Description
Technical field
The utility model relates to a kind of lockset, especially about a kind of electromagnetic lock that uses on high-tension switch cabinet cabinet door.
Background technology
Indoor electromagnetic lock is in order to prevent other people maloperation high-tension apparatus switch, it comprises that generally housing, panel, lock fasten, lock and fasten spring, block, handle, button, coil, moving iron core, travel switch, snap close and support, block and lock are fastened the lock that spring is contained in enclosure interior and are fixed, be installed in moving iron core and block coupling in the coil, coil reaches control lock by the moving iron core of adhesive and fastens mobile purpose.Panel is provided with handle and snap close, and snap close is fastened with lock by connecting rod and linked to each other.During use, the bar of dialling on handle is stirred, and handles the pulling snap close again and lock is fastened be in normally open.But it is excessive that this kind electromagnetic lock has volume, reaches the shortcoming that is not complementary with whole nation unified standard high-tension switch cabinet cabinet door bore size, need take lock body and panel could install apart during installation, and it is unreliable often to open performance.
At above-mentioned shortcoming, people have designed another kind of indoor electromagnetic lock, as Chinese patent ZL00206274.7 number, utility model name be called " indoor electromagnetic lock ", date of declaration is disclosed by the patent in February 7 calendar year 2001, this electromagnetic lock is provided with respectively with handle is connected with block in enclosure interior and dials plate, and often opens part what the enclosure interior setting had an elasticity boss.Yet there is following shortcoming in this kind design: indoor electromagnetic lock causes block to swing along locking bar because block does not have the location, and in the situation of no working power, block also can break away from moving iron core sometimes, causes electromagnetic lock also can open.
The utility model content
The purpose of this utility model is to provide a kind of reliability height, electromagnetic lock that anti-error performance is strong.
The purpose of this utility model is achieved in that this electromagnetic lock comprises housing, electromagnetic coil, moving iron core, handle, dials plate, locking bar elastic component and latching member, dial the plate two ends and connect handle and latching member respectively, locking bar elastic component and latching member are installed on the locking bar, moving iron core is installed in the electromagnetic coil and with latching member and mates, enclosure interior is provided with two guide rails with difference in height, form mobile space between two guide rails, place in this mobile space to the small part latching member and also can on guide rail, move.
Described latching member places the part in the mobile space to be provided with and first keeper of guide rail and the connector of variable height, and this first keeper is supported on the connector of this variable height and can slides on guide rail.
Corresponding first keeper of described guide rail is provided with second keeper, and this first keeper can be positioned on second keeper.
Described keeper has two, and it is supported on the two ends on the short transverse of connector respectively, and this two keeper moves on the guide rail of correspondence respectively.
Compared with prior art, the utlity model has following advantage: by the setting of two guide rails and keeper, make latching member can be in mobile space move left and right, played the function of guiding and location, thereby can prevent that the electromagnetic lock accident from opening, improve the reliability and the anti-error performance of electromagnetic lock.
Description of drawings
Fig. 1 is the structural representation of the utility model electromagnetic lock.
Fig. 2 is the structural representation of another direction of the utility model electromagnetic lock.
The specific embodiment
See also Fig. 1 and Fig. 2, the utility model electromagnetic lock comprises panel body, housing 2, locking bar 17, latching member 15, locking bar elastic component 12, dials plate 5, handle 7, electromagnetic coil 3, moving iron core 16, travel switch button 8 and travel switch 4.Panel body comprises untouchable plate 9 and is installed in the face frame 1 of its periphery.Housing 2 is the hollow setting, and it is fixedly mounted on panel body one side.
The inside of housing 2 also is provided with two guide rails 13 with certain altitude difference, be formed with mobile space 134 between this two guide rail 13, each guide rail 13 includes from left to right first guide rail 131, connecting portion 132 and second guide rail 133 of one connection successively, has difference in height between the top surface of this first, second guide rail 131,133, connecting portion 132 oblique extensions and have certain gradient, thus the spacing on surface of the connecting portion 132 of two guide rails 13 is reduced on direction from left to right gradually.All recessedly on two second guide rails 133 be formed with locating slot 14, adopt arc transition between this locating slot 14 and second guide rail 133.In the mobile space 134 of the part of latching member 15 between two guide rails 13, locking bar 17 is installed in latching member 15 and is positioned on mobile space 134 part outward.Latching member 15 is positioned at the part of mobile space 134 to offering installing hole 150 by guide rail 13, these installing hole 150 in the vertical directions run through latching member 15 and are eccentric setting with locking bar 17, be equipped with extending in the installing hole 150 and the connector 11 that shortens and being fixedly connected on respectively on this connector 11, the keeper 10 at following two ends, this two keeper 10 all stretches out latching member 15 external surface certain-lengths and can slide on the guide rail 13 of correspondence, the spacing of two keepers 10 is increased or reduce by elongating or shortening of connector 11, move thereby keeper 10 can be distinguished on two guide rails 13 of gap variable throughout.The left side of first guide rail 131 also can be provided with the 3rd guide rail 135, forms the stage portion 136 of vertical configuration between this first, the 3rd guide rail 131,135.In the present embodiment, connector 11 is a stage clip, keeper 10 for ball when reducing to slide and the frictional force between the guide rail 13.Above-mentioned keeper and locating slot can be called first keeper and second keeper, and in the moving process of latching member, first keeper can be positioned on second keeper.In addition, can make also wherein that positioning piece is fixed on the latching member, and another keeper is supported on the stage clip; Perhaps, only establish a keeper that is supported on the Flexible Connector, thereby an external surface of this keeper and latching member is moved on corresponding guide rail respectively.
