Definitions
- the present invention relates to a lock, more particularly, to a lock cylinder of a mechanical cylinder lock having a function of preventing unauthorized opening by a bump key, and especially to a lock cylinder of a mechanical cylinder lock having a function of preventing unauthorized opening through strong bumping of a bump key.
- An object of the present invention is to disclose a lock cylinder which is simple in structure, easy to manufacture, and has a function of preventing unauthorized opening through strong bumping of a bump key.
- Said anti-bumping pin in the pin channel of the lock cylinder barrel is ⁇ -shaped, and said anti-bumping pin has a smaller diameter in its upper and lower portions than that in its middle cylindrical portion.
- the shape and dimension of said pin channel of the lock cylinder barrel in which the ⁇ -shaped anti-bumping pin is provided matches the shape and dimension of said anti-bumping pin.
- a cylindrical thin pin is interposed between each spring and upper pin.
- the cylindrical thin pin is capable of increasing the compression force of the spring and thus the elastic force accumulated in the spring.
- the cylindrical thin pin can increase the resistance force when bumping out the pins of the lock cylinder barrel by a bump key. Even if the bump key bumps the pins of the lock cylinder barrel strongly, the lock cylinder according to the present invention can prevent any unauthorized opening by the bump key, so that it considerably increases assurance coefficient of the lock cylinder of the cylinder lock and ensures security.
- a 4-anti function of being anti-prizing, anti-drilling, anti-drawing and anti-bumping can be achieved so as to produce a mechanical cylinder lock having the 4-anti function. Therefore, the invention is applicable to all the mechanical lock cylinders.
- An anti-bumping lock cylinder comprises a lock cylinder barrel or plug 1 ( Fig. 1 ), a lock cylinder housing 6 , twelve columns of pin channels in two rows in the lock cylinder barrel 1 and the lock cylinder housing 6, which are arranged in communication with each other, lower pins 2 in the pin channels of the lock cylinder barrel 1, cover pins 5 at the top of the pin channels of the lock cylinder housing 6, springs 4 beneath the cover pins 5, upper pins 3 disposed in the pin channels of the lock cylinder housing when the lock cylinder is opened, and a key hole 7; characterized in that an anti-bumping pin 2' is provided in each of two columns (the second and fifth column in both the left and right rows) of each row (each row having six columns) of the pin channels of the lock cylinder barrel 1, the anti-bumping pin 2' being suspended in the pin channel of the lock cylinder barrel 1, the upper edge of the anti-bumping pin 2' being lower than the plane of the lock cylinder barrel and the lower edge of the anti-bumping pin
- Said anti-bumping pins 2' in the pin channel of the lock cylinder barrel 1 are ⁇ -shaped, and said anti-bumping pins have a smaller diameter in their upper and lower portions than that in their middle cylindrical portion ( Fig. 3 ).
- the shape and dimension of said pin channels of the lock cylinder barrel 1 in which the ⁇ -shaped anti-bumping pins 2' are provided matches the shape and dimension of the anti-bumping pins.
- the present invention is applicable to all the mechanical lock cylinders.
- the I-shaped upper pins 3'as shown in Figs. 1 and 4 are anti-prizing pins.
- the lock cylinder has an anti-prizing function. If the invention is combined with other technologies for other functions such as anti-drilling and anti-drawing functions (prior art), the lock cylinder of the mechanical cylinder lock cylinder may have a 4-anti function of being anti-prizing, anti-drilling, anti-drawing and anti-bumping.
- the pin channels in the lock cylinder barrel 1 and the lock cylinder housing 6 which are arranged in communication with each other can be arranged as twelve columns in two rows, or a plurality of columns in one row.
- anti-bumping pins 2' are provided in pin channels of the lock cylinder barrel 1 and cylindrical thin pins 9 are provided beneath the springs 4 in the pin channels of the lock cylinder housing 6, both of which belong to the solution of the present invention.
