Abstract

The utility model discloses an improved vacuum tube tailstock which is mainly composed of a sheath (1) made of aluminum alloy section and a tail bracket (2), wherein the sheath (1) made of aluminum alloy section is tubular, one end of the sheath (1) is provided with an opening, and the other end is provided with a through hole after the other end is contracted; the tail bracket (2) tightly clings to the inner wall of the sheath and is supported by the contracted part of the sheath (1); a short tube (3) of the tail bracket (2) extends out of the sheath from the through hole of the sheath (1); a connecting component which is connected with a solar water heater support is arranged on the side wall of the sheath (1), and the connecting component and the sheath (1) are formed by the integral forming. The tail bracket is enwrapped by the sheath made of aluminum alloy section, so the utility model has the advantages of simple working procedure, and high rate of finished products; thereby, the production cost of the tailstock is lowered. Reinforcing ribs are arranged on the opening end and the through hole of the contracted part of the sheath, so the sheath strength is improved. When the tailstock is positioned, a user only needs to install the connecting component on the sidewall on the support, so the utility model is convenient to install.

Description

Improved vacuum tube tailstock

Technical field

The utility model relates to a kind of improved vacuum tube tailstock.

Background technology

The solar water heater vacuum-tube tailstock is made up of sleeve pipe, tail holder and connecting plate, and the afterbody of vacuum tube stretches in the sleeve pipe, and connecting plate is used for being connected with the water heater support, it is generally the integral molded plastic moulding, this moulding can not be resisted ultraviolet ray, easy aged deterioration, and service life is short; The employing aluminium diecasting is also arranged, the cost height; Perhaps adopt metallic plate through drawing and forming repeatedly,, cause yield rate low, improved production cost equally because the height that stretches is higher.

Summary of the invention

The utility model provide a kind of long service life, production cost low, make improved vacuum tube tailstock easy for installation.

The technical solution of the utility model is as follows: a kind of improved vacuum tube tailstock, it mainly is made up of aluminium alloy extrusions sheath and tail holder, the aluminium alloy extrusions sheath is a tubular, sheath one end opening, be provided with through hole behind the other end undergauge, the tail holder is close on the jacket inner wall diameter shrinkage part supporting by sheath, and the short tube of tail holder stretches out outside the sheath from the through hole of sheath, the sidewall of sheath is provided with the connector that is connected with rack of solar water heater, and connector and sheath are one-body molded.

In the utility model, connector has various ways, can be to enclose frame with the closure of sheath sidewall one, and enclosing the frame face relative with the sheath sidewall is the plane; Also can be to enclose frame, enclose the groove that the frame two sides bottom adjacent with the sheath sidewall is provided with symmetry with the closure of sheath sidewall one; Enclose between frame outer wall and the sheath sidewall and be provided with reinforcement; Or along the axial plate of sheath, plate is on the sidewall that wing is symmetricly set on sheath, and the surface that plate is carried sheath is provided with the block of projection.

The openend of sheath is provided with reinforcement; The diameter shrinkage part of sheath is plane, and perhaps projection is dome shape, annular conical surface shape; The sheath diameter shrinkage part forms reinforcement at the openings flange.

After adopting technique scheme, tailstock is wrapped in the tail holder by the aluminium alloy extrusions sheath, has prolonged the service life of tailstock greatly; The aluminium alloy extrusions that sheath and connector are formed in one, smooth in appearance is attractive in appearance, and production process is simple, and therefore the yield rate height has reduced the production cost of tailstock again; Sheath is provided with reinforcement at openend and openings, has improved the intensity of sheath., easy for installation during the tailstock location as long as the connector on the sheath sidewall is installed on the support.

The specific embodiment

Embodiment one: according to Fig. 1, shown in Figure 3, and the improved vacuum tube tailstock of the utility model, it mainly is made up of aluminium alloy extrusions sheath 1, plastics tail holder 2, and sheath 1 is a tubular, the sheath upper end open, openend is provided with reinforcement; The lower end is provided with central through hole after undergauge is handled, form reinforcement at the openings flange.It is plane that the diameter shrinkage part of sheath 1 can be, and also can be dome shape or annular conical surface shape to lower convexity; Tail holder 2 external diameters are identical with the internal diameter of sheath 1, and tail holder 2 is stretched into wherein from the upper end open of sheath 1, are close on the jacket inner wall diameter shrinkage part supporting by sheath 1, and the short tube 3 of tail holder 2 stretches out outside the sheath 1 from the through hole of sheath 1.The sidewall of sheath 1 is provided with connector, connector is used for being connected with the support of solar water heater, and connector is for to enclose frame 4 with the closure of sheath sidewall one, and enclosing frame 4 face relative with the sheath sidewall is the plane, be provided with reinforcement 8 between this plane and the sheath sidewall, can improve the intensity of enclosing frame 4.Enclose the aluminium alloy extrusions that frame 4 and sheath 1 are formed in one, easy to process, smooth in appearance is attractive in appearance.Enclose frame 4 and can be various ways such as rectangle frame, trapezoidal frame, perhaps with the jacket wall junction with arc-shaped transition etc.Frame 4 is corresponding with enclosing, be provided with open slot and to upper overturning on water heater support's plate, flange and reinforcement 8 corresponding positions are provided with groove, will enclose frame 4 and be inserted in the flange inboard, enclose frame 4 plane relative and be close to the back side of supporting plate, just can easily tailstock be installed on the support with the sheath sidewall.

Embodiment two: according to Fig. 2, shown in Figure 3, the structure of aluminium alloy type sheath 1, tail holder 2 is identical with embodiment one, different is connector, connector also is to enclose frame 4 with the closure of sheath sidewall one, enclosing the groove 5 that the frame 4 two sides bottoms adjacent with the sheath sidewall are provided with symmetry, enclose between frame outer wall and the sheath sidewall and be provided with reinforcement 8, can improve the intensity of enclosing frame 4.As long as be provided with open slot on the water heater support plate this moment, will enclose groove 5 on the frame and be stuck in from the position of open slot and just finish installation on the supporting plate.

Embodiment three: according to Fig. 4, shown in Figure 5, the structure of aluminium alloy type sheath 1, tail holder 2 is identical with embodiment one, different is connector, connector is along the axial plate 6 of sheath, plate 6 can be the outer rim of tabular protrusion at the sheath sidewall, also can be divided into two and be on the sidewall that wing is symmetricly set on sheath, the surface that plate 6 is carried sheath is provided with the block 7 of projection.Vertically be provided with two relative flange on the supporting plate correspondingly, and be provided with transverse groove, during installation plate 6 is inserted among the flange, block 7 stretches in the transverse groove and gets final product.
