Further, the specific structure of the connection assembly of embodiment 1 of the present utility model is described in detail below. As shown in fig. 3 to 16, the connection assembly comprises a first connection member 1 and a second connection member 2, wherein a connection groove 11 is formed on the left side wall or the right side wall of the first connection member 1, an inclined unlocking surface 12 is formed between the upper side inner wall of the connection groove 11 and the bottom of the connection groove 11, a first adjusting surface 13 which gradually inclines towards the rear lower direction is formed on the front side inner wall of the connection groove 11, a second adjusting surface 14 which gradually inclines towards the front lower direction is formed on the rear side inner wall of the connection groove 11, the first adjusting surface 13 and the second adjusting surface 14 are oppositely arranged at intervals, and the first connection member 1 is used for being slidably installed in an installation groove 41 of the cabinet body 4; the second connecting piece 2 comprises a connecting part 21, an outer cylinder part 22 and an elastic part 23 arranged in the outer cylinder part 22, one end of the elastic part 23 is connected with the outer cylinder part 22, the other end of the elastic part 23 is connected with the connecting part 21, the connecting part 21 stretches back and forth relative to the outer cylinder part 22 through the elastic part 23, the outer cylinder part 22 is used for being fixedly arranged on one side of the laminate 5, and one end, away from the elastic part 23, of the connecting part 21 is inserted into the connecting groove 11; wherein, the first adjusting surface 13 is used for driving the first connecting piece 1 to slide forwards by the connecting part 21 when the connecting part 21 moves downwards and abuts against the first adjusting surface 13; the second adjusting surface 14 is used for driving the first connecting piece 1 to slide backwards when the connecting portion 21 moves downwards and abuts against the second adjusting surface 14.
It will be appreciated that the connecting groove 11 may be located on the left side wall of the first connector 1, or the connecting groove 11 may be located on the right side wall of the first connector 1, the position of the connecting groove 11 in the first connector 1 being adapted to the particular side of the laminate 5 to which the cabinet 4 is connected. The connecting groove 11 is located on the right side wall of the first connecting member 1, for example, when the left side wall of the deck 5 is connected to the left side inner wall of the cabinet 4; for example, the connecting groove 11 is located on the left side wall of the first connecting member 1 when the right side wall of the deck 5 is connected to the right side inner wall of the cabinet 4. In some embodiments, the two first connectors 1 are respectively mounted on the left and right inner side walls of the cabinet 4 and are axisymmetrically arranged about the connecting groove 11, and the left and right sides of the laminate 5 are respectively connected with the first connectors 1 on the left and right sides of the cabinet 4 through the second connectors 2, so that the laminate 5 is mounted in the cabinet 4.
In order to mount the first connector 1 on the left inner wall or the right inner wall of the cabinet 4, as shown in fig. 19, a mounting groove 41 extending along the front-rear direction is machined on the left inner wall or the right inner wall of the cabinet 4, the shape of the mounting groove 41 is matched with that of the first connector 1, the mounting groove 41 is specifically machined through a drilling process, and the distance between the front side and the rear side of the mounting groove 41 is larger than that between the front side and the rear side of the first connector 1, so that after the first connector 1 is embedded in the mounting groove 41, the first connector 1 can slide in the front-rear direction in the mounting groove 41, the position of the first connector 1 on the cabinet 4 is adjusted through the interaction of the second connector 2 on the first connector 1, so that the second connector 2 and the first connector 1 are matched, and assembly is smooth, thus the problem that the assembly is difficult due to assembly errors caused by the position of the first connector 1 is avoided, or the cabinet 4 or the laminate 5 needs to be replaced because of the errors of the holes is avoided.
In order to mount the outer cylinder 22 of the second connector 2 on the left side wall or the right side wall of the laminate 5, the left side wall and/or the right side wall of the laminate 5 is provided with mounting holes 51 by drilling, the shape and size of the mounting holes 51 are matched with those of the outer cylinder 22, the outer cylinder 22 of the second connector 2 is inserted and fastened in the mounting holes 51 under the action of external force, after the assembly is finished, the second connector 2 is difficult to pull out from the mounting holes 51 (a large pulling force is required to pull out the second connector 2 from the mounting holes 51), so that the second connector 2 is firmly connected on the laminate 5, and the laminate 5 is firmly mounted in the cabinet 4 through the cooperation connection between the second connector 2 and the first connector 1.
As shown in fig. 5 to 11, the first adjustment surface 13 may be an inclined plane, an arc concave surface, an arc convex surface, or a wave surface, as long as the first adjustment surface 13 is gradually inclined from front to back and downward. Similarly, the second adjusting surface 14 may be an inclined plane, an arc concave surface, an arc convex surface, or a wave surface, as long as the second adjusting surface 14 is gradually inclined from back to front and downward.
Further, as shown in fig. 6 and 12, in order to smoothly insert the connection portion 21 into the connection groove 11, a distance L between the upper side of the first adjustment surface 13 and the upper side of the second adjustment surface 14 is greater than a width W of the connection portion 21, for example, L-W is greater than or equal to 0.5mm, so that when the laminate 5 moves downward in the cabinet 4, the connection portion 21 can be easily inserted into a gap between the upper side of the first adjustment surface 13 and the upper side of the second adjustment surface 14, so that the connection portion 21 is smoothly inserted into the upper side of the connection groove 11 and further moves downward. When there is an error in the mounting position of the first connector 1 in the mounting groove 41 (or when there is a positional error in the second connector 2 on the laminate 5), the downward moving connector 21 will abut against the first adjusting surface 13 or the second adjusting surface 14, when the connector 21 moves downward in the connecting groove 11 and abuts against the first adjusting surface 13, the connector 21 will drive the first connector 1 to slide forward in the mounting groove 41, or when the connector 21 moves downward in the connecting groove 11 and abuts against the second adjusting surface 14, the connector 21 will drive the second connector 2 to slide backward in the mounting groove 41, so that the first connector 1 is adjusted to a proper position, so that the connector 21 moves smoothly to the lower side of the connecting groove 11, and the assembly process of the laminate 5 in the cabinet 4 is completed. In addition, when there is no error in the mounting position of the first connector 1 in the mounting groove 41 (or when there is no position error in the second connector 2 on the laminate 5), the connecting portion 21 moves downward in the connecting groove 11 and does not contact the first adjusting surface 13 or the second adjusting surface 14, and at this time, the connecting portion 21 can move directly to the lower side of the connecting groove 11, thereby completing the assembly process of the laminate 5 in the cabinet 4.
So adjust the suitable position of first connecting piece 1 on cabinet body 4 through connecting portion 21 and first adjusting surface 13 or second adjusting surface 14 mutually supporting, effectively guaranteed that plywood 5 also can install smoothly with cabinet body 4 when first connecting piece 1 appears the position error at mounting groove 41, avoid dismantling the trouble of trompil again on cabinet body 4 or plywood 5 behind the coupling assembling, it is convenient and efficient to install. The connection assembly of the embodiment 1 of the utility model can improve the fault tolerance of the opening on the cabinet body 4 or the laminate 5, and ensure that the laminate 5 is smoothly mounted on the inner side wall of the cabinet body 4.
In some embodiments, as shown in fig. 5 to 9, the first protruding portion 15 is formed on the upper side wall and/or the lower side wall of the first connector 1 of embodiment 1 of the present utility model. Specifically, the upper side wall of the first connector 1 is formed with a first protruding portion 15, or the lower side wall of the first connector 1 is formed with a first protruding portion 15, or both the upper and lower side walls of the first connector 1 are formed with first protruding portions 15. The first protruding portion 15 may be integrally formed on the first connecting piece 1, for example, the first protruding portion 15 and the first connecting piece 1 may be formed into an integral member through an injection molding process, so that the overall structural strength is relatively high, and the connection is stable and reliable. In embodiment 1, the specific structure or shape of the first protruding portion 15 is not limited, that is, the first protruding portion 15 includes an inverted tooth structure or a bump structure or a protruding strip structure, and the number of inverted tooth structures or bump structures or protruding strip structures may be one or more. The frictional force of the first coupling member 1 moving in the right and left direction within the mounting groove 41 can be increased by the first protrusions 15 formed on the upper and/or lower side walls of the first coupling member 1 in this way, thereby restricting the lateral separation of the laminate 5 from the cabinet 4.
Further, in order to ensure that the first connector 1 slides in the front-rear direction in the mounting groove 41, the first protrusion 15 extends in the front-rear direction, so that the fastening force generated by the first protrusion 15 on the first connector 1 is in the left-right direction, and the friction force of the first connector 1 in the front-rear direction in the mounting groove 41 is small, thereby ensuring that the first connector 1 slides smoothly in the front-rear direction.
Specifically, for example, as shown in fig. 5 to 9, the upper and lower side walls of the first connector 1 are respectively formed with first bosses 15, and the first bosses 15 include a plurality of inverted tooth structures, which are sequentially arranged at intervals in the left-right direction. Wherein, the interval of the upper side wall or the lower side wall of the inverted tooth structure relative to the first connecting piece 1 sets up and is the slope form to when making first connecting piece 1 install to mounting groove 41, the inverted tooth structure takes place elastic deformation and produces to support tight power to the upside inner wall and/or the downside inner wall of mounting groove 41, has increased the frictional force that first connecting piece 1 removed along the left and right directions in mounting groove 41, thereby increase the tensile bearing capacity along horizontal between plywood 5 and the cabinet body 4, improve the connection fastness between plywood 5 and the cabinet body 4.
When the first connector 1 is inserted into the mounting groove 41 of the cabinet 4, the first protrusion 15 and the inner wall of the mounting groove 41 abut against each other, so that the first connector 1 is restricted to be difficult to be pulled out in the mounting groove 41.
In other embodiments, after the first connector 1 of the present embodiment 1 is inserted into the mounting groove 41, a gap exists between the first protrusion 15 and the inner side wall of the mounting groove 41, so that when the mounting directions of the first connector 1 in the mounting groove 41 are opposite (for example, the up-down directions are opposite), the first connector 1 can be easily removed and reinstalled. When the first connector 1 of this embodiment is located in the installation groove 41, the first connector 1 is easily pulled out from the installation groove 41, resulting in no lateral tensile capacity between the laminate 5 and the cabinet 4, and for this purpose, as shown in fig. 42 to 46, the connector assembly of this embodiment further includes an insert 6, an expansion hole 110 being formed on the left side wall or the right side wall of the first connector 1, and the insert 6 being adapted to be inserted into the expansion hole 110 to expand the upper side wall and/or the lower side wall of the first connector 1 outwardly. It will be appreciated that the number of expansion holes 110 may be one or more, and that the number of inserts 6 is the same as the number of expansion holes 110. For example, as shown in fig. 42, 44, 45, when the number of expansion holes 110 is one, the expansion holes 110 are located on the front side or the rear side of the connection groove 11, and the number of the inserts 6 is one; as shown in fig. 43, when there are two expansion holes 110, the two expansion holes 110 are located on the front and rear sides of the connection groove 11, and the number of the inserts 6 is two, and the two inserts 6 are inserted into the two expansion holes 110 in a one-to-one correspondence. The first connecting member 1 has a certain elasticity, specifically, for example, a plastic member, and when the insert 6 is inserted into the expansion hole 110 or the insert 6 rotates in the expansion hole 110 by a certain angle, the expansion hole 110 is elastically deformed, so that the upper sidewall and/or the lower sidewall of the first connecting member 1 is outwardly expanded.
Specifically, as shown in fig. 42 and 43, for example, the hole diameter of the expansion hole 110 is gradually reduced, the inner side wall of the expansion hole 110 may have an internal thread structure, and when the insert 6 is inserted into the expansion hole 110 by screwing (e.g., driving the insert 6 clockwise), the upper side wall and/or the lower side wall of the first connector 1 is expanded outwards, so that the first protruding portion 15 abuts against the inner side wall of the connecting groove 11, and at this time, the friction force of the first connector 1 moving in the left-right direction in the mounting groove 41 is increased, so that the tensile load-bearing capacity between the laminate 5 and the cabinet 4 in the transverse direction is increased. But at this time the first connector 1 can slide in the front-rear direction in the mounting groove 41. When the first connector 1 needs to be removed from the mounting groove 41, the back drive insert 6 is rotated to rotate the insert 6 out of the expansion hole 110.
As shown in fig. 44 and 45, the expansion hole 110 has an elliptical or oval shape, and the insert 6 has an elliptical or oval shape. When the first connector 1 needs to be mounted to the mounting groove 41, the first connector 1 is first placed in the mounting groove 41 in a clearance fit manner, then the insert 6 is also inserted into the expansion hole 110 in a clearance fit manner, and the insert 6 is driven to rotate by a certain angle (for example, 90 °/75 °/60 °/etc.), so that the upper side wall and/or the lower side wall of the first connector 1 expand outwards, and the first protruding portion 15 abuts against the inner side wall of the connecting groove 11, and at this time, the friction force of the first connector 1 moving in the left-right direction in the mounting groove 41 is increased, so that the tensile bearing capacity between the laminate 5 and the cabinet 4 in the transverse direction is increased. But at this time the first connector 1 can slide in the front-rear direction in the mounting groove 41. When the first coupling member 1 is to be removed from the mounting groove 41, the back drive insert 6 is rotated by a corresponding angle.
Or the inner side wall of the expansion hole 110 is smooth, the aperture is gradually reduced, the insert 6 is a pin or a cylinder, and the insert 6 is directly inserted into the expansion hole 110 to expand the upper side wall and/or the lower side wall of the first connecting piece 1 outwards, so that the first protruding portion 15 abuts against the inner side wall of the connecting groove 11, at this time, the friction force of the first connecting piece 1 moving in the left-right direction in the mounting groove 41 is increased, and the tensile bearing capacity between the laminate 5 and the cabinet 4 in the transverse direction is increased. When the first connector 1 needs to be removed, the insert 6 is simply pulled out of the expansion hole 110 by a tool.
In some embodiments, as shown in fig. 11, 17-18, the first connector 1 is formed with at least one first catch 16, e.g. the first catch 16 may be protruding from the side of the first connector 1 facing away from the notch of the connecting groove 11. Wherein, the structure of the first buckle 16 is a conventional structure in the technical field, for example, is a triangle, when the mounting groove 41 of the cabinet body 4 is a secondary groove (the secondary groove can be formed by a special drill bit through continuous milling twice), a protruding structure is formed on the side wall of the mounting groove 41, and after the first connector 1 is inserted into the mounting groove 41 and the protruding structure of the first buckle 16 and the mounting groove 41 are mutually matched and clamped, the first connector 1 is restricted to be pulled out from the mounting groove 41 along the left-right direction, thereby improving the connection firmness between the laminate 5 and the cabinet body 4. In addition, when the first buckle 16 is engaged with the protruding structure of the mounting groove 41, the first buckle 16 can synchronously slide along the front-rear direction in the mounting groove 41 along with the first connector 1 without affecting the sliding of the first connector 1 along the front-rear direction in the mounting groove 41.
In some embodiments, as shown in fig. 3 to 4 and fig. 12 to 16, in order to improve the tensile force bearing capacity of the laminate 5 and the cabinet 4 in the left-right direction through the first connector 1 and the second connector 2, one end of the connecting portion 21, which is away from the elastic portion 23, is formed with a connecting boss 211, and the connecting boss 211 is inserted into the connecting groove 11; a fastening flange 17 is formed on the inner wall of the lower side of the connection groove 11, and the fastening flange 17 cooperates with the connection boss 211 to limit the extraction or removal of the connection boss 211 from the connection groove 11. The fastening flange 17 may be in a continuous annular shape or in a convex shape arranged at intervals, when the laminate 5 is mounted on the cabinet body 4, the connecting portion 21 is located at the lower side of the connecting groove 11, meanwhile, the connecting boss 211 and the fastening flange 17 are mutually matched and clamped, and the connecting boss 211 is limited to be pulled out of the connecting groove 11 through the fastening flange 17, so that the first connecting piece 1 and the second connecting piece 2 are firmly connected, and the tensile bearing capacity of the laminate 5 and the cabinet body 4 in the left-right direction is improved through the first connecting piece 1 and the second connecting piece 2. At this time, a part of the first adjustment surface 13 and a part of the second adjustment surface 14 are located on the fastening flange 17, respectively.
Further, in some embodiments, as shown in fig. 5-9, the fastening flange 17 is formed with one or more clamping bumps 171, for example, the number of the clamping bumps 171 is two, and the two clamping bumps 171 are relatively spaced on the fastening flange 17, where the gap between the two clamping bumps 171 forms a bayonet, and the width dimension of the bayonet is smaller than the diameter dimension of the neck of the connecting portion 21, so that during the process of moving the connecting portion 21 to the lower side of the connecting slot 11, the neck of the connecting portion 21 will abut against the bayonet to elastically deform to increase, and after the neck of the connecting portion 21 passes through the clamping bumps 171, the bayonet returns to the original shape, so that the neck of the connecting portion 21 in the static state is difficult to pass through the bayonet without being influenced by external force, thereby improving the stability of the laminate 5 in the up-down direction in the cabinet 4.
In other embodiments, as shown in fig. 10, the upper and lower side walls of the first connecting member 1 are respectively smooth and planar, the fastening flange 17 is not provided on the inner side wall or the notch of the connecting groove 11, the portion of the connecting portion 21 inserted into the connecting groove 11 is polished rod-shaped, and at this time, the tensile force bearing capability between the first connecting member 1 and the second connecting member 2 in the left-right direction is poor, and the laminate 5 and the cabinet 4 are easily separated from each other in the left-right direction due to the transverse tensile force.
In some embodiments, as shown in fig. 12 to 15, the outer cylinder 22 is cylindrical or truncated cone-shaped, and an external thread 221 is formed on the outer circumferential side wall of the outer cylinder 22; the outer tube 22 has a mounting channel 222 for accommodating the elastic portion 23 and the connecting portion 21, two ends of the mounting channel 222 respectively penetrate through two opposite ends of the outer tube 22, a plug 24 is provided at a first end opening of the mounting channel 222 by a pressing process or a screw connection, the elastic portion 23 (the elastic portion 23 is specifically an elastic body such as a spring, a compression spring or a colloid) and the connecting portion 21 are inserted into the mounting channel 222 through a first end opening of the mounting channel 222, and a second end opening of the mounting channel 222 is in a necking shape to limit the separation of the connecting portion 21 from the outer tube 22, so that the connecting portion 21 reciprocates relative to the outer tube 22 through the elastic portion 23. The cross-sectional shape of the mounting channel 222 is the same as the cross-sectional shape of the inner ring of the sleeve, and the cross-sectional shape of the outer contour of the connection boss 211 is adapted to the cross-sectional shape of the sleeve. It will be appreciated that the mounting channel 222 is non-circular in shape to ensure that the coupling portion 21 can only slide axially within the mounting channel 222, limiting circumferential rotation of the coupling portion 21 relative to the outer barrel 22 along the mounting channel 222. The cross-sectional shape of the connection boss 211 is also non-circular, for example, triangular, square, hexagonal, octagonal, oval, waist-round, petal-shaped, etc., so that the socket wrench can drive the connection boss 211 to rotate, thereby driving the outer barrel 22 to rotate. Wherein, the cross section area of the mounting hole 51 is equal to or slightly smaller than the cross section area of the outer barrel 22, so that the outer barrel 22 can be self-tapped into the mounting hole 51 in the rotating process of the outer barrel 22, meanwhile, an inner thread structure which is in matched threaded connection with the outer barrel 22 is formed on the inner side wall of the mounting hole 51, so that the outer barrel 22 is fastened on the side wall of the laminate 5 in a threaded connection manner, and the second connecting piece 2 is limited to slide from the mounting hole 51, so that the second connecting piece 2 is fastened on the laminate 5. When the outer cylindrical portion 22 is made of plastic, the outer cylindrical portion 22 can be fitted into the fitting hole 51 by tapping and pressing. When the outer tube 22 is to be removed from the mounting hole 51, the outer tube 22 is simply rotated in the reverse direction.

The fastening protrusions 223 may be of an inverted tooth structure or a bump structure, and the cross-sectional area of the mounting hole 51 is equal to or slightly smaller than the cross-sectional area of the outer cylinder 22, so that the fastening protrusions 223 on the surface of the outer cylinder 22 are inserted into the mounting hole 51 in an interference fit manner, so that the second connector 2 is fastened to the laminate 5.
In some embodiments, since the first connector 1 can slide in the front-rear direction within the mounting groove 41, that is, the mounting groove 41 is configured in a non-circular shape, the mounting groove 41 is generally formed into a racetrack groove or a kidney-shaped groove since the mounting groove 41 is formed by a drilling process. Suitably, the first connecting piece 1 may be configured to have a racetrack shape or a oval shape when viewed in the left-right direction, and the upper and lower sidewalls of the first connecting piece 1 are respectively planar, so that the upper and lower outer sidewalls of the first connecting piece 1 are parallel to the upper and lower inner sidewalls of the mounting groove 41, thereby ensuring that the first connecting piece 1 slides in the mounting groove 41 in the front-rear direction.
In some embodiments, the connection assembly of embodiment 1 of the present utility model further includes a fastener (not shown), such as a screw or a bolt, where the left side wall or the right side wall of the first connection member 1 is formed with a through hole 18, and the through hole 18 may be a countersunk hole, and the fastener is disposed in the through hole 18. After the first connecting piece 1 is accurately installed in the installation groove 41 of the cabinet body 4, in order to further improve the connection firmness of the first connecting piece 1 on the cabinet body 4, a fastener is adopted to penetrate through the through hole 18 and then is connected on the cabinet body 4, so that the first connecting piece 1 is firmly locked on the cabinet body 4, and the first connecting piece 1 is limited to be pulled out from the connection groove 11.
Further, as shown in fig. 8, the perforations 18 are circular holes or oval holes or racetrack holes. When the through hole 18 is an oval hole, a kidney-shaped hole or a racetrack-shaped hole, the cross-sectional area of the through hole 18 is larger than that of the fastener, so that the fastener can move back and forth in the through hole 18, namely, when the fastener passes through the through hole 18 and is locked in the cabinet body 4, the connecting part 21 drives the first connecting piece 1 to slide in the front-back direction in the mounting groove 41, and the front-back sliding of the first connecting piece 1 is not limited by the fastener, so that the second connecting piece 2 and the first connecting piece 1 are ensured to be assembled smoothly, and the laminate 5 is further mounted in the cabinet body 4.
The laminate 5 of the embodiment 1 of the present utility model is connected with the cabinet 4 through the connection assembly of the embodiment 1 to form a connection system, as shown in fig. 19-24, the connection system comprises the cabinet 4, the laminate 5, the first connection member 1 and the second connection member 2, wherein, a mounting groove 41 extending along the front-rear direction is formed on the left side inner wall or the right side inner wall of the cabinet 4; the laminate 5 is provided in the cabinet 4 and slides in the up-down direction, and a mounting hole 51 extending in the left-right direction is formed in a side of the laminate 5 opposite to the mounting groove 41; the first connecting piece 1 is slidably mounted in the mounting groove 41 and can slide along the front-rear direction, the outer cylinder part 22 is inserted in the mounting hole 51, and one end of the connecting part 21, which is away from the elastic part 23, extends out of the laminate 5 and is inserted in the connecting groove 11; when the laminate 5 is mounted in the cabinet 4, the connection portion 21 moves downward in the connection groove 11 as the laminate 5 slides downward with respect to the cabinet 4. When there is an error in the mounting position of the first connector 1 in the mounting groove 41 (or when there is a positional error in the second connector 2 on the laminate 5), the downward moving connector 21 will abut against the first adjusting surface 13 or the second adjusting surface 14, when the connector 21 moves downward in the connecting groove 11 and abuts against the first adjusting surface 13, the connector 21 will drive the first connector 1 to slide forward in the mounting groove 41, or when the connector 21 moves downward in the connecting groove 11 and abuts against the second adjusting surface 14, the connector 21 will drive the second connector 2 to slide backward in the mounting groove 41, so that the first connector 1 is adjusted to a proper position, so that the connector 21 moves smoothly to the lower side of the connecting groove 11, and the assembly process of the laminate 5 in the cabinet 4 is completed.
Further, after the assembly is finished, since the left and right sides of the laminate 5 are respectively attached to or near the left and right inner sides of the cabinet 4, during the installation process, the left and right sides of the laminate 5 are respectively abutted to the left and right inner sides of the cabinet 4, the inner side of the cabinet 4 drives the connecting portion 21 to retract into the outer cylinder portion 22, at this time, the elastic portion 23 is in a compressed state, the laminate 5 slides down in the cabinet 4 and aligns the connecting portion 21 above the notch of the connecting groove 11, when the connecting portion 21 moves to the notch of the connecting groove 11, the laminate 5 slides down further to cause a gap between the connecting portion 21 and the inner wall of the connecting groove 11, the elastic portion 23 drives the connecting portion 21 to extend outwards and enter the connecting groove 11, and when the laminate 5 moves down further, the connecting portion 21 moves down in the connecting groove 11, at this time, the connecting portion 21 may abut against the first adjusting surface 13 or the second adjusting surface 14, and the first connecting member 1 is driven to slide in the front-rear direction on the cabinet, or the position of the first connecting member 1 is not moved down, and the laminate 5 moves down to drive the connecting portion 21 to move down to the connecting portion 11 to the lower side of the connecting portion 11, and the laminate 5 is installed in the laminate 4.
After the installation, if the layer board 5 protrudes slightly in front of the cabinet body 4, the acting force can be applied to the layer board 5 to enable the first connecting piece 1 to move backwards, and the second connecting piece 2 and the layer board 5 can be indirectly moved backwards, so that the cabinet is more attractive.
When the laminate 5 needs to be detached from the cabinet body 4, an external force acts on the bottom of the laminate 5 to push the laminate 5 to move upwards, the moving laminate 5 drives the connecting portion 21 to move upwards in the connecting groove 11, when the connecting portion 21 abuts against the unlocking surface 12, the unlocking surface 12 drives the connecting portion 21 to retract gradually into the outer cylinder portion 22 so that the connecting portion 21 moves out of the connecting groove 11, when the connecting portion 21 moves out of the connecting groove 11 completely, the first connecting piece 1 and the second connecting piece 2 are separated from each other, the laminate 5 can slide along the front-back direction, and the laminate 5 is detached from the cabinet body 4.

In addition, the fixing member 3 'is added to achieve an attractive effect, so that the user considers that the first connecting member 1' is displaced on the fixing member 3', instead of being directly displaced on the cabinet 4, and when the first connecting member 1' and the fixing member 3 'are made of the same material (such as plastic material), the first connecting member 1' slides more smoothly.
It should be noted that, the structures of the cabinet 4 and the laminate 5 in the embodiment 2 are the same as the structures of the cabinet 4 and the laminate 5 in the embodiment 1, and specific structures are described in the embodiment 1, and redundant descriptions are omitted here.

It will be appreciated that, when the volume of the first connector 1' of the present embodiment 2 is the same as the volume of the first connector 1 of the above-described embodiment 1, since the volume of the fixing member 3' is larger than the volume of the first connector 1', the size of the mounting groove 41 of the cabinet 4 of the present embodiment 2 in the front-rear direction is larger than the size of the mounting groove 41 of the cabinet 4 of the above-described embodiment 1 in the front-rear direction to ensure that the first connector 1' slides on the fixing member 3' in the front-rear direction.
In some embodiments, as shown in fig. 25 to 27, the upper side wall of the fixing member 3' and/or the lower side wall of the fixing member 3' is formed with a connection port 32' communicating with the chute 31', the first connection member 1' is formed with a second boss 15', and a portion of the second boss 15' passes through the connection port 32' to protrude outside the fixing member 3 '.

After the first connecting piece 1 'is accurately installed in the installation groove 41 of the cabinet body 4, in order to further improve the connection firmness of the first connecting piece 1' on the cabinet body 4, a fastener is used to pass through the through hole 18 'and then connected on the cabinet body 4, so that the first connecting piece 1' is firmly locked on the cabinet body 4, and the first connecting piece 1 'is limited to be pulled out from the connection groove 11'.
Further, the perforations 18' are circular holes or oval holes or kidney-shaped holes or racetrack-shaped holes. When the through hole 18' is an oval hole, a kidney-shaped hole or a racetrack-shaped hole, the cross-sectional area of the through hole 18' is larger than that of the fastener, so that the fastener can move back and forth in the through hole 18', namely, when the fastener passes through the through hole 18' and is locked on the cabinet 4, the connecting part 21' drives the first connecting piece 1' to slide in the front-back direction, and the front-back sliding of the first connecting piece 1' is not limited by the fastener, so that the second connecting piece 2' and the first connecting piece 1' are smoothly assembled, and the laminate 5 is further installed in the cabinet 4.

When there is an error in the installation position of the first connector 1' in the sliding slot 31' (or when there is an error in the position of the second connector 2' on the laminate 5), the downward moving connector 21' will abut against the first adjusting surface 13' or the second adjusting surface 14', when the connector 21' moves downward in the connecting slot 11' and abuts against the first adjusting surface 13', the connector 21' will drive the first connector 1' to slide forward in the sliding slot 31' (corresponding to driving the first connector 1' to slide forward on the cabinet 4), or when the connector 21' moves downward in the connecting slot 11' and abuts against the second adjusting surface 14', the connector 21' will drive the second connector 2' to slide backward in the sliding slot 31' (corresponding to driving the first connector 1' to slide backward on the cabinet 4), so as to adjust the first connector 1' to a proper position, so that the connector 21' moves smoothly to the lower side of the connecting slot 11', and complete the assembly process of the laminate 5 in the cabinet 4.
Further, after the assembly is completed, since the left and right sides of the laminate 5 are respectively attached to or near the left and right inner sides of the cabinet 4, during the installation process, the left and right sides of the laminate 5 are respectively abutted to the left and right inner sides of the cabinet 4, the inner side of the cabinet 4 drives the connecting portion 21' to retract into the outer cylinder portion 22', at this time, the elastic portion 23' is in a compressed state, when the laminate 5 slides down in the cabinet 4 and aligns the connecting portion 21' to the upper side of the notch of the connecting groove 11', and when the connecting portion 21' moves to the notch of the connecting groove 11', the laminate 5 slides further down to allow a gap to exist between the connecting portion 21' and the inner wall of the connecting groove 11', the elastic portion 23' drives the connecting portion 21' to extend out and enter into the connecting groove 11', and when the laminate 5 moves further down, the connecting portion 21' moves down in the connecting groove 11', at this time the connecting portion 21' may abut against the first adjusting surface 13' or the second adjusting surface 14', and drives the first connecting member 1' to slide up in the sliding direction in the sliding groove 31', or the first connecting member 1' moves down the connecting portion 1' to the lower side of the laminate 5, and the installation process is completed. After the installation, if the layer board 5 protrudes slightly in front of the cabinet body 4, the acting force can be applied to the layer board 5 to enable the first connecting piece 1 'to move backwards, and indirectly enable the second connecting piece 2' and the layer board 5 to move backwards, so that the cabinet is more attractive.
When the laminate 5 needs to be detached from the cabinet body 4, an external force acts on the bottom of the laminate 5 to push the laminate 5 to move upwards, the moving laminate 5 drives the connecting part 21' to move upwards in the connecting groove 11', when the connecting part 21' is abutted to the unlocking surface 12', the unlocking surface 12' drives the connecting part 21' to retract gradually into the outer cylinder part 22', so that the connecting part 21' moves out of the connecting groove 11', and when the connecting part 21' moves out of the connecting groove 11', the first connecting piece 1' and the second connecting piece 2' are separated from each other, the laminate 5 can slide along the front-back direction, and the laminate 5 is detached from the cabinet body 4.

As shown in fig. 48 to 57, embodiment 3 of the present utility model discloses a connection assembly having a structure similar to that of the connection assembly of the above-described embodiment 1 or 2, which is different in that: the first connecting piece 1a is fixedly installed on the cabinet body 4, the second connecting piece 2a is slidably installed on the laminate 5, and thus the position of the second connecting piece 2a on the laminate 5 is adjusted by matching the first adjusting surface 13a or the second adjusting surface 14a of the first connecting piece 1a with the connecting part 21a of the second connecting piece 2a, so that the laminate 5 is smoothly installed on the cabinet body 4.
Specifically, as shown in fig. 48 to 54, a first fitting groove 42 is formed in the left inner wall or the right inner wall of the cabinet 4 by a drilling process, and a second fitting groove 52 extending in the front-rear direction is formed in the outer wall of the laminate 5, and the position of the first fitting groove 42 corresponds to the position of the second fitting groove 52. The connection assembly of this embodiment 3 includes a first connection member 1a and a second connection member 2a, a connection groove 11a is formed on a left side wall or a right side wall of the first connection member 1a, an inclined unlocking surface 12a is formed between an upper inner wall of the connection groove 11a and a groove bottom of the connection groove 11a, a first adjusting surface 13a gradually inclined backward is formed on a front inner wall of the connection groove 11a, a second adjusting surface 14a gradually inclined forward is formed on a rear inner wall of the connection groove 11a, the first adjusting surface 13a and the second adjusting surface 14a are disposed at opposite intervals, the first connection member 1a is fixedly mounted in a first mounting groove 42 of the cabinet body 4, for example, the first connection member 1a is fastened in the first mounting groove 42 by interference fit or adhesion. The second connecting member 2a includes a connecting portion 21a, a sliding portion 22a, and an elastic portion 23a provided in the sliding portion 22a, one end of the elastic portion 23a is connected to the sliding portion 22a, the other end of the elastic portion 23a is connected to the connecting portion 21a, the connecting portion 21a reciprocates and stretches relative to the sliding portion 22a through the elastic portion 23a, the sliding portion 22a is slidably mounted in the second fitting groove 52 of the laminate 5, and the sliding portion 22a slides in the second fitting groove 52 in the front-rear direction, and one end of the connecting portion 21a facing away from the elastic portion 23a is inserted in the connecting groove 11 a; wherein, the first adjusting surface 13a is used for driving the second connecting piece 2a to slide backwards when the connecting part 21a moves downwards and is abutted to the first adjusting surface 13 a; the second adjusting surface 14a is used for driving the second connecting piece 2a to slide forward when the connecting portion 21a moves downward and abuts against the second adjusting surface 14 a.
Note that, the unlocking surface 12a, the first adjusting surface 13a, and the second adjusting surface 14a of the first connector 1a of the present embodiment 3 are the same as the unlocking surface 12, the first adjusting surface 13, and the second adjusting surface 14 of the above embodiment 1, and the specific structure is referred to the description of the above embodiment 1, and the detailed description thereof is omitted here. The length dimension of the first fitting groove 42 in the front-rear direction is the same as the dimension of the first coupling member 1a in the front-rear direction so that the first coupling member 1a cannot move back and forth within the first fitting groove 42. The length dimension of the second fitting groove 52 in the front-rear direction is larger than the dimension of the second coupling member 2a in the front-rear direction so that the second coupling member 2a can slide in the front-rear direction within the second fitting groove 52. When the connecting part 21a sliding downwards is abutted to the first adjusting surface 13a or the second adjusting surface 14a in the process of installing the laminate 5 on the cabinet body 4, the first adjusting surface 13a or the second adjusting surface 14a generates thrust to the connecting part 21a of the second connecting piece 2a, so that the second connecting piece 2a is pushed to carry out position adjustment backwards or forwards in the second embedded groove 52, the connecting part 21a is ensured to smoothly move to the lower side wall of the connecting groove 11a, the installation of the laminate 5 is completed, the situation that the assembly is difficult due to the position error of the second connecting piece 2a on the laminate 5, the re-perforating is needed, the fault tolerance rate is high, and the cabinet body 4 or the laminate 5 is avoided to be replaced due to the perforating error is avoided.
In some embodiments, as shown in fig. 48, in order to fixedly mount the first connector 1a in the first fitting groove 42, at least one fastening protrusion 15a is formed on an outer sidewall of the first connector 1a, and the fastening protrusion 15a may have a reversed tooth structure or a bump structure, and a cross-sectional area of the first fitting groove 42 is equal to or slightly smaller than that of the first connector 1a, so that the fastening protrusion 15a on a surface of the first connector 1a is inserted into the first fitting groove 42 in an interference fit manner, so that the first connector 1a is fixed on the cabinet 4.
In some embodiments, since the first fitting groove 42 is formed by drilling, the first fitting groove 42 is generally a circular hole or a oval hole, and when the first fitting groove 42 is a circular hole, the first connecting member 1a is also correspondingly circular when viewed along the left side of the first connecting member 1a toward the right side of the first connecting member 1a, and specifically the first connecting member 1a is a cylinder or a truncated cone structure. At this time, since the first connector 1a has an axisymmetric structure, there is a possibility that an installation direction error (for example, an up-down direction installation is opposite) may occur when the first connector 1a is inserted into the first insertion groove 42, and for this reason, as shown in fig. 52, the positioning portion 16a is formed on the first connector 1a of the present embodiment, and the positioning portion 16a may be located on an outer sidewall of the first connector 1 a; alternatively, as shown in fig. 49-51, the positioning portion 16a may be located on a side of the first connector 1a facing away from the notch of the connecting groove 11a, where the central axis of the positioning portion 16a is not collinear with the central axis of the first connector 1a, so that the positioning portion 16a is eccentric to the first connector 1 a. The positioning portion 16a may have a cylindrical structure extending in the front-rear direction or a cylindrical structure extending in the left-right direction. The cross-sectional area of the positioning portion 16a may be smaller than the cross-sectional area of the first connecting member 1 a. The positioning portion 16a may be formed as a plastic member of an integrated structure with the first connecting member 1a through an injection molding process. Correspondingly, a positioning hole communicated with the first embedded groove 42 is correspondingly processed on the inner side wall of the cabinet body 4, and the positioning hole is used for accommodating the positioning part 16a. The positioning part 16a and the positioning hole are matched and positioned, so that the first connecting piece 1a is ensured to be accurately installed in the first embedded groove 42, and the problem that the installation direction of the first connecting piece 1a on the cabinet body 4 is wrong is avoided.
In some embodiments, as shown in fig. 48, 49, 52 and 54, in order to improve the tensile force bearing capacity of the laminate 5 and the cabinet 4 in the left-right direction by the first connector 1a and the second connector 2a, a connection boss 211a is formed at one end of the connection portion 21a of the embodiment 3 facing away from the elastic portion 23a, and the connection boss 211a is inserted into the connection groove 11 a; a fastening flange 17a is formed on the lower inner wall of the connection groove 11a, and the fastening flange 17a cooperates with the connection boss 211a to limit the connection boss 211a to be pulled out or removed from the connection groove 11 a.

In other embodiments, the outer peripheral side wall of the first connecting member 1a is smooth and planar, the fastening flange 17a is not provided on the inner side wall or notch of the connecting groove 11a, the portion of the connecting portion 21a inserted into the connecting groove 11a is polished rod, and the tensile force bearing capability between the first connecting member 1a and the second connecting member 2a along the left-right direction is poor, so that the laminate 5 and the cabinet 4 are easily separated from each other along the left-right direction due to the transverse tensile force.
In some embodiments, as shown in fig. 53 and 54, a third protrusion 221a is formed on the upper side wall and/or the lower side wall of the sliding portion 22a of embodiment 3 of the present utility model. Specifically, the upper side wall of the sliding portion 22a is formed with a third protrusion 221a, or the lower side wall of the sliding portion 22a is formed with a third protrusion 221a, or both the upper and lower side walls of the sliding portion 22a are formed with third protrusions 221a.

The working principle of the third protrusion 221a in embodiment 3 is referred to the working principle of the first protrusion 15 in embodiment 1, and the detailed description is omitted herein.
In some embodiments, since the second fit groove 52 is machined by a drilling process, the second fit groove 52 is generally machined as a racetrack groove or a kidney-shaped groove. Correspondingly, the shape of the sliding portion 22a is the same as that of the second fitting groove 52, that is, as shown in fig. 55, the sliding portion 22a is also in a racetrack shape or a oval shape when viewed in the left-right direction, and the upper side wall and the lower side wall of the sliding portion 22a are respectively in a plane shape, so that the upper side wall and the lower side wall of the sliding portion 22a are parallel to the upper side wall and the lower side wall of the second fitting groove 52, and the sliding portion 22a is ensured to slide smoothly in the front-rear direction in the second fitting groove 52, so that the whole second connecting member 2a slides smoothly in the second fitting groove 52. In other embodiments, the sliding portion 22a may have a circular or D-shaped shape in the left-right direction, and in this case, the second connector 2a may also slide in the front-rear direction in the second fitting groove 52, so that the sliding stability is relatively general.

When there is an error in the installation position of the second connecting member 2a in the second fitting groove 52 (or when there is an error in the position of the first connecting member 1a on the cabinet 4), the downward moving connecting portion 21a will abut against the first adjusting surface 13a or the second adjusting surface 14a, when the connecting portion 21a moves downward in the connecting groove 11a and abuts against the first adjusting surface 13a, the first adjusting surface 13a will drive the second connecting member 2a to slide backward in the second fitting groove 52, or when the connecting portion 21a moves downward in the connecting groove 11a and abuts against the second adjusting surface 14a, the second adjusting surface 14a will drive the second connecting member 2a to slide forward in the second fitting groove 52, so that the second connecting member 2a is adjusted to a proper position, so that the connecting portion 21a moves smoothly to the lower side of the connecting groove 11a, and the assembly process of the laminate 5 in the cabinet 4 is completed. After the installation, if the layer board 5 protrudes slightly in front of the cabinet body 4, the second connecting piece 2a can be moved backwards by applying a force on the layer board 5 so as to enable the layer board 5 to be moved backwards, so that the cabinet is more attractive.
