Abstract
The utility model discloses a safety door anti-back door lock of an injection molding machine. The safety door anti-back door lock comprises a lock seat, wherein the lock seat is internally provided with a lock core; the lock core is in transmission connection with a handle. The safety door anti-back door lock is characterized in that the handle is in transmission connection with a lock catch mechanism; the lock seat is internally provided with a limiting mechanism which is corresponding to the lock core; the lock catch mechanism comprises two lock catches; the opposite end parts of the two lock catches are connected; one lock catch is in shaft joint with the lock seat; the lock catch which is in shaft joint with the lock seat is in transmission connection with the handle, and a return spring is arranged between the lock catch and the lock seat. According to the safety door anti-back door lock, the lock catches can be automatically buckled under the effect of guide inclined surfaces; meanwhile, by use of the pulling force of the return spring, the requirements on easiness in opening and reliability in closing are realized, and the safety door anti-back door lock is reasonable in design, high in practicability and convenient to popularize.
Description
Technical field
The utility model belongs to injection molding machine safety door field, specifically, relates to a kind of injection molding machine safety door anti-back door lock.
Background technology
In injection machine manufacturing process, only have when safety door and close, could normally produce, so how could allow safety door close? traditional way is, in the relevant position of door guide rail, one boss is set, or breach, with this, blocks the trolley of safety door, prevent that safety door from retreating, and then be opened.But this way exists very large hidden danger, this is because the height of boss design, or breach design dark, and when needs open the door, safety door is difficult to be opened; Short when boss design, or breach design is shallow, and safety door can be opened automatically due to the vibrations of machine, causes shutdown.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, provide a kind of reasonable in design, open easily, close reliable injection molding machine safety door anti-back door lock.
For addressing the above problem, the technical scheme that the utility model adopts is:
An injection molding machine safety door anti-back door lock, comprises lock, is provided with lock core in lock, and the lock core jug that is in transmission connection, is characterized in that: described handle is connected with latching device; In described lock, be provided with the position-limit mechanism corresponding with lock core.
Described latching device comprises two snap closes, and two snap close opposed ends connect, and one of them snap close axle is connected on lock; Axle is connected to snap close on the lock handle that is in transmission connection, and is provided with back-moving spring between this snap close and lock simultaneously.
On described snap close opposed end, be provided with guiding surface.
Described and lock core is the limited block being arranged on lock to the position-limit mechanism of use.
Owing to having adopted technique scheme, compared with prior art, snap close of the present utility model can be under the effect of guiding surface automatic buckling, utilize the pulling force of back-moving spring simultaneously, realized and opened easily, close reliable requirement, reasonable in design, practical, be convenient to promote.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of injection molding machine safety door anti-back door lock, comprises the lock 5 being arranged on safety door 6, is provided with lock core 2 in lock 5, lock core 2 jug 7 that is in transmission connection.Described handle 7 is connected with latching device, is provided with the position-limit mechanism corresponding with lock core 2 in lock.
In the present embodiment, described latching device comprises that 1, two snap close of two snap closes, 1 opposed end connects, and one of them snap close 1 is connected on lock 5 by turning cylinder 3.
Axle is connected to snap close on the lock handle 7 that is in transmission connection, and is provided with back-moving spring 8 between this snap close and lock simultaneously.
On described snap close 1 opposed end, be provided with guiding surface.2 pairs of described and lock cores with position-limit mechanism be the limited block 4 being arranged on lock.
Snap close of the present utility model can be under the effect of guiding surface automatic buckling, utilize the pulling force of back-moving spring simultaneously, realized and opened easily, close reliable requirement, reasonable in design, practical, be convenient to promote.
Above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit, although executing example with reference to previous examples has been described in detail the utility model, those of ordinary skill in the art is to be understood that, it is modified according to the technical scheme that can record aforementioned each embodiment, or its part technical characterictic is equal to replacement, and these modifications or replacement, do not make the essence of appropriate technical solution depart from spirit and the category of technical solutions of the utility model.
