Description
Technical Field
The utility model relates to a connecting piece technical field, concretely relates to can centering locking screw structure that takes off for installation of computer upper cabinet product.
Background
At present, the front panel of the upper cabinet product and the cabinet are mainly installed in two modes, one mode is an installation mode using crown screws, namely the screws penetrate through holes on two sides of the front panel to be connected with the cabinet, and the screw through holes are waist holes, so that the installation mode has the advantage that the problem that the centers of the through holes and the threaded holes cannot be overlapped due to installation or processing errors can be solved; the defects are that after the screw is disassembled, the hanging connection between the screw and the panel can not be ensured, the screw is easy to lose, and the secondary assembly is inconvenient. The other installation mode is to use a loose and non-falling screw, and a rivet nut part of the loose and non-falling screw needs to be riveted on the front panel to ensure the hanging connection of the loose and non-falling screw and the panel, and the installation mode has the advantages that when the screw is disassembled, the screw can be hung on the panel, and the secondary assembly is more convenient; the shortcoming is that when leading to via hole and screw hole center can't coincide because of processing or assembly error, the unable screw in screw hole of screw is not come loose for one kind condition, can't satisfy the installation of last cabinet product fixed, and there is certain angle slope when another kind condition is the screw in, and the screw is easy to be lost efficacy, consolidates unreliable.
Aiming at the second installation mode, the problem that the centers of the via holes and the threaded holes cannot coincide is solved, the installation structure of the floating nut is added on the cabinet by a commonly adopted method, the structure needs larger installation space, the processing difficulty is relatively larger, so when the installation space is limited or the processing is difficult, the threaded holes are directly added at the positions of cabinet products installed on the two sides of the cabinet by adopting a tapping mode, and the problem that the cabinet products cannot be installed and reinforced reliably exists at the moment.
Disclosure of Invention
The utility model discloses an overcome not enough of above technique, provide one kind and still can be easy to assemble when screw hole and through-hole disalignment be used for the computer to go up the locking screw structure that takes off of adjustable heart of cabinet product installation.
The utility model overcomes the technical scheme that its technical problem adopted is:
a center-adjustable anti-loosening screw structure, comprising:
the bottom center of the expanding rivet nut is provided with a groove II, the upper center of the expanding rivet nut is provided with a threaded hole, and the tail end of the threaded hole is communicated with the groove II;
the polished rod is inserted into the threaded hole in a sliding mode, the head end of the polished rod is provided with a bolt head, the tail end of the polished rod is coaxially provided with a threaded section, the threaded section is matched with the threaded hole, and the upper end of the threaded section is located in the groove II;
the spring is sleeved on the polished rod, the upper end of the spring is contacted with the bolt head, and the lower end of the spring is contacted with the expansion rivet nut; and
the plurality of yielding holes are uniformly arranged on the periphery of the threaded hole at intervals along the circumferential direction, the cross section of each yielding hole is semicircular, and the inner diameter of each semicircular yielding hole is matched with the outer diameter of the polished rod.
For anti-skid, several bulges are set at intervals along the circumference of bolt head.
For convenient installation, the head end of the bolt head is provided with a straight groove.
In order to improve the attractiveness and the safety, the head end of the expansion riveting nut is provided with a groove I, the lower end of the spring is inserted into the groove I, and the upper end of the threaded hole is communicated with the groove I.
The utility model has the advantages that: when installing the front panel on the rack, with the screw thread section line with in the screw hole, until the screw thread section passes from the screw hole, it is located recess II, polished rod activity cartridge this moment in the screw hole, with the screw thread section pass the mounting hole of front panel after the screw thread section closes in the screw hole of rack soon, can this moment through rotatory bolt head, the screw thread section closes in the rack soon after the spring compression to make the internal thread between screw thread section and the screw closely contact under the spring force, thereby prevent to loosen. If its axis is cheap when the tapping for the screw hole in the rack, its mounting hole disalignment with the front panel promptly, the polished rod can be to the 7 offsets of the hole of stepping down that correspond this moment to still can ensure that the screw thread section screws in the screw, realized the function of automatic aligning.

Detailed Description
The present invention will be further described with reference to fig. 1 to 4.
A center-adjustable anti-loosening screw structure, comprising: the center of the bottom of the expanding rivet nut 2 is provided with a groove II 10, the center of the upper end of the expanding rivet nut is provided with a threaded hole 9, and the tail end of the threaded hole 9 is communicated with the groove II 10; the polished rod 7 is inserted into the threaded hole 9 in a sliding mode, the head end of the polished rod 7 is provided with a bolt head 4, the tail end of the polished rod 7 is coaxially provided with a threaded section 6, the threaded section 6 is matched with the threaded hole 9, and the upper end of the threaded section 6 is located in the groove II 10; the spring 3 is sleeved on the polished rod 7, the upper end of the spring is contacted with the bolt head 4, and the lower end of the spring is contacted with the expanding rivet nut 2; and the plurality of yielding holes 11 are uniformly arranged on the periphery of the threaded hole 9 at intervals along the circumferential direction, the cross section of each yielding hole 11 is semicircular, and the inner diameter of each semicircular yielding hole 11 is matched with the outer diameter of the polished rod 7.
