Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, an airtight tool for a cylindrical plug includes an inner conduit 9; the main structure 4 and the pressure ring 2 are sleeved on the inner conduit; the handle is fixed on one side of the inner conduit, the sealing ring 7 is sleeved on the inner conduit, and the limiting part 8 is used for limiting the sealing ring, wherein the limiting part 8 can be but not limited to a baffle ring which is sleeved on the inner conduit and used for limiting the sealing ring.

Air inlet 11 and gas outlet 13 have been seted up respectively to the both ends of inside pipe, fixedly connected with trachea on the major structure 4, trachea and air inlet are not fixedly connected but are linked together, guarantee the gas tightness between the two when making trachea and air inlet link up mutually in the position, are close to the equal fixedly connected with cushion of one end of air inlet near the trachea at the one end of trachea and air inlet.

As shown in fig. 1-2, a pressing ring 2 is sleeved on one end of the inner conduit far away from the main body structure, and a handle capable of rotating relative to the inner conduit is connected to one end of the inner conduit far away from the air outlet. The connection mode between the inner catheter and the handle has two modes, one of which is as follows: a through hole 14 is radially formed in one end, far away from the air outlet, of the inner guide pipe, the handle is fixed on the inner guide pipe through the matching of a bolt and the through hole, and the handle rotates along the through hole to drive the pressing ring to move and fix towards one end of the main body structure along the inner guide pipe; the second is as follows: the one end fixedly connected with linkage plate 10 that the gas outlet was kept away from to inside pipe, offer the through-hole 14 that is used for rotating the connection handle on the linkage plate, the handle rotates along the through-hole and drives the clamping ring and remove and fix to the one end of major structure along inside pipe, the linkage plate can carry on spacingly to the clamping ring on the one hand, can connect the handle moreover. The two modes are that the pressing ring drives the main body structure to move a certain distance to one side of the sealing ring along the inner guide pipe by rotating the handle, so that the main body structure compresses the sealing ring, the compressed sealing ring can be in interference fit with the inner wall of the liquid cooling pipe, and the air tightness tool is connected with the air pipe and the liquid cooling pipe in a sealing mode.

As shown in fig. 3, the inner pipe is sleeved with a sealing ring which can be in interference fit with the inner wall of the liquid cooling pipe along the compression deformation of the inner pipe between the main body structure and the gas outlet, the inner pipe is fixedly connected with a limiting part 8 for limiting the sealing ring at one end close to the gas outlet, and the sealing ring can be in interference fit with the inner wall of the liquid cooling pipe after being compressed by the main body structure, so as to connect the tool and the liquid cooling pipe and seal the joint of the liquid cooling pipe and the tool.

There are two kinds of modes of setting between rotatory ring and the major structure, one of them: in the arrangement mode, the rotating ring can drive the main body structure to move along the inner guide pipe when the pressing ring moves towards one side of the main body structure; the second step is as follows: there is the rotatory ring 3 of cover on the inside pipe at one side threaded connection that the major structure is close to the clamping ring, in this kind of setting mode, through the threaded connection between rotatory ring and the major structure, can the corresponding formation variable that changes between clamping ring and the handle, thereby reach the deformation volume size of control sealing washer, ensure the sealed effect between inside pipe and the liquid cooling pipeline, internal tension promptly, simultaneously under the regulating action of rotatory ring to the clamping ring stroke, the deformation volume size of sealing washer can be controlled, make this device can be applicable to the liquid cooling pipe of different inner wall diameters to a certain extent.

The cover of inside pipe is equipped with sealed clamping ring 6 that is used for driving sealing washer compression deformation between major structure and sealing washer, under the mating reaction of sealed clamping ring and locating part 8, can be with sealed clamping ring compression deformation to seal the gas outlet and the linking department of liquid cooling pipeline mouth. The inner guide pipe comprises two end guide pipes which are connected through threads, and as shown in figures 2-3, the inner guide pipe is arranged into two sections which are connected through the threads, so that the whole air-tightness tool can be conveniently disassembled and assembled by workers, and the air-tightness tool can be conveniently machined and transported.

The utility model has novel structure and stable operation, when in use, as shown in figure 1 and figure 3, the air pipe is firstly matched with the main structure and is connected with the air inlet, then the main structure of the tool is manually held, the gas outlet 13 of the tool is aligned with the liquid cooling pipeline 15, and the sealing ring part is completely sleeved in the air inlet of the liquid cooling pipeline; the handle is moved downwards to 90 degrees from the vertical direction, relative movement between the sealing ring and the liquid cooling pipeline is kept in the process, meanwhile, the handle presses the pressing ring 2 to move downwards, the pressing ring presses the rotating body to drive the main body structure to press the sealing pressing ring downwards, the sealing pressing ring moves downwards to press the sealing ring to move downwards, and the sealing ring deforms and expands due to the fact that the sealing ring is blocked by the limited baffle ring in the downward movement process. Along with the combined extrusion of the sealing ring and the liquid cooling pipeline from the side wall direction, the tool body is fixed in the liquid cooling pipeline and cannot shake to be fixed, so that the gas of an external gas pipe is filled into the liquid cooling pipe, and the gas entering and exiting is prevented from leaking; after the tool is fixed on the liquid cooling pipeline, the steps of inflation testing and the like can be realized.

The utility model discloses a rotatory drive clamping ring of handle removes, and the removal journey that utilizes the rotatory front and back clamping ring relative inside pipe of handle to form is poor, and simultaneously under the mutually supporting between the frock structure, the handle rotation can make sealed clamping ring remove and compression seal circle makes its deformation, the utility model discloses simple structure, convenient operation can combine outside trachea and the effectual sealing of liquid cooling pipe, has improved follow-up accuracy to the test of liquid cooling pipe to a certain extent.
