Abstract
The utility model relates to a tension mechanism. The tension mechanism provided by the utility model can solve the problems that the traditional tension mechanism in the prior art adjusts tension simply with a screw, and the positioning precision of a trolley is not accurate. According to the main points of the technical scheme, the tension mechanism comprises a left driven wheel, a left wheel supporting frame, a number of pressure springs and an adjusting plate; the whole left wheel supporting frame comprises two fixation plates and a connection bottom plate; the bottom parts of the two fixation plates are connected through the connection bottom plate; two concave parts are oppositely arranged on the fixation plate on one side of the left wheel supporting frame; the concave parts are in rotation connection with the left driven wheel; the other side of the left wheel supporting frame is fixed with the pressure springs; the top parts of all pressure springs are fixedly connected with the adjusting plate; and the bottom parts of the pressure springs are connected with the left wheel supporting frame. The tension mechanism provided by the utility model has dual adjusting modes, can improve the tension of a belt, and ensures the positioning precision of the moving trolley.
Description
Technical field
The utility model relates to printer accessory technical field, particularly a kind of strainer.
Background technology
Traditional strainer is only regulated tensile force by screw, positioning accuracy for dolly is inaccurate, such fixed form, be difficult to adjust precision, tightness can only tighten the screws the number of turns control, when feeling that cart stationary is not firm and unstable, regulate the also inaccuracy of losing time like this by manual type.
The utility model content
The purpose of this utility model is to solve existing traditional strainer and only regulates tensile force by screw, positioning accuracy for dolly is inaccurate, such fixed form, be difficult to adjust precision, the number of turns that tightness can only tighten the screws is controlled, when feeling that cart stationary is not firm and unstable, regulate by manual type, the also coarse problem of losing time like this provides a kind of belt tension that improved, the strainer of positioning accuracy when having guaranteed moving of car.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of strainer, comprise left driven pulley, the revolver bracing frame, several stage clips and adjustable plate, revolver bracing frame integral body comprises two fixed heads and is connected base plate, the bottom of described two fixed heads connects by connecting base plate, be relatively set with two recesses on the fixed head of described revolver bracing frame one side, described recess and left driven pulley are rotationally connected, the opposite side of described revolver bracing frame fixedly has stage clip, fixedly connected with adjustable plate in the top of all stage clips, the bottom of described stage clip is connected with described left bracing frame.Use stage clip to guarantee that the adjustable plate position can regulate automatically, the adjustable plate shift in position has improved belt tension, positioning accuracy when having guaranteed moving of car.
As preferably, described strainer also comprises two outer fixed heads, and the outside of described outer fixed head and described fixed head flexibly connects.Arrange like this, can nearly step joint belt tension degree by the relative position of regulating outer fixed head and fixed head.
As preferably, described strainer also comprises the driven pulley fulcrum, offers corresponding through hole on described outer fixed head and the described fixed head, and described driven pulley fulcrum passes through hole, and the end of described driven pulley fulcrum is provided with and screws nut.Arranging like this is a kind of simple device, can a nearly step save the belt tension degree by the relative position of regulating outer fixed head and fixed head.
As preferably, the bottom of described fixed head is provided with relative upper overturning, and the angle of described upper overturning and fixed head is 90 degree.Increase structural strength, protected left driven pulley.
As preferably, the bottom of described outer fixed head also is provided with relative following flange, and the angle of described flange down and fixed head is 90 degree.Increase structural strength, protected left driven pulley.
