Mechanical structure for limiting rotation

Technical Field

The utility model relates to a mechanical structure of rotation restriction.

Background

The power transmission of the traditional automatic cover-turning storage barrel is realized by the aid of a gear output power of a reduction gearbox driven by a motor, and the gear pulls a spring through a manipulator and pulls a cover to open and close by the spring. Therefore, the angle and the force cannot be effectively controlled, the positioning precision is not high, the more and more the power structural parts are, the more troublesome the power structural parts are, the more easily the power structural parts are, and the more easily the power structural parts are, and the opening and closing connection parts can only be near the gear box, so that the appearance, the size and the shape of the product are.

Disclosure of Invention

The utility model aims at providing a rotation restriction's mechanical structure. This theory of operation can make the product power transmission who relies on power flip simplify more effectively, because power structure spare is less, uses this theory of operation's product, and its shape, size and outward appearance can be more diversified.

In order to achieve the purpose, the following technical scheme is specifically adopted:

a mechanical configuration for rotation limitation. The mechanical structure consists of a driving motor, an angle limiting module, a limiting pin, a two-way sleeve, a transmission shaft lever and a turnover cover, wherein the driving motor is clamped and sleeved on the angle limiting module, the limiting pin is clamped and sleeved on a driving shaft of the driving motor, and the limiting pin and a limiting baffle groove on the angle limiting module are arranged in a crossed manner; the two-way sleeve is used for sleeving a flat end of a driving shaft of the driving motor and a flat end of the transmission shaft rod on the same straight line, and the screw hole end of the transmission shaft rod is screwed on the turnover cover through a screw.

Preferably, the exposed part of the rotating shaft of the driving motor is a milling flat shaft.

Preferably, the angle limiting module is convexly provided with two limiting blocking grooves, and the two limiting blocking grooves are distributed on two sides of the rotating shaft of the driving motor.

Preferably, the middle hole of the limiting pin is a flat hole, and two angle clamping feet with preset angles are arranged on the outer edge of the limiting pin.

Preferably, the two-way sleeve is a straight pipe with flat openings at two ends.

Preferably, the transmission shaft rod is a circular straight shaft with one end pressed with a flat position and the other end provided with a screw hole.

The driving motor's in this mechanical structure drive shaft is just or the reverse rotation, drive the spacer pin in step, bi-pass sleeve pipe and transmission axostylus axostyle are just or the reverse rotation, then drive and fix the flip on the transmission axostylus axostyle and just or when the reverse rotation runs into two spacing groove bottoms of the spacing module of angle along with driving motor's drive shaft, the rotation of spacer pin is compelled and is stopped, flat position hole lock on the spacer pin simultaneously inserts the cover at downthehole driving motor's drive shaft, the rotation of driving motor drive shaft is stopped by force, with the synchronous integrative pivoted bi-pass sleeve pipe of driving motor drive shaft, transmission axostylus axostyle and flip stall simultaneously, reach the purpose of accurate control flip angle that opens and shuts.

Fig. 1 is a schematic view of a mechanical structure of the present invention.

Detailed Description

The present invention will be further explained with reference to fig. 1:

as shown in the figure, the mechanical structure for limiting rotation comprises a driving motor 1, an angle limiting module 2, a limiting pin 3, a double-pass sleeve 5, a transmission shaft lever 6 and a turnover cover 8. The driving motor 1 is clamped and sleeved on the angle limiting module 2, the limiting pin 3 is clamped and sleeved on the driving shaft 101 of the driving motor 1 through the flat position hole 303, and meanwhile, the limiting pin 3 and the limiting

baffle grooves

401 and 402 on the angle limiting module 2 form a 90-degree crossed angle; one end of the two-way sleeve 5 is sleeved on the driving shaft 101 of the driving motor 1, the other end of the two-way sleeve 5 is sleeved on the flat joint 601 of the transmission shaft lever 6, and the driving shaft 101 and the transmission shaft lever 6 are sleeved together through the two-way sleeve 5. The screw 801 is screwed to the lid 8 through the screw hole 701 of the transmission shaft 6, and the screw 802 is screwed to the lid 8 through the screw hole 702 of the transmission shaft 6.

Driving motor 1's drive shaft 101 rotates, drive spacer pin 3 in step, bi-pass sleeve pipe 5 and transmission axostylus axostyle 6 rotate, then the drive is fixed and is twisted solid flip 8 on transmission axostylus axostyle 6 and rotate, when angle card foot 301 of spacer pin 3 rotates and touch the spacing groove 401 of angle spacing module 2, the rotation of spacer pin 3 is compelled to stop, flat position hole 303 lock on the spacer pin 3 simultaneously dies the plug bush at the downthehole drive shaft 101 of self, the rotation of drive shaft 101 is stopped by force, with synchronous pivoted bi-pass sleeve pipe 5 of drive shaft 101, transmission axostylus axostyle 6 and flip 8 stall simultaneously.

When the angle clamping leg 302 of the limit pin 3 rotates and touches the limit blocking groove 402 of the angle limit module 2, the rotation of the limit pin 3 is forced to stop, meanwhile, the flat position hole 303 on the limit pin 3 locks the driving shaft 101 inserted in the self hole, the rotation of the driving shaft 101 is forced to stop, and the two-way sleeve 5, the transmission shaft lever 6 and the flip cover 8 which rotate synchronously with the driving shaft 101 stop rotating at the same time.
