Abstract
The utility model particularly relates to a rack rod connecting buckle for a building. The rack rod connecting buckle comprises a pair of curved plywood which are connected by a pin shaft; the rack rod connecting buckle is characterized in that an inwardly projecting limit device is arranged at the middle part of the inner wall of each curved plywood. The rack rod connecting buckle provided by the utility model has the advantages of simple structure, low cost, flexibility and convenience in use, and high safety performance. According to the utility model, the limit device is arranged at the middle part of the inner wall of each curved plywood; thus, when the rack rods are clamped, a constructor can respectively insert the two rack rods in connecting buckles with great force, when the end parts of the two rack rods reach the limit devices and cannot be inserted any more, the curved plywood can be clamped, the lengths of the two rack rods inserted in the connecting buckles can be ensured to be the same, uniform force applied to the two rack rods can be ensured, and an accident of falling apart is prevented. The limit devices can be formed in one step when the curved plywood is cast and molded, the strength can be ensured, and the limit devices are not damaged when the rack rods are inserted.
Description
Technical field
The utility model is specifically related to a kind of hack lever for building and connects button.
Background technology
Often need be in the building operations with hack lever butt joint lengthening, existing hack lever connects button and is mostly to be made up of the curved splint of two hinged approximate semicircles, and the end with two hack levers during use is put in two curved splints; Use bolt, nut to link closely and to use; The hack lever of this structure connects its defective of button and is that two hack levers put into the sensation that the length of curved splint relies on the construction worker fully, in clamping process, a hack lever occurs wherein through regular meeting and inserts that to connect the length of smashing long; Another root inserts and connects the length weak point of smashing; Perhaps the length of two hack lever insertions is all not enough, can cause the hack lever end of inserting weak point stressed big, yielding like this; Hack lever taking place easily fall apart, causes security incident.
Summary of the invention
The purpose of the utility model is to solve the prior art hack lever and connects button and can't guarantee that two hack levers insert the defective that connects length in the button, provide a kind of simple in structure, cost is low, can guarantee that two hack levers insert connects that the identical hack lever for building of length connects button in the button.
The utility model is realized through following technical scheme:
Be that a kind of hack lever for building connects button, comprise a pair of curved splint that connects with bearing pin, it is characterized in that the inwall middle part of said curved splint is provided with inwardly protruded stopping means.
A preferred version as the utility model: stopping means is positioned on the inwall of a curved splint.
Another preferred version as the utility model: stopping means is positioned on the inwall of two curved splints, and the stopping means of two curved splint inwalls is symmetrical set.
A preferred version as the utility model: stopping means is protruding with the arcuation of curved splint inwall coupling.
A preferred version as the utility model: stopping means is a plurality of triangular hills that are distributed in curved splint inwall middle part.
A preferred version as the utility model: stopping means is a plurality of rectangular preiections that are distributed in curved splint inwall middle part.
The utlity model has simple in structure, cost is low, flexible and convenient to use, advantage that security performance is high.The utility model is provided with stopping means at curved splint inwall middle part, and when clamping hack lever, the constructor firmly inserts two hack levers to connect respectively and smashs like this; When the end of two hack levers all arrives stopping means; Can't insert inwards, clamp curved splint this moment again, can guarantee that two hack levers insert the length unanimity of interface; Guarantee that two hack levers are stressed evenly, the difficult accident of falling apart.The stopping means of the utility model can one-shot forming when the curved splint cast molding, and guaranteed strength can not damaged stopping means when inserting hack lever.
Description of drawings
Fig. 1 is the structural representation of the utility model body;
Structural representation when Fig. 2 is the arcuation convexity for the utility model stopping means;
Structural representation when Fig. 3 is a plurality of triangular hill for the utility model stopping means;
Structural representation when Fig. 4 is a plurality of rectangular preiection for the utility model stopping means.
Shown in figure: 1 curved splint; 2 stopping means; 3 bearing pins; 4 stopping means; 5 curved splints.
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model.
Embodiment 1
Like Fig. 1, shown in Figure 2, the inwall of curved splint 1, curved splint 5 middle part is provided with stopping means 2, stopping means 4, and stopping means 2, stopping means 4 are protruding with the arcuation of inwall coupling.
When clamping hack lever; The constructor firmly inserts two hack levers to connect respectively and smashs, and when the end of two hack levers all arrives stopping means 2, stopping means 4, can't insert inwards again; Clamp curved splint 1, curved splint 5 this moment; Can guarantee that two hack levers insert the length unanimity of interface, guarantee that two hack levers are stressed evenly, the difficult accident of falling apart.
Embodiment 2
As shown in Figure 3: stopping means 2, stopping means 4 are a plurality of triangular hills.Other are with embodiment 1.
Embodiment 3
As shown in Figure 4: stopping means 2, stopping means 4 are a plurality of rectangular preiections.Other are with embodiment 1.
The utility model is not limited to above embodiment, can only be arranged on the inwall middle part of a curved splint like stopping means.
