The gas water heater is also called as a gas water heater, and refers to a gas appliance which takes gas as fuel and transfers heat to cold water flowing through a heat exchanger in a combustion heating mode so as to achieve the purpose of preparing hot water. In recent years, although air energy water heaters and solar water heaters are well developed as low-energy-consumption products, gas water heaters are still favored by users due to the characteristics of large water outlet quantity, stable temperature, instant use, higher safety and the like.

At present, the market for buying and selling the gas water heater is approaching to saturation, and when a user renews a household gas water heater, the gas water heater on the stock market is changed and purchased, which is a future trend. In the installation process of the gas water heater, firstly, a hole is punched in a wall surface on which the gas water heater needs to be mounted, then, a screw is screwed into the hole, then, an installation hole in an upper hanging plate of the gas water heater is hung on the screw, and after the gas water heater is stabilized on the wall surface, a screw is screwed into an installation hole in a lower hanging plate of the gas water heater, so that the left and right displacement of the gas water heater is limited, and the gas water heater is stabilized on the wall surface.

However, the positions and distances of the mounting holes of gas water heaters of different manufacturers and different models may be different, in this case, the mounting hole of a newly purchased water heater is likely to be mismatched with the mounting hole of an old water heater, the hole drilled for the old water heater on the wall surface is likely to be inapplicable to the new water heater, the new water heater needs to be re-drilled when being installed, the damage to the wall surface is aggravated, inconvenience is brought to the installer, and the labor cost for after-sale installation is increased.

Based on this, as shown in fig. 1 to 4, the utility model provides a connecting mechanism and a gas water heater, so as to alleviate the technical problems that when the gas water heater is replaced in some technologies, mounting holes of a new water heater and an old water heater are different in position, and the new water heater and the old water heater need to be re-perforated during mounting, so that a wall surface is damaged, and the mounting cost is increased.

The utility model provides a connecting mechanism which is used for being connected to a gas water heater 100, wherein the gas water heater 100 comprises a lower hanging plate 200, and the connecting mechanism comprises a connecting part and a first positioning hole 310; the connecting mechanism is connected to the lower hanging plate 200 through a connecting portion, the first positioning holes 310 are provided in a plurality, and the first positioning holes 310 are arranged on the connecting mechanism.

According to the embodiment of the utility model, the lower hanging plate 200 of the gas water heater 100 is connected with the connecting mechanism, the connecting mechanism is provided with the plurality of first positioning holes 310, when the gas water heater 100 is replaced, the mounting holes 220 on the upper hanging plate of the gas water heater 100 are hung on the used screws on the upper hanging plate of the old water heater, then the first positioning holes 310 matched with the holes on the wall surface are selected from the plurality of first positioning holes 310 based on the holes punched on the wall surface according to the positions of the mounting holes 220 on the lower hanging plate 200 of the old water heater, the screws are screwed into the matched first positioning holes 310, and the screws are screwed into the existing holes without re-punching. The technical problems that when the gas water heater 100 is replaced, the positions of the mounting holes 220 of the new water heater and the old water heater are different, and holes need to be punched again during installation, so that the wall surface is damaged, and the installation cost is increased are solved.

It should be noted that, in the installation process of the gas water heater 100, the gas water heater 100 is firstly hung on the wall through the upper hanging plate by screws, the screws bear the weight of the gas water heater 100, and the lower hanging plate 200 only plays a role of limiting left and right, so the shape of the first positioning hole 310 is not limited in the up-down direction, and can be a round hole, a square hole or a vertically extending long and narrow hole, and the like, and the gas water heater 100 can be limited left and right only after being fixed on the wall through the screws and the existing holes on the wall surface.

The first positioning holes 310 are symmetrically arranged on the connecting mechanism, because generally speaking, two mounting holes 220 on the lower hanging plate 200 are symmetrically arranged on the gas water heater 100, and the mounting holes 220 on the upper hanging plate are usually arranged on the central axis of the gas water heater 100, so that when the gas water heater 100 is hung on a wall surface and the connecting mechanism is installed, the holes drilled on the wall surface by the old water heater are also symmetrically arranged on the left and right sides relative to the central axis of the new gas water heater 100.

In this embodiment, the connection mechanism is a mounting plate 300, and a plurality of first positioning holes 310 are formed in the mounting plate 300. It should be noted that the connection mechanism may be a wire mesh or other structures, as long as the existing holes on the wall surface can be used to complete the left and right limiting of the gas water heater 100.

In this embodiment, there are multiple sets of the first positioning holes 310, each set of the first positioning holes 310 includes two symmetrically disposed rows of the first positioning holes 310, and each row of the first positioning holes 310 includes a plurality of first positioning holes 310 arranged up and down. Specifically, as shown in fig. 9, there are three groups of first positioning holes 310 in the present embodiment, that is, six rows of first positioning holes 310 that are bilaterally symmetric are shared on the mounting plate 300. In the installation process, two first positioning holes 310 which are symmetrical left and right are determined according to the existing opening on the wall, and screws are driven into the two first positioning holes 310 to the existing opening to complete the left and right limiting of the gas water heater 100.

It should be noted that the number of the first positioning holes 310 and the distance between the first positioning holes 310 in each group are determined according to the distance between the mounting holes 220 on the lower hanging plate 200 of the old water heater in the current stock market, and data in different periods are likely to be different according to market research, so the specific structure of the mounting plate 300 and the mounting holes 220 should be determined according to specific data.

As shown in fig. 5 to 8, according to the distance between the mounting holes 220 on the old water heater, that is, the distance between the existing holes on the wall surface, the vertical distance between the screws used by the upper hanging plate and the holes used by the mounting holes 220 on the lower hanging plate 200 of the old water heater is a0, the horizontal distance between the holes used by the two mounting holes 220 on the lower hanging plate 200 of the old water heater is B0, the vertical distance between the mounting holes 220 on the upper hanging plate of the new gas water heater 100 and the mounting holes 220 on the lower hanging plate 200 is a1, and the distances between the three groups of first positioning holes 310 are B1, B2 and B3 respectively from small to large.

In the installation process of the gas water heater 100, after the gas water heater 100 is hung on a wall through the upper hanging plate, the difference value delta H between A0 and A1 is obtained by comparing the sizes of holes formed in the gas water heater 100 and the wall, the position of the installation plate 300 on the lower hanging plate 200 is adjusted, the length of the installation plate 300 extending out of the lower hanging plate 200 is larger than the delta H, a first positioning hole 310 capable of being matched with the existing hole formed in the wall surface is formed in the installation plate 300, then a screw penetrates through the first positioning hole 310 to be nailed into the existing hole formed in the wall, the left and right displacement of the gas water heater 100 is limited, and finally the installation plate 300 is connected to the lower hanging plate 200 through a connecting part.

For example, as shown in fig. 7 and 8, in this embodiment, the left-right distance B0 between the existing holes on the wall surface is equal to the left-right distance B2 between the first positioning holes 310 of the middle group, so that the first positioning holes 310 matching the existing holes on the wall surface can be determined in the first positioning holes 310 of the middle group on the premise that the mounting plate 300 is connected to the lower hanging plate 200.

In this embodiment, as shown in fig. 10 and 11, the mounting plate 300 includes a first surface and a second surface opposite to each other, the first surface is provided with a recess facing the second surface, a protrusion 320 is formed on the second surface, and the protrusion 320 extends in the up-down direction. Specifically, the protrusion 320 functions as a reinforcing rib, and as a thin plate-shaped structure, the mounting plate 300 is easily bent and deformed during use, and the protrusion 320 can effectively reduce the deformation of the mounting plate 300. Preferably, the protrusion 320 is disposed at the center of the mounting plate 300, and the first positioning holes 310 are symmetrically disposed at the left and right sides of the protrusion 320.

Further, the protrusion 320 is provided with a first through hole 330. The first through holes 330 play a role in reducing weight and releasing stress; on the other hand, if the old water heater is installed through one mounting hole 220, only two holes located on the same vertical line are formed in the wall surface, and in this case, the screw can be screwed into the lower hole through the first through hole 330 to limit the gas water heater 100.

The utility model also provides a gas water heater 100, which comprises a lower hanging plate 200 and the connecting mechanism, wherein the connecting mechanism is connected on the lower hanging plate 200.

Specifically, as shown in fig. 4, a groove 210 is formed in the lower hanging plate 200, the groove 210 extends in the vertical direction, the connecting mechanism is disposed in the groove 210, and the left end and the right end of the connecting mechanism are abutted to the groove wall of the groove 210. Under the condition, the groove 210 and the connecting mechanism are matched to limit the relative displacement between the connecting mechanism and the gas water heater 100 in the left-right direction, so that the central axis of the gas water heater 100 is the central axis of the connecting mechanism, and the connecting mechanism can move up and down in the groove 210, so that an installer can adjust the up-down position of the first mounting hole 220 according to the delta H.

In this embodiment, as shown in fig. 3, two sides of the groove 210 are opened with mounting holes 220. This is so that when the user directly purchases a new water heater instead of changing the water heater, the wall has no existing opening, and the left and right limitation of the gas water heater 100 can be directly completed through the mounting hole 220.

In this embodiment, as shown in fig. 9 and 10, the connection portion is a first connection hole 340, the first connection hole 340 is plural, the plural first connection holes 340 are arranged up and down, the lower hanging plate 200 is provided with a second connection hole 230, and the second connection hole 230 is matched with the first connection hole 340 to connect the gas water heater 100 with the connection mechanism.

In the installation process, the screw passes through the second connection hole 230 and is screwed into the thread of the first connection hole 340, and after the screw is screwed, the nut is pressed on the wall surface of the lower hanging plate 200 at the second connection hole 230, so that the lower hanging plate 200 and the connection mechanism are relatively fixed.

Further, the plurality of first connection holes 340 have a plurality of columns, and each column of first connection holes 340 includes a plurality of first connection holes 340 arranged up and down; the number of the second connection holes 230 is the same as the number of the first connection holes 340, and the second connection holes 230 are in one-to-one correspondence along the vertical direction. Specifically, as shown in fig. 4, each second connection hole 230 is grouped with a plurality of first connection holes 340 in the same column, and after the height of the connection mechanism is determined, the second connection hole 230 is fixedly connected with the first connection hole 340 in the same position as the second connection hole 230. The connection between the connection mechanism and the lower hanging plate 200 is more stable due to the plurality of second connection holes 230, and the specific number of the second connection holes 230 can be determined according to the model and the installation environment of the gas water heater 100.

In this embodiment, as shown in fig. 4, the lower hanging plate 200 is provided with a plurality of second positioning holes 240, the plurality of second positioning holes 240 are divided into a plurality of groups, and each group of second positioning holes 240 includes two second positioning holes symmetrically disposed. When the heights of the A0 and the A1 are equal, the heights of the old water heater and the new gas water heater 100 are the same, the second positioning holes 240 with the intervals equal to the B0 can be directly selected on the lower hanging plate 200, a connecting mechanism does not need to be installed, and the time of installation cost is saved.
