[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0035] Reference Figure 1 to Figure 10 , which is the first embodiment of the present invention, and this embodiment provides a snap-on fireproof cable bridge, including a bridge body 100 and a locking mechanism 200, wherein the bridge body 100 includes a bridge seat 101 and a cover plate 103, and the cover plate 103 is fixed on the top of the bridge seat 101 by the locking mechanism 200, and an installation groove is provided between the bridge seat 101 and the cover plate 103, which can install and fix the cable, and adopts a snap-on design, which significantly simplifies the disassembly and installation process of the cover plate, improves the efficiency of installation and maintenance, and is also easy to operate in a space-constrained environment, reducing the manpower and time cost required for maintenance.

[0036] Specifically, fixed blocks 102 are symmetrically installed on the left and right sides of the upper end of the bridge seat 101, and a fixed plate 104 is fixedly installed in the middle of the top of the cover plate 103. The insides of the two fixed blocks 102 are both provided with docking grooves 102a, and the front and rear sides of the bottom end of the docking grooves 102a are symmetrically provided with card slots 102b.

[0037] More specifically, the locking mechanism 200 includes a docking plate 201 fixedly mounted on the left and right sides of the bottom end of the cover plate 103, and telescopic grooves 201a are symmetrically provided on the front and rear sides of the bottom of the two docking plates 201. The inner walls of each of the two front-and-rear symmetrical telescopic grooves 201a are fixedly connected with telescopic springs 202, and the opposite ends of the two telescopic springs 202 are fixedly connected with a clamping block 203. The top of each of the two front-and-rear symmetrical telescopic grooves 201a is provided with a moving groove 201b, and the inside of the moving groove 201b is slidably connected with a moving plate 204, the bottom end of the moving plate 204 is fixedly connected to the top wall of the clamping block 203, and the top of the moving plate 204 is transmission-connected with a toggle assembly 205.

[0038] Specifically, after the cover plate 103 is inserted into the docking grooves 102a of the two fixed blocks 102 through the two docking plates 201 at the bottom, the clamping ends of the clamping blocks 203 on the front and rear sides of the two docking plates 201 are clamped and fixed to each other with the clamping grooves 102b on the front and rear sides of the docking grooves 102a, thereby fixing the cover plate 103 to the bridge seat 101, and the toggle assembly 205 in the locking mechanism 200 can drive the two movable plates 204 to move horizontally relative to each other during operation, and the two movable plates 204 can drive the two clamping blocks 203 at the bottom to move toward the inside of the telescopic groove 201a, and after the clamping ends of the two clamping blocks 203 are completely moved out of the clamping grooves 102b, the relative fixation between the docking plate 201 and the fixed block 102 is released, so that the cover plate 103 can be removed from the bridge seat 101.

[0039] like Fig. 9 As shown, the block 203 includes a clamping portion a1 and a moving portion a2. The clamping portion a1 is arranged on the outside of the docking plate 201 and is used to be inserted into the card slot 102b to achieve the limiting fixation of the docking plate 201. The moving portion a2 is arranged in the telescopic slot 201a and is connected to the telescopic spring 202 to provide the card block 203 with telescopic space and elastic force. The moving plate 204 is fixedly installed on the top of the moving portion a2. The movement of the moving portion a2 and the clamping portion a1 is achieved by operating the toggle assembly 205. The clamping portion a1 is designed as a triangular block, which cooperates with the card slot 102b of the triangular groove to ensure that the top surface of the clamping portion a1 is tightly against the inner top wall of the card slot 102b, thereby achieving a firm limiting fixation. Through this design, the locking mechanism 200 can more stably and reliably fix the cover plate 103 and the bridge seat 101, and it can also be easily and quickly operated when disassembly is required, further simplifying the maintenance process.

[0040] It should be noted that the front and rear sides of the top of the docking groove 102a are symmetrically provided with arc surfaces. The design of this structure enables the docking plate to automatically dock with the fixing block 102 when inserted into the docking groove 102a, thereby making the installation process of the cover plate 103 and the bridge seat 101 more convenient. Specifically, when installing the cover plate 103, the staff only needs to align the two docking plates 201 at the bottom of the cover plate 103 with the docking grooves 102a opened at the top of the two fixing blocks 102, and then press the cover plate 103 vertically. The card block 203 can first be squeezed into the telescopic groove 201a along the arc surface, and then after the docking plate 201 is fully inserted into the docking groove 102a, under the action of the rebound force of the telescopic spring 202, the two card blocks 203 can be popped out from the telescopic groove 201a, and the clamping part a1 of the card block 203 can be inserted into the card slot 102b, and the top surface of the card block 203 can be against the inner top wall of the card slot 102b, so that the docking plate 201 is fixed in the fixed block 102, that is, the fixed installation of the cover plate 103 and the bridge seat 101 is relatively realized.

[0041] Furthermore, a stretching groove 104a is opened in the middle of the front side of the fixed plate 104, and the stretching groove 104a is used to accommodate and guide some parts of the toggle assembly 205. The left and right sides of the stretching groove 104a are connected with through grooves 104b, and the through grooves 104b are used to guide the movement of the toggle assembly 205 between different positions. The other ends of the two through grooves 104b are connected with rotating cavities 104c, and the rotating cavity 104c is used to accommodate and support the rotating parts of the toggle assembly 205. The parts of the toggle assembly 205 are respectively arranged in the stretching groove 104a, the through groove 104b and the rotating cavity 104c. Through the connection of these grooves and cavities, the toggle assembly 205 can be operated smoothly, thereby realizing the quick disassembly and installation of the cover plate 103, and improving the convenience and efficiency of maintenance.

[0042] Specifically, the toggle assembly 205 includes a rotating rod 205a rotatably connected to the center of the rotating chamber 104c, a gear 205b is fixedly installed in the middle of the rotating rod 205a, and the bottom end of the gear 205b is meshingly connected with a tooth plate 205c, one end of the tooth plate 205c passes through the through groove 104b and extends to the stretching groove 104a and is fixedly connected with a stretching plate 205d, the front end of the stretching plate 205d extends to the outside of the fixed plate 104 and is fixedly connected with a handle 205e, the outer surfaces of the front and rear sides of the rotating rod 205a are provided with curved grooves 205f, and the insides of the two groups of curved grooves 205f are slidably connected with driving blocks 205g, the outer sides of the two driving blocks 205g are fixedly installed with moving rings 205h, and the moving rings 205h are slidably sleeved on the outer surface of the rotating rod 205a, and the bottom ends of the two moving rings 205h are fixedly connected with toggle plates 205i.

[0043] In the toggle assembly 205, the rotating rod 205a is suspended in the rotating cavity 104c, and the front and rear ends of the rotating rod 205a are rotatably connected to the inner wall of the fixed plate 104 through the rotating shaft 205j. Therefore, the rotating shaft 205j can play a role of limiting support for the rotating rod 205a, and at the same time, it will not affect the normal rotation of the rotating rod 205a. The gear 205b set in the middle of the rotating rod 205a is meshed and connected with the tooth plate 205c below it, and one end of the tooth plate 205c is connected to the handle 205e set on the outside of the fixed plate 104 through the stretching plate 205d. Therefore, after the staff pulls the handle 205e, the tooth plate 205c can be driven by the stretching plate 205d to move horizontally, and the tooth plate 205c can drive the gear 205b and the rotating rod 205a to rotate.

[0044] It should also be noted that the curved grooves 205f on the front and rear sides of the rotating rod 205a are both arc-shaped, and each curved groove 205f extends along the length direction of the rotating rod 205a, but the curved grooves 205f on both sides have opposite rotation directions. The curved groove on the left is clockwise, and the curved groove on the right is counterclockwise. The groove of each curved groove 205f is arc-shaped, forming a smooth curve along the surface of the rotating rod 205a. This design enables the two driving blocks 205g to drive the two moving rings 205h and the toggle plate 205i to achieve relative horizontal movement when the rotating rod 205a rotates.

[0045] It should be noted that linear grooves 104d are symmetrically provided on the front and rear sides of the bottom of the rotating cavity 104c, and the bottom ends of the two toggle plates 205i respectively penetrate the two linear grooves 104d and extend into the two moving grooves 201b, and the bottom ends of the two toggle plates 205i are respectively arranged on the outsides of the two moving plates 204. The function of the linear grooves 104d is to ensure that the toggle plates 205i can only move in a linear manner to prevent them from deviating during the movement. At the same time, since the top of the toggle plates 205i is fixedly connected to the moving ring 205h, the design of the linear grooves 104d can also prevent the moving ring 205 h is driven by the driving block 205g to make rotational motion. This design ensures that when the rotating rod 205a rotates, the driving block 205g, the moving ring 205h and the toggle plate 205i can only move horizontally and linearly, and the bottom ends of the two toggle plates 205i are respectively arranged on the outsides of the two moving rods 204, so that when the two toggle plates 205i move horizontally relative to each other, they can drive the two moving plates 204 to move horizontally relative to each other, and the two moving plates 204 can drive the two blocking blocks 203 to move into the telescopic groove 201a, thereby releasing the limiting fixation of the docking plate 201 and the fixed plate 102.

[0046] Preferably, the two rotating shafts 205j are rotatably connected to the inner wall of the fixed plate 104 through bearings. The set bearings can limit and fix the rotating shafts 205j. At the same time, due to the characteristics of the bearings themselves, the rotating shafts 205j can rotate more smoothly to avoid jamming and affect the normal operation of the toggle assembly 205.

[0047] Preferably, the opposite sides of the two stretching plates 205d are fixedly connected with stretching springs 205k, and the other ends of the two stretching springs 205k are respectively fixedly connected to the inner walls on the left and right sides of the stretching groove 104a. Through the provision of the stretching springs 205k, when the staff pulls the handle 205e, the stretching plate 205d can also drive the stretching spring 205k to expand, so that when the staff releases the handle 205, the stretching plate 205d and other components in the toggle assembly 205 such as the handle 205e can be reset under the action of the rebound force of the stretching spring 205k, providing the necessary conditions for subsequent use.

[0048] In summary, the working principle of this device is:

[0049] When disassembling, the staff first squeezes the two handles 205e at the top of the fixed plate 104, and the handles 205e drive the toothed plate 205c to move horizontally through the stretching plate 205d, and the toothed plate 205c drives the gear 205b to rotate, and the gear 205b drives the rotating rod 205a to rotate. The two sides of the rotating rod 205a are provided with curved grooves 205f with opposite rotation directions, and the two driving blocks 205g move along the two groups of curved grooves 205f, and the two driving blocks 205g drive the two groups of moving rings 205h and the toggle plate 205i to move horizontally relative to each other, and at the bottom of the rotating cavity 104c Under the guidance of the linear groove 104d at the end, the two toggle plates 205i can only make linear movements, and the bottom ends of the two toggle plates 205i can push the two moving plates 204 to move relatively horizontally, and the two moving plates 204 can drive the two clamping blocks 203 to move inside the telescopic groove 201a, and after the clamping parts a1 of the two clamping blocks 203 are completely moved out of the clamping groove 102b, the limit fixation of the docking plate 201 and the fixed block 102 is released. At this time, the staff can pull the handle 205e upwards to remove the cover plate 103 from the bridge seat 101;

[0050] During installation, the staff aligns the two docking plates 201 at the bottom of the cover plate 103 with the docking groove 102a at the top of the fixed block 102, and presses the cover plate 103 vertically. The card blocks 203 on the front and rear sides of the docking plate 201 are first squeezed into the telescopic groove 201a along the arc surface of the docking groove 102a. When the docking plate 201 is fully inserted into the docking groove 102a, the rebound force of the telescopic spring 202 pops the card block 203 out of the telescopic groove 201a, and the card connection part a1 is inserted into the card groove 102b, so as to fix the docking plate 201 and the fixed block 102. Finally, the cover plate 103 and the bridge seat 101 are firmly fixed and installed.
