Description

Hollow projectile cartridge spring support
Technical field
The utility model relates to a kind of spring(-supported) mount parts of thing to sit on, belongs to furniture technical field.
Background technology
Existing thing to sit on class furniture is as sofa etc., complex structure, and base adopts enclosed construction, consumer is difficult to see its inner materials in the situation that not destroying thing to sit on structure, this adulterates, uses inferior materials and turns out substandard goods in technique and manufactured chance to some illegal manufacturers on materials, and product quality can not be guaranteed.Chinese patent that the inventor obtained in the past " metal spring bracket and adopt the sofa base of this bracket ", the patent No. are: 201120359609.X, simplify the structure of thing to sit on base, and change the multilayered structure of conventional base.But said structure is Shortcomings part also: what it adopted is very thin metal edge frame, can only be screwed on wooden frame or base, cannot install and use separately; Spring(-supported) mount mounting groove is left in the top of base, when spring(-supported) mount need to be movably arranged on base, such as inlaying or when hinged, must fix in its underpart wooden frame, cannot match with the degree of depth of spring(-supported) mount mounting groove otherwise metal edge frame is very thin, cannot install, and, the manufacture craft of above-mentioned metal edge frame is comparatively complicated, needs welding repeatedly.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of hollow projectile cartridge spring support, and very thin metal framework before having changed, can independently install and use spring(-supported) mount, does not need to fix in addition wooden frame again, and processing technology simple and fast.
The utility model is achieved by the following technical solution: a kind of hollow projectile cartridge spring support, it comprises hollow metal framework, hollow metal framework is to enclose by the hollow pipe or the section bar that include inner side riser " returning " glyph framework forming, above hollow metal framework, be plane with medial surface below, the medial surface of hollow metal framework is fixed with two spring fitting bars that are oppositely arranged, on spring fitting bar, there is the extension spring support of level, hang the upper plane of spring support lower than hollow metal framework, between two spring fitting bars, level is fixed with the flat S-shaped spring of many rows.
Described hollow pipe is square tube or flat tube; Described section bar is opening grooved section outwardly.
Described spring fitting strip adoption angle bar or angle steel, a limit of angle bar or angle steel is fixed on the medial surface of hollow metal framework, and another limit of angle bar or angle steel is as the extension spring support of level.
On the extension spring support of described spring fitting bar, be manufactured with through hole, the two ends downward bending of described S-shaped spring inserts in through hole.
On the extension spring support of described spring fitting bar, stamp out arc-shaped protrusions, the below of arc-shaped protrusions and two ends form cross through hole, and the both ends horizontal of described S-shaped spring is inserted in arc-shaped protrusions.
The beneficial effects of the utility model are:
1, the utility model is simple in structure, comfortable, durable, changed before very thin metal framework, spring(-supported) mount can independently be installed and used, well mate with base, do not need to fix in addition again wooden frame, more resistance to draw durable.
2, the utility model hollow pipe adopts square tube or flat tube; Or adopt opening grooved section outwardly, processing technology simple and fast, can adopt bending machine rapid shaping, has saved welding procedure, has saved working time.
3, the utility model spring fitting strip adoption angle bar or angle steel, easy for installation, do not need again metal frame to be suppressed to bending; On the extension spring support of spring fitting bar, can stamp out arc-shaped protrusions, the below of arc-shaped protrusions and two ends form cross through hole, and the both ends horizontal of described S-shaped spring is inserted in arc-shaped protrusions.Do not need again the two ends of S-shaped spring to be carried out the processing of downward bending.

In figure, 1, hollow metal framework, 1-1, inner side riser, 2, S-shaped spring, 3, spring fitting bar, 3-1, through hole, 3-2, arc-shaped protrusions, 4, sofa base, 5, set square.
Detailed description of the invention
A kind of hollow projectile cartridge spring support as shown in Figure 1, Figure 2, Figure 3 shows, it comprises hollow metal framework 1, hollow metal framework 1 is to enclose by the hollow pipe or the section bar that include inner side riser 1-1 " returning " glyph framework forming, and four jiaos of hollow metal framework 1 can be right angle, can be also fillet.Above hollow metal framework 1, be plane with medial surface below, the medial surface of hollow metal framework 1 is fixed with two spring fitting bars 3 that are oppositely arranged, on spring fitting bar 3, there is the extension spring support of level, hang the upper plane of spring support lower than hollow metal framework 1, between two spring fitting bars 3, level is fixed with the flat S-shaped spring 2 of many rows.
If employing hollow pipe, can be square tube or flat tube, processing technology simple and fast, can adopt bending machine rapid shaping, has saved welding procedure, has saved working time.If employing section bar, preferably opening grooved section outwardly, can ensure hollow metal framework 1 above, be plane with medial surface below.Medial surface i.e. inner side riser 1-1, and it has ensured the height of hollow metal framework 1.
Described spring fitting bar 3 adopts angle bar or angle steel, and a limit of angle bar or angle steel is by screw or be weldingly fixed on the medial surface of hollow metal framework 1, and another limit of angle bar or angle steel is as the extension spring support of level.
As shown in Figure 3, on the extension spring support of described spring fitting bar 3, be manufactured with through hole 3-1, the two ends downward bending of described S-shaped spring 2 inserts in through hole 3-1.
As shown in Figure 4, Figure 5, on the extension spring support of described spring fitting bar 3, stamp out arc-shaped protrusions 3-2, the below of arc-shaped protrusions 3-2 and two ends form cross through hole, and the both ends horizontal of described S-shaped spring 2 is inserted in arc-shaped protrusions 3-2.Do not need again the two ends of S-shaped spring to be carried out the processing of downward bending.
When installation, example as shown in Figure 6, Figure 7, base 4 is hollow base, spring(-supported) mount mounting groove is left in the top of base 4, the Corner Strapped of mounting groove has set square 5, the height of hollow metal framework 1 and spring(-supported) mount mounting groove match, the utility model hollow projectile cartridge spring support is embedded in spring(-supported) mount mounting groove, quadrupod is located on set square 5, hollow projectile cartridge spring support mates completely with base 4, the upper plane of hollow metal framework 1 and base 4 flushes above, need to below spring(-supported) mount, not fix in addition wooden frame, more resistance to draw durable.
