[0042] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0044] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figures 1 to 7 As shown, a dishwasher rack structure described in the present invention comprises a rack body 1, wherein the rack body 1 is spliced ​​by a plurality of vertical rods 12 and horizontal rods 11 to form a frame structure with a downward depression for placing tableware.

[0047] Specifically, the dishwasher of the present invention comprises at least an inner tank, and the two sides of the inner tank are symmetrically provided with guide rail 2 components. The preferred guide rail 2 component can be selected from a double-section ball guide rail 2 or a three-section ball guide rail 2, wherein the outer rail 22 of the guide rail 2 component is directly fixed to the side wall of the inner tank by means of screws or welding, and the inner rail 21 of the guide rail 2 component is connected to the shelf body 1, so that the shelf body 1 is fixed in the inner tank, and can be pulled out and pulled out in the inner tank at will. However, in the traditional fixing method of the shelf body 1 and the inner rail 21, the connecting block hook is bent and fixed to the shelf body 1, and then connected to the side wall of the inner rail 21 by means of screws or bolts, so that the shelf body 1 is installed and fixed in the inner tank. This connection method is not easy to disassemble and install the shelf body 1 for cleaning or replacement. In addition, after the shelf body 1 is screwed or bolted to the inner rail 21, it is easy to loosen after long-term use, so there are certain safety hazards in the process of pulling out the shelf body 1.

[0048] In order to overcome the above-mentioned defects, the present invention proposes corresponding improvements.

[0049] It comprises a connecting member 3, one side of which is provided with a clamping portion 31, which is clamped with the side wall of the guide rail 2 of the dishwasher; the other side is provided with a sliding connecting portion 32, which is sleeved with the vertical rod 12 of the shelf body 1, so that the shelf body 1 can move vertically up and down relative to the connecting member 3.

[0050] In the present invention, the connecting member 3 is provided with a clamping portion 31 and a sliding connecting portion 32 on opposite sides thereof, wherein the clamping portion 31 is detachably connected to the inner rail 21 of the guide rail 2, which is different from the original screw or bolt connection; in addition, the connecting member 3 is connected to the vertical rod 12 of the shelf body 1 through the sliding connecting portion 32, so that after the shelf body 1 is pulled out of the inner tank, the upper and lower positions of the shelf body 1 can be adjusted up and down to avoid the shelf body 1 causing obstacles to the disassembly action, and then the shelf body 1 can be quickly disassembled together with the connecting member 3. The overall disassembly action is fast and convenient, so that ordinary users can also disassemble the shelf body 1.

[0051] Further, the clamping portion 31 includes:

[0052] The clamping column 311 protrudes from the side wall of the connecting member 3 and extends toward the guide rail 2 of the dishwasher;

[0053] A clamping joint 312 is fixedly connected to the extended end of the clamping column 311, and the clamping joint 312 extends radially outwardly along the clamping column 311 and protrudes from the outer peripheral wall of the clamping column 311;

[0054] A first bayonet 4 is provided on the side wall of the guide rail 2 , and the bayonet column 311 at least partially extends into the first bayonet 4 . The outer diameter of the bayonet joint 312 is larger than the diameter of the first bayonet 4 to limit the connector 3 from passing through the first bayonet 4 laterally.

[0055] In the present invention, the clamping column 311 in the clamping part 31 is cylindrical and extends from the side of the connector 3 relative to the inner rail 21 of the guide rail 2 to gradually approach it. A clamping joint 312 protruding from the outer peripheral wall of the clamping column 311 is also provided at its extended end. The clamping joint 312 is cylindrical, wherein the clamping joint 312 can be welded or threadedly connected to the extended end of the clamping column 311. A first clamping hole 4 is provided on the side wall of the inner rail 21 of the guide rail 2, wherein during the clamping action, the clamping part 31 is extended into the first clamping hole 4, and since the outer diameter of the clamping joint 312 is larger than the caliber of the first clamping hole 4, after the clamping part 31 is clamped into the first clamping hole 4, when it moves in a direction away from the clamping joint 312, the clamping joint 312 will be restricted by the first clamping hole 4 and cannot be disengaged. That is, through the cooperation between the clamping column 311, the clamping joint 312 and the first clamping port 4 in the clamping portion 31, the fast connection between the connecting member 3 and the guide rail 2 is achieved, and at the same time, the possibility of the connecting member 3 falling off in the lateral direction after being connected to the guide rail 2 is prevented.

[0056] Furthermore, a bending portion 211 protruding from the surface of the guide rail 2 is provided on the side wall thereof, and the protruding distance is greater than or equal to the thickness of the clamping joint 312 . The first clamping port 4 is provided on the bending portion 211 .

[0057] In the present invention, the guide rail 2 can be formed with a bending portion 211 protruding from the surface of the inner rail 21 of the guide rail 2 by stamping a sheet metal part, wherein the portion of the bending portion 211 parallel to the surface of the guide rail 2 is provided with the first bayonet 4. In the specific assembly process, the clamping joint 312 is inserted from the portion of the bending portion 211 parallel to the side wall of the guide rail 2, and the clamping column 311 slides and extends on the first bayonet 4 to complete the clamping action. By setting the bending portion 211, the size relationship between the thickness of the clamping joint 312 and the protruding interval of the bending portion 211 can be used during assembly, so as to perform positioning during installation, and at the same time play a role of limiting, preventing the connector 3 from falling off from the inner rail 21 of the guide rail 2 during lateral movement.

[0058] Furthermore, since the connecting members 3 are arranged on both the left and right sides of the shelf body 1, the connecting members 3 are provided with clamping joints 312 which can prevent the first clamping openings 4 of the guide rails 2 from being laterally separated. Since the clamping joints 312 arranged symmetrically on both sides simultaneously play a limiting role, the freedom of the shelf body 1 to move left and right is limited, ensuring that the shelf body 1 will not shake during the pulling action.

[0059] Furthermore, the longitudinal section of the first bayonet 4 is L-shaped, and the transverse end of the first bayonet 4 extends transversely in the direction in which the shelf body 1 moves outward.

[0060] In the present invention, the first bayonet 4 extends downward from the top of the bent portion 211 to form a first bayonet a41 matching the outer diameter of the bayonet column 311, and then extends from the extended end of the first bayonet a41 in a direction perpendicular thereto to form a first bayonet b42, the diameter of the first bayonet b42 is smaller than the outer diameter of the bayonet joint 312, and the first bayonet a41 and the first bayonet b42 form an L-shaped bayonet shape. Due to the limiting effect of the bayonet joint 312 and the first bayonet b42, the freedom of the shelf body 1 to move left and right is effectively limited.

[0061] Furthermore, the direction in which the first bayonet b42 extends is consistent with the direction in which the drawer shelf body 1 moves forward. When the drawer shelf body 1 is drawn, the side wall of the clamping column 311 will always abut against the end side wall of the extended end of the first bayonet b42, thereby ensuring that when the drawer shelf body 1 is pulled, the entire inner rail 21 will slide relatively along the outer rail 22 or the middle rail.

[0062] Further, the sliding connection portion 32 at least includes,

[0063] The first sleeve 321 is disposed on a side of the connecting member 3 facing away from the clamping portion 31 , and the first sleeve 321 is slidably sleeved on the vertical rod 12 of the shelf body 1 .

[0064] In the present invention, a first sleeve 321 is provided on the side opposite to the mounting clamping portion 31 of the connector 3, wherein the opening direction of the first sleeve 321 is parallel to the vertical rod 12. The first sleeve 321 and the vertical rod 12 are clearance-matched, thereby ensuring that the shelf body 1 can slide up and down relative to the connector 3. After the first sleeve 321 is connected to the vertical rod 12 of the shelf body 1, when the shelf body 1 and the guide rail 2 need to be disassembled or installed, the clamping interface between the clamping portion 31 of the connector 3 and the guide rail 2 can be adjusted by lifting the shelf body 1 up and down, thereby facilitating the disassembly or installation of the shelf body 1.

[0065] Further, the first sleeve 321 includes,

[0066] The first strip-shaped opening 321a extends along the axial direction of the first sleeve 321 to both ends of the first sleeve 321, and the first strip-shaped opening 321a is communicated with the pipe opening of the first sleeve 321;

[0067] The two limiting plates 321 b extend symmetrically from two edges of the first strip-shaped opening 321 a to protrude from the outer peripheral wall of the first sleeve 321 , and a detachable connection structure is provided between the limiting plates 321 b and the connecting member 3 .

[0068] In the present invention, the first sleeve 321 is made of plastic material and has a certain elasticity. A first strip opening 321a is provided along the axial direction of the first sleeve 321, which is through and connected to the tube hole. The diameter of the first strip opening 321a is smaller than the tube diameter of the first sleeve 321, and the diameter of the first strip opening 321a is smaller than the rod diameter of the vertical rod 12 of the shelf body 1, so that when the connecting member 3 and the shelf body 1 are installed, the first strip opening 321a can be appropriately deformed due to the material of the first sleeve 321, and the first sleeve 321 can be sleeved in the vertical rod 12 of the shelf body 1.

[0069] The first strip opening 321a is provided with two vertical sidewalls with stopper plates 321b protruding from the outer peripheral wall of the first sleeve 321 along the tangent direction thereat, and the two stopper plates 321b are symmetrically arranged. A connection structure is provided between the stopper plates 321b and the connector 3, which can realize the connection between the connector 3 and the stopper plates 321b (i.e., the first sleeve 321).

[0070] Since the first sleeve 321 and the limiting plate 321b are connected in a detachable manner, when the connecting member 3 is installed on the shelf body 1, the first sleeve 321 can be installed first, and then assembled through the connection structure between the first sleeve 321 and the limiting plate 321b, so that the connecting member 3 is installed on the vertical rod 12 of the shelf body 1. Since the first sleeve 321 and the vertical rod 12 of the shelf body 1 are slidably connected, the upper and lower positions of the first sleeve 321 or the shelf body 1 can be adjusted at any time according to the actual assembly situation during installation, so as to facilitate the installation of the connecting member 3 on the shelf body 1.

[0071] Furthermore, the connection structure at least includes:

[0072] The claw 321c has a neck portion protruding outward from the connection with the limiting plate 321b, and a claw portion bending and extending laterally from the extended end of the neck portion;

[0073] The second bayonet 5 comprises a second bayonet a51 matching the shape of the claw portion and a second bayonet b52 extending upward from the upper end of the second bayonet a51 and matching the width of the neck.

[0074] In the present invention, the connection structure includes a second bayonet 5 with which the claw 321c can match. The second bayonet 5 is composed of a second bayonet b52 arranged vertically and a second bayonet a51 arranged horizontally, wherein the second bayonet a51 is located below the second bayonet b52, and the transition between the two is connected and arranged, and the whole is L-shaped. The neck of the corresponding claw 321c can slide on the second bayonet b52, and the claw of the claw 321c has the same shape as the second bayonet a51 and the claw can pass through the second bayonet a51 horizontally. During assembly, the claw of the claw 321c in the two limiting plates 321b in the first sleeve 321 corresponds to the second bayonet b52 and passes through it, and then slides upward, so that the opening formed by the claw and neck of the claw 321c is clamped on the side wall of the connector 3 on the same side as the clamping portion 31.

[0075] Furthermore, the connection structure also includes a limit block 321d, which is arranged on the limit plate 321b on the same side as the claw 321c. The maximum vertical length of the limit plate 321b and the claw 321c is equal to the sum of the vertical lengths of the second clamp a51 and the second clamp b52.

[0076] In the present invention, after the claw 321c is engaged with the second bayonet 5, a limiting block 321d is provided on the limiting plate 321b on the same side as the claw 321c. The limiting block 321d is located directly below the claw 321c, and the maximum distance of the vertical line between the two is equal to the vertical length in the second bayonet 5. After the claw 321c is connected to the second bayonet 5, there is still a degree of freedom to slide downward. At this time, due to the limiting effect of the limiting block 321d, it can be ensured that the first sleeve 321 will not slide in the second bayonet b52, thereby causing the occurrence of situations such as falling off.

[0077] Furthermore, a support portion 323 is provided on the top of the connecting member 3, extending from the connecting portion to a side close to the shelf body 1;

[0078] The shelf body 1 is provided with an abutment portion 33 protruding outward from the surface of the vertical rod 12 of the shelf body 1 or the cross bar 11 of the shelf body 1 is provided protruding from the surface of the vertical rod 12 of the shelf body 1 , and the support portion 323 can abut against the abutment portion 33 or the cross bar 11 .

[0079] In the present invention, the top of the connector 3 is provided with a support portion 323 extending along the transverse edge of the connector 3, and the support portion 323 has an extension length in the direction close to the shelf body 1, and the extension length exceeds half the diameter of the first sleeve 321. The middle part of the support portion 323 is provided with a limit opening recessed toward the plate surface of the connector 3, and the opening size of the limit opening along the transverse edge of the connector 3 is located between at least two vertical rods 12 in the shelf body 1, so as to work together with the first sleeve 321 to prevent the connector 3 from moving laterally relative to the vertical rod 12 of the shelf body 1, thereby ensuring the stability of the connector 3 connected to the shelf body 1.

[0080] The shelf body 1 is provided with an abutment portion 33 protruding from the surface of the vertical rod 12 of the shelf body 1. After the first sleeve 321 is sleeved on the vertical rod 12 of the shelf body 1, one side of the connector 3 is engaged with the inner rail 21 of the guide rail 2. After the overall installation of the shelf body 1 is achieved, the shelf body 1 slides to the position where the abutment portion 33 and the support portion 323 abut against each other under the action of its own gravity, and then stops sliding, thereby stabilizing the shelf body 1 at a set height position. The abutment portion 33 may also be the cross bar 11 of the shelf body 1. After being welded to the vertical rod 12, the cross bar 11 also protrudes from the surface of the vertical rod 12. When the shelf body 1 slides, it can also hover at a set height position through the abutment between the cross bar 11 and the support portion 323 of the connector 3.

[0081] Specifically, a plurality of abutment portions 33 or cross bars 11 spaced apart vertically are provided on the periphery of the shelf body 1. The connecting member 3 can be arranged on different vertical bars 12 of the shelf body 1 according to needs. By abutting against the abutment portions 33 or cross bars 11 at different heights, it can be ensured that the shelf body 1 can be suspended at different heights, thereby satisfying the adaptive adjustment of the shelf body 1 for different tableware or washing programs.

[0082] Furthermore, at least one second sleeve 322 is provided on a side of the connector 3 away from the first sleeve 321, and a second strip-shaped opening 322a is provided on the same side of the second sleeve 322 and the first sleeve 321, and the opening size of the second strip-shaped opening 322a is greater than or equal to the rod diameter size of the vertical rod 12 of the shelf body 1. When the connector 3 is connected to the shelf body 1, the second sleeve 322 can be pre-engaged with the vertical rod 12 of the shelf body 1 to achieve pre-positioning of the connector 3 on the shelf body 1.

[0083] In addition, when the diameter of the second sleeve 322 is larger than the rod diameter of the vertical rod 12 of the shelf body 1, a limiting groove 322b is provided in the tube hole of the second sleeve 322, and an inner sleeve 324 is sleeved in the second sleeve 322, and the inner sleeve 324 can be made of rubber material.
