narrow mouth portion is greater than the depth of the section corresponding to the guide channel and the wide mouth portion. The buckle joint slides along the guide channel and drives the layer plate to approach and tighten the connection seat to eliminate the gap between the layer plate and the column. The buckle groove cavity forms the guide channel, and the narrow mouth portion and the deep mouth portion are set at different depths to make the guide channel inclined. The buckle joint can slide along the guide channel, which not only ensures that the buckle joint can slide from the wide mouth portion to the narrow mouth portion, and plays a role in preventing the buckle joint from detaching from the buckle groove, but also increases the setting depth of the guide channel to pull the buckle joint, ensuring that the layer plate can approach the connection seat and eliminate the gap between the layer plate and the column, thereby improving the positioning reliability of the layer plate.

[0007] Preferably, both side walls of the connection seat are provided with assembly holes, a columnar plug-in is provided in the assembly hole, the buckle groove is provided on the end wall of the plug-in, and an anti-skid rib is provided on the outer side wall of the plug-in. The plug-in is inserted and fixed in the assembly hole so that the buckle groove is exposed and provided for the connection rod to buckle. The plug-in and the connection seat are separate structures, which facilitates the use of different materials for processing, effectively reducing the processing difficulty of the plug-in. Anti-skid ribs are provided on the plug-in to effectively prevent the plug-in from detaching from the assembly hole, ensuring that the connection seat can pull the layer plate through the plug-in that cooperates with the connection rod, and play a role in positioning the layer plate.

[0008] Preferably, the plug-in is rotatably arranged in the assembly hole, the narrow mouth portion is arranged in the center of the end wall of the plug-in, and the wide mouth portion is eccentrically arranged on the end face of the plug-in, so that the assembly direction between the fastener and the buckle slot is adjustable. The plug-in is rotatably connected in the assembly hole, so that the relative position between the narrow mouth portion and the wide mouth portion can be changed, so that the direction in which the buckle joint is inserted into the buckle slot can be changed, which is convenient for the assembly and disassembly of the layer board. The narrow mouth portion is arranged in the center of the end wall of the plug-in, ensuring that the buckle joint is coaxially arranged with the plug-in when installed in place, effectively improving the anti-deformation performance around the narrow mouth portion, and preventing the layer board from being offset due to the deformation of the plug-in.

[0009] Preferably, the wide mouth portion is located above the narrow mouth portion, so that the buckle joint moves from top to bottom into the narrow mouth portion after passing through the wide mouth portion. The buckle joint passes through the guide channel from top to bottom and is clamped in the narrow mouth portion, which not only improves the supporting reliability, but also realizes horizontal limitation through the cooperation between the buckle joint and the narrow mouth portion.

[0010] Preferably, the buckle joint is telescopically arranged on the end of the connecting rod, and a spring is arranged inside the connecting rod to drive the buckle joint to extend and reset. The buckle joint is forced to switch to the avoidance position retracted into the connecting rod and forms a reset preload force by compressing the spring, so that the buckle joint can be reset under the reset preload force and slide along the guide channel to the narrow mouth. The connecting rod is completely hidden in the layer board, and the buckle joint avoids the buckle slot by shrinking inward, which not only ensures that the buckle joint can be inserted into the buckle slot by resetting when moving to the wide mouth, but also ensures that the layer board can be smoothly installed between adjacent connecting seats, so that the side wall of the layer board fits tightly with the side wall of the corresponding connecting seat, effectively eliminating the gap between the layer board and the connecting seat, and between the layer board and the column. Under the action of the spring's reset preload, the snap joint has a tendency to extend outward, and the inclined wall of the guide channel is used to convert the force, so that the snap joint can convert the axial force extending outward along the axis of the connecting rod into a radial force moving toward the narrow mouth along the guide channel. This not only guides the movement of the snap joint, but also limits the snap joint from escaping from the snap groove along the guide channel, thereby ensuring the reliability of the connection.

[0011] Preferably, a screw hole is provided on the side wall of the layer board, and a thread is provided on the outer side wall of the connecting rod, and the connecting rod is screwed into the screw hole, so that the layer board is pulled by the connecting rod and moves closer to the connecting seat. The connecting rod is screwed and hidden with the screw hole as a whole, which is convenient for buckling with the connecting seat by using the exposed buckle joint, and also improves the connection strength between the connecting rod and the layer board, and eliminates the gap by pulling the layer board closer to the connecting seat.

[0012] Preferably, a positioning hole communicating with the assembly hole is provided on the inner end wall of the connection seat facing the column, and a fastener screwed with the positioning hole is inserted into the assembly hole and clamps the plug-in component to prevent the plug-in component from being separated from the assembly hole. The fastener is screwed with the positioning hole and the end of the fastener is inserted into the assembly hole to contact the plug-in component, so that the plug-in component is reliably clamped in the assembly hole, preventing the plug-in component from being separated and deflected, and ensuring that the layer board can be installed on the connection seat through the connecting rod.

[0013] Preferably, the connection seat is provided with a fixing hole extending through the center line of the inner end wall, the column is provided with a slide groove extending along its length direction, a slider is provided in the slide groove, the connection seat is screwed and locked with the slider by a positioning bolt passing through the fixing hole, and the connection seat sliding along the slide groove drives the slider to approach and clamp on the column by the positioning bolt. The slider is connected to the fastener and realizes linkage with the connection seat, the connection seat slides and adjusts along the slide groove of the column under the guidance of the slider, and after being adjusted in place, the slider is tightened to ensure that the slider approaches the connection seat, and then the facing surfaces of the slider and the connection seat are used to clamp the periphery of the slide groove notch to achieve clamping and positioning, ensuring that the connection seat is fixed to the column. The slide groove is in the shape of a small cavity, which is convenient for the slider to slide in the slide groove and prevents the slider from detaching through the notch.

[0014] Preferably, the connection seat is in a cubic shape, and the width of the connection seat matches the thickness of the column. After being assembled in place, the column supports the layer plates on both sides through the connection seat, and the layer plates are attached to the side walls of the column and smoothly connected to the top surface of the connection seat. The connection seat is in a cubic shape, so that the adjacent side walls of the connection seat are perpendicular to each other, which ensures that the layer plates can be attached to the side walls of the connection seat, the inner end wall of the connection seat can be attached to the column, and the layer plates can be attached to the column and arranged vertically, so as to assemble and form a space that meets the use requirements.

[0015] The beneficial effects of the utility model are as follows: a connecting seat which can slide along the column and has a buckle groove is provided, and the layer board is buckled in the corresponding buckle groove through the buckle joint. The connecting seat not only supports the layer board to ensure that the layer board maintains a horizontal posture, but also has a pulling effect on the layer board, so that the layer board and the column are fitted together.

DETAILED DESCRIPTION

[0023] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and 2The assembly structure of a connecting seat for a layer shown in the figure is composed of a column 1 and layers 2 fixedly connected to both sides of the column 1 at the same height. The layer 2 is fixed to the column 1 through an assembly component. The assembly component includes a connecting seat 3 that can be lifted and fixed along the column 1 and a connecting rod 4 arranged on the corresponding side wall of the layer 2. The two side walls of the connecting seat 3 are provided with buckle grooves 5 for buckling the ends of the connecting rod 4. The buckle grooves 5 support the layer 2 through the connecting rod 4 and pull the layer 2 toward each other horizontally, so that the layer 2 and the column 1 are tightly fitted and positioned. A connecting seat 3 that can slide along the column 1 and has a buckle groove 5 is provided. The layer 2 is buckled into the corresponding buckle groove 5 through a buckle joint 6. The connecting seat 3 is used to support the layer 2 to ensure that the layer 2 maintains a horizontal posture, and also has a pulling effect on the layer 2, so that the layer 2 and the column 1 are fitted together. The assembly accuracy is improved by eliminating the gap between the two, and the layer 2 is prevented from offsetting and jumping, thereby improving the user experience.

[0025] In actual operation, the end of the connecting rod 4 is provided with a buckle joint 6, the buckle slot 5 includes a wide mouth portion 7 and a narrow mouth portion 8, the width of the buckle joint 6 is between the width of the wide mouth portion 7 and the width of the narrow mouth portion 8, the buckle joint 6 is inserted into the buckle slot 5 through the wide mouth portion 7 and is clamped and positioned after sliding to the narrow mouth portion 8. The width of the area corresponding to the notch of the buckle slot 5 and the wide mouth portion 7 is greater than the area corresponding to the narrow mouth portion 8, so that the buckle joint 6 can be inserted into the buckle slot 5 through the wide mouth portion 7 and is clamped and positioned when moving to the narrow mouth portion 8.

[0026] During installation, first, the connecting rod 4 is screwed into the corresponding screw hole 14 on the side wall of the layer board 2, so that the connecting rod 4 is hidden in the layer board 2 and the buckle joint 6 is exposed on the side wall of the layer board 2; then, the connecting seat 3 is screwed to the slider 17 set in the slide groove 16 through the fastener, and the connecting seat 3 moves and adjusts along the slide groove 16 under the guidance of the slider 17; then, the connecting seat 3 is moved to the preset position and the fastener is locked so that the slider 17 and the connecting seat 3 clamp the edge of the slot 16, so that the connecting seat 3 is fixed to the column 1; finally, the layer board 2 is buckled on the buckle groove 5 of the connecting seat 3 through the exposed buckle joint 6, and the buckle joint 6 is inserted into the buckle groove 5 through the wide mouth part 7 and slides along the guide channel to the narrow mouth part 8 and is then clamped and locked.

[0027] After installation, the layer board 2 is fixed to the column 1 through the assembly assembly, and the position of the layer board 2 can be adjusted by moving the connecting seat 3, which effectively improves the convenience of use. The connecting seat 3 is arranged on the end surface of the column 1, and the layer board 2 is fixed to the side wall of the connecting seat 3 and contacts the side wall of the column 1, effectively eliminating the gap between the layer board 2 and the column 1.

[0028] In actual operation, the buckle groove 5 is provided with a guide channel for guiding the buckle joint 6 to slide. The depth of the section corresponding to the narrow mouth 8 of the guide channel is greater than the depth of the section corresponding to the wide mouth 7 of the guide channel. The buckle joint 6 slides along the guide channel and drives the layer board 2 to move closer to the connecting seat 3 and tighten, so as to eliminate the gap between the layer board 2 and the column 1. The guide channel is formed by the groove cavity of the buckle groove 5. The depth of the section corresponding to the wide mouth 7 of the guide channel is less than the depth of the section corresponding to the narrow mouth 8 (such as Figure 6 As shown in the figure, when the buckle joint 6 moves along the guide channel toward the narrow mouth 8, the guide channel can convert the radial force generated when the buckle joint 6 moves into an axial force to pull the connecting rod 4, thereby making the side wall of the layer plate 2 move closer to the connecting seat 3, effectively reducing the distance between the side wall of the layer plate 2 and the side wall of the column 1.

[0029] In actual operation, the buckle joint 6 is telescopically arranged on the end of the connecting rod 4, and a spring 13 is arranged inside the connecting rod 4 to drive the buckle joint 6 to extend and reset. The buckle joint 6 is forced to switch to the avoidance position retracted into the connecting rod 4 and a reset preload force is formed by compressing the spring 13, so that the buckle joint 6 can be reset under the drive of the reset preload force and slide along the guide channel into the narrow mouth portion 8. The buckle joint 6 is telescopically arranged at the end of the connecting rod 4, and the spring 13 drives the buckle joint 6 to switch from the retracted position retracted into the connecting rod 4 to the extended position exposed to the connecting rod 4. During installation, since both sides of the layer board 2 need to be fixedly connected to the corresponding connecting seat 3 through the connecting rod 4, and the distance between the corresponding surfaces of the connecting seat 3 is consistent with the width of the layer board 2, the fastener crosses the periphery of the fastening groove 5 by switching to the retraction position, ensuring that the fastening joint 6 can be inserted into the corresponding fastening groove 5 by resetting to the outward extension position after the layer board 2 is inserted into the corresponding connecting seat 3, thereby making the two sides of the layer board 2 clamped and fixed by the corresponding connecting seat 3, ensuring that the layer board 2 maintains a horizontal posture and can effectively support the load. Since the snap joint 6 can be reset to the outward extending position under the drive of the spring 13, the snap joint 6 can convert the reset pre-tightening force from the spring 13 into an axial force applied outward along the axial direction of the connecting rod 4. The axial force is converted into a radial force transmitted along the radial direction of the connecting rod 4 through the inclined wall of the guide channel, so that the snap joint 6 can move toward the narrow mouth 8 along the guide channel under the drive of the radial force, and the snap joint 6 can use the spring 13 to achieve self-locking, effectively preventing the snap joint 6 from escaping from the snap groove 5 through the guide channel due to being retracted into the connecting rod 4.

[0030] In actual operation, the wide mouth portion 7 is located above the narrow mouth portion 8 (eg Figure 5As shown in the figure), the buckle joint 6 moves from top to bottom into the narrow mouth part 8 after passing through the wide mouth part 7, so that the layer plate 2 can move from top to bottom and drive the buckle part to be inserted into the wide mouth part 7 and slide downward into the narrow mouth part 8. After being installed in place, the buckle joint 6 can use the periphery of the narrow mouth part 8 to realize vertical and radial force to prevent the buckle joint 6 from deviating downward and horizontally. It can also use the periphery of the narrow mouth part 8 to realize axial limitation along the connecting rod 4 to prevent the buckle joint 6 from deviating axially along the connecting rod 4. It can also use the inclined side wall of the guide channel to realize vertical limitation to prevent the buckle joint 6 from deviating upward, thereby ensuring that the buckle joint 6 is stably clamped in the buckle groove 5.

[0031] In actual operation, both side walls of the connection seat are provided with assembly holes 9 (such as Figure 3 As shown), a columnar plug-in 10 is provided in the assembly hole 9, the buckle groove 5 is arranged on the end wall of the plug-in 10, and an anti-skid rib 11 is provided on the outer wall of the plug-in 10. The plug-in 10 is inserted and fixed in the assembly hole 9 so that the buckle groove 5 is exposed and provided for the connecting rod 4 to buckle. The plug-in 10 and the connecting seat 3 are split structures, so that the plug-in 10 and the connecting seat 3 can be formed by processing different materials. Specifically, the plug-in 10 is processed by injection molding, which can not only reduce the sliding resistance between the guide channel and the buckle joint 6, but also facilitate the processing to form the buckle groove 5. The connecting seat 3 is a metal part, which can not only ensure the structural strength, provide effective support for the layer plate 2, but also improve the aesthetics. The plug-in 10 is cylindrical, which is not only convenient for processing, but also convenient for insertion into the assembly hole 9. The outer wall of the plug-in 10 is provided with an anti-skid rib 11, which improves the anti-slip reliability by increasing the friction between the assembly hole 9. During installation, the plug-in component 10 is inserted into the assembly hole 9 , and the end surface of the plug-in component 10 is flush with the side wall of the connecting seat 3 , so that the buckle groove 5 is exposed on the side wall of the connecting seat 3 .

[0032] In actual operation, the plug-in component 10 is rotatably arranged in the assembly hole 9, the narrow mouth portion 8 is arranged at the center of the end wall of the plug-in component 10, and the wide mouth portion 7 is eccentrically arranged on the end surface of the plug-in component 10, so that the assembly direction between the fastener and the buckle groove 5 can be adjusted. The plug-in component 10 is rotatably arranged in the assembly hole 9, so that the relative position between the narrow mouth portion 8 and the wide mouth portion 7 is adjustable, thereby facilitating the layer board 2 to adjust the installation direction according to actual conditions. In a preferred solution, the narrow mouth portion 8 is not arranged higher than the wide mouth portion 7, ensuring that the buckle joint 6 will not be separated from the buckle groove 5 through the guide channel under the guidance of the gravity of the layer board 2.

[0033] In actual operation, the inner end wall of the connection seat 3 facing the column 1 is provided with a positioning hole 12 connected to the assembly hole 9, and the fastener screwed with the positioning hole 12 is inserted into the assembly hole 9 and clamps the plug-in 10 to prevent the plug-in 10 from being separated from the assembly hole 9. The fastener is screwed with the positioning hole 12 and clamps the plug-in 10 through the end, which not only limits the rotation of the plug-in 10, ensuring that the relative position between the wide mouth portion 7 and the narrow mouth portion 8 will not change due to the deflection of the plug-in 10, thereby ensuring that the layer 2 can be accurately assembled, but also ensures that the plug-in 10 is always located in the assembly hole 9, preventing the plug-in 10 from being exposed in the assembly hole 9 and hindering the insertion of the layer 2 into the connection seat 3. Each assembly hole 9 is provided with two separate positioning holes 12, and the positioning effect of the plug-in 10 is improved by increasing the number of positioning holes 12.

[0034] In actual operation, the side wall of the layer board 2 is provided with a screw hole 14, and the outer side wall of the connecting rod 4 is provided with a thread. The connecting rod 4 is screwed into the screw hole 14, so that the layer board 2 is pulled by the connecting rod 4 and moves closer to the connecting seat 3. The two side ends of the layer board 2 are provided with screw holes 14, so that the layer board 2 can be fixed to the corresponding connecting seat 3 through at least four connecting rods 4, ensuring that the layer board 2 can stably bear weight and maintain a horizontal posture. The outer side wall of the connecting rod 4 is provided with a thread, so that the connecting rod 4 can be screwed and locked with the screw hole 14 to prevent the connecting rod 4 from being separated from the screw hole 14.

[0035] In actual operation, the connection seat 3 is in a cubic shape, and the width of the connection seat 3 matches the thickness of the column 1. After being assembled in place, the column 1 supports the layer plates 2 arranged on both sides through the connection seat 3, and the layer plates 2 are attached to the side walls of the column 1 and smoothly connected with the top surface of the connection seat 3. The width of the connection seat 3 corresponds to the thickness of the column 1, and the side walls of the connection seat 3 are arranged parallel to each other and perpendicular to the inner end wall of the connection seat 3, so that the layer plates 2 can be tightly attached to the side walls of the column 1 under the pulling action of the connection seat 3, thereby ensuring that the layer plates 2 are accurately installed between adjacent columns 1.

[0036] In actual operation, the connection seat 3 is provided with a fixing hole 15 (such as Figure 4As shown in the figure, the column 1 is provided with a slide groove 16 arranged along its length direction, and a slider 17 is arranged in the slide groove 16. The connection seat 3 is screwed and locked with the slider 17 through a positioning bolt 18 passing through the fixing hole 15. The connection seat 3 sliding along the slide groove 16 drives the slider 17 to approach and clamp on the column 1 through the positioning bolt 18. The slider 17 is installed through the opening of the slide groove 16 port, so that the slider 17 can slide along the slide groove 16 and effectively prevent the slider 17 from being separated from the slide groove 16. The slider 17 not only guides the connection seat 3 to move along the length direction of the column 1, but also cooperates with the connection seat 3 to clamp the edge of the notch of the slide groove 16, so that the connection seat 3 can be clamped and positioned at a preset position, thereby providing effective support for the layer board 2.
