Description

A kind of door opener

Technical field

The present invention relates to a kind of door openers.

Background technique

Existing mode of forcing open the door mainly has：Human body is rushed open, is broken door using sledgehammer or hammer of forcing open the door, these modes of forcing open the door One side strength it is smaller, need multiple impact that could break door；On the other hand, sledgehammer is relatively difficult to be hammered on tapered end, It is not high to hammer precision.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of door openers, can realize quick and precisely by lock pin sliding trackle Quickly force open the door.

In order to solve the above-mentioned technical problem, the technical scheme is that：

A kind of door opener, including telescopic rod have been respectively articulated with one piece of skid plate at telescopic rod both ends, have been fixedly connected on telescopic rod Have axle sleeve, axle sleeve side is connected with wheel box, in axle sleeve be equipped with a spur rack, spur rack both ends respectively with flat chisel and hammer block It is fixedly connected, is equipped with shaft and non-return mechanism in wheel box, ratchet and one and spur rack meshed gears are installed in shaft, The non-return mechanism includes the pawl of spring and axis connection in wheel box, and both ends of the spring is born against in pawl and wheel box inner wall On, pawl one end is entrapped on ratchet.

The telescopic rod includes mandril, is equipped with hydraulic cylinder in mandril one end, hydraulic cylinder passes through hydraulic self-locking circuit and hand Press pump connection.

The skid plate includes plate body, and plate body one end has the inserted block of a triangle, and rubber pad is equipped on plate body end face.

Spring is cased with outside spur rack, both ends of the spring bears against on wheel box and hammering block, is equipped with and opens in box body side Mouthful, pull rod is equipped in opening, pull rod one end is fixedly connected with pawl, and other end is fixedly connected with one piece of pulling block.

The beneficial effects of the invention are as follows：After telescopic rod is fixed on doorframe, hammering block is tapped using sledgehammer, to push flat chisel Move ahead, accurately lock pin can be chopped off using forward flat chisel, realize quick dismantling on the door, at the same time, ratchet and only Going back to mechanism can prevent flat chisel from springing back while flat chisel moves ahead, and frictional force when reducing secondary hammering and ease off, greatly Improve forcible entry efficiency.

Detailed description of the invention

Following further describes the present invention with reference to the drawings：

Fig. 1 is overlooking structure diagram of the invention,

Fig. 2 is partial profile structure of the invention,

Fig. 3 is partial profile structure of the invention,

In figure：Doorframe 1, door-plate 2, telescopic rod 3, skid plate 4, spur rack 5, axle sleeve 6, wheel box 7, gear 8, non-return mechanism 9, hand Press pump 10, hydraulic self-locking circuit 11, lock core 21, lock pin 22, lock housing 23, hydraulic cylinder 31, mandril 32, inserted block 41, rubber pad 42, hammer Hit block 51, flat chisel 52, shaft 81, ratchet 82, pawl 91, pull rod 92, pulling block 93.

Specific embodiment

As shown in fig. 1 to 4, a kind of door opener, including telescopic rod 3 have been respectively articulated with one piece of skid plate at 3 both ends of telescopic rod 4, axle sleeve 6 is fixedly connected on telescopic rod 3,6 side of axle sleeve is connected with wheel box 7, a spur rack 5 is equipped in axle sleeve 6, directly 5 both ends of rack gear are fixedly connected with flat chisel 52 and hammering block 51 respectively, shaft 81 and non-return mechanism 9 are equipped in wheel box 7, in shaft 81 On ratchet 82 and one and 5 meshed gears 8 of spur rack are installed, the non-return mechanism 9 includes spring and axis connection in wheel box 7 Interior pawl 91, both ends of the spring are born against on pawl 91 and wheel 7 inner wall of box, and 91 one end of pawl is entrapped on ratchet 82.

Application method and working principle of the invention be：

Telescopic rod 3 is installed on doorframe 1 by the first step, the upper and lower position of telescopic rod 3 is adjusted, so that flat chisel 52 can be directed at lock 21 side lock pin 22 of core；

Second step, push flat chisel 52 against door-plate 2 on, then using sledgehammer hammer repeatedly hammer block 51, to push flat chisel 52 It enters in lock housing 23 across door-plate 2, then chops lock pin 22 off.

During flat chisel 52 moves ahead, ratchet 82 and non-return mechanism 9 can prevent flat chisel 52 from springing back, and reduce secondary hammering When frictional force and ease off, improve forcible entry efficiency；On the other hand, due to the guiding role of axle sleeve 6, in 52 energy of flat chisel Enough going straight aheads, can accurately chop lock pin 22 off.

The telescopic rod 3 includes mandril 32, is equipped with hydraulic cylinder 31 in 32 one end of mandril, hydraulic cylinder 31 passes through hydraulic self-locking Circuit 11 is connect with handlance 10.Hydraulic self-locking circuit 11 includes two hydraulic control one-way valves and a handle type three-position four-way valve structure At, in use, three-position four-way valve can be moved to middle position after hydraulic cylinder 31 pushes two pieces of skid plates 4 in doorframe 1, utilization The excellent sealing of hydraulic control one-way valve, it is ensured that hydraulic cylinder 31 jacked after stability, avoid hydraulic cylinder 31 after being impacted Oil leak and cause telescopic rod 3 to fall.

The skid plate 4 includes plate body, and plate body one end has the inserted block 41 of a triangle, and rubber is equipped on plate body end face Pad 42.The inserted block 41 of triangle is inserted into the gap between door-plate 2 and doorframe 1, and the steady of telescopic rod 3 can be improved first Qualitative, next can use 41 inclined-plane of inserted block and pushes out door-plate 2, reduces the shifting amount between door-plate 2 and doorframe 1, prevents Door-plate 2 is shaken in hammering, improves the validity when shovel of flat chisel 52 is hit.

Spring is cased with outside spur rack 5, both ends of the spring bears against on wheel box 7 and hammering block 51, sets in box body side There is opening, be equipped with pull rod 92 in opening, 92 one end of pull rod is fixedly connected with pawl 91, and other end is fixed with one piece of pulling block 93 to be connected It connects.After pulling pull rod 92, pawl 91 is detached from ratchet 82, and spring pushes spur rack 5 to spring back, 5 Quick-return of spur rack is enable to arrive It is in situ, to operate people's secondary operation.
