Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
As shown in fig. 1, 2 and 3, the locking member for connecting a bracket according to an embodiment of the present invention is used for connecting a vertical rod and an inclined strut in scaffold building. Which comprises a lock body 1 and a fastener 2. Utilize latch fitting body 1 and fastener 2 to connect bracing and pole setting. The utility model discloses simple structure, easy operation is convenient, has overcome prior art and has produced the great problem of stress concentration ratio in the pole setting with bracing beading, has improved construction speed and security, but the wide application is connected in scaffold frame pole setting and bracing for the building.
The latch fitting body 1 comprises a first connecting part 11 and a sliding groove 12, the sliding groove 12 is connected with one end of the first connecting part 11, the vertical rod is connected with the other end of the first connecting part 11, and a through hole 13 is formed in the first connecting part 11. In practical implementation, in order to increase the stability and safety of the latch body 1, the first connecting portion 11 and the sliding groove 12 are integrally formed, and the strength is relatively high.
The fastener 2 includes a second connecting portion 21 and a third connecting portion 22, the second connecting portion 21 is connected to the sliding groove 12, the third connecting portion 22 is connected to the through hole 13, and a locking portion 23 is provided at an end of the third connecting portion 22. Also, in order to increase the stability and safety of the fastening device 2, the second connecting portion 21 and the third connecting portion 22 are integrally formed, so that the structural strength of the fastening device 2 is relatively stable.
In practical application, the sliding groove 12 is a regular or irregular groove hole. The whole structure is simpler. More preferably, the sliding groove 12 is provided as a rectangular groove hole, a circular groove hole, or an elliptical groove hole. The structures are common structures and are low in manufacturing cost.
The connecting of the vertical rod and the inclined strut needs to bear load, and in order to eliminate partial stress and increase the stability of the locking piece, a notch 120 can be arranged on the sliding groove 12. The arrangement of the notch 120 structure can save part of materials, thereby saving the cost; but also can eliminate partial stress generated by the vertical rods and the inclined struts due to load bearing.
The locking portion 23 is a first pin hole. After the locking portion 23 passes through the through-hole 13, it is pinned into the first pin hole so that the locking portion 23 does not fall out of the through-hole 13. The second connecting portion 21 is provided with a second pin hole 24, and after the second connecting portion 21 passes through the slide groove 12, it can be pinned into the second pin hole 24 so that the second connecting portion 21 does not fall out of the slide groove 12. The structure of the first pin hole and the second pin hole 24 is adopted, so that the structure is simple and convenient, the cost is low, and the operation is simple and convenient.
When the utility model is implemented, the mounting hole of the end part of the inclined strut is sleeved on the first connecting part 11 in the locking piece body 1, and then the end part of the first connecting part 11 is welded or matched with other accessories to be connected to the vertical rod. In order to make the connection between the first connecting portion 11 and the vertical rod more tight, the connection between the first connecting portion 11 and the vertical rod is an arc surface. Like this, the laminating is inseparabler when first connecting portion 11 is connected with the pole setting, and the operator of also being convenient for operates, and the operator is when the welding, is difficult to have the problem of rosin joint, and the welded comparison is abundant.
After the first connecting portion 11 and the vertical rod are connected, the operator only needs to insert the second connecting portion 21 of the fastener 2 into the sliding groove 12 and pin-connect it into the second pin hole 24, so that the second connecting portion 21 does not fall out of the sliding groove 12. Then, the operator only needs to insert the end of the third connecting portion 22 into the through hole 13 of the first connecting portion 11, and then the fastening member 2 is directly caught on the locker body 1 due to the gravity. Finally, the operator again pins into the first pin hole so that the locking portion 23 does not fall out of the through hole 13. At this point, the connection between the uprights and the diagonal braces is completed. The integral structure is simple, the operation is simple and convenient, and the problem that the stress concentration generated by directly welding the inclined strut on the vertical rod in the prior art is large is solved. In addition, when the fastener is detached, the fastener 2 can be taken out simply and conveniently only by detaching the two pins.
Latch fitting, overall structure is simple, convenient operation, connection safety and stability, and improved construction speed and security.
