Description

Gas meter base of riveting fixed counter

Technical Field

The utility model relates to the technical field of gas meter production, in particular to a gas meter base for riveting a fixed counter.

Background

In the diaphragm type gas table field, the difference between the intelligent meter and the common meter lies in that the intelligent meter is internally provided with a circuit board, and as the intelligent meter is provided with the circuit board, the base structures of the intelligent meter and the common meter are also greatly different, and at present, the base adopted in the industry is fixed by a way of fixing the counter through a screw. Because the counter of the intelligent meter is connected with the circuit board through the sampling line to transmit signals, when the counter is fixed through the screw, the screw is often screwed on the sampling line of the counter due to the problem of manual operation, so that the sampling line of the counter is broken, the electronic metering performance of the meter is unstable, even the normal use of the meter is affected, the screw cannot see the sampling line after being screwed in, an operator cannot observe whether the sampling line is broken from the outside, the counter can only be tested after the counter is installed, if the test failure indicates that the sampling line is damaged, the counter needs to be detached, the counter is installed after the sampling line is replaced again, and time and labor are wasted; some screws are screwed on the sampling line and do not damage the outer skin of the sampling line, so that the test of the counter is not affected, but after the gas meter is used for a long time, the screws are always tightly propped against the sampling line, the gas meter can also be broken in the use process, a large hidden danger is left for the normal use of the gas meter, and the normal use of the gas meter is affected.

The counter is generally fixed by two screws, so that a certain material cost is increased, the labor cost is increased in the process of disassembling and assembling the counter, and meanwhile, the working efficiency of staff is also influenced.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a gas meter base for riveting and fixing a counter, which is convenient and quick to install the counter, reduces material cost and improves working efficiency.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows.

A gas meter base for riveting and fixing a counter comprises an installation bottom plate for installing the counter; the mounting bottom plate is provided with a buckle corresponding to the position of the mounting hole of the counter, the end part of the buckle is provided with a mushroom head for riveting and fixing the counter, and the center of the mushroom head is provided with a groove convenient to mount; the diameter of the inner end of the mushroom head is larger than that of a mounting hole on the counter; the distance between the inner end of the mushroom head and the mounting bottom plate is larger than the thickness of the mounting hole on the counter.

Further optimizing the technical scheme, the mushroom head is of a structure with a narrow outside and a wide inside.

Further optimizing the technical scheme, the length of recess is greater than the length of mushroom head.

According to the further optimized technical scheme, the groove is a U-shaped groove.

By adopting the technical scheme, the utility model has the following technical progress.

According to the utility model, the counter is riveted and fixed by using the buckle, and the counter can be fixed by directly pressing the buckle on the mounting bottom plate, so that the counter is conveniently and quickly mounted, the risk of damaging a sampling line by an electric screwdriver and a screw is avoided, and the material cost can be reduced.

Detailed Description

The utility model will be described in further detail with reference to the drawings and the specific embodiments.

The utility model provides a gas table base of riveting fixed counter, combines the shown in fig. 1 through 3, includes mounting plate 1 for install counter 2, is provided with buckle 3 on the mounting plate 1, and buckle 3 corresponds the position of mounting hole on counter 2, is used for fixed counter 2 on mounting plate 1.

The tip of buckle 3 is provided with mushroom head 4 for with counter riveting fixed on mounting plate 1, the diameter of the inner of mushroom head 4 is greater than the diameter of mounting hole on counter 2, and the distance between the inner of mushroom head 4 and mounting plate 1 is greater than the thickness of mounting hole on counter 2, and when the installation counter like this, the screens of the inner of mushroom head 4 are wider, can effectively fixed counter not drop.

A groove 5 is formed in the center of the mushroom head 4, when the counter 2 is installed, two ends of the mushroom head 4 incline towards the inside of the groove, the diameter of the mushroom head 4 is reduced, and after the mushroom head passes through an installation hole of the counter, the counter is riveted on the installation bottom plate 1.

The mushroom head 4 is the structure of outer narrow inside width, when the installation counter, presses down the counter, plays the cushioning effect when inwards at mushroom head 4 top both ends, more easily makes the counter install in place, and the back is accomplished in the installation, and the inner of mushroom head 4 rivets the counter on mounting plate.

The groove 5 is a U-shaped groove, the inner side of the groove is of an arc-shaped structure, the stress of the mushroom head is uniform, and the service life of the base of the gas meter is prolonged.

The length of the groove 5 is greater than the length of the mushroom head 4, and when the counter is installed, the inward inclination angle of the mushroom head is smaller, so that damage caused by excessive inward inclination of the mushroom head is effectively avoided, and the service life of the base of the gas meter is prolonged.

When the counter is installed, the installation hole on the counter is aligned with the buckle on the installation bottom plate, the counter is pressed to the installation bottom plate, the outer slope of the mushroom head plays a role in guiding, the outer end of the mushroom head is inclined to the groove in the pressing process, the diameter of the mushroom head is reduced, and when the installation hole of the counter passes through the mushroom head, the inner end of the mushroom head fixes the counter on the installation bottom plate. When dismantling the counter, operating personnel only need hold the mushroom head with one hand, and one hand lifts up the counter outwards, alright break away from the buckle with the mounting hole of counter, alright dismantle the counter after both sides all break away from, both have avoided the screw to damage the risk of sampling line, also can promote staff production efficiency greatly.

And the buckle is fixed on the mounting bottom plate, so that a counter is not required to be mounted by using screws, the number of parts is reduced, and the material cost is reduced.
