Technical field
The present invention relates to medical device industry, relate to the door lock of medical disinfecting cabinet, specifically a kind of safety door lock device.
Background technology
Domestic common disinfection cabinet safety door lock device does not mostly well reach safe effect at present, and the laws and regulations requirement safety door latch is when disinfection cabinet is worked, and door lock is no matter how carried out operation how and all door can't be opened by locked.The safety door latch of present domestic design can be opened door when disinfection cabinet is worked fully, and safeguard procedures just put up information warning and finish near manual and door handle, has serious potential safety hazard.External some design meets laws and regulations requirement, and design can be accomplished can't open the disinfection cabinet door lock when disinfection cabinet is worked, but external project organization complexity, manufacturing cost are bigger.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of safety door lock device is provided, this door latch structure is simple, reasonable, can guarantee disinfection cabinet when work, and door lock is locked fully.
According to technical scheme of the present invention: a kind of safety door lock device, it is characterized in that: comprise the door bolt perforation that is installed on the doorframe, be installed on the door linkage main body on the door, in the chute of door linkage main body middle part, slide and be provided with the door lock pin, in the door bolt perforation, offer slide opening corresponding to door lock pin place, described door lock pin tail end is fixedly connected with the door bolt guide peg, and door bolt guide peg middle part places in first chute that linkage body front part end face is offered, door bolt guide peg leading section places in second chute of door handle spill spin block, described door handle spill spin block rotates by the door handle turning cylinder and is arranged on the linkage body front part end face, and door handle is fixed on the door handle spill spin block by the door handle set bolt.
As a further improvement on the present invention, offer the 3rd chute at the rear portion of described door linkage main body, electromagnetism keeper one end slides and is arranged in described the 3rd chute, and the electromagnetism keeper other end is connected on the state detector.
As a further improvement on the present invention, the chute at door linkage main body middle part is connected in described the 3rd chute bottom.
As a further improvement on the present invention, the length of described first chute is bored a hole away from the distance between the end face of door near end face and the door bolt of doorframe greater than door linkage main body.
Technique effect of the present invention is: the present invention is simple in structure, safe and practical, and the electromagnetism keeper that uses among the present invention simultaneously makes door latch structure more safe and reliable; The door state detector that installs additional can be known a present located state at any time; Reasonable in design of the present invention is convenient to install and maintenance.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
In Fig. 1 ~ 6, comprise door handle 1, door handle turning cylinder 2, door handle set bolt 3, door handle spill spin block 4, door linkage main body 5, door lock pin 6, door bolt perforation 7, door bolt guide peg 8, electromagnetism keeper 9, door state detector 10, first chute 11, second chute 12, the 3rd chute 13 etc.
Shown in Fig. 1 ~ 6, the present invention is a kind of safety door lock device, comprise the door bolt perforation 7 that is installed on the doorframe, be installed on the door linkage main body 5 on the door, in door linkage main body 5 middle part chutes, slide and be provided with door lock pin 6, in door bolt perforation 7, offer slide opening corresponding to door lock pin 6 places, described door lock pin 6 tail ends are fixedly connected with door bolt guide peg 8, and door bolt guide peg 8 middle parts place in first chute 11 that linkage main body 5 front end face offers, door bolt guide peg 8 leading sections place in second chute 12 of door handle spill spin block 4, described door handle spill spin block 4 rotates by door handle turning cylinder 2 and is arranged on linkage main body 5 front end face, and door handle 1 is fixed on the door handle spill spin block 4 by door handle set bolt 3.
Rear portion in described door linkage main body 5 offers the 3rd chute 13, and electromagnetism keeper 9 one ends slide and are arranged in described the 3rd chute 13, and electromagnetism keeper 9 other ends are connected on the state detector 10.
The chute at door linkage main body 5 middle parts is connected in described the 3rd chute 13 bottoms.
The length of described first chute 11 bores a hole 7 away from the distance between the end face of door greater than door linkage main body 5 near end face and the door bolt of doorframe.
The course of work of the present invention is as follows: opening door operation, see shown in Figure 6, start the power supply of electromagnetism keeper 9, under the effect of electromagnet, electromagnetism keeper 9 is upwards smoked, the microswitch that is connected a state detector 10 places this moment detects the information that door is opened, and information via handled convey to the user, the user obtains knowing that door lock is opened after this information, just carry out the following action of opening the door, door handle is rotated to the extreme higher position (as shown in Figure 4), door handle 1 drives the orbit rotation that door handle spill spin block 4 is pressed door bolt guide peg 8 in this process, because door bolt guide peg 8 and door lock pin 6 are fixed together, therefore door lock pin 6 is extracted out from door bolt perforation 7, and the keeper between this moment door beam and doorframe is opened, this moment with door handle 1 with Men Lakai.
Close door operation: door handle 1 is upwards lifted about 90 degree (as shown in Figure 4), the door beam near doorframe (as shown in Figure 5), is equipped with a state detector 10 between door beam and doorframe, whether monitoring door is near doorframe in real time.After door is close to, door handle 1 is rotated about 90 degree, in the door lock pin 6 insertion door bolt perforation 7 this moment, simultaneously electromagnetism keeper 9 is got back to electromagnetism keeper 9 insertion states (as shown in Figure 3) from drawing back state (as shown in Figure 6), thereby in the track of door lock pin 6 cause door handle 1 by locked and can't be lifted because electromagnetism keeper 9 is inserted into this moment, this just means that door is lockable, unless start electromagnet electromagnetism keeper 9 is drawn back, closed the structure of safety door latch (as shown in Figure 1) behind the door.
The present invention is simple in structure, safe and practical, and the electromagnetism keeper that uses among the present invention simultaneously makes door latch structure more safe and reliable; The door state detector that installs additional can be known a present located state at any time; Reasonable in design of the present invention is convenient to install and maintenance.
