Abstract
The utility model relates to a spacing device for an electric door rolling machine, comprising a casing, a travel switch fixed on the basal plane of the casing, a gear connected with a transmission mechanism and a screw rod connected with a gear shaft, wherein, the travel switch is arranged on one side of the screw rod; a slotted round nut is also arranged on the screw rod; the other side of the screw rod is provided with an inserting piece; a slotted hole is arranged on the inserting piece and fixedly connected with the basal plane of the casing through a screw nail. The utility model has the advantages of simple structure, convenient operation and adjustment and reliable running.
Description
The utility model relates to a kind of stop, especially a kind of stop that is used to regulate the electric roll-up door mechanism of rolling door height.
When electric roll-up door mechanism was elevated to preset height with rolling door, stop promptly sent the signal of telecommunication, executing agency action, thereby with door locked on a certain height.When the transmission mechanism of door-rolling machine moved, the screw rod in the stop rotated, thereby made the positioning devices axially-movable on the screw rod, touched travel switch, sent the signal of telecommunication.Therefore in order to ensure stop energy operate as normal, the positioning devices on the screw rod can not produce and rotatablely move.If will regulate the height of rolling door, then regulate the position of positioning devices on screw rod and get final product, therefore, the positioning devices on the screw rod should be regulated.The stop of existing electric roll-up door mechanism often adopts slide block groove type structure, and slide block is embedded in the groove can make linear slide, and the nut plug forms one with slide block in the circular hole of slide block, and the spatial dimension of therefore stirring nut is too little, and operation is regulated inconvenient.Recently on the market a kind of Spring Card chip stop has appearred also, it mainly is made of slotted round nut, card slide bolt, positioning bolt, spring and extension spring etc., the rotation of its slotted round nut is that the effect by the card spring is limited, so its complex structure, the card slide bolt is easily blocked during use, and single positioning bolt can not fully be located, and makes stop be in failure state easily.
The purpose of this utility model provides a kind of simple in structure, and the operation debugging is convenient, and reliable electric roll-up door mechanism stop.
Realize that the utility model purpose technical scheme is: the electric roll-up door mechanism stop, include housing, be fixed on two travel switches on the housing baseplane, the gear that is connected with transmission mechanism, the screw rod that is connected with gear shaft, two travel switches are arranged on a side of screw rod, it is characterized in that: slotted round nut also is housed on the screw rod, and the opposite side of screw rod is provided with inserted sheet; Grooved hole on the inserted sheet, and fixedly connected with the housing baseplane by screw.
Because feature of the present utility model only is slotted round nut, inserted sheet, the fixing screw of inserted sheet, so simple in structure, has reduced cost of production; When regulating the position of slotted round nut, unclamp screw and just can regulate, the operation debugging easily; Inserted sheet fills a part location through two screws, is difficult for landing, and is reliable.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Structural representation when Fig. 1 is the utility model work;
Fig. 2 is the structural representation of the utility model inserted sheet 7;
Fig. 3 is the front view of slotted round nut 3-1 of the present utility model, 3-2;
Fig. 4 is the vertical view of the utility model slotted round nut 3-1,3-2.
As shown in Figure 1, the utility model includes housing 1, is fixed on travel switch 2-1,2-2 on housing 1 baseplane, the gear 5 that is connected with transmission mechanism, with 5 screw rods that are connected 4 of gear, travel switch 2-1,2-2 are arranged on a side of screw rod 4, slotted round nut 3-1, the 3-2 of the 2-1, the 2-2 that are used for touching respectively travel switch also are housed on the screw rod 4, and concrete structure is seen Fig. 3, Fig. 4.The opposite side of screw rod 4 prevent from when the stop operate as normal also is housed the to slot inserted sheet 7 of round spiral shell 3-1,3-2 rotation; Grooved hole 7-1,7-2 on the inserted sheet 7 are fixedlyed connected with housing 1 baseplane by screw 6-1,6-2.Two screws can fill inserted sheet 7 a part location.During operation, inserted sheet 7 is difficult for breaking away from, and inserted sheet 7 is embedded in the slotted eye of slotted round nut 3-1,3-2, and slotted round nut 3-1,3-2 can only be moved axially, and has reached reliable purpose of the present utility model.Jack 7-1,7-2 on the described inserted sheet 7 are the L type, see Fig. 2, and it can prevent that inserted sheet 7 from falling, and has improved the reliability of stop, and the utility model is simple in structure, and the operation debugging is more convenient.
Before the stop work, a straight flange of inserted sheet 7 is inserted and is embedded in the groove of slotted round nut 3-1,3-2, and screw 6-1,6-2 are fixed on inserted sheet 7 on the baseplane of housing 1, connects power supply, the transmission mechanism running, gear rotates, and drives screw rod 4 rotations, and slotted round nut 3-1,3-2 do by to displacement, up to touching travel switch 2-1 or 2-2, cut off the electricity supply, electric roll-up door mechanism is promptly out of service, thereby rolling door is fixed on a certain position.
When needs are regulated the setting height of rolling door, only need regulate slotted round nut 3-1, the 3-2 position on screw rod, unclamp screw 6-1,6-2, inserted sheet 7 and promptly break away from slotted round nut 3-1,3-2 automatically, so slotted round nut 3-1,3-2 are free to rotate, the operation debugging is very convenient.
