Abstract
The utility model discloses a high-precision multi-piece type linkage mechanism, which belongs to the technical field of air valves and comprises a first connecting plate and a second connecting plate, wherein the first connecting plate is hinged to the second connecting plate through a pin shaft; the mechanism uses two second connecting plates to clamp and place the two sides of the first connecting plate, adopts the pin shaft to limit, can realize double limiting effect with the jackscrew fixing mode travel of the bearing seat of the air valve blade, avoids loosening, furthest transmits the linkage mechanism, and ensures stable locking and fixing effect in swinging operation.
Description
Technical Field
The utility model belongs to the technical field of air valves, and particularly relates to a high-precision multi-piece linkage mechanism.
Background
In the structure of the air valve in the prior art, a plurality of blades of the air valve rotate to be in linkage, most of blade linkage structures are fixed and connected in series in a mode of connecting a connecting rod by using bolts and nuts, and due to gaps between the sizes of the bolts and the perforated positions, after shaking in the dead space can be generated in operation, power is transmitted to the linkage mechanism, the rotation angle and the force cannot be completely executed necessarily, and the rotation angle error phenomenon of shaft motion can occur. The nut loosens also can lead to the bolt to break away from in vibrations and operation, can't normal operating.
Disclosure of Invention
The utility model aims to provide a high-precision multi-piece type linkage mechanism, which uses two second connecting plates to clamp and place at two sides of a first connecting plate, adopts a pin shaft for limiting, can realize double limiting effects with a jackscrew fixing mode stroke carried by a bearing seat at a wind valve blade, avoids loosening, furthest transmits to the linkage mechanism, and ensures stable locking and fixing effects in swinging operation.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the high-precision multi-piece linkage mechanism comprises a first connecting plate and a second connecting plate, wherein the first connecting plate is hinged to the second connecting plate through a pin shaft, the second connecting plate is arranged on two sides of the first connecting plate to form a sandwich structure, the pin shaft sequentially penetrates through the second connecting plate, the first connecting plate and the second connecting plate, clamping grooves are formed in two ends of the pin shaft, and clamp springs are fixed in the clamping grooves.
Further, the first connecting plate is provided with a through hole far away from the hinged end and is used for connecting the blade.
The beneficial effects of the utility model are as follows:
1. two second connecting plates are used for clamping and are arranged on two sides of the first connecting plate, pin shafts are used for limiting, the effect of double limiting of the stroke of the bearing seat at the air valve blade in a self-contained jackscrew fixing mode is achieved, looseness is avoided, the transmission to the linkage mechanism is achieved to the greatest extent, and stable locking and fixing effects in swinging operation are guaranteed.
2. The two ends of the pin shaft are positioned by using grooves, and snap springs are arranged in the clamping grooves to limit the positions, so that the pin shaft is prevented from being separated to the greatest extent.

FIG. 2 is a schematic diagram of a high-precision multi-piece linkage mechanism provided by the utility model;
fig. 3 is a schematic side view of fig. 2 of a high-precision multi-plate linkage mechanism provided by the present utility model.
In the figure: 1. a first connection plate; 2. a second connecting plate; 3. a pin shaft; 4. clamping springs; 5. a clamping groove.
Detailed Description
For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.
Referring to fig. 1 to 3, the following describes the high-precision multi-disc linkage according to the embodiment of the present utility model in detail.
As shown in fig. 2, this high accuracy multi-disc type interlock mechanism includes first connecting plate 1, second connecting plate 2, first connecting plate 1 articulates on second connecting plate 2 through round pin axle 3, second connecting plate 2 all sets up at first connecting plate 1 both sides and forms sandwich structure, round pin axle 3 passes second connecting plate 2 in proper order, first connecting plate 1, second connecting plate 2, draw-in groove 5 has been seted up at the both ends of round pin axle 3, draw-in groove 5 inside is fixed with jump ring 4, the jump ring 4 of adoption is the high-strength carbon steel jump ring 4 that current market can purchase, use high-strength carbon steel jump ring 4 to carry out the anti-disengaging of both ends and fix, the mode of approaching the zero clearance also can make slewing mechanism's running force, furthest's transmission arrives interlock mechanism department, the jump ring 4 at both ends is spacing also can bring stable locking and fixed effect in swing operation.
And a through hole is arranged at the first connecting plate 1 far away from the hinged end and is used for connecting the blades.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
