Abstract

The utility model relates to a stepless door braking device which comprises a base, a hollow lifting rod, a braking lever of which the upper end extends into the lifting rod and forms loose connection with the lifting rod, wherein, the top end of the braking rod has a rod braking spring; two base springs are arranged in the base; the lifting rod is provided with bevel teeth which are arranged up and down and engaged with a wedge block at the inner side of a bottom cover of the base; the wedge block is abutted with the braking pole through a wedge block spring. The lifting rod only needs to be stamped downwards to cause the braking rod to tightly bunt the ground; through the engaged lockage of the wedge block and a toothed rack, a door leaf can not be reset, namely braked tightly. When the door is closed, the braking rod is pulled with the door leaf to automatically release the brake, and men do not need to operate again.

Description

The stepless brake door is stopped

The utility model relates to a kind of device that the building wing is held open, and particularly makes wing keep the stepless brake door of any opening angle to stop.

For keeping door leaf to open, prevent to be moved by wind, adopt usually to patch member or adhesive member, this member is loaded on door leaf and interior wall inferior horn, door leaf is linked to each other with metope grafting or adhesive, reach the fixedly effect of door leaf, but this member can only keep the door leaf full-gear.Make door leaf keep a certain aperture, adopt at present preferably method be with inclined-plane voussoir jam-pack in the student, need at closing time voussoir is taken out, cumbersome.

The purpose of this utility model provides a kind of stepless brake door and stops, make the door leaf aperture stepless stop fixed, un-brake automatically at closing time.

The utility model comprises a base that is fixed on the door leaf inferior horn, the hollow elevating lever that can in base, move up and down, a upper end is stretched in the elevating lever and with elevating lever and is become flexible the bar of stopping that connects, the masthead end of stopping is equipped with the bar spring of stopping, two base springs are housed in the base, elevating lever is provided with the inclined-plane tooth that is arranged above and below, and it is meshed with the voussoir of base bottom inboard, and voussoir also offsets by the voussoir spring and the bar of stopping.The above-mentioned bar of stopping is connected with the slotted hole of elevating lever is loosening by transverse axis, and the anti-slip rubber cover is equipped with in the bar lower end of stopping.

This locator only need be trampled elevating lever downwards when using, and its drive bar of stopping is moved downward, and is tight against ground until the bar lower end of stopping, and elevating lever can't upwards reset with some inclined-planes tooth and voussoir engages fixed, this moment door leaf promptly quilt stopped tightly in a certain aperture position.At closing time, along with door leaf is pulled, voussoir promptly withdraws from between engaging tooth, and elevating lever upwards resets rapidly under the base spring action, and the bar of stopping is automatic built on stilts, and the door leaf un-brake need not outer add operation, and is easy to use.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 is the front view that the stepless brake door is stopped.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 2.

Fig. 4 is that the C of Fig. 3 is to view.

Fig. 5 is the D-D sectional drawing of Fig. 3.

As shown in Figure 1, the elevating lever 1 of hollow can oscilaltion campaign in base 3, and base 3 is installed on the inferior horn of door leaf by connecting hole 31 usefulness screws.The bar 4 lower ends covers rubber sleeve 5 of stopping, the upper end is with slotted hole 11 loosening link of transverse axis 6 with elevating lever 1, stopping is provided with the bar spring 2 of stopping in the top of bar 4 and the space between the elevating lever 1, two base springs 10 about being equipped with in the base, spring upper end and elevating lever 1 offset (seeing Fig. 1,3).The back side of base 3 is provided with bottom 32 (see figure 2)s, the back side of elevating lever 1 has two inclined-plane tooth bars 12 (seeing Fig. 2, Fig. 5), be provided with voussoir 7 (see figure 2)s between bottom 32 and the elevating lever 1, be tight against the bar 4 of stopping (seeing Fig. 2,3) forward and make its two inclined-planes 71 and the inclined-plane tooth of tooth bar 12 mesh (see figure 5) by voussoir spring 8.The top plan view shape of voussoir 7 is seen Fig. 4, and front end face 72 is tight against the bar 4 of stopping forward because of the effect of spring 8 among the figure, about two inclined-planes 71 and 12 engagements of inclined-plane tooth bar.

During use, can trample elevating lever 1 downwards, make it to lower compression base spring 4, the continuous tooth of the pitch face of this hour rack 12 slides downwards on voussoir 7 inclined-planes 71, when the bar 4 of stopping arrives at ground, therefore ground continue to trample elevating lever 1 in the face of the bar of stopping produces reaction force, and the bar spring 2 of stopping is compressed, the bar 4 of stopping promptly continues to be tight against ground downwards in the scope of slotted hole 11, this moment, stop was trampled, and voussoir 7 meshes with the tooth bar tooth, and it can't upwards be resetted the elevating lever locking, thereby make the bar of stopping keep being tight against the state on ground, utilize the frictional force on lower end rubber sleeve and ground, door leaf is stopped due to this aperture position, can un-brake under the general wind situation.When needs are closed the door and are spurred door leaf 9, owing to the bar lower end of stopping is subjected to the frictional ground force action that relatively lags behind, cause voussoir spring 8 that it is lost the power of being tight against, the voussoir tooth withdraws from tooth bar, and elevating lever 1 promptly is subjected to the 10 elastic force effects of base spring and upwards resets rapidly.The bar 4 automatic un-brakes of stopping need not add manually-operated.

Claims

1, the stepless brake door is stopped, it is characterized in that comprising a base, one can elevating movement in base hollow elevating lever and a upper end stretch in the elevating lever and with the loosening bar of stopping that is connected of elevating lever, the masthead end of the stopping bar spring of stopping, two base springs are arranged in the base, elevating lever is provided with the inclined-plane tooth that is arranged above and below, and it is meshed with the voussoir of base bottom inboard, and voussoir offsets by the voussoir spring and the bar of stopping.

2, stepless stop door according to claim 1 is stopped, and the bar that it is characterized in that stopping is connected with the slotted hole of elevating lever is loosening by transverse axis.
