The lower section of limited block 431；The second limited block 432 is partially passed through below the spacing head of second rod piece 42, along length side
To reciprocating movement；Second spring part 46 is connected between 421 bottom of spacing head and the second limited block 432；
When protective shell 1 is by top-down shock, impact force is conducted to the second rod piece 42,421 stress of spacing head
It moves down；The conical surface of spacing head 421 is produced relative sliding with the first limited block 431 at this time, and 45 stress of the first spring part compresses, resistance
It is gradually increasing and absorbs impact force, subsequent spacing head 421 replys initial position；When impact force is excessive, spacing head 421 is further
Decline, conical surface lower end squeeze second spring part 46, then the first spring part 45 and second spring part 46 together absorb impact force,
Spacing head finally replys initial position；Second limited block 432 can be effectively prevented 421 dropping distance of spacing head it is excessive and with first
Limited block 431 is detached from cooperation；As shown in the figure, 432 upper end of the second limited block is with the identical chamfering of gradient and spacing head 421
The conical surface it is corresponding, the contact area that both can be effectively increased avoids the conical surface from hitting and scratches or deformation, can effective extending structure
Working life；
When protective shell 1 is by shock from bottom to top, impact force is conducted to the second rod piece 42,421 stress of spacing head
It moves up and converts potential energy for impact force, the conical surface of spacing head 421 is produced relative sliding with the first limited block 431 at this time；Then, it limits
Potential head 421 moves down under the gravity of lower section device to be returned near original position, and with second spring part 46 in vertical side
It moves back and forth by a small margin upwards；The amplitude of reciprocating movement can between the first limited block 431 and spacing head 421 frictional force effect
Become smaller rapidly down, final spacing head 421 is static, completes bradyseism process.
As shown in Fig. 7, second rod piece 42 circumferentially spaced-apart is provided with sliding block close to the one end side of spacing head 421
47；Sliding slot 49 is provided on the inside of second limited block 432；The sliding block 47 is embedded in sliding slot 49, the second rod piece of limitation 42 with
It is relatively rotated between second limited block 432；When the corresponding projection screen of projection arrangement changes, the first rod piece can be passed through
41 and the second rotation between rod piece 42 carry out the deflection of projection angle and adjust, degree of regulation depends between adjacent sliders 47
Corner dimension；Two sliding blocks 47 in figure are only to illustrate, and sliding block 47 can be greater than two, between adjacent sliders 47 in practical structures
Angle determine projector's horizontal direction angle adjust precision.
As shown in Fig. 8, rotation aligning device 5 is provided between the protective shell 1 and the second rod piece 42, it can be by turning
It is dynamic to absorb the impact force suffered in the horizontal direction of protective shell 1；The rotation aligning device 5 includes attaching means 6 and rotating member 7；
The attaching means 6 is fixedly mounted on the inside top of protective shell 1；7 lower end of attaching means is provided with circular trough 71；The rotation
Part 7 is embedded in circular trough 71, is completed the constraint on vertical direction by forms such as baffles below rotating member 7 and is fixed；Described
Two rod pieces, 42 lower end passes through the top of protective shell 1, is fixedly connected with rotating member 7, thus after protective shell 1 receives device, realize by
Aligning device 5 is rotated to absorb horizontal direction power, while will be in vertical direction on conduction to suspension arrangement 4.
Third limited block 72 is provided on 71 side wall of circular trough；Third spring part 73 is provided on the rotating member 7
With the 4th spring part 74；The third spring part 73 is identical with 74 structure of the 4th spring part；The third spring part 73 and the 4th
Spring part 74 is symmetricly set on 72 two sides of third limited block, and is located on same rotation path with third limited block 72；Described

6. the working method that a kind of protecting against shock quickly returns orthographic projection instrument device：
After being hit, projection arrangement includes the following steps in the bradyseism of vertical direction,
Step 1, impact force conduction are conducted by protective shell (1) to the second rod piece (42), and spacing head (421) is under impact force action
It moves；
Spacing head (421) kinetic energy absorption is then driven spacing head (421) to move reciprocatingly by step 2, second spring part (46)；
Step 3, spacing head (421) conduct part kinetic energy on the first spring part (45) in moving process, the first limited block
(431) with the lifting of spacing head (421) stretching motion in the horizontal direction；
The reciprocating movement amplitude of step 4, spacing head (421) reduces, and in its frictional force between the first limited block (431)
Lower immediate stability is acted on to stationary state；
Projection arrangement bradyseism in the horizontal direction includes the following steps,
Step 1, impact force suffered by protective shell (1) are conducted by third limited block (72) to third spring part (73) and the 4th spring
On part (74), reciprocating rotation occurs for attaching means (6) and rotating member (7)；
Step 2, the rotation amplitude between attaching means (6) and rotating member (7) are gradually reduced under the action of frictional force；
Attraction returns rotating member (7) and attaching means (6) quickly between step 3 and the first magnetic patch (75) and the second magnetic patch (76)
Initial corresponding position and stabilization are arrived again；
It is when view field position needs to adjust, the first limited block (431) is mobile along the length direction of the first rod piece (41), with
The mounting hole of cavity (43) side different height, which cooperates, to be fixed, and realizes the height change of view field；By the second limited block (432)
After removing, separates the second rod piece (42) with the first rod piece (41) and rotate the angle adjusted to needs, then make sliding block again
(47) cooperate with sliding slot (49), then the second limited block (432) are installed in meeting cavity (43), complete view field's horizontal direction
Variation.
