Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a cabinet telescopic device and a cabinet. Background Art

[0002] Cabinets are commonly used equipment for communication signals. Cabinets are generally installed in communication or signal control rooms and are used to install electrical equipment or electrical components such as routers, industrial computers, monitors, keyboards, and mice.

[0003] In cabinet products, the telescopic device is a commonly used component. It is similar to a drawer, and its main function is to place the keyboard and mouse used to operate the industrial computer.

[0004] In order to ensure that the extended state is long enough, the existing cabinet extension device will set a margin for the keyboard cable and the mouse cable. When the cabinet extension device is in the retracted state, the margin of the keyboard cable and the mouse cable is uncontrolled, and they are naturally hung in the cabinet due to gravity. In this way, the keyboard cable and the mouse cable and other wires may be scratched or squeezed by other parts in the cabinet during repeated extension and retraction, causing the wires to be damaged, which in turn causes the equipment products connected to the wires to fail and cannot work normally.

[0005] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a cabinet expansion device and a cabinet in view of the technical defects in the prior art.

[0007] To this end, the present invention provides a cabinet telescopic device, comprising horizontally distributed trays;

[0008] The tray is arranged in a cabinet body so as to be movable forward and backward;

[0009] At least one device is placed on top of the tray;

[0010] Each electrical device is provided with exposed wires;

[0011] Each wire is connected to a wire hub installed on the cabinet body;

[0012] The wire collecting device is used to release the wires on the electrical equipment when the tray moves forward, so that the wires move with the tray, and to wind and gather the wires on the electrical equipment when the tray moves backward, so that the wires move with the tray;

[0013] Wherein, the line hub device comprises a hollow line hub device housing;

[0014] The housing of the wire collection device is provided with a wire accommodating cavity and a spring accommodating cavity which are spaced apart from each other in the front and rear;

[0015] A wire collection barrel is arranged in the wire accommodating cavity;

[0016] A portion of the wire is wound around the circumferential side wall of the wire hub;

[0017] A volute spring is arranged in the spring accommodating cavity;

[0018] The hub is connected to one end of the volute spring via a longitudinally distributed intermediate shaft;

[0019] The other end of the spiral spring is fixedly connected to the inner wall of the spring accommodating cavity;

[0020] The intermediate shaft longitudinally penetrates through the intermediate partition between the wire receiving cavity and the spring receiving cavity.

[0021] It can be seen from the technical solution provided by the present invention that, compared with the prior art, the present invention provides a cabinet telescopic device and a cabinet, which have a scientific structural design. By setting a wire collection device, the wires such as coiled cables and mouse cables that need to be telescopic in the cabinet can be protected to prevent the wires from falling in the cabinet uncontrollably, thereby preventing the wires from being scratched or squeezed by other components in the cabinet and causing damage to the wires, which is beneficial to ensuring the reliable operation of electrical equipment on the cabinet and has great practical significance.

[0022] By applying the present invention, the problem that the cabinet telescopic device cannot protect keyboard cables, mouse cables and other wires when in the retracted state can be effectively solved. The present invention gathers the keyboard cables and mouse cables in a cable collection device when the telescopic device is retracted, thereby achieving the purpose of protection.

[0038] See also Figure 1 , Figure 2a to Figure 2e , Figures 3 to 7 , the present invention provides a cabinet telescopic device, comprising a horizontally distributed tray 5;

[0039] The tray 5 is arranged in a cabinet body 10 so as to be movable forward and backward (i.e., telescopically);

[0040] At least one electrical device is placed on top of the tray 5;

[0041] Each electrical device is provided with exposed wires 9;

[0042] Each wire 9 is connected to a wire collection device 1 installed on the cabinet body 10;

[0043] The wire collection device 1 is used to release the wires 9 on the electrical equipment when the tray 5 moves forward (i.e. extends outward), so that the wires 9 move with the tray 5, and to wind and gather the wires 9 on the electrical equipment when the tray 5 moves backward (i.e. retracts), so that the wires 9 move with the tray 5;

[0044] The line hub device 1 includes a hollow line hub device housing 104;

[0045] The housing 104 of the wire collection device has a wire accommodating cavity 1041 and a spring accommodating cavity 1042 which are spaced apart from each other in the front and back.

[0046] A wire collection barrel 102 is disposed in the wire accommodating cavity 1041;

[0047] A portion of the wire 9 (specifically, a portion of the middle section, which is not the portion at the head and tail ends) is wound around the circumferential side wall of the wire hub 102;

[0048] The spring accommodating cavity 1042 is provided with a spiral spring 101;

[0049] The hub 102 is connected to one end (i.e., the inner end) of the spiral spring 101 through a longitudinally distributed intermediate shaft 103;

[0050] The other end (ie, the outer end) of the spiral spring 101 is fixedly connected to the inner wall of the spring accommodating cavity 1042 .

[0051] The intermediate shaft 103 longitudinally penetrates through the intermediate partition 106 between the wire receiving cavity 1041 and the spring receiving cavity 1042;

[0052] It should be noted that the intermediate shaft 103 is located in the inner hole of the spiral spring 101 and is fixedly connected to one end (ie, the inner end) of the spiral spring 101 .

[0053] In the present invention, in a specific implementation, the intermediate shaft 103 is pivotally connected (ie, rotatably connected) in the housing 104 of the line hub.

[0054] In specific implementation, the spacer plate 106 is provided with an intermediate shaft through hole at a position corresponding to the intermediate shaft 103;

[0055] A first bearing is arranged on the intermediate shaft through hole;

[0056] The intermediate shaft 103 is connected to the inner ring of the first bearing and penetrates through the inner ring of the first bearing in the longitudinal direction.

[0057] In a specific implementation, the front end of the intermediate shaft 103 longitudinally passes through the wire hub 102 and is pivotally connected (i.e., rotatably connected) to the front side wall of the wire accommodating cavity 1041;

[0058] Further, a second bearing is provided on the front side wall of the wire accommodating cavity 1041;

[0059] The inner ring of the second bearing is connected to the front end of the intermediate shaft 103 .

[0060] In specific implementation, the rear end of the intermediate shaft 103 longitudinally passes through the inner hole of the spiral spring 101 and is pivotally connected (i.e., rotatably connected) to the rear side wall of the spring accommodating cavity 1042;

[0061] Further, a third bearing is provided on the rear side wall of the spring receiving cavity 1042;

[0062] The inner ring of the third bearing is connected to the rear end of the intermediate shaft 103 .

[0063] Therefore, based on the above design, the intermediate shaft 103 can be pivotally connected in the cable hub housing 104 to ensure that it can rotate clockwise and counterclockwise under the action of external force.

[0064] In the present invention, in a specific implementation, the wire collection device housing 104 is provided with two wire passing holes 1040 at positions corresponding to the wire collection barrel 102;

[0065] The wire through hole 1040 is used to pass the wire 9 through;

[0066] The wire passage hole 1040 is directly connected to the wire accommodating cavity 1041;

[0067] In a specific implementation, the two wire passage holes 1040 are distributed symmetrically around the center.

[0068] In a specific implementation, the line connecting the wire hub 102 and the center points of the two wire passing holes 1040 is located on the same straight line.

[0069] In the present invention, in a specific implementation, the overall shape of the hub 102 is cylindrical.

[0070] In the present invention, in order to allow the tray 5 to be arranged in the cabinet body 10 in a movable manner (i.e., telescopic manner) forward and backward, the specific structure is designed as follows:

[0071] The cabinet body 10 is a hollow cabinet body;

[0072] The cabinet body 10 is provided with a left longitudinal beam 31 and a right longitudinal beam 62 which are symmetrically distributed on the left and right sides;

[0073] The opposite side (ie the inner side) of the left longitudinal beam 31 and the right longitudinal beam 62 is connected to the left and right sides of the tray 5 through a longitudinally distributed drawer guide rail 4, respectively.

[0074] In a specific implementation, the opposite sides of the left longitudinal beam 31 and the right longitudinal beam 62 are respectively connected to the guide rail portion of a drawer guide rail 4;

[0075] The slider parts on the two drawer guide rails 4 are connected to the left and right sides of the tray 5 .

[0076] It should be noted that the drawer guide rail 4 is a linear slide rail (also known as a guide rail or a slideway), which is a common component installed on a cabinet body and a common hardware connection component for the drawer to extend and retract. The slider portion on the linear guide rail can slide along the guide rail portion. Through the drawer guide rail 4, the tray 5 and the objects placed on the tray 5 can be easily moved in the front and rear directions.

[0077] In specific implementation, the left longitudinal beam 31 and the right longitudinal beam 62 are connected on opposite sides by a transversely distributed cross beam 2;

[0078] The crossbeam 2 is located behind the drawer rail 4;

[0079] The cable collection device 1 is installed on the crossbeam 2 .

[0080] In specific implementation, the left longitudinal beam 31 and the right longitudinal beam 62 are respectively fixedly connected to the cross beam 2 by welding;

[0081] It should be noted that the left longitudinal beam 31 and the right longitudinal beam 62 can be respectively installed on the inner side walls of the left and right cabinet panels of the cabinet body 10 by fastening screws. For the present invention, the overall structure composed of the left longitudinal beam 31, the right longitudinal beam 62 and the cross beam 2 can be easily installed on the cabinet body 10.

[0082] Specifically, at both ends of the集线装置壳体104, a screw through hole 105 is respectively provided;

[0083] The集线装置1 is fixedly connected to the cross beam 2 in the机柜柜体10 through screws.

[0084] Furthermore, at positions corresponding to each screw through hole 105 on the cross beam 2, a threaded connection hole is respectively provided;

[0085] After the screw passes through the screw through hole 105 on the集线装置壳体104, it is threadedly fixedly connected to the threaded connection hole on the cross beam 2.

[0086] In the present invention, specifically, a keyboard 7 and a mouse 8 are placed on the top of the tray 5;

[0087] The wires 9 on the keyboard 7 and the wires 9 on the mouse 8 are respectively connected to a集线装置1.

[0088] It should be noted that for the present invention, the electrical devices placed on the top of the tray 5 are not limited to keyboards and mice, and may also include devices or electrical components such as a handwriting input board that the user wants to place and the tray 5 can support.

[0089] In the present invention, specifically, at the middle position on the front side of the tray 5, a handle 6 is provided to facilitate pulling the tray 5 out of the机柜柜体 and pushing the tray 5 into the机柜柜体.

[0090] Specifically, the shape of the handle 6 is U-shaped or "凵"-shaped.

[0091] To more clearly understand the technical solution of the present invention, the working principle of the present invention is described below.

[0092] Figure 3 Schematic diagram of the installation state when a机柜伸缩装置 provided by the present invention is installed in a机柜; Figure 4 Schematic diagram of the structure of a机柜伸缩装置 provided by the present invention when in the retracted state; Figure 5 Schematic diagram of the cross-sectional structure of the集线装置 when a机柜伸缩装置 provided by the present invention is in the retracted state; Figure 6 Schematic diagram of the structure of a机柜伸缩装置 provided by the present invention when in the extended state; Figure 7 Schematic diagram of the cross-sectional structure of the集线装置 when a机柜伸缩装置 provided by the present invention is in the extended state.

[0093] See Figure 4 、 Figure 5As shown, when the tray 5 in the cabinet telescopic device is in a retracted state, the spiral spring 101 is in a relaxed state, and the keyboard cable, mouse cable and other wires 9 are wound around the hub 102;

[0094] See also Figure 6 , Figure 7 As shown, when the tray 5 in the cabinet telescopic device is gradually pulled forward, the spiral spring 101 is gradually tightened, and the wires 9 (such as keyboard wires and mouse wires) on the wire collection barrel 102 are gradually released until they are extended into place (i.e., the tray 5 stops being pulled out);

[0095] When the tray 5 in the cabinet telescopic device is retracted (i.e. pushed backward), under the tensioning force of the spiral spring 101, a part of the wires 9 such as the keyboard cable and the mouse cable are retracted and gathered into the wire hub shell 104 and are wound around the wire hub 102. At this time, a part of each wire 9 (such as the keyboard cable and the mouse cable) (i.e. the remaining part of the wire) is gathered and fixed in the wire hub 1, which effectively prevents the remaining part of the wire 9 from falling into the internal space of the cabinet due to gravity, and prevents the remaining part of the wire 9 from being scratched or squeezed by other components in the cabinet, thereby preventing the wire from being damaged, thereby achieving the purpose of protecting the wire and ensuring the normal operation of the equipment in the cabinet.

[0096] Based on the above cabinet expansion device provided by the present invention, see Figure 3 As shown, the present invention also provides a cabinet, which includes a cabinet body 10;

[0097] At least one cabinet extension device as described above is arranged in the cabinet body 10 .

[0098] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
