Description

Technical Field

[0001] The utility model belongs to the technical field of rolling shutter door structures, in particular to an anti-theft protection type rolling shutter door. Background Art

[0002] The common rolling shutter doors are mainly composed of a motor, a rotating shaft, and a door body. The lower end of the door body generally needs to be locked with a fixed structure on the ground, and the two sides of the door body generally need to enter the vertical slots to ensure that the side positions are difficult to pry open. The vertical slots can be directly opened on the wall where the rolling shutter door is installed, or provided by the frame structure of the rolling shutter door.

[0003] On the other hand, there are more intelligent anti-theft rolling shutter doors on the market. Compared with ordinary rolling shutter doors, the biggest difference is that they are equipped with additional proximity switches and alarms. The basic principle of anti-theft rolling shutter doors is that when the door is pried open and pulled upward, the proximity switch is triggered, which in turn triggers the alarm to achieve a certain anti-theft effect.

[0004] For example, a Chinese utility model patent with patent announcement number CN217872572U and announcement date 2022.11.22 discloses an anti-theft rolling shutter door, including a left door frame, a right door frame and a rolling shutter door, a top box is installed on the top of the left door frame and the right door frame, and movable blocks are fixedly connected to the two side surfaces of the bottom of the rolling shutter door, and the two movable blocks are respectively slidably connected to the inside of the left door frame and the right door frame, and a lifting screw is rotatably connected to the inside of the right door frame, and a lifting block is threadedly connected to the lifting screw, one end of the lifting block is hinged with a rotating block through a hinge, and a proximity switch is installed on the lifting block.

[0005] The anti-theft rolling shutter door in this utility model patent has the following structural principles and advantages: when the rolling shutter door is violently lifted up, one end of the movable block squeezes the rotating block at one end of the lifting block and flips close to the proximity switch. The proximity switch sends an electrical signal to the alarm mechanism to issue an alarm reminder, warning that an outsider has broken in, thereby improving the safety of the rolling shutter door.

[0006] However, the anti-theft rolling shutter door has at least the following two shortcomings in actual use, which are also the technical problems to be solved by the utility model, namely:

[0007] 1. The proximity switch is only set on one side of the rolling door. When the other side is slightly pulled up to form a small gap that a person can crawl through, the alarm and anti-theft function will be completely ineffective;

[0008] 2. Its anti-theft function is of a passive type and lacks certain active anti-theft functions, such as the function that the rolling shutter door itself is difficult to be pried open upwards.

[0009] Therefore, in summary, there is an urgent need for a new anti-theft rolling shutter door with active anti-theft function and more comprehensive passive anti-theft alarm function. Utility Model Content

[0010] The utility model provides an anti-theft protection type rolling shutter door, which can be achieved by arranging side vertical plate units, top plate box units, limit vertical rods, motors, rotating shafts, door bodies, proximity switches, alarms, and engaging counterweight plate units on ground fixed slot plate units, so that: 1. no matter which end of the bottom edge of the door body is pried open upwards, the proximity switch and the alarm can be triggered, thereby ensuring the efficiency and comprehensiveness of the passive anti-theft alarm function; 2. the engaging counterweight plate unit and the ground fixed slot plate unit can be locked, and more importantly, the two can be fully engaged, and the engaging gap is vertical, so it is difficult to pry the door body upwards, thereby ensuring the effectiveness of the active anti-theft function.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problems is: a theft-proof protection type rolling shutter door, the structure of which includes a motor, a rotating shaft, a door body, a proximity switch, and an alarm, and also includes a ground fixed slot plate unit, two side vertical plate units arranged on the ground fixed slot plate unit and used to install the proximity switch, a top plate box unit arranged on the two side vertical plate units and used to install the motor, the rotating shaft and the alarm, a limiting vertical rod arranged in the side vertical plate unit, and a locking counterweight plate unit arranged on the bottom edge of the door body, sleeved with the limiting vertical rod, and used to insert the ground fixed slot plate unit and trigger the proximity switch.

[0012] A further preferred technical solution is that the ground-fixed slot plate unit comprises a rectangular plate, and a rectangular slot arranged on the upper surface of the rectangular plate and used for inserting and engaging the engaging counterweight plate unit.

[0013] A further preferred technical solution is that the ground-fixed slot plate unit further includes a lock installation slot arranged on the upper surface or side surface of the rectangular plate.

[0014] A further preferred technical solution is that the ground-fixed slot plate unit also includes a pad for filling the rectangular slot when the rolling door is opened.

[0015] A further preferred technical solution is that the side vertical plate unit includes a vertical plate arranged on the upper surface of the rectangular plate and having a U-shaped cross-section, and a circular groove arranged on the inner side of the vertical plate and used to install the proximity switch.

[0016] A further preferred technical solution is that 3-5 proximity switches arranged vertically are provided on a single vertical plate.

DETAILED DESCRIPTION

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-7 As shown, a theft-proof protection type rolling shutter door has a structure including a motor 11, a rotating shaft 12, a door body 13, a proximity switch 14, and an alarm 15, and also includes a ground fixed slot plate unit 1, two side vertical plate units 2 arranged on the ground fixed slot plate unit 1 and used to install the proximity switch 14, a top plate box unit 3 arranged on the two side vertical plate units 2 and used to install the motor 11, the rotating shaft 12 and the alarm 15, a limiting vertical rod 4 arranged in the side vertical plate unit 2, and a locking counterweight plate unit 5 arranged on the bottom edge of the door body 13 and sleeved with the limiting vertical rod 4 and used to insert the ground fixed slot plate unit 1 and trigger the proximity switch 14.

[0034] In this embodiment, the door body 13 is made of high-strength steel or high-strength aluminum alloy to ensure sufficient structural strength. Its top edge is fixed on the rotating shaft 12, and its bottom edge is locked and connected to the ground fixed slot plate unit 1 through the engaging counterweight plate unit 5. At this point, the rolling door can be opened and closed normally.

[0035] The ground-fixed slot plate unit 1 is cast and fixed, and its upper surface is slightly higher than the ground, or flush with the ground. The two side vertical plate units 2 are arranged on the left and right, and are connected to the ground-fixed slot plate unit 1 and the top plate box unit 3, ensuring that the rolling door has a stable rectangular frame structure. Moreover, the two vertical sides of the door body 13 are properly inserted into the side vertical plate unit 2 to ensure that the vertical side is not easily pried open or deformed.

[0036] Then there is the top plate box unit 3, which has the following functions: installing the motor 11, the rotating shaft 12 and the alarm 15, and accommodating the wound door body 13. In other words, the top plate box unit 3 has many internal structures and is not easy to be pried open.

[0037] Therefore, the anti-theft requirement is mainly on the engaging counterweight plate unit 5, which is engaged and locked with the ground fixed slot plate unit 1, and its active anti-theft effect is reflected in:

[0038] First, the gap between the engaging counterweight plate unit 5 and the ground fixing slot plate unit 1 is as small as possible so that common prying tools cannot be inserted;

[0039] Second, the gap between the two is vertical, not horizontal, so even if a prying tool has been inserted into the gap, it is difficult to pry the engaging counterweight plate unit 5 upwards, but it is easy to break the prying tool.

[0040] The passive anti-theft effect is reflected in that as long as the engaging counterweight plate unit 5 moves upward, the proximity switch 14 and the alarm 15 can be triggered, which has an alarm anti-theft effect.

[0041] It should be noted that the specific usage method of the proximity switch 14 can be any one of the following three methods.

[0042] First, when the owner opens and closes the rolling door normally, the proximity switch 14 and the alarm 15 also sound an alarm to remind people or pets near the rolling door to leave and avoid being lifted or pressed by the door body 13.

[0043] Secondly, when the owner opens and closes the rolling door normally, the proximity switch 14 and the alarm 15 are also triggered, but at this time the circuit on the motor 11 is connected, giving the alarm 15 an instruction so that the sound content is no longer an alarm sound, but a pre-set warm reminder message.

[0044] Third, when the owner opens and closes the rolling door normally, the proximity switch 14 and the alarm 15 are not triggered. At this time, a NOT switch is set between the proximity switch 14 circuit and the motor 11 circuit to ensure that the proximity switch 14 is disconnected when the motor 11 is running.

[0045] The above three usage methods can all be realized through existing simple control circuits.

[0046] The ground-fixed slot plate unit 1 includes a rectangular plate 101 and a rectangular slot 102 disposed on the upper surface of the rectangular plate 101 and used for inserting and engaging the engaging counterweight plate unit 5 .

[0047] In this embodiment, the rectangular plate 101 is made of ordinary high-strength steel, and its upper surface is flush with the ground, or slightly higher.

[0048] The ground-fixed slot plate unit 1 further includes a lock installation slot 103 arranged on the upper surface or side surface of the rectangular plate 101 .

[0049] In this embodiment, a simple lock groove or an inner concave ring is provided on the engaging counterweight plate unit 5 according to the existing common lock types to ensure that the lock can fix the engaging counterweight plate unit 5.

[0050] When the upper surface of the rectangular plate 101 is flush with the ground, the lock installation groove 103 can only be arranged on the upper surface thereof.

[0051] The ground-fixed slot plate unit 1 further comprises a pad 104 for filling the rectangular slot 102 when the rolling door is opened.

[0052] In this embodiment, the material of the pad 104 is also steel, and its thickness is equal to the depth of the rectangular groove 102, and its length and width are slightly smaller than the length and width of the rectangular groove 102. Its function is: when the rolling door is opened, it is used to fill the rectangular groove 102 to avoid a large amount of debris accumulation in the rectangular groove 102, thereby ensuring the smooth passage of passing vehicles there.

[0053] Among them, an inner concave pull ring for lifting is provided on the upper surface of the pad 104, which is used alternatively with the engaging counterweight plate unit 5.

[0054] In other words, when the rolling door is closed, the pad 104 is left idle in the room.

[0055] The side riser unit 2 includes a riser 201 disposed on the upper surface of the rectangular plate 101 and having a U-shaped cross-section, and a circular groove 202 disposed on the inner side of the riser 201 and used for mounting the proximity switch 14 .

[0056] In this embodiment, the openings of the two vertical plates 201 are arranged opposite to each other, and the circular groove 202 can be arranged on any one of the three inner sides of the vertical plates 201, because the end of the locking counterweight plate unit 5 is always inserted into the vertical plate 201, and as long as its end is flush with the proximity switch 14, it can be effectively triggered.

[0057] A single vertical plate 201 is provided with 3-5 proximity switches 14 arranged vertically.

[0058] In this embodiment, the above 3-5 pairs of proximity switches 14 can not only avoid the phenomenon of individual missed alarms after the door body 13 is pried open upward, but also ensure that the alarm can be successfully triggered even if the door body 13 is pried open on one side.

[0059] The top plate box unit 3 includes a single-end protruding box 301 which is arranged on the two vertical plates 201 and opens downward, two perforated plates 302 which are arranged in the single-end protruding box 301 and used to plug in the rotating shaft 12, and a protruding end horizontal plate 303 which is arranged in the single-end protruding box 301 and used to install the motor 11 and the alarm 15.

[0060] In this embodiment, the length of the single-ended protruding box 301 is greater than the distance between the two vertical plates 201, because the former is to accommodate the installation of the motor 11, which is also the origin of its name "single-ended protruding".

[0061] In addition, one of the long side panels of the single-end protruding box 301 is used to connect to the wall, and the two hole plates 302 are used to plug and fix the rotating shaft 12 and hang the door body 13.

[0062] Finally, the motor 11 is installed on the upper surface of the protruding end horizontal plate 303, and the alarm 15 is installed on the lower surface to ensure that the alarm sound can be directly transmitted.

[0063] The top plate box unit 3 further includes a protruding end cover orifice plate 304 arranged on the lower surface of the single-end protruding box 301 .

[0064] In this embodiment, the protruding end cover hole plate 304 is used to cover and protect the motor 11 and the alarm 15 to prevent them from being damaged or stolen.

[0065] The opening on the protruding end cover orifice plate 304 is used to transmit an alarm sound.

[0066] The orifice plate 302 is arranged on the limiting vertical rod 4 .

[0067] In this embodiment, the orifice plate 302 bears a large load, so its upper side and two side sides are fixedly connected to the single-end protruding box body 301, and its lower side is arranged on the limiting vertical rod 4. The limiting vertical rod 4 indirectly supports the weight of the door body 13 to ensure that the structure of the rolling door is more stable.

[0068] The engaging counterweight plate unit 5 includes a rectangular counterweight plate 501 arranged on the bottom edge of the door body 13 and used to be inserted into the rectangular slot 102 with the pad 104, and an end hole 502 arranged on the rectangular counterweight plate 501 and used to insert the limiting vertical rod 4.

[0069] In this embodiment, the door body 13 and the rectangular counterweight plate 501 are integrally formed, and the end surface of the rectangular counterweight plate 501 is located in the vertical groove of the vertical plate 201. The material of the rectangular counterweight plate 501 is also high-strength steel to ensure a certain hanging weight.

[0070] In addition, a ball bearing is provided in the end hole 502 to ensure that the resistance of the rectangular counterweight plate 501 is relatively small when it is raised and lowered on the limiting vertical rod 4. After all, the movement trend of the rectangular counterweight plate 501 is not completely straight up and down, and it is being diagonally pulled most of the time. Therefore, the drag reduction effect of the above-mentioned ball bearing is very necessary.

[0071] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
