Abstract

The utility model relates to a household product for families. Everyone knows that the gap between a door and a door frame is changed follow the changes of temperature and humidity is obviously enlarged in winter due to the reason of heat expansion and cold contraction, and the door is hard to close tightly so that the heat in the room is lost. The beautiful appearance is affected by adopting a draw spring method, and a husk can be nailed in winter, but the husk can be pull out in summer, therefore, the way is inconvenient. The household product for families can adjust the tightness degrees of the door according to the need of the hosts so that the users are provided with convenience. The household product for families is composed of a contact card, a wood screw, a roller latch shell, a spring, a casing seat, an adjustable screw bolt, a steel ball, a casing, etc. The friction force between the contact card and the roller latch can be increased or reduced by the screw in or screw out of the adjustable screw bolt so that the goal of the tightness degree adjustment of the door can be achieved.

Description

Adjusting device for movement of door wing

The utility model is a kind of device that can be used to the elasticity of adjustment doors.

Because the coefficient of expansion of wood materials is bigger, therefore can't produce a kind of door that is suitable for elasticity in four seasons of spring, summer, autumn and winter at present.Actual conditions are: in order to take into account four seasons, the door of making summer, rainy season its elasticity still can, then obviously fluff to winter, make troubles for people's life, (kitchen and bedroom are not together-be not self-contained flat) is all the more so especially in the rural area.People can not be on going out door lock, and again the thing in the hand (as meal of holding etc.) is put down and unblanks when entering house.Common way has two kinds now: the one, and, lagen leather strap (or extension spring); The 2nd,, follow closely piece skin etc. at the end face of door (or doorframe), the former influences attractive in appearance, and the latter one must take off it to summer, real genus inconvenience.

The purpose of this utility model provides a kind of adjusting device, and it can be according to the degree of tightness of actual conditions free adjustment door, and does not affect the appearance.

The purpose of this utility model is achieved in that and is installed on the doorframe bumping card, adjusting device (bump pearl in it and regulate bolt) is installed on the door, bump pearl and bump frictional force effect between card by the precession of regulating bolt or back-out being played increase or reduce, thereby reach the tight or loose purpose of adjustment doors.

Owing to adopt said method, can be under situation about not affecting the appearance, the degree of tightness of adjustment doors easily, and simple in structure.

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 bumps card, and Fig. 2 bumps pearl, and Fig. 3 regulates bolt, and Fig. 4 is an outer casing seat, and Fig. 5 is an overcoat, and Fig. 6 is an assembling drawing.

In Fig. 6, bumping card (1) is fixed on the doorframe, wood screw (2) (having seven) fixedly bumps card (1) and outer casing seat (5) respectively, bumping pearl (3) has compression spring (4) and reduced faucal and sealing steel ball (7) within it to be made up of the metal shell (3) of end sealing in it, stage clip (4) assurance steel ball (7) with bump card (1) satisfied frictional force arranged when contacting; Bump pearl (3) and can in overcoat (8), do reciprocal freely-movable, and overcoat (8) is fixed on the door by outer casing seat (5), regulate that bolt (6) utilizes overcoat (8) but the screw thread precession (eject and bump pearl (3)) at rear portion or screw out (make bump pearl (3) be retracted into), bump pearl (3) and fix and the anterior jackscrew of installing (being the screw of jackscrew as the M3 among Fig. 5) of overcoat (8) can adjusted good extension elongation.

Claims

A kind of pitch tightener is characterized in that: regulate bolt and head on the pearl that bumps in the overcoat, bump pearl again with bump clamping and touch.
