Abstract

The utility model discloses an interactive linkage device, comprising a support seat arranged between an outer door frame and an inner door frame, a rocker hinged on one end of the outer door frame near the support seat, a pulling rod also arranged on the rocker which the other end is matched with a concave hole on a lock tongue of the inner door, a baffle sheathed on the pulling rod between the inner door frame and the outer door frame is fixed on a standing plate, a spring is sheathed on the pulling rod, with one end fixed on the baffle and the other end fixed on the pulling rod. Since the device controls the pulling rod on the rocker by the effect of the lock tongue of the outer door to the rocker, and controls the open and close of the inner door by the pulling rod, when entering into the outer door, the outer door must be locked, otherwise the inner door cannot be opened with a key if the outer door is open. The structure can effectively play a role of protection for the safety of a bank by extending an entry time of a robber into the bank so that bank staffs have sufficient time to deal with the situation, thus, prevent state properties from damage and personnel from injury.

Description

A kind of interactive interlock

Technical field

The utility model belongs to check mechanism, relates in particular to a kind of interactive interlock that is used for security door.

Background technology

The savings department of a bank is the place that people often come in and go out, because its particularity all is equipped with two fan security doors in the savings bank of each bank, purpose is to prevent that the bandit from swarming into Administrative Area suddenly when bank clerk passes in and out.Existing security door structure and common security door do not have any difference, when opening first sect, also can open second sect during use, easily like this create the chance rush in bank, cause certain loss, also can cause personal injury the staff of bank to national wealth to the bandit.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of a kind of interactive interlock that can control two fan door switch effectively is provided.

The utility model is achieved through the following technical solutions: a kind of interactive interlock, comprise the bearing that is installed between exterior door frame and the interior doorframe, be hinged with rocking arm near an end of exterior door frame on the bearing; pull bar also is housed on the rocking arm; the other end of pull bar matches with shrinkage pool on the inside door dead bolt; be with baffle plate on the pull bar between interior doorframe and the exterior door frame; baffle plate is fixed on the riser between interior doorframe and the exterior door frame; be with spring on the pull bar; an end of spring is fixed on the baffle plate, and the other end is packed on the pull bar.

Be flexible connection between described rocking arm and the pull bar.

Be positioned on the pull bar of doorframe and install a block, the length of block is less than the distance of the interior span Inner door lock tongue of interior doorframe, and described spring is between block and baffle plate, and the two ends of spring are packed in respectively on block and the baffle plate.

Described spring is between the inwall of block and interior doorframe.

After adopting above-mentioned technical scheme and since this device be by the external door dead bolt to rocking arm be used for controlling pull bar on the rocking arm, and the switch by pull bar control inside door, this structure can play effective protective effect to the safety of bank.If the bandit has rushed in external door; when entering external door, external door must be pinned; promptly use key also can't open inside door as not locking external door; therefore can prolong the time that the bandit enters bank; is provided to the staff of bank the sufficient reply time, therefore protected national wealth and staff to escape injury.Even the bandit enters bank, it also is quite difficult getting away again.

Fig. 3 figure is the structural representation of embodiment 3.

The specific embodiment

Embodiment 1: as shown in Figure 1, between exterior door frame 9 and interior doorframe 14 bearing 6 is installed, the end near exterior door frame 9 on the bearing 6 is hinged with rocking arm 7, and pull bar 3 also is housed on the rocking arm 7, and is flexible connection between rocking arm 7 and the pull bar 3.The other end of pull bar 3 matches with shrinkage pool 2 on the inside door dead bolt 1.Be with baffle plate 5 on the pull bar 3 between interior doorframe 14 and the exterior door frame 9, on the riser 15 in baffle plate 5 is fixed between doorframe 14 and the exterior door frame 9, be with spring 4 on the pull bar 3, an end of spring 4 is fixed on the baffle plate 5, and the other end is fixed on the pull bar 3.

Embodiment 2: as shown in Figure 2, the structure of the structure of present embodiment and embodiment 1 is basic identical, its difference is to be positioned on the pull bar 3 of doorframe 14 to install a block 16, the length of block 16 is less than the distance of the interior span Inner door lock tongue 1 of interior doorframe 14, spring 4 is between block 16 and baffle plate 5, and the two ends of spring 4 are packed in respectively on block 16 and the baffle plate 5.

Embodiment 3: as shown in Figure 3, the structure of the structure of present embodiment and embodiment 2 is basic identical, and its difference is that described spring 4 is between the inwall of block 16 and interior doorframe 14.

External door 10 and inside door 12 all are in closed condition before using, and external door dead bolt 8 is with rocking arm 7 jack-up, and rocking arm 7 makes pull bar 3 move towards the direction of external door 10 simultaneously, and the other end of pull bar 3 then breaks away from the shrinkage pool 2 on the inside door dead bolt 1, and spring 4 is in confined state at this moment.Must advance man-hour from outer 10 as the people, available key is opened external door 10 earlier, external door dead bolt 8 breaks away from rocking arm 7, pull bar 3 moves to the direction of inside door 12 under the effect of spring 4, the other end of pull bar 3 just in time places in the shrinkage pool 2 on the inside door dead bolt 1, external door 10 is locked after entering between external door 10 and the inside door 12, this moment, this device was in the state when initial again, and the just available key of inside door 12 is opened the Administrative Area that enters bank.

Handle 13 when going out on the rotatable inside door 12 is opened inside door 12, rotates handle 11 on the external door 10 again and opens external door 10 and get final product.
