Description

Electromagnetic lock unlocking device

Technical Field

The utility model relates to the field of steaming, baking and sterilizing electric appliances, in particular to an electromagnetic lock unlocking device.

Background

Electric appliances such as an electric steam box, a steam oven and a steam baking disinfection box of an embedded cabinet or an integrated kitchen are high in internal temperature during working, and in order to guarantee safety, a door is locked through an electromagnetic lock in a working state, so that an infant can be prevented from being opened easily, or the infant can be prevented from being opened to scald an operator during working.

However, the electromagnetic lock may fail, or the lock hook of the electromagnetic lock is out of position, or the matched plastic lock hook is locked abnormally, or the return spring of the electromagnetic lock falls off, so that the door body cannot be opened. At this time, the electromagnetic lock needs to be corrected by manual disassembly.

The existing steaming, baking and sterilizing electric appliance takes appearance factors into consideration during manufacturing, and is generally provided with an installation screw of an embedded box body, and the installation screw is hidden at the side surface or inside of a cavity behind a door body, so that the installation screw cannot be detached and even cannot be disassembled without opening the door body, and the unique door opening mode can only be forcibly opened, and the uncontrollable property of the door opening method can possibly cause irreversible damage to the box body and even cause immeasurable damage to a matched cabinet or an integrated stove shell.

Therefore, the present inventors have further studied and developed an electromagnetic lock opener, and the present invention has been made based on the above.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electromagnetic lock ware of unlocking can unblank when the electromagnetic lock became invalid.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the utility model provides an electromagnetic lock ware of unlocking, sets up on the electromagnetic lock, includes link mechanism, link mechanism's tip is located the gap between the control panel of electrical apparatus and the door body, and link mechanism's end tail is located electromagnetic lock latch hook one side, and the tip that promotes link mechanism drives link mechanism's end tail to stir the electromagnetic lock latch hook and break away from the hasp.

Through install one in the crack gap of steam ager, oven, disinfect box with electromagnetic lock complex unlocking ware, can be under the condition of not destroying electrical apparatus box and the door body promptly, through the flat object link mechanism tip of contradicting, stir the unlocking ware through promoting link mechanism and unblank, and this kind of structure even touched under the condition of not using tools, also can be because propulsive distance is not enough and can't open the electromagnetic lock.

Further, link mechanism sets up in the casing, the casing outside is provided with a mounting panel, mounting panel and electromagnetic lock core phase-match, the ware of locktaking out is fixed by the electromagnetic lock core through the mounting panel.

Further, link mechanism includes push rod, buffer spring, driving lever, and the buffer spring both ends are connected with push rod and driving lever respectively, and the push rod transmits thrust as link mechanism's tip, and buffer spring transmits thrust to the driving lever, and the electromagnetic lock latch hook is stirred to the driving lever.

The effect of buffer spring firstly can prevent that the maloperation from opening the electromagnetic lock, and buffer spring can only transmit thrust to the driving lever under lasting exerting pressure, secondly can carry out link mechanism's reseing, with the driving lever pull-back and reset the push rod simultaneously after removing external force.

Further, link mechanism sets up in the casing, and the casing border has seted up first spout, the push rod passes from first spout, and the both ends of push rod are located the inside and outside both sides of casing respectively, and the displacement of push rod is restricted by first spout.

The first sliding groove can prevent the end of the thrust rod from being excessively stressed, so that the whole connecting rod mechanism is damaged.

Furthermore, the driving lever pin joint is in the casing, and the tip that driving lever and buffer spring are connected is arranged in the second spout of side, and the other end of driving lever links with the electromagnetic lock latch hook through setting up a driving medium that wears out the casing.

The second sliding groove is used for limiting the back-and-forth movement of the shifting rod to exceed the required amplitude, and the lock catch is prevented from being damaged.

After the scheme is adopted, compared with the prior art, the utility model, have following advantage:

the electromagnetic lock has the advantages that the structure is simple, the size is small, the electromagnetic lock can be directly installed and fixed on the electromagnetic lock, the normal work of the electromagnetic lock is not influenced, and the head of the push rod is pushed from a gap between the control panel glass and the door body only by using flat plate-shaped articles (such as a steel plate ruler, a fruit knife and the like), so that a linkage driving lever is generated, and the lock can be easily opened; in appearance, the head of the push rod is only slightly exposed outside the whole machine, so that the appearance of the whole machine is hardly influenced.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in the figure, an electromagnetic lock unlocking device comprises a shell 1, a push rod 2, a buffer spring 3 and a shifting rod 4, wherein the shell 1 is fixed beside an electromagnetic lock cylinder 8 through a mounting plate 11 arranged on the outer side, and the shape of one side edge of the mounting plate 11 is matched with the radian of the electromagnetic lock cylinder 8.

The shell 1 is internally provided with a buffer spring 3, a push rod 2 and a deflector rod 4, two ends of the buffer spring 3 are respectively connected with the push rod 2 and the deflector rod 4, the deflector rod 4 is pivoted in the shell 1, the pivoting point is close to the buffer spring 3, the end part of the deflector rod 4 connected with the buffer spring 3 is positioned in a second chute 6 at the side edge, and the other end of the deflector rod 4 is linked with an electromagnetic lock hook 7 by arranging a transmission piece 41 penetrating out of the shell 1; the first chute 5 has been seted up to casing 1 border, and push rod 2 passes from first chute 5, and the both ends of push rod 2 are located casing 1 inside and outside both sides respectively, and the displacement of push rod 2 is restricted by first chute 5.
