Abstract
The utility model discloses a guide rail traction type door opening machine with the function of mechanically locking at any position, which includes a chain (1), a chain connector (2) and a clutch trolley (3); the clutch trolley (3) is provided with a slide block (4) which can move horizontally in the clutch trolley (3) and be inserted into the chain connector (2), and a slide block booster (5). The machine is characterized in that the slide block (4) is 2 to 10mm wide and 2 to 8mm thick. Because the slide block is designed with a dimension by which the slide block can be inserted into the chain joint, so when door is closed manually upon power-off, the slide block booster inserts the slide block into the chain joint corresponding to the position of the slide block, so that the door is locked mechanically, which keeps a garage safe. The fork-shaped design of the slide block improves the strength of the slide block, and a positioning pin on the slide block booster makes sure the slide block works stably, so the utility model is especially applicable in the environments where power-off occurs frequently.
Description
Technical field:
The utility model relates to a kind of door lifter that has guide rail traction to utilize chain transmission mode, and especially a kind of have lock a door a towed door lifter of guide rail of function of machinery at an arbitrary position.
Background technology:
At present, the structure of widely used garage door door lifter all is made up of motor and control section and traction guide rail, and concrete structure is to be connected to gear with motor output shaft, with gears engaged chain is arranged, and is connected to chain link remover in the middle of the chain; And comprise the clutch dolly that is fixedly mounted on the door, be provided with the slide block and the laterally mobile slide block propeller of control slide block that can in the clutch dolly, laterally move and can insert in the chain link remover in the clutch dolly.Generally be that slide block is inserted in the chain link remover, make chain drive by motor driven gear, chain link remover then moves door by the slide block that joins with it, by the forward or reverse of control motor, the then purpose that can reach electric open-door or close the door.Lock a door as need, only need the control motor to shut down and get final product.If have a power failure suddenly, then can leave chain link remover by slide block propeller control slide block, can realize opening Door by Hand or closing the door.And since existing slide block be generally the square that the length of side is 11.3mm, all greater than the slit of chain, can only insert in the hole of chain link remover, therefore, open Door by Hand or close the dislocation that goalkeeper makes chain link remover and slide block, thereby can't realize that machinery locks a door, can't guarantee the safety in garage.
Summary of the invention:
The purpose of this utility model is in order to solve the existing problem that can't mechanical lock a door in the prior art, a kind of towed door lifter of guide rail of the mechanical function of locking a door at an arbitrary position that has to be provided.
Technical solution of the present utility model is: a kind of have at an arbitrary position lock a door a towed door lifter of guide rail of function of machinery, comprise chain 1, chain link remover 2 and clutch dolly 3, in clutch dolly 3, be provided with the slide block 4 and the slide block propeller 5 that can in clutch dolly 3, laterally move and can insert in the chain link remover 2, wide 2～the 10mm of described slide block 4, thick is 2～8mm.
Described slide block 4 is two wide 2～10mm of being, thick is the fork-shaped of the bar formation of 2～8mm.
Described chain link remover 2 for fork-shaped slide block 4 double-pore structure that is complementary.
On slide block propeller 5, also can be provided with groove 6, be provided with alignment pin 7 in the groove 6.
One end of described alignment pin 7 can be placed in the groove 9 set on the clutch dolly lid 8.
The utility model is compared with prior art, since slide block be designed and sized to the size that can insert the chain slit, can have a power failure manually at closing time, by the slide block propeller with slide block insert with corresponding chain slit, slide position among, realization machinery is locked a door, and has guaranteed the safety in garage.The intensity of fork-shaped design enhancing slide block of slide block; The setting of the alignment pin on the slide block propeller then can guarantee the stability of slide block work; Be adapted to especially in the environment that often has a power failure, use.

Structural representation when Fig. 2 is the utility model embodiment state 2.
Structural representation when Fig. 3 is the utility model embodiment state 3.
Fig. 4 is the structural representation of the little car bonnet of the utility model embodiment state clutch.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, shown in Figure 4, the utility model embodiment comprises chain 1, chain link remover 2 and clutch dolly 3, in clutch dolly 3, be provided with the slide block 4 and the slide block propeller 5 that can in clutch dolly 3, laterally move and can insert in the chain link remover 2, slide block 4 is of a size of the size that can insert chain 1 slit, wide is 2～10mm, and thick is 2～8mm.In order to strengthen the intensity of slide block 4, slide block 4 also is two wide 2～10mm of being, thick is the fork-shaped of the bar formation of 2～8mm, and 2 of chain link removers are the double-pore structure that is complementary with fork-shaped slide block 4.Also can be provided with groove 6 on slide block propeller 5, be provided with alignment pin 7 in the groove 6, an end of alignment pin 7 can place in the groove 9 set on clutch dolly lid 8 shown in Figure 4, and also movable being connected on the clutch dolly 3 is to guarantee the job stability of slide block 4.
The course of work is as follows: under normal (having) situation, slide block 4 is inserted in the chain link remover 2, makes chain 1 transmission by motor driven gear, and 2 of chain link removers move door by the slide block 4 that joins with it, by the forward or reverse of control motor, the purpose that reaches electric open-door or close the door.Lock a door as need, only need the control motor to shut down and get final product, at this moment, alignment pin 7 places the peak of groove 6, catches hold of slide block propeller 5, prevents to move on it, avoids in the slide block 4 indentation clutch dollies 3.When unexpected power failure, can be as shown in Figure 2: on move slide block propeller 4 control slide block indentation clutch dollies 3, leave chain link remover 2, then can realize opening Door by Hand or closing the door, this moment, alignment pin 7 placed the minimum point of groove 6, prop up slide block propeller 5, prevent that it from moving down, avoid slide block 4 to stretch out outside the clutch dolly 3.In the time of need locking a door, can be as shown in Figure 3: again slide block propeller 5 is moved down, slide block 4 is stretched out from clutch dolly 3, insert among the slit of the chain 1 corresponding, use external force also door can't be lifted, realized that the machinery under power down mode is locked a door with it.When sending a telegram here once more, then slide block 3 can be moved to chain link remover 2 places, insert in the chain link remover 2 operate as normal again.
