[0035] The utility model provides an assembly fixture, such as Figure 2 and Figure 5 As shown, it includes a base plate 1 and at least two positioning members; the positioning members are fixedly arranged on the same side of the base plate 1 and are arranged in parallel; a stepped groove 4 is arranged on the upper part of the opposite side of the adjacent positioning members, and the two stepped grooves 4 constitute a rectangular installation space.

[0036] In this embodiment, after a plurality of positioning members are arranged on the bottom plate 1 , a rectangular installation space is formed by the stepped grooves 4 on two adjacent positioning members, which is used to position the installation module at the bottom of the gas pipeline.

[0037] In this embodiment, the parameters of the step grooves 4 on two adjacent positioning members are the same, that is, the height and width of the horizontal plane are the same, so that the accuracy of positioning the installation module at the bottom of the gas pipeline is ensured by the uniformly arranged step grooves 4.

[0038] In an optional embodiment, the positioning member includes a connecting plate 2 and a plurality of positioning blocks 3 , and the stepped groove 4 is arranged on the positioning blocks 3 .

[0039] In this embodiment, multiple positioning blocks 3 are arranged in a straight line along the length direction of the connecting plate 2, and the stepped groove 4 is set on one side of the length direction of the connecting plate 2, so that the positioning blocks 3 on different positioning parts can correspond one by one, thereby forming an installation space through the stepped groove 4.

[0040] In this embodiment, the width of the positioning block 3 is consistent with the width of the connecting plate 2 , which can facilitate positioning of the positioning block 3 .

[0041] Specifically, in this embodiment, the connection between the positioning block 3 and the connecting plate 2 is an integral arrangement.

[0042] The integrated arrangement can ensure the connection strength and stability between the positioning block 3 and the connecting plate 2 .

[0043] It should be pointed out that in the present embodiment, the connection method between the positioning block 3 and the connecting plate 2 is an integrated setting, but it is not limited to this method of integrated setting. It can also be other fixed connection methods, such as welding, riveting, bolt connection, clamping, etc., as long as it can achieve fixed connection between the positioning block 3 and the connecting plate 2 and ensure stability and position accuracy during connection.

[0044] In an optional embodiment, the positioning block 3 is provided with a penetrating upper mounting hole, and the base plate 1 is provided with a corresponding lower mounting hole.

[0045] In this embodiment, an upper mounting hole is provided on the positioning block 3 , and a lower mounting hole is provided on the base plate 1 . The fixing bolt passes through the upper mounting hole and is inserted into the lower mounting hole, so as to achieve the purpose of mounting the positioning member on the base plate 1 .

[0046] In this embodiment, a countersunk hole is provided at the end of the upper mounting hole, and the end of the fixing bolt can be screwed into the countersunk hole, thereby preventing the fixing bolt from being exposed and affecting the operation, and also improving the aesthetics of the assembly fixture.

[0047] In an optional embodiment, the upper mounting holes are waist-shaped holes; and all the waist-shaped holes are arranged in parallel.

[0048] In this embodiment, the upper mounting hole is set as a waist-shaped hole, and the length direction of the waist-shaped hole is consistent with the width direction of the connecting plate 2, so that it is convenient to adjust the spacing between adjacent positioning parts, so that the assembly fixture can be suitable for different installation modules, thereby improving the application range of the assembly fixture.

[0049] In an optional embodiment, the lower positioning hole 6 is a threaded hole.

[0050] In this embodiment, after the lower positioning hole 6 is set as a threaded hole, when the positioning member is fixed to the base plate 1 by fixing bolts, no nuts are required for fixing, which simplifies the fixing method, facilitates the installation operation, and improves the installation efficiency.

[0051] In this embodiment, the lower positioning hole 6 is a blind hole, that is, the fixing bolt passes through the upper positioning hole 5 and is directly threadedly connected to the lower positioning hole 6 , and the end of the fixing bolt is not exposed from below the base plate 1 .

[0052] It should be pointed out that the lower positioning hole 6 can also be set as a through hole, as long as it is a threaded hole that can be threadedly connected with the fixing bolt.

[0053] In an optional embodiment, the lengths of the positioning blocks 3 on the same positioning member along the length direction of the positioning member are not completely the same.

[0054] In this embodiment, the length of the positioning block 3 is set differently according to different installation modules, and can be completely the same, completely different, or partially the same and partially different.

[0055] In an optional embodiment, the intervals between adjacent positioning blocks 3 on the same positioning member are the same.

[0056] In this embodiment, the distances between adjacent positioning blocks 3 on the same positioning member are the same, which can facilitate positioning of the positioning blocks 3 .

[0057] It should be pointed out that the distance between adjacent positioning blocks 3 can be adjusted according to actual needs to improve the applicability of the positioning member.

[0058] In an optional embodiment, the stepped grooves 4 are provided on opposite sides of the positioning block 3 .

[0059] In this embodiment, each positioning block 3 is provided with two stepped grooves 4, and the two stepped grooves 4 are symmetrically arranged relative to the positioning block 3, so that the positioning block 3 does not need to be installed in a specific order, thereby improving installation efficiency.

[0060] In an optional embodiment, there is a gap 7 between adjacent positioning members.

[0061] In this embodiment, a gap 7 is set between adjacent positioning members, that is, there is a gap 7 between the connecting plates 2, which can reduce the contact area between the positioning members and the mounting module at the bottom of the gas pipeline, thereby protecting the surface of the mounting module and reducing the probability of scratching the surface of the mounting module.

[0062] In this embodiment, the size of the gap 7 is set according to the actual size of the installation module, and is adjusted by the waist-shaped hole.

[0063] In an optional embodiment, the positioning member is made of metal.

[0064] In this embodiment, the positioning piece is made of metal, which can ensure the hardness of the positioning piece and facilitate processing.

[0065] It should be pointed out that in this embodiment, the material of the positioning piece is metal, but it is not limited to metal. It can also be other materials, such as hard plastic, as long as it can ensure the hardness and processing accuracy of the positioning piece and can effectively support the installation module.

[0066] Specifically, in this embodiment, the material of the positioning member is aluminum.

[0067] It should be pointed out that the material of the positioning part can be aluminum, but it is not limited to aluminum. It can also be other metal materials, such as single metals such as iron and copper, and it can also be alloy metals such as aluminum alloy and stainless steel. As long as the hardness and processing accuracy of the positioning part can be guaranteed and it can effectively support the installation module.
