[0002] A bank is a financial institution established in accordance with the law to operate monetary and credit businesses. It is the product of a commodity-money economy that has developed to a certain stage. What people usually refer to as a bank is a bank's business location, which is a physical area that provides customers with services such as cash deposits and withdrawals, securities and precious metal transactions, and payment and settlement, as well as office areas, warehouses, passages, etc. that are connected to it.

[0003] Currently, banks have very adequate security measures for funds and employees, but lack protection measures for ordinary customers. Once a robbery occurs in a bank, ordinary customers handling business in the bank's business hall will generally fall into panic, because there are few hiding places in the hall and it is impossible to hide completely. Even if the robbery itself does not cause physical harm to ordinary customers, the violence will also cause great psychological harm to ordinary customers.

[0004] The Chinese patent specification with application number: 202311222515.1 discloses a concealment system for bank robbery, which includes a water tank arranged under the ground foundation of the bank hall, an air outlet is provided on the sealing plate sealed on the upper port of the water tank, a sealing cover is provided on the air outlet, a groove is arranged on the outer surface of the sealing cover, and an air outlet channel is provided on the side wall of the groove. The water tank and the other end of each conduit joint are connected by a pipeline. When a robbery occurs in the bank, the gas can blow the dry ice in the dry ice storage tube into the water tank, and the dry ice will quickly release gas when it contacts the water, which can provide shelter for the customers in the hall, reduce the psychological harm of violent incidents to customers, and increase the sense of security. However, its air outlet channel is small and cannot quickly release a large amount of shielding gas in a short time; and the air outlet channel is exposed and easily blocked by debris; at the same time, water vapor will be emitted from the air outlet channel for a long time, making the bank hall humid. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic opening device for a smoke outlet based on a bank anti-robbery system to solve the problem that the air outlet channel of the concealed system in the prior art is small and a large amount of shielding gas cannot be quickly released in a short time.

[0006] In order to solve the above problems, the automatic opening device of the smoke outlet based on the bank anti-robbery system involved in the present invention adopts the following technical scheme: an automatic opening device of the smoke outlet based on the bank anti-robbery system, including a long box-shaped smoke-generating device, a smoke outlet is opened on the upper side of the smoke-generating device, a smoke outlet blocking structure is arranged in the smoke outlet, the smoke outlet blocking structure has a downwardly extending mounting barrel portion, the mounting barrel portion deviates from the axis of the smoke outlet blocking structure, a mounting shaft is fixedly arranged on the bottom wall of the smoke-generating device, the upper end of the mounting shaft is slidably guided into the mounting barrel portion, a torsion spring is slidably sleeved on the mounting shaft, one working end of the torsion spring is assembled with the mounting shaft to prevent rotation, and the other working end of the torsion spring presses on the mounting barrel portion.

[0007] The torsion spring is assembled on the installation shaft through a fixed ring to prevent rotation. The fixed ring is fixed by welding to the corresponding working end of the torsion spring. The fixed ring to prevent rotation sliding sleeve is arranged on the installation shaft.

[0008] The fixing ring and the installation shaft are assembled by sliding and stopping rotation through a sliding groove arranged on the installation shaft and a convex strip convexly arranged in the inner ring of the fixing ring.

[0009] A mounting notch is provided on the side wall of the mounting cylinder, and the corresponding working end of the torsion spring is pressed against the side wall of the mounting notch.

[0010] The installation notch is a U-shaped notch, and the opening of the installation notch faces downward.

[0011] The smoke outlet is in the shape of a countersunk hole, and the smoke outlet blocking structure is in the shape of a stepped shaft that fits in the smoke outlet.

[0012] The mounting tube is connected to the smoke outlet blocking structure at the edge, the upper end of the mounting tube is flush with the upper surface of the smoke outlet blocking structure, the lower end of the mounting tube extends downward, and the side of the smoke outlet is connected to form a notch that matches the mounting tube.

[0017] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the technical solution of the present invention is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0018] The specific embodiment of the automatic opening device of the cigarette outlet based on the bank anti-robbery system involved in the present invention is Figure 1-Figure 5 In the invention, a long box-shaped smoking device 1 is provided, and a smoke outlet 2 is provided on the upper side of the smoking device 1. The smoking device 1 is used to generate smoke under specific circumstances. The smoke outlet 2 provides an outlet for the generated smoke, so that the smoke can be easily dispersed from the smoking device 1. A smoke outlet blocking structure 3 is provided in the smoke outlet 2. The smoke outlet blocking structure 3 has a downwardly extending mounting barrel 4, which is fixed on the smoke outlet blocking structure 3 and deviates from the axis of the smoke outlet blocking structure 3. A mounting shaft 5 is fixedly provided on the bottom wall of the smoking device 1. The upper end sliding guide of the mounting shaft 5 extends into the mounting barrel 4. A torsion spring 6 is slidably sleeved on the mounting shaft 5. The torsion spring 6 is restricted in the mounting barrel 4 and can slide up and down in the inner barrel of the mounting barrel 4. One working end of the torsion spring 6 is assembled with the mounting shaft 5 to prevent rotation, and the other working end of the torsion spring 6 presses on the mounting barrel 4.

[0019] In the initial state, a certain torque is applied to the torsion spring 6. At this time, the smoke outlet blocking structure 3 is blocked on the smoke outlet 2. Affected by the side wall of the smoke outlet 2, the torque on the torsion spring 6 cannot be released. When smoke needs to be generated, the smoke generating device 1 generates a large amount of smoke. The smoke presses the smoke outlet blocking structure 3 to make the smoke outlet blocking structure 3 slide upward and separate from the smoke outlet 2. At this time, the torsion spring 6 is not interfered by the smoke outlet 2 and releases the torque. The working end of the torsion spring 6, which is fixed on the mounting shaft 5, does not move. The other working end, which is pressed on the mounting cylinder 4, rotates horizontally by a certain angle due to the release of the torque, thereby driving the smoke outlet blocking structure. The structure 3 rotates along the axis of the mounting cylinder 4 at a certain angle and deviates from the smoke outlet 2, so that the smoke outlet blocking structure 3 neither blocks the smoke outlet 2 nor blocks the flow path of the smoke, and the smoke can be dispersed in large quantities in a short time; when it is not necessary to generate smoke, first stop the smoke generating device 1 from generating smoke, and wait for the smoke to dissipate, the smoke outlet blocking structure 3 is no longer pressed by the smoke, and it slides upward under its own gravity and falls on the top wall of the smoke generating device 1, and the smoke outlet blocking structure 3 is rotated by external force to block the smoke outlet 2, and it can be restored to the initial state, and at the same time, a certain torque is synchronously applied to the torsion spring 6. Since the smoke outlet 2 is blocked by the smoke outlet blocking structure 3 in the non-smoking state, the smoke outlet 2 is closed and is not easily blocked by debris; at the same time, the water vapor in the smoke generating device 1 will not overflow from the smoke outlet 2 and make the bank hall humid.

[0020] Specifically, the torsion spring 6 is assembled on the installation shaft 5 by means of a fixing ring 7 to prevent rotation. The fixing ring 7 is restricted in the installation cylinder 4 and can slide up and down in the inner cylinder of the installation cylinder 4. The fixing ring 7 is welded and fixed to the corresponding working end of the torsion spring 6. The fixing ring 7 is anti-rotationally slidably sleeved on the installation shaft 5. In this way, the torsion spring 6 is assembled on the installation shaft 5 to prevent rotation and can slide up and down along the installation shaft 5.

[0021] Specifically, the fixing ring 7 and the mounting shaft 5 are assembled by sliding and stopping rotation through a sliding groove (not shown in the figure) provided on the mounting shaft 5 and a convex strip (not shown in the figure) convexly provided in the inner ring of the fixing ring 7. The sliding and stopping rotation cooperation of the sliding groove and the convex strip belongs to the prior art. An axial sliding groove is provided on the side wall of the mounting shaft 5, and a radial convex strip is convexly provided in the inner ring of the fixing ring 7. Through the cooperation of the convex strip and the sliding groove, the fixing ring 7 is sleeved on the mounting shaft 5 and can slide up and down along the mounting shaft 5.

[0022] Specifically, a mounting notch 8 is provided on the side wall of the mounting cylinder 4, and the corresponding working end of the torsion spring 6 presses against the side wall of the mounting notch 8. When the torsion spring 6 releases the torque, it presses against the side wall of the mounting notch 8 to make the mounting cylinder 4 rotate horizontally at a certain angle, thereby driving the smoke outlet blocking structure 3 to rotate along the axis of the mounting cylinder 4 at a certain angle.

[0023] Specifically, the installation notch 8 is a U-shaped notch, and the opening of the installation notch 8 faces downward.

[0024] Specifically, the smoke outlet 2 is in the shape of a countersunk hole, and the smoke outlet blocking structure 3 is in the shape of a stepped shaft that fits in the smoke outlet 2. In this way, in the initial state, the upper end surface of the smoke outlet blocking structure 3 is flush with the upper end of the smoke outlet 2, and the smoke outlet blocking structure 3 is hidden in the top wall of the smoke generating device 1, which is neat and beautiful, and has no sanitary dead corners, which is easy to clean or clear.

[0025] Specifically, the mounting cylinder 4 is connected to the smoke outlet blocking structure 3 at the edge, that is, the mounting cylinder 4 is fixed on the side wall of the smoke outlet blocking structure 3, the upper end of the mounting cylinder 4 is flush with the upper surface of the smoke outlet blocking structure 3, the lower end of the mounting cylinder 4 extends downward, and the side edge of the smoke outlet 2 is connected to form a notch that matches the mounting cylinder 4, and the notch is used to accommodate the top wall of the mounting cylinder 4.

[0026] Specifically, the bottom of the mounting cylinder 4 is provided with a bottom wall that blocks the fixing ring 7 from sliding down, and a small diameter hole is opened on the bottom wall. The mounting shaft 5 cooperates with the small diameter hole at the bottom of the mounting cylinder 4 and is slidably guided by the mounting cylinder 4. The upper end sliding guide of the mounting shaft 5 extends into the mounting cylinder 4, and the lower end thereof extends out of the mounting cylinder 4 through the small diameter hole.

[0027] The torsion spring in this embodiment is assembled on the mounting shaft by means of a fixing ring to prevent rotation. This is an optimized technical solution. In other embodiments, the fixing ring may not be provided. Instead, an axial sliding groove may be opened on the side wall of the mounting shaft so that one end of the torsion spring slides up and down into the sliding groove. The torsion spring is assembled on the mounting shaft by means of this end to prevent rotation.

[0028] In this embodiment, the fixing ring and the mounting shaft are assembled by sliding and stopping rotation through a sliding groove arranged on the mounting shaft and a convex strip protruding from the inner ring of the fixing ring. In other embodiments, a through groove can be opened on the inner wall of the fixing ring, and an axially extending convex strip can be protruded on the outer wall of the mounting shaft. The sliding and stopping rotation assembly of the fixing ring and the mounting shaft is achieved through the sliding cooperation between the through groove and the convex strip.

[0029] In this embodiment, an installation notch is provided on the side wall of the installation cylinder, which is an optimized technical solution. In other embodiments, the installation notch may not be provided, but an axially extending convex strip may be provided on the inner wall of the installation cylinder, and the corresponding working end of the torsion spring is pressed against the side wall of the convex strip.

[0030] In this embodiment, the installation notch is a U-shaped notch, and in other embodiments, the installation notch may also be a straight notch.

[0031] In this embodiment, the smoke outlet is in the shape of a countersunk hole, which is an optimized technical solution. In other embodiments, the smoke outlet may also be a straight hole, and a lower limit structure is provided to prevent the smoke outlet blocking structure from falling down.

[0032] In this embodiment, the installation cylinder is connected to the smoke outlet blocking structure at the edge, which is an optimized technical solution. In other embodiments, the installation cylinder can also be connected to the smoke outlet blocking structure in the middle part away from the axis of the smoke outlet blocking structure.

[0033] In this embodiment, the mounting shaft cooperates with the mounting cylinder through the small diameter hole at the bottom of the mounting cylinder to slide and guide. In other embodiments, the small diameter hole can also be replaced by a large diameter hole, but the radius of the large diameter hole should be smaller than the outer diameter of the fixing ring.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
