Description

Technical Field

[0001] The invention relates to the technical field of police safety devices, in particular to a door blocker. Background Art

[0002] The door stopper is used to prevent the door from closing or opening. Depending on the practical situation, it can be used to keep the door open or to keep the door closed so that it cannot be easily opened. It is widely used in daily life.

[0003] Door blockers are often used as door-breaking tools during arrests in the police field, so as to facilitate smooth and rapid door-breaking. At present, violent door-breaking is often used, which will give criminals in the room time to destroy evidence or even the opportunity to escape by jumping out of the window. What's worse, it will give criminals the opportunity to fight back and cause huge losses. At present, there is no better tool to allow criminals to successfully break through the door without being noticed. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is: how to provide a door blocker that can keep the door body from closing after the criminals open the door, so as to achieve the effect of successfully breaking the door.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A door stopper comprises a shell, a door stop pressure rod and an energy storage element, wherein the energy storage element is installed in the shell, the door stop pressure rod passes through the shell and is connected to the energy storage element, the energy storage element can be used to drive the door stop pressure rod to rotate and stop, and a quick connection component is also installed on the outside of the shell.

[0007] In this way, when in use, the housing is installed on the door body through the quick connection component. When the door body is an outward-opening door, the door-blocking pressure rod is located above the door body. When the door body is an inward-opening door, the door-blocking pressure rod faces the side of the door body and the side where the door body is hinged to the wall. The energy storage element stores energy. After the door body is opened, the energy storage element releases energy to drive the door-blocking pressure rod to rotate, so that the door-blocking pressure rod rotates to one side or above the door body, or rotates to the room. When the energy storage element releases energy, it drives the door-blocking pressure rod to rotate only in one direction, so as to better achieve the door-blocking effect. When it needs to be reused, it only needs to manually reset the energy storage element and re-store energy.

[0008] As an optimization, the energy storage element includes a transmission shaft, an energy storage shaft, a rotating shaft, a torsion spring, an energy storage unit and an energy release unit. The door-blocking pressure rod is fixedly connected to the transmission shaft. The transmission shaft is provided with a through hole along the axial direction. The torsion spring is installed in the through hole. The energy storage shaft and the rotating shaft are rotatably connected to the shell through the energy storage unit and the energy release unit respectively. The energy storage shaft and the rotating shaft are fixedly connected to both ends of the torsion spring respectively, and the end of the energy storage shaft is rotatably installed on one end of the transmission shaft, and the other end of the transmission shaft is fixedly connected to the end of the rotating shaft.

[0009] In this way, in the initial state, the energy release element drives the door-blocking pressure rod to be in the initial state by rotating the shaft, that is, the state of not contacting the door body. After the shell is installed on the door body, the energy storage unit stores energy, and drives the torsion spring to rotate and store energy through the energy storage shaft. After the energy storage is completed, the energy release unit releases the restriction on the rotating shaft. When the door body is opened, the torsion spring releases energy, driving the door-blocking pressure rod to rotate to the side or above the door body or inside the room, thereby achieving the door-blocking effect.

[0010] As an optimization, the energy storage unit includes an energy storage one-way bearing, the end of the energy storage shaft facing away from the transmission shaft is fixedly connected to the inner ring of the energy storage one-way bearing, and the outer ring of the energy storage one-way bearing is fixedly connected to the housing through a connecting block.

[0011] In this way, the energy storage shaft rotates, driving the torsion spring to rotate to achieve energy storage. The energy storage one-way bearing can only rotate in one direction, so after the torsion spring stores energy, the energy storage shaft cannot drive the torsion spring to reset, which has a self-locking effect.

[0012] As an optimization, a toggle assembly is provided at the end of the energy storage shaft. The toggle assembly drives the energy storage shaft to rotate to achieve energy storage. Specifically, a card slot is provided at the end of the energy storage shaft, and the card block is inserted into the card slot to drive the energy storage shaft to rotate; or the outer end of the energy storage shaft is located outside the connecting block, and the energy storage shaft can be rotated with a wrench.

[0013] As an optimization, the energy release unit includes an energy release one-way bearing, the end of the rotating shaft facing away from the transmission shaft is fixedly connected to the inner ring of the energy release one-way bearing, the rotation direction of the energy release one-way bearing is opposite to the rotation direction of the energy storage one-way bearing, and the outer ring of the energy release one-way bearing is detachably fixedly connected to the shell through a reset block; the energy release unit also includes a quick release mechanism, which is used to connect the shell and the rotating shaft.

[0014] In this way, after the torsion spring accumulates energy, the fixed top screw is rotated with a wrench to release the restriction on the rotating shaft. Under the torsion of the torsion spring, the door-blocking pressure plate rotates to fit the door frame. When the door is opened, the torsion spring releases energy, and the door-blocking pressure rod rotates to the top of the door body, and even extends into the room to perform the door-blocking operation. After use, before the next use, the reset block is disassembled and rotated. The reset block drives the energy-releasing one-way bearing to rotate, and then drives the transmission shaft and the door-blocking pressure rod to rotate and reset, and then the reset block is fixed for the next use.

[0015] As an optimization, the door-blocking pressure rod is in an "L" shape, which can be better overlapped above the door body, and even extended into the room, so as to better block the door.

[0016] As an optimization, a roller is rotatably mounted on the free end of the door-blocking pressure rod, which can reduce the resistance of the door-blocking pressure rod when it rotates, improve the smoothness, and further improve the door-blocking efficiency.

[0017] As an optimization, the door-blocking pressure rod is made of metal material, which can better bear pressure, with small deformation and low fracture rate.

[0018] As an optimization, a data collector and an alarm are also included, and a chip connected to the data collector and the alarm signal is installed in the shell. In this way, after the door-blocking pressure rod rotates driven by the energy released by the energy storage element, the data collector collects the movement and converts it into an electrical signal and transmits it to the alarm through wireless transmission, so that the case handlers can take timely action.

[0019] In summary, the door blocker disclosed in the present invention has the following beneficial effects: the door blocker provided by the present solution is placed on the door body, so as to block the door when the people inside the room open the door by themselves, thereby avoiding the commotion caused by the investigators breaking the door violently, and achieving smooth entry and arrest. The present solution has strong concealment and high strength, and can delay the closing of the door body, making it impossible to close, thereby ensuring the safety and efficiency of the arrest.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-6 A door stopper comprises a shell 1, a door stop pressure rod 11 and an energy storage element. The energy storage element is installed in the shell 1. The door stop pressure rod 11 passes through the shell 1 and is connected to the energy storage element. The energy storage element can be used to drive the door stop pressure rod 11 to rotate and stop. A quick connection component is also installed on the outside of the shell 1.

[0028] In this way, when in use, the housing is installed on the door body through the quick connection component. When the door body is an outward-opening door, the door-blocking pressure rod is located above the door body. When the door body is an inward-opening door, the door-blocking pressure rod faces the side of the door body and the side where the door body is hinged to the wall. The energy storage element stores energy. After the door body is opened, the energy storage element releases energy to drive the door-blocking pressure rod to rotate, so that the door-blocking pressure rod rotates to one side or above the door body, or rotates to the room. When the energy storage element releases energy, it drives the door-blocking pressure rod to rotate only in one direction, so as to better achieve the door-blocking effect. When it needs to be reused, it only needs to manually reset the energy storage element and re-store energy.

[0029] In this embodiment, the energy storage element includes a transmission shaft 12, an energy storage shaft 13, a rotating shaft 14, a torsion spring 15, an energy storage unit and an energy release unit. The door-blocking pressure rod 11 is fixedly connected to the transmission shaft 12. The transmission shaft 12 is axially penetrated with a through hole. The torsion spring 15 is installed in the through hole. The energy storage shaft 13 and the rotating shaft 14 are respectively rotatably connected to the housing 1 through the energy storage unit and the energy release unit. The energy storage shaft 13 and the rotating shaft 14 are respectively fixedly connected to both ends of the torsion spring 15, and the end of the energy storage shaft 13 is rotatably installed on one end of the transmission shaft 12, and the other end of the transmission shaft 12 is fixedly connected to the end of the rotating shaft 14.

[0030] In this way, in the initial state, the energy release element drives the door-blocking pressure rod to be in the initial state by rotating the shaft, that is, the state of not contacting the door body. After the shell is installed on the door body, the energy storage unit stores energy and drives the torsion spring to rotate and store energy through the energy storage shaft 13. After the energy storage is completed, the energy release unit releases the restriction on the rotating shaft. When the door body is opened, the torsion spring releases energy and drives the door-blocking pressure rod to rotate to one side or above the door body or inside the room to achieve the door-blocking effect.

[0031] In this embodiment, the energy storage unit includes an energy storage one-way bearing 16, and the end of the energy storage shaft 13 facing away from the transmission shaft 12 is fixedly connected to the inner ring of the energy storage one-way bearing 16, and the outer ring of the energy storage one-way bearing 16 is fixedly connected to the shell 1 through a connecting block 10.

[0032] In this way, the energy storage shaft 13 rotates, driving the torsion spring to rotate to store energy. The energy storage one-way bearing can only rotate in one direction, so after the torsion spring stores energy, the energy storage shaft 13 cannot drive the torsion spring to reset, which has a self-locking effect. Specifically, the energy storage unit can also be a ratchet.

[0033] In this embodiment, a toggle assembly 17 is provided at the end of the energy storage shaft 13. The toggle assembly drives the energy storage shaft 13 to rotate to achieve energy storage. Specifically, a card slot is provided at the end of the energy storage shaft 13, and the card block is inserted into the card slot to drive the energy storage shaft 13 to rotate; or the outer end of the energy storage shaft 13 is located outside the connecting block, and the energy storage shaft 13 can be rotated using a wrench.

[0034] In this embodiment, the energy release unit includes an energy release one-way bearing 18, and the end of the rotating shaft 14 facing away from the transmission shaft 12 is fixedly connected to the inner ring of the energy release one-way bearing 18. The rotation direction of the energy release one-way bearing 18 is opposite to the rotation direction of the energy storage one-way bearing 16. The outer ring of the energy release one-way bearing 18 is detachably fixedly connected to the shell 1 through a reset block 19; the energy release unit also includes a quick release mechanism, which is used to connect the shell (1) and the rotating shaft (14).

[0035] In this way, after the torsion spring accumulates energy, the quick release mechanism is triggered to release the restriction on the rotating shaft. Under the torsion of the torsion spring, the door-blocking pressure plate rotates to fit the door frame. When the door is opened, the torsion spring releases energy, and the door-blocking pressure rod rotates to the top of the door body, and even extends into the room to perform the door-blocking operation. After use, before the next use, the reset block is removed and the reset block is rotated. The energy-releasing one-way bearing is driven to rotate through the reset block, and then the transmission shaft and the door-blocking pressure rod are driven to rotate and reset, and then the reset block is fixed for the next use. Specifically, the energy release unit can also be a ratchet.

[0036] Specifically, the release mechanism is a latch 3, a socket 31 is provided on the rotating shaft opposite to the latch 3, a through hole is provided on the shell 1 opposite to the socket, and the latch 3 is arranged in the socket 31 and the through hole; when in use, the release action is completed by quickly pulling out the latch, so that the rotating shaft can rotate relative to the shell, and complete the rotation under the action of the torsion spring when the door is opened.

[0037] Specifically, the release mechanism can also be a fixed top screw 2. The shell 1 is provided with a threaded hole corresponding to the rotating shaft 14. The fixed top screw 2 is threadedly engaged in the threaded hole. When in use, the fixed top screw presses the rotating shaft to lock it. When release is required, the fixed top screw is unscrewed to release the rotating shaft.

[0038] In this embodiment, the door-blocking pressure rod 11 is in an "L" shape. It can be better overlapped above the door body, and even extend into the room, so as to better block the door. Specifically, the door-blocking pressure rod can also be in a rod shape or an arc shape.

[0039] In this embodiment, the free end of the door-blocking pressure rod 11 is rotatably mounted with a roller 21. The resistance when the door-blocking pressure rod 11 rotates can be reduced, the smoothness is improved, and the door-blocking efficiency is further improved.

[0040] In this embodiment, the door-blocking pressure rod 11 is made of metal material, which can better withstand pressure, has small deformation and low fracture rate.

[0041] In this embodiment, a data collector and an alarm are also included, and a chip connected to the data collector and the alarm signal is installed in the shell.

[0042] In this way, after the door-blocking pressure rod rotates driven by the energy released by the energy storage element, the data collector collects the movement and converts it into an electrical signal and transmits it to the alarm through wireless transmission, so that the case handlers can take action in time.

[0043] Specifically, the data collector includes but is not limited to a photoelectric switch arranged in the housing, and may also be an infrared transmitter.

[0044] Specifically, the alarm is a photoelectric alarm to avoid alerting criminals by producing an alarm sound.

[0045] Specifically, the quick connection component includes an electromagnet installed on the outside of the housing 1. The electromagnet has a strong magnetic force and has a good adsorption effect on metal door bodies such as anti-theft doors, so as to be used for stable connection.

[0046] Specifically, the quick connection component can also be a magnetic seat installed on the outside of the shell 1. Under the premise of ensuring the magnetic force, static adsorption is achieved by rotating the switch to avoid the door body from being hit and making noise due to excessive magnetic force during the contact between the sticker and the door body.

[0047] Specifically, the quick connection component can also be a strong glue, including using 3M glue or other adhesives to achieve the connection between the shell and the door body, which is convenient for achieving a stable connection with the non-metallic body, all of which fall within the scope of protection required by this patent.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
