Abstract
The utility model relates to a clamping slot type self-locking nut which comprises a trapezoid step at the bottom, wherein the trapezoid step is provided with a connecting head. The connecting head is provided with screwed holes. A rivet pressing clamping slot is arranged at the bottom of the trapezoid step. At least two screwed holes are arranged. A screw thread damaging device is arranged on the screw thread of each screwed hole. The screw thread damaging device is structured in such a way that at least one groove for damaging the screw thread is arranged towards the screw thread at the side of the screwed holes. A first connecting clamping slot is arranged at the intersection of the trapezoid step and the connecting head. The screwed holes are arranged horizontally; the screwed holes are arranged vertically and a second connecting clamping groove is arranged between adjacent screwed holes. With the adoption of the structure, according to the clamping slot type self-locking nut connected in a circuit board and a communication cabinet, one nut can be connected with a plurality of parts in the horizontal or vertical direction so as to further reduce the size and the occupied space of the circuit board, so that the clamping slot type self-locking nut can be conveniently used by small equipment. Bumps of internal threads that damage the screw threads can prevent parts from falling and keep the equipment safe.
Description
Technical field
The utility model relates to a kind of nut in the mechanical industry, especially relates to a kind of groove-fastening type self-locking nut.
Background technique
At present, a kind of self-clinching nut that is used for electron trade is arranged on the market, mainly be riveted in circuit board and the communication cabinet and be used to be connected other parts; As shown in Figure 1, this nut of the prior art after riveted joint, just can only connect a part, and the draw-in groove of its neck is that circular arc is excessive because have only a tapped hole on it, is not easy the clamping part.And, this nut when in use, the part of connection drops in nut easily, causes the fault of machine.
Summary of the invention
The utility model technical problem to be solved provides a kind of groove-fastening type self-locking nut of can a plurality of parts of clamping and being not easy to drop.
The utility model solves the technological scheme that its technical problem adopted: a kind of groove-fastening type self-locking nut; Comprise the terraced steps of bottom, terraced steps is provided with the connection head, connects head and is provided with tapped hole; The bottom of terraced steps is provided with the draw-in groove that presses, at least two of described tapped holes.
For the part that prevents to connect drops in nut, the screw thread place of described tapped hole is provided with the destruction screw device; Be provided with the groove that is used to destroy screw thread and at least one in the one side direction screw thread of further described tapped hole, further, described groove is three.
Part connects for ease, and described terraced steps is provided with first with the intersection that is connected head and connects draw-in groove.
Part carries out horizontally for ease, and described tapped hole is horizontal.
Part is vertically arranged for ease, and described tapped hole is vertically arranged, and between adjacent tapped hole, is provided with second and connects draw-in groove.
The beneficial effect of the utility model is: adopt after the said structure; Be connected circuit board and can on level or vertical direction, be connected a plurality of parts by a nut with the interior groove-fastening type self-locking nut of communication cabinet; The size that can further reduce circuit board with take up room, make things convenient for compact apparatus to use; Adopt the groove that destroys nut inner thread, can prevent that part from therefrom dropping, keep the Security of equipment.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a kind of structural representation of the utility model groove-fastening type nut;
Fig. 3 is the another kind of structural representation of the utility model groove-fastening type nut.
Among the figure: 1, connect head; 2, tapped hole; 3, terraced steps; 4, the draw-in groove that presses; 5, groove; 6, second connects draw-in groove; 7, first connects draw-in groove.
Embodiment
A kind of as shown in Figures 2 and 3 groove-fastening type self-locking nut, the terraced steps 3 bottom comprising, terraced steps 3 are provided with and connect head 1, connect head 1 and are provided with tapped hole 2, and the bottom of terraced steps 3 is provided with the draw-in groove 4 that presses, 2 at least two of described tapped holes; The screw thread place of described tapped hole 2 is provided with the destruction screw device; Described destruction screw device is used to destroy the groove 5 of screw thread and is three in a side direction screw thread of tapped hole, establishing; Described terraced steps 3 is provided with first with the intersection that is connected head 1 and connects draw-in groove 7; Described tapped hole 2 horizontal (as shown in Figure 2); Described tapped hole 2 is vertically arranged, and between adjacent tapped hole 2, is provided with second and connects draw-in groove 6 (as shown in Figure 3).
The groove-fastening type self-locking nut presses draw-in groove 4 riveted joints onboard through the bottom; Its two or more tapped holes 2 that connect on the head 1 can connect a plurality of parts; And when tapped hole 2 is vertically arranged, have second to connect draw-in groove 6 between the two adjacent tapped holes 2, the concentrating of more convenient a plurality of parts; Make things convenient for device miniaturization, lighting; Because three grooves 5 that destroy screw thread are arranged on it, when part connects, destroyed the screw thread on the part, it can not be broken away from from nut, ensured the Security of equipment.
