Abstract

A shell seat structure of the door closer of oil pressure which is produced into initial model part with aluminum alloy materials through the forming model; the assembly components are welded in the external surface of the shell seat, and the two-foot bodies provided with closing component perforation are arranged and fixed stably in the left and right sides of the shell seat respectively. Accordingly, the inner side of the shell seat is under the concaved space, thus the production cost can be reduced: a plurality of surface processes can be made in the appearance of the shell seat which is of artisticity.

Description

The outer shell base structure of oil pressure door closer

Technical field

The utility model relates to a kind of oil pressure door closer, particularly with the outer shell base structure of aluminum alloy material through molded and shaped oil pressure door closer.

Technical background

Generally be placed in the oil hydraulic type door closer between door leaf A and the doorframe B, as the installation site signal of Fig. 1 and the structure signal of Fig. 2, Fig. 3, its shell C cooperates moulding form to make with metal material (as aluminum alloy material) through die casting equipment, because in the middle of the process that die casting is made, can make the inside of this shell C produce countless little close pore C1, therefore must do again and polish modification step, just leakage phenomenon can not take place like this after filling in oil plant, otherwise have the bad situation of leakage of oil, so only increase polishes modification step promptly significantly increases the cost of making; Simultaneously, this shell C also makes at external surface very not smooth because be under the die casting making situation, again because this shell C has flint chemical analysis factor in the middle of die casting manufacturing process, causing doing anodization handles, therefore just only can or spray paint and handle, do baking vanish or spraying paint and also must can a glance just not find out that the exquisite inadequately situation of its external surface appears in the middle of handling simultaneously with dark coating japanning with baking vanish.

Have mirror the above, the applicant satisfies at above shortcoming part and improves seeking, and is to grind to create the utility model, and then proposes the application of patent.

Summary of the invention

The purpose of this utility model is to provide a kind of outer shell base structure of oil pressure door closer, and this outer shell base is molded with moulding form with aluminum alloy material, welding assembly is made.

Technical solutions of the utility model: a kind of outer shell base structure of oil pressure door closer is characterized in that having one and take out the aluminum alloy material outer shell base made type spare just by moulding form; Assembling fittings weldering knot is in the external surface of outer shell base; Bipod body with sealed perforation then welds knot respectively and is fixed on the beneath position, left and right both sides of outer shell base; Outer shell base inside has the accommodation space of a recessed sky.

The utility model beneficial effect: by said structure, the utility model can reach the reduction manufacturing cost, and can do various surfacings and have aesthetic property in the outer shell base appearance.And, this outer shell base can do anode handle or do baking vanish, surfacing such as spray paint, overcome the above-mentioned defective of traditional structure.

The specific embodiment

At first, please cooperate and consult Fig. 4, Fig. 5, Fig. 6, shown in Figure 7: the outer shell base structure of a kind of oil pressure door closer of the utility model, this door closer position is between door leaf A and doorframe B (as Fig. 1), and the outer shell base 1 of door closer is made with aluminum alloy material, it gives aluminum alloy materials and makes just that type spare (is Fig. 4 in the system of taking out through moulding form, Fig. 5), afterwards, the assembling fittings 11 weldering knots of having made typing are in the external surface of outer shell base 1, a left side that is fixed under the outer shell base 1 is tied in the then middle respectively weldering of bipod body 12 with sealed perforation 121, position, right both sides is (as Fig. 6, Fig. 7), outer shell base 1 can be for being installed on the precalculated position of door leaf A after the assembling interior fittings.Thus, owing to be the accommodation space of concaved hollow shape in outer shell base 1 inside, can reduce and give the whole manufacturing cost of reduction with material.Simultaneously, because this outer shell base 1 is made cause with the system of taking out, therefore can do various surfacings (as anode or baking vanish, surfacing such as spray paint) in outer shell base 1 appearance, and also no longer being confined to dark coating uses, thereby do not see that on the appearance sheet fine and closely woven hole is arranged, so have the aesthetic property of bright color and luster.

To sum up institute is old, and visible the utility model has practical effect really, meets the establishment condition of Patent Law.

Claims

1. the outer shell base structure of an oil pressure door closer is characterized in that, has one and takes out the aluminum alloy material outer shell base made type spare just by moulding form; Assembling fittings weldering knot is in the external surface of outer shell base; Bipod body with sealed perforation then welds knot respectively and is fixed on the beneath position, left and right both sides of outer shell base; Outer shell base inside has the accommodation space of a recessed sky.
