Abstract
The utility model relates to quickly assembled or disassembled guard bar with connecting pieces. The quickly assembled or disassembled guard bar comprises a guard bar body, a positioning tube and the connecting pieces, wherein each connecting piece consists of a bolt, a pin and a chain; the bolts penetrate in the guard bar body and are connected with corresponding through holes in the positioning tube in a positioned manner; the pins penetrate in through holes in the heads of the bolt and then are locked; and two ends of each chain are respectively connected with the positioning tube and the tail of the corresponding bolt. Two ends of each chain are respectively welded with the positioning tube and the tail of the corresponding bolt. The pins are formed by bending steel wires. Compared with the prior art, the quickly assembled or disassembled guard bar with the connecting pieces has the advantages that the guard bar body is fixedly connected with the positioning tube quickly and reliably by dowels; the connecting pieces are integrally connected with the positioning tube through the chains, so that the connecting pieces cannot be lost, and the guard bar is quite convenient to use; and the quickly assembled or disassembled guard bar is simple in structure, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of guard bar device, relates in particular to a kind of guard bar device of the fast demountable that carries connector.
Background technology
In Structural Engineering construction, because the construction operations such as lifting need to stay the operation holes such as hole for hoist, and in operation process, around these holes, need temporary erection guardrail, people or thing accidental falling when preventing work high above the ground.This guardrail is normally dismountable, generally uses bolt to connect, and after each connecting bolt need to being unclamped, connects, tightens when use again, and process is more loaded down with trivial details.And after setting up, can not ensure that connecting bolt is all intact at every turn, when used next time, need to get supporting connector if any disappearance could connect, and can affect to a certain extent the progress of construction.
Summary of the invention
The utility model provides a kind of quickly dismantled guardrail that carries connector, adopts pin to be connected and fixed between guardrail and positioning pipe, and fast and reliable, connector is connected with positioning pipe by chain, can ensure that connector do not lose, and uses very convenient.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of quickly dismantled guardrail that carries connector, comprise guardrail, positioning pipe and connector, described connector is made up of latch, safety pin and chain, latch is realized and being located by connecting with through hole corresponding on positioning pipe through guardrail, safety pin is through in the through hole of latch head and realizes locking, and chain two ends are connected with positioning pipe and latch afterbody respectively.
Weld with positioning pipe and latch afterbody respectively at described chain two ends.
Described other steel wire for needle bends and forms.
Compared with prior art, the beneficial effects of the utility model are:
1) between guardrail and positioning pipe, adopt pin to be connected and fixed, fast and reliable;
2) connector is connected with positioning pipe by chain, can ensure that connector do not lose, and uses very convenient;
3) simple in structure, easily to make, cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of connector described in the utility model.
In figure: 1. guardrail 2. positioning pipe 3. chain 4. latch 5. safety pins
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, a kind of quickly dismantled guardrail that carries connector of the utility model, comprise guardrail 1, positioning pipe 2 and connector, described connector forms (seeing Fig. 2) by latch 4, safety pin 5 and chain 3, latch 4 is realized and being located by connecting with the location upper corresponding through hole of 2 pipe through guardrail 1, and safety pin 5 is through in the through hole of latch 4 heads and realizes and locking, and chain 3 two ends are connected with positioning pipe 2 and latch 4 afterbodys respectively.
Weld with positioning pipe 2 and latch 4 afterbodys respectively at described chain 3 two ends.
Described safety pin 5 use steel wires bend and form.
When work, guardrail 1 is inserted in positioning pipe 2, positioning pipe 2 bottom weldings are in relevant work position, chain 3 one end are welded on positioning pipe 2, the other end and latch 4 afterbodys are welded to connect, latch 4 heads insert guardrails 1 and are located by connecting with realizing in through hole corresponding on tube connector 2, and safety pin 5 is inserted to fastening in the head through hole that alignment pin 4 passes side.While using rear dismounting guardrail, safety pin 5 is opened, extracted latch 4, pull down guardrail 1 and deposit in addition arrangement.After use, safety pin is inserted in latch head bore and deposited, because connector is fixed together by chain 3 and positioning pipe 2, only need bring guardrail 1 can re-assembly while use next time, do not need to worry to lack connector.This frame mode is no matter assembling or dismounting are all very efficient and convenient.
A kind of quickly dismantled guardrail that carries connector of the utility model is realized guardrail 1 installation location by the through hole insertion latch 4 between guardrail 1 and positioning pipe 2, insert latch 4 one side through hole with safety pin 5 and realize the fastening of guardrail 1, chain 3 is used for preventing the loss that comes off of latch 4.
The above is only general principle of the present utility model, not the utility model is imposed any restrictions, and everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
Claims (3)
1. one kind carries the quickly dismantled guardrail of connector, comprise guardrail, positioning pipe and connector, it is characterized in that, described connector is made up of latch, safety pin and chain, latch is realized and being located by connecting with through hole corresponding on positioning pipe through guardrail, safety pin is through in the through hole of latch head and realizes locking, and chain two ends are connected with positioning pipe and latch afterbody respectively.
