Problems solved by technology

[0002] The existing U-shaped alarm lock has the following deficiencies: on the one hand, the lock rod and the alarm device of the existing U-shaped alarm lock are of an integrated structure, which makes the alarm device difficult to maintain and replace; on the other hand, the existing U-shaped alarm lock One end of the lock bar of the lock is not connected to the lock beam, but to the alarm device, which destroys the integrity of the U-shaped lock, reduces the overall strength of the lock, and greatly reduces the anti-theft performance
And, once the alarm device is damaged, the whole lock is also scrapped simultaneously, thereby causing unnecessary waste

Embodiment Construction

[0009] Such as figure 1 As shown, the double-opening U-shaped alarm lock of the present invention includes a U-shaped lock bar 1 and a lock beam 2 . The U-shaped lock bar 1 and the lock beam 2 are connected to form a common double-opening U-shaped lock. Two button grooves 12 are provided on the lock beam 2 . The two button grooves 12 are plug-fitted with the two ends of the U-shaped lock bar 1 respectively. The upper part of one end of the lock beam 2 is horizontally provided with an inner cavity 10 . The inner cavity 10 communicates with one of the button grooves 12 . An alarm 5 and a fixed sleeve 6 are installed in the inner cavity 10 . A through hole 9 is provided in the fixed sleeve 6, and the through hole 9 communicates with the button groove 12 correspondingly. The fixing sleeve 6 cooperates with the lock beam 2 to wrap the alarm 5 completely. The inner side of the fixed sleeve 6 is provided with a button groove 11 . The button groove 11 communicates with the th...

Abstract

The invention discloses a double-opening U-shaped alarm lock. The double-opening U-shaped alarm lock comprises a U-shaped lock rod and a lock beam; two button slots are formed in the lock beam and are respectively matched with two ends of the U-shaped lock rod by inserting; an inner cavity is horizontally formed in the upper part of one end of the lock beam and is communicated with one button slot; an alarm and a fixing sleeve are mounted in the inner cavity; a through hole is formed in the fixing sleeve and correspondingly communicated with each button slot; the fixing sleeve and the lock beam are matched to wrap the alarm completely; another button slot communicated with the through hole is formed in the inner side of the fixing sleeve; a button is arranged on the alarm sand matched with the another button slot. According to the double-opening U-shaped alarm lock, two ends of the lock rod can be also connected with the lock beam under a locking state, so that the integrity and firmness of the U-shaped lock can be ensured, and as a result, the alarm can be stopped until the lock is opened in an accurate manner, and the antitheft effect is improved; the integrity is improved; after an alarming device is removed, a lock body can be used as a general U-shaped lock. The double-opening U-shaped alarm lock further has the advantages of being simple in structure, low in manufacturing cost and simple and convenient to use.

Description

technical field [0001] The invention relates to a lock, specifically a double-opening U-shaped alarm lock. Background technique [0002] The existing U-shaped alarm lock has the following deficiencies: on the one hand, the lock rod and the alarm device of the existing U-shaped alarm lock are of an integrated structure, which makes the alarm device difficult to maintain and replace; on the other hand, the existing U-shaped alarm lock One end of the lock bar of the lock is not connected with the lock beam, but is connected with the alarm device, which destroys the integrity of the U-shaped lock, reduces the overall strength of the lock, and greatly reduces the anti-theft performance. And, once the alarm device is damaged, the whole lock is also scrapped simultaneously, thereby causing unnecessary waste. Contents of the invention [0003] The object of the present invention is to provide a double-opening U-shaped alarm lock, whose alarm device is easy to disassemble and mai...
