Technical Field
[0001] The utility model relates to the field of tubular motors, in particular to a novel small-thrust tubular motor. Background Art
[0002] Tubular motors are widely used in rolling shutters. Traditional garage rolling shutters are relatively wide, so conventional tubular motors are used for operation. However, for relatively narrow rolling shutters, traditional tubular motors are too long and not suitable for narrow-width situations. Therefore, a tubular motor with a smaller specification and shorter length is adopted. Also, because it is applied to relatively narrow rolling shutters and the width is uncertain, the tubular motor with a smaller specification may still have insufficient length. For this reason, a novel small-thrust tubular motor is designed. Content of the Utility Model

A spline groove is arranged on the outer side of the driving end. The diameter of the driving end is larger than the diameter of the tubular motor structure. The front end of the adjustable outer sleeve at the driving end is fixed in the spline groove on the outer side of the driving end by screws. The rear end of the adjustable outer sleeve at the driving end is fixed on the outer side of the sliding bearing by screws. The inner diameter of the adjustable outer sleeve at the driving end is larger than the diameter of the tubular motor structure. The adjustable outer sleeve at the driving end rotates on the outer side of the tubular motor structure.

Detailed Description of the Embodiment
[0012] The present utility model will be further elaborated in detail below in conjunction with the drawings and specific embodiments.
[0013] A new type of small-thrust tubular motor includes a tubular motor body 1, a motor body fixed end 2, and an adjustable outer sleeve 3 at the driving end.

[0014] The tubular motor body 1 is composed of a tubular motor structure 5, a drive end 6, and a sliding bearing 7. A spline sliding groove 8 is provided in the middle section of the tubular motor structure 5. The sliding bearing 7 is arranged in the spline sliding groove 8 and can slide horizontally in the spline sliding groove 8. The drive end 6 is connected to the front end of the tubular motor structure 5. The rear end of the tubular motor structure 5 is fixed on the motor body fixed end 2. A spline groove 9 is provided on the outer side of the drive end 6. The diameter of the drive end 6 is larger than that of the tubular motor structure 5. The front end of the adjustable outer sleeve 3 of the drive end is fixed in the spline groove 9 on the outer side of the drive end 6 through a screw 4. The rear end of the adjustable outer sleeve 3 of the drive end is fixed on the outer side of the sliding bearing 7 through a screw 4, and the inner diameter of the adjustable outer sleeve 3 of the drive end is larger than the diameter of the tubular motor structure 5. The adjustable outer sleeve 3 of the drive end rotates on the outer side of the tubular motor structure 5.
[0015] The adjustable outer sleeve 3 of the drive end is composed of a bearing fixing sleeve 10, a drive end plate 11, and parallel rods 12. The bearing fixing sleeve 10 and the drive end plate 11 are arranged oppositely. A plurality of groups of parallel rods 12 are provided.
