Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a portable security fence, include tripod support frame 10 and fix the main pole setting 20 on tripod support frame 10, the upper end of main pole setting 20 is connected with lift pole setting 40 through adaptor 30, be provided with the couple 41 of connecting the purse seine on the lift pole setting 40, adaptor 30 includes the connection piece 31 that a plurality of are parallel to each other, each connection piece 31 one end and lift pole setting 40's lower extreme articulated, the other end is articulated with the upper end of main pole setting 20.

Based on above-mentioned security fence's current structure, one of the characteristics of this embodiment lies in, the height-adjustable of lift pole setting 40 can carry out the adaptability adjustment according to the in-service use occasion, and the practicality is strong.

Specifically, because the connecting piece 31, the lifting upright rod 40 and the main upright rod 20 are all in a hinged connection mode, one end of the connecting piece 31 connected with the main upright rod 20 is rotated downwards to drive the other end of the connecting piece 31 to rotate upwards, so as to drive the lifting upright rod 40 connected with the other end of the connecting piece 31 to move upwards, and further extend the height of the lifting upright rod 40, in order to facilitate the rotation of the connecting piece 31, a rotation operation hole 311 is formed in the end portion of the connecting piece 31, and an operation rod extends into the rotation operation hole 311 and drives the connecting piece 31 to rotate.

The second characteristic of this embodiment lies in that the base structure is slim and graceful, and the shrink of being convenient for and firm type are good, specifically, tripod support frame 10 includes tripod 12 and crossbeam 13, the upper end and the main pole setting 20 of tripod 12 are articulated, the lower extreme and the sliding roller 11 of tripod 12 are connected, the middle part and the one end of crossbeam 13 of tripod 12 are articulated, the other end and the main pole setting 20 of crossbeam 13 are articulated.

The base of similar tripod structure compares in traditional iron pier formula base weight lighter, the shrink of being convenient for, and the structure focus of tripod is more steady, is in simultaneously the lower extreme of tripod support frame 10 is provided with slip gyro wheel 11 and is convenient for remove, does not need the transport of difficultly.

In order to fix the position of the portable safety fence moving to the designated position and prevent the portable safety fence from further sliding, the lower end of the main upright 20 is connected with a positioning member for fixing the position of the tripod support frame 10.

Further, the main upright 20 comprises a sliding rod 21 and a fixing sleeve 22, the fixing sleeve 22 is connected with the tripod 10, and the sliding rod 21 is slidably inserted into the fixing sleeve 22.

The setting element includes sucking disc 23 and location nail 24, sucking disc 21 is provided with a plurality of, and a plurality of 23 annular of sucking disc install the lower extreme at fixed cover 22, the lower extreme at dead lever 21 is installed to location nail 24.

When the portable safety fence is applied to a smooth and flat ground, the sucker 23 arranged at the lower end of the fixing sleeve 22 can be sucked to the ground by pressing the fixing sleeve 22 downwards, so that the sliding roller 11 is prevented from continuously sliding; when portable security fence motion ground such as meadow, muddy soil again, sucking disc 23's adsorption effect is poor, consequently can further push down slide bar 21, makes the location nail 24 of slide bar 21 lower extreme insert ground inside, has both prevented rolling pulley 11's further slip and has improved portable security fence's overall device stability again, avoids being blown down under adverse conditions such as strong wind.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
