Abstract
A connection bolt for a concealed electric appliance junction box is used for solving the problems that the similar bolts are difficult to find or the connection bolt is difficult to be locked caused by the slippage of the tail end of the bolt in the case of aligning bolt hole on the connection plate or rotating the bolt, and the panel installation efficiency is affected. The technical scheme is that the connection bolt is composed of a bolt head part and a bolt shank part, wherein a screwdriver coordinated slot is arranged on the bolt head part, external screw thread is arranged on the bolt shank part, characterized in that the tail end of the bolt shank part is provided with a smooth shank section with the diameter less than or equal to the inner diameter of the external screw thread, the length of 1 to 5 mm, the shank inclination of 0 to 40 DEG. The utility model can greatly reduce the locking difficulty of the connection bolt, and greatly improve the panel installation efficiency.
Description
Technical field
The utility model belongs to civil electric appliance electricity consumption connector, specifically is meant a kind of attachment screw of concealed electrical appliance junction box.
Background technique
The present concealed electrical appliance junction box that generally uses, be to constitute by box body that is hidden in the connection the held panel lead in the wall and the dress panel that is provided with connector assembly, switch base and so on thereon, between the two by the attachment screw use that fuses, wherein the screw that passes on the connecting sheet in the nail Kong Houyu box body on the panel of attachment screw is made screw-thread fit, and panel is fixed tightly on the box body.Because the connecting sheet in the box body generally has certain distance apart from the nail hole of panel, and box body and panel all are that perpendicular putting is contained on the wall, be that attachment screw is horizontally to pass the nail hole of panel and the screw of connecting sheet is made screw-thread fit, be to hold on the other hand panel, another hand to hold screwdriver and head on attachment screw and rotate the centering screw during installation, so the screw tail end often is difficult to find or align the screw on the connecting sheet, aligned also and can when screw turns, slide partially by the screw tail end, cause the difficulty of locking attachment screw very big, have influence on the panel installation efficiency.
Summary of the invention
For the attachment screw that overcomes existing similar concealed electrical appliance junction box exist be difficult to find or when aligning on the connecting sheet screw or screw turns the screw tail end partially sliding, cause the difficulty of locking attachment screw big, influence the defective of panel installation efficiency, the purpose of this utility model provides a kind of improved attachment screw that is exclusively used in the concealed electrical appliance junction box, can overcome the defective of prior art.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of attachment screw of concealed electrical appliance junction box, constitute by screw head and screw rod portion, the screwdriver mating groove is arranged on the screw head, in the screw rod portion outside thread is arranged, it is characterized in that: the tail end of screw rod portion has the smooth shaft section of a diameter smaller or equal to core diameter, the length of smooth shaft section is 1～5 millimeter, and the pole face gradient of smooth shaft section is 0～40 °.
The total length of the attachment screw of technique scheme is generally 18～40 millimeters, and the nominal diameter of attachment screw is generally 3～5 millimeters.
The called torulopsis of technique scheme is meant that the bar section surface does not have screw thread.The so-called pole face gradient of technique scheme is meant when process smooth shaft section medial axis, a plane, the intersection of plane and smooth shaft section side and the angle of smooth shaft section medial axis.
The optimum length of the smooth shaft section of technique scheme is 2.5～3.5 millimeters; The best pole face gradient of smooth shaft section is 0～10 °.
The beneficial effects of the utility model: because the tail end of screw rod portion has the smooth shaft section of a diameter smaller or equal to core diameter, the length of smooth shaft section is 1～5 millimeter, the pole face gradient of smooth shaft section is 0～40 °, so when panel is installed, can be earlier with the screw of hand with the tail end centering connecting sheet of screw rod portion, smooth shaft section with tail end injects screw again, the tail end of screw rod portion just is temporarily fixed on the screw, at this moment the people is installed just can holds panel on the other hand, another hand is held the screwdriver screw that is rotationally connected, attachment screw can advance screw by very smooth lock, the rotation process screw tail end connecting sheet screw that can not slip away, thereby can reduce the locking difficulty of attachment screw greatly, and improve the panel installation efficiency greatly.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a schematic perspective view.
Fig. 2 is the perspective exploded view that Fig. 1 is applied in a kind of embodiment on the concealed electrical appliance junction box, and wherein the concealed electrical appliance junction box is done horizontally-arranged placement.
Among the figure: 1, screw head; 2, screw rod portion; 3, screwdriver mating groove; 4, outside thread; 5, smooth shaft section; 6, box body; 7, panel; 8, attachment screw; 9, nail hole; 10, connecting sheet; 11, screw; 12, attachment screw; 13, connecting sheet; 14, screw.
Embodiment
With reference to Fig. 1, the attachment screw of this concealed electrical appliance junction box, constitute by screw head 1 and screw rod portion 2, screwdriver mating groove 3 is arranged on the screw head 1, outside thread 4 is arranged in the screw rod portion 2, it is characterized in that: the tail end of screw rod portion 2 has the smooth shaft section 5 of a diameter smaller or equal to core diameter, and the length of smooth shaft section is about 3 millimeters, and the pole face gradient of smooth shaft section is 0～10 °.In addition, the overall length that attachment screw contains smooth shaft section 5 is about 35 centimetres, and the nominal diameter of attachment screw is 4 millimeters.
With reference to Fig. 2, when the concealed electrical appliance junction box is installed, after box body 6 dresses are ensconced in the wall, on the other hand switch panel 7 is covered just on box body 6 oral areas, after another hand passes the tail end of attachment screw 8 nail hole 9 on the panel 7 earlier, screw 11 on the connecting sheet 10 in the centering box body 6, the smooth shaft section 5 of attachment screw 8 tail ends is injected screw 11, attachment screw 8 tail ends just are temporarily fixed on the screw 11, the former hand of taking attachment screw just can be picked up the screwdriver screw 8 that is rotationally connected, the just very smooth lock of attachment screw 11 advances screw 11, the screw 8 process screw tail ends that the are rotationally connected screw 11 that can not slip away.After like this another attachment screw 12 locks being advanced the screw 14 on the connecting sheet 13, panel 7 just is fixed tightly on the box body 6.
