Description
Technical field
The utility model relates to steel pipe scaffold field, particularly relates to a kind of keyed latch.
Background technology
Scaffold is requisite operation facility in building trade, and existing scaffold is made up of steel pipe and steel tube fastener usually.In practical operation, wall-connecting piece is embedded in body of wall, and cross bar is interconnected by latch and wall-connecting piece.Existing latch does not have self-locking structure, uses middle potential safety hazard very large, for security consideration, constantly sends someone to check scaffold connector and latch and change, add engineering cost.
Utility model content
For the defect of prior art, the utility model aims to provide a kind of keyed latch, adds self-locking structure, and structure is simple, easy to loading and unloading, stable performance, safe and reliable.
In order to realize above-mentioned technical purpose, the utility model adopts following technological means: a kind of keyed latch, comprise joint body and be arranged on the latch below joint body, the side of described joint body is provided with the heavy chamber engaged with crossbar end, it is characterized in that: described latch bottom has the passage run through, install mobilizable locking plate in described passage, described locking plate is elongated, the length of described locking plate is not more than the length of passage, and the width of described locking plate is not more than the width of passage.
Further, the through hole run through is had in described heavy chamber.
The beneficial effects of the utility model: a kind of keyed latch that the utility model provides, add self-locking structure, during use, are inserted by the utility model in connecting ring, and locking plate is automatically sagging according to the effect of gravity, realizes self-locking; During dismounting, locking plate is put into passage, then latch is taken out from connecting ring.The utility model has enough intensity, rigidity and stability, ensures to construct smoothly and safety.The utility model structure is simple, mounting or dismounting convenience, stable performance, safe and reliable, repeatedly can have enough to meet the need use, reduce amortization charge use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model;
Fig. 3 is assembling schematic diagram of the present utility model;
Wherein: 1, joint body; 2, latch; 3, heavy chamber; 4, passage; 5, locking plate; 6, through hole; 7, body of wall; 8, wall-connecting piece; 9, connecting ring; 10, cross bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to shown in Fig. 1, Fig. 2, a kind of keyed latch that the utility model provides, the latch 2 comprising joint body 1 and be arranged on below joint body 1, the side of described joint body 1 is provided with the heavy chamber 3 with cross bar 10 engaged at end.Owing to have employed said structure, coordinated cross bar 10 end during fabrication weld with heavy chamber 3, location is convenient, and bonding strength is high.Described latch 2 bottom has the passage 4 run through, and install mobilizable locking plate 5 in passage 4, locking plate 5 is elongated, and the length of locking plate 5 is not more than the length of passage 4, and the width of locking plate 5 is not more than the width of passage 4.During use, conventionally inserted by the utility model in connecting ring 9, locking plate 5 is automatically sagging according to the effect of gravity, realizes self-locking, prevents latch 2 and the disengaging of connecting ring 9, ensures use safety; During dismounting, locking plate 5 is put into passage 4, then latch 2 is taken out from connecting ring 9, simple to operation.
As better embodiment, in described heavy chamber 3, have the through hole 6 run through.The design of through hole 6 alleviates overall weight of the present utility model, energy-conserving and environment-protective on the one hand, is conducive to heavy chamber 3 on the other hand and stablizes with laminating during cross bar 10 welding edges.
With reference to shown in Fig. 3, during use, pre-buried wall-connecting piece 8 in body of wall 7, cross bar 10 end is coordinated with heavy chamber 3 and welds, locking plate 5 is put into passage 4, then latch 2 is inserted in connecting ring 9, locking plate 5 is automatically sagging according to the effect of gravity, realize self-locking, prevent latch 2 and the disengaging of connecting ring 9, ensure that cross bar 10 is connected with the stable of body of wall 7; During dismounting, locking plate 5 is put into passage 4, then latch 2 is taken out from connecting ring 9, simple to operation.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a keyed latch, comprise joint body and be arranged on the latch below joint body, the side of described joint body is provided with the heavy chamber engaged with crossbar end, it is characterized in that: described latch bottom has the passage run through, in described passage, mobilizable locking plate is installed, described locking plate is elongated, and the length of described locking plate is not more than the length of passage, and the width of described locking plate is not more than the width of passage.
2. a kind of keyed latch according to claim 1, is characterized in that: have the through hole run through in described heavy chamber.
