The utility model is characterized in that both sides of the matching part of the hole (4) and the longitudinal end of the T-shaped structure of the fastening cover are planes (6), and both sides of the planes (6) are provided with reinforcing ribs (7).
Description
The utility model relates to a kind of parts of the connection fastener that is used for being coupled to each other between scaffold member, it is the fastening seat of scaffold clasp, which is provided with and hold tightly circular arc, be provided with the union end that connects with fastening cover at the two ends of holding circular arc tightly, wherein an end has the hole that connects with fastening cover, and its other end has places the fixedly pit of the bolt head of fastening cover and the hole of matching with bolt.
The fastening seat of China's utility model patent 92244646.6 disclosed scaffold connection fasteners, itself and the joining end of fastening seat are provided with the hole of the end that can vertically put into fastening cover and can laterally settle the cavity of fastening cover end.Need the deficiency of riveting in the existing technology in the member production though this patent has overcome, solved easily the change problem of fastener lid, cause in the product Foundry Production certain difficulty is arranged because this end of fastening is provided with cavity with seat.
The purpose of this utility model provides a kind of prior art deficiency that overcomes, and makes things convenient for the fastening seat of Foundry Production.
The purpose of this utility model realizes with following measure:
With the both sides at hole in the device that fastening cover connects and the horizontal end place of matching of fastening cover T type structure is the plane, is provided with reinforcing rib on the both sides on plane.
The utility model can also be realized with following measure:
The L type is made in the hole with in the joining device of fastening cover on the fastening seat.
The breach that has the II type is established in match with bolt on the fastening seat outer end in hole.
Whole fastening seat is for to be in a member of holding circular arc tightly that has two quadrature settings on the whole, and holding tightly at each has joining two union ends of fastening cover respectively on the circular arc.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is an elevation of the present utility model;
Accompanying drawing 2 is the left view of Fig. 1;
Accompanying drawing 3 is the right view of Fig. 1;
Accompanying drawing 4 is that the A-A of Fig. 1 is to sectional view;
Accompanying drawing 5 is the plane interactional schematic diagram other with the hole of matching of the T type structure on the fastening cover;
Accompanying drawing 6 is that the B-B of Fig. 5 is to sectional view.
Schematically drawn in Fig. 5 among the above-mentioned figure the limiting member, other figure all do not express limiting member.
By having and the joining union end of fastening cover (2) and (3) at the two ends of holding circular arc (1) tightly in Fig. 1 and the visible the utility model of other views.Wherein (3) end is provided with the pit (8) of placing the bolt end that is used for fixing fastening cover and the hole (5) of placing this bolt, the other end (2) is provided with the joining hole of T type structure (4) with fastening cover, hole (4) is plane (6) with the both sides at the horizontal end place of matching of fastening cover T type structure, and the both sides of (6) are provided with reinforcing rib (7) on the plane.Be the horizontal end of T type structure (10) that utilizes on plane (6) and the fastening cover in the utility model, see Fig. 5 and Fig. 6, points of tangency is a fulcrum, clamps scaffold member under the effect of fastening bolt.By Fig. 6 be also shown in the horizontal end (10) of the T type structure on the fastening cover can be along the hole length direction of (4), promptly the direction of arrow among the figure is done to adjust on a small quantity.
The hole (4) that is also shown in the utility model by Fig. 1 is the L type, should make the horizontal end of the vertical end length in L type hole (4) greater than the T type structure of fastening cover in the manufacturing of reality, makes the vertical end parts maximum size of corner's size in hole (4) greater than T type structure.Adopt such structure can guarantee that the T type structure covered is very easily in the patchhole (4) and be in normal installation site.For preventing to come off again after fastening cover from installing, can (4) locate to place a limiting member (11) in the hole, referring to Fig. 5, corner's width in hole (4) is reduced, make the T type structure of fastening cover can not rotate back into the position that comes off.
The outer end that hole of the present utility model (5) is located is provided with the breach (9) of II type, adopts this structure to make to be arranged in the bolt in hole (5) that a spot of oscillating quantity can be arranged outward, to make things convenient for the fastening of fastening cover.
Advantage of the present utility model is as follows:
1, because the utility model will change the plane structure of band reinforcing rib into the joining cavity structure of fastening cover in the prior art, improved the casting character of product, made operations such as follow-up sand removal, machine more convenient simultaneously.
2, structure of the present utility model can reduce the weight of product, shows through actual measurement, has under the condition of same intensity the gently about 10-20% of the comparable prior art of the utility model.
The outer end at the place, hole that 3, matches with bolt in the utility model is provided with the breach of II type, makes the bolt that is arranged in the hole that a spot of oscillating quantity can be arranged outward, can make things convenient for the fastening of fastening cover.
4, in use, the horizontal end of the T type structure on the fastening cover is tangent with the plane on side, the hole of matching, and be fulcrum with the point of contact, the horizontal end of T type structure can be made slight displacement along described plane simultaneously, position between the scaffold member of holding circular arc tightly and being fixed on fastening cover and the seat is adjusted, improve embracing and condition of fastener, improved the power of holding tightly.
Fig. 1 in the accompanying drawing also is an embodiment of the present utility model.This example is the scaffold member that is used for fixing quadrature, and what two quadrature settings were arranged on it holds circular arc (1) tightly, holds tightly at each to be respectively equipped with on the circular arc and joining two union ends of fastening cover (2) and (3).Be provided with T type structure joining L type hole (4) with fastening cover on (2) at end, hole (4) place that matches with the horizontal end of fastening cover T type structure, referring to Fig. 5,6, both sides be plane (6), the both sides of (6) are provided with reinforcing rib (7) on the plane.
