[0002] At present, inner cone sleeves are widely used as ports for incoming and outgoing lines in medium and high pressure gas filling cabinets. The box wall is made of stainless steel. The inner cone sleeve is located inside the gas filling cabinet box. The outside of the box is connected to the inner cone sleeve through washers and bolts. The inner cone sleeve is used to connect the cable terminal. During installation, the bolts need to pass through the gasket hole, the stainless steel plate hole and the inner cone sleeve thread in turn to fix the gasket and the inner cone sleeve threads on both sides of the box wall.

[0003] However, due to the limited internal space of the box and the need to install multiple sets of bolts for positioning each inner cone sleeve, the positioning efficiency of the bolts and the bolt holes on the inner cone sleeve directly affects the installation efficiency of the inner cone sleeve; when installing with the existing method, multiple people are required to collaborate in the installation. One person needs to fine-tune the inner cone sleeve on one side of the stainless steel plate, and one person needs to fine-tune the gasket and the fastening bolts on the other side of the stainless steel plate. It takes two people to complete the installation, which has low positioning efficiency, increased labor costs, and affected installation efficiency.

[0004] Based on the above problems, it is necessary to design a quick installation device to improve the installation efficiency of the cone sleeve and the gasket. Summary of the invention

[0035] See also Figure 1-6 , a device for installing a cone sleeve in an inflatable cabinet, comprising a tray 2, a positioning member and a fixing device;

[0036] The plurality of positioning members are arranged on the pallet, and the positions of the positioning members correspond to the positions of the bolt holes on the built-in sleeves. The fixing device is arranged on the pallet and is used to fix the pallet on the wall of the inflatable cabinet.

[0037] When the positioning piece passes through the box wall of the inflatable cabinet and is positioned and connected with the inner cone sleeve, the projection area of ​​the tray along the axial direction of the inner cone sleeve covers part of the bolt holes of the inner cone sleeve.

[0038] In some embodiments, the box wall of the inflatable cabinet is a rectangular box structure, the interior of which is used to fill compressed gas. The box is made of stainless steel, and mounting holes corresponding to the bolt holes of the inner cone sleeve are opened on the box wall.

[0039] In some embodiments, the positioning member is a positioning pin or a positioning stud 3, one end of which is fixedly connected to the tray, and the other end of which extends upward to be inserted into the mounting hole of the inner cone sleeve.

[0040] The positions of the plurality of positioning members can be a plurality of bolt holes that are sequentially adjacent to the inner cone sleeve, or a plurality of bolt holes that are spaced apart, but it needs to be ensured that the positions of the plurality of positioning members must correspond to the positions of the bolt holes. The length of the positioning member extending out of the tray needs to be greater than the length of the box wall of the box body, and can extend into the bolt hole to a certain depth.

[0041] The positioning stud 3 includes a positioning section and a threaded section 31. A threaded hole matching the threaded section 31 is provided on the pallet. The threaded hole is connected to the threaded section to achieve a fixed connection between the positioning stud 3 and the pallet.

[0049] Firstly, a stainless steel plate mounting hole 61 is opened on the stainless steel plate 6 of the wall of the gas filling cabinet according to the position of the inner cone sleeve.

[0050] Secondly, according to the model of the inner cone sleeve 7, three positioning studs are installed on the pallet, and the positioning studs are inserted into the stainless steel plate mounting holes 61. The positioning studs extend into the box body for a certain length, and at the same time, strong magnets are adsorbed on the stainless steel plate of the box body to fix the pallet.

[0051] Then, the bolt hole 71 of the inner cone sleeve is sleeved on the inside of the box body, and the strong magnet has a magnetic attraction effect on the inner cone sleeve to achieve the positioning of the inner cone sleeve.

[0052] Then, the gasket is put on the bolt, and the bolt 8 is installed on the mounting hole 61 of the stainless steel plate in the uncovered area of ​​the tray and connected with the bolt hole 71 of the inner cone sleeve.

[0053] It should be noted that the uncovered area of ​​the tray has at least two bolt holes 71 , and the inner cone sleeve can be fixed by connecting the two bolt holes 71 .

[0054] Finally, remove the tray and install bolts on the bolt holes of the inner cone casing corresponding to the tray area.

[0055] The present invention provides an installation device for an inner cone sleeve of an inflatable cabinet, which utilizes a gasket, a stainless steel plate and existing holes of the inner cone sleeve for positioning, and does not require new holes to be drilled, thereby achieving rapid positioning and installation. The installation device is fixed by means of a magnet or a suction cup, and the installation can be completed by one person, with simple operation; at the same time, it can meet the installation requirements of gaskets of various models of inner cone sleeves.
