Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing and by specific embodiment, and following embodiment is only descriptive, not limiting, can not limit protection scope of the present invention with this.

[0036] An electric auxiliary lock, including a base plate 1, on the bottom of the base plate 1 is provided with grid reinforcement ribs 11, which avoids unfavorable factors such as air holes, trachoma, and deformation during casting, and ensures the original structure while reducing weight. While having high strength, it is more convenient for later machining and assembly, and at the same time, the installation contact surface of the overall lock is optimized, that is, when in contact, it can cooperate with the concave surface between the reinforcing ribs, reducing the difficulty of cooperation.

[0037] Refer to attached figure 1 , 2 , is a schematic diagram of the base plate 1, a first positioning plate 12 and a second ...

Abstract

The invention discloses an electric auxiliary lock. The electric auxiliary lock meets the requirements of high air impermeability and low noise needed by double sliding plug doors. According to the technical scheme, the electric auxiliary lock is characterized in that a pneumatic element, an operating rod and a spring bolt are arranged on a base, the operating rod is provided with an operating block, and the pneumatic element drives the operating rod to rotate, enables the operating block to make contact with the spring bolt and can drive the spring bolt to realize rotation and compression. The electric auxiliary lock further comprises a first resetting mechanism enabling the operating rod to be reset and a second resetting mechanism enabling the spring bolt to be reset. The pneumatic element has the advantages that the noise is low and the air impermeability is good; according to needs, the first resetting mechanism can make the operating rod return to the unlocked state fast, and the second resetting mechanism can make the spring bolt return to the unlocked state fast.

Description

technical field [0001] The invention relates to the field of rail car door locks, more specifically, it relates to an auxiliary lock for a rail car double-opening plug-and-pull door system. Background technique [0002] Electric double sliding door is mainly used for the door of high-speed trains. The current electric double sliding door system mainly meets the strength requirements, noise requirements and sound insulation and heat insulation indicators of the door system. When the vehicle enters and exits the tunnel and intersects with the 200km / h train, the air pressure will cause discomfort to passengers such as tinnitus. Therefore, it is particularly important to pressurize the door to maintain airtightness. [0003] For example, the patent with the publication number CN103742008A discloses an electric auxiliary lock, which includes a lock body, on which a deceleration motor, a planetary deceleration clutch mechanism, an inner swing arm, and a dead bolt are arranged in s...
