Abstract
The utility model discloses a kind of drawing-aid device, by drawing-aid device spring（1）, drawing-aid device steel ball（2）, drawing-aid device rotational pin（3）, drawing-aid device handle（4）, drawing-aid device fixed seat（5）Composition；Described drawing-aid device handle（4）Pass through drawing-aid device rotational pin（3）It is fixed on drawing-aid device fixed seat（5）On, it is possible to around the drawing-aid device rotational pin（3）In drawing-aid device fixed seat（5）Upper rotation；When drawing-aid device handle rotate in place, steel ball（2）Slide into the groove of drawing-aid device fixed seat（6）It is interior, so as to lock drawing-aid device handle（4）And prevent that it from vibrating and loosening with cabinet, described drawing-aid device fixed seat（5）It is arranged on when in use and pcb board（8）One piece of orthogonal installing plate（7）On, the utility model uses single fixing seat mounting structure, it is to avoid take the plug-in unit area of pcb board；The spring steel ball of drawing-aid device handle effectively can prevent handle from loosening simultaneously；And handle capable of being provides larger torque so that the plug of pcb board is more laborsaving.
Description
Technical field
The utility model is related in a kind of communications industry used drawing-aid device.
Background technology
Current existing drawing-aid device size is smaller, as shown in figure 1, when pcb board size is larger, drawing-aid device（10）With PCB
Plate（11）Size it is uncoordinated, firmly inconvenience causes contact engaging and separating force not enough, so it is not particularly suited for the circuit board of large-size,
Simultaneously when circuit-board laying-out is fuller, when front panel device is more, drawing-aid device is fitted with PCB surface and takes volume, be have impact on and is patched
The density of part.
Utility model content
The package density of pcb board is not influenceed in order to obtain larger contact engaging and separating force simultaneously, and the utility model, which provides one kind, to be helped and pull out
Device.The technical solution of the utility model is：By drawing-aid device spring, drawing-aid device steel ball, drawing-aid device rotational pin, drawing-aid device handle is helped
Pull out device fixed seat composition；Described drawing-aid device handle is fixed in drawing-aid device fixed seat by drawing-aid device rotational pin, and can
To be rotated around the drawing-aid device rotational pin in drawing-aid device fixed seat；Described spring steel ball is additionally provided with drawing-aid device handle,
When drawing-aid device handle rotate in place, steel ball is slided into the groove of drawing-aid device fixed seat, so as to lock drawing-aid device handle and prevent it
Vibrate and loosen with cabinet, described drawing-aid device fixed seat be arranged on when in use on one piece of installing plate orthogonal with pcb board and
Do not contacted with pcb board, so being not take up the plug-in unit area of pcb board.
The utility model is using the beneficial effect of above technical scheme：Using single fixing seat mounting structure so that
Drawing-aid device can be without on pcb board, it is to avoid take the plug-in unit area of pcb board；While the spring steel of drawing-aid device handle
Pearl effectively can prevent handle from loosening；And the length of described handle is larger, larger torque can be provided so that pcb board
Plug is more laborsaving.
Brief description of the drawings
Fig. 1 is the application structure schematic diagram of existing drawing-aid device；
Fig. 2,3,4 are the overall structural representations of the utility model；
Fig. 5 is application structure schematic diagram of the present utility model.
Embodiment
As shown in Fig. 2 the utility model is by drawing-aid device spring 1, drawing-aid device steel ball 2, drawing-aid device rotational pin 3, drawing-aid device hand
Handle 4, drawing-aid device fixed seat 5 is constituted；Described drawing-aid device handle 4 is fixed on drawing-aid device by drawing-aid device rotational pin 3 and fixed
On seat 5, it is possible to rotated around the drawing-aid device rotational pin 3 in drawing-aid device fixed seat 5；As shown in Figure 3,4, drawing-aid device handle 4
Described spring steel ball 1,2 is inside additionally provided with, when drawing-aid device handle rotate in place, steel ball 2 slides into the groove 6 of drawing-aid device fixed seat
It is interior, so as to lock drawing-aid device handle 4 and prevent that it from vibrating and loosening with cabinet, as shown in figure 5, described drawing-aid device fixed seat 5
It is arranged on when in use on one piece of installing plate 7 orthogonal with pcb board 8 without being contacted with pcb board 8, so being not take up pcb board 8
Plug-in unit area.
Above-mentioned embodiment is exemplary, is to make in order to more preferable skilled artisans appreciate that originally
Patent, it is impossible to be not understood as including this patent the limitation of scope；As long as technical scheme is made according to disclosed in this patent
The substantially identical or equivalent any change or modification of technology contents, each fall within the scope that this patent includes.
Claims (1)
