Description

Technical Field

[0001] The utility model relates to the technical field of escape equipment, in particular to a lifting escape device. Background Art

[0002] While various types of emergency escape devices have been developed, such as descenders and rope escape devices, these devices can effectively help people safely evacuate from high-rise buildings or other dangerous environments in most cases. However, a significant technical limitation is that most escape device designs rely on two-handed operation, requiring the user to use both hands simultaneously to activate, control, or secure the device to ensure its stability and safety.

[0003] This design is reasonable under normal circumstances, but in specific emergency situations, such as when a single-handed person needs to hold an infant, elderly person, or other person unable to move independently, or for users with one-handed disabilities, existing escape devices are insufficient. The need for one-handed operation is particularly urgent in disaster escape scenarios, as it directly affects the scope and efficiency of personnel safety protection.

[0004] For this reason we provide a kind of lifting escape device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, not all 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.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figure 1 — Figure 8 The embodiment shown.

[0044] Since the existing escape device can be operated with both hands, if one-handed operation is required under special circumstances, the escape operation cannot be completed. Therefore, the present application provides an escape device to solve the above problem.

[0045] The present application discloses a lifting escape device, which includes a first column 100 and a second column 200, a first self-locking device 500, a second self-locking device 600, a first interlocking device 700, and a second interlocking device 800.

[0046] Specifically, the first column 100 and the second column 200 are independently arranged side by side, the first column 100 is installed with a first handbrake 300 on the top, the second column 200 is installed with a second handbrake 400 on the top, the first self-locking device 500 is fixedly installed on the first column 100, and the first self-locking device 500 is slidably connected to the second column 200, the first handbrake 300 is connected to the unlocking end of the first self-locking device 500, the second self-locking device 600 is fixedly installed on the second column 200, and the second self-locking device 600 is slidably connected to the first column 100, the second handbrake 400 is connected to the unlocking end of the second self-locking device 600, the first mutual unlocking device 700 includes a first transmission device 710 and a first driven device 720, the first transmission device 710 and the first driven device 720 are both fixed It is fixedly installed on the first column 100, the first transmission device 710 is connected to the first handbrake 300, the first driven device 720 is connected to the unlocking end of the first self-locking device 500, the second mutual unlocking device 800 includes a second transmission device 810 and a second driven device 820, the second transmission device 810 and the second driven device 820 are both fixedly installed on the second column 200, the second transmission device 810 is connected to the second handbrake 400, and the second driven device 820 is connected to the unlocking end of the second self-locking device 600, wherein the first handbrake 300 drives the second driven device 820 to unlock the second self-locking device 600 through the first transmission device 710, and the second handbrake 400 drives the first driven device 720 to unlock the first self-locking device 500 through the second transmission device 810.

[0047] See Figures 1 to 4 As shown, when unlocking is required to achieve downward descent, first, the first transmission device 710 and the second driven device 820 can be horizontally aligned, and correspondingly, the first driven device 720 and the second transmission device 810 can also be horizontally aligned. The purpose of doing this is to be able to transmit the force of the first transmission device 710 to the second driven device 820, and to transmit the force of the second transmission device 810 to the first driven device 720.

[0048] Specifically, when the first self-locking device 500 is unlocked by the first handbrake 300, the first handbrake 300 transmits force to the unlocking end of the first self-locking device 500 through the unlocking rope, and the escape rope is released by moving the unlocking end of the first self-locking device 500, that is, unlocking is achieved. In this process, the first handbrake 300 transmits force to the first self-locking device 500 and also transmits force to the first transmission device 710. The first transmission device 710 transmits force to the second driven device 820, and the second driven device 820 drives the unlocking end of the second self-locking device 600 to move, thereby unlocking the second self-locking device 600, and then achieving the first handbrake 30 0 When the first self-locking device 500 is unlocked, the second self-locking device 600 can also be unlocked; the simultaneous unlocking of the first self-locking device 500 and the second self-locking device 600 by the second handbrake 400 is similar to the above. Specifically, the second handbrake 400 transmits the unlocking force to the unlocking end of the second self-locking device 600 and also transmits it to the second transmission device 810, and then the second transmission device 810 transmits the power to the first driven device 720, and finally the first driven device 720 transmits the force to the unlocking end of the first self-locking device 500, so that the second handbrake 400 can unlock the second self-locking device 600 and the first self-locking device 500 at the same time.

[0049] In this embodiment, the first self-locking device 500 and the second self-locking device 600 can be unlocked at the same time by operating either the first handbrake 300 or the second handbrake 400, which expands the user range. In extreme cases, children, the elderly and other people can be held for emergency escape, and disabled people with only one arm can also use it.

[0050] In this embodiment, it should be noted that the first hand brake 300 and the second hand brake 400 can be understood as transmitting force to the first self-locking device 500 or the second self-locking device 600 through a rope that transmits power by holding it by hand. Specifically, the transmission method of the first hand brake 300 and the second hand brake 400 can refer to the existing bicycle brake assembly or other methods that can achieve power transmission, and are not specifically limited here.

[0051] Furthermore, the first handbrake 300 is connected to the first self-locking device 500 and the first transmission device 710 through a brake rope, the first driven device 720 is connected to the unlocking end of the first self-locking device 500 through a brake rope, the second handbrake 400 is connected to the second self-locking device 600 and the second transmission device 810 through a brake rope, and the second driven device 820 is connected to the unlocking end of the second self-locking device 600 through a brake rope, that is, when the first handbrake 300 unlocks the first self-locking device 500, it can transmit force to the first transmission device 710, and the first transmission device 710 transmits force to the second driven device 820 to unlock the second self-locking device 600. When the first handbrake 300 unlocks the second self-locking device 600, it transmits force to the second transmission device 810, and the second transmission device 810 transmits force to the first driven device 720 to unlock the first self-locking device 500.

[0052] Continue reading Figure 1 As shown, pedals 1000 are installed at the bottom of the first column 100 and the second column 200, and the pedals 1000 are used for people to stand. A waist belt 1100 is installed in the middle of the first column 100 or the second column 200, and the waist of the human body is fixed by the waist belt 1100 to prevent the human body from escaping from the device. Furthermore, the first column 100 and the second column 200 are respectively provided with a shell to prevent the limbs from entering the first column 100 or the second column 200 and causing injury.

[0053] The first transmission device 710 includes a first fixed shell 711 fixedly installed on the first column 100, a first installation cavity 712 is formed inside the first fixed shell 711, a first connecting rod driving structure 713 is arranged inside the first installation cavity 712, and the second driven device 820 includes a fourth fixed shell 821 fixedly installed, a fourth installation cavity 822 is formed inside the fourth fixed shell 821, and a second driven structure 823 is installed inside the fourth installation cavity 822. The driving end of the first connecting rod driving structure 713 drives the second driven structure 823 to unlock the second self-locking device 600.

[0054] The first connecting rod driving structure 713 includes a first sliding groove 7131 arranged in the first fixed shell 711 toward the fourth fixed shell 821, a first sliding rod 7132 is slidably installed in the first sliding groove 7131, and the first sliding rod 7132 is at least partially located in the first sliding groove 7131, a first spring 7133 is sleeved on the outer surface of the first sliding rod 7132, the first spring 7133 is used to reset the first sliding rod 7132, a first driving rod 7135 is rotatably installed in the first mounting cavity 712, and a first transmission rod 7134 is hingedly installed at the end of the first driving rod 7135 close to the first sliding rod 7132, and the end of the first transmission rod 7134 away from the first driving rod 7135 is hinged to the first sliding rod 7132.

[0055] The second driven structure 823 includes a fourth slide groove 8231 opened in the fourth fixed shell 821, and a third driven rod 8232 is slidably installed in the fourth slide groove 8231. The outer surface of the third driven rod 8232 is sleeved with a fourth spring 8233. The fourth spring 8233 is used to reset the third driven rod 8232. A second driven frame 8234 is rotatably installed in the fourth fixed shell 821, and the end of the third driven rod 8232 away from the first fixed shell 711 abuts against the driving end of the second driven frame 8234.

[0056] See Figure 4 As shown, when it is necessary to unlock the first self-locking device 500 and the second self-locking device 600 at the same time through the first handbrake 300, the first handbrake 300 can be first grasped to transmit force to the unlocking end of the first self-locking device 500. At this time, the force will also be transmitted to the position of the first driving rod 7135 and drive the first driving rod 7135 to move upward. When one end of the first driving rod 7135 moves upward, the other end will move downward. At this time, the force will be transmitted to the first sliding rod 7132 through the first transmission rod 7134 as a transmission member, thereby The first slide bar 7132 overcomes the elastic force of the first spring 7133 and drives the third follower bar 8232 to move to the right and enter the fourth slide groove 8231. The first slide bar 7132 contacts the third follower bar 8232 to move the third follower bar 8232 to the right, thereby driving the second follower frame 8234 to rotate, so that the end of the second follower frame 8234 away from the third follower bar 8232 moves upward, and then the second follower frame 8234 drives the unlocking end of the second self-locking device 600 to move, thereby unlocking the second self-locking device 600.

[0057] In this embodiment, the end of the second driven frame 8234 is connected to the unlocking end of the second self-locking device 600 through a brake rope. When the second driven frame 8234 rotates, the second self-locking device 600 can be unlocked through the brake rope.

[0058] In one embodiment, the first spring 7133 is between the step surface of the first slide bar 7132 and the inner wall of the first transmission device 710, so that when unlocking is required, the elastic force of the first spring 7133 can drive the first slide bar 7132 to return to its original position to achieve reset.

[0059] Furthermore, the fourth spring 8233 is located between the step surface of the third driven rod 8232 and the step surface inside the fourth sliding groove 8231. After unlocking is completed, the fourth spring 8233 drives the third driven rod 8232 to return to its initial position.

[0060] The second transmission device 810 includes a third fixed shell 811 fixedly installed on the second column 200, a third installation cavity 812 is formed inside the third fixed shell 811, and a second connecting rod driving structure 813 is arranged inside the third installation cavity 812; the first driven device 720 includes a second fixed shell 721 fixedly installed on the first column 100, a second installation cavity 722 is formed inside the second fixed shell 721, and a first driven structure 723 is installed inside the second installation cavity 722. The driving end of the second connecting rod driving structure 813 drives the first driven structure 723 to unlock the first self-locking device 500.

[0061] The second connecting rod driving structure 813 includes a third sliding groove 8131 arranged in the third fixed shell 811 toward the second fixed shell 721, and a second sliding rod 8132 is slidably installed in the third sliding groove 8131, and the second sliding rod 8132 is at least partially located in the third sliding groove 8131, and a third spring 8133 is sleeved on the outer surface of the second sliding rod 8132, and the third spring 8133 is used to reset the second sliding rod 8132, and a second driving rod 8135 is rotatably installed in the third installation cavity 812, and the second driving rod 8135 is hingedly installed with a second transmission rod 8134 at the end near the second sliding rod 8132, and the second transmission rod 8134 is hinged to the second sliding rod 8132 at the end away from the second driving rod 8135.

[0062] The first driven structure 723 includes a second slide groove 7231 opened in the second fixed shell 721, and a first driven rod 7232 is slidably installed in the second slide groove 7231. A second spring 7233 is sleeved on the outer surface of the first driven rod 7232. The second spring 7233 is used to reset the first driven rod 7232. A first driven frame 7234 is rotatably installed in the second fixed shell 721, and the end of the first driven rod 7232 away from the second transmission device 810 abuts against the driving end of the first driven frame 7234.

[0063] See Figure 4 As shown, when it is necessary to unlock the second self-locking device 600 and the first self-locking device 500 at the same time through the second handbrake 400, the second handbrake 400 can be held by hand to transmit power to the second self-locking device 600 and the second driving rod 8135 through the brake rope (not shown in the figure). During the unlocking process of the second self-locking device 600, the second driving rod 8135 is driven upward by the brake rope, and the other end moves downward. The second transmission rod 8134 drives the second sliding rod 8132 to overcome the elastic force of the third spring 8133 and move toward the first driven rod 7232. The second sliding rod 8132 enters the second sliding groove 7231 and abuts against the first driven rod 7232, driving the first driven rod 7232 to unlock. The driven rod 7232 abuts against and drives the first driven frame 7234 to rotate. The principle of the first driven frame 7234 is that the end of the first driven rod 7232 moves downward. Since the unlocking end of the first self-locking device 500 can only be unlocked by pointing upward, a pulley (not shown in the figure) can be set at the position of the first self-locking device 500 to change the direction of the force of the first driven frame 7234. The first driven frame 7234 drives the unlocking end of the first self-locking device 500 to move upward through the brake rope passing around the pulley, thereby unlocking the first self-locking device 500, and then realizing that the second handbrake 400 can unlock the first self-locking device 500 while unlocking the second self-locking device 600.

[0064] Continue reading Figure 4 As shown, the second spring 7233 is located between the step surface of the first driven rod 7232 and the step surface of the second slide groove 7231. When unlocking is not required, the second spring 7233 drives the first driven structure 723 to return to its initial position. Similarly, the third spring 8133 is located between the step surface of the second slide rod 8132 and the inner wall of the third mounting cavity 812. When unlocking is not required, the third spring 8133 drives the second slide rod 8132 to return to its initial position to achieve reset.

[0065] It should be noted that the function of mutual unlocking can be achieved only when the first driven device 720 and the second transmission device 810 are in the same horizontal plane, and the first transmission device 710 and the second driven device 820 are in the same horizontal plane, that is, the first driven rod 7232 and the second sliding rod 8132 are in the same horizontal plane, and the first sliding rod 7132 and the third driven rod 8232 are in the same horizontal plane.

[0066] The first self-locking device 500 includes a first mounting shell 510, in which a fixed structure 520 and a sliding guide structure 540 are installed. A fixed clamping wheel 530 is installed on the fixed structure 520, and a dynamic clamping wheel 550 is installed on the sliding guide structure 540. An unlocking rod 560 is rotatably installed in the first mounting shell 510, and the unlocking rod 560 is subjected to force to drive the dynamic clamping wheel 550 away from the fixed clamping wheel 530.

[0067] The fixed structure 520 includes a first mounting plate 521 fixedly installed in the first mounting shell 510, and the first mounting plate 521 is provided with a mounting groove 522 on the side facing the sliding guide structure 540. The fixed clamping wheel 530 is installed in each of the mounting grooves 522, and a first connecting plate 523 is installed between the same side ends of the fixed clamping wheel 530.

[0068] The sliding guide structure 540 includes a second mounting plate 541 fixedly installed in the first mounting shell 510, and a sliding groove 542 is opened on the side of the second mounting plate 541 facing the fixed structure 520, and the sliding groove 542 gradually increases in width from top to bottom. The dynamic clamping wheel 550 is arranged in each of the sliding grooves 542, and a second connecting plate 543 is installed between the ends of the same side surfaces of the dynamic clamping wheel 550. A connecting rod 544 is fixedly installed between the two second connecting plates 543, and the driving end of the unlocking rod 560 is connected to the connecting rod 544. The end of the unlocking rod 560 is subjected to force and transmits power through the connecting rod 544 and the second connecting plate 543 to drive the dynamic clamping wheel 550 to move in the sliding groove 542 away from the fixed clamping wheel 530.

[0069] In this embodiment, the first mounting shell 510 includes a first shell 511 and a second shell 512, the first shell 511 and the second shell 512 are hingedly connected, and the opening can be opened by the disassembly structure 900. Similarly, the second self-locking device 600 includes a second mounting shell 610, wherein the second mounting shell 610 includes a third shell 611 and a fourth shell 612, the third shell 611 and the fourth shell 612 are hingedly connected, and the opening can also be opened by the disassembly structure 900. Specifically, the internal structure of the first self-locking device 500 is the same as that of the second self-locking device 600, that is, the structure and method for achieving self-locking are the same. Here, only the internal structure of the first self-locking device 500 is elaborated in detail. Those skilled in the art can know the working principle of the second self-locking device 600 through the structural principle of the first self-locking device 500.

[0070] See Figure 5As shown, a semicircle is provided on the top and bottom of the first shell 511 and the top and bottom of the second shell 512, that is, a circular hole is provided on the top and bottom of the first mounting shell 510 respectively, through which the escape rope can enter between the fixed clamping wheel 530 and the dynamic clamping wheel 550 to achieve clamping and self-locking, and in order to prevent the escape rope from rubbing against the side wall of the circular hole, a guide block 570 can be provided at the circular hole to guide the escape rope through the guide block 570. The escape rope can be a steel wire rope or a rope-like product such as a nylon rope.

[0071] See Figure 5 As shown, the present application mainly realizes the clamping or loosening of the escape rope between the fixed clamping wheel 530 and the dynamic clamping wheel 550 by moving the fixed clamping wheel 530 and the dynamic clamping wheel 550 closer or farther away from each other to clamp the escape rope, which is in a self-locking state; when the fixed clamping wheel 530 and the dynamic clamping wheel 550 move away from each other to relax the escape rope, it is in an unlocked state, that is, under the action of gravity, the escape rope can be lowered down to escape.

[0072] Specifically, in this embodiment, the fixed clamping wheel 530 is rotatably mounted on the fixed structure 520, and the dynamic clamping wheel 550 is rotatably mounted on the sliding guide structure 540. The unlocking rod 560 is subjected to force to drive the dynamic clamping wheel 550 in the sliding guide structure 540 to move downward, thereby forcing the distance between the fixed clamping wheel 530 and the dynamic clamping wheel 550 to increase, thereby achieving unlocking.

[0073] Furthermore, there are two first mounting plates 521 and both are fixedly mounted inside the first housing 511. Two mounting slots 522 are provided on each first mounting plate 521. The fixed clamping wheels 530 are mounted in the two mounting slots 522 at the same level. Figure 5 As shown, a fixed clamping wheel 530 is installed in the installation groove 522. Since there are two fixed clamping wheels 530, in order to maintain the stability of the fixed clamping wheels 530, the two ends of the two fixed clamping wheels 530 are connected by a first connecting plate 523.

[0074] In this embodiment, the sliding guide structure 540 also has two second mounting plates 541, and the two second mounting plates 541 are fixedly mounted on the second shell 512. Two sliding grooves 542 are provided on the side of the second mounting plate 541 facing the first mounting plate 521, that is, there are two sets of upper and lower sliding grooves 542, and the width of the sliding grooves 542 increases from top to bottom. A dynamic clamping wheel 550 is provided in the two sliding grooves 542 on the same horizontal plane. At this time, there are two dynamic clamping wheels 550, and the two ends of the two dynamic clamping wheels 550 are connected by a second connecting plate 543. In order to enable the dynamic clamping wheel 550 to move downward, a connecting plate 543 is installed on the second connecting plate 543. The connecting rod 544 is connected to the unlocking rod 560. When the end of the unlocking rod 560 away from the connecting rod 544 is lifted upward, the end of the unlocking rod 560 connected to the connecting rod 544 will move downward, and will simultaneously drive the second connecting plate 543 and the dynamic clamping wheel 550 to move downward. During the downward movement, the dynamic clamping wheel 550 will be close to the side wall of the sliding groove 542. Since the width of the sliding groove 542 gradually increases downward, the dynamic clamping wheel 550 will gradually move away from the fixed clamping wheel 530 as it moves downward following the second connecting plate 543, thereby reducing the clamping force on the escape rope between the fixed clamping wheel 530 and the dynamic clamping wheel 550, thereby achieving unlocking.

[0075] It should be noted that the first self-locking device 500 is automatically in a locked state under the action of gravity. Specifically, if it is not unlocked by the first handbrake 300 and the second handbrake 400, the entire device will have a downward trend. During the descent, the escape rope contacts the outer surface of the dynamic clamping wheel 550, giving the dynamic clamping wheel 550 an upward force. Since the upper width of the sliding groove 542 is narrow, the dynamic clamping wheel 550 will be driven toward the fixed clamping wheel 530. As the distance between the fixed clamping wheel 530 and the dynamic clamping wheel 550 becomes smaller, the escape rope between the two will be clamped to complete the locking.

[0076] Since the structures of the first self-locking device 500 and the second self-locking device 600 are the same, the detailed working process of the second self-locking device 600 will not be described here.

[0077] See Figure 6As shown, the second shell 512 in the first mounting shell 510 is fixedly connected to the first column 100 by connecting bolts, and a ball plunger 580 is provided on the first shell 511. Correspondingly, a corresponding positioning hole is provided at the position of the second column 200. When the ball plunger 580 is located at the position of the positioning hole, it can be determined that the second transmission device 810 corresponds to the first driven device 720 and the first transmission device 710 corresponds to the second driven device 820. At this time, the first self-locking device 500 and the second self-locking device 600 can be unlocked simultaneously by the first handbrake 300 or the second handbrake 400.

[0078] The present application further includes a disassembly structure 900 , and the second self-locking device 600 includes a second mounting shell 610 . The disassembly structure 900 is used to open the first mounting shell 510 and the second mounting shell 610 .

[0079] The disassembly structure 900 includes a first fixing block 910 and a first clamping block 920 provided at the opening of the first mounting shell 510, and the first fixing block 910 is clamped with the first clamping block 920; a second fixing block 950 and a second clamping block 960 are provided at the opening of the second mounting shell 610, and the second fixing block 950 is clamped with the second clamping block 960.

[0081] A second connecting column 970 is mounted on the second clamping block 960 . A second return spring 980 is sleeved on the second connecting column 970 . The second return spring 980 is located between the inner wall of the second mounting shell 610 and the second clamping block 960 .

[0082] A fixing plate 990 is fixedly mounted on the first column 100 or the second column 200 , and an unlocking knob 9010 is rotatably mounted on the fixing plate 990 . The unlocking knob 9010 is connected to the first connecting column 930 and the second connecting column 970 respectively through a transmission rope.

[0083] See Figure 7 and Figure 8 As shown, in order to enable the first mounting shell 510 and the second mounting shell 610 to be opened and the escape rope to be installed between the fixed clamping wheel 530 and the dynamic clamping wheel 550, it is necessary to open the first mounting shell 510 and the second mounting shell 610 to complete the installation. For this purpose, it is applied to quickly open the first mounting shell 510 and the second mounting shell 610 by disassembling the structure 900.

[0084] Continue reading Figure 7 and Figure 8 As shown, the first fixing block 910 is fixedly installed on the first shell 511, the first clamping block 920 can be slidably installed on the second shell 512, the second clamping block 960 is slidably installed on the third shell 611, and the second fixing block 950 is fixedly installed on the fourth shell 612. Specifically, a card slot is provided on the first fixing block 910, and a clamping portion is provided on the first clamping block 920. The clamping portion of the first clamping block 920 can be clamped into the card slot on the first fixing block 910 to complete the closure of the opening of the first installation shell 510. Correspondingly, a card slot is also provided on the second fixing block 950, and a clamping portion is also provided on the second clamping block 960. The second clamping block 960 can be clamped into the card slot on the second fixing block 950 to complete the closure of the opening of the second installation shell 610.

[0085] In this embodiment, the elastic force of the first return spring 940 keeps the clamping portion of the first clamping block 920 in the clamping slot of the first fixed block 910 and is in a clamping state. The first connecting column 930 connected to the first clamping block 920 can be connected to the unlocking knob 9010 through a pull rope. Correspondingly, the elastic force of the second return spring 980 keeps the clamping portion of the second clamping block 960 in the clamping slot of the second fixed block 950 and is in a clamping state. The second connecting column 970 connected to the second clamping block 960 can also be connected to the unlocking knob 9010 through a pull rope.

[0086] Specifically, when it is necessary to open the first mounting shell 510 and the second mounting shell 610, it is only necessary to rotate the unlocking knob 9010 to drive the first connecting column 930 and the second connecting column 970 to move through the pull rope, thereby overcoming the elastic force of the first return spring 940 and causing the clamping portion of the first clamping block 920 to disengage from the clamping slot of the first fixed block 910. At this time, the first shell 511 and the second shell 512 are in a separated state, so that the two can be opened at this time. Correspondingly, the second connecting column 970 connected to the second clamping block 960 is pulled through the pull rope to overcome the elastic force of the second return spring 980 and cause the clamping portion of the second clamping block 960 to disengage from the clamping slot of the second fixed block 950. At this time, the third shell 611 and the fourth shell 612 are in a separated state, so that the two can be opened.

[0087] Continue reading Figure 8As shown, in another embodiment, the fixing plate 990 and the unlocking knob 9010 are both divided into two, which can be recorded as a first plate body, a second plate body, a first knob and a second knob. Accordingly, the first knob is rotatably mounted on the first plate body, the second knob is mounted on the second plate body, the first plate body is mounted on the first column 100, and the second plate body is mounted on the second column 200. The first knob on the first plate body is connected to the first connecting column 930 through a pull rope, and the second knob on the second plate body is connected to the second connecting column 970 through a pull rope; that is, when it is necessary to open the first mounting shell 510 or the second mounting shell 610, it is only necessary to rotate the first knob and the second knob respectively to open them.
