Abstract

Disclosed is a stopping bolt which is a metal accessory making a door leaf can be positioned and stopped in any angles. The utility model comprises an outer shell, a pedal lever, a connecting rod, a slide block, a tappet, a pressure plate, a rubber pad and a spring. When the door leaf needs to be fixed in a certain position, the pedal lever is stepped by a foot to exert pressure on the connecting rod to drive the slide block to move downward to compress the spring to make the tappet obtain enough pressure. Stopping friction force towards the ground is increased by a plastic pad or the rubber pad supported by the pressure plate to fix the door. If the door leaf needs to recover to the free state, the pedal lever is lifted by the foot.

Description

Stopping bolt

The utility model relates to a kind of device of the door of building being located stop in desired location.

People are if want to open the door wide when utilizing the convection current natural ventilation, and owing to wind-force, wind direction, door leaf is often blown suddenly and cuts out by wind.Highrise building, this problem is serious more.Particularly spring, summer, Qiu Sanji and coastal area are because wind-force and the thing that door leaf glass is shatter happens occasionally.In addition in the shop or office, the place of the free door of all uses, when visitors flowrate was big, it was temporary fixed often to wish that door is opened wide the back.

The door bolt of extensively selling in the market must need be located the corresponding ground location boring of stop in use at door leaf, and latch inserts in the hole and can realize door leaf stop.But daily cleaning ground easily makes laying dust in the hole, latch is inserted not enter the hole and is lost stopping function.The latch of another kind of form on the market, though head added rubber cushion and need not hole on the ground, during use with foot-operated down because no force-increasing mechanism and keep structure to ground pressure, lift pin after latch not quite actual to the pressure on ground.When wind-force was big slightly, stopping effect was bad.Particularly when ground was very not smooth, above-mentioned shortcoming was more obvious.Moreover the Stopping bolt of this form on the market by the malalignment locking of spring, clamp and pin rod, with the passing of time also can further cause coupling mechanism force to descend the stopping effect variation during stop after the wearing and tearing.

The purpose of this utility model is that a kind of Stopping bolt will be provided, and the door leaf that can solve building is in the arbitrarily angled location stop problem of opening wide or cutting out.It can be applied to comprise is spreading plastic flooring, and carpet is on interior various ground.

Be described in detail hereinafter with reference to accompanying drawing.

Accompanying drawing 1 is the vertical section constructional drawing of embodiment.

Among the figure: 1, pedal lever 2, pin 3, shell 4, pin 5, connecting rod 6, pin 7, slide block 8, spring 9, tappet 10, platen 11, plastics or rubber pad 12, spring

Among the figure: one is connected with pin ［ 2 ］ on the shell ［ 3 ］ of drawing with the pedal lever ［ 1 ］ of steel sheet through drawing, and the distance at pin ［ 2 ］ to pedal lever ［ 1 ］ upper footboard center is pin ［ 2 ］ center 2 times to 3 times to pin ［ 4 ］ centre distance.Step is stepped on lever ［ 1 ］ and is made its pad ［ 4 ］ under pin ［ 2 ］ rotation, pressurized energy is in connecting rod ［ 5 ］, connecting rod ［ 5 ］ motion, it is descending to make slide block ［ 7 ］ go up the gathering sill that designs along the shell ［ 3 ］ of drawing by pin ［ 6 ］, compress the spring ［ 8 ］ between slide block and tappet, make tappet ［ 9 ］ obtain enough pressure, plastics of supporting by platen ［ 10 ］ or rubber pad ［ 11 ］ increase the stop frictional force to ground.Add the acting in conjunction of door leaf deadweight and make door leaf stop.Borrow the compressed elastic force of spring ［ 8 ］, the unevenness on ground is compensated.Because the inner space that limits of shell ［ 3 ］, after making the descending limit excessively of slide block ［ 7 ］, the corresponding position contact in the outside, connecting rod ［ 5 ］ upper end shell ［ 3 ］ inboard, be subjected to the restriction of shell ［ 3 ］, one dead point appears, center line and the pin ［ 2 ］ of connecting rod this moment ［ 5 ］, sell angle between the line of centres of ［ 6 ］ at 1 °～15 ° for well.So reliable lock.When need are removed stop, flip the slightly pedal end of pedal lever ［ 1 ］ of only using foot, spring ［ 8 ］ state that affranchises, because the effect of spring ［ 12 ］ sets back device, door leaf can freely rotate.

The utility model, used part is few, and is mostly stamping parts and little section bar, and manufacturing process is simple, so cost is not high, is easy to produce.And installation is also very convenient when using, and only needs be fixed on the angle of door leaf lower end away from folding with wood screw, and need not that other processing is done on ground can use, even ground is not at ordinary times, also can realize the location stopping function of door leaf reliably.

Claims

1, forms by shell, pedal lever, connecting rod, slide block, spring, tappet, platen and rubber cushion for one, be applied to the Stopping bolt on the building door, it is characterized in that: pedal lever [1] shell [3] connecting rod [5] slide block [7] connects with pin, between slide block [7] and the tappet [9] spring [8] is arranged.

2, the Stopping bolt of stipulating by claim 1, it is characterized in that: a pedal lever ［ 1 ］ with the steel sheet drawing, be connected with pin ［ 2 ］ on the shell ［ 3 ］ of drawing, the distance at pin ［ 2 ］ to pedal lever ［ 1 ］ upper footboard center is pin ［ 2 ］ 2～3 times to pin ［ 4 ］ centre distance.

3, the Stopping bolt of stipulating by claim 1, it is characterized in that: by the inner space that limits of shell ［ 3 ］, after making that slide block ［ 7 ］ is descending and crossing limit, corresponding position, the outside, connecting rod ［ 5 ］ upper end contacts shell ［ 3 ］ inboard, be subjected to the restriction of shell ［ 3 ］, a dead point occurs.

4, by the Stopping bolt of claim 1 regulation, it is characterized in that: when allowing its stop, the center line of connecting rod ［ 5 ］ and pin ［ 2 ］ to the angle between the line of centres of pin ［ 6 ］ at 1 ° to 15 °.
