Abstract
The utility model discloses a safety door electromagnetic lock which mainly comprises a support, a lock cylinder shaft and a rolling friction assembly which is installed between the support and the lock cylinder shaft in a matched mode. The safety door electromagnetic lock can overcome the defects that in the prior art, guiding efficiency is low, anti-jamming capability is poor and stability is poor, and has the advantages of high guiding efficiency, strong anti-jamming capability and good stability.
Description
Technical field
The utility model relates to the security protection equipment technical field, particularly, relates to a kind of safety door electromagnetic lock.
Background technology
At present, the safety door electronic lock is widely used in subway station, the railway terminal.Safety door electronic lock as shown in Figure 1 comprises support 1, and cooperates fixed cover 2, axle sleeve 3 and the lock core shaft 4 of installing with support 1; Axle sleeve 3 is sleeved on lock core shaft 4 peripheries, and fixed cover 2 is sleeved on axle sleeve 3 peripheries and is installed on the support 1.
But existing safety door electronic lock adopts the mode of axle and axle sleeve (as axle sleeve 3) guiding on 1 on lock core shaft 4 and support, and frictional resistance is big, a little less than the moment of resistance ability, a little less than the antijamming capability.
In realizing process of the present utility model, the inventor finds to exist at least in the prior art that guiding efficient is low, antijamming capability weak and defective such as poor stability.
Summary of the invention
The purpose of this utility model is, at the problems referred to above, proposes a kind of safety door electromagnetic lock, to realize guiding efficient height, antijamming capability by force and the advantage of good stability.
For achieving the above object, the technical solution adopted in the utility model is: a kind of safety door electromagnetic lock mainly comprises support and lock core shaft, and cooperates the rolling friction assembly that is installed between described support and the lock core shaft.
Further, described rolling friction assembly comprises the linear bearing that is sleeved on described lock core shaft periphery, and the axle sleeve that is sleeved on described linear bearing periphery; Described axle sleeve cooperates rack-mount.
Further, described linear bearing comprises the cylinder axis that arranges near axle sleeve, and evenly at interval and be symmetricly set on a plurality of carrying steel balls between cylinder axis and the lock core shaft.
The safety door electromagnetic lock of each embodiment of the utility model, owing to mainly comprise support and lock core shaft, and cooperate the rolling friction assembly that is installed between support and the lock core shaft; Can replace sliding friction with rolling friction, make the efficient of guiding higher, antijamming capability is stronger, is conducive to improve the stability that lock core shaft slides; Guiding efficient is low in the prior art, antijamming capability weak and the defective of poor stability thereby can overcome, to realize guiding efficient height, antijamming capability by force and the advantage of good stability.
Other features and advantages of the utility model will be set forth in the following description, and, partly from manual, become apparent, perhaps understand by implementing the utility model.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of manual, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of existing safety door electronic lock;
Fig. 2 is the structural representation of the utility model safety door electronic lock.
By reference to the accompanying drawings, Reference numeral is as follows among the utility model embodiment:
The 1-support; The 2-fixed cover; The 3-axle sleeve; 4-lock core shaft; The 5-linear bearing.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
According to the utility model embodiment, provide a kind of safety door electromagnetic lock.As shown in Figure 2, the safety door electromagnetic lock of present embodiment mainly comprises support 1 and lock core shaft 4, and cooperates the rolling friction assembly that is installed between support 1 and the lock core shaft 4.
Above-mentioned rolling friction assembly comprises the linear bearing 5 that is sleeved on the lock core shaft periphery, and the axle sleeve 3 that is sleeved on linear bearing 5 peripheries; Axle sleeve 3 cooperations are installed on the support 1.This linear bearing 5 comprises the cylinder axis that arranges near axle sleeve, and evenly at interval and be symmetricly set on a plurality of carrying steel balls between cylinder axis and the lock core shaft.
The safety door electronic lock of above-described embodiment adopts the mode of rolling friction to replace sliding friction in lock core shaft 4 and 1 on support, makes the efficient of guiding higher, and the efficient that lock core shaft is led is higher, antijamming capability is stronger, lock core shaft slides more stable.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
