Description

High-precision double-layer anti-explosion container

Technical Field

The utility model belongs to the technical field of double-deck antiknock container, concretely relates to double-deck antiknock container of high accuracy.

Background

Double-deck antiknock container or multilayer antiknock container all have explosion-proof cover generally, the urceolus, the three main parts of inner tube, because of its structure is comparatively complicated, constitute the apron of explosion-proof cover, the lid, barrel on buffer block and the urceolus, the connection lantern ring is general separately to be processed, after the processing is accomplished alone, the apron is with the mode of rethread welding, the lid, fix between barrel and the connection lantern ring, such processing mode is comparatively simple, but because electric welding warp, it is gapped between inner tube and the urceolus, easily rock when installing etc. and cause the concentricity between each part relatively poor, block easily when the lid is opened and close the operation, it is inconvenient during the use, in addition, in order to avoid the emergence of this kind of problem, can enlarge each size allowance of closed contact surface usually, lead to lid and barrel closure time gap grow, this can lead to the antiknock performance decline of antiknock container.

Disclosure of Invention

The utility model discloses to the relatively poor drawback that leads to the concentricity relatively poor among the prior art antiknock container installation accuracy, provide a double-deck antiknock container of high accuracy, this antiknock container installation accuracy is higher, and the concentricity is better to can promote holistic antiknock performance, the installation between the explosion-proof cover and the connection lantern ring is also very smooth and easy with the dismantlement, and the inner tube is also comparatively firm.

The invention aims to be realized by the following technical scheme: a high-precision double-layer anti-explosion container comprises an outer cylinder, a connecting lantern ring, an inner cylinder and an anti-explosion cover, wherein the connecting lantern ring is of a circular structure, the connecting lantern ring is fixedly arranged at the opening position of the outer cylinder, the inner cylinder is sleeved in the outer cylinder, a clamping ring sleeved outside the opening of the inner cylinder is arranged between the opening outer side of the inner cylinder and the connecting lantern ring, and the outer wall of the clamping ring is connected with the inner wall of the connecting lantern ring; explosion-proof lid is including apron and lid, the fixed cover that is equipped with of terminal surface is established outside the adapter sleeve ring, apron intermediate position open have with the coaxial screw that sets up of spacing ring, the lid includes spliced pole and the shirt rim of coaxial setting, and the spliced pole is fixed to be set up at skirt up end and spliced pole and shirt rim formula structure as an organic whole, and the shirt rim is salient for the spliced pole side, the spliced pole stretches into in the screw hole and with the screw spiro union, the shirt rim is terminal surface laminating under the side of spliced pole and the apron, the shirt rim stretches into be threaded connection or joint between adapter sleeve intra-annular and shirt rim and the adapter sleeve ring. Among the above-mentioned scheme, divide into apron and lid with explosion-proof lid and divide into two parts, can separately process, separately process and to reduce the processing degree of difficulty, and the lid includes spliced pole and the shirt rim of coaxial setting, so apron and lid can both adopt lathe processing, and then can guarantee the concentricity of spliced pole and shirt rim on the lid, further can also guarantee the concentricity between apron and the lid.

The concentricity of the explosion-proof cover, the connecting lantern ring and the inner cylinder is ensured, the mounting precision is improved, the clearance between the parts is reduced, and the anti-explosion performance of the container is improved while the mounting and the dismounting of the explosion-proof cover become very smooth. When the explosive in the antiknock container explodes, the limiting ring arranged on the cover plate can limit the connecting sleeve ring, so that the upper end of the connecting sleeve ring is prevented from outwards cracking, and the antiknock performance is improved. The rand that sets up not only can the toggle inner tube opening outside, prevents that the inner tube open end from tearing because of the explosion, promotes antiknock performance, can also spacing to the inner tube, prevents that the inner tube from rocking in the urceolus. The rand can directly fix on the connection lantern ring, also can with the split type design of connection lantern ring, the cover is established in the adapter sleeve intra-annular. The lower end of the skirt edge extends into the opening of the inner barrel, and the outer wall of the skirt edge is attached to the inner wall of the inner barrel. Because of the concentricity of above-mentioned each part is higher, so can set up like this, the shirt rim that sets up like this with the rand cooperation can be better carry on spacingly to the inner tube, prevents that the inner tube from rocking in the urceolus, simultaneously, also can reduce the gap between shirt rim and the inner tube, and then promote antiknock container's antiknock performance.

Preferably, the collar is fixedly arranged on the inner side of the connection sleeve ring and is coaxially arranged with the connection sleeve ring.

Preferably, the clamping ring is composed of a plurality of arc blocks distributed in a circumferential array around the central line of the connecting sleeve ring, the inner diameter of each arc block is equal to the outer diameter of the inner cylinder, and the arc blocks and the connecting sleeve ring are of an integrated structure. The arc piece that sets up like this can be with the adapter sleeve ring together through lathe processing earlier, and rethread line cutting machine tool processes out together, and the arc piece and the adapter sleeve ring of a body structure, its concentricity is better, is favorable to promoting the installation accuracy, and the structure is more firm.

Preferably, the skirt edge and the connecting sleeve ring are clamped, eight clamping blocks which are distributed in a circumferential array mode around the central line of the skirt edge are fixedly arranged on the outer side face of the skirt edge, intervals are reserved between the clamping blocks and the lower end face of the cover plate, eight clamping teeth which are distributed in a circumferential array mode around the central line of the connecting sleeve ring are fixedly arranged at the upper end of the inner wall of the connecting sleeve ring, and the thickness of each clamping tooth is not larger than the distance between each clamping block and the cover plate. The clamping blocks and the clamping teeth are arranged in a large number, so that the explosion-proof cover can be opened and closed only by rotating by a small angle, and the explosion-proof cover is easier to operate.

Preferably, the number of the arc blocks is eight, the eight arc blocks correspond to the eight clamping teeth one by one, the arc blocks are located right below the corresponding clamping teeth, and the length of the arc blocks is equal to that of the clamping teeth. When the connecting lantern ring is machined by a lathe, two coaxial circular rings can be machined on the inner side of the connecting lantern ring by the lathe, and the latch and the circular arc block are machined by the linear cutting machine together, so that the machining is more convenient.

Preferably, the skirt is in threaded connection with the connecting sleeve ring.
