Abstract
The utility model relates to a safety protection lock of an equipment compartment apron board, which adopts a light tensioning lock to be optimized structurally, resolves the problem that an apron board valve is easy to become invalid, accordingly effectively lightens weight and strengthens safety protection measures. The safety protection lock realizes stable and reliable connection, simplifies locking and unlocking operation processes, and simultaneously increases connection stability of a locking mechanism so as to effectively prevent valve connection from becoming invalid. The safety protection lock comprises a locking mechanism and an operating mechanism, and the locking mechanism is mounted on an apron board mounting panel and is connected with the operating mechanism via a support. Compared with the prior art, the safety protection lock is characterized in that the operating mechanism is provided with a lock body, a lock cylinder is rotationally connected into the lock body, and the tail end of the lock cylinder is connected with a slip knot. The locking mechanism is provided with a shell, a lock bolt, a shifting fork and a compression spring are successively connected into the shell from outside to inside, and the compression spring of the locking mechanism is sleeved at the end of the slip knot of the operating mechanism.
Description
Technical field
The utility model is the safeguard protection lock that uses at railway vehicle device cabin skirtboard, belongs to mechanical manufacturing field.
Background technology:
Follow developing rapidly of domestic track traffic, correspondingly the installation design for equipment under car body and the car has proposed higher technical standard with use.The speed per hour of existing rail vehicle has reached more than 380 kilometers/hour, for improving travel speed and traffic safety further, requires equipment compartment skirtboard fully locking, the accident that can not meet accident and open.
The equipment compartment of vehicle is the integral sealing cabin body that is formed by connecting by equipment compartment skeleton and skirtboard, base plate or end plate, and so that relevant device and parts to be installed below car body, skirtboard can be opened or the locking inefficacy anything but in the vehicle ' process.
The valve lock construction that the equipment compartment skirtboard uses comparatively simply, is not provided with effectively anti-inefficacy remedial measure.When rail vehicle when running at high speed, exist the problem of antidetonation, the anti-loose aberrations in property of connecting portion on the one hand, be easy to cause skirtboard unexpectedly to open; On the other hand, skirtboard valve lock connected mode is comparatively loaded down with trivial details, is unfavorable for quick inspection operation.
The utility model content
Equipment compartment skirtboard safeguard protection described in the utility model lock is to solve above-mentioned prior art defective and the Strain lock structure optimization of taking lightweight, at the skirtboard valve Problem of Failure takes place easily to make improvement, in the hope of effectively reducing the weight and the intensified safety precautionary measures.
Purpose of design of the present utility model is, realizes reliablely and stablely connecting, and simplifies locking and opening operation flow process.Improve the connective stability of locking mechanism simultaneously, lost efficacy to prevent that effectively valve from connecting.
For realizing above-mentioned purpose of design, described equipment compartment skirtboard safeguard protection lock mainly includes:
Locking mechanism and operating mechanism,
Locking mechanism is installed on the skirtboard installation panel, and locking mechanism connects operating mechanism by support.The difference with the prior art part is,
Described operating mechanism is provided with lock body, the lock body inner rotation be connected with lock core, the terminal slip-knot that connects of lock core.
Described locking mechanism is provided with housing, in turn is connected with dead bolt, shift fork and compression spring from outside to inside in enclosure interior;
The compression spring of locking mechanism is socketed in the slip-knot end of operating mechanism.
As above-mentioned basic scheme feature, safeguard protection lock simple in structure and help realizing light-weight design.When solving skirtboard valve safety problem, the flexible operating mechanism of employing closes the mode of occupation that locking mechanism combines with hitting.
For improve with the skirtboard valve between reliable and stable the connection, the corrective measure that can take is that lock body is installed on support by sheathed nut and bullet pad.
As mentioned above, the advantage that has of the utility model equipment compartment skirtboard safeguard protection lockset is:
1, takes the Strain lock structure optimization of lightweight, reduce weight effectively;
2, intensified safety is taken precautions against, and realizes reliablely and stablely being connected with the skirtboard valve, prevents that effectively valve from connecting inefficacy;
3, simplify locking and opening operation flow process, the convenience when improving maintenance.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme of installation of described safeguard protection lock;
Fig. 2 is the structural representation of locking mechanism;
As depicted in figs. 1 and 2, skirtboard installation panel 1, locking mechanism 2, support 3, operating mechanism 4, nut 5, bullet pad 6;
Lock body 41, lock core 42, slip-knot 43.
The specific embodiment
As depicted in figs. 1 and 2, described equipment compartment skirtboard safeguard protection lock includes locking mechanism 2 and operating mechanism 4.Wherein,
The housing 21 of locking mechanism 2 is installed on the skirtboard installation panel 1, and locking mechanism 2 connects operating mechanism 4 by support 3.
The lock body 41 of operating mechanism 4 is installed on support 3 by sheathed nut 5 and bullet pad 6.
During unlatching, supporting key alignment lock core 42 is inserted lock bodies 41, left-handed or dextrorotation key is to spacing.
During locking, the skirtboard valve is pushed locked position, dead bolt 22 is locking voluntarily under the effect of compression spring 24.
