Description

Fast-assembling head

Technical Field

The utility model relates to the technical field of end sockets, in particular to a quick-mounting end socket.

Background

The end cap is an element for sealing the end of the container to isolate the internal and external media, and is also called an end cap. The closure head of a cylindrical container is generally a swivel housing. The shape of the surface of the end socket can be divided into convex, conical, flat and combined shapes. The convex end socket refers to an end socket with a convex outer surface shape, such as a hemispherical, oval, dished and edgeless spherical end socket.

The sealing connection mode between current head and the container is mostly welded seal, and welded seal's mode complex operation, work load are big, and when the material received expend with heat and contract with cold deformation, the fracture very easily takes place in welding seam department to finally influence the leakproofness of container, and welded mode can't carry out the dismouting to the head. The present invention was made in light of the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a quick-assembly seal head which is good in sealing performance and can be disassembled and assembled.

The technical purpose of the utility model is realized by the following technical scheme: the utility model provides a fast-assembling head, includes the head body, the head body includes the casing portion of sphere and connects the ring shape connecting portion at casing portion border, the border of connecting portion is equipped with the breach, the breach encircles around the centre of a circle in connecting portion and is provided with a plurality ofly, the internal perisporium of connecting portion is equipped with the sealing washer, every equal fixed engaging lug that is provided with flexibility in the breach, be formed with the deformation clearance that supplies the engaging lug along the radial deformation of connecting portion between engaging lug and the breach, every the medial surface of engaging lug all is equipped with the locating piece that is used for imbedding the container.

Through adopting above-mentioned technical scheme, the setting in deformation clearance supplies the engaging lug better deformation when the atress, makes the deformation operation of engaging lug more convenient. Before installation or before leaving the factory, the connecting lug is driven by equipment to deform outwards, so that the positioning block cannot interfere with the container in the process of loading the seal head into the container, and the smooth operation of an assembly process is ensured. After the seal head reaches the specified position of the container, the connecting lug is driven to deform inwards through equipment, the deformed connecting lug drives the positioning block to be embedded into the container, so that the seal head and the container are assembled and fixed, and the existence of the sealing ring ensures the sealing property between the seal head and the container, so that a better sealing effect is achieved. When the seal head and the container are to be detached, the connection lug is driven by the equipment to deform outwards so as to realize convenient separation of the seal head.

Further setting the following steps: the periphery wall of connecting portion is equipped with the positioning ring groove, positioning ring inslot is equipped with solid fixed ring.

Through adopting above-mentioned technical scheme, the setting of holding ring groove is spacing to the solid fixed ring realization of installation, ensures the installation stability of holding ring, forms spacing assembly strength who further promotes between head and the container through the holding ring to the engaging lug, prevents that the engaging lug from outwards deforming.

Further setting the following steps: the number of the deformation gaps formed between each notch and the corresponding connecting lug is two, the two deformation gaps are respectively positioned on two sides of the connecting lug, and the positioning block is conical.

Through adopting above-mentioned technical scheme, this kind of setting up in deformation clearance provides better deformation space for the engaging lug, makes the engaging lug can be better when the atress deform, and conical locating piece can be faster imbeds the container, makes the location operation more convenient, laborsaving.

Further setting the following steps: the opening of the interior perisporium of sealing washer outwards is the flaring gradually along the connecting portion and sets up and form an inclined guide face, the sealing washer is equipped with the sealing portion that offsets tightly with the container terminal surface towards the terminal surface of casing portion.

Through adopting above-mentioned technical scheme, the setting of slope guide face plays the guide effect to the container that gets into the sealing washer, prevents that container and head from causing the displacement of sealing washer and influencing the leakproofness between the two at the in-process of assembly. The sealing ring is abutted against the outer peripheral wall of the container to form a seal, and the sealing part is abutted against the end face of the container to form two seals, so that a better sealing effect is achieved.

Further setting the following steps: the internal perisporium of connecting portion is equipped with the spacing ring that offsets in a sealing portion back to a sealing washer terminal surface, be connected with the strengthening rib between spacing ring and the casing portion, the strengthening rib encircles around the centre of a circle in the spacing ring and is provided with a plurality ofly.

Through adopting above-mentioned technical scheme, the setting of spacing ring supports the sealing, reduces the displacement deformation of sealing when the atress to realize the inseparabler seal between sealing and the container terminal surface, reach better sealed effect. The setting of strengthening rib promotes the structural strength of spacing ring, realizes better bearing force.

Further setting the following steps: the outer wall of casing portion is equipped with two connecting blocks, two all be connected with the lug on the connecting block.

Through adopting above-mentioned technical scheme, the area of contact between setting up increase lug and the casing portion of connecting block prevents to cause the local deformation of casing portion in handling, and the setting up of lug provides the tie point for the transport, makes the transport of head more convenient.

In conclusion, the utility model has the following beneficial effects: the utility model has good sealing performance, long service life and high strength, can realize disassembly and assembly and is mainly applied to low-pressure working conditions.
