Description

Windproof self-locking mechanical door stopper

Technical Field

The utility model relates to a house ornamentation facility field, in particular to prevent wind auto-lock mechanical door stopper.

Background

The door stopper is generally divided into two parts, which are respectively mounted on the door and the wall, for fixing the position of the door and preventing the door from being closed by wind or other accidents. Most of door stoppers in the current market are magnetic attraction type door stoppers, and the magnetic force of the magnetic attraction type door stopper gradually decreases as the service life of the magnetic attraction type door stopper increases; meanwhile, when wind power is large, the magnetic door stopper cannot fix the door plate at all, and the effect is poor.

Disclosure of Invention

The utility model discloses to the shortcoming of current magnetism type door-inhale, provide a prevent wind auto-lock mechanical door-inhale. The door stopper can be automatically locked when the door is close to the wall, so that the door plate is firmly fixed, and the door stopper cannot be unlocked under the condition of not damaging the door stopper no matter how much wind exists; by lightly pushing the door plate towards the wall, the door stopper can be automatically unlocked.

In order to realize the purpose, the utility model adopts the technical scheme that a windproof self-locking mechanical door stopper is provided. The door stopper comprises a suction seat and a collision head; the suction seat is arranged on a wall and consists of a base, a spring, a first ratchet wheel, a second ratchet wheel, a lock catch and a shell; the collision head is arranged on the door and consists of a clamping seat, a collision head, a bolt and a nut.

When the door is pushed to the wall by a hand, the collision head penetrates through the lock catch to push the first ratchet wheel, the first ratchet wheel pushes the second ratchet wheel to compress the spring, the hand is loosened, the spring and the fixed shaft on the base act together to enable the second ratchet wheel to rotate, so that the lock catch connected and fixed on the second ratchet wheel is driven to rotate and just clamp the collision head, at the moment, the door stopper is in a locking state, and the position of the door plate is fixed. The door plate is slightly pushed towards the wall by a hand again, the collision head props against the first ratchet wheel to push the second ratchet wheel to compress the spring, the hand is loosened at the moment, the second ratchet wheel rotates again under the combined action of the spring and the fixed shaft on the base, the lock catch rotates along with the rotation, the door stopper is in an unlocking state at the moment, and the door plate can move freely.

The utility model discloses a prevent wind auto-lock mechanical door-inhale and be not afraid of strong wind, buffering effect is good, reduces the collision of door and wall, and it is easy and simple to handle simultaneously, only need nudge the door plant with regard to lockable or unblock. The door stopper is firm and durable in structure, simple and easy to machine parts, and suitable for large-scale production.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The door stopper mainly comprises two parts of a suction seat and a collision head, and the structures of the parts of the suction seat and the collision head are shown in figures 1 and 2. The suction seat comprises a shell 1, a lock catch 2, a first ratchet wheel 3, a second ratchet wheel 4, a spring 5 and a base 6; a fixed shaft 602 is arranged on the base 6, and a sliding rail 601 is arranged at the top end of the fixed shaft 602; the spring 5 is sleeved on the fixed shaft 602, the second ratchet 4 slides along the slide rail 601 and the fixed shaft 602, and can rotate around the fixed shaft 602 after the second ratchet sliding groove 402 is separated from the slide rail 601; the lock catch 2 is fixedly connected with the second ratchet wheel 4; the first ratchet wheel 3 slides between the lock catch 2 and the second ratchet wheel 4 along the slide rail 601 and the fixed shaft 602, the first ratchet wheel slide groove 301 on the first ratchet wheel 3 is just matched with the slide rail 601, the first ratchet wheel tooth 302 on the first ratchet wheel 3 is just matched with the second ratchet wheel tooth 403 on the first ratchet wheel 3, and the second ratchet wheel 4 can rotate around the fixed shaft 602 for a certain angle after the second ratchet wheel slide groove 402 is separated from the slide rail 601 through the action of force among the first ratchet wheel tooth 302, the second ratchet wheel tooth 403 and the spring 5. The assembly of the suction holder is shown in fig. 3.

The collision head consists of a clamping seat 7, a bolt 8, a collision head 9 and a nut 10; the clamping seat 7 is provided with two clamping blocks 701, and the clamping blocks 701 are provided with clamping block screw holes 702; a fixing block 901 is arranged on the ram 9, and a fixing block screw hole 903 is arranged on the fixing block 901; the clamping block 701 can just clamp the fixing block 901, and the bolt 8 just penetrates through the clamping block screw hole 702 and the fixing block screw hole 903; when the nut 10 is loosened, the fixing block 901 can rotate around the bolt 8, and by adjusting the angle of the fixing block 901, no matter how far the door spindle is away from the wall body, the axis of the collision head 9 can be ensured to be coincident with the axis of the fixing shaft 602 when the collision head 9 is contacted with the suction seat; by the structure, the door stopper with one specification can be used for adapting to the distances between different door shafts and the wall body.

The working principle of the utility model is as shown in fig. 4 to fig. 9:

the collision head is arranged on the door, and the suction seat is arranged on the wall. When the door is close to the wall, the collision head is driven to approach the door stopper, and fig. 4 shows a state when the collision head 9 is not in contact with the suction seat. Fig. 5 is a left side view of the suction seat in the state of fig. 4, in which the striking pin 902 of the striking head 9 is misaligned with the catching pin 201 of the lock catch 2, and the striking head 9 just passes through the lock catch 2.

When the door moves to the position of fig. 6, the ram 9 pushes the first ratchet 3 and then the second ratchet 4 to compress the spring 5, and the second ratchet runner 402 leaves the slide rail 601, and the second ratchet 4 rotates around the fixed shaft 602 by a certain angle under the force between the first ratchet teeth 302, the second ratchet teeth 403 and the spring 5. At the moment, the hand is loosened, the first ratchet wheel 3 does not exert a force on the second ratchet wheel 4 any more, the second ratchet wheel 4 rotates for a certain angle again under the action of the spring 5 and the sliding rail 601, so that the second ratchet wheel sliding groove 402 just slides into the sliding rail 601, and stops sliding under the action of the limiting block 401 and the shell 1; the door stopper is locked at this time as shown in fig. 7. Because the lock catch 2 is connected and fixed on the second ratchet wheel 4, when the second ratchet wheel 4 rotates, the lock catch 2 rotates along with the second ratchet wheel 4; fig. 8 is a left side view of the suction seat in the state of fig. 7, when the latch 201 just can block the striker 902, the door stopper is in the locked state, and the door panel is fixed and cannot be blown by wind to close the door.

When the door stopper needs to be unlocked, the door panel is pushed lightly by hand, as shown in fig. 9, the striker 9 is driven by the door to push the first ratchet 3 and then push the second ratchet 4 to compress the spring 5, at this time, the second ratchet sliding groove 402 slides out of the sliding rail 601, and simultaneously, under the action of the forces among the first ratchet teeth 302, the second ratchet teeth 403 and the spring 5, the second ratchet 4 rotates around the fixed shaft 602 for a certain angle. At this time, the hand is released, the second ratchet wheel 4 rotates again under the action of the spring 5 and the slide rail 601 until the second ratchet wheel sliding groove 402 slides into the slide rail 601 again, and then the second ratchet wheel 4 stops rotating; the door is sucked back to the unlocked state, i.e., the state of fig. 4.

The above description is only an embodiment of the present invention, and all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, should be included in the protection scope of the present invention.
