Abstract
The invention provides a key-type plug pin. The key-type plug pin comprises a connector body and a plug pin body arranged below the connector body. The side face of the connector body is provided with a sink cavity jointed with the end of a cross rod. The lower portion of the plug pin body is provided with a through channel. A movable locking plate is installed in the channel. The locking plate is in a long strip shape, the length of the locking plate is not larger than that of the channel, and the width of the locking plate is not larger than that of the channel. A self-locking structure is additionally arranged, and therefore self-locking can be realized easily. The key-type plug pin has enough strength, rigidity and stability, and construction smoothness and safety are guaranteed. The key-type plug pin is simple in structure, convenient to assemble and disassemble, stable in performance, safe, reliable and capable of being used repeatedly in a turnover mode, and amortization cost is lowered.
Description
Technical field
The present invention relates to steel pipe scaffold field, particularly relate to a kind of keyed latch.
Background technology
Scaffold is requisite operation facility in building trade, and existing scaffold is generally by steel pipe and steel pipe
Fastener forms.In practical operation, wall-connecting piece is embedded in body of wall, and cross bar is connected with each other with wall-connecting piece by latch.
Existing latch does not has self-locking structure, uses middle potential safety hazard very big, for security consideration, it is necessary to often send
Scaffold connector and latch are checked and change by people, add engineering cost.
Summary of the invention
For the defect of prior art, it is desirable to provide a kind of keyed latch, add self-locking structure, knot
Structure is simple, easy to loading and unloading, stable performance, safe and reliable.
In order to realize above-mentioned technical purpose, the present invention uses following technological means: a kind of keyed latch, including connecing
Head body and be arranged on the latch below joint body, the side of described joint body is provided with and engages with crossbar end
Heavy chamber, it is characterised in that: described latch bottom has the passage run through, and installs in described passage mobilizable
Locking plate, described locking plate is elongated, and the length of described locking plate is not more than the length of passage, the width of described locking plate
It is not more than the width of passage.
Further, described heavy intracavity has the through hole run through.
Beneficial effects of the present invention: a kind of keyed latch that the present invention provides, adds self-locking structure, during use,
The present invention being inserted in connection ring, locking plate is the most sagging according to the effect of gravity, it is achieved self-locking；During dismounting, will
Locking plate is put in passage, then is taken out from connection ring by latch.The present invention has enough intensity, rigidity
And degree of stability, it is ensured that construct smoothly and safety.Present configuration is simple, be convenient to mount and dismount, stable performance, safety
Reliably, can repeatedly have enough to meet the need use, reduce amortization charge and use.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to shown in Fig. 1, Fig. 2, a kind of keyed latch that the present invention provides, including joint body 1 and setting
Latch 2 below joint body 1, the side of described joint body 1 is provided with and engages with cross bar 10 end
Heavy chamber 3.Owing to have employed said structure, cross bar 10 end is coordinated with heavy chamber 3 weld during fabrication, fixed
Position is convenient, and bonding strength is high.Described latch 2 bottom has the passage 4 run through, and installs movable in passage 4
Locking plate 5, locking plate 5 is elongated, and the length of locking plate 5 is not more than the length of passage 4, the width of locking plate 5
It is not more than the width of passage 4.During use, conventionally the present invention is inserted in connection ring 9, locking plate 5
The most sagging according to the effect of gravity, it is achieved self-locking, prevent latch 2 be connected ring 9 disengaging, it is ensured that use
Safety；During dismounting, locking plate 5 is put in passage 4, then latch 2 is taken out from connection ring 9, behaviour
Make simple and convenient.
As more preferable embodiment, have, in described heavy chamber 3, the through hole 6 run through.Design one side of through hole 6
Face alleviates the overall weight of the present invention, energy-conserving and environment-protective, is on the other hand conducive to heavy chamber 3 to weld with cross bar 10 end
Laminating when connecing is stable.
With reference to shown in Fig. 3, during use, pre-buried wall-connecting piece 8 in body of wall 7, by cross bar 10 end and heavy chamber 3
Coordinate welding, locking plate 5 is put in passage 4, then latch 2 is inserted in connection ring 9, locking plate 5 foundation
The effect of gravity is the most sagging, it is achieved self-locking, prevent latch 2 be connected ring 9 disengaging, it is ensured that cross bar 10
With being stably connected with of body of wall 7；During dismounting, locking plate 5 is put in passage 4, then by latch 2 from connecting ring 9
In take out, simple to operation.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that,
For those skilled in the art, some improvement without departing from the principles of the present invention and
Retouching, these improvements and modifications also should be regarded as protection scope of the present invention.
