Description

Door check

The utility model relates to a kind of door check.

As shown in Figure 1 and Figure 2, general door check mainly be by: holder 2, gear rod member 3, fixed cover 4, connection rod set 5, tooth bar seat 6, spring 7 and fixed cap 8 constitute.The two ends of holder 2 are provided with locating hole 21, can not be fixed on the wall by screw (drawing), and the inside 22 of holder 2 is set as hollow vertically, and its outside central authorities establish one and are nested with hole 23 and communicate with its hollow inside 22; Gear rod member 3 covers are through set being nested with in the hole 23 of holder 2 outside central position; Fixed cover 4 is fixed on being nested with in the hole 23 of holder 2 with gear rod member 3; Connection rod set 5 one ends are articulated on gear rod member 3 ends, and the other end then articulates with doorframe and window frame (not drawing); Tooth bar seat 6 is enclosed within the hollow inside 22 of holder 2, and the one side is provided with gear 31 engaged transmission on tooth bar 61 and the gear rod member 3; Spring 7 is can be for tooth bar seat 6 reciprocating and be arranged in the hollow inside 22 of holder 2; Fixed cap 8 be fixed on tooth bar seat 6 and spring 7 in the holder 2 hollow inside 22 and locking at holder 2 two ends.

After the said structure combination, when desiring door and window, the strength of whole door and window, just can be through the interlock of connection rod set 5, driven gear rod member 3 rotation, and make set window bar 61 engaged transmission on gear 31 and the tooth bar seat of putting in holder 2 hollow inside 22 6 on it, and make whole tooth bar seat 6 overcome putting equally elastic force at inner 22 medi-springs 7 of holder 2 hollows, reach and make tooth bar seat 6, successfully with the effect of opening of doors and windows at holder 2 interior slips.When opening behind the door, user one lets go and when leaving doorframe and window frame, just can change elastic force by the spring 7 of fixed cover 2 hollow inside 22, and promote tooth bar seat 6 in the opposite direction, slide in fixed cover 2 hollows inner 22, and with season the tooth bar on it rotate, gear 31 on the driven gear rod member 3 also rotates in the opposite direction, and 5 actions of drivening rod group, make connection rod set 5 drive whole doorframe and window frame at last, reach the effect that whole doorframe and window frame is closed automatically.

As shown in Figure 2, in the structure of above-mentioned door check holder, its whole holder 2 mainly is to be formed by the die casting of zinc products one, and is made into the structure that is hollow inside 22 vertically.The major defect of this structure is: be material with the metal all because of its integral body 1,, increase its material cost virtually; 2, be to be made into integration because of its structure with die casting, particularly it is hollow inside, must make whole tooth bar seat 6 and spring 7 be nested with the location, more must make whole tooth bar seat 6 be able to empty therein inside and do slippage smoothly, for make its slippage more smoothly must with whole hollow inside more in addition in addition car system be processed into smooth surface, inside, increase whole cost of processing virtually greatly; 3, be that die casting forms because of whole holder, this hollow inside often can form the sand hole of various different sizes unavoidably, when formed sand hole is excessive, even its whole hollow inside is again through car system, the aperture of its hollow inside will be above desired tolerance situation, form substandard product, and have much room for improvement.

The purpose of this utility model provides a kind of capable again door check of processing, reducing error, reasonable in design in hollow inside that can reduce cost, avoid holder greatly.

For achieving the above object, the technical solution of the utility model is: a kind of door check mainly is made of: holder, gear rod member, fixed cover, connection rod set, tooth bar seat, spring and fixed cap; The two ends of holder are provided with locating hole, and its inside is set as hollow vertically, and its outside central authorities establish one and are nested with its hollow inside of Kong Bingyu and communicate; Gear rod member cover is through set being nested with in the hole of holder outside central position; Fixed cover is fixed on being nested with in the hole of holder with the gear rod member; One end of connection rod set is articulated in gear rod member end, and the other end and doorframe and window frame articulate; The tooth bar cover for seat is in holder hollow inside, and the gear on the rack and pinion rod member that the one side is provided with is made engaged transmission; The spring that is positioned at holder hollow inside can make the tooth bar seat reciprocating; Tooth bar seat and spring that fixed cap will be arranged in holder hollow inside lock respectively at the holder two ends; It is characterized in that:

Described holder inside vertically, the hollow part that is nested with for tooth bar seat and spring is one to have the hollow metal body of preferable radian, and with the peripheral plastic cement one of holder ejection formation, and make a complete holder.

Because the utility model adopts above design scheme, so have the following advantages: 1, directly make with the body cooperation because of the hollow inside of whole holder, the tolerance dimension that provides the tooth bar seat to cooperate with spring, must again processing not gone (and after the processing again in the hollow inside of holder, cause because of sand hole, also often still have defective products to produce), and reach the effect that requires of institute's palpus easily.2, in the manufacture process of whole holder, its inside is the position of hollow vertically, for tooth bar seat and spring portion's reciprocating motion within it, reaches effect more smoothly with preferable radian.3, because of holder plastic cement one peripheral ejection formation with it, this yield that contracts that in natural cooling process, is produced of its plastic cement, the caliber size of the whole holder hollow of unlikely influence inside effectively cooperates and reach the tooth bar seat and the spring that can effectively keep in it.4, because of whole holder plastic cement one ejection formation, avoid secondary operations, so reduce cost greatly.

Further specify below in conjunction with the drawings and specific embodiments.

As Fig. 1, Fig. 3, shown in Figure 4, door check of the present utility model mainly is made of: holder 2, gear rod member 3, fixed cover 4, connection rod set 5, tooth bar seat 6, spring 7 and fixed cap 8.The two ends of holder 2 are provided with locating hole 21, can not be fixed on the wall by screw (drawing), and the inside 22 of holder 2 is set as hollow vertically, and its outside central authorities establish one and are nested with hole 23 and communicate with its hollow inside 22; Gear rod member 3 overlaps through holder 2 outsides, set being nested with in the hole 23 of middle position; Fixed cover 4 is fixed on being nested with in the hole 23 of holder 2 with gear rod member 3; Connection rod set 5 one ends are articulated on gear rod member 3 ends, and the other end then articulates with doorframe and window frame (not drawing); Tooth bar seat 6 is enclosed within the hollow inside 22 of holder 2, and the one side is provided with gear 31 engaged transmission on tooth bar 61 and the gear rod member 3; Spring 7 can provide tooth bar seat 6 reciprocating and be arranged in the hollow inside 22 of holder 2; Fixed cap 8 be fixed on tooth bar seat 6 and spring 7 in the holder 2 hollow inside 22 and locking at holder 2 two ends.And main being characterised in that of the present utility model: when making holder 2 at first, the hollow part 22 that its inside provides tooth bar seat 6 and spring 7 to be nested with vertically, change with a hollow metal body 22 ' directly cooperate holder 2 peripheries 24 with plastic cement one ejection formation, and make a complete holder 2, and make a preferable radian and make tooth bar seat 6 and spring 7 routing motion better, can reduce cost greatly simultaneously.

The above only is preferred embodiment of the present utility model, and any equivalence based on the technical program changes, and all belongs in the protection domain of the present utility model.
