The door closer main body 1 is installed on the door DR, the guide rail 4 is installed on the top lower surface of the door frame DF, the slidable slider 3 is arranged in the guide rail 4, the slider 3 is hinged with one end of the rocker 2, and the other end of the rocker 2 is hinged with the door closer main body 1, so that the slider 3 is linked with the opening and closing of the door DR. The door closer body 1 accumulates energy during the opening of the door DR, and when the opening power of the door DR is removed, the door closer body 1 releases the accumulated energy to close the door DR. If the slider 3 is stopped in the guide rail 4 after the door DR is opened by a certain angle, the door DR can be stopped in an opened state.
As shown in fig. 2, the slider 3 is slidably disposed in the guide rail 4, and the slider 3 can slide left and right in the guide rail 4. The slide block 3 is linked with the opening and closing of the door (see fig. 1), and the slide block 3 slides leftwards in the door opening process; during the closing of the door, the slider 3 slides to the right.
The locking mechanism 5 is used to stop the slider 3. The inner frame 17 is a part of the lock mechanism 5, and other components of the lock mechanism 5 are mounted on the inner frame 17.
The guide rail 4 is a profile. The guide rail 4 is provided with an inner cavity 18 therein, the inner frame 17 being mounted in the inner cavity 18, the inner cavity 18 extending to at least one end of the guide rail 4 so that the inner frame 17 can be inserted into the inner cavity 18 from one end of the guide rail 4. The inner frame 17 is slid to a set position in the inner cavity 18 and secured with a set screw 19. The inner frame 17 is fixed with a fixing block 20 through a rivet 21, a fixing screw 19 is screwed on the fixing block 20, and the front end of the fixing screw 19 is tightly propped against the guide rail 4, so that the inner frame 17 can be basically fixed at any position in the guide rail 4, and the position of the inner frame 17 can be accurately adjusted by matching with the installation environment. Or the inner frame 17 can be provided with a fixing screw 19. The inner frame 17 is matched with the guide rail 4, so that the installation, the position adjustment of the inner frame 17 and the later-stage disassembly and maintenance are convenient.
The locking mechanism 5 includes a parking member 6, a drive unit 7, and a dial 9. The stop 6, the drive unit 7 and the shifting block 9 are all arranged on the inner frame 17.
The stopper 6 has a first rotary shaft 10, the first rotary shaft 10 is journaled to the inner frame 17, and a first portion 12 and a second portion 13 are integrally provided on both sides of the first rotary shaft 10, respectively. That is, the first portion 12 and the second portion 13 are fixed, and the first portion 12 and the second portion 13 are respectively rotatably disposed with respect to the first rotating shaft 10.
The first portion 12 is arranged to be limited to the slider 3, and can block the slider 3 from moving when the first portion 12 rotates to be located in the moving path of the slider 3. The second portion 13 extends upwardly. The moment of gravity of the first portion 12 relative to the first axis of rotation 10 is greater than the moment of gravity of the second portion 13 relative to the first axis of rotation 10, so that the first portion 12 naturally sags and the stop 6 has a tendency to rotate clockwise. A stop 11 is also arranged on the rotation path of the stop member 6, and the stop 11 is stopped at the right side of the second part 13, so that the clockwise rotation trend of the stop member 6 is overcome. In this example, the stop 11 is stamped and formed from the inner frame 17, and in other embodiments, the stop 11 may have other forms, such as a block fixed to the inner frame 17 by a mounting method.
The driving unit 7 is similar to a tail pressing portion of a pressing type ball-point pen, and is of a structure well known in the art. The drive unit 7 comprises a push rod 8, and the push rod 8 can be switched between a first position (extending to the right in the state of fig. 2) and a second position (retracting to the left in the state of fig. 3) by pressing the push rod 8 in sequence. In this example, the pressing operation is performed by the slider 3.
The dial 9 has a second rotation shaft 14, and the second rotation shaft 14 is coupled to the inner frame 17. The dial 9 further comprises a third portion 15 and a fourth portion 16 integrally formed with each other, and the third portion 15 and the fourth portion 16 are both rotatably disposed with the second rotating shaft 14. The third portion 15 is linked to the push rod 8, i.e. the third portion 15 rotates as the push rod 8 moves. In this example, the linkage is realized by overlapping the third part 15 on the front end of the push rod 8, and in this case, when the slide block 3 moves leftwards, the third part 15 and the push rod 8 can be pushed simultaneously, so that the linkage is realized without other parts, and the structure is simple. In other embodiments, the pusher 9 may be coupled to the push rod 8 in other ways, such as by hinging the third portion 15 to the push rod 8.
In this example, the dial 9 has a clockwise rotation tendency, and the fourth portion 16 and the third portion 15 both have a clockwise rotation tendency to the dial 9 relative to the second rotation axis 14, so that the third portion 15 can naturally abut against the front end of the push rod 8.
A fourth portion 16 of the paddle 9 extends towards the parking member 6. When the paddle 9 is rotated from the state shown in fig. 2 to the state shown in fig. 3, the front end of the paddle 9 is positioned on the left side of the second portion 13, thereby restricting the stopper 6 from rotating counterclockwise. Fig. 2 and 3 show the parking member 6 in a locked state, and when the parking member 6 is rotated counterclockwise, the parking member 6 is in an unlocked state. The angular range of counterclockwise rotation of the stop 6 can be controlled at 15 °. As shown in fig. 3, after the sliding block 3 abuts against the first portion 12 rightwards, the second portion 13 abuts against the fourth portion 16, and the force direction of the fourth portion 16 passes through about the axis of the second rotating shaft 14, so that the shifting block 9 can be maintained in the state shown in fig. 3 more stably, and at this time, when the door is subjected to a large door closing force, the sliding block 3 cannot push the stopper 6 away from the locking state shown in fig. 3.
The working principle is as follows:
as shown in fig. 2, when the door is closed, the slider 3 moves leftwards in the guide rail 4, and the parking member 6 is in a locked state;
after the sliding block 3 is contacted with the first part 12 of the stop part 6, the stop part 6 is stirred, the stop part 6 rotates anticlockwise, the stop part 6 is switched to an unlocking state, the sliding block 3 can continuously move leftwards and enter the position below the stop part 6, and at the moment, the push rod 8 is in a first position (the state of fig. 2);
the slider 3 continues to move leftwards and simultaneously pushes the third part 15 and the push rod 8, after the door closing power is released, the slider 3 moves rightwards due to the action of an energy storage mechanism (spring) in the door closer main body 1 (see fig. 1) so as to release the third part 15 and the push rod 8, and then the push rod 8 is in a second position (the state of fig. 3), the driving unit 7 and the push rod 8 are similar to a tail pressing part of a ball pen, so that when the push rod 8 is pressed in sequence, the push rod 8 can be switched in sequence between the first position shown in fig. 2 and the second position shown in fig. 3;
as shown in fig. 3, after the shifting block 9 rotates, the fourth portion 16 abuts against the left side of the second portion 13, and the counterclockwise rotation of the stop member 6 is limited, so that the stop member 6 is maintained at the locking position shown in fig. 3, the slide block 3 is abutted against the right end by the stop member 6 and stops, the slide block 3 cannot move further to the right, and the door is stopped at an open position;
and applying the door opening power again to enable the sliding block 3 to move leftwards again, pressing the push rod 8 once, removing the door opening power, enabling the sliding block 3 to move rightwards, converting the push rod 8 into the state shown in the figure 2, pushing the shifting block 9 by the push rod 8, enabling the shifting block 9 to withdraw from the stop part 6 (as shown in the state of the figure 2), enabling the sliding block 3 to shift the stop part 6 to rotate anticlockwise, enabling the sliding block 3 to be separated from the stop part 6 to move rightwards, and achieving door closing.
The door closer has the advantages that:
1) the sound can be reduced, and the mute effect can be achieved;
2) because the power support is not needed, the energy is saved and the environmental protection is facilitated;
3) because the power supply does not depend on electric power, the failure caused by power failure is avoided, and the stability is higher;
4) since the slide block is released from moving back and the push rod is only needed to be moved again, the movement can be realized without too much force, and the door can be easily released from a stop state.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
