[0002] The knife and fork rack of the dishwasher is used to load cutlery such as knives and forks. In order to facilitate users to place or take knives and forks, the knife and fork rack can be pushed and pulled on the inner tank of the dishwasher. The knife and fork racks on the market only have pulley limiters. During the push and pull process, the knife and fork rack will shake left and right or up and down, causing abnormal noise or jamming during the push and pull process, leading to user complaints. Utility Model Content

[0003] The utility model aims to provide a knife and fork rack limiting structure, wherein a slide rail is installed on a knife and fork rack body in a left-right and / or up-and-down limiting manner through a first limiting assembly, and when the knife and fork rack body is pushed and pulled, the slide rail is relatively limited on the knife and fork rack body, so as to prevent the knife and fork rack body and the slide rail from relatively moving left-right and up-and-down during the pushing and pulling of the knife and fork rack body, thereby avoiding the problem of the knife and fork rack body being pushed and pulled unsmoothly, solving the problem of the knife and fork rack body being prone to abnormal noise or jamming during the pushing and pulling of the knife and fork rack body, and avoiding user complaints.

[0006] The first limiting assembly includes a first wheel and a second wheel which are staggered and arranged on the cutlery holder body at an upper and lower interval, and an installation groove for an upper and lower limiting installation slide rail is formed between the first wheel and the second wheel to prevent relative up and down movement between the cutlery holder body and the slide rail.

[0007] An opening for guiding the slide rail to be inserted into the installation groove is formed at the upper and lower offset positions of the first wheel and the second wheel, so as to facilitate the assembly between the knife and fork rack body and the slide rail.

[0008] The slide rail comprises an upper surface of the guide rail, and when the first wheel contacts the upper surface of the guide rail, a first supporting point of the slide rail supporting the knife and fork holder body is formed.

[0009] The main body of the knife and fork holder is provided with a reinforcing support block, and when the reinforcing support block contacts the upper surface of the guide rail, a second support point of the slide rail supporting the main body of the knife and fork holder is formed.

[0010] The first limiting assembly includes a third wheel and a support member which are spaced apart from each other. An installation groove for an upper and lower limiting installation slide rail is formed between the third wheel and the support member. The slide rail includes an upper surface of the guide rail. When the third wheel contacts the upper surface of the guide rail, a third support point of the slide rail supporting the knife and fork holder body is formed.

[0011] One side of the support member is extended laterally toward the outside of the cutlery holder body to form a support bottom block, and one side of the support bottom block is extended upward toward the upper part of the cutlery holder body to form a limiting side block. When the slide rail is limitedly installed on the mounting groove, the slide rail is supported on the support bottom block, and a first limiting groove portion is formed between the outer side of the cutlery holder body and the limiting side block, and the left and right limiting portions of the slide rail are installed on the first limiting groove portion.

[0012] The support member is provided with a guide surface for guiding the slide rail to be inserted upward into the installation groove. The guide surface is an inclined surface or an arc surface, which is convenient for assembling the slide rail and the knife and fork holder body.

[0013] The second limiting assembly includes a first sliding stroke limiting portion and a second sliding stroke limiting portion which are spaced apart on the slide rail. When the knife and fork holder body slides to a corresponding position relative to the slide rail, a corresponding part of the first limiting assembly contacts the first sliding stroke limiting portion or the second sliding stroke limiting portion; when the knife and fork holder body is pulled outwardly to a corresponding position on the slide rail, the third wheel contacts the second sliding stroke limiting portion to prevent the knife and fork holder body from escaping from the slide rail; when the knife and fork holder body is pulled inwardly to a corresponding position on the slide rail, the first wheel contacts the first sliding stroke limiting portion to realize that the knife and fork holder body has a limiting structure in both the pushing and pulling process or in a stationary state.

[0014] A limiting covering edge is extended outward from one side of the knife and fork holder body to cover one side of the slide rail, and a second limiting groove portion is formed between the limiting covering edge and one side of the knife and fork holder body. When the slide rail and the knife and fork holder body are assembled, the left and right limiting positions of the slide rail are installed on the second limiting groove portion; the second limiting component portion of the slide rail is extended upward along the inner top wall of the second limiting groove portion, and the second limiting component portion contacts the inner top wall of the second limiting groove portion to form a fourth support point for the slide rail to support the knife and fork holder body.

[0015] The first supporting point, the second supporting point, the third supporting point and the fourth supporting point are arranged between the cutlery holder body and the slide rail at intervals in front and back, the cutlery holder body is stably assembled, and the bending deformation of the cutlery holder body is effectively prevented.

[0016] The beneficial effects of the utility model are as follows:

[0017] The slide rail is installed on the cutlery holder body in a left-right and / or up-and-down limit position through the first limit assembly. When the cutlery holder body is pushed and pulled, the slide rail is relatively limited on the cutlery holder body to prevent the cutlery holder body and the slide rail from relative left-right and up-and-down movement during the pushing and pulling process, thereby avoiding the problem of the cutlery holder body being pushed and pulled unsmoothly, solving the problem of the cutlery holder body being prone to abnormal noise or jamming during the pushing and pulling process, and avoiding user complaints.
