The utility model saves the spring brake head component and simplifies the structure; the eccentric sleeve is directly connected with the outer pipe, so that the contact area between the eccentric sleeve and the outer pipe is increased, the position of the locked inner pipe is more stable, and the inner pipe is not easy to wear.

Description

Rotary flower rod

Technical Field

The utility model relates to an engineering measuring instrument technical field specifically is a rotatory flower pole.

Background

In various measuring instruments, a flower rod is an indispensable tool.

The pole generally includes outer tube and telescopic inner tube, and the mode through rotating the skew cover makes the inner tube stretch out the back and fix. As shown in fig. 3 and 4, an eccentric sleeve and a spring brake head assembly are mounted at the inner end of the inner tube. The spring brake head component comprises a bottom plate, and one side of the bottom plate is provided with a wedge-shaped clamping pipe. The bottom plate is clamped between the eccentric sleeve and the inner pipe, and the clamping pipe penetrates through the eccentric sleeve. The inner tube is fixed by rotating the inner tube or the outer tube to cause the clamp tube to abut against the outer tube and to apply pressure to the outer tube.

Above-mentioned structure, not only the structure is complicated, and the area of contact of card pipe and outer tube is little moreover, and the fixed back intensity of inner tube is not high, and is difficult not hard up. Moreover, the end part of the clamping pipe is contacted with the outer pipe, so that the contact area is small, and the clamping pipe is easy to wear.

Therefore, how to overcome the above-mentioned drawbacks becomes a problem to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem in the background art, the utility model discloses a rotary flower rod.

The utility model provides a rotary flower rod, which comprises an outer tube and an inner tube which is inserted in the outer tube and can be extended, wherein the inner end of the inner tube is connected with an eccentric sleeve which is eccentrically arranged; the eccentric sleeve is pressed or separated from the outer pipe by rotating the outer pipe or the inner pipe.

The utility model saves the spring brake head component and simplifies the structure; the eccentric sleeve is directly connected with the outer pipe, so that the contact area between the eccentric sleeve and the outer pipe is increased, the position of the locked inner pipe is more stable, and the inner pipe is not easy to wear.

Eccentric cover direct mount is at the inner end of inner tube, and the position accuracy is lower, influences the locking effect of inner tube, so further improve and solve this problem, and is specific, and inner tube inner end joint has the end cap, and the outer end of end cap is provided with the spliced pole of eccentric arrangement, and eccentric cover cup joints on the spliced pole. The connecting column is used for installing and positioning the eccentric sleeve, so that the position precision is higher.

The concrete structure of end cap joint inner tube does: the inner end of the plug is provided with a clamping column and forms a shoulder; the inner tube is sleeved with the clamping column and is abutted against the shoulder.

The problem is further improved and solved because the plug is heavy and the cost is increased, and particularly, the inner end of the plug is also provided with a notch for reducing the weight of the plug.

After long-time use, the end cap is not hard up easily to the rotation for the inner tube is produced, leads to the inner tube not hard up, so further improve and solve this problem, it is concrete, the lateral part of joint post still is connected with the inner tube through the rivet.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model relates to a rotary flower rod, which comprises an outer tube 1 and an inner tube 2 inserted into the outer tube 1 and telescopic. The inner end of the inner tube 2 is fixed with a plug 4 which is concentrically arranged, and the lower end of the plug 4 is connected with an eccentric sleeve 3 which is eccentrically arranged. The eccentric sleeve 3 is pressed or separated from the outer tube 1 by rotating the outer tube 1 or the inner tube 2.

The upper end of the outer tube 1 is provided with a fixed guide cap 8, so that the outer tube 1 can be fixed by hands of people conveniently, the inner tube 2 and the outer tube 1 can rotate reversely, and the inner tube 2 is fixed.

The utility model saves the spring brake head component and simplifies the structure; eccentric cover 3 is direct to be connected with outer tube 1, has increased the area of contact of eccentric cover 3 with outer tube 1, not only makes the position more firm after the inner tube 2 locks, but also difficult wearing and tearing.

Example two:

compared with the first embodiment, the differences are as follows: the outer end of the choke plug 4 is provided with a connecting column 41 which is eccentrically arranged, and the eccentric sleeve 3 is sleeved on the connecting column 41. The lower end of the connecting column 41 is provided with a connecting plate 6 covering part of the eccentric sleeve 3, and the screw 7 penetrates through the connecting plate 6 and is in threaded connection with the connecting column 41, so that the eccentric sleeve 3 is fixed. The connecting column 41 is used for installing and positioning the eccentric sleeve 3, so that the position precision is higher.

Example three:

compared with the two examples, the difference is that: the inner end of the plug 4 is provided with a clamping column 42 and forms a shoulder; the inner tube 2 is sleeved on the clamping column 42 and abuts against the shoulder. Therefore, the plug 4 and the inner tube 2 are connected in a positioning mode, and the installation efficiency is improved.

Example four:

compared with the three phases of the embodiment, the differences are as follows: the inner end of the plug 4 is also provided with a notch 43 for reducing the weight of the plug 4 and reducing the cost.

Example five:

compared with the three phases of the embodiment, the differences are as follows: the side of the snap-in post 42 is also connected with the inner tube 2 by a rivet 5. The rivet 5 is arranged to prevent the inner tube 2 from loosening caused by the rotation of the plug 4 relative to the inner tube 2.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
