CN2929109Y - Button positioning structure of door closer - Google Patents

Abstract

The utility model discloses a button-type positioning structure of a door closer, which comprises a pair of clamping pieces containing a middle piece and being bolted to a button, and a telescopic arm of the door closer is connected with a positioning piece in series; when the button is pressed, the pair of clamping pieces are linked to descend and push the positioning piece to tilt, and the telescopic arm is stretched by applying force to push a door leaf, and when the force is removed, the inclined positioning piece will clamp the telescopic arm so that it cannot be retracted, thereby generating a door leaf positioning action; and when force is applied to the door leaf again, the telescopic arm is stretched again, and the positioning piece is pushed back to its original position by a spring behind the positioning piece, thereby releasing the clamping relationship of the telescopic arm so that the door can be closed and restored.

Description

Button positioning structure of door closer

technical field

The utility model relates to a positioning structure, in particular to a button-type positioning structure of a door closer that can position a door leaf at any opening position and angle.

Background technique

In order to provide a more convenient life, the manufacturer has developed a door closer structure, which is basically a pneumatic cylinder structure, which is installed on the door bucket and the other end is fixed on the door leaf. After opening the door leaf, the stretched telescopic arm and spring store energy. After the external force of pushing the door leaf is removed, the door leaf can be pulled back to the position to achieve the purpose of automatic door closing.

However, there are many times when it is necessary to temporarily stop the door leaf at a specific opening position, so that most people pass, carry things, etc., in order to achieve this functional purpose, the existing structure once designed a positioning piece with a perforation and was worn on the On the telescopic arm of the door closer, when the door leaf reaches the desired stop position after the door is opened, you can manually move the positioning piece to tilt it so that its perforation obliquely engages the telescopic arm, so that the telescopic arm cannot be retracted. The purpose and effect of keeping the door leaf at a specific position.

However, according to actual use experience, it has been found that although the above-mentioned door closer structure that allows the door leaf to stay at a specific position has practical effects, when the door leaf is to be closed, it is necessary to reach out and move the positioning piece to return to the original position. Such a positioning Both setting and release must be achieved by reaching out and moving the positioning piece to achieve the predetermined action and effect. In practice, we often find that we have to reach out to operate the action. If we are carrying objects, it will often cause great inconvenience, and more often The problem found is that fingers are often accidentally pinched during the process of stretching and retracting the positioning piece, causing trouble and inconvenience; how to solve this problem is really worth solving.

In view of this, the creators of this case have made in-depth research on this requirement, and developed a button-type positioning structure for the door closer of this case. After field trial and verification, it was found that it can effectively achieve the established practical goals, and it is an ideal. new creations.

Utility model content

The purpose of this utility model is: to change the current structure of the door closer by providing a button-type positioning structure of the door closer. If the existing discovery requires the user to reach out to operate, it will often cause great inconvenience if the process of carrying objects, etc. The more often found problem is that fingers are often accidentally pinched during the process of stretching and retracting the positioning piece, causing trouble and inconvenience, so that the door leaf can be operated to be positioned at any opening position and angle, and it will not cause trouble. Shortcomings such as clamping hands effectively solve the lack of existing structures. .

The utility model is realized by adopting the following technical means:

A button-type positioning structure of a door closer. The door closer has a cylinder body, one end of which is closed and the other end is an open end.

A central perforation is provided at the closed end, and its open end is combined with the open end of the cylinder of the door closer; The piercing hole is provided with two parallel pieces on both sides of the hole, and a ㄇ-shaped stopper is set at the opening of the piercing hole; a clamping piece composed of two pieces and its joint can be placed in the piercing hole. An intermediate piece is included, the double clamping pieces are of the same shape, with a shaft hole at a top angle position, and an arc-shaped return hole in the body; and the middle piece is at the same top angle position There is also a shaft hole, and the position of the arc-shaped return hole of the sheet body corresponding to the clamping sheet is provided with a slit to form an arc-shaped body, and a spring is connected in series;

The double clamping piece holds the middle piece symmetrically, and is inserted into the aforementioned and penetration hole, and a button is placed outside the penetration hole, and the button, double clamping piece and The middle piece, and the spring of the middle piece can be accommodated in the arc-shaped return hole of the double clamping piece, and the double clamping piece is combined with the button to move, and the middle piece is fixed in the button type within the positioning structure;

A spring and a positioning piece with a central perforation are connected in series at the open end of the telescopic arm;

The above-mentioned door closer is combined with the button-type positioning structure of this case, and its telescopic arm passes through the middle perforation of the closed end of the button-type positioning structure, and the positioning piece connected in series is in the button-type positioning structure, and is held by the lower end of the middle piece. Click the positioning piece to position.

Compared with the prior art, the utility model has the following obvious advantages and effects:

The utility model is a button-type positioning structure of a door closer. When the button is pressed, the double clamping pieces below are lowered in conjunction and pushed against the positioning piece to tilt, and the telescopic arm is stretched by pushing the force of the door leaf. , the tilted positioning piece will catch the telescopic arm so that it cannot be retracted, resulting in a positioning action of the door leaf; and when the force is applied again, the door leaf will be stretched again, and the spring behind the positioning piece will push the positioning piece back to its original position , and release the locking relationship of the telescopic arm so that it can close the door and return. The above structure and operation method make it possible to operate the door leaf to be positioned at any opening position and angle, and it will not have shortcomings such as pinching hands, which effectively solves the existing problems. lack of structure.
