Abstract
The utility model discloses a ball screw hanging arm type door opener. The ball screw hanging arm type door opener comprises an inner connecting rod and an outer connecting rod, wherein one end of the inner connecting rod extends to the inside of the outer connecting rod, a motor is fixed at one end of the outer connecting rod, the motor is connected with a threaded rod which extends to the inside of the inner connecting rod, and a bearing assembly is installed between the threaded rod and the inner connecting rod. The ball screw hanging arm type door opener carries out transmission by using a ball screw threaded rod mode. Due to the facts that a ball screw threaded rod is in rolling friction, friction is small, transmission efficiency is high, and self locking is not prone to happen, a minor lead angle can be directly and manually loosened by using a lead angle, reverse starting is small, and transmission efficiency is improved.
Description
Technical field
The utility model relates to a kind of door lifter.
Background technology
Tradition is hung arm-type door lifter and is used the trapezoidal screw transmission, because trapezoidal screw is sliding friction, friction is big, the low and easy self-locking of transmission efficiency, thus little lead angle can't directly utilize lead angle to carry out hand break loose and cause oppositely and can't start.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of friction little, and transmission efficiency ball screw high and that be difficult for self-locking is hung arm-type door lifter.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of ball screw is hung arm-type door lifter, comprise inside connecting rod and outside connecting rod, one end of described inside connecting rod stretches in the described outside connecting rod, one end of described outside connecting rod fixedly has motor, described motor is connected with the threaded rod that stretches into described inside connecting rod inside, between described threaded rod and the inside connecting rod bearing assembly is installed.
Described bearing assembly comprises axle sleeve and return duct, the inwall of described axle sleeve is provided with the spiral helicine ball orbit consistent with the screw thread on the described threaded rod, the sidewall of described axle sleeve is provided with two return ports and is communicated with the two ends of described ball orbit respectively, the two ends of described return duct are communicated with two described return ports respectively, between the thread groove on described ball orbit and the described threaded rod ball are installed.
The two ends of described axle sleeve are equipped with plug.
The two ends of described threaded rod are equipped with buffer spring.
The beneficial effects of the utility model are: between threaded rod of the present utility model and the inside connecting rod bearing assembly is installed, uses the transmission of ball screw mode, because ball screw is rolling friction; It is little to rub, and transmission efficiency is high and be difficult for self-locking, thereby can realize that the minor spiral lift angle can directly use lead angle to carry out hand break loose and oppositely start diminishing, and transmission efficiency improves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structure sectional view of the present utility model;
Fig. 2 is the enlarged drawing at A place among Fig. 1;
Fig. 3 is the sectional view of bearing assembly;
Fig. 4 is the exploded view of bearing assembly.
The specific embodiment
Referring to figs. 1 through 4, a kind of ball screw is hung arm-type door lifter, comprise inside connecting rod 4 and outside connecting rod 2, inside connecting rod 4 and outside connecting rod 2 are tubulose, one end of described inside connecting rod 4 stretches into described outside connecting rod interior 2, one end of described outside connecting rod 2 fixedly has motor 1, and described motor 2 is connected with the threaded rod 5 that stretches into described inside connecting rod 4 inside, in the described threaded rod and between the inside connecting rod 4 bearing assembly is installed.
Described bearing assembly comprises axle sleeve 6 and return duct 10, the inwall of described axle sleeve 6 is provided with the spiral helicine ball orbit 11 consistent with the screw thread on the described threaded rod 5, the sidewall of described axle sleeve 6 is provided with two return ports 8 and is communicated with the two ends of described ball orbit 11 respectively, the two ends of described return duct 10 are communicated with two described return ports 8 respectively, between the thread groove on described ball orbit 11 and the described threaded rod 5 ball 9 are installed.
The two ends of described axle sleeve 6 are equipped with plug 7, can place the ball dislocation.
The two ends of described threaded rod 5 are equipped with buffer spring 3, open the door put in place or close the door put in place after, buffer spring can play cushioning effect.
Because axle sleeve is fixed on the inside connecting rod 4, driven by motor threaded rod 5 rotates, threaded rod 5 is done axial motion, and ball 9 moves to the end of ball orbit 11 from the movement along with threaded rod 5 of the initiating terminal of ball orbit 11, and then enter into return port 8, in the back under the promotion of ball 9, get back to the initiating terminal of ball orbit 11, every all so circulation of ball again from another return port 8, constitute the transmission of ball screw mode, because ball screw is rolling friction; It is little to rub, and transmission efficiency is high and be difficult for self-locking, thereby can realize that the minor spiral lift angle can directly use lead angle to carry out hand break loose and oppositely start diminishing, and transmission efficiency improves.
