Description

Ground shaft with high safety

Technical Field

The utility model relates to a door and accessory technical field especially relate to a high ground axle of security.

Background

When the door body is used, the door body is fixed on the rotating shaft of the ground shaft, and the ground shaft body provided with the rotating shaft is fixed on the ground, so that the door body is supported and fixed. The existing ground shaft is poor in sealing performance, rainwater can flow into the ground shaft body in rainy days, the internal structure of the ground shaft is corroded, the service life is short, the door can fall off due to long-term non-replacement, and pedestrians can be accidentally injured to cause danger.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a high land axle of security, the leakproofness is high, long service life.

In order to achieve the above object, the utility model provides a high ground axle of security, the on-line screen storage device comprises a base, be equipped with the fixed orifices around the base, the center of base is equipped with the back shaft, be equipped with semicircular first recess in the back shaft, the bottom of first recess is equipped with the second recess, be equipped with the ball in the first recess, the ball with the structure phase-match of first recess, back shaft and rotation axis connection, rotation axis formula structure as an organic whole to including axle sleeve and connecting rod, the axle sleeve with back shaft external diameter structure phase-match, just be equipped with the third recess of spherical cap shape in the axle sleeve, the connecting rod is located the top of axle sleeve, just be equipped with connecting thread on the lateral surface of connecting rod.

Preferably, the diameter of the connecting rod is smaller than the diameter of the bushing.

Preferably, the third groove is matched with the part of the structure that the ball protrudes out of the supporting shaft.

Therefore, the utility model adopts the above structure the high earth's axis of security, the leakproofness is high, long service life.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model discloses the schematic diagram of high ground axle embodiment of security, fig. 2 is the utility model discloses the schematic diagram of the embodiment of base in the high ground axle of security, fig. 3 is the utility model discloses the schematic diagram of the embodiment of ball in the high ground axle of security, as shown in the figure, a high ground axle of security, including base 1, base 1 is equipped with fixed orifices 2 all around, and fixed orifices 2 is used for fixing the whole of ground axle with fixing bolt cooperation use. The center of base 1 is equipped with back shaft 3, is equipped with semicircular first recess 4 in the back shaft 3, is equipped with ball 5 in the first recess 4, and ball 5 and first recess 4's structure phase-match, ball 5 can roll in first recess 4. The bottom of first recess 4 is equipped with second recess 6, and second recess 6 can increase first recess 4 and ball 5's area of contact, and then increases ball 5's the biggest bearing, guarantees ball 5's life.

The support shaft 3 is connected with the rotating shaft 7, the rotating shaft 7 is of an integrated structure and comprises a shaft sleeve 71 and a connecting rod 72, and the diameter of the connecting rod 72 is smaller than that of the shaft sleeve 71.

Axle sleeve

71 and 3 external diameter structures phase-matches of back shaft, and axle sleeve 71 seals ball 5 with the cooperation of back shaft 3, prevents that the rainwater from flowing into and corroding ball 5 in the first recess 4, has guaranteed ball 5's life. A third spherical-crown-shaped groove is formed in the shaft sleeve 71, and the third groove is matched with a part of the structure of the ball 5 protruding out of the support shaft 3. The connecting rod 72 is located at the top of the shaft sleeve 71, and the outer side surface of the connecting rod 72 is provided with connecting threads which are used for being connected with the door structure.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
