Description

Technical Field

[0001] The present invention belongs to the technical field of signal chassis, and particularly relates to a chassis with a movable mounting plate. Background Art

[0002] At present, signal chassis on the market are divided into two categories: board cards or power distribution. Motherboards, printed circuit boards, etc. are installed inside the above two types of chassis. During use, the motherboards and printed circuit boards installed inside the chassis need to go through assembly line processes with external devices. The interfaces between the existing chassis and external devices are all connected through electronic components arranged on the adapter mounting plate. For example, when lightning protection is required, it needs to be connected to the connected lightning protection module; when a switch needs to be connected, it needs to be connected to the air switch; when external wiring is required, it needs to be connected to the wiring terminal. The adapter mounting plate assembly is designed separately and is independent of the chassis. The existing adapter mounting plate with components is generally arranged outside the chassis. In this way, wiring assembly is required between the chassis and the mounting plate assembly, and it is led to the motherboards and printed circuit boards inside the chassis through the vertical wire grooves and horizontal wire grooves between the cabinets where the chassis is located, increasing a lot of extra wiring. The wiring is cumbersome, the space volume is messy, the wiring amount is large, and at the same time, fasteners are required for the installation of the mounting plate assembly, which is not convenient for disassembly and assembly. Once the position of the mounting plate is adjusted, the wiring needs to be adjusted accordingly, resulting in waste of raw materials. Summary of the Invention

[0003] In view of the above-mentioned disadvantages and deficiencies of the prior art, the present invention provides a chassis with a movable mounting plate, which integrates the mounting plate with the transfer module on the chassis to reduce the installation space and reduce the wiring; by setting the mounting plate to be movable, it is convenient for wiring and storage.

[0004] In order to achieve the above purpose, the main technical solutions adopted by the present invention include:

[0007] Further, an arc is provided at the rear end of the slideway to facilitate the turning movement of the mounting plate at the rear end of the slideway.

[0008] Furthermore, the locking mechanism includes a rotatable hinge and a connecting rod. The rotatable hinge is arranged on the edge of the mounting plate perpendicular to the side plate. A hanging plate is provided on the rotatable hinge, and a check spring is provided inside. The check spring enables the hanging plate to rotate within a range of 90°. When the check spring is relaxed, the hanging plate is arranged toward the inner side of the box body relative to the mounting plate plane. Both ends of the connecting rod are connected to the inner side of the side plate. The connecting rod includes a first connecting rod, a second connecting rod, and a third connecting rod. The first connecting rod and the second connecting rod are respectively arranged on the front and rear sides of the upper part of the side plate flange, and the third connecting rod is arranged at the rear bottom of the side plate flange. The first connecting rod, the second connecting rod and the plane when the mounting plate is at the top of the side plate are parallel, and the second connecting rod and the third connecting rod are parallel to the plane when the mounting plate is at the rear of the side plate. The hanging plate is connected to the connecting rod for clamping and loading and unloading. When the mounting plate is placed on the top of the box body, the hanging plates on both sides of the mounting plate are connected with the first connecting rod and the second connecting rod, so that the mounting plate is fixed on the top of the box body; when the mounting plate is placed at the rear of the box body, the hanging plates on both sides of the mounting plate are connected with the second connecting rod and the third connecting rod, so that the mounting plate is fixed at the rear of the box body; before moving the mounting plate, the hanging plates can be manually opened to separate them from the connecting rods to move the mounting plate, which is convenient for moving and fixing the mounting plate.

[0009] Furthermore, the connecting rod is in the shape of a round rod, and a slot is provided on it at a corresponding position of the hanging plate. The hanging plate is provided with a hook matching the connecting rod slot. The hook is connected to the slot for locking and loading and unloading. The slot limits the hook so that the hanging plate and the connecting rod are locked and firmly connected.

[0010] Furthermore, the hook opening directions of the hanging plates on both sides of the mounting plate are arranged so that when the mounting plate is located on the top of the box body, the hook openings are all arranged backwards, which is convenient for operation.

[0011] Furthermore, the locking mechanism also includes a connecting rod moving device, which enables the connecting rod to move and connect with the hanging plate card for loading and unloading, making the connecting rod and the hanging plate card more convenient and easy to operate.

[0012] Further, the connecting rod moving device is a retractable pusher, which is arranged at both ends of the connecting rod and connected to the side plate, and the retractable pusher includes a shell and a push rod, and the shell is provided with a connecting rod moving groove, a first installation groove, and a second installation groove, and the second installation groove and the connecting rod moving groove are located on the same straight line, and the first installation groove and the second installation groove are arranged vertically, and a first spring and a push rod are arranged in the first installation groove, and a second spring and a second push plate are arranged in the second installation groove, and a first push plate is arranged at one end of the push rod, and the first push plate abuts against the first spring, and the other end of the push rod is placed outside the shell, and a through groove is arranged in the middle of the first push plate, and the through groove is passed through by the second spring and the second push plate, and the connecting rod is placed in the connecting rod moving groove. The mounting plate contacts the push rod, compresses the first spring, and makes the through groove align with the position of the second spring, and the second spring drives the second push plate to pop up, and pushes the connecting rod in the connecting rod moving groove upward, so that the connecting rod is connected with the hanging plate, and the operation of manually installing the hanging plate is reduced.

[0013] Furthermore, when the mounting plate is placed on the top of the side plate flange, the distance from the mounting plate to the top of the back plate is equal to the distance from the mounting plate to the back of the back plate when the mounting plate is placed at the rear of the side plate flange. This arrangement ensures that after the mounting plate is installed, whether the mounting plate is on the top of the box or at the rear of the box, the wiring distance between the mounting plate and the components in the box is consistent, and the problem of insufficient wiring due to the movement of the mounting plate will not occur.

[0014] Furthermore, the mounting plate is provided with threading holes and handles to facilitate installation operations.

[0015] The beneficial effects of the present invention are:

[0016] 1. The chassis with a movable mounting plate of the present invention can save installation space, wiring and cost by integrating the mounting plate with the switching components on the chassis and moving, fixing and using the mounting plate according to actual conditions;

[0017] 2. When the mounting plate of the present invention is placed on the top of the side plate flange, the distance from the mounting plate to the top of the back plate is equal to the distance from the mounting plate to the back of the back plate when the mounting plate is placed at the rear of the side plate flange.

Detailed implementation manners

[0035] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] The present invention provides a chassis with a movable panel, such as Figure 1-2 As shown, it includes a box structure. The conventional rectangular box structure chassis part is a standard U chassis. The number of U can be freely set. The present invention sets the side panels of the conventional rectangular box structure to have a side panel flange 1-1 extending to the rear and upward at the rear. It also includes a mounting plate 2 for installing electronic components. The electronic components described here are switching components, such as lightning protection modules, switches, terminal blocks, etc. The mounting plate 2 is slidably connected to the side panel flange 1-1. The mounting plate 2 moves from the top to the rear on the side panel flange 1-1. It also includes a locking mechanism 3. The locking mechanism 3 is used to fix the mounting plate 2. The directional terms such as "above" and "rear" described in this article are based on the meaning of the invention. Figure 1 The orientation is used as a reference, and the box is used as a reference to define the top of the box, the back of the box, Figure 1 This is a schematic diagram of the installation board 2 being on top of the box. Figure 2 It is a schematic diagram when the mounting plate 2 is located at the rear of the box. By integrating the transfer components on the box through the mounting plate 2, the problem of previously designing the transfer mounting plate assembly separately and independently of the chassis is overcome. The wiring assembly needs to be performed between the chassis and the mounting plate assembly, which adds a lot of additional wiring, is cumbersome in wiring, and is messy in space and volume. The wiring amount is large, which causes the problem of waste of raw materials. The present invention integrates the mounting plate 2 equipped with the transfer components on the box. The mounting plate 2 can be moved within the range from the top to the rear of the box. The position of the mounting plate 2 can be fixed by the locking mechanism 3 according to the actual installation position. It can also be used flexibly. When the transfer components are not needed, the mounting plate 2 is fixed to the top of the box, and the components inside the box are directly wired through the back plate of the box, or no wiring is required. When the components in the box need to be connected through the transfer components, the mounting plate is moved to the rear of the box and fixed, and the connection between the components is realized by cooperating with the threading holes 2-1 set on the mounting plate 2. The mounting plate 2 can also be placed above the box to connect the components. The present invention integrates the mounting plate 2 equipped with the switching components on the box body, and moves, fixes and uses the mounting plate 2 according to actual conditions, thereby saving installation space, wiring and cost. Figure 4-5 As shown, the mounting plate 2 is provided with a threading hole 2-1. The mounting plate 2 is provided with a handle 2-2.

[0037] More specifically, when the mounting plate 2 is placed on the top of the side plate flange 1-1, the distance from the mounting plate 2 to the top of the back plate is equal to the distance from the mounting plate 2 to the back of the back plate when the mounting plate 2 is placed behind the side plate flange 1-1. The back plate is at the same height as the front plate and the rectangular part of the side plate. This arrangement ensures that after the mounting plate is installed, whether the mounting plate is on the top of the box or at the rear of the box, the wiring distance between the mounting plate and the components in the box is consistent, and the problem of insufficient wiring due to the movement of the mounting plate will not occur.

[0038] Specifically, Figure 3 As shown, the side panel 1 is an L-shaped side panel flange 1-1 integrally formed at the rear of the original rectangular side panel, and the L-shaped side panel flange 1-1 is an inverted L-shape extending toward the rear and upper part of the box body. A slide 1-2 is provided on the inner side of the upper part of the L-shaped side panel flange 1-1, and the slide 1-2 is used to provide a sliding track and support for the mounting plate 2. In order to facilitate the rotation of the mounting plate 2, the rear end of the slide 1-2 is set to an arc structure, so that the mounting plate 2 can turn and move at the rear end of the slide.

[0039] The locking mechanism 3 includes a rotatable hinge 3-1 and a connecting rod 3-2. The rotatable hinge 3-1 is arranged on the side of the mounting plate 2 perpendicular to the side plate 1. Figure 6 , 7 As shown, the rotatable hinge 3-1 is provided with a hanging plate 3-1-1, and a check spring is provided inside. The check spring makes the hanging plate 3-1-1 rotate within a range of 90°. When the check spring is relaxed, the hanging plate 3-1-1 is arranged toward the inner side of the box body relative to the plane of the mounting plate 2. The hook opening directions of the hanging plates on both sides of the mounting plate 2 are arranged so that the hook openings are all arranged toward the rear when the mounting plate 2 is located at the top of the box body. The two ends of the connecting rod 3-2 are connected to the inner side of the side plate 1. The connecting rod 3-2 includes a first connecting rod, a second connecting rod, and a third connecting rod. The first connecting rod and the second connecting rod are respectively arranged at the front and rear sides of the upper part of the side plate flange 1-1, and the third connecting rod is arranged at the rear bottom of the side plate flange 1-1. The first connecting rod and the second connecting rod are parallel to the plane when the mounting plate 2 is at the top of the side plate 1, and the second connecting rod and the third connecting rod are parallel to the plane when the mounting plate 2 is at the rear of the side plate 1. The hanging plate 3-1-1 is connected to the connecting rod 3-2 for clamping and loading and unloading. When the mounting plate 2 is placed on the top of the box, the hanging plates 3-1-1 on both sides of the mounting plate 2 are connected with the first connecting rod and the second connecting rod, so that the mounting plate 2 is fixed on the top of the box; when the mounting plate 2 is placed at the rear of the box, the hanging plates 3-1-1 on both sides of the mounting plate 2 are connected with the second connecting rod and the third connecting rod, so that the mounting plate 2 is fixed at the rear of the box; before moving the mounting plate 2, the hanging plates 3-1-1 can be manually opened to separate them from the connecting rod 3-2 to move the mounting plate 2, which is convenient for moving and fixing the mounting plate 2.

[0040] Specifically, Figure 8As shown, the connecting rod 3-2 is a round rod, and a slot 3-2-1 is provided on it at a position corresponding to the hanging plate 3-1-1. The hanging plate 3-1-1 is provided with a hook matching the connecting rod slot 3-2-1, and the hook is connected with the slot 3-2-1 for loading and unloading. The slot 3-2-1 limits the hook, so that the hanging plate 3-1-1 and the connecting rod 3-2 are firmly locked.

[0041] In order to facilitate operation, the locking mechanism 3 also includes a connecting rod moving device, which moves the connecting rod 3-2 to engage with the hanging plate 3-1-1 for loading and unloading. The connecting rod 3-2 is actively engaged with the hanging plate 3-1-1, which saves part of the manual operation of bending the rotatable hinge 3-1, making it more convenient and easy to operate.

[0042] Specifically, Figure 9-13 As shown, the connecting rod moving device is a retractable pusher 3-3, and the retractable pusher 3-3 is arranged at both ends of the connecting rod 3-2 and connected to the side plate 1. The retractable pusher 3-3 includes a shell 3-3-1 and a push rod 3-3-2. The shell is provided with a connecting rod moving groove 3-3-3, a first mounting groove 3-3-4, and a second mounting groove 3-3-5. The second mounting groove 3-3-5 and the connecting rod moving groove 3-3-3 are located on the same straight line. The first mounting groove 3-3-4 and the second mounting groove 3-3-5 are vertically arranged. A first spring 3-3-3 is arranged in the first mounting groove 3-3-4. 6 and a push rod 3-3-2, a second spring 3-3-7 and a second push plate 3-3-8 are arranged in the second mounting groove 3-3-5, a first push plate 3-3-2-1 is arranged at one end of the push rod 3-3-2, the first push plate 3-3-2-1 abuts against the first spring 3-3-6, the other end of the push rod 3-3-2 is placed outside the shell 3-3-1, a through groove 3-3-2-2 is opened in the middle of the first push plate 3-3-2-1, the through groove 3-3-2-2 is for the second spring 3-3-7 and the second push plate 3-3-8 to pass through, and the connecting rod 3-2 is placed in the connecting rod moving groove 3-3-3. When in use, it is only necessary to make the mounting plate 2 contact the push rod 3-3-2 to compress the first spring 3-3-6, so that the through groove is aligned with the position of the second spring 3-3-7, and the second spring 3-3-7 drives the second push plate 3-3-8 to pop out, pushing the connecting rod 3-2 in the connecting rod moving groove 3-3-3 upward, so that the connecting rod 3-2 is clamped and connected with the hanging plate 3-1-1. When resetting, manually press down the connecting rod 3-2 to compress the second spring 3-3-7, and the first spring 3-3-6 is released, driving the first push plate 3-3-2-1 to clamp the connecting rod 3-2, so that the connecting rod 3-2 is fixed at the lower end of the connecting rod moving groove 3-3-3, waiting to be triggered again, thereby reducing the operation of manually installing the hanging plate.

[0043] When in use, if you want to fix the mounting plate 2 on the upper part of the box, move the mounting plate 2 along the slide 1-2 to the upper part of the box, and manually rotate the rotatable hinge 3-1 to make the hanging plate 3-1-1 engage with the slots 3-2-1 of the first connecting rod and the second connecting rod. The hanging plates 3-1-1 all face the rear of the box and are set vertically downward. When the mounting plate 2 is to be released for movement, the hanging plate 3-1-1 of the rotatable hinge 3-1 is manually pried open to separate the rotatable hinge 3-1 from the connecting rod 3-2, and the hanging plate 3-1-1 is restored to a position perpendicular to the mounting plate 2 under the reset of the check spring. After the mounting plate 2 is moved backward, the mounting plate 2 is rotated downward. At this time, the mounting plate 2 is turned from horizontal to vertical and placed at the rear of the box body. At this time, the hanging plates 3-1-1 located at the upper and lower parts of the mounting plate 2 are turned downward, and the upper hanging plate 3-1-1 of the mounting plate 2 is manually clamped on the second connecting rod, and the lower part of the mounting plate 2 abuts against the push rod 3-3-2 of the retractable pusher 3-3. The first spring 3-3-6 is compressed to align the through groove with the position of the second spring 3-3-7. The second spring 3-3-7 drives the second push plate 3-3-8 to pop out, pushing the connecting rod 3-2 in the connecting rod moving groove 3-3-3 upward, so that the connecting rod 3-2 is clamped and connected with the hanging plate 3-1-1 to complete the fixation. When resetting, manually press down the connecting rod 3-2 to compress the second spring 3-3-7 and release the first spring 3-3-6, driving the first push plate 3-3-2-1 to clamp the connecting rod 3-2, so that the connecting rod 3-2 is fixed at the lower end of the connecting rod moving groove 3-3-3, waiting to be triggered again, reducing the operation of manually installing the hanging plate.
