Technical Field
The utility model belongs to the technical field of it is explosion-proof, concretely relates to explosion-proof cable clamp of anti-cold flow type closely seals joint.
Background
The explosion-proof cable clamp tight sealing joint is an explosion-proof accessory used in cooperation with an explosion-proof cable, can be arranged at the joint of an explosion-proof cable port and explosion-proof electrical equipment, plays roles of leading in the cable and fixing the position, achieves the effects of sealing and explosion-proof, has the advantages of excellent explosion-proof performance, safe and reliable structure, simple and convenient installation, high protection grade and the like, is widely used in various places needing electrical safety explosion-proof, such as petroleum, chemical engineering and the like, and is particularly suitable for the places needing electrical explosion-proof of offshore platforms and ships. The existing explosion-proof cable clamp tight sealing joint is easy to cause the cold flow phenomenon of the cable when the explosion-proof cable is connected, wherein the cold flow is the deformation phenomenon that at normal temperature, solid such as plastic, rubber, metal and the like is deformed under load and can not recover the original shape after the load is removed. The cold-flow formed cable can reduce the insulativity and the protectiveness of the sheath layer, and destructive damage is generated to the cable, so that potential safety hazards are generated.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model provides an explosion-proof cable clamp of anti-cold flow type closely seals the joint.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides an explosion-proof cable of anti-cold flow type presss from both sides tight sealing joint, includes the armor cone, sets up in the connector body of armor cone outlet end, the outlet end of armor cone is connected with a flexible sealing washer, detachable is provided with the uide bushing in the inlet wire end of armor cone, the near-end diameter of uide bushing is greater than the distal end diameter of uide bushing.
Preferably, an armored cone ring is sleeved on the wire inlet end of the armored cone.
Preferably, the sealing ring comprises a conical sleeve matched with the armored cone and a cylindrical sleeve connected to the other end of the conical sleeve.
Preferably, a cone bushing is further arranged in the armor cone, the cone bushing is arranged on the inner side of the sealing ring, and the cone bushing and the sealing ring are coaxial.
Preferably, the cone bushing is conical formed by a plurality of blade gaps, a threading hole is formed in the far end of the cone bushing, and the diameter of the threading hole is equal to that of the cylindrical sleeve. The cylindrical sleeve can tightly cover the explosion-proof cable.

The beneficial effects of the utility model are embodied in: the sealing washer carries out inseparable cladding in order to reach the protecting effect to wearing the cable of locating in the sealing washer, and the cone bush can bear the impact that the inside explosion of cavity brought, and the cavity is worn out to the flame that can effectually avoid inside explosion to produce, and the further wearing to establish of cable of having assisted of uide bushing, the utility model discloses a sealing joint has prevented explosion-proof cable's cold flow, and the practicality is strong.
Drawings
FIG. 1: the structure of the utility model is schematically shown.
FIG. 2: the utility model discloses a section structure schematic diagram.
The sealing device comprises a connector body 1, a sealing ring 2, a conical sleeve 21, a cylindrical sleeve 22, a conical bushing 3, an armored cone 4, an armored conical ring 5, a middle connector 6, a guide sleeve 7, a second sealing ring 8, a bushing 9 and a locking nut 10.
Detailed Description
Following combination embodiment specifically explains the technical scheme of the utility model discloses a tight sealing joint of anti-cold flow type explosion-proof cable clamp, including armor cone 4, set up in the connector body 1 of 4 leading-out terminals of armor cone, the cover is arranged in the armor taper ring 5 of the inlet wire end of armor cone 4. The armored cone 4 and the armored cone ring 5 are arranged in a middle connector 6 of the sealing joint and are used for clamping and fixing the armored part of the armored cable under the combined action. The sealing joint further comprises a locking nut 10, wherein the locking nut 10 is consistent with the prior art, a lining 9 and a second sealing ring 8 are arranged in the locking nut 10, and the locking nut is connected to one end of the middle joint body 6 through threads.
The outlet end of the armored cone 4 is connected with a flexible sealing ring 2, in order to better guide the cable and assist the cable to enter the sealing ring 2, and a guide sleeve 7 is detachably arranged in the inlet end of the armored cone 4. The guide sleeve 7 is arranged in a cone shape or a bowl shape.
The sealing ring 2 comprises a conical sleeve 21 connected with the armored cone 4 and a cylindrical sleeve 22 connected with the other end of the conical sleeve 21. The proximal diameter of the guide sleeve 7 is larger than the distal diameter of the guide sleeve 7. In this implementation, the guide sleeve 7 is made of a PVC film.
In order to further achieve the purpose of explosion prevention, a cone bushing 3 is further arranged in the armored cone 5, the cone bushing 3 is arranged on the inner side of the sealing ring 2, a threading hole is formed in the far end of the cone bushing 3, the diameter of the threading hole is equal to that of the cylindrical sleeve 22, and the cone bushing 3 is coaxial with the sealing ring 2. The cone bushing 3 is conical formed by a plurality of blade gaps, when in use, a cable enters the armored cone 4 through the guide sleeve 7, and the guide sleeve 7 enters the cone bushing 3 in the armored cone 4 together with the cable. After the cable passes through cone bush 3 and gets into sealing washer 2, a plurality of blades on the cone bush 3 will carry out the cladding to the cable like the jack catch, not only can avoid its slip to drop, simultaneously, if when exploding, the cone bush can also bear the impact that the inside explosion of cavity brought, can effectually avoid the flame that the inside explosion produced to wear out the cavity, great improvement the security that connects, the utility model discloses the effectual cold flow phenomenon of relying on constantly to extrude the cable to fix and bring among the prior art of having avoided.
