A kind of detachable bolt locking device
Technical field
The utility model relates to a kind of bolt locking device, in particular to a kind of detachable bolt locking device.
Background technique
Box house has electrical component, for convenience maintenance construction, and there are two case lids for tool.Maintenance personnel operates in order to prevent
After forget to lock and older lock loosens, which is provided with 2 sets of lock systems.First, compressing lock for common square hole;Second, being
Pin lock.On case lid, backstop is welded on bolt the tube chamber welds with base of pin lock, when using pin lock, by pulling and pushing bolt, is made
Backstop blocks limit or rotation release, to realize locking or unlocking function.Since bolt protrudes case lid, is removing case lid and putting
When setting case lid, there are the risks that bolt and ground collide with, and bolt is caused to deform.And it due to pedestal and case lid, backstop and inserts
The connection type of pin is welding, increases the difficulty of subsequent replacement bolt, therefore, a kind of detachable bolt locking device will
Possess good market prospects.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of detachable pin lock
Device, it is easy to use, save a large amount of cost.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model provides a kind of detachable bolt locking device, including bolt, and described bolt one end is connected with backstop,
The backstop side is provided with limited block, and the limited block side is provided with pedestal, and the chassis interior is provided with spring, described
Chassis outer side is provided with case lid, and the case lid surface is provided with plate, and the case lid is mounted on cabinet, and the tank surface is set
There is plate.
As a kind of optimal technical scheme of the utility model, the bolt is consolidated by the pedestal, the plate
It is fixed.
The utility model beneficial effect achieved is: the utility model has the advantages of simple structure, cheap, and practicability
By force, bolt is interspersed in the circular hole that pedestal both ends are opened, and can protect normally pulling and pushing for bolt, and backstop uses elastic cylindrical pin, installation
In the through-hole of bolt, limited block is for positioning backstop, the support that backstop passes through spring, it is ensured that it is stuck on limited block, from
And realize the switching function of lock, pin lock is welded on case lid, and bolt is inserted into the aperture of plate, thus realize the function of lock,
Simultaneously rotating latch is drawn outside when unlock, backstop is stuck on limited block, and bolt is detached from the circular hole of plate, then realizes unlocking function;
Locking process: backstop is detached from limited block by convolution bolt, and bolt is inserted into the circular hole of plate, lock function is realized, by cleverly setting
Meter, is optimized for detachable structure for pin lock, solves the problems, such as that replacement bolt is difficult, improves the working efficiency of device, save
About a large amount of cost, it is easy to use, there are good economic benefit and a social benefit, is suitble to promote the use of.

Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figure 1, the utility model provides a kind of detachable bolt locking device, including bolt 1, it is described
1 one end of bolt is connected with backstop 2, and 2 side of backstop is provided with limited block 3, and 3 side of limited block is provided with pedestal 4, institute
It states pedestal 4 and is internally provided with spring 5, case lid 6 is provided on the outside of the pedestal 4,6 surface of case lid is provided with plate 7, described
Case lid 6 is mounted on cabinet 8, and 8 surface of cabinet is equipped with plate 7.
In order to make this kind of detachable bolt locking device, easy to use, work efficiency is high, and the bolt 1 passes through the bottom
Seat 4, the plate 7 are fixed.
When the utility model is used, bolt 1 is interspersed in the circular hole that 4 both ends of pedestal are opened, the normal pumping of bolt 1 can be protected
It inserts, backstop 2 uses elastic cylindrical pin, is mounted in the through-hole of bolt 1, and for limited block 3 for positioning backstop 2, backstop 2 passes through spring
5 support, it is ensured that be stuck on limited block 3, to realize the switching function of lock, the lock of bolt 1 is welded on case lid 6, bolt 1
Be inserted into the aperture of plate 7, to realize the function of lock, when unlock outside draw and rotating latch 1, backstop 2 is stuck in limited block 3
On, bolt 1 is detached from the circular hole of plate 7, then realizes unlocking function;Locking process: backstop is detached from limited block by convolution bolt 1
3, bolt 1 is inserted into the circular hole of plate 7, realizes lock function.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
