Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a door closer for opening and/or _-threshold. [Prior Art] There are various well-known door closers and simple implements in the technology. In a simple two-spring accumulator, the force is accumulated by opening the door by hand. Automatically close the door. In the other-type construction, the door is opened and closed, for example, part or all of the - electric drive negative suspension. A spring force accumulator accumulates power when the door is opened, and provides assistance when the door is closed. SUMMARY OF THE INVENTION It is also an object of the present invention to provide a door closer that is simple and inexpensive to manufacture, and that is suitable for (4) armoring and has low maintenance requirements. In particular, the object of the invention is to provide a simple and reliable connection between the inner-cam plate unit and a piston bore of the door closer. The purpose of the invention is achieved by requesting the patent paradigm. Other beneficial developments in this month are found in the various sub-items of the scope of application for patents. The object of the invention is thus achieved by a door closer comprising a kinetic-door slamming connection, a cam disc on the drive shaft, and a cam plate unit for at least two power transmission rollers. The cam plate unit is located on the cam plate "JL" on the cam path of the cam plate, and a movable ilii-M spring minus drive 11 is coupled to the cam plate unit. The _ reed shaft is designed to measure the piston rod. The connection between the cam plate unit and the piston rod includes a connecting bolt that screws the piston rod along the piston = axis. The connecting bolt is thus horizontal relative to the position of the door closer, and the connecting bolt is connected to the cam plate unit so as to have a male thread. The piston rod has a female thread that corresponds to the male thread. On the one hand, the connection between the cam plate unit and the piston rod of the present invention is very easy to install, and it is extremely flexible when the connecting bolt is screwed into the piston rod. On the other hand, it can be designed to resist. In addition to the traditional door closer, the so-called "HII" also includes the η operator and the vocabulary assisted door operation 11. The door operator and the 鄕-assisted operator can be electro-hydraulic, and electric and mechanical. In a preferred embodiment, the connection between the cam plate unit and the piston rod includes a connector member that is vertically inserted relative to the longitudinal axis of the piston rod. To this end, the cam plate unit overlaps with the connecting bolt, and the connecting member is simultaneously inserted into the cam plate unit and the connecting bolt in this overlapping region. For this purpose, the connecting bolt preferably comprises two parts. The first part of the connecting bolt has a male thread and the front is screwed into the piston rod. The second portion of the connecting bolt projects beyond the piston rod and overlaps the cam plate unit. Preferably, the through hole of the remaining cam plate unit and the connecting bolt is connected. The through-opening preferably extends perpendicularly relative to the longitudinal axis of the piston rod while extending horizontally relative to the final installation position of the door closer. It is also advantageous that the cam plate unit has an upper connecting plate and a pair of upper connecting plates to maintain a distance from the lower connecting plate. Preferably, the two webs are located in two horizontal planes that are parallel to each other. Since the upper connecting plate maintains a distance from the lower connecting plate, the force transmitting roller can be inserted between the two connecting plates. It is further advantageous that the connecting bolt is located between the upper connecting plate and the lower connecting plate. In this case, the connecting member preferably functions both with the upper connecting plate and the lower connecting plate, and also with the connecting bolt. It is particularly advantageous that the through hole extends from the upper connecting plate through the connecting bolt and passes through the lower connecting plate. A connector can be inserted into the through hole. It is particularly advantageous that the distance between the upper web and the lower web corresponds to the thickness of the connecting bolts in the overlap region. Thus, the upper connecting plate rests on the top of the connecting bolt. The lower connecting plate is against the bottom side of the connecting bolt. In a preferred embodiment, the upper web and the lower web are two identical structural members. The two structural members are specially manufactured by stamping or other suitable processes, for example, 201144561 such as laser (four), money (four) pressure (fine_bIankingh manufacturing components reduce manufacturing and storage costs 1 by using the connector in the preferred example, the lower connecting plate and upper The 10,000 connection board is connected to the connection, the upper connection is not connected to the tree (4) to the lower connection board. In particular, the expensive threads and screws used in the lower connection plate in the prior art can be omitted and the installation is simplified. The real patch, in the overlapping area, is designed to be a horizontal plate, with a draped shirt, as a connection receiving hole. From the perspective, this horizontal configuration can have both a square contour and a contour It is optimized according to the force flow. In the preferred solid blue, the connecting piece is designed as a bolt, or a screw: or designed as a -_. The job is recorded, and the special position is tightly matched = I: "卩插. In the embodiment, the screw and the nut are included, the screw insertion hole unit and the through hole of the connection screw inspection, and the screw cam plate unit is below or in another-miniature design, above Connection plate or lower connection plate is set to ', grain For example, it can be screwed into a screw without a nut. = The outer advantage is that the door closer is located in the casing towel, and a piston is provided on the piston rod. In this example, the advantage is that the closing spring is configured as follows: In the case of facing the cam disc Y side, the closing spring abuts against the casing. In this case, it is preferred to close the spring; the "piece. The piston rod extends from the cam plate unit to close the spring. = the other side of the spring" - the piston The secret plug. On the side of the city, close the magazine directly to the piston by the middle cymbal. The moving cymbal moves the drive shaft. The force shift is transmitted from the cam disc to the force transfer roller 0 cam plate unit and thus horizontal At the same time, the piston rod and the piston fixed on the cam plate unit are moved, and when the door is opened, the 'spring* is subjected to the pre-force. When the door is closed, the spring is stretched again, and the piston and the wire plate unit including the piston rod are pushed. The direction of the person is reduced. (4) The cam disc, this linear motion is rotated by the switching surface. 201144561 In another preferred embodiment, the closing spring is not used, or the closing of the spring is set, the driver is included. Motor, oil Secret - the oil pressure in the casing b. This electric motor drives the oil pressure. The oil wire supplies the oil pressure liquid to the pressure chamber. Preferably, the pressure chamber is directly located in the piston, so that the piston and the piston rod and the cam plate unit are under pressure. [Embodiment] FIG. 2 and FIG. 2 show a door closer 实施-embodiment of the present invention. For this reason, FIG. 1 shows a part of the door closer i in a sectional side view. The cam plate unit closed in the casing 2 4'-Connected-the spring 9 stopper rod 8 located in the casing 2 extends to the right beyond the squid 9 and is not outputted in the figure -. At the right end of the closing spring 9, a piston is attached to the piston rod 8. The left end of the closing spring 9 is pressed against the casing 2 via the art piece 23. The piston rod 8 extends along its longitudinal axis 24. The cam plate unit 4 comprises an upper connecting plate 5 and a lower connecting plate & Parallel to each other and as shown in the figure, the cam plate unit 4 is connected to the piston rod 8 via a connecting bolt 10. The connecting bolt 1〇 includes two parts. The first portion of the bolt is designed to be a threaded shank 18. The threaded check ig is screwed into the live scale 8 in the horizontal direction along the longitudinal axis 24. The connecting bolts 1 are additionally formed into a horizontal disk 19. This horizontal disk 19 is parallel to the cam plate unit 4, between the nano connecting plate 5 and the lower connecting plate 6. The area where the upper connecting plate 5, the water 19, and the tens of thousands of connecting plates 6 overlap is referred to as an overlapping portion 17. Here, the first through-holes are provided in the upper connecting plate 5, and two through holes 13 are provided in the horizontal disk 19. The third through hole is disposed in the lower connecting plate 6 and the three identifying holes 13 and 14 are perpendicular to each other, and the three through holes 12, 13, and 24 are perpendicular to the door closer! Final installation location. - The connecting piece is a bolt-and-bolt that passes through the three through-openings 12, i3, 14, and thus the upper connecting plate 5 of the 201144561, passes through the connecting bolt 10, and passes through the lower connecting plate 6. The connector 11 includes a handle 15 and a head 16. The outer diameter of the shank 15 corresponds approximately to the diameter of the through holes 12, 13, 14. The head 16 of the connector ^ is seated on top of the upper connecting plate 5. Figure 1 additionally shows the thickness D of the horizontal bolt 19 of the connecting bolt 10. This thickness D extends perpendicular to the longitudinal axis 24 and is perpendicular to the final mounting position of the door closer. This thickness D corresponds to the gap between the upper connecting plate 5 and the lower connecting plate 6. As can be seen from Fig. 1, a first force transmitting roller 7 and a cam disc 3 are located between the upper connecting plate 5 and the lower connecting plate 6. This cam disc 3 is mounted on the output shaft of the door closer 1 in a manner that is not subject to torque. This output shaft is in turn connected to a threshold, for example via an arm assembly. The cam plate unit 4 and its details connected to the piston rod 8 are shown in FIG. The upper connecting plate 5 is left blank in Figure 2. Therefore, it is easy to see that the first force transmitting roller 7, the second force transmitting roller 20, and the third force transmitting roller 21 are located in the cam plate unit 4. The three force transfer rollers 7, 20, 21 are distributed for a slot 22. The groove 22 is provided in both the upper connecting plate 5 and the lower connecting plate 6. The drive shaft of the door closer extends through the slot 22 and is perpendicular to the cam plate unit 4. Depending on whether the door closer 1 is left-handed or right-handed, the cam plate 3 is in contact with the second force transmitting roller 2〇 or with the third force transmitting roller 21. Further, Fig. 2 shows in plan view that the horizontal disk 19 of the connecting bolt 1 has a square outline. The horizontal disk 19 thus has an excellent adaptability to the contour of the cam plate unit 4. The length of the three through holes 12, 13, 14 and the threaded shank 18 is preferably selected such that the piston rod 8 abuts against the cam plate unit 4. This embodiment clearly illustrates how the connection between a cam plate unit 4 and a piston rod 8 can be designed in a very low cost, easy to install, and flex resistant manner.
