Description

Technical Field

[0001] The invention relates to a screw-type electric window opener with a motor suspended and installed. Background Art

[0002] As modern buildings pay more and more attention to fire smoke exhaust and ventilation, electric window openers are used more and more, and the number of electric window openers installed in each building is increasing; in the prior art, the motor is directly fixed on the bearing seat, and the bearing seat is fixed on the cavity of the electric window opener by screws, so that the noise generated by the motor is directly transmitted to the bearing seat and the cavity of the electric window opener, and the noise of a large number of electric window openers is transmitted to the entire building structure through the bracket, making a huge noise. Summary of the invention

[0003] The object of the present invention is to provide a screw-type electric window opener with a motor suspended and installed with low running noise.

[0004] The technical solution of the present invention is:

[0005] A screw-type electric window opener with a motor suspended installation is characterized in that: a reduction motor, an elastic connector, a bearing seat and a push rod are included in an outer shell tube; the bearing seat is fixed in the outer shell tube by screws, and a hole is opened on the side of the bearing seat; the top of the reduction motor is fixed to the end face of the elastic connector by screws, and a groove hole is opened on the side of the elastic connector; an elastic element is inserted between the groove hole and the hole on the side of the bearing seat, so that the reduction motor is suspended and connected to the bearing seat.

[0006] The elastic connector is a hollow cavity, the end surface of which is fixed to the top of the reduction motor by screws, and a groove hole is opened on the side surface.

[0007] The reduction motor drives the flat position of the output shaft and the flat position of the end of the push rod. The flat position of the output shaft and the flat position of the end of the push rod are connected through a coupling sleeve, and the coupling sleeve is installed in the hollow cavity of the elastic connector.

[0008] The coupling sleeve has a flat hole shape and is sleeved with a gap on the flat position of the output shaft driven by the reduction motor and the flat position of the end of the push rod.

[0009] Furthermore, the push rod includes a screw rod, a stop nut and a push rod tube; one end of the screw rod is fixed to the bearing seat through a rolling bearing, and the other end is equipped with a stop nut, and the push rod tube is fixed on the stop nut.

[0010] The present invention disconnects the rigid connection between the traditional motor and the bearing seat, and uses an elastic element to bear the driving torque and flexibly fix the reduction motor, so that the electric window opener is noise-free. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Figure 1 It is a schematic structural diagram of an embodiment of the present invention.

[0013] Figure 2 It is a schematic diagram of the structure of the elastic connector of the present invention. DETAILED DESCRIPTION

[0014] A screw-type electric window opener with a motor suspended installation, wherein a reduction motor 02, an elastic connector 04, a bearing seat 05 and a push rod 09 are arranged in a housing tube 01; the bearing seat 05 is fixed in the housing tube 01 by screws, and a hole is opened on the side of the bearing seat 05; the top of the reduction motor 02 is fixed to the end face of the elastic connector 04 by screws, and a groove hole is opened on the side of the elastic connector 04; an elastic element is inserted between the groove hole and the hole on the side of the bearing seat 05, so that the reduction motor 02 is suspended and connected to the bearing seat 05. Compared with the existing screw-type window opener, the elastic element bears the driving torque and flexibly fixes the reduction motor 02.

[0015] The elastic connector 04 is a hollow cavity, the end face of which is fixed to the top of the reduction motor 02 by screws, and a groove hole is opened on the side.

[0016] The reduction motor 02 drives the shaft flat position and the push rod end flat position, and drives the shaft flat position to be connected with the push rod end flat position through a coupling sleeve 03, and the coupling sleeve 03 is installed in the hollow cavity of the elastic connector.

[0017] The hole in the coupling sleeve 03 is in a flat hole shape and is mounted on the flat shaft of the reduction motor 02 and the flat shaft at the end of the screw 08 with clearance.

[0018] The push rod comprises a screw rod 08 , a stop nut 07 and a push rod tube 09 ; one end of the screw rod 08 is fixed on the bearing seat 05 through a rolling bearing 06 , and the other end is provided with a stop nut 07 , on which the push rod tube 09 is fixed.

[0019] Partial modification of the technical solutions of the above implementation cases, or equivalent replacement and improvement of some of the technical features therein, should all be included in the protection scope of the present invention.
