Description
Technical field
It the utility model is related to field of mechanical technique, and in particular to a kind of safety lock mechanical elastic structure lock tongue.
Background technology
Numerically-controlled machine tool door safety lock, is the important safety device of numerically-controlled machine tool, it effectively ensures lathe operation
Reliability and security.And to lock its locking not firm for the machine safety of the prior art, and lock tongue is carried out in insertion lock body
During safety locking, lock tongue and lock body are entirely very stiff and demanding shock, without enough bufferings, cause safety lock rapid wear in use
It is bad, the problems such as service life is not long；Since safety lock is fragile, therefore its maintenance rate is high, adds after cost.
The content of the invention
To overcome drawbacks described above, the purpose of this utility model is to provide a kind of safety lock mechanical elastic Structural lock
Tongue.
The purpose of this utility model is achieved through the following technical solutions：
The utility model is a kind of safety lock mechanical elastic structure lock tongue, it is installed in door body, including：It is fixedly mounted
In the stake body in door body, the rear end of the mounting platform of the stake body is equipped with positioning plate, and the positioning plate is equipped with location hole,
Activity is equipped with screw rod in the location hole, and the front end of the screw rod is mutually fixed with the rear end of lock tongue, is worn on the outside of the screw rod
There is spring, and the front end of the spring and the rear end of the lock tongue abut against, the rear end of the spring is abutted against with the front end of the positioning plate；
The front portion of the mounting platform is provided with pressing plate, and the lock tongue is actively located in the space that the pressing plate is surrounded with mounting platform
On, the front end of the lock tongue is equipped with and the matched lock of closing piece.
Further, the area of the spiro rod rear end is more than the area of the location hole.
Further, the bottom of the mounting platform is equipped with the installing plate being connected with door body.
Further, the pressing plate is formed with lock tongue by stainless steel sheet metal component.
Safety lock mechanical elastic structure lock tongue described in the utility model produces when can buffer lock tongue insertion lock body
Impact, sliding is good, easily production and processing, service life length, significantly reduce after cost.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following preferred embodiments and attached drawing.
Fig. 1 is the overall structure figure of the utility model；
Fig. 2 is not locking the position relationship schematic diagram of state for the utility model；
Fig. 3 is position relationship schematic diagram of the utility model during locking；
Fig. 4 is locking the position relationship schematic diagram of state for the utility model；
Fig. 5 is the overall assembly relation schematic diagram of the utility model.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further described the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With new, it is not used to limit the utility model.
Please refer to Fig.1 to Fig. 5, the utility model is a kind of safety lock mechanical elastic structure lock tongue, it is installed on door body 7
On, including：The stake body being fixedly installed in door body 7, the rear end of the mounting platform 8 of the stake body is equipped with positioning plate 4, described
Positioning plate 4 is equipped with location hole, in the location hole activity be equipped with screw rod 5, the front end of the screw rod 5 and the rear end of lock tongue 1
Mutually fixed, the outside of screw rod 5 is equipped with spring 3, and the front end of the spring 3 and the rear end of the lock tongue 1 abut against, the spring 3
Rear end and the front end of the positioning plate 4 abut against；The front portion of the mounting platform 8 is provided with pressing plate 2, and 1 activity of lock tongue is worn
Surrounded spatially arranged on the pressing plate 2 and mounting platform 8, the front end of the lock tongue 1 is equipped with and the matched lock of closing piece.
Further, the area of 5 rear end of screw rod is more than the area of the location hole, avoids screw rod 5 from deviating from from location hole.
Further, the bottom of the mounting platform 8 is equipped with the installing plate 9 being connected with door body 7.
Further, the pressing plate 2 is formed with lock tongue 1 by stainless steel sheet metal component；Its is light-weight, and intensity is high, and sliding is good,
Beneficial to safety locking, scale of mass production performance is good, and easy processing easily produces, and cost is low.
The concrete operating principle of the utility model is：When the door body 7 is static, lock tongue 1 is not inserted into lock body 6, Liang Zhebao
Hold relatively independent state.Door body 7 is pulled to the right, and lock tongue 1 follows door body 7 to move right, until the lock insertion lock in lock tongue 1
After body 6, lock tongue 1 is impacted power and 7 direction of motion of door body on the contrary, 1 back-end compression spring 3 of lock tongue, and 5 stress of screw rod is to left movement
Pop-up, so as to buffer the impact that lock tongue 1 is inserted into lock body 6.The door body 7 closes in place, and lock insertion lock body 6 locks jail
Lean on, spring 3 is in non-urgent compressive state.
The utility model designs increase compression spring 3 in 1 rear end of lock tongue, when making the lock insertion lock body 6 in lock tongue 1
The impact buffering of generation is removed, and reduces safety lock damage, adds safety lock service life, is conducive to improve numerically-controlled machine tool
Security, and reduce after-sales service cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
