[0026] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0027] The present application discloses an explosion-proof flexible pipe joint installation device.

[0028] Embodiment 1

[0029] Reference Figure 1 and Figure 2The anti-explosion flexible pipe structure mounting device comprises an outer ring 1, a positioning block 2, a first arc plate 3, a second arc plate 4 and a pressing screw 5. The positioning block 2 is embedded on the circumferential outer wall of the outer ring 1, the end face of the positioning block 2 towards the center of the outer ring 1 is provided with a threaded hole 21, and the pressing screw 5 is threadedly connected in the threaded hole 21. The circular arc protruding part of the second arc plate 4 is fixedly connected with the circumferential inner wall of the outer ring 1 and is located at the position opposite to the positioning block 2 on the outer ring 1. The circular arc protruding part of the first arc plate 3 is fixedly provided with a sleeve 31, and the end part of the pressing screw 5 can extend into the sleeve 31 and rotate in the sleeve 31. The two side walls of the outer ring 1 are fixedly provided with a reinforcing sheet 6, the positions of the two reinforcing sheets 6 are opposite, and the reinforcing sheet 6 is fixedly connected with the side wall of the second arc plate 4. The circular arc radii of the circular arc concave surfaces of the first arc plate 3 and the second arc plate 4 are the same.

[0030] After the anti-explosion pipe joint is inserted into the anti-explosion flexible pipe, the part connecting the anti-explosion flexible pipe is placed on the second arc plate 4, the first arc plate 3 is also placed on the flexible pipe, the pressing screw 5 is rotated, the end part of the pressing screw 5 is inserted into the sleeve 31 and the first arc plate 3 is pressed towards the second arc plate 4, thereby realizing the fastening and mounting of the anti-explosion flexible pipe and the joint connecting part. Not only the efficiency of the anti-explosion flexible pipe joint mounting combination is improved, but also the pressing and mounting of the anti-explosion flexible pipe and the joint of different sizes can be adapted, and the required space is relatively small. The reinforcing sheet 6 can effectively improve the firmness of the second arc plate 4.

[0031] Reference Figure 1 In the embodiment, the outer ring 1 is the outer ring of a waste bearing, and the positioning block 2 is a nut. The combination of the outer ring 1 and the positioning block 2 is formed by cutting the bearing outer ring to form a region in which the nut can be placed and then welding the nut. The first arc plate 3 and the second arc plate 4 are formed by cutting the inner ring of a waste bearing into two halves, and the second arc plate 4 is welded on the outer ring 1. The sleeve 31 is welded on the first arc plate 3. The reinforcing sheet 6 is formed by cutting a metal gasket into two halves, and is welded on the outer ring 1 and fixedly welded with the first arc plate 3.

[0032] By cutting and welding the waste bearing, the anti-explosion flexible pipe joint mounting tool is realized, which not only can turn waste into treasure, but also can be adapted to the size of the flexible pipe for on-site production, and more importantly, the production cost is effectively reduced.

[0033] Embodiment 2

[0034] Reference Figure 3 The difference between the embodiment 2 and the embodiment 1 of the present application is that the sleeve 31 is sleeved on the end part of the pressing screw 5 and is rotatably connected with the pressing screw 5.

[0035] In this way, the first arc plate 3 and the pressing screw 5 can move integrally, and the first arc plate 3 does not need to be additionally held. The probability of loss of the first arc plate 3 is reduced, and the convenience of use is improved.

[0036] The embodiments of the present specific implementation are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
