Description

Protective fence

Technical Field

The utility model belongs to the technical field of the protection rail, more specifically say, in particular to protection rail.

Background

In road construction, particularly in the construction of roads with relatively high traffic flow, protective measures are generally required to be taken around a construction site, and fences are arranged around the constructed roads, so as to warn surrounding vehicles or pedestrians, namely, a building construction site, and prevent unnecessary accidents.

The following disadvantages exist for the current protective fence: the current protective enclosures are inconvenient to assemble, consume a large amount of time, and occupy a large storage location when disassembled.

Therefore, in view of the above, research and improvement are made for the existing structure and defects, and a protection fence is provided to achieve the purpose of higher practical value.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a protection rail to solve the inconvenient consumption plenty of time of current protection rail assembly, and occupy the problem of great parking position when dismantling.

The utility model relates to a purpose and efficiency of protection rail is reached by following specific technological means:

a protective fence comprises a counterweight seat; the top intermediate position of counter weight seat and the bottom intermediate position fixed connection of carriage, the front end position and the bounding wall rear end intermediate position sliding connection of carriage, the inboard below position of carriage is provided with the baffle, and the dead eye has been seted up to the baffle intermediate position of carriage, and the dead eye internal rotation of carriage is connected with the threaded rod, and the threaded rod is located the inside intermediate position of counter weight seat.

Further, carriage rear end both sides position equal fixedly connected with otic placode, two otic placodes are the symmetry and set up, and two otic placode side intermediate positions have all seted up the commentaries on classics hole.

Furthermore, the rotary holes of the two lug plates are respectively and rotatably connected with the two sides of a worm, and the worm is positioned below the rear end of the sliding frame.

Furthermore, the middle positions of the rear ends of the two lug plates are respectively connected with a bolt in a rotating mode, and the front end positions of the two bolts are attached to the two sides of the worm.

Furthermore, the bottom position of the threaded rod is fixedly connected with a worm wheel, the rear end position of the worm wheel is meshed with the worm, and the worm wheel is located below the sliding frame partition plate.

Furthermore, a threaded block is fixedly connected to the lower position in the middle of the rear end of the enclosing plate, the threaded block is located in the middle of the inner portion of the sliding frame, and the threaded rod is rotatably connected into a threaded hole of the threaded block.

Compared with the prior art, the utility model discloses following beneficial effect has:

drive the worm wheel through the worm and rotate, and then make the threaded rod rotate, through the cooperation of threaded rod and screw thread piece in this time, drive the bounding wall and remove to the top position in carriage front position, make its this device expand the protection, improved the efficiency of installation to when dismantling, the contra-rotation worm drives worm wheel contra-rotation, makes its bounding wall position descend to carriage front position, reduces the overall space of this device and occupies, is convenient for accomodate.

Because the rear end intermediate position of two otic placodes all rotates and is connected with a bolt, the front position of two bolts and the laminating of worm both sides position mutually, when screwing up two bolts, avoid the worm to rotate, it is the not hard up condition of single bolt appearance and can not lead to the worm to rotate promptly.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

The embodiment is as follows:

as shown in figures 1 to 4:

the utility model provides a protective fence, which comprises a counterweight seat 1; top intermediate position and the bottom intermediate position fixed connection of carriage 101 of counter weight seat 1, the front end position and the 2 rear end intermediate position sliding connection of bounding wall of carriage 101, below position fixedly connected with thread block 201 in the middle of the 2 rear ends of bounding wall, thread block 201 is located the inside intermediate position of carriage 101, and threaded rod 105 rotates and connects in the threaded hole of thread block 201, the inboard below position of carriage 101 is provided with the baffle, the dead eye has been seted up to the baffle intermediate position of carriage 101, the dead eye internal rotation of carriage 101 is connected with threaded rod 105, threaded rod 105 is located the inside intermediate position of counter weight seat 1.

Wherein, lug plate 102 of equal fixedly connected with in carriage 101 rear end both sides position, two lug plates 102 are the symmetry setting, and two lug plate 102 side intermediate positions have all seted up the commentaries on classics hole, rotate with worm 103 both sides position respectively in the commentaries on classics hole of two lug plates 102 and be connected, worm 103 is located carriage 101 rear end below position, the rear end intermediate position of two lug plates 102 all rotates and is connected with a bolt 104, the front end position and the worm 103 both sides position of two bolts 104 are laminated mutually, the bottom position fixedly connected with worm wheel 106 of threaded rod 105, the rear end position and the worm 103 of worm wheel 106 mesh mutually, and worm wheel 106 is located carriage 101 baffle below position, when screwing up two bolts 104, avoid worm 103 to rotate.

The specific use mode and function of the embodiment are as follows:

when using this device, at first with this device wholly carry out relative equipment, when needs put this device in the use, fix counterweight seat 1 to ground position, next rotate worm 103, drive worm wheel 106 through worm 103 and rotate, and then make threaded rod 105 rotate, this time through the cooperation of threaded rod 105 with thread piece 201, it moves to drive bounding wall 2 in carriage 101 front end position top position, make its this device expand the protection, the efficiency of installation has been improved, and when dismantling, reverse rotation worm 103 drives worm wheel 106 reverse rotation, make its bounding wall 2 position descend to carriage 101 front end position, reduce the whole space of this device and occupy, and convenient for accomodate.
