Abstract
The utility model relate4s to an arc board locking connection device which comprises a crook plate (1), a curved plate (3) with a long hole (5) and a location-limit rivet (4). The utility model is characterized in that: the curved plate (3) is fixed on the crook plate (1) through the location-limit rivet (4); and a column object (2) is changeably locked in the upper position or the lower position of the long hole (5) of the curved plate (3) through the location-limit rivet (4). The arc board locking connection device is of high working efficiency, strong stability and large security co-efficiency. The utility model provides a secure, simple and high-efficient connection manner.
Description
The utility model is a kind of automatic locking apparatus that blocks cylindrical object that is applicable to, the pedal that is particularly useful for above the building scaffold connects.
It generally all is to ride on the scaffold pedal is flat that pedal on the existing scaffold is installed, then with the iron wire circle tightly or use bolt.The shortcoming of prior art is to take that the speed of tearing open is slow, efficient is low, poor stability simultaneously, safety factor low (revolve to examine twist fracture excessively easily as iron wire, bolt is through shaking easy loose or dislocation etc.).
The utility model has overcome the shortcoming of prior art, and a kind of new and effective safe method of attachment is provided.
The utility model is achieved in that on a hook-type plate with two spacing rivets dress lastblocks and has the arc of elongated hole, and make it within the specific limits can be free movable.The opening of hook-type plate exposes fully when arc is in open mode, so that cylindrical object is put into.After cylindrical object is put into, will run into an end of arc, make arc be slipped to low level automatically, thereby hook-type plate opening portion is sealed, make cylindrical object locked, thereby reach the purpose of connection.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation that arc locking linkage is in open mode.
Fig. 2 is the structural representation that arc locking linkage is in the lock state.
Among the figure: 1. hook-type plate; 2. cylindrical object; 3. arc; 4. spacing rivet; 5. elongated hole.
When arc locking linkage as shown in Figure 1 was in open mode, spacing rivet 4 was in the lower end of slotted hole 5, and the opening of hook-type plate 1 exposes fully, and cylindrical object 2 can freely be put into.
When locking linkage, arc is in open mode, when cylindrical object 2 arrives the top of hook-type plates 1 opening, and the upper end that just can run into arc 3, arc 3 will be slipped to low level this moment, and arc locking linkage is in the lock state.
Arc locking linkage as shown in Figure 2 is in the lock state, and cylindrical object 2 enters in the opening of hook-type plate 1 fully, makes arc 3 be in low level, and spacing rivet 4 is in the upper end of slotted hole 5, and cylindrical object 2 is by the locking of arc locking linkage.
This arc locking linkage high efficiency, stability is strong, safety factor is big, and a kind of safe, easy, connected mode efficiently is provided.
Claims (5)
1. an arc locks linkage, include hook-type plate (1), have the arc (3) of elongated hole (5) and spacing rivet (4) is formed, it is characterized in that: described hook-type plate (1) is gone up and is fixed with arc (3) by spacing rivet (4), by the upper-lower position variation locking cylindrical object (2) of spacing rivet (4) elongated hole (5) in arc (3).
2. arc locking linkage according to claim 1, it is characterized in that: have the opening that is slightly larger than cylindrical object (2) diameter on the described hook-type plate (1), its opening degree of depth approaches cylindrical object (2 diameter.
3. arc locking linkage according to claim 1 is characterized in that: have the elongated hole (5) more than 2 on the described arc (3).
4. arc according to claim 1 locking linkage is characterized in that: described arc (3) is with after hook-type plate (1) is connected, and limit of its close hook-type plate (1) opening one side is curved.
5. arc locking linkage according to claim 1, it is characterized in that: arc (3) and hook-type plate (1) are linked together by spacing rivet (4), when spacing rivet (4) finish riveting fixed after, it is exposed to the thickness that nail body length outside the hook-type plate (1) is slightly larger than arc (3).
