Abstract
The utility model relates to the technical field of rolling door operators, in particular to a rolling door operator travel limiter. Compared with the prior art, the rolling door operator travel limiter comprises a limit casing. Fixed connecting plates are arranged on two sides of the limit casing; an output connecting shaft penetrates through the fixed connecting plates of the limit casing transversely; a portion, between the fixed connecting plates on two sides of the limit casing, of the output connecting shaft, is provided with a rotary thread; two limit rollers are arranged on the rotary thread, and a certain distance is reserved between the two limit rollers. Since the two limit rollers which are spaced by a certain distance are arranged for turning on or off the limit switch, ascending or descending limit positions of a rolling door can be reached, a safety distance is reserved for ascending or descending of the rolling door, and accidents such as collision due to excessive ascending or descending can be prevented effectively.
Description
Technical field
The present invention relates to the door-rolling machine technical field, particularly a kind of door-rolling machine range limiter.
Background technology
Owing to door-rolling machine has advantages such as easy to use, that institute takes up space; Can see that a large amount of door-rolling machines is using in the shop, market etc.; The big extremely department of door-rolling machine that uses now all adopts shakes control control, and rolling door generally all adopts metal material to process, and has certain weight; Therefore the rising of rolling door and decline all should have a lead limit switch to control, to prevent because of excessively rising or descend accidents such as causing collision.
Summary of the invention
For solving defective and the problem that door-rolling machine exists in the prior art, a kind of safe and reliable door-rolling machine range limiter is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: door-rolling machine range limiter of the present invention comprises a spacing housing; The both sides of spacing housing are provided with fixed connecting plate; An output connecting axle passes across the fixed connecting plate of spacing housing; On the output connecting axle between the fixed connecting plate of both sides, be provided with rotary threaded, on rotary threaded, be provided with two limited rollers, be provided with certain distance between two limited rollers.
The invention has the beneficial effects as follows: compared with prior art; Door-rolling machine range limiter of the present invention is through being provided with two limited rollers that are separated with certain distance; Through two limited rollers with open or closed limit switch; With rising that reaches rolling door or the extreme position that descends, make the rising of rolling door or descend to have the distance of a safety, can prevent effectively that rolling door is because of excessively rising or descend accidents such as causing collision.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment door-rolling machine range limiter of the present invention is described further.
Fig. 1 is the perspective view of door-rolling machine range limiter of the present invention.
The specific embodiment
As shown in Figure 1, door-rolling machine range limiter of the present invention comprises a spacing housing 10, and the both sides of spacing housing 10 are provided with fixed connecting plate 11; An output connecting axle 20 passes across the fixed connecting plate 11 of spacing housing 10; Output connecting axle 20 device with the volume chain of door-rolling machine and is connected, and in the rising or decline process of door-rolling machine, output connecting axle 20 is and then rotation also; On the output connecting axle 20 between the both sides fixed connecting plate 11, be provided with rotary threaded 21; Be provided with certain distance being provided with on the rotary threaded 21 between 22, two limited rollers 22 of two limited rollers, on spacing housing 10, the limit switch (not shown) be installed in addition.
As shown in Figure 1, in actual use, in the rising of door-rolling machine or the decline process; Output connecting axle 20 is and then rotation also, and the rotation of output connecting axle 20 causes two limited rollers 22 perhaps to move right to left movement, when running into the limit switch on the left side or the right at the volley; Limit switch is triggered, and the motor power of door-rolling machine is cut off, and door-rolling machine oneself is moving to be stopped; Thereby unconfined rising of rolling door or decline have been prevented; With rising that reaches rolling door or the extreme position that descends, make the rising of rolling door or descend to have the distance of a safety, can prevent effectively that door-rolling machine is because of excessively rising or descend accidents such as causing collision.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection domain that limits claim that those skilled in the art can make change and/or revise.
