Description
Technical field
The utility model relates to the accessory that a kind of peristaltic pump is used, and particularly relates to and is used for the roll wheel assembly that squeezing tube is used on a kind of peristaltic pump.
Background technique
Present domestic and international various roller extruding type peristaltic pumps are to utilize roller by the certain movement direction extruding elastic hose cavity that rolls, because the variation that the cavity distortion produces volume discharges fluid, and the formation negative pressure fluid outside the suction pump again when cavity restores to the original state.Existing roll wheel assembly is to install by the upper and lower support engaging of roller, in installation process, because the upper and lower support of roller mostly is symplex structure greatly, can fasten from different orientation when mounted, and when design fastens, require corresponding one by one fastening of roller locating column on the upper and lower support of roller.Existing roll wheel assembly causes setup error easily, does not have foolproof function.
Summary of the invention
The purpose of this utility model is that a kind of foolproof function that has will be provided, and fastens easy roll wheel assembly.
The utility model realizes that the technological scheme of above-mentioned purpose is, a kind of roll wheel assembly, comprise roller, roller upper bracket and roller lower support frame, all has the motor shaft axis hole on described roller upper bracket and the roller lower support frame, correspondence is provided with at least two roller locating columns on described roller upper bracket and the roller lower support frame, described roller housing is contained on the roller locating column and with the roller locating column and is rotatably assorted, described roller upper bracket interconnects with the roller locating column of roller lower support frame by corresponding setting, it is characterized in that: have the fool proof pin on the central boss of described roller lower support frame, have on the central boss of roller upper bracket with the corresponding rolling wheel lower support frame on fool proof at the fool proof hole that should cooperate; Have the fool proof hole on the central boss of perhaps described roller lower support frame, have on the central boss of roller upper bracket with the roller lower support frame on the fool proof pin that plugs together mutually of fool proof hole.
Has the fastening register pin on the roller locating column of described roller upper bracket, have on the roller locating column of described roller lower support frame and the corresponding fastening positioning hole that fastens the register pin corresponding matching, have the fastening positioning hole on the roller locating column of perhaps described roller upper bracket, have fastening register pin on the roller locating column of described roller lower support frame with corresponding fastening positioning hole corresponding matching.
Equal correspondence is provided with three roller locating columns on described roller upper bracket and the roller lower support frame.
All has stiffening rib on described roller upper bracket and the roller lower support frame, by the central boss that stiffening rib is positioned at.
The utility model is owing to have fool proof pin or fool proof hole on the central boss of described roller lower support frame; Have on the central boss of roller upper bracket with the roller lower support frame on fool proof pin or fool proof hole the fool proof hole or the fool proof pin that plug together mutually, cooperation by fool proof pin and fool proof hole, roller upper bracket and roller lower support frame are when fastening, can only fasten in the orientation of a regulation, otherwise dress is less than together, therefore, the utlity model has foolproof function, fasten easy.
