Embodiment 1
[0027] see Figure 1~3 , in an embodiment of the present invention, a preheating sealing device with a self-locking function includes a fixed plate 1, a sliding sleeve 3 passing through the fixed plate 1 and slidingly connected with it, a tooth plate 7 fixed on the lower part of the sliding sleeve 3, Rotate the worm screw 8 arranged below the fixed plate 1, the worm wheel 10 meshed with the worm screw 8, and the gear 11 fixedly connected with the worm wheel 10, wherein the upper rear side of the fixed plate 1 is fixedly connected to the connecting column 6, and the connecting column 6 The rear part is fixedly connected to the mounting plate 5, and the two ends of the worm 8 are respectively connected to the fixed plate 1 and the mounting plate 5 through bearings, and the adjustment wheel 9 for adjusting the rotation of the worm 8 is fixedly connected to the rear of the worm 8. Rotating the adjustment wheel 9 drives the worm screw 8 to rotate.
[0028] Further, the worm wheel ...
Embodiment 2
[0031] A method for using a preheating sealing device with a self-locking function, comprising the following steps:
[0032] Step 1, adjust, turn the adjusting wheel to drive the worm to reverse, and drive the tooth plate, sliding sleeve and sealing plug to retreat to the side closest to the fixed plate;
[0033] Step 2, inserting, aligning the sealing plug with the outer mouth of the pipe fitting, keeping the sealing plug coaxial with the pipe fitting, turning the adjusting wheel forward to drive the tooth plate, sliding sleeve and sealing plug into the pipe fitting;
[0034] Step 3, fix and adjust the sealing plug to continue to advance until the clamping block fits closely with the outer wall of the pipe fitting;
[0035] Step 4, check. After the clamping block is attached to the outer wall of the pipe fitting, swing the fixing column to check the shaking situation, which can be divided into the following two types:
[0036] Case 1, the fixed column cannot shake, indicatin...

Abstract
The invention discloses a preheating sealing device with a self-locking function and an application method thereof; and the device uses a rotated worm rod for driving a worm wheel to rotate so as to drive a gear for following rotation, and the gear drives a tooth plate and a slide sleeve to slide along a guide rod to finally drive a sealing plug to move so as to realize sealing and plugging of pipe fittings. A connecting column is fixedly connected to the upper part of the back side of a fixed plate; a mounting plate is fixedly connected to the back part of the connecting column; the two endsof a worm rod are connected to the fixed plate and the mounting plate through bearings; and the back part of the worm rod is fixedly connected with an adjusting wheel for adjusting rotation of the worm rod.
Description
technical field [0001] The invention relates to a sealing structure, in particular to a preheating sealing device with self-locking function and its application method. Background technique [0002] As the use conditions of mechanical products become increasingly severe, higher requirements are put forward for the use conditions of rubber sealing products, such as the use of rubber seals in aerospace, aviation industry, petroleum and mining industry, construction machinery and transportation industry, energy industry , often have to adapt to a wide temperature environment and harsh environments such as high pressure and sand and dust. [0003] Existing sealing components are very prone to stress yielding after preheating and expansion, leading to the problem of giving way and leakage, and there are great safety hazards in actual production and life. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned above in the background art, the pre...
