Abstract

The utility model discloses a kind of drawer chassis of omnipotent breaker, two sides extend to form flange to the left and right respectively for the left plate of the drawer chassis and right side plate bottom, the skid that the flange corresponds to wooden case baseplate underside opens up fixation hole, and the drawer chassis is fixed on wooden case bottom plate by being inserted into self-tapping screw in fixation hole.The labor intensity of worker when the drawer chassis reduces packaging eliminates foreign matter and enters inside drawer chassis the hidden danger for causing drawing mechanism stuck, and reduces the requirement to wooden case base plate strength.

Description

A kind of drawer chassis of omnipotent breaker

Technical field

The utility model relates to a kind of drawer chassis of omnipotent breaker.

Background technique

Existing drawer type omnipotent breaker is being transported or is being carried since its weight is generally tens kilograms or more Before, wooden-box package can be all used, the mounting hole that the bottom plate inside drawer chassis is equipped with just can sharp its mounting hole progress and wood The fixation of bottom plate.As shown in Figure 1, breaker body need to be taken out from drawer chassis 2, then used before transport or carrying The screw assembly 4 that screw, nut, elastic washer, flat shape washer form passes through the mounting hole 21 on drawer chassis bottom plate for drawer chassis 2 It is fixed on wooden case bottom plate 3, then breaker body is packed into drawer chassis 2.

As it can be seen that the drawer chassis 2 of existing omnipotent breaker has the following problems:

1) packaging is carried out in factory or user terminal is unpacked when filling, due to small in 2 inner space of drawer chassis, can not use Electric screw driver, locking and when unclamping screw generally can only manual work, need artificial one by one at least two fixed screws Carry out operation of uncaging, large labor intensity, low efficiency.

2) when user terminal removes wooden case bottom plate fixed screw, there are individual bolts, nut, elastic washer, flat shape washer etc. It does not clean out, and runs the moving component position into the drawing mechanism of drawer chassis 2, cause drawing mechanism stuck, lead to breaker Ontology can not be connect with drawer chassis 2 in place or breaker body 1 can not be released from drawer chassis 2, and when occurring stuck, often The drawing mechanism of drawer chassis 2 is caused to deform, scene can not repair, and bring adverse effect to customer complaint processing.

3) existing product, due to the position of the mounting hole 21 on the bottom plate inside drawer chassis 2, the thickness of wooden case bottom plate 3 Not enough, it needs the position below mounting hole 21 to increase additional batten 5 to increase the thickness (intensity) of bottom plate, spiral shell can be cooperated The installation of silk component 4, the original skid 31 of wooden case bottom plate 3 are only used as support.

In view of this, the present inventor proposes a kind of drawer chassis of omnipotent breaker convenient for assembly, thus this case generates.

Utility model content

The purpose of this utility model is to provide a kind of drawer chassis of omnipotent breaker, strong with the labour for reducing worker Degree eliminates foreign matter and enters inside drawer chassis the hidden danger for causing drawing mechanism stuck.

To achieve the goals above, the technical solution of the utility model is as follows:

A kind of drawer chassis of omnipotent breaker, two sides are prolonged to the left and right respectively for the left plate of the drawer chassis and right side plate bottom It stretches to form flange, the skid which corresponds to wooden case baseplate underside opens up fixation hole, by being inserted into self tapping spiral shell in fixation hole The drawer chassis is fixed on wooden case bottom plate by silk.

Further, the left plate and right side plate bottom are respectively formed former and later two flanges.

Further, the flange development length is without departing from side plate outer most edge.

After adopting the above scheme, the utility model has the beneficial effect that being inserted into self-tapping screw by the fixation hole in flange incites somebody to action Drawer chassis is fixed on wooden case bottom plate, breaker body is then packed into drawer chassis, since flange fixation hole is formed in pumping On the outside of drawer seat, operating space is big, and the self-tapping screw of can uncage by electric tool drawer chassis and wooden case bottom plate reduces worker's Labor intensity, it is convenient and efficient.Due to the self-tapping screw cooperated using nut, elastic washer, flat shape washer is not required to, additionally it is possible to eliminate Foreign matter enters inside drawer chassis the hidden danger for causing drawing mechanism stuck.

Drawer chassis is fixed on wooden case bottom plate and locks on people to the thicker skid of thickness by self-tapping screw, the weight of package It directly acts on the skid of support, weight distribution is more reasonable, reduces to base plate strength requirement, bottom plate with batten without being added Thickness saves packing case cost.

The utility model is further described in detail below in conjunction with the drawings and specific embodiments.

Detailed description of the invention

Fig. 1 is existing drawer seat installation structure perspective view；

Fig. 2 and 3 is the mounting structure schematic diagram of the utility model；

Fig. 4 is the structural schematic diagram that the utility model is packed into after breaker body.

Label declaration

Breaker body 1, drawer chassis 2, mounting hole 21, left plate 22, right side plate 23, flange 24, fixation hole 25, wooden case bottom Plate 3, skid 31, screw assembly 4, batten 5, self-tapping screw 6.

Specific embodiment

Such as Fig. 2-4 to a kind of shown, the drawer chassis for omnipotent breaker that the utility model discloses, the left side of 2, the drawer Two sides extend to form flange 24 to the left and right respectively for side plate 21 and 22 bottom of right side plate, which corresponds to wooden case baseplate underside Skid 31 opens up fixation hole 25, and drawer chassis 2 is fixed on wooden case bottom plate 3 by being inserted into self-tapping screw 6 in fixation hole 25.

To avoid increasing the size of product, 24 development length of flange of the present embodiment is without departing from left plate 22 and right side plate 23 Outer most edge.Moreover, former and later two flanges 24 are respectively formed in left plate 22 and 23 bottom of right side plate respectively, to guarantee the steady of fixation Solidity.

The utility model carries out packaging in factory or user terminal is unpacked when filling, and can uncage drawer chassis 2 by electric tool It with the self-tapping screw 6 of wooden case bottom plate 3, improves work efficiency, reduces manual working intensity, be packed into and release breaker body 1 When, because the inside of drawer chassis 2 does not have screw assembly, stuck situation is fallen because part may be not present.

The above are only specific embodiments of the present invention, not to the restriction of the protection scope of the utility model.It is all according to The equivalent variations that the mentality of designing of this case is done each falls within the protection scope of this case.
