The utility model is provided with a card slot, a protection plate body, a card block, a cavity, a pull rod, a tension spring, a placement cavity, a limit rod, a support spring and a limit slot. The pull rod is pulled so that the tension force of the support spring drives the limit rod to reset, and the protection plate body and the mounting plate are engaged with each other through the card block and the card slot to prevent the protection plate body from deviating when being installed with the mounting plate. After loosening the pull rod, the pull rod moves downward by the tension force of the tension spring, so that the pull rod pushes the limit rods on both sides to engage with the limit slots provided inside the mounting plate, thereby achieving the purpose of facilitating the auxiliary positioning and installation of the protection plate body and the mounting plate;

[0017] 2. The existing overspeed protection plate is directly fixed in the machine body by screws, and its circuit board is exposed to the outside, which is easy to accumulate dust. The utility model is provided with a slide groove, a two-way screw rod, a nut seat, a support frame, a hand crank, a through hole, a connecting rod, a fixing frame and a dustproof cloth. When the two-way screw rod is rotated, the two-way screw rod drives the nut seat connected with the external thread to move horizontally, and at the same time, the support frame moves together, so that the dustproof cloth is stretched out, thereby achieving the purpose of protecting the protection plate body by the dustproof cloth.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0023] The following describes an embodiment of the utility model based on its overall structure.

[0024] An overspeed protection plate with an auxiliary positioning structure, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 1, a card slot 2 is symmetrically opened on the top of the mounting plate 1, a protection plate body 3 is snap-connected on the top of the mounting plate 1, a card block 4 is symmetrically welded to the bottom of the protection plate body 3, a cavity 5 is symmetrically opened inside the protection plate body 3, a pull rod 6 that penetrates into the card block 4 is slidably connected inside the cavity 5, a tension spring 7 is welded and connected between the pull rod 6 and the cavity 5, a placement cavity 8 is symmetrically opened on one side of the card block 4 near the pull rod 6, a limit rod 9 is slidably connected inside the placement cavity 8, a support spring 10 is welded and connected between the limit rod 9 and the placement cavity 8, The slot 2 is symmetrically provided with limit slots 11 about the central axis of the block 4. The pull rod 6 is pulled so that the tensile force of the support spring 10 drives the limit rod 9 to reset, and the protection plate body 3 and the mounting plate 1 are engaged with each other through the block 4 and the slot 2 to prevent the protection plate body 3 from being offset when installed with the mounting plate 1. After the pull rod 6 is released, the pull rod 6 moves downward due to the tensile force of the tension spring 7, so that the pull rod 6 pushes the limit rods 9 on both sides to engage with the limit slots 11 opened inside the mounting plate 1, thereby achieving the purpose of facilitating the auxiliary positioning and installation of the protection plate body 3 and the mounting plate 1.

[0025] See also Figure 1 and Figure 2It can be seen that the protection plate body 3 and the mounting plate 1 form a locking structure through the clamping block 4 and the clamping slot 2, the pull rod 6 and the cavity 5 form an elastic structure through the tension spring 7, the limit rod 9 and the placement cavity 8 form an elastic structure through the support spring 10, and the clamping block 4 and the mounting plate 1 form a locking structure through the limit rod 9 and the limit slot 11. When the protection plate body 3 needs to be disassembled and replaced, the pull rod 6 can be pulled so that the tension force of the support spring 10 drives the limit rod 9 to reset, and the limit slot 11 at the mounting plate 1 loses the engagement of the limit rod 9, pulling the protection plate body 3 upward, thereby achieving the purpose of facilitating the quick disassembly of the protection plate body 3.

[0026] See also Figure 1 and Figure 3 It can be seen that the limiting rod 9 and the placement cavity 8 form an elastic structure through the support spring 10, the clamping block 4 and the mounting plate 1 form a clamping structure through the limiting rod 9 and the limiting groove 11, and the mounting plate 1 is symmetrically provided with a slide groove 12 inside. The inside of one slide groove 12 is connected with a two-way screw rod 13 through a bearing, and the inside of the other slide groove 12 is welded with a slide rod, and the outer sleeve of the slide rod is provided with a sliding sleeve, and the top of the sliding sleeve and the nut seat 14 are welded with a support frame 15, the outer thread of the two-way screw rod 13 is connected with the nut seat 14, and the top of the nut seat 14 is welded with the support frame 15, and the support frame 15 and the mounting plate 1 form a sliding structure through the nut seat 14 and the slide groove 12, and one end of the two-way screw rod 13 is welded with a hand crank 16, and the hand crank 1 A through hole 17 is provided inside 6, and a connecting rod 18 extending to the inside of the mounting plate 1 is slidably connected inside the through hole 17.

The dustproof cloth 20 is connected to the support frame 15 by screws. When the bidirectional screw rod 13 is rotated, the bidirectional screw rod 13 drives the nut seat 14 connected with the external thread to move horizontally, and at the same time, the support frame 15 moves together, so that the dustproof cloth 20 is stretched open, thereby achieving the purpose of protecting the protection plate body 3 by the dustproof cloth 20. When maintenance is required, the dustproof cloth 20 is easy to fold and store, which reduces the occupied space and makes it easy to repair the protection plate body 3.

[0027] The working principle of the utility model is as follows: when using the overspeed protection plate with an auxiliary positioning structure, the pull rod 6 is pulled so that the tensile force of the support spring 10 drives the limit rod 9 to reset, and the protection plate body 3 is engaged with the mounting plate 1 through the clamping block 4 and the clamping groove 2 to prevent the protection plate body 3 from being offset when installed with the mounting plate 1. After loosening the pull rod 6, the pull rod 6 moves downward through the tensile force of the tension spring 7, so that the pull rod 6 pushes the limit rods 9 on both sides to engage with the limit grooves 11 opened inside the mounting plate 1, thereby achieving the purpose of facilitating the auxiliary positioning and installation of the protection plate body 3 and the mounting plate 1. When the bidirectional screw rod 13 is rotated, the bidirectional screw rod 13 drives the nut seat 14 with the external thread connection to move horizontally, and at the same time moves the support frame 15 together, so that the dustproof cloth 20 is stretched open, thereby achieving the purpose of protecting the protection plate body 3 with the dustproof cloth 20.
