Specific embodiment
Below with reference to examples and drawings, detailed description further made to the utility model, but the utility model
Embodiment is without being limited thereto.
As shown in Figure 1 and Figure 2, the utility model provides a kind of shatter-resistant digital pen, including pen container 1, telescopic device 2 and pressing
Device 3.As shown in figure 4,1 front end of pen container is equipped with notch 11,1 surface of pen container is equipped with a through-hole 12, the through-hole 12
Near 1 middle-end of pen container, the telescopic device 2 is installed in pen container 1, as shown in figure 3, the telescopic device 2 includes successively
Protection sleeve 21, adjustable spring 22 and the limited block 23 of connection, the limited block 23 are fixed on 1 rear end position of pen container, and
It is placed centrally along 1 radial direction of pen container, 22 one end of adjustable spring is fixed among limited block 23, the other end and protection sleeve 21
Center connection, three center is located along the same line and is overlapped with 1 central axes of pen container.21 surface of protection sleeve be equipped with one with
The skewed slot 211 that the press device 3 cooperates, the skewed slot 211 is close to one end that protection sleeve 21 is connect with adjustable spring 22, institute
It states 3 lower end of press device to abut with the skewed slot 211, the two is 45 ° of contact of incline plane, guarantees telescopic device 2 and press device 3
Cooperation operation is smooth, and 3 upper end of press device is installed in the through-hole 12.As shown in Figure 1, in the non-use state, i.e., hand with
Pen container 1 is contactless, and press device 3 does not stress, and lower end will be abutted with 211 upper end of skewed slot on protection sleeve 21, adjustable spring
22 are now in former long status, and protection 21 front end of sleeve will be stretched out from the notch 11 of 1 front end of pen container and half wraps up pen core, to rise
To the effect of protection pen core；As shown in Fig. 2, in a state of use, hand contacts the press device 3 on pen container 1 and applies pressure to it
Power, press device 3 move vertically downwards, and lower end inclined-plane and skewed slot 211 generate extruding, cause to protect sleeve 21 along water
Square to movement, to make cartridge exposing, meet requirement, and at the same time, adjustable spring 22 is in compressive state, when making
It is fallen accidentally with digital pen in the process or when using finishing, protection sleeve 21 can stretch out pen under the elastic force effect of adjustable spring 22
Cylinder 1 protects the function of pen core to realize.When pen core is in non-working condition or guard mode, press device 3 protrudes pen container 1
The height on surface is corresponding with 211 depth of skewed slot consistent, may insure in this way will not because of in excessively pressing press device 3,
The protection sleeve 21 of lower end in contact can be deformed and cause to run it is unsmooth, in addition when digital pen when in use, pressed due to described
3 upper end shape of pressure device is corresponding with 1 surface shape of pen container, and the upper end of the press device 3 and pen container 1 will form one completely
It is whole.
The protection sleeve 21 is to be driven by adjustable spring 22, and the decrement of adjustable spring 22 is to protect sleeve 21
The length of pen container 1 is stretched out, and since 23 position of limited block is fixed and invariable, so when in use, needing hand-held continue firmly
The elastic force of adjustable spring 22 is offset with this, it in this way can be for a long time in use, being more troublesome.It proposes to solve this problem following
Technical solution, as shown in figure 4,1 surface of the pen container is additionally provided with a waist-shaped hole 13, the waist-shaped hole 13 is located at the through-hole 12
Same orientation, the limited block 23 are installed in the waist-shaped hole 13, and 13 side wall of waist-shaped hole is equipped with limit card slot
131.Adjustable spring 22 is set to restore former length by mobile limited block 23, thus when long-time uses digital pen, without exerting a force,
Protection sleeve 21 will not stretch out pen container 1 and influence normal use, and the setting of limit card slot 131 is telescopic device 2 in order to prevent
Shaken back and forth in pen container 1, influence using.
As shown in figure 3, the protection sleeve 21 is along the circumferential direction distributed with 3 close to 22 end surface of adjustable spring
Raised line 212, raised line 212 is non-uniform to be distributed on the periphery for protecting sleeve 21, and 1 inner wall of pen container is equipped with matched
Groove 14, be between any one groove 14 and raised line 212 it is unique corresponding, the length of groove 14 is not less than adjustable spring 22
Decrement, groove 14 be it is rectangular, can prevent raised line 212 from rotating, it is ensured that protection sleeve 21 is moved along horizontal linear, while raised line
212 also have positioning action with the cooperation of groove 14, can realize the installation to whole device faster.
As shown in figure 5, the press device 3 includes strut 31, pedestal 32, fixed frame 33 and spring 34, the fixed frame
33 are installed in through-hole 12, and fixed frame 33 is equipped with one for wearing the mounting hole 331 of strut 31, and the strut 31, which passes through, to be fixed
Mounting hole 331 on frame 33 is fixedly connected with the pedestal 32, and the spring 34 is socketed on strut 31, and 34 both ends of spring point
Be not fixedly connected with fixed frame 33 and pedestal 32,31 upper end of strut includes a head for pressing, the pedestal 32 with
211 abutment end gradient of skewed slot is consistent with 211 gradient of skewed slot.When pressing 31 head of strut, strut 31 drives pedestal 32 to move downward,
Spring 34 will be stretched, and remove the active force of pressing, and spring 34 restores original length, and pedestal 32 is driven to move up, pedestal 32 to
The vertical range of lower movement is consistent with 211 depth of skewed slot, i.e., when spring 34 in a state of nature when, pedestal 32 and skewed slot
211 upper ends abut, and when the stretching of spring 34 reaches maximum value, pedestal 32 is abutted with 211 lower end of skewed slot.To ensure device operation
Smooth, easy to use, the coefficient of elasticity of spring 34 need to be less than the coefficient of elasticity of adjustable spring 22, and pedestal 32 is using lighter weight
Material production, 31 head shape of strut is corresponding with 1 surface shape of pen container and head size and 12 size of through-hole are corresponding.
Specific working mode: when in use, hand holds the press device 3 on pen container 1, and press device 3 moves downward drive
For telescopic device 2 along 1 central axes direction of pen container to end motion after pen container 1, the protection for making pen core be detached from protection sleeve 21 is completely exposed,
When in use process digital pen fall accidentally or use after, protection sleeve 21 adjustable spring 22 elastic force effect under, edge
End motion stretches out pen container 1 from notch 11 to 1 central axes of pen container forward and half wraps up pen core, to play the role of protecting pen core.
