Abstract
The present invention relates to a kind of anti-collision device for trolley, including anticollision frame, the anticollision frame is provided with chute, and level is slidably fitted with impact block on the chute.Paired sideskid is placed with anticollision frame in the horizontal direction, each madial wall of the sideskid with anticollision frame is weldingly connected, the brake block of rectangular triangle is slidably fitted with each sideskid along the longitudinal direction, the No.1 spring that the two is connected each is equipped between brake block and the madial wall of anticollision frame, the right side of the brake block of each two correspondences, which is supported to close, one piece of pressing block in isosceles trapezoid, and each pressing block supports to close with corresponding brake block inclined-plane to be coordinated.Delicate structure of the present invention, not only by the setting of three kinds of springs and the cooperation of pressing block and brake block, can by because of shock and caused by the effect that is progressively slowed down of enormous impact force, and then good protection is given when children play, there is higher security.
Description
Technical field
The present invention relates to one kind to entertain protection kind equipment, specifically a kind of anti-collision device for trolley.
Background technology
As a rule, child during growth and development, it is necessary to buy corresponding toy or simulated instrument to help
Child goes to recognize this every affairs in the world.The car a kind of vehicles the most frequently used as people, in order to allow child can
Having a taste of the function of car, usual parent can allow child to go to amusement park to go seating dolly to play, during playing, each dolly
Between can be collided unavoidably, and child is weak, and huge impact caused by this collision often make it that child is injured.
The content of the invention
Now in order to ensure safety of the child when dolly is played, the present invention proposes a kind of anti-collision device for trolley.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of anti-collision device for trolley, including anticollision frame, the anticollision frame are provided with chute, and level is sliding on the chute
It is dynamic that impact block is installed.
Paired sideskid, madial wall of each sideskid with anticollision frame are placed with anticollision frame in the horizontal direction
Be weldingly connected, be slidably fitted with the brake block of rectangular triangle on each sideskid along the longitudinal direction, each brake block with
It is equipped with the two connected No.1 spring, the right side of the brake block of each two correspondences between the madial wall of anticollision frame
Support to close and have one piece of pressing block in isosceles trapezoid, each pressing block supports to close with corresponding brake block inclined-plane to be coordinated；In level
On square, it is equipped with the two No. two connected spring between each two brake block；The compacting of the rightmost side in the pressing block
No. three springs that the two is connected are provided between block and impact block.
The sideskid has three pairs.
The beneficial effects of the invention are as follows：
Delicate structure of the present invention, can will not only by the setting of three kinds of springs and the cooperation of pressing block and brake block
The effect that enormous impact force caused by because of shock is progressively slowed down, and then good protection is given when children play, have
Higher security.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the top view of the present invention；
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
In order that those skilled in the art is better understood from technical scheme, below in conjunction with embodiment
Accompanying drawing, the present invention is become apparent from, it is more complete illustrate, certainly described embodiment be the present invention a part rather than
All, based on the present embodiment, the others that those skilled in the art are obtained without having to pay creative labor are real
Example is applied, within the scope of the present invention.
As shown in Figure 1 to Figure 2, a kind of anti-collision device for trolley, including anticollision frame 1, the anticollision frame 1 are provided with chute
Level is slidably fitted with impact block 2 on 1a, the chute 1a.
Paired sideskid 6 is placed with anticollision frame 1 in the horizontal direction, each sideskid 6 is interior with anticollision frame 1
Sidewall weld is connected, and is slidably fitted with the brake block 5 of rectangular triangle on each sideskid 6 along the longitudinal direction, each system
The No.1 spring 7 that the two is connected, the system of each two correspondences are equipped between motion block 5 and the madial wall of anticollision frame 1
The right side of motion block 5, which is supported to close, one piece of pressing block 4 in isosceles trapezoid, and each pressing block 4 supports with the corresponding inclined-plane of brake block 5
Close and coordinate；On level is square, it is equipped with the two No. two connected spring 3 between each two brake block 5；The pressing block
No. three springs 8 that the two is connected are provided with 4 between the pressing block 4 of the rightmost side and impact block 2.
The sideskid 6 has three pairs.
The left end of a pair of sideskids 6 of the leftmost side and the headstock of dolly before use, need to only be fixedly connected with, use by the present invention
When, when two dolly head-on crashes, impact block 2 can be hit first so that the Slideslip, and compress three to the left of impact block 2
Number spring 8, and under the slip effect of No. three springs 8, one piece of pressing block 4 of the rightmost side is moved backward, and this can not only be pressed
No. two springs 3 of contracting simultaneously transmit impulsive force to next pressing block 4, but also can be by sideskid 6 corresponding to two pieces respectively forwardly
Side, rear side carry out corresponding promotion, then compress No.1 spring 7.In No. three springs 8 and substantial amounts of No.1 7, No. two springs of spring
Under 3 elastic buffer effect, when impulsive force is delivered on a pair of sideskids 6 of the leftmost side, impulsive force has become very small,
And then safety is ensured.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement is both fallen within claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
