Description

A locking device for a door closer

technical field

The utility model relates to the field of door closers, in particular to a stop device.

Background technique

The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door, which can ensure that the door is closed to the initial position accurately and in time after it is opened. . And in order that the door closer can have the function of stopping, so that the door can realize the function of normally opening, as the Chinese patent application number 01218535.3, the name is called "two-way hidden automatic door closer", this door closer realizes the used function of stopping The parts to be seen include slide rails, stoppers, and rocker arms. The stoppers are installed on the slide rails. One end of the rocker arm is provided with roller pins and rollers. When in use, the roller pins are locked with the stoppers. And realize stop position, when needing to remove stop position, need door close a small angle, make roller pin break away from stop device back door to close automatically. There are following deficiencies in the structure that adopts this way to realize the stop function: one, when the door needs to be closed, the door only needs to be closed at a certain angle, so that the door is blown by a strong wind or people accidentally touch the door during use. It will automatically close, and the stability of the stop is not good enough; the second is that when the door closer does not need the stop function, it needs to be removed to realize the stop, which is less convenient. Based on the above-mentioned deficiencies, it is very necessary to improve the stop structure on the door closer.

detailed description

As shown in Figure 1, a parking device for a door closer according to the utility model includes a slide rail 2, a pull arm 3, a slider 4, a mounting seat 5, a stop rod 6, an adjusting bolt 7, and a stop block 8 , fixing bolt 9, wherein as shown in Figure 3, described mounting base 5 is made with inserting hole 51, also made on this mounting base 5 the elongate hole 52 that communicates with inserting hole 51, in mounting base Mounting holes 53 are also made on the 5; as shown in Figure 5, the stop block 8 is composed of two spacer plates 81 and a top plate 82 connecting the two spacer plates 81, and the two spacer plates 81 and the top plate 82 forms a limit groove 83; as shown in Figure 4, the slide rail 2 is made with a chute 21, and the bottom surface of the slider 4 is made with an embedded groove 41, and the two groove walls of the embedded groove 41 are respectively made There is a through hole 42 corresponding to the notch of the limit groove 83; as shown in Figure 1, the stop block 8 is embedded in the embedded groove 41, and is installed in the chute 21 together with the slider 4, One end of the pull arm 3 is hinged on the slider 4 to pull the slider 4 to move back and forth in the slide rail 2. In the actual implementation process, as shown in Figure 10, the other end of the pull arm 3 will be hinged After the locker body 1 is provided; as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, and Fig. 5, the mounting base 5 is embedded in the chute 21, and the fixing bolt passing through its mounting hole 53 9 fixed, the mounting base 5 can be installed in any position of the chute 21 through the fixing bolt 9; one end of the stop rod 6 is inserted into the insertion hole 51 of the mounting base 5, as shown in Figure 2, the stop The cross-section of the moving rod 6 is made into a regular hexagonal structure, and one of the ends of the stop rod 6 becomes a cone-shaped structure. Through the design of the cone-shaped structure, it plays the role of alignment, so that the utility model will not stop during use. The moving rod 6 is easily aligned with the through hole 42 of the limiting groove 83, and is more easily inserted into the through hole 42; And be fixed on the top surface of stop bar 6, stir adjustment bolt 7 to drive stop bar 6 to rotate, make the variation of stop bar 6 section width cooperate with stop block 8 to realize opening or closing.

The working principle of the utility model is roughly as follows: when the door closer needs to stop, as shown in Figure 6 and Figure 7, the adjustment bolt 7 is vertically upward, and the top surface of the stop rod 6 will be parallel to the groove bottom of the chute 21 , so that the width C of the cross section of the stop rod 6 is greater than the width D of the stop groove 83, so that during the movement of the slider 4 in the chute 21, the stop plates 81 on both sides of the stop groove 83 will be blocked by the stop rod 6 Withstand the slide block 4 to stop moving, so as to achieve the function of stopping. With such a structure, the door will not be closed under the action of external force, so that the utility model has the advantages of simple structure and good stability; when the door is closed When the device does not need the stop function, as shown in Figure 8 and Figure 9, it is only necessary to turn the adjusting bolt 7 to make the stop lever 6 rotate, so that the original top surface of the stop lever 6 will be inclined, so that the stop lever 6 Two parallel sides are formed on both sides of the side, and the distance E between the two sides is less than the width D of the limit groove 83, so that the stop rod 6 can pass through the stop block 8, so that the utility model is equipped with When the door closer does not need the stop function, it only needs to toggle the adjusting bolt 7, and the stop device does not need to be removed, which is convenient to use.

In order to prevent the fixing bolt 9 from touching the stop rod 6 during the installation process, so that the stop rod 6 will not rotate or the rotation is hindered, as shown in Figure 2, the other end of the stop rod 6 is made with a The ring groove 61, the fixing bolt 9 passes through the mounting hole 53 and the ring groove 61 and is pressed against the bottom of the slide groove 21.
