Abstract
The utility model discloses a quick-open type high-pressure device locking mechanism comprising a cylinder, and a top cover, clamps, connecting blocks and screw rods, which are on the cylinder, wherein the top end of the cylinder and the bottom end of the top cover are respectively of flange structures with the same outer diameter and bulge structures with the same height; the clamps are arc-shaped; the two clamps are spliced around the flange structures so as to encircle the flange structures; a groove structure is formed in the inner arc side face of each clamp; the grooves are just embedded into the bulge structure on the cylinder and the bulge structure on the top cover to be jointed so as to form a common bulge structure; two ends of each clamp are fixed with the connecting blocks; two adjacent clamps are jointed with each other; the connecting blocks on the adjacent clamps are connected through a bolt. The clamps are fixed at the joint of the top cover and the cylinder in an embedded mode, and when the air pressure in the cylinder is extremely high, the top cover is applied with counter-acting force of the clamps due to upward tension, so that the joint of the top cover and the cylinder is tight, and the device is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of fast-open type high-potting still retaining mechanism.
Background technology
Because high-potting still in each test is, all need to open top cover, installation test cable, wastes time and energy.As the container that bears 35MPa high pressure, the reliable fastening particular importance of its top cover.Conventional method is with high-strength bolt, top cover to be tightened together with cylindrical shell, when test, constantly pressurize, bolt bears radial pull, along with pressure raises, bolt is constantly elongated, thereby affects sealing effectiveness, in the course of work, need continuous fastening bolt, because bolt pretightening is very large, each dismounting all needs just can complete with special mechanism, not only time-consuming but also bolt is also had compared with macrolesion.。
Utility model content
The utility model proposes a kind of fast-open type high-potting still retaining mechanism, can effectively avoid the high-pressure installation top cover of prior art to be directly fixed on cylindrical shell, the loosening bad problem of seal that causes of flange nut, by clip fixed roof and cylindrical shell joint embeddedly, in the time that inner barrel air pressure is excessive, top cover, because tension force is upwards subject to the reaction force of clip, makes the joint of top cover and cylindrical shell more airtight.
The utility model is specifically achieved through the following technical solutions:
A kind of fast-open type high-pressure installation retaining mechanism, comprises cylindrical shell, the top cover on cylindrical shell, and clip, contiguous block and screw rod, and the bead structure that external diameter is identical is made respectively with the bottom of described top cover in the top of described cylindrical shell, and is all provided with the bulge-structure of equal height; Described clip is circular-arc, at least two clips are stated bead structure around bead structures to form back wall residence, and the interior circular arc side of clip is provided with groove structure, the bulge-structure that described groove structure is just in time embedded on bulge-structure and the top cover on cylindrical shell engages on the rear common bulge-structure forming; The two ends of described clip are fixedly connected with piece, and two adjacent clips engage, and the contiguous block on adjacent clip is bolted.
Described clip bottom connects a roller by fixed support bar, and described cylindrical shell is provided with supporting track, and described roller is arranged on described supporting track;
The sidewall of described groove structure and the sidewall of described bulge-structure are all horizontal by the angle of 6～15 °.
The beneficial effect that the utility model produces is: can effectively avoid the high-pressure installation top cover of prior art to be directly fixed on cylindrical shell, the loosening bad problem of seal that causes of flange nut, under anticyclonic condition, can strengthen the degree of engagement of top cover and cylindrical shell, it is simple in structure, easy to operate, cost is low.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model plan structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in 1,2, a kind of fast-open type high-pressure installation retaining mechanism, comprises cylindrical shell 1, top cover 2 on cylindrical shell 1, and clip 3, contiguous block 4 and screw rod 5, the bead structure that external diameter is identical is made respectively in the bottom of the top of described cylindrical shell 1 and described top cover 2, and is all provided with the bulge-structure of equal height; Described clip 4 is circular-arc, at least two clips are stated bead structure around bead structures to form back wall residence, and the interior circular arc side of clip 4 is provided with groove structure, the bulge-structure that described groove structure is just in time embedded on bulge-structure and the top cover 2 on cylindrical shell 1 engages on the rear common bulge-structure forming; The two ends of described clip 3 are fixedly connected with 4, two adjacent clips 3 of piece and engage, and the contiguous block on adjacent clip 3 connects by bolt 5.
As preferred embodiment of the present utility model, clip 3 bottoms connect a roller 7 by fixed support bar, and cylindrical shell 1 is provided with supporting track 6, and roller 7 is arranged on described supporting track 6; The sidewall of groove structure and the sidewall of described bulge-structure are all horizontal by the angle of 6～15 °.When the utility model uses, clip 3 is nested on the structural bulge-structure of bead by the groove structure arranging on clip, at least plural clip surrounds the bead of cylindrical shell 1 and top cover 2, contiguous block on adjacent clip 3 connects by bolt 5, and the position of adjusting bolt keeps the diameter of a circle size in these clip besieged cities.In the time that bolt screws, the degree of depth that the groove structure of clip 3 is embedded into bulge-structure is larger, and top cover 2 and cylindrical shell 1 are firmly blocked, and reaches the object of locking.Otherwise, in the time that bolt unscrews, when clip unclamps, can unclamp yoke configurations and take off, top cover 2 and cylindrical shell just can be opened.In the process that screws or unscrew at bolt, roller rolls on supporting track 6 more simultaneously, and the function that guarantee screws normally or unscrews can also play the effect of supporting clip, handled easily on the basis that does not affect clip motion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
