Abstract
The utility model discloses a connecting screw bolt for a furniture connector, which aims at solving the problems that the cross sections of the joints of the neck parts and the head parts and the rod parts of the existing connecting screw rods change suddenly, the stress is easy to concentrate and the connecting screw rods are twisted off or snapped. The connecting screw bolt for a furniture connector comprises a head part, a neck part, a rod part and a thread part, wherein, the joint of one end of the neck part and the head part is connected by a smooth transition curve, and the joint of the other end of the neck part and the rod part is connected by a smooth transition curve. The smooth transition curve of the joint of the neck part and the head part of the connecting screw bolt for a furniture connector is matched with the shape of the corresponding position of a cold forging processing die. The smooth transition curve of the joint of the neck part and the rod part of the connecting screw bolt for a furniture connector is matched with the shape of the corresponding position of the cold forging processing die. The mechanical strength of the improved connecting screw bolt for a furniture connector is improved obviously, and the utility model can be well applied for the connection of the furniture.
Description
Technical field
The utility model belongs to the furniture connection set, is specifically related to the improvement to the connecting screw rod in a kind of furniture connection set.
Background technique
In being connected of the transverse slat of furniture and stringer board, a kind of eccentric disc that comprises is arranged, connecting screw rod, the connection set that the plastic cement nut is formed, also claim three-in-one assembly parts, when this furniture connection set uses, at first on longitudinal plate, make a call to a transverse holes, imbed a plastic cement nut that mates with connecting thread, and with in the connecting screw rod connection, as the screw rod end is the wood snail line, then need not the plastic cement nut, then on horizontal plate, each makes a call to the vertical hole and the transverse holes that interconnect, inserts eccentric disc in vertical hole, and transverse holes stretches through for connecting screw rod, the head of connecting screw rod is buckled in the eccentric grove of eccentric disc, can finishes dismounting with screw-driver turn eccentric disc.Connecting screw rod in the above-mentioned connection set, owing to be subjected to the restriction of process conditions, normally make with the metal bar cutting, in the two ends of connecting screw rod neck and the junction of head and bar portion, changes of section is unexpected, be easy to generate stress and concentrate, when reality was used, the situation that connecting screw rod is twisted off or breaks happened occasionally.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, the connecting screw rod of the furniture connection set that mechanical strength is high.
A kind of connecting screw rod of furniture connection set comprises head, neck, bar portion and screw section, and neck one end and the junction of head are that slick and sly transition curve is connected, and the neck the other end and the junction of rod member are that the transition curve of slyness is connected.
The rounding off curve of connecting screw rod neck and head junction is to coincide with the shape of Cold Forging mould corresponding position.
The rounding off curve of connecting screw rod neck and bar portion junction is to coincide with the shape of Cold Forging mould corresponding position.
The beneficial effects of the utility model are as follows:
In the two ends of connecting screw rod neck and the junction of head and bar portion, adopt slick and sly transition curve to connect, can improve problem of stress concentration greatly; When being cold forging, the rounding off curve that is adopted produces convenient processing and manufacture by mold shape; The method that adopts cold forging to make makes metal surface produce flow harden, and the metal compaction degree increases, and mechanical strength obviously improves.

Embodiment
Be described in further detail the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, connecting screw rod comprises head 1, neck 2, bar portion 3 and screw section 4, neck 2 and the junction of head 1 are that the transition curve of the slyness that produces of Cold Forging is connected, and neck 2 and the junction of bar portion 3 are that the transition curve of the slyness of Cold Forging generation is connected.Be processed with cross recess on the connecting screw rod head 1, the screw thread of screw section 4 is used for being connected with the plastic cement nut.
Connecting screw rod as shown in Figure 2 is to make with the metal bar cutting, comprises head 5, neck 6, bar portion 7 and screw section 8, and in the two ends of connecting screw rod neck 6 and the junction of head 5 and bar portion 7, changes of section is unexpected, is easy to generate stress and concentrates.Be processed with cross recess on the connecting screw rod head 5, the screw thread of screw section 8 is used for being connected with the plastic cement nut.
The another kind of mode of execution of connecting screw rod as shown in Figure 3, comprise head 9, neck 10, bar portion 11 and screw section 13, neck 10 and the junction of head 9 are that the transition curve of the slyness that produces of cold forging is connected, and neck 10 and the junction of bar portion 11 are that the transition curve of the slyness of cold forging generation is connected.Increase is provided with a few limit baffle rings 12 in bar portion 11, and limit baffle ring 12 is further processing generation in bar portion 11.Screw section 13 is provided with the wood snail line, and the wood snail line can directly screw in sheet material.Be processed with cross recess on the connecting screw rod head 9.
As shown in Figure 5, when the furniture connection set uses, at first on longitudinal plate 16, make a call to a transverse holes, imbed a plastic cement nut that mates with the connecting screw rod screw thread, and with in the connecting screw rod connection, as the screw rod end is the wood snail line, then need not the plastic cement nut, then on horizontal plate 17, each makes a call to the vertical hole and the transverse holes that interconnect, inserts eccentric disc 14 in vertical hole, and transverse holes stretches through for connecting screw rod, the head of connecting screw rod is buckled in 15 li of the eccentric groves of eccentric disc, can finishes dismounting with screw-driver turn eccentric disc.
Improved connecting screw rod can well be applied to the connection of furniture, avoids and reduces the generation that twists off with tensile phenomenon.
