Description

Novel take transmission support of hidden contrary function of ending

Technical Field

The utility model relates to a gas table field specifically indicates a novel take hidden transmission support that ends function.

Background

The diaphragm gas meter is applied to the life of people for nearly 100 years. The air intake and exhaust metering is realized by driving a four-bar mechanism through the reciprocating swing of a flexible diaphragm; in the existing gas meters used in the market, a small check sheet is mostly arranged on a support, and a check plate is shifted through unidirectional rotation of a vertical wheel, so that the check plate slides against the wall of the vertical wheel under the action of gravity and positively passes through a check groove structure; when the anti-return plate rotates reversely, the tail part of the anti-return plate is clamped on the vertical wheel under the action of gravity when meeting the anti-return groove, so that the anti-return function is realized; when the product is inclined to a certain angle, the backstop function of the backstop plate loses the effect when the tail of the backstop plate loses the influence of gravity, and the backstop cannot normally carry out backstop work; and traditional check board is located the support outside, and impurity in the gas and steam direct flush can cause the non return system to disturb to cause non return system to break down easily. Therefore, a novel transmission bracket with a hidden type non-return function is provided.

Detailed Description

The following will further describe a novel transmission bracket with a hidden type backstop function according to the present invention with reference to the accompanying drawings.

Referring to fig. 1-4, the novel transmission bracket with a hidden type non-return function of the present embodiment includes a core body 1, a driving gear 2 mounted on the core body 1, and a bracket assembly 3 mounted on the core body 1; the device is characterized in that the bracket assembly 3 comprises a bracket body 31, an idle gear 32 which is arranged on the bracket body 31 and is meshed with the driving gear 2, and a vertical gear 33 which is arranged on the bracket body 31 and is meshed with the idle gear 32; a non-return plate 4 is also arranged in the bracket body 31 in a sliding way; the arc-shaped convex blocks 5 are arranged on the idle wheel 32, the non-return plate 4 is arranged in the support body 31 in a sliding mode, the mechanical type non-return mode that the non-return plate 4 is shifted by gravity instead of the original non-return mode that the non-return plate 4 is shifted by gravity is formed by matching the arc-shaped convex blocks 5 and the fixed columns, so that the non-return function of a product can be normally used at any angle, the non-return at 360-degree dead angle is really realized, the application range is wider, and the non-return effect; the non-return plate 4 is arranged in the support body 31 and is positioned at the bottom of the intermediate wheel 32 to form a hidden structure, so that impurities and water vapor in gas are effectively prevented from directly rushing, and the interference of the impurities and the water vapor on a non-return system is effectively reduced.

Further, as shown in fig. 2-3, the bracket body 31 is provided with a sliding groove 34 for slidably mounting the non-return plate 4, and the non-return plate 4 is provided with a waist-shaped groove 41; the intermediate wheel 32 is provided with a fixing rod 35, and the intermediate wheel 32 passes through the waist-shaped groove 41 through the fixing rod 35 and is movably mounted on the bracket body 31; fixing columns 42 matched with the arc-shaped bumps 5 are further arranged on two sides of the waist-shaped groove 41 on the non-return plate 4; the backstop plate 4 is slidably mounted in the bracket body 31 by the slide groove 34, and the backstop plate 4 is reciprocated left and right with the fixed rod 35 as a base point by the waist-shaped groove 41 provided in the backstop plate 4.

Further, referring to fig. 4, the arc-shaped projection 5 is provided with a guide surface 51 and a backstop surface 52; by arranging the guide surface 51 and the non-return surface 4 on the arc-shaped projection 5, when the intermediate wheel 32 rotates positively, the guide surface 51 on the arc-shaped projection 5 is contacted with the fixed column 42 and pushes the non-return plate 4 to move when the intermediate wheel rotates continuously, and after the intermediate wheel rotates 180 degrees, the guide surface 51 is contacted with the fixed column 42 on the other side of the non-return plate 4 and pushes the non-return plate 4 to do a return action; when the intermediate wheel 32 rotates reversely, the non-return surface 4 contacts the fixed column 42, and the fixed column 42 abuts against the arc-shaped projection 5 through the non-return surface 4, thereby stopping the reverse rotation of the intermediate wheel 32.

Further, as shown in fig. 2-3, a limiting protrusion 43 is further disposed on the non-return plate 4, and a limiting groove 36 adapted to the limiting protrusion 43 is further disposed in the sliding groove 34; the travel of the moving distance at both sides of the non-return plate 4 is limited by the arrangement of the limit bump 43 and the limit groove 36 on the sliding groove 34, so that the non-return function is prevented from being blocked due to the overlarge or undersize distance between the arc bump 5 and the fixed column 42 caused by the overrun of the moving distance of the non-return plate 4 in the sliding groove 34.

Further, referring to fig. 1-2, the bracket body 31 is of a bridge-spanning structure, and the bracket body 31 is mounted on the core body 1 through screws; through striding bridge structure's setting, increased support body 31's intensity to effectively avoided because of support body 31 leads to the condition emergence that the idle wheel 32 installation is not in place because of deformation, made the meshing between driving gear 2 and the idle wheel 32 be connected more accurately, the phenomenon of latch, gear hopout can not appear.

The utility model discloses a working process: referring to fig. 1-6, when the driving gear 2 drives the intermediate gear 32 to rotate positively, the intermediate gear 32 drives the arc-shaped protrusion 5 to rotate positively, the guide surface 51 contacts the fixed column 42 and forms a continuous thrust on the fixed column when the arc-shaped protrusion 5 rotates positively, so that the arc-shaped protrusion 5 drives the non-return plate 4 to move in a corresponding direction until the end point of the guide surface 51, i.e., the guide surface 51 is separated from the fixed column 42, and after the arc-shaped protrusion 5 rotates 180 degrees, the guide surface 51 contacts the fixed column 42 on the other side and pushes the non-return plate 4 to move in the corresponding direction, i.e., the non-return plate 4 returns; when the driving gear 2 drives the intermediate wheel 32 to rotate reversely, the intermediate wheel 32 drives the arc-shaped protrusion 5 to rotate reversely, and the non-return surface 4 of the arc-shaped protrusion 5 contacts the fixed column 42, so that the non-return effect is achieved on the intermediate wheel 32 through the matching of the non-return surface 4 and the fixed column 42, and the reverse rotation is avoided.

The scope of the present invention is not limited to the above embodiments and their variations. The present invention is not limited to the above embodiments, and other modifications and substitutions may be made by those skilled in the art.
