Detailed implementation manner

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The existing rat guards usually install a whole board on the access door of the equipment room, and the height of the rat guard is fixed. If the height of the rat guard is relatively low, it will affect the rat-blocking effect of the equipment. If the height of the rat guard is relatively high, it will cause inconvenience to the normal entry and exit of maintenance personnel. Especially when transporting medium and large-sized tools, the staff also need to disassemble the rat guard and reinstall it after the transportation is completed. This process is very troublesome and inconvenient for the staff to use.

[0021] To solve the defects existing in the use of the above-mentioned rat guard, please refer to Figures 1-4, a rat guard structure for a signal equipment room provided by the utility model can not only increase the overall height of the rat guard, optimize the protection effect of the rat guard, but also flexibly adjust the height of the rat guard, control the contraction of the rat guard, facilitate the entry and exit of staff, and facilitate the transportation of medium and large-sized instruments. The rat guard is based on a fixed seat 1. A first rat guard 2 is rotatably installed at the top of the fixed seat 1. A second rat guard 3 is slidably arranged on one side of the first rat guard 2. The fixed seat 1 is used to support the equipment. An elevating mechanism 6 for driving the second rat guard 3 to slide up and down is arranged in the first rat guard 2. The height of the second rat guard 3 can be conveniently adjusted freely through the elevating mechanism 6. Among them, a servo motor 61 is fixedly installed inside the elevating groove 5, and the output end of the servo motor 61 is fixedly connected with a threaded rod 62. The threaded rod 62 is rotatably installed inside the elevating groove 5, and a connecting seat 63 is threadedly connected to the outside of the threaded rod 62. The connecting seat 63 is slidably installed between the two inner walls on both sides of the elevating groove 5. The side surface of the second rat guard 3 is fixedly connected with the connecting seat 63. Driving the servo motor 61 can drive the threaded rod 62 to rotate. The rotation of the threaded rod 62 can drive the connecting seat 63 to slide up and down. The up and down sliding of the connecting seat 63 can drive the second rat guard 3 to slide up and down, so as to adjust the height of the second rat guard 3, facilitating the staff to adjust the height of the equipment according to the usage requirements. And when the second rat guard 3 slides up to the top along the first rat guard 2, the overall height of the equipment is much greater than that of the traditional rat guard, which can improve the protection effect of the equipment.

[0022] Due to the relatively high overall height of the equipment, when the staff enters and exits, although the height of the second rat guard 3 can be lowered to the lowest, the height of the first rat guard 2 will still affect the entry of the staff and impede the transportation of the instruments. To solve this technical problem, a flipping mechanism 4 for driving the first rat guard 2 to rotate is provided on both sides of the second rat guard 3. When the second rat guard 3 slides down and contracts to a certain extent, the flipping mechanism 4 can drive the first rat guard 2 to flip, so that the first rat guard 2 and the second rat guard 3 jointly flip downward to facilitate the entry and exit of the staff. Among them, the rotating shaft 45 is rotatably installed on the fixed seat 1. The bottom of the first rat guard 2 is fixedly sleeved outside the rotating shaft 45, and the end of the rotating shaft 45 is fixedly connected with a passive gear 46. A sliding seat 41 is also provided. The sliding seat 41 is fixedly installed at the end of the second rat guard 3, and the sliding seat 41 is slidably connected with the end of the first rat guard 2. Installation grooves 42 are symmetrically opened inside the sliding seat 41. An active toothed plate 44 is slidably installed up and down inside the installation grooves 42. The active toothed plate 44 is adapted to the passive gear 46. An electric telescopic rod 43 is fixedly installed on the inner top wall of the installation groove 42. The telescopic end of the electric telescopic rod 43 is fixedly connected to the upper end of the active toothed plate 44. When the lifting mechanism 6 drives the second rat guard 3 to slide down until the active toothed plate 44 meshes with the passive gear 46, the second rat guard 3 can continue to slide down to drive the passive gear 46 to rotate through the active toothed plate 44. The rotation of the passive gear 46 drives the rotation of the rotating shaft 45, and the rotation of the rotating shaft 45 drives the rotation of the first rat guard 2, realizing that the second rat guard 3 drives the first rat guard 2 to flip downward while sliding down, so that the first rat guard 2 flips to be parallel to the ground, facilitating the passage of the staff.

[0023] It should be noted that the equipment is equipped with an entrance and exit wireless switch control. Through the entrance and exit wireless switch control, the servo motor 61 can be driven. Moreover, through the exit wireless switch control, the electric telescopic rod 43 close to the exit can be commanded to contract and the electric telescopic rod 43 far from the exit can be commanded to extend. While the entrance wireless switch control can command the electric telescopic rod 43 close to the entrance to contract and the electric telescopic rod 43 far from the entrance to extend. By controlling the telescopic movement of the corresponding electric telescopic rod 43, the flipping direction of the first rat guard 2 can be controlled. And the entrance and exit wireless switch control can be set in the form of a control panel or a switch button and installed at reasonable positions inside and outside the equipment room according to the actual situation. With such a setting, whether the staff enters or leaves the equipment room, the first rat guard 2 can be flipped in the direction of the staff's advance through the control panel, preventing the first rat guard 2 from pressing on the staff's feet when flipping, and there is no need for the staff to specifically make room for the first rat guard 2 to flip, further facilitating the entry of the staff.

[0024] In order to further facilitate the transportation of instruments to the equipment room, a grounding block 7 is fixedly connected to the upper end of the first rat guard 2, and a transition platform 8 is fixedly connected to the upper end of the second rat guard 3. When the first rat guard 2 is flipped outward towards the equipment room door, the grounding block 7 and the transition platform 8 can contact the ground, providing stable support for the first rat guard 2. Moreover, the transition platform 8 is provided with a slope to facilitate pushing the instruments onto the second rat guard 3, and further facilitate transporting the instruments into the equipment room.

[0025] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
