Description
Technical field
The present invention relates to a kind of positioner, especially a kind of dustproof positioning door spring.
Background technology
For the door that prevents to open is closed unintentionally by wind or other external force, the metope of base angle correspondence was provided with the magnet door-inhale and realizes the location when people generally opened with door at the base angle of door, this locate mode, though can prevent that also door from being closed unintentionally, but its anchor point has only one, can only be the complete opening state, other states then can't be realized.
It also is that dust enters one of the main channel in room that door bottom crack can't seal, woods Qinghai and Ding Guozhen have applied for that to Patent Office of the People's Republic of China name is called the utility application of " door bottom crack automatic sealing device " on July 13rd, 1999, and grant patent, the patent No. is 99224434.X, and notice of authorization number is CN2380671Y.Though this patent can realize sealing to door bottom crack when door is closed, play certain dustproof effect, complex structure, and the location that can't realize opposite house relatively.
Can realize the device of the positioning dust-proof of door at present simultaneously, not appear in the newspapers as yet.
Summary of the invention
The objective of the invention is to: can't realize that at present product door can both realize the location under various openings, also not have simultaneously to take into account the location and the dustproof device of door, a kind of dustproof positioning door spring is provided.
The object of the present invention is achieved like this: a kind of dustproof positioning door spring, it is characterized in that: comprise that a cross section equates with the bottom rail of door for " ∏ " shape length and the two side of notch under bead the section bar of interior flanging is all arranged, is furnished with the identical bar shaped location press strip of length in the notch of section bar, the both sides at press strip top, bar shaped location are provided with the edge of protrusion, at least be provided with two spring bases in the notch of section bar, spring on the spring base is pressed on the end face of location press strip, the bottom of location press strip is provided with the groove of axial perforation, by this groove inlay one with locate the identical dust seal rubber strip of press strip length.
For the press strip two ends, bar shaped location that dispose in the notch that prevents section bar upwarp, in the notch of section bar two ends adjacent end, should be provided with spring base at least, the spring on the spring base is pressed on the end face of location press strip.
Above-mentioned spring base can be realized like this: preset aperture in the cross section for the section bar top of " ∏ " shape, bolt inserts aperture and fixes by nut, and the screw rod and the hold-down nut that insert aperture form spring base.
In the groove that makes the bottom that is embedded in the location press strip that the dust seal rubber strip can be more firm, the groove that the bottom of location press strip is provided with axial perforation is a dovetail groove.
The invention has the advantages that: compact conformation, can guarantee in the use that door can both realize the location under various openings, simultaneously the end of opposite house seam is realized sealing when door is closed, and plays certain dustproof effect.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram that the present invention relates to;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a kind of embodiment that spring base is set in section bar that the present invention relates to.
Among the figure: 1, section bar, 2, spring base, 3, the location press strip, 4, the dust seal rubber strip, 5, notch, 6, the edge that protrudes, 7, aperture, 8, bolt, 9, nut, 10, spring, 11, groove
The specific embodiment
Accompanying drawing discloses the concrete structure that a kind of embodiment of the present invention relates to without limitation, and the invention will be further described below in conjunction with accompanying drawing.
As seen from Figure 1, invention comprises the section bar 1 that a length equates with the bottom rail of door, is furnished with the identical bar shaped of length location press strip 3 in the notch of section bar 1, the bottom of locating press strip 3 inlay one with locate the identical dust seal rubber strip 4 of press strip 3 length.
As seen from Figure 2, all there is interior flanging in the cross section of section bar 1 for bead under the two side of " ∏ " shape and notch 5, the location press strip 3 of being furnished with the edge 6 that the both sides, top are provided with protrusion in the notch 5 of section bar 1, at least be provided with two spring bases 2 in the notch 5 of section bar 1, spring 10 on the spring base 2 is pressed on the end face of location press strip 3, the bottom of location press strip 3 is provided with the groove 11 of axial perforation, by this groove 11 inlay one with locate the identical dust seal rubber strip 4 of press strip length.
In Fig. 1, embodiment shown in Figure 2, for location press strip 3 two ends of configuration in the notch 5 that prevents section bar 1 upwarp, in the notch 5 of section bar 1 two ends adjacent end, should be provided with spring base 2 at least, the spring on the spring base 2 is pressed on the end face of location press strip 3; In the groove 11 that makes the bottom that is embedded in location press strip 3 that dust seal rubber strip 5 can be more firm, the groove 11 that the bottom of location press strip 3 is provided with axial perforation is dovetail groove, and inlays dust seal rubber strip 4 by this dovetail groove.
Can realize by mode shown in Figure 3 for the spring base 2 that is provided with in the section bar 1 of " ∏ " shape in the cross section: preset aperture 7 for section bar 1 top of " ∏ " shape in the cross section, bolt 8 inserts aperture 7 and fixing by nut 9, and the screw rod and the hold-down nut that insert aperture form spring base 2.In the present embodiment, bolt 8 is a countersunk bolt.
Before the use, as long as offer a through slot parallel with the shop front at the bottom of door, this groove and cross section are that the section bar of " ∏ " shape is complementary, and the through slot at the bottom of the present invention is placed is installed on door on the doorframe again.During actual the use, under the effect of spring 10, be positioned all the time press strip 3 and dust seal rubber strip 4 of the slit between the door end and the ground tamps, and seam is realized sealing at the end of opposite house when door is closed, and has tangible dustproof effect; When door is opened, no matter be in which kind of opening angle, the frictional force between dust seal rubber strip 4 and the ground can both realize the location by opposite house, and especially under the effect of spring 10, the frictional force between dust seal rubber strip 4 and the ground is bigger, and locating effect is better.
