Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof joints, in particular to a pluggable explosion-proof joint for mining. Background Art

[0002] Explosion-proof joints are made of copper alloy and brass nickel-plated. They are suitable for oil refining and petrochemical industries. Due to the good thermal conductivity of copper and high-quality stainless steel and the fact that they contain almost no carbon, the heat generated in a short period of time when the joints rub or collide with objects is absorbed and conducted. Another reason is that copper and stainless steel are relatively soft, and have good yield during friction and collision, and are not easy to produce tiny metal particles, so we can hardly see sparks, thus achieving an explosion-proof effect.

[0003] When the staff needs to connect two objects, they usually install two sets of explosion-proof joints through bolts and other structures. During the process of disassembly and installation, they cannot be installed quickly, which causes certain inconveniences during the connection and installation process. Utility Model Content

[0024] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0025] Embodiment 1:

[0026] The present application provides a pluggable explosion-proof joint for mining, comprising an explosion-proof joint body 1; mounting holes 2 are provided at equal intervals on the surface of the explosion-proof joint body 1, an adjusting mechanism 3 is installed inside the mounting hole 2, an insertion groove 4 is provided inside the adjusting mechanism 3, and fixing mechanisms 7 are provided at equal intervals on the groove wall of the butt joint 5;

[0027] The fixing mechanism 7 includes a placement slot 701, a fixing rod 702 and a spring 703. The placement slot 701 is provided on the slot wall of the insertion slot 4. The fixing rod 702 is installed inside the placement slot 701. The spring 703 is installed on the surface of the fixing rod 702. An insertion slot 4 is provided at one end of the adjustment block 301. A limiting slot 8 is provided on the other side of the slot wall of the insertion slot 4 corresponding to the placement slot 701. A docking tube 5 is provided on one side of the adjustment block 301. An insertion tube 501 is provided on one side of the docking tube 5. The insertion tube 501 is installed inside the insertion slot 4. Fixing holes 6 are provided on the surface of the insertion tube 501 at equal intervals. The size of the fixing holes 6 matches the size of one end of the fixing rod 702. A limiting block 9 is fixedly installed on one end of the fixing rod 702. The size of the limiting block 9 matches the size of the limiting slot 8. The cross section of the fixing rod 702 is a "dry" structure.

[0028] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the explosion-proof joint body 1 is spliced ​​with the butt joint 5, the length of one end of the explosion-proof joint body 1 can be adjusted by the adjustment mechanism 3. At this time, the personnel can insert the insertion tube 501 at one end of the butt joint 5 into the insertion groove 4, and the insertion tube 501 will squeeze one end of the limit block 9, and squeeze the fixing rod 702 above the limit block 9 into the placement groove 701. When one end of the fixing rod 702 corresponds to the fixing hole 6 on the surface of the insertion tube 501, the fixing rod 702 will pop up downward under the elastic action of the spring 703 on its surface, and the limit block 9 at the bottom of the fixing rod 702 can be inserted into the limit groove 8, so that the insertion tube 501 can be inserted into the butt joint 5. The inlet pipe 501 is installed into the inner cavity of the insertion groove 4, so that the butt joint pipe 5 and the explosion-proof joint body 1 can be quickly spliced ​​and connected into a whole, thereby making it convenient to splice and install the device. Through the setting of the fixing mechanism 7, the explosion-proof joint body 1 and the butt joint pipe 5 can be quickly plugged in and installed, and during the installation process, personnel do not need to use external tools to plug and unplug them. When personnel are disassembling the explosion-proof joint body 1 and the butt joint pipe 5, they pull the fixing rod 702 outward to separate the fixing rod 702 from the fixing hole 6, and quickly disassemble the explosion-proof joint body 1 and the adjustment block 301, thereby further ensuring the convenience of installation and disassembly during the use of the device.

[0029] Further, the adjustment mechanism 3 includes an adjustment block 301, a rotation slot 302 and a rotation rod 303. The inner side of the adjustment block 301 is provided with rotation slots 302 at equal intervals. The rotation slot 302 is rotatably mounted with a rotation rod 303. The rotation rod 303 is rotatably mounted in the inner cavity of the mounting hole 2.

[0030] Specifically, Figure 1 , Figure 2 As shown, when personnel connect the explosion-proof joint body 1 with the docking pipe 5, at this time, the personnel can rotate the rotating rod 303 and rotate the rotating rod 303 inside the mounting hole 2 and the adjustment mechanism 3, so as to quickly adjust the distance between the adjustment block 301 and the mounting hole 2, and then quickly adjust the length of one end of the explosion-proof joint body 1, which can facilitate the explosion-proof joint body 1 to splice and install two groups of pipes, thereby improving the applicability of the device to a certain extent.

[0031] Working principle: When the explosion-proof joint body 1 is spliced ​​with the butt joint 5, the length of one end of the explosion-proof joint body 1 can be adjusted by the adjusting mechanism 3. At this time, the personnel can insert the insertion tube 501 at one end of the butt joint 5 into the insertion groove 4, and the insertion tube 501 will squeeze one end of the limit block 9, and squeeze the fixing rod 702 above the limit block 9 into the placement groove 701. When one end of the fixing rod 702 corresponds to the fixing hole 6 on the surface of the insertion tube 501, the fixing rod 702 will pop up downward under the elastic action of the spring 703 on its surface, and the limit block 9 at the bottom of the fixing rod 702 can be inserted into the limit groove 8, and then the insertion tube 501 can be installed in the inner cavity of the insertion groove 4, so that the butt joint 5 and the explosion-proof joint body 1 can be quickly spliced ​​and connected into a whole.

[0032] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
