Abstract
The utility model relates to the technical field of PCB plate manufacturing, in particular to an air door connecting rod of a central vacuum cleaner, which comprises a connecting rod, a cylinder, a cylinder rod, a bearing, a retainer ring and an air door shaft. The air door shaft is arranged on the right of the connecting rod, the bearing is arranged on the left of the connecting rod, the bearing connects the connecting rod and the cylinder rod, the retainer ring is disposed at the connection position of the connecting rod with the bearing, and the air door shaft is of a rectangular shape. By designing the air door shaft of the air door connecting rod of the central vacuum cleaner into the rectangular shape, friction between the air door shaft and the connecting rod is avoided so as to protect the air door shaft when a whole air door shaft rotates, and the connecting rod can conveniently move with small friction so as to prevent the connecting rod from being snapped due to the fact that the bearing connects the connecting rod and the cylinder rod.
Description
Technical field
The utility model relates to pcb board material production technical field, especially a kind of central dust extractor throttle linkage.
Background technology
Nowadays when producing the production of pcb board material, all can use central dust extractor, throttle linkage in central dust extractor, original throttle linkage is to be rotated by cylinder rod pulling connecting rod, because axle of the air door is circular, the situation that rubs and can wear and tear later for a long time between axle of the air door and the connecting rod causes frictional resistance to increase, and the accident that axle of the air door is broken easily takes place, connecting rod can increase the weight of its burden because of the reason of frictional resistance, thereby causes connecting rod to be broken.
The utility model content
In order to overcome the deficiency that existing axle of the air door and connecting rod are easily broken: the utility model provides a kind of central dust extractor throttle linkage.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of central dust extractor throttle linkage, comprise connecting rod, cylinder and cylinder rod, bearing, back-up ring and axle of the air door, described connecting rod the right is provided with axle of the air door, the described connecting rod left side is provided with bearing, described bearing connects connecting rod and cylinder rod, the junction of described connecting rod and bearing is provided with back-up ring, and described axle of the air door is a rectangle.
The beneficial effects of the utility model are: the axle of the air door of this central dust extractor throttle linkage is designed to rectangle; the whole wind door-hinge is rotated; avoided the friction between axle of the air door and the connecting rod; protected axle of the air door; because bearing connects connecting rod and cylinder rod; connecting rod can easily be moved, and it is little to rub, and the protection connecting rod is not broken.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Among the figure 1, connecting rod, 2, cylinder, 3, cylinder rod, 4, bearing, 5, back-up ring, 6, axle of the air door.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is structural representation of the present utility model, a kind of central dust extractor throttle linkage, comprise connecting rod 1, cylinder 2 and cylinder rod 3, bearing 4, back-up ring 5 and axle of the air door 6, described connecting rod 1 the right is provided with axle of the air door 6, described connecting rod 1 left side is provided with bearing 4, described bearing 4 connects connecting rod 1 and cylinder rod 3, and described connecting rod 1 is provided with back-up ring 5 with the junction of bearing 4, and described axle of the air door 6 is a rectangle.
Connect connecting rod 1 and cylinder rod 3 by bearing 4 in this central dust extractor throttle linkage, axle of the air door 6 is designed to rectangle, cylinder 2 pulling connecting rods 1, because axle of the air door 6 is rectangles, can not produce friction between axle of the air door 6 and the connecting rod 1, reduce frictional resistance, after using for a long time, still can guarantee the operation that connecting rod 1 and axle of the air door 6 are complete.In the design of the junction of bearing 4 and connecting rod 1 back-up ring 5, the effect of this back-up ring 5 being arranged is that protection bearing 4 can not be subjected to the external force effect and touches, and guarantees that bearing 4 can use normally.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
