Description

A kind of door stop

Technical field

The utility model relates to door stop, in particular for the door stop of rack.

Background technology

Rack of the prior art, switchboard etc. are widely used in the electric equipment system, and the appliance components such as switch, protection and detection control of cupboard all are installed in the sealing shell usually., need door be opened by needs when overhauling, safeguard perhaps other operations, but easy moving of rack more, and opening angle is difficult for fixing, and brings greater inconvenience to operations such as maintenances.

In order well to limit rack door-plate opening angle, door-plate is located accurately and reliably, each manufacturer of rack industry just designs, has produced various door stops.

At present, the door stop of rack industry mainly adopts friction to pull formula and coupling type:

One, friction pulls the formula door stop, comprises C shape groove seat and C shape connecting rod, makes its fricting movement under the location of C shape groove seat realize ending door through pulling C shape connecting rod, has it to have following problem:

(1) owing to adopt friction to pull, use the door stop wearing and tearing big for a long time, the operation effort;

(2) complex structure, processing and fabricating are cumbersome;

(3) restriction of the contour structures of door stop only is suitable for the lifting type mode of opening the door, and is not suitable for left and right opening door mode (mode of the opening the door great majority of rack all are left and right opening door), has bigger limitation.

Two, the coupling type door stop mainly contains hook and rhampotheca two parts composition, and hook is installed on the cabinet, and rhampotheca is installed on the cabinet door, and there is following problem in it:

(1) need both hands to operate simultaneously, catch hook on the other hand, another hand rotates door-plate and will link up with to go in the rhampotheca to suitable position, and general cabinet door quality is big, and operation is wasted time and energy.

The utility model content

The applicant uses shortcomings such as unreliable to door stop complex structure in the above-mentioned prior art, provides a kind of rational in infrastructure, makes and door stop easy for installation, thereby simple in structure, it is reliably convenient to use, and cost is low.

The technical scheme that the utility model adopted is following:

A kind of door stop comprises connector, and said connector becomes " right angle " structure, and the said connector first right-angle side top has a plurality of slotted holes at interval, and securing member is installed in the said slotted hole; Second right-angle side of said connector is provided with chute, the bar that is articulated and connected on the said chute, an end of said connecting rod and the said chute formation moving sets of extension at its length direction.

Its further technical scheme is:

Said connecting rod one end is provided with first circular hole, and said first circular hole is articulated in the chute through the riveting axle; The said connecting rod other end has second circular hole, and said second circular hole two ends up and down is connected with flange bolt through the pad axle respectively;

Said chute two ends are provided with big hole;

The column structure that said riveting axle successively dwindles from top to bottom.

The beneficial effect of the utility model is following:

Door stop is simple in structure, and is easily manufactured, is installed on when using on the rack, and the rotation of door can realize the angle that limiting door is opened freely easily, its adjustable angle, and after the door unlatching puts in place, can also be through the automatic position and lock of effect of gravity.The utility model can be widely used on various the device of left and right opening door mode, and cost is low.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.

As depicted in figs. 1 and 2, the described door stop of the utility model comprises connector, and connector becomes " right angle " structure, and connector first right-angle side 3 tops have slotted hole 2 at interval, mounting screw 1 in the slotted hole 2; Second right-angle side 6 of connector is provided with the chute 4 of extension at its length direction, the bar 8 that is articulated and connected on the chute 4, and an end of connecting rod 8 and chute 4 form moving sets; Connecting rod 8 one ends are provided with first circular hole, 7, the first circular holes 7 and are articulated in the chute 4 through riveting axle 5; Connecting rod 8 other ends have second circular hole, 10, the second circular holes and are connected with bolt 9 through pad axle 11 respectively at two ends about in the of 10; Chute 4 two ends are provided with big hole 15, and big hole 15 is used for the limit stop position of positioning link bar 8; The column structure that riveting axle 5 successively dwindles from top to bottom; When dropping in the chute 4, the smallest cylinder place of riveting axle 5 also can move around; The intermediate cylindrical effect is; Open when door and riveting axle 5 to be stuck in big hole 15 places at chute 4 two ends after putting in place, stop it to get into chute 4 (stop location), maximum cylinder then is that prevention riveting axle 5 drops for 15 li from the big hole of chute 4 after the door unlatching puts in place.

See Fig. 3 and Fig. 4; The utility model is applied on the rack 12, and door stop is installed on rack 12 bottoms, and first right-angle side 3 of connector is installed on the inboard of door-plate 13; Screw 1 is passed slotted hole 2 to be fixed on the square tube of door-plate 13 bottoms; Because the design of slotted hole 2 can realize connector left and right adjusting on door-plate easily on first right-angle side 3, reasonably controls the opening angle of door-plate 13; Big column end face on the pad axle 11 is attached on the section bar 14 of rack 12, and second circular hole 10 of connecting rod 8 one ends is nested on the small column of pad axle 11, connecting rod 8 is lock onto on the section bar 14 through bolt 9 at its top then; And with its location, axle center; The other end of connecting rod 8 is articulated in through riveting axle 5 in the chute 4 of connector, and the open and close along with door under the guiding of the chute 4 of connector make connecting rod 8 slide along chute 4, when in the big hole 15 that slides into chute 4 one ends; Because action of gravity; Riveting axle 5 is automatic whereabouts in big hole 15, thus the automatic whereabouts of realizing door stop, and door unlatching this moment puts in place and is locked; During release, with carrying on the riveting axle 5, the hand push door-plate rotates to the direction of cutting out with pin, this moment of release.

More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
