Abstract
The utility model belongs to field of fixtures, it is intended to provide a kind of pcb board plastic buckle installs fixture of stable structure, its drip irrigation device includes bottom plate, the bottom plate is equipped with limit plate, the vertex of the limit plate is equipped with several positioning pins, is rotatablely connected between the positioning pin and limit plate, and the limit plate is equipped with pin hole, the positioning pin is arranged in pin hole, and pin hole inner wall is equipped with the conflict bar contacted on positioning pin.By using above-mentioned technical proposal, in use, if clamped part contradicts on positioning pin, thrust is produced to positioning pin, the conflict bar of pin hole inner wall has a degree of limit power to positioning pin, can reduce a possibility that positioning pin collides rear-inclined by extraneous part.If finding relative displacement between clamped part and positioning pin simultaneously, the turntable of positioning pin can be effectively reduced a possibility that frictional resistance bring pushes away oblique positioning pin.
Description
Technical field
The utility model relates to fixture, in particular to a kind of pcb board plastic buckle installs fixture.
Background technique
Fixture is a kind of common Workshop Production auxiliary tool, and in actual use, the two o'clock that fixture considers is general
It is the stability of itself and whether requirement can be reached to the limit power of clamped object.
Currently, common fixture generally includes a pedestal, the limiting component for clamping components is set on pedestal,
Or several rod pieces are drawn on limiting component, benchmark used when as clamping.
But since rod piece is often elongate, when by external force, it is easy to happen inclination, therefore can be to clamping effect
It influences.
Utility model content
The purpose of the utility model is to provide a kind of pcb board plastic buckle installs fixtures, have the bar drawn from fixture
Part is not easy the advantages of shaking.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of pcb board plastic buckle installs fixture, including bottom plate, the bottom plate are equipped with limit plate, the limit plate
Vertex is equipped with several positioning pins, is rotatablely connected between the positioning pin and limit plate, and the limit plate is equipped with pin hole, described
Positioning pin is arranged in pin hole, and pin hole inner wall is equipped with the conflict bar contacted on positioning pin.
By using above-mentioned technical proposal, in use, if clamped part contradicts on positioning pin, to positioning
Pin produces thrust, and the conflict bar of pin hole inner wall has a degree of limit power to positioning pin, it is extraneous to can reduce positioning pin
Part collides a possibility that rear-inclined.If relative displacement is found between clamped part and positioning pin simultaneously, positioning pin can
Rotational structure can be effectively reduced a possibility that frictional resistance bring pushes away oblique positioning pin.
Further, the diameter of the pin hole is greater than the cross-sectional diameter of positioning pin, sets between the pin hole and positioning pin
There is the bearing for driving positioning pin to rotate.
Further, the outer wall of the bearing and pin hole inner wall are connected, the inner wall of the bearing and the outer circle table of positioning pin
Face is connected.
By using above-mentioned technical proposal, the volume of bearing is big and stablizes, and for positioning pin when by external force, bearing is can
A possibility that under the premise of driving positioning pin rotation, certain limit power is also generated to positioning pin, reduces positioning pin inclination.
Further, the conflict bar is drawn from pin hole inner wall, and the conflict bar is fallen on the tangent line of positioning pin.
By using above-mentioned technical proposal, contradict bar and the tangent setting of positioning pin, can during positioning pin rotates,
Frictional resistance is reduced in a manner of line contact.
Further, the conflict bar is at least provided with two groups, and for every group of conflict bar at least provided with two, two conflict bars are parallel
Setting, and it is located at the two sides of positioning pin.
Further, two groups of conflict bars are located at bearing vertical direction two sides.
Further, vertical a lower height of one group of conflict bar is affixed with bearing.
By using above-mentioned technical proposal, limit power suffered by positioning pin is issued from multiple directions, is conducive to
Maintain the stability of positioning pin.
Detailed description of the invention
Fig. 1 is for embodying fixture overall structure diagram；
Fig. 2 is the relative positional relationship schematic diagram for embodying positioning pin and limit plate；
Fig. 3 is the positional structure schematic diagram for embodying bearing；
Fig. 4 is the partial sectional view for embodying limit plate.
In figure, 1, bottom plate；2, limit plate；3, positioning pin；4, pin hole；5, bar is contradicted；6, bearing.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and
"outside" refers respectively to the direction towards or away from geometric center of specific component.
A kind of pcb board plastic buckle installs fixture, including bottom plate 1, the bottom plate 1 are equipped with limit plate 2, the limit plate
2 vertex is equipped with several positioning pins 3, is rotatablely connected between positioning pin 3 and limit plate 2, and the limit plate 2 is equipped with pin hole 4,
The positioning pin 3 is arranged in pin hole 4, and 4 inner wall of pin hole is equipped with the conflict bar 5 contacted on positioning pin 3.
The diameter of the pin hole 4 is greater than the cross-sectional diameter of positioning pin 3, is equipped with and is used between the pin hole 4 and positioning pin 3
The bearing 6 for driving positioning pin 3 to rotate.
The outer wall and 4 inner wall of pin hole of the bearing 6 are connected, and the inner wall of the bearing 6 and the outer round surface of positioning pin 3 are solid
Even.
The conflict bar 5 is drawn from 4 inner wall of pin hole, and the conflict bar 5 is fallen on the tangent line of positioning pin 3.
The conflict bar 5 is at least provided with two groups, and at least provided with two, two conflict bars 5 are arranged in parallel every group of conflict bar 5,
And it is located at the two sides of positioning pin 3.
Two groups of conflict bars 5 are located at 6 vertical direction two sides of bearing.
