Description

Technical Field

[0001] The present invention belongs to the field of defense / the technical field of display and control equipment applications in harsh environments, and in particular relates to a vibration-resistant, easy-to-store, adjustable damping paper rack mechanism suitable for message display and control equipment. Background Art

[0002] Display and control equipment used in the defense field, especially display and control equipment used in the message field, is mostly used to enter external paper message information into the display and control equipment and distribute instructions.

[0003] Defense / harsh environment message display and control equipment often requires a keyboard, mouse, status display, KVM, alarm, and other functional modules on the control console. The space is extremely limited, and there is no space on the plane the size of a paper document. In addition, this type of display and control equipment is often used in places such as ships, vehicles, and aircraft that are subject to vibration and shock.

[0004] The message display and control device is responsible for inputting incoming paper messages. Due to application limitations, scanning, photographing, and other methods are not possible, requiring only typing of the relevant instructions on the message. Message operators may hold the document in their left hand while typing with their right hand, severely impacting text input efficiency. Alternatively, they may place random documents on the table, where vibrations from the message display and control device can cause the document to fall off the table and obstruct other functional modules, further reducing input efficiency.

[0005] In response to the above technical problems, a vibration-resistant and easy-to-store adjustable damping paper rack mechanism suitable for message display and control equipment is proposed. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a vibration-resistant, easy-to-store adjustable damping paper rack mechanism suitable for message display and control equipment. Through a spring locking mechanism, a spring top ball positioning locking mechanism and magnetic attraction, the damping paper rack on the control table of the message display and control equipment is prevented from jumping and swinging in a vibration environment, and the message entry function can be carried out in a vibration environment.

[0007] The present invention solves the technical problem by the following technical solutions:

[0008] A vibration-resistant and easy-to-store adjustable damping paper holder mechanism suitable for message display and control equipment, wherein a groove is provided on the control table of the message display and control equipment, and a spring locking mechanism, a spring top ball positioning locking mechanism, a damping paper holder and a magnetic attraction are installed in the groove;

[0009] The spring locking mechanism includes a hook, a long compression spring, a button and a short compression spring;

[0010] The spring top ball positioning and locking mechanism includes a top ball fixing frame;

[0011] The damping paper rack includes a paper rack main rod, and foldable left and right arms are respectively installed at the left and right ends of the top of the paper rack main rod. The bottom of the paper rack main rod is installed at one end of the groove. The top of the paper rack main rod is clamped in the groove through a hook located at the other end of the groove. The paper rack main rod is ejected from the groove by a button located at the front end of the hook, a long compression spring and a short spring located in the middle of the groove.

[0012] A top ball fixing frame is installed at the front end of the bottom of the paper rack main rod installed at one end of the groove, and spring top balls are installed at the left and right ends of the top ball fixing frame. The spring top balls are clamped in the spring top ball grooves at the left and right ends of the bottom of the paper rack main rod to lock the paper rack main rod;

[0013] The magnetic attraction installed on the main rod of the paper rack is removed and placed on the left and right arms at the left and right ends of the top of the paper rack main rod, respectively, to adsorb paper documents on the left and right arms at the left and right ends of the top of the paper rack main rod.

[0014] Furthermore, the left support arm and the right support arm are respectively installed on the left and right ends of the top of the paper rack main rod through a fixed shaft welded with a pressure plate, a damping plate and a damping sleeve, and are screwed on the paper rack main rod through the pressure plate.

[0015] Furthermore, the main rod of the paper rack is provided with a chamfered hook groove, a magnetic groove and a short spring groove from top to bottom; the chamfered hook groove is clamped with a hook; the magnetic groove is installed with a magnet; and the short spring groove is installed with a short spring.

[0016] Furthermore, the bottom of the paper rack main rod is installed at one end of the groove through a paper rack shaft.

[0017] Furthermore, the hook is installed at the other end of the groove through a shaft.

[0018] Furthermore, the long compression spring is screwed onto the front end of the hook through a spring sleeve.

[0019] Furthermore, after the left support arm and the right support arm at the left and right ends of the top of the main rod of the paper holder are folded, the folding damping paper holder forms a strip structure and is placed in a groove opened on the control table of the message display and control device.

[0020] Furthermore, the spring top ball grooves located at the left and right ends of the bottom of the paper rack main rod are hemispherical spring top ball grooves.

[0021] The advantages and positive effects of the present invention are:

[0022] 1. The vibration-resistant and easy-to-store adjustable damping paper holder mechanism of the present invention is suitable for message display and control equipment, and provides an easy-to-store adjustable damping paper holder mechanism for the control table of message display and control equipment in the defense field / harsh environment, so that it can perform message entry functions in vibration environments such as shipboard, vehicle and aircraft.

[0023] 2. The vibration-resistant and easy-to-store adjustable damping paper holder mechanism of the present invention is suitable for message display and control equipment. When working in a vibrating environment, it can clamp paper documents and facilitate the reading of message operators within their sight without blocking the display window of the message display and control equipment. When not in operation, the volume can be reduced and stored in a control table of limited size.

[0024] 3. The vibration-resistant and easy-to-store adjustable damping paper holder mechanism of the present invention is suitable for message display and control equipment. According to the vibration impact force in the environment (ship-mounted, vehicle-mounted, and airborne) where the message control equipment is located, it is adjusted through the spring top ball positioning and locking mechanism to provide the locking force when the damping paper holder is erected on the control table. This is completed before the spring top ball fixing frame and spring top ball are pre-installed. The spring top plug of the spring top ball is rotated by a tool to increase or decrease the axial space of the internal spring, apply different pressures to the spring and transmit them to the end top ball. When the damping paper holder is erected, the top ball will be inserted into the spring top ball groove at the bottom of the paper holder main rod of the damping paper holder. At this time, the pressure will be transmitted to the damping paper holder, so that it needs to apply a spring force greater than that from the top ball when lifting and closing, so as to achieve the purpose of locking. It is used to adapt to the vibration influence from the external (ship-mounted, vehicle-mounted, and airborne) environment in the erected state.

[0025] 4. The vibration-resistant adjustable damping paper holder mechanism of the present invention is suitable for storage of message display and control equipment. By adjusting the pre-tightening force of the M3×8 screws, it is used to provide friction when the left and right arms of the damping paper holder are lifted and closed, and to adjust the positive pressure between the pressure plate, damping sheet, main rod of the paper holder, left arm and right arm, thereby adjusting the friction during rotational motion.

[0026] 5. The vibration-resistant and adjustable damping paper holder mechanism of the present invention is suitable for storing message display and control equipment. Paper documents are adsorbed on the left and right arms by magnetic attraction, and the paper documents are clamped, making it convenient to lay out and take out the paper documents without the need for additional tools.

[0027] 6. The present invention is a vibration-resistant and easy-to-store adjustable damping paper holder mechanism suitable for message display and control equipment. A rectangular groove is provided on the left front side of the control table of the message display and control equipment. The damping paper holder by tightening the left arm and the right arm forms a strip structure, which can be hidden in the rectangular groove after being folded by rotating the paper holder axis. The damping paper holder is closed, locked and popped out by a spring locking mechanism; the damping paper holder is locked after popping out of the rectangular groove by a spring top ball positioning locking mechanism.

[0038] The present invention will be further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the scope of protection of the present invention cannot be limited thereto.

[0039] A vibration-resistant, easy-to-store adjustable damping paper holder mechanism suitable for message display and control equipment, the message display and control equipment comprising a display module 1, a KVM module 2, an alarm module 4, a control table 5, a keyboard module 6, a mouse module 7, a switch module 8 and a status display module 9; a rectangular groove is provided on the left front of the control table of the message display and control equipment, in which a spring locking mechanism, a spring top ball positioning locking mechanism, a damping paper holder 3 and a magnetic suction 11 are installed.

[0040] The spring locking mechanism includes a hook 12 , a long compression spring 14 , a button 13 and a short compression spring 18 ; the spring top ball positioning locking mechanism includes a top ball fixing frame 21 .

[0041] The damping paper rack 3 includes a paper rack main rod 3-3; the left and right ends of the top of the paper rack main rod 3-3 are respectively installed with a foldable left support arm 3-1 and a right support arm 3-4, the bottom of the paper rack main rod 3-3 is installed at one end of the groove, and the top of the paper rack main rod 3-3 is clamped in the groove through a hook 12 located at the other end of the groove. The paper rack main rod 3-3 pops out of the groove through a button 13 located at the front end of the hook 12, a long compression spring 14 and a short spring located in the middle of the groove.

[0042] A top bead fixing frame 21 is installed at the front end of the bottom of the paper rack main rod 3-3 installed at one end of the groove, and spring top beads 20 are installed on the left and right ends of the top bead fixing frame 21. The spring top beads 20 are clamped in the spring top bead grooves 3-12 located at the left and right ends of the bottom of the paper rack main rod 3-3 to lock the paper rack main rod 3-3.

[0043] The magnetic attraction 11 installed on the main rod 3-3 of the paper rack is removed and placed on the left support arm 3-1 and the right support arm 3-4 at the left and right ends of the top of the paper rack main rod 3-3, so that the paper document 10 is adsorbed on the left support arm 3-1 and the right support arm 3-4 at the left and right ends of the top of the paper rack main rod 3-3.

[0044] The left support arm 3-1 and the right support arm 3-4 are respectively installed on the left and right ends of the top of the paper rack main rod 3-3 through a fixed shaft 3-7 welded with a pressure plate 3-8, a damping sheet 3-5 and a damping sleeve 3-6, and are screwed on the paper rack main rod 3-3 through the pressure plate 3-8.

[0045] The paper rack main rod 3-3 is formed with a chamfered hook groove 3-9, a magnetic groove 3-10 and a short spring groove 3-11 from top to bottom; the chamfered hook groove 3-9 is clamped with a hook 12; the magnetic groove 3-10 is equipped with a magnet 11; and the short spring groove 3-11 is equipped with a short spring.

[0046] The bottom of the paper rack main rod 3-3 is installed on one end of the groove through the paper rack shaft 19.

[0047] The hook 12 is mounted on the other end of the groove via the shaft 17 .

[0048] The long compression spring 14 is screwed onto the front end of the hook 12 through a spring sleeve 16 and an M3×12 screw assembly 15 .

[0049] After the left support arm 3-1 and the right support arm 3-4 at the left and right ends of the top of the paper rack main rod 3-3 are folded, the folding damping paper rack 3 forms a strip structure and is placed in the groove opened on the control table of the message display and control device.

[0050] The spring top ball grooves 3-12 located at the left and right ends of the bottom of the paper rack main rod 3-3 are hemispherical spring top ball grooves 3-12.

[0051] Install the left support arm 3-1, and install the wear-resistant nylon PA66 damping plate 3-5 on one end of the fixed shaft 3-7 welded with the pressure plate 3-8. Then use special tools to press the interference fit damping sleeve 3-6 and the left support arm 3-1 onto the fixed shaft 3-7 welded with the pressure plate 3-8, and install the wear-resistant nylon PA66 damping plate 3-5 on the other end of the fixed shaft 3-7 welded with the pressure plate 3-8.

[0052] Install the right support arm 3-4, and set the damping plate 3-5 made of wear-resistant nylon PA66 on one end of the fixed shaft 3-7 welded with the pressure plate 3-8. Then use special tools to press the interference fit damping sleeve 3-6 and the right support arm 3-4 onto one end of the fixed shaft 3-7 welded with the pressure plate 3-8 and the damping plate 3-5 made of wear-resistant nylon PA66 on the other end of the fixed shaft 3-7 welded with the pressure plate 3-8.

[0053] Use M3×8 screws 3-2 to fasten the left support arm 3-1 and the right support arm 3-4 to the paper rack main rod 3-3.

[0054] Because the damping sleeve 3-6 is made of wear-resistant nylon PA66 and is installed through interference fit, it can provide a certain amount of damping after installation. In addition, the damping plates 3-5 at both ends of the damping sleeve 3-6 are also made of nylon PA66, which has wear-resistant properties. Because its material has a certain toughness, it can provide recoverable micro-deformation under the pressure from the pressure plate 3-8. By adjusting the preload force of the M3×8 screw 3-2, the friction between the end face of the damping sleeve 3-6, the end face of the left support arm 3-1, the end face of the right support arm 3-4, and the damping plate 3-5 can be changed to achieve the effect of variable damping, thereby strengthening the supporting force of the left support arm 3-1 and the right support arm 3-4 in the open state under vibration environment, and adapting to the vibration environment of ships, vehicles and aircraft.

[0055] By adjusting the pre-tightening force of the M3×8 screw 3-2, the friction force is provided when the left arm 3-1 and the right arm 3-4 of the damping paper holder 3 are lifted and closed, and the positive pressure between the pressure plate 3-8, the damping plate 3-5, the paper holder main rod 3-3, the left arm 3-1 and the right arm 3-4 is adjusted, thereby adjusting the friction force during the rotational movement.

[0056] After the left arm 3-1 and the right arm 3-4 are folded, the damping paper holder 3 is stored:

[0057] When the damping paper rack 3, with the left and right arms 3-1 and 3-4 folded, is fastened to the console 5 of the message display and control device, the main rod 3-3 rotates about the paper rack axis 19 toward the console 5. The chamfered hook groove 3-9 at the front end of the main rod 3-3 contacts the hook 12. The hook 12, under external pressure, rotates clockwise about the axis 17. After the main rod 3-3 is positioned in the rectangular groove on the left front of the message display and control device console, the hook 12, under pressure from the long compression spring 14, rotates counterclockwise about the axis 17. The hook 12 is then snapped into the chamfered hook groove 3-9 at the front end of the main rod 3-3, locking the main rod 3-3 in place. This allows the main rod 3-3 to be securely fixed in the rectangular groove on the left front of the message display and control device console when subjected to external vibrations (such as those from ships, vehicles, and aircraft). When the damping paper rack 3 is stored, the magnet 11 is installed in the magnetic groove 3-10 provided on the main rod 3-3. After the damping paper holder 3 is stored, the spring locking mechanism is used to prevent the damping paper holder 3 on the control table 5 of the message display and control device from jumping up in a vibration environment.

[0058] Lift the damping paper holder 3 after folding the left arm 3-1 and the right arm 3-4:

[0059] When the damping paper rack 3 needs to be lifted after the left arm 3-1 and the right arm 3-4 are folded, it is necessary to press the button 13. The pressure is transmitted to the hook 12 through the button 13. The hook 12 rotates clockwise around the axis 17 to disengage the paper rack main rod 3-3. The paper rack main rod 3-3 will be subjected to the upward push force from the short compression spring 18 and rotate counterclockwise around the paper rack axis 19 to pop out the rectangular groove opened on the left front of the control table of the message display and control device.

[0060] Lift the damping paper holder 3 after folding the left arm 3-1 and the right arm 3-4 and then lock it:

[0061] A ball holder 21 is mounted 10 mm from the front end of the paper holder shaft 19, located at the bottom of the paper holder main rod 3-3, at one end of the groove. Spring balls 20 with adjustable pressure are mounted on both ends of the ball holder 21. After the left and right arms 3-1 and 3-4 are folded and the damping paper holder 3 is raised counterclockwise around the paper holder shaft 19 to a vertical position, the spring balls 20 mounted on both ends of the ball holder 21 snap into place in the hemispherical spring ball grooves 3-12 at the left and right ends of the paper holder main rod 3-3, locking the damping paper holder 3 and preventing it from swinging around the paper holder shaft 19 due to vibration. The spring balls 20 mounted on both ends of the ball holder 21 and the spring ball grooves 3-12 at the left and right ends of the paper holder main rod 3-3 can be adjusted in diameter and pressure to accommodate different external vibration environments (such as those on ships, vehicles, and aircraft). To retract the damping paper holder 3, a clockwise force greater than the locking force of the spring bead 20 is applied to the damping paper holder 3, disengaging the spring bead 20 and allowing the damping paper holder 3 to rotate about the paper holder axis 19 until closed. When the damping paper holder 3 is in an upright position, the spring bead locks the mechanism in place, preventing it from vibrating about the paper holder axis 19 and potentially failing due to vibration.

[0062] Lift and lock the damping paper holder 3 after folding the left arm 3-1 and the right arm 3-4, and then work on the control panel 5:

[0063] When the damping paper holder 3 is erected on the control table 5, after the damping paper holder 3 is erected and locked in place by the spring top ball 20, the magnet 11 installed in the magnetic groove 3-10 of the paper holder main rod 3-3 is removed, and an external force is applied to the left arm 3-1 and the right arm 3-4, so that they can rotate around the fixed axis 3-7 and unfold to a suitable position. The paper document 10 is placed on the unfolded left arm 3-1 and the right arm 3-4, and the paper document 10 is attracted to the left arm 3-1 and the right arm 3-4 by the magnet 11, thereby clamping the paper document 10. The reporter compares the message on the paper document 10 and enters the message through the keyboard module 6 and the mouse module 7. Because the magnet 11 is easy to take, the reporter can adjust the position of the paper document 10 according to different control tables to facilitate reading and identification.

[0064] According to the vibration and impact force in the environment (ship-mounted, vehicle-mounted, and aircraft-mounted) in which the message control equipment is located, the spring top ball positioning and locking mechanism is adjusted to provide a locking force for the damping paper rack 3 when it is erected on the control table. This is completed before the spring top ball fixing frame 21 and the spring top ball 20 are pre-installed. The spring top plug of the spring top ball 20 is rotated by a tool to increase or decrease the axial space of the internal spring, apply different pressures to the spring and transmit them to the end top ball. When the damping paper rack 3 is erected, the top ball will be inserted into the spring top ball groove 3-12 at the bottom of the paper rack main rod 3-3 of the damping paper rack 3. At this time, the pressure will be transmitted to the damping paper rack 3, so that it needs to apply a spring force greater than that from the top ball when it is lifted and closed, so as to achieve the purpose of locking. It is used to adapt to the vibration influence from the external environment (ship-mounted, vehicle-mounted, and aircraft-mounted) in the erected state.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
