Description

Technical Field

[0001] The present invention belongs to the field of gas meters, and particularly relates to an assembly method for a gas meter. Background Art

[0002] Gas meters are essential in every household. They are usually installed at the end of the gas pipeline to measure the amount of gas passing through. The structure of a gas meter generally includes a housing and a main unit. The main unit is the main part, which is used to connect to the gas pipeline and measure the amount of gas flowing through the pipeline. The main unit is arranged inside the housing to protect the main unit.

[0003] In order to install the main unit inside the housing, in the existing assembly method, limiting grooves are usually constructed on the inner sides of two opposite side walls of the housing respectively, and limiting pins adapted to the limiting grooves are constructed on two opposite sides of the main unit respectively. During assembly, the limiting pins on both sides of the main unit are respectively inserted into the corresponding limiting grooves. The limiting grooves limit and constrain the limiting pins, and the main unit is suspended inside the housing through the cooperation of the limiting grooves and the limiting pins. However, it is found in actual use that for the main unit installed by the above assembly method, when the main unit moves relative to the housing, especially during the process of transferring, transporting and installing the gas meter, the main unit is very easy to shake and vibrate, resulting in the deviation of the precision devices on the main unit from the set positions or even damage to the devices, seriously affecting the metering accuracy and service life of the gas meter. The reason lies in that on the one hand, there needs to be a dimensional difference between the limiting grooves and the limiting pins so that the limiting pins can be inserted into the limiting grooves, making it difficult for them to form a tight fit. On the other hand, there are errors in the forming process of the limiting grooves and the limiting pins, which also leads to the inability to achieve a tight fit between the two. Therefore, in actual products, it is very difficult for the limiting grooves and the limiting pins to achieve exactly a tight fit, and problems of the main unit moving relative to the housing are likely to occur. Summary of the Invention

[0004] The present invention provides an assembly method for a gas meter, aiming to solve the problem that the main unit of the gas meter assembled by the existing assembly method is prone to shaking.

[0005] To achieve the above object, the present invention provides an assembly method for a gas meter, including:

[0006] Step 1, install first constraint parts on both sides of the main unit of the gas meter, and install a support part at the bottom of the main unit of the gas meter;

[0007] Step 2, set second constraint parts on both sides of the gas meter housing, and the second constraint parts are used to cooperate with the first constraint parts for fixation;

[0008] Step three, the gas meter body enters the gas meter shell, the first constraint part and the second constraint part on both sides are connected with each other, the support part contacts the bottom of the shell, and the first constraint part and the second constraint part on both sides cooperate with the support part to form a three-point support.

[0009] In this solution, the first constraint part and the second constraint part are assembled together, and the bottom of the gas meter body is supported by the support part. The first constraint part and the second support part on both sides cooperate with the support part at the bottom, so that the gas meter body forms three-point support in the gas meter shell. The gas meter body can be more stably accommodated in the gas meter shell, avoiding the reduction of measurement accuracy caused by the shaking of the gas meter body in the gas meter shell.

[0010] Furthermore, in the assembly method in the prior art, the gas meter body and the gas meter shell are rigidly connected. When the shell collides or falls, the force will be directly transmitted to the body, which is very likely to reduce the accuracy of the precision devices on the body or even damage the precision devices on the body. Therefore, in step 1 of this solution, a shock absorbing component is assembled on the support column, and the shock absorbing component is used to contact with the inner bottom of the gas meter shell for shock absorption.

[0011] In this solution, a shock-absorbing component is installed on the supporting component, and the shock-absorbing component makes the shell and the main body have no hard contact, thereby avoiding the vibration directly transmitted from the gas meter shell to the gas meter main body. At the same time, the shock-absorbing component will deform when impacted, thereby absorbing the vibration of the gas meter main body, so that the gas meter main body is more stable in the gas meter shell.

[0012] Furthermore, in order to enable the shock-absorbing component to be stably assembled with the supporting portion, the shock-absorbing component of this solution is configured with a first connecting portion, and the supporting portion is configured with a second connecting portion, and the first connecting portion and the second connecting portion are interlocked and connected with each other.

[0013] By providing the first connection part and the second connection part, the first connection part and the second connection part are interlocked with each other, so that the shock absorbing component is stably installed on the supporting part, and the shock absorbing component is prevented from being separated from the supporting part.

[0014] Furthermore, in order to prevent the gas meter from shaking freely up and down, the gas meter housing of this solution includes an upper housing and a lower housing, and in step three, the upper housing presses the first constraint part downwards and fits it into the second constraint part.

[0015] In this solution, the support part props up the bottom of the gas meter body, and then the upper shell presses the first constraint part downward. The upper and lower ends of the gas meter body are restricted, preventing the gas meter from shaking freely in the shell.

[0016] Furthermore, in order to allow the shock-absorbing component to have deformation space to drive the gas meter body to absorb shock, the second constraint portion of the present solution is a limit groove, the first constraint portion is a limit pin, the limit pin is located at the upper end of the limit groove, and there is a margin below the limit pin for the limit pin to move up and down.

[0017] Through the movable margin in the limiting groove, the shock-absorbing component can drive the gas meter body to move up and down through deformation, and the shock-absorbing component absorbs the vibration of the gas meter during the deformation process.

[0018] Furthermore, in order to enable gas meter bodies of different models to adapt to this assembly method, the first constraint portion of this solution is constructed on the side cover. In the step one, side covers are respectively installed on both sides of the gas meter body, and the side covers on both sides clamp the gas meter body.

[0019] By arranging the first constraint part on the side cover, the first constraint part on the side cover cooperates with the second constraint part on the gas meter housing, and the side cover is connected to the gas meter body, so that different types of gas meter bodies can be accommodated between the side covers on both sides, and the adaptability is strong.

[0020] Furthermore, in order to enable the gas meter body to be connected to the side, the side covers on both sides of the present solution are assembled on the gas meter side through a restraining component, and a plurality of the restraining components are provided for respectively cooperating with different positions of the gas meter body.

[0021] By providing the constraint part, the side cover can be stably installed with the gas meter body of different models. At the same time, by providing multiple constraint parts, the connection between the side cover and the gas meter body is more stable.

[0022] Furthermore, in order to achieve the connection between the side cover and the gas meter body and avoid the use of screws which increases the assembly process, the constraint component in this solution is a limiting protrusion, which is used to abut against the gas meter body, thereby connecting the gas meter body and the side cover.

[0023] Furthermore, in order to make the bottom of the gas meter body more stable, in step 1 of this solution, a plurality of support parts are assembled and arranged at intervals, and the plurality of support parts are used to support different positions of the gas meter body.

[0024] In this solution, a plurality of support parts are arranged, and each support part is arranged at intervals. Therefore, each support part can support different sides of the gas meter body, making the gas meter body more stable.

[0025] Furthermore, in order to ensure that the four sides of the bottom of the support part can be supported, multiple support parts in this solution are respectively located at both ends of the bottom of the gas meter body, and the connecting line between the support parts at both ends and the connecting line between the first constraint parts on both sides are in a cross shape.

[0026] The two end support parts and the first constraint parts on both sides jointly support the four sides at the bottom of the support part, ensuring that the gas meter main body is more stable.

[0027] The beneficial effects of the present invention are as follows: By using the assembly method of this solution, the first constraint part and the second constraint part are assembled together to constrain both sides of the gas meter main body, and the support part constrains the bottom of the gas meter main body. The first constraint parts and the second constraint parts on both sides cooperate with the support part at the bottom to form a three-point cooperation, thereby enabling the gas meter main body to be stably placed inside the gas meter housing. At the same time, this assembly method is convenient for processing and assembly, that is, it solves the existing assembly problems and the assembly speed is very fast. Description of the Drawings

Detailed Embodiments

[0034] In order to make the objectives, technical solutions and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The embodiments are basically as shown in the attached Figure 1 to the attached Figure 3 A gas meter assembly method includes the following steps:

[0036] Step 1, install the first constraint parts 4 on both sides of the gas meter main body 1 respectively, and at the same time, a support part 6 is assembled at the bottom of the gas meter main body 1. The support part 6 can be assembled to the bottom of the gas meter main body 1 in a split manner, or can directly be constructed at the bottom of the gas meter main body 1.

[0037] Step 2: Second constraint parts 5 are respectively arranged on both sides of the gas meter housing 2. The second constraint parts 5 can be cooperatively connected with the first constraint parts 4, so that the side surface of the gas meter main body 1 is supported.

[0038] Step 3: Assemble the gas meter main body 1 into the gas meter housing 2. The first constraint parts 4 and the second constraint parts 5 on both sides are cooperatively connected with each other, and the supporting part 6 located at the bottom of the gas meter main body 1 contacts the inner bottom of the gas meter housing 2.

[0039] The first constraint parts 4 on both sides of the gas meter main body 1, the second constraint parts 5 and the supporting part 6 at the bottom of the gas meter main body 1 jointly form a three-point cooperation, so that the gas meter main body 1 assembled into the inside of the gas meter housing 2 is stably accommodated in the gas meter housing 2, and the gas meter main body 1 is prevented from moving.

[0040] In the prior art, the assembled gas meter housing and the gas meter main body are in hard contact, and the vibration of the gas meter housing will be directly transmitted to the gas meter main body. Therefore, in step 1 of this embodiment, a shock-absorbing component 7 is further assembled on the supporting part 6. The shock-absorbing component 7 contacts the inner bottom of the gas meter housing 2, avoiding direct hard contact between the gas meter main body and the gas meter housing. At the same time, the shock-absorbing component 7 can deform, so that the vibration amplitude of the gas meter main body 1 is smaller when being impacted by an external force, and the gas meter main body 1 is more stable.

[0041] The shock-absorbing component 7 is specifically a rubber pad, and the rubber pad is installed at the end of the supporting part 6. The supporting part 6 is a supporting column, which can support the rubber pad. At the same time, the supporting column can also restrain the rubber pad to prevent the rubber pad from moving under the action of an external force.

[0042] The shock-absorbing component 7 and the supporting part 6 are cooperatively connected through a first connecting part and a second connecting part. The first connecting part is a connecting pin, and the second connecting part is a connecting groove. The connecting pin can be inserted into the connecting groove, so that the shock-absorbing component 7 and the supporting part 6 are fixed together. The first connecting part and the second connecting part are respectively installed on the shock-absorbing component 7 and the supporting part 6. Specifically, the first connecting part can be installed on the shock-absorbing component 7 and the second connecting part can be installed on the supporting part 6; or the second connecting part can be installed on the shock-absorbing component 7 and the first connecting part can be installed on the supporting part 6.

[0043] In order to enable the gas meter main body 1 to be smoothly accommodated inside the gas meter housing 2, in this embodiment, the gas meter housing 2 includes an upper housing 201 and a lower housing 202. The upper housing 201 and the lower housing 202 are covered with each other, so as to form a closed cavity, and the inside of the closed cavity is used to accommodate the gas meter main body 1.

[0044] In the assembly of step three, the upper shell 201 presses the first constraint part 4 downward to be installed in the second constraint part 5. The upper end of the first constraint part 4 is restricted by the upper shell 201, so that the upper end of the gas meter body 1 is also restricted. At the same time, the support column 6 located at the bottom of the gas meter body 1 also supports the gas meter body upward. The support column 6 and the upper shell 201 cooperate with each other, so that the gas meter body 1 is stably accommodated in the gas meter shell, avoiding the gas meter body from freely moving up and down in the gas meter shell. Specifically, Figure 2 shown.

[0045] At the same time, due to the assembly requirements and the limitations of the manufacturing process, a certain amount of margin is usually left in the limit groove. Therefore, when the limit pin is pressed down and installed in the limit groove, the limit pin is located at the top of the limit groove. The margin of movement at the bottom of the limit groove can be used for the shock absorbing component to deform, thereby driving the gas meter body 1 to move up and down, absorbing the vibration of the gas meter body 1.

[0046] In this embodiment, the first constraint portion 4 is constructed on the side cover 3. Therefore, in step 1, the side covers 3 need to be respectively installed on both sides of the gas meter body 1, so that the first constraint portion 4 is located on both sides of the gas meter body 1.

[0047] At the same time, the gas meter body 1 is clamped inside by the two side covers 3, so that gas meter bodies 1 of different models can be assembled, and the adaptability is stronger.

[0048] The side covers 3 on both sides are respectively assembled on the sides of the gas meter through the restraining components 301, and a plurality of restraining components 301 are provided. Each restraining component 301 can be matched and connected with different positions of the gas meter body 1, so that the connection between the side cover 3 and the gas meter body 1 is more stable.

[0049] The restraining component 301 may be specifically a limiting protrusion, which is arranged at the four inner corners of the side cover 3. The limiting protrusions at the four corners cooperate with each other to restrain the upper, lower, left and right sides of the gas meter body 1. The limiting protrusions on the side covers 3 on both sides restrain the two sides of the gas meter respectively, so that the side covers 3 on both sides can be fixedly connected to the gas meter body 1.

[0050] It should be noted that the limiting protrusions can be distributed in not only four corners, but also triangles, pentagons, etc., and are mainly used to fit with the side of the gas meter body 1.

[0051] Alternatively, the restraining component 301 may be replaced with screws, and the side cover 3 may be connected to the gas meter body 1 by screws.

[0052] In order to enable the support portion 6 to support the bottom of the gas meter main body 1 more stably, in the first step of this embodiment, a plurality of support portions 6 are assembled and arranged at intervals. Each support portion 6 can support different positions of the gas meter main body 1, thereby making the gas meter main body 1 more stable.

[0053] In this embodiment, a plurality of support portions 6 are respectively located at both ends of the bottom of the gas meter main body 1, and the connection line between the support portions 6 at both ends is in a cross shape with the connection line between the first constraint portions 4 on both sides, so that the four directions of the gas meter main body 1 are constrained and restricted.

[0054] The following is a more detailed description through specific embodiments: In this solution, the side covers 3 are installed on the front and rear sides of the gas meter main body 1, the first constraint portions 4 are provided on the side covers 3, and then the support portions 6 are provided at the bottom of the gas meter main body 1. The first constraint portions 4 located on both sides of the gas meter main body 1 and the support portions 6 located at the lower end of the gas meter main body 1 form a three-point cooperation, thereby enabling the gas meter main body 1 to be stably installed in the gas meter housing 2.

[0055] Embodiment 2

[0056] This embodiment is further improved on the basis of Embodiment 1, as Figure 4 shown. In this embodiment, a connection port 8 is further constructed at the top of the housing, and the connection port 8 is used for the assembly of the gas outlet pipe 9 of the gas meter main body 1. The connection port 8 and the gas outlet pipe 9 cooperate with each other to constrain the upper end of the gas meter main body 1. After the connection port 8 and the gas outlet pipe 9 are matched, a support point can be formed at the connection port 8 and the gas outlet pipe 9. The support point formed by the connection port 8 and the gas outlet pipe 9 cooperates with the other three support points to form a four-point constraint, ultimately making the gas meter main body 1 more stable and preventing the gas meter main body 1 from moving.

[0057] Embodiment 3

[0058] This embodiment is further improved on the basis of Embodiment 1, as Figure 5 shown. A support port 10 is provided on the side of the housing, and the support port 10 is used for the assembly of the observation portion of the gas meter main body 1. The observation portion is located outside the gas meter housing 2, and the observation portion and the gas meter main body 1 are fixedly connected through a connecting member 11, and the connecting member 11 is accommodated in the support port 10. The support port 10 is used for the connecting member 11 to pass through the housing and support the connecting member 11.

[0059] After the support port 10 supports the connecting member 11, a new support point is formed between the support port 10 and the connecting member 11. The support port 10 and the connecting member 11 cooperate with the remaining three support points, so that the gas meter main body 1 is more stable in the gas meter housing 2.

[0060] The observation tube is also provided with a connecting piece for connecting to the outside of the housing, so that the gas meter body connected to the observation part can be more stably accommodated inside the gas meter housing. The connecting piece is specifically a receiving groove for receiving the protrusion at the connection of the upper housing and the lower housing, so that the observation part is connected to the housing in a matching manner.

[0061] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
