New description: [New technical field] This case relates to the field of door closers, especially a device that can keep the door closer and return to the same speed. [Prior Art], according to the door closer, it can be used in various places. Please refer to the ninth figure. The door closer (5) has a pressure cylinder (50) and its telescopic arm (5丄). The cylinder (5 〇) is mounted on the door leaf, and the open end of the Lu telescopic arm is installed at the corresponding position of the door frame; when the door leaf is pushed open, the telescopic arm (5 work) is also stretched, and the end is further Connect the piston (5 2) with the check valve function to compress the spring (5 3) of the telescopic arm ($ 1), and at the same time move the piston piece (52) in the cylinder forward to the front of the majority of the air Move to the rear space of the piston piece (5 2); when the door closer closes the door return stroke, the compressed spring (5 3) springs elastically pushes the telescopic arm (5 i) and its piston piece ( 5 2 mountain) homing and then returning to the cockroach, and pushing the air behind it with the piston piece (52) to discharge the bolt (5 4) from the end of the cylinder, thus generating damping force, and slowing down the door leaf The force of the road, to achieve the purpose and effect of Ping Φ. However, according to the actual experience, it is found that the spring tension released by the spring (5 3) is greater than the damping force generated by the reverse discharge of the piston piece (52) in the red body, so that the spring is generated (5 3 ,) ^ In the stroke of Zhang's material section, the speed of the _ position is relatively large; and when the spring (Μ) elastic tension ' Η 归 归 归 才能 才能 才能 才能 才能 才能 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; The situation of the ρ in the hearing position, how to improve, it is necessary to rely on her. In view of this, the creators of this case have been engaged in the design and manufacture of related products, in-depth analysis and research, and have been developed in this case. “5 M330345 found that it can effectively achieve the practical and practical goals of the two”. [New content] The new content of this case is to provide a constant speed closing device that can achieve the same speed of the door closer return trip. It is a door closer in the form of a pneumatic cylinder, which is near the open end of the cylinder. Filling _ airtight structure, which is a support ring seat, formed around it - the concave ring road county has a large Q-shaped ring, combined with a building and a slab retention, and is located at the center of the support ring seat There is a small shackle with a small cymbal ring, and the oil enchant is set on the side, and the open end of the telescopic arm passes through the support cymbal, and the (10) ring is subsequently smashed out of the pneumatic cylinder φ cover; The pneumatic cylinder is provided with at least one air hole in a moderate position; by the telescopic arm and the piston body being stretched in the forward stroke, the air is squeezed and moved to the living cylinder body of the plug body; At the end, the air at the front end is discharged Out, and a vacuum-like state is formed between the airtight structure and the piston body to generate vacuum suction to attract the piston body, block the reverse thrust of the elastic projectile, and reduce the return speed of the telescopic arm, that is, slow down the initial speed of the door leaf to reach the whole process, etc. The purpose of the quick closing door. • [Embodiment] • Please refer to the first figure, which is a three-dimensional exploded view of the building. The creation door closer (1) * has a pneumatic cylinder (1 〇) and its telescopic arm (1) 1), at the end of the pressure red (1 〇) cylinder is open end, the other end is provided with an air through hole (work), and can be screwed with an exhaust screw check (1 〇 1) to adjust the air flow 4; the extension arm (1 1 ) is housed in the pneumatic cylinder (丄〇), and at the end of the telescopic arm (1 1 ), there is a piston body (1 2 ) having a check valve function, Its circumference is covered with a split ring (1 2 〇) stop leak and a spring (13) is connected in series. The front end is pierced from the open end of the cylinder (丄4) with a hole of 6 M330345 (14 Ο). It is characterized in that: in the "red (1 〇) cylinder body near the open end, there is a gas-tight structure (2), which includes - Supporting the t-seat (2 ◦), forming a concave loop around it (2Q 4 a, with a large 〇 裱 (21) in the north, combined with a 塾 塾 (2 2) retention, Support _ ( 2 〇) has a small perforation (2 0 !) at the center and a small (10) ring (2 3 ), and 4) on its side to increase its lubricity; The open end passes through the support ring seat (^), the small 〇 ring (23) is subsequently worn out of the pneumatic cylinder (丄〇) cover (work 4); and, in the pneumatic cylinder (10) cylinder There is at least one air hole in the moderate position (Work 5); the second picture is a sectional view of the structure of the present creation. As shown in the eighth figure, the pneumatic cylinder block (worker) of the door closer is fixed to The door leaf (3) is 'and the open end of the telescopic arm (1 1) is fixed at the corresponding position of the door frame (4); see the second and fourth figures 'When the door leaf (3) is opened, the telescopic arm (Η) is pulled out from the cylinder head cap And compressing the magazine (1 3 ) W in the forward stroke of the piston body (2) at the end of the telescopic arm (ii), because the air is squeezed and moved into the rear cylinder space of the piston body (i 2); At the end of the live substrate (12), before it The air at the end has been discharged, and a vacuum-like state is formed between the aforementioned airtight structure (2) soil (12) to generate vacuum suction and suck the piston body (12); Continuation, refer to the fifth figure, when applied After the force of the door leaf (3) disappears, the compressed elastic (13), that is, the elastic spring, generates a reverse thrust to push the telescopic arm (丄丄) and the piston body (12) to return, because the piston body (12) is vacuumed. Suction suction, which can block the reverse thrust of the magazine (i 3), and reduce the return speed of the telescopic arm (worker), that is, slow down the return speed of the door leaf (3); 2) When the air hole M330345 (15) of the pneumatic cylinder (丄〇) is passed through the continuous return stroke, the air is quickly sucked from the air hole (丄5) to the front end of the piston body (work 2) due to the pressure imbalance. Lifting the vacuum suction force on the piston body (丄2) in the vacuum space, then the elastic tension of the piston (13) is reduced due to the stretched-segment stroke, that is, the reverse thrust is reduced, so it will not suddenly Generate acceleration; see Figure 6; Continue to see Figure 7, when the piston body (work 2) passes through the cylinder gas After the hole (work 5), the cylinder and the body air are continuously pushed out through the apertures of the end through hole (i 〇〇) and the exhaust bolt (worker) to discharge the air in the cylinder to generate a damping retarding effect; By the operation of the above structure and device, the requirement of constant speed can be achieved in the return trip of the door closer, and the shortcomings of the trip speed are too fast. Anything that is related to the vacuum deceleration effect of this vacuum is within the scope of this patent. The composition of J on ^, the creation of "closed device constant speed device" has a good practical ", combined with _ sound (10) butterfly (four), give a machine _
