[0034] Please refer to Figures 1 to 6The present embodiment discloses a pressure plate locking device, including a first bracket 100, a second bracket 200, a first mounting mechanism 300, a second mounting mechanism 400, a first limiting member 500 and at least one pressure plate locking cover plate 600, wherein the second bracket 200 is arranged on a first side of the first bracket 100, the first mounting mechanism 300 is connected to a first end of the first bracket 100 and a first end of the second bracket 200, the first mounting mechanism 300 is movably provided with a first limiting locking pin 310 and a first locking hole 301, the first limiting locking pin 310 is provided with a second locking hole 311 adapted to the first locking hole 301, and the second mounting mechanism 400 is provided with a first limiting locking pin 310 and a second locking hole 311 adapted to the first locking hole 301. The mechanism 400 is connected to the second end of the first bracket 100 and the second end of the second bracket 200, the first end of the first limiting member 500 is movably connected to the first mounting mechanism 300, the second end of the first limiting member 500 is movably connected to the second mounting mechanism 400, the first limiting member 500 is provided with a first limiting portion 501, the first end of the pressure plate locking cover 600 is rotatably installed on the second bracket 200, and the first side of the pressure plate locking cover 600 is adjacent to the first bracket 100, the pressure plate locking cover 600 is movably provided with a second limiting lock pin 610, and the second limiting lock pin 610 is provided with a third locking hole 611. Among them, the first limit member 500 has a first working position and a second working position that can be switched. When the first limit member 500 is in the first working position, the first limit member 500 is located at the second end of the pressure plate locking cover 600, and the second limit lock pin 610 can be connected with the first limit part 501 in a limiting manner; when the first limit member 500 is in the second working position, the first limit member 500 is located on the second side of the pressure plate locking cover 600, and the first limit lock pin 310 can be connected with the first limit member 500 in a limiting manner, the first end and the second end of the pressure plate locking cover 600 are arranged opposite to each other, and the first side and the second side of the pressure plate locking cover 600 are arranged opposite to each other.

[0035] When using, please refer to Fig.12, the first mounting mechanism 300 and the second mounting mechanism 400 are mounted on the secondary equipment, so as to fix the first bracket 100, the second bracket 200 and the first stopper 500, wherein the secondary equipment is provided with a protective pressure plate 040, the second bracket 200 and the first stopper 500 are both located on the first side of the first bracket 100, the first bracket 100 is provided with an avoidance hole 101, and the first bracket 100 is sleeved on the peripheral side of the protective pressure plate 040 through the avoidance hole 101. According to the requirements of actual applications, the number of the pressure plate locking cover plates 600 can be one or more, and when the number of the pressure plate locking cover plates 600 is multiple, multiple pressure plate locking cover plates 600 are installed side by side on the second bracket 200. Since the pressure plate locking cover plate 600 is rotatably connected to the second bracket 200, the pressure plate locking cover plate 600 can rotate around the second bracket 200 in a direction away from or close to the first bracket 100, thereby opening the pressure plate locking cover plate 600 to expose the protective pressure plate 040, and then completing the insertion and withdrawal of the protective pressure plate 040. When performing maintenance, it is necessary to lock the pressure plate locking cover plate 600 with a padlock to avoid misoperation during the maintenance process, which is conducive to improving the safety of maintenance. In actual applications, the number of pressure plate locking cover plates 600 is usually multiple. In the related art, the individual locking of a single protective pressure plate 040 and the overall locking of multiple protective pressure plates 040 are realized by separate two mechanisms, which is inconvenient to use. However, this embodiment can realize both the individual locking of a single protective pressure plate 040 and the overall locking of multiple protective pressure plates 040.

[0036] Specifically, when the first limiting member 500 is in the first working position (eg Figures 1 to 4 As shown in the figure, the first end of the pressure plate locking cover 600 is rotatably connected to the second bracket 200, and the first limiting member 500 is located at the second end of the pressure plate locking cover 600. The pressure plate locking cover 600 can rotate around the second bracket 200. When it is necessary to lock a certain pressure plate locking cover 600 individually, the second limiting lock pin 610 on the pressure plate locking cover 600 is pushed to limit the second limiting lock pin 610 to the first limiting portion 501 on the first limiting member 500, and the first padlock 010 is inserted into the third lock hole 611, so as to prevent the second limiting lock pin 610 from being separated from the first limiting portion 501, thereby limiting the rotation of the pressure plate locking cover 600 around the second bracket 200.

[0037] When the first limiting member 500 is in the second working position (eg Figure 5As shown in FIG. 1 , the first position-limiting member 500 is located at the second side of the pressing plate locking cover plate 600, and the first position-limiting locking pin 310 can be connected with the first position-limiting member 500. At this time, the first locking hole 301 and the second locking hole 311 are aligned, and the second padlock 020 is inserted into the first locking hole 301 and the second locking hole 311, thereby locking the first position-limiting locking pin 310, thereby preventing the first position-limiting member 500 from switching to the first working position. In short, when the first position-limiting member 500 is in the second working position, the pressing plate locking cover plate 600 is located in the area between the first position-limiting member 500 and the first bracket 100, so that the pressing plate locking cover plate 600 cannot rotate around the second bracket 200. It should be noted that when the first limit member 500 is in the second working position, multiple pressure plate locking cover plates 600 arranged side by side can be locked without the need to individually lock each pressure plate locking cover plate 600, and the first limit member 500 of this embodiment can be switched between the first working position and the second working position, and there is no need to disassemble and assemble when switching between individual locking and overall locking, which is convenient to use.

[0038] In some application examples, the first end of the first stopper 500 is rotatably connected to the first mounting mechanism 300, and the second end of the first stopper 500 is rotatably connected to the second mounting mechanism 400, and the first stopper 500 can be rotatably switched between the first working position and the second working position. For example, the first end of the first stopper 500 is provided with a first connecting portion, and the first connecting portion is provided with a first mounting hole, and the second end of the first stopper 500 is provided with a second connecting portion, and the second connecting portion is provided with a second mounting hole, and fasteners such as screws, bolts or pins are inserted through the first mounting hole and the second mounting hole, so as to realize the rotatable connection between the first stopper 500 and the first mounting structure and the second mounting mechanism 400. When in the first working position, the first limit member 500 is located at the second end of the pressure plate locking cover 600 and has no intersection with the rotation path of the pressure plate locking cover 600; when the first limit member 500 rotates around the virtual rotation axis where the first mounting hole and the second mounting hole are located at a preset angle such as 60°, 90° or 120°, the first limit member 500 can switch from the first working position to the second working position and is located on the rotation path of the pressure plate locking cover 600, thereby limiting the rotation of the pressure plate locking cover 600.

[0039] In other application examples, a first guide portion (not shown) is provided at the first end of the first limiting member 500, and is movably connected to the first mounting mechanism 300 through the first guide portion. A second guide portion (not shown) is provided at the second end of the first limiting member 500, and is movably connected to the second mounting mechanism 400 through the second guide portion. The first limiting member 500 can be switched translationally between the first working position and the second working position. For example, a first connecting portion is provided at the first end of the first limiting member 500, and a first waist hole used as a first guide portion is provided on the first connecting portion; a second connecting portion is provided at the first end of the first limiting member 500, and a second waist hole used as a second guide portion is provided on the second connecting portion. Accordingly, a first guide column (not shown) corresponding to the first waist hole is provided on the first mounting mechanism 300, and the first guide column is installed in the first waist hole; a second guide column (not shown) corresponding to the second waist hole is provided on the second mounting mechanism 400, and the second guide column is installed in the second waist hole. In this way, through the cooperation of the first guide column and the first waist hole, the second guide column and the second waist hole, the first limiting member 500 can move along the limited direction of the first waist hole and the second waist hole. When in the first working position, the first stopper 500 is located at the second end of the pressing plate locking cover plate 600 and has no intersection with the rotation path of the pressing plate locking cover plate 600; when the first stopper 500 is translated along the up and down directions defined by the first waist hole and the second waist hole, the first stopper 500 can be switched from the first working position to the second working position and is located on the rotation path of the pressing plate locking cover plate 600, thereby limiting the rotation of the pressing plate locking cover plate 600. For another example, the first guide portion is a guide column (not shown) provided on the first stopper, and correspondingly, a guide groove (not shown) adapted to the guide column is provided on the first mounting mechanism 300, and the guide column is installed in the guide groove and can move along the guide groove.

[0040] In practical applications, the first limiting member 500 can adopt structures such as plates, rods or blocks. Exemplarily, the first limiting member 500 adopts a limiting plate, which can be processed by conventional processes such as sheet metal and bending, which is convenient to process and is conducive to reducing processing costs. The limiting plate is provided with at least one of a hole and a groove used as the first limiting portion 501. Specifically, the limiting plate can be processed by drilling to obtain a limiting hole corresponding to the second limiting locking pin 610, and the limiting hole can be a through hole, a blind hole or a stepped hole, etc., and according to the shape, the limiting hole can be a round hole, a semicircular hole, an elliptical hole or a waist hole, etc. The limiting plate can also be processed by drilling to obtain a limiting groove corresponding to the second limiting locking pin 610, and the limiting groove can be a through groove, a blind groove or a stepped groove, etc., and according to the shape, the limiting groove can be a strip groove or a notched groove, etc. When a single locking is performed, the second limiting locking pin 610 is penetrated or inserted into the limiting hole or the limiting groove, so as to realize the rotation limit of the pressing plate locking cover plate 600.

[0041] Similarly, please refer to Figure 7, the first limiting member 500 is provided with a second limiting portion 502 adapted to the first limiting locking pin 310. The second limiting portion 502 may be a hole or a groove. For example, the first limiting member 500 is provided with a first connecting portion, and the first connecting portion is provided with a first limiting hole and a second limiting hole used as the second limiting portion 502. When the first limiting member 500 is in the first working position, the first limiting locking pin 310 can be inserted or inserted into the first limiting hole, thereby limiting the first limiting member 500 from switching the working position; similarly, when the first limiting member 500 is in the second working position, the first limiting locking pin 310 can be inserted or inserted into the second limiting hole, thereby limiting the first limiting member 500 from switching the working position. It should be conceivable that the first limiting hole and the second limiting hole can be replaced by a first limiting groove and a second limiting groove, and both the first limiting groove and the second limiting groove can be strip grooves or notched grooves. Of course, in some application examples, only the first limiting hole may be set on the first limiting member 500. For example, when the first limiting member 500 is in the first working position, the first limiting lock pin 310 can be passed through or inserted into the first limiting hole, and when the first limiting member 500 is in the second working position, the first limiting lock pin 310 is located on the rotation or movement path of the first limiting member 500, thereby limiting the first limiting member 500 from switching the working position.

[0042] In actual applications, it is found that the space on the secondary equipment is limited. In the related art, after the protective pressure plate is locked, the padlock is usually suspended below the protective pressure plate or placed on one side of the protective pressure plate, which causes the padlock to not be laid flat, making the overall height higher after the padlock is hung. In view of the defects of the related art, this embodiment proposes a cover plate structure to reduce the overall height after the padlock is hung. Please refer to Figure 1 and Figure 8The cover plate structure proposed in this embodiment includes a cover plate body 601, a first mounting portion 602 and a rotating mounting portion 603. The cover plate body 601 has a first end and a second end opposite to each other. The rotating mounting portion 603 is arranged at the first end of the cover plate body 601. The cover plate body 601 can rotate around a virtual axis formed by the rotating mounting portion 603. The two opposite sides of the cover plate body 601 in the rotation direction are respectively a first side and a second side. A blocking wing 605 is arranged on the first side of the cover plate body 601. The first mounting portion 602 is arranged on the second side surface of the cover plate body 601. A third mounting hole 604 for mounting a second limiting lock pin 610 is arranged on the first mounting portion 602. The opening of the third mounting hole 604 faces the second end of the cover plate body 601. The second side surface of the cover plate body 601 and the area located around the first mounting portion 602 are used as a first padlock placement area. Since the lock beam 030 of the padlock is a semi-circular structure, when the padlock is hung, the lock beam 030 of the padlock can be mounted on the outside of the first mounting portion 602, so that most of the padlock can be located in the first padlock placement area, rather than being suspended below or on one side of the cover body 601, which is beneficial to reducing the overall height after the padlock is hung.

[0043] In some application examples, the rotating mounting portion 603 is a circular ring or a semicircular ring disposed at the first end of the cover body 601. In other application examples, the rotating mounting portion 603 includes a protrusion (not shown) disposed at the first end of the cover body 601, and a through hole or a semicircular hole is disposed on the protrusion. When in use, the rotating mounting portion 603 is mounted on a rotating shaft, such as the second bracket 200 shown in the figure, and the second bracket 200 is a straight rod.

[0044] For ease of processing, the first mounting portion 602 adopts a block structure or a plate structure. For example, the first mounting portion 602 is a mounting block, the third mounting hole 604 is set on the mounting block by drilling, and the mounting block is welded to the cover body 601; for another example, the first mounting portion 602 is a mounting plate, the mounting plate is processed into an L-shape, U-shape or square shape by sheet metal processing, the third mounting hole 604 is set on the mounting plate by drilling, and the mounting plate is welded to the cover body 601; for another example, the first mounting portion 602 and the cover body 601 are integrally formed by injection molding. Please refer to Figure 1 It should be noted that the first mounting portion 602 is located adjacent to the second end of the cover body 601, so that after the second limiting lock pin 610 is inserted into the third mounting hole 604, it can be connected to the first limiting member 500, and the padlock can be as close to the first limiting member 500 as possible to reduce the overall height after the padlock is hung. Fig.12 As shown, the distance d between the first mounting portion 602 and the second end of the cover body 601 is less than or equal to the radius r of the padlock beam 030 .

[0045] In some application examples, a third limiting portion (not shown) is provided inside the third mounting hole 604, a fourth limiting portion 612 is provided on the outer wall of the second limiting locking pin 610, the second limiting locking pin 610 is passed through the third mounting hole 604, and abuts against the first mounting portion 602 through an elastic reset member 620, and a third limiting member 630 is installed. The elastic reset member 620 is a spring, the first end of the elastic reset member 620 abuts against the third limiting portion, the second end of the elastic reset member 620 abuts against the fourth limiting portion 612, and the third limiting member 630 is used to limit the travel of the second limiting locking pin 610 to prevent the limiting locking pin from being separated from the third mounting hole 604. Specifically, the third mounting hole 604 is a stepped hole, the third limiting portion is a first annular flange arranged on the inner wall of the stepped hole, the fourth limiting portion 612 is a second annular flange arranged on the outer wall of the second limiting lock pin 610, and the third limiting member 630 adopts a nut, or the third limiting member 630 adopts a limiting block with an internal threaded hole, and accordingly, the end of the second limiting lock pin 610 is provided with a connecting thread. Under the elastic force of the elastic reset member 620, the second limiting lock pin 610 can extend out of the edge of the second end of the cover body 601, so as to be limitedly connected with the first limiting member 500. At this time, the third lock hole 611 arranged on the second limiting lock pin 610 is located in the area between the first mounting portion 602 and the second end of the cover body 601, so as to facilitate the padlock to be inserted into the third lock hole 611, so as to hang the padlock; or, under the elastic force of the elastic reset member 620, the second limiting lock pin 610 is located on the inner side of the edge of the second end of the cover body 601, so as to have no contact with the first limiting member 500. At this time, the third lock hole 611 arranged on the second limiting lock pin 610 is located in the first mounting portion 602. Pushing the second limiting lock pin 610 can make the third limiting hole located in the area between the first mounting portion 602 and the second end of the cover body 601, so as to facilitate the padlock to be inserted into the third lock hole 611, so as to hang the padlock.

[0046] Please refer to Figures 1 to 3 The pressure plate locking cover 600 mentioned above adopts the above-mentioned cover structure, that is, the second side surface of the pressure plate locking cover 600 is provided with a first mounting portion 602, and the second side surface of the pressure plate locking cover 600 and the peripheral side of the first mounting portion 602 are used as the first padlock placement area, the second limit lock pin 610 is movably penetrated through the first mounting portion 602, and the third lock hole 611 can be located in the area between the first mounting portion 602 and the second end of the pressure plate locking cover 600, so that most of the first padlock 010 can be located in the first padlock placement area, which is beneficial to the overall height after the first padlock 010 is hung.

[0047] Similarly, please refer to Figure 2 In order to reduce the overall height after the second padlock 020 is hung when the whole is locked, the first limit lock pin 310 is set at the corner of the first installation mechanism 300 (such as Fig.10 As shown in the figure, the surface where the first limiting lock pin 310 intersects with the first mounting mechanism 300 is the first surface of the first mounting mechanism 300, and an extension portion 320 is provided on the first mounting mechanism 300 and located on one side of the first limiting lock pin 310, the plane where the extension portion is located is perpendicular to the first surface of the first mounting mechanism 300, and the first lock hole 301 is provided on the extension portion 320. Among them, the extension part 320 can adopt a strip structure or a plate structure. For example, the extension part 320 is a strip welded on the first mounting mechanism 300, and a through hole used as the first lock hole 301 is provided on the strip. When the first limit lock pin 310 is passed through the first mounting mechanism 300 and is limitedly connected with the first limit member 500, the second lock hole 311 on the first limit lock pin 310 is aligned with the first lock hole 301, and the second padlock 020 can be passed through the first lock hole 301 and the second lock hole 311 to limit the movement of the first limit lock pin 310, thereby limiting the first limit member 500 from switching the working position, thereby achieving overall locking.

[0048] Please refer to Figures 1 to 3 , similar to the first mounting mechanism 300, the second mounting mechanism 400 is provided with a third lock pin 410 and a fourth lock hole 401, and the third lock pin 410 is provided with a fifth lock hole 411 adapted to the fourth lock hole 401. The third lock pin 410 is provided in the second mounting mechanism 400 and can be connected with the first position limiting member 500. When the third lock pin 410 is connected with the first position limiting member 500, the fourth lock hole 401 and the fifth lock hole 411 are aligned, and the second padlock 020 can be provided in the fourth lock hole 401 and the fifth lock hole 411, and finally the overall locking is realized. It should be noted that the third lock pin 410 can be used as a backup, and the second mounting mechanism 400 adopts the same structure as the first mounting mechanism 300.

[0049] Considering that the secondary equipment is usually a metal structure such as iron, stainless steel or iron alloy, the first mounting mechanism 300 and the second mounting mechanism 400 are both magnetic mounting mechanisms. Exemplarily, the first mounting mechanism 300 includes a shell and a magnetic component installed in the shell. The shell is provided with an operating knob for controlling the magnetic component. When the operating knob is rotated to the "ON" position, the magnetic component works to generate magnetic force. When the operating knob is rotated to the "OFF" position, the magnetic component stops working to eliminate the magnetic force. In this way, the first mounting mechanism 300 can be easily installed or disassembled, which is conducive to improving the convenience of use. It should be noted that the magnetic component can adopt an integrated module on the market. Of course, the magnetic component can also be improved according to the actual application environment, for example, to enhance or weaken the strength of the magnetic force.

[0050] In some application examples, the magnetic mounting mechanism can be improved, for example, please refer to Fig.11A mounting cavity (not shown) is provided in the shell of the first mounting mechanism 300, in which a steel ball 331, an elastic member 332 and a fourth limiting member 333 are installed. The fourth limiting member 333 fixes the steel ball 331 and the elastic member 332 in the mounting cavity. Correspondingly, the first limiting lock pin 310 is located on the opening side of the mounting cavity, and the first limiting lock pin 310 is provided with a limiting recess 312. The steel ball 331 abuts against the limiting recess 312 of the first limiting lock pin 310 under the action of the elastic member 332, thereby limiting the first limiting lock pin 310.

[0051] For example, see Figure 3 and Figure 6 , a mounting groove 340 is provided at the bottom of the housing of the first mounting mechanism 300, a fourth mounting hole 201 is provided at the first end of the second bracket 200, and the second bracket 200 is mounted in the mounting groove 340 through the fourth mounting hole 201 and a fastener such as a screw or bolt. In this way, when a padlock is hung but the padlock key is lost, the second bracket 200 can be easily disassembled, thereby disassembling and replacing the pressure plate locking cover 600, avoiding the safety risk caused by cutting the padlock on site.

[0052] Please refer to Fig.12 When in use, the platen locking device is installed on the secondary equipment, the first bracket 100 is sleeved on the outer side of the protective platen 040 through the avoidance hole 101, and the platen locking cover 600 can be covered on the protective platen 040. When the protective platen 040 is locked individually, the platen locking cover 600 is covered on the corresponding protective platen 040, and the retaining wing 605 of the platen locking cover 600 can limit the lock 041 of the protective platen 040 to prevent the protective platen 040 from resetting, so as to improve the safety of operation. When multiple protective platens 040 are locked as a whole, the first limiting member 500 rotates a preset angle so that the first limiting member 500 is located on the second side of the protective platen 040, thereby limiting the rotation of the protective platen 040, and then realizing the overall locking of multiple protective platens 040. The first limiting member 500 of the present embodiment can be switched between a first working position and a second working position. When the first limiting member 500 is in the first working position, the pressure plate locking cover 600 can be individually limited in cooperation with the second limiting lock pin 610. When the first limiting member 500 is in the second working position, all the pressure plate locking cover plates 600 can be limited as a whole. In this way, the pressure plate 040 can be shielded and protected by the pressure plate locking cover plate 600, so that the individual locking and overall locking of the protective pressure plate 040 can be achieved.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
