Description

Combined anti-explosion container cover body structure

Technical Field

The utility model belongs to the technical field of antiknock container, concretely relates to modular antiknock container lid structure.

Background

The anti-explosion container is special equipment for transporting and storing dangerous goods such as detonators, explosives and the like, and has strong anti-explosion performance and shielding performance. The existing anti-explosion container generally comprises an outer cylinder, an inner cylinder and a cover body structure. The cover body structure generally adopts an integrated molding structure, and in order to ensure the shielding performance of the container, a conductive rubber mounting groove which needs to be matched with the cylinder body is required to be arranged on the cover body of the container. The outer edge of the cover body is provided with a clamping ring to improve the anti-explosion performance of the outlet of the anti-explosion container. If the cover body adopts an integrally formed production mode, steel with larger diameter and larger volume is needed to be processed, the material waste is large, the cost is high, structures such as a cover plate, a clamping ring and a connecting ring need to be processed, structures such as a clamping tooth or an external thread need to be processed outside the connecting ring, especially when a lathe is used for processing the joint of a connecting part and the cover plate, the clamping ring is positioned at the outer end of the cover plate and protrudes downwards relative to the cover plate, the telescopic space of a turning tool is blocked, the lathe can only slowly turn once to avoid the situation that the tool hits the workpiece and damages the workpiece or equipment, the processing difficulty is very high, and the equipment is easy to damage. The processed cover body is heavy in weight and is not easy to open and close.

Disclosure of Invention

The utility model discloses it is extravagant big to the lid structure material of antiknock container among the prior art, and with high costs, and difficult processing, drawback such as processing equipment loss are big, provide a modular antiknock container lid structure, this lid structure divide into apron and explosion-proof cover two parts, and processing is got up more simply, and the material is more saved, and the cost is lower, and the processing equipment loss is little, light in weight, and assembles through the mode of spiro union between apron and the explosion-proof cover, and is very simple and convenient.

The invention aims to be realized by the following technical scheme: a combined type anti-explosion container cover body structure comprises a cover plate and an anti-explosion cover, wherein the cover plate and the anti-explosion cover are of an integrally formed structure, a screw hole is formed in the middle of the cover plate, and the edge of the cover plate is fixedly connected with a clamping ring of a downward protruding circular structure; the anti-explosion cover comprises a cover body and a connecting column, wherein the outer side surface of the cover body is provided with a connecting part which is used for being detachably and fixedly connected with a barrel of an anti-explosion container, the connecting column is fixedly arranged at the middle position of the upper end of the cover body, the diameter of the connecting column is smaller than the outer diameter of the cover body, a step-shaped structure is formed between the connecting column and the cover body, an external thread is arranged on the outer surface of the connecting column, the connecting column is screwed with the screw hole through the external thread, the upper end surface of the cover body is attached to the lower end surface of the cover plate, limiting grooves which correspond to each other are respectively arranged on the side wall position of the screw hole on the cover plate and the outer side surface of.

In the above scheme, apron and explosion-proof cover are independent part respectively, adopt simple lathe work just can realize processing production basically, process more simply, can reduce the processing degree of difficulty, simultaneously, with apron and explosion-proof cover processing alone respectively, can adopt the material that the volume is less relatively to produce, the material that cuts off is less, is favorable to save material, reduction in production cost. The connecting column and the cover body are designed into the stepped structure, so that when the explosion-proof cover is in threaded connection with the cover plate, the explosion-proof cover and the cover plate only need to rotate relatively until the upper end face of the cover body is attached to the lower end face of the cover plate, the explosion-proof cover and the cover plate can be ensured to rotate in place, and the situation that the explosion-proof cover is not screwed is avoided. And the setting of spacer pin can avoid taking place relative rotation between explosion-proof cover after screwing and the apron, avoids not hard up the emergence of phenomenon.

Preferably, the screw hole penetrates through the upper end face and the lower end face of the cover plate, the limiting groove in the cover plate is communicated with the upper end face of the cover plate, and the limiting groove in the connecting column is communicated with the upper end face of the connecting column. The limiting hole inner side wall is provided with an internal thread, and the limiting pin is a screw. In actual production, the cover plate and the explosion-proof cover are screwed tightly, a hole is processed at the joint of the connecting column and the cover plate by using a drilling machine, the limiting pin is directly inserted, or a self-tapping screw is used for directly driving a screw, a limiting groove does not need to be processed independently, and then the limiting groove is spliced to form the limiting hole, so that the production is more convenient.

Preferably, the cover plate is made of aluminum alloy, and the explosion-proof cover is made of manganese steel. The cover plate and the explosion-proof cover are independent parts, so that the cover plate and the explosion-proof cover can be produced by adopting different materials, all parts of the existing cover body structure are generally made of manganese steel, although the cover body structure has good anti-explosion performance, the whole weight of the cover body structure is larger, the cover body structure is inconvenient to carry and open and close,

what actually plays the blast proof effect, receives the shock wave in the antiknock container is the blast proof lid, so the blast proof lid must use the manganese steel that intensity is higher to make, and the impact force that the apron bore is extremely limited, so can adopt the aluminum alloy to make, set up like this and adopt the manganese steel to make lighter for whole, can alleviate the whole weight of lid structure.

Preferably, the connecting portion is a latch fixedly provided on an outer side surface of the lid body or an external thread provided on an outer side surface of the lid body. Can realize through this connecting portion the utility model discloses can dismantle fixed connection with the barrel part of antiknock container.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses can reduce the processing degree of difficulty, save material to can reduction in production cost, can also make the apron adopt lighter aluminum alloy to produce simultaneously, thereby can alleviate whole weight.
