Abstract
The invention discloses a panel and cabinet connecting structure with sunk screws. The panel and cabinet connecting structure with the sunk screws comprises a panel, a cabinet, a first sunk screw, a mounting nut and a cavity, wherein the cabinet clings to the panel; the cavity clings to the lower surface of the cabinet; nuts are inlaid in two ends of the cavity; second sunk screws penetrate in the cabinet and are connected with the nuts of the two ends of the cavity; a mounting hole is formed in the middle of the cavity; a lock washer and a mounting nut are placed in the mounting hole; the first sunk screw sequentially penetrates in the panel, the cabinet and the lock washer and is in threaded connection with the mounting nut; a gap by which the mounting precision can be adjusted is reserved between the first sunk screw and the cabinet; and another gap by which the mounting precision can be adjusted is reserved between the mounting nut and the cavity. The panel and cabinet connecting structure with the sunk screws is convenient and easy to assemble and operate; installation of the panel and installation of the cabinet are guaranteed; the first sunk screw is accurately aligned with the sunk screw mounting hole in the panel; and the assembly quality of a product is improved.
Description
Technical field
The present invention relates to the fastening structure in mechanical field, be specifically related to a kind of panel and the cabinet connection structure that use sunk screw.
Background technique
In mechanical erection process, panel and cabinet are fastened together by the normal sunk screw that uses.Original linkage structure is that panel is connected with the mounting nuts be welded on cabinet by multiple sunk screw, and during practical operation, because mounting nuts welding contraction makes pitch-row occur deviation, panel makes screw mounting hole apart from occurring tolerance because processing.
When sunk screw is installed, because mounting nuts cannot move, make tapped hole center and panel screwing head counterbore center can not accurate centering, countersunk head bias, screw head evagination when causing sunk screw to install, cause screw head monolateral stressed, can not fasteningly put in place, quality of product cannot be guaranteed, and when the number of sunk screw is more, this shortcoming is more obvious.
Summary of the invention
The panel of original use sunk screw and cabinet connection structure, panel is connected fastening by sunk screw with the mounting nuts be welded on cabinet, easily cause that countersunk head is eccentric, screw head evagination, cause screw countersunk head monolateral stressed, can not fasteningly put in place, quality of product cannot be guaranteed.The object of the invention is to, for above-mentioned the deficiencies in the prior art, propose a kind of panel and cabinet connection structure of use sunk screw of improvement.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of panel and cabinet connection structure using sunk screw, comprise panel, with the cabinet of panel attachment, the first sunk screw and mounting nuts, also comprise the cavity of fitting with cabinet lower surface, described cavity two ends are embedded with nut, described second sunk screw is connected with the nut at cavity two ends through described cabinet, has mounting hole, be placed with lock washer and mounting nuts in described mounting hole in the middle of described cavity, lock washer has locking effect, can guarantee that panel is connected with cabinet fastening.Described first sunk screw is fastening through being connected with mounting nuts after panel, cabinet, lock washer successively, leave the gap of adjustable installation precision between described first sunk screw and cabinet, between described mounting nuts and cavity, leave the gap of adjustable installation precision.Gap suitably can adjust according to machining tolerance.The first sunk screw on panel is equipped with a cavity separately, installs with sunk screw mounting hole on panel for benchmark, by mobile mounting nuts, the accurate centering of sunk screw mounting hole realized on the first sunk screw and panel.
As a kind of optimal way, described cavity is moulding, and the two ends of described cavity are embedded with injection moulding nut.
As a kind of optimal way, described lock washer is wave spring washer.
Compared with original technology, the present invention use the panel of sunk screw and cabinet connection structure assembly operation convenient and simple, the accurate centering of sunk screw mounting hole when can not only ensure that panel and cabinet are installed on the first sunk screw and panel, the wave spring washer with locking effect can guarantee that the first sunk screw counter plate is connected fastening with cabinet, improves the quality of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Wherein, 1 is panel, and 2 is cabinet, and 3 is cavity, and 4 and 5 is injection moulding nut, and 6 and 7 is the second sunk screw, and 8 is wave spring washer, and 9 is mounting nuts, and 10 is the first sunk screw, and 11 is mounting hole.
Embodiment
As shown in Figure 1, one embodiment of the invention comprise panel 1, the cabinet 2 of fitting with panel 1, first sunk screw 10 and mounting nuts 9, also comprise the cavity 3 of fitting with cabinet 2 lower surface, described cavity 3 is moulding, the two ends of described cavity 3 are embedded with injection moulding nut 4, 5, described second sunk screw 6, 7 are connected with the injection moulding nut at described cavity 3 two ends through described cabinet 2, mounting hole 11 is had in the middle of described cavity 3, wave spring washer 8 and mounting nuts 9 is placed with in described mounting hole 11, wave spring washer 8 has locking effect, guarantee that panel 1 is connected fastening with cabinet 2.Described first sunk screw 10 is connected with mounting nuts 9 through after panel 1, cabinet 2, wave spring washer 8 successively, leave the gap of adjustable installation precision between described first sunk screw 10 and cabinet 2, between described mounting nuts 9 and cavity 3, leave the gap of adjustable installation precision.Be fitted through mobile mounting nuts 9, realize the accurate centering of sunk screw mounting hole on the first sunk screw 10 and panel 1.
