Space realize function, cause next drawer to will be unable to normally extract out, this structure is brought very to client in actual use
More puzzlements.
Therefore, the first specific embodiment also has the characteristics that: when intermediate drawer extracts half out, will not influence a He
The normal extraction of next drawer or functional unit；Structure is simple ,+two axle sleeves of an only sheet metal component, at low cost；It is dropproof
Device realizes reset under gravity, and without any energy-storage units, reliability is high, and cost is very low.Its unlocking manner are as follows: only
Need to be lifted up the resetting structure 3 of the body of rod 1 with hand can be realized unlock, and mode of operation is simple, reliably.The utility model is implemented
The fall-proofing device that example provides will not avoid influencing the use of other drawers.
In second of specific embodiment:
In use, fall-proofing device provided by the utility model is arranged on the side wall of switch cabinet drawer 7, hook 2 is downward
Setting, resetting structure 3 are arranged upward, and the baffle 8 being used cooperatively with hook 2 is provided on the cabinet body of switchgear, then drawer is inserted
After entering, the body of rod 1 realizes reset under the effect of gravity, and is maintained at original state, i.e. the hook 2 in 1 front of the body of rod sinks,
Resetting structure 3 is lifted up；When drawer extraction, hook 2 blocks on the baffle 8 on the functional unit bottom plate, makes drawer can not be after
Continuous extraction, thus realize dropproof function, so that avoiding overexerting at the beginning causes drawer to be fallen after quick extracted out, this
When, need to press the unlock of resetting structure 3, hook 2 upwarps, and drawer, which can unlock, to be continued to extract out, prevents drawer from extracting out quickly
Fallen accident in journey.
In second of specific embodiment, mainly for drawer in extraction process, in fact it could happen that accident and
The preventative design taken.Stopped suddenly during fast moving using drawer, so that drawer center of gravity moves to the outer Shi Nengyi of cabinet
It so rests in drawout cubicle, operative employee needs to take a movement that could unlock, to extract out and remove drawer.Due to there is this
Unexpected fallen accident would not occur in process.
It is specific:
1, fall-proofing device provided by the utility model is located on the movable part of drawer, and gear can be touched in extraction process
Plate 8 and the removal for stopping entire drawer in turn；
2, the body of rod 1 is under self gravitation effect, front end downsagging, so that the process in drawer extraction is stuck on baffle 8,
The gravity center eccentric of part is utilized, realizes position locking；
3, the fixation of the body of rod 1 is fixed using the shouldered tap bolt of standard, and factory is easy to buy；
4, the body of rod 1 is panel beating forming, facilitates factory process；
5, do not increase components additionally, baffle can use the fixation bottom plate of original drawer, prevent drawer from falling.
In addition, for the first specific embodiment:
It is specific:
1, the body of rod 1 is rotated clockwise to initial position around the first pin shaft 4 under the effect of gravity；Second pin shaft 5
Limit the angle of rotation；Hook 2 on the body of rod 1 is in tilting state in the initial state；
2, the body of rod 1 of this fall-proofing device is to realize spinning reduction, nothing around the first pin shaft 4 under the effect of gravity
Need any external force；
3, the unlock of this fall-proofing device only needs the resetting structure by the body of rod 1 to be lifted up, and dropproof dress can be realized
The unlock set, unlocking method is simple, reliably.
In order to advanced optimize above scheme, inclined side is provided on hook 2 and the angle α of the inclined side and the body of rod 1 is
Acute angle, as shown in figure 3, its inclined direction is to be increased by the direction far from the body of rod 1 towards the direction close to the body of rod 1, Convenient switch
The insertion of cabinet drawer 7, the bottom plate cooperation with a upper functional unit, which is realized, is inserted directly into drawer, is not necessarily to any operation.
Specifically, strip hole 6 is acute angle along the rotational angle of the second pin shaft 5, facilitate between strip hole 6 and the second pin shaft 5
Opposite sliding, reliability is higher.
In order to advanced optimize above scheme, the end of the first pin shaft 4 is provided with the first axle sleeve, and first axle set has simultaneously
Realize the turning function of the first pin shaft 4 and the function that the limitation body of rod 1 falls off, the end of the second pin shaft 5 is provided with for blocking bar
Second axle sleeve of body 1, the second axle sleeve realize three functions；1. the turning function of pin shaft；2. the function that the limitation body of rod 1 falls off；3.
Cooperate the function of realizing rotation with strip hole 6.
The utility model embodiment also provides a kind of switch cabinet drawer 7 with dropproof function, including drawer body and
Fall-proofing device, fall-proofing device are the fall-proofing device as described in above-mentioned any one embodiment, and fall-proofing device setting exists
On the side wall of drawer body, it is not take up the installation space of drawer, and reliability is high.
Specifically, fall-proofing device is two and is separately positioned on the two sides of drawer body, alternatively, fall-proofing device is one
It is a, the left side or right side of drawer body are set.The installation site of fall-proofing device includes: 1, is mounted on the left side of drawer；
2, it is mounted on the right side of drawer；3, the side of the left and right of drawer two is all installed.The body of rod 1 is sheet metal component, and cost is very low.First pin shaft
4 and second pin shaft 5 be guide pin and have the function of axle sleeve, prevent the body of rod from falling off.Drawer body is assemblied in using self threading pin
Side wall on.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
