Example 3
Referring to fig. 1 to 5, the difference between this embodiment and the previous embodiment is that the first engaging member 101 is further provided with a side hole 101e and a boss 101f, and the side hole 101e is disposed on the side surface of the first engaging member 101 and is communicated with the limiting groove 101 c;
the bosses 101f are arranged on two sides of the side hole 101 e; the stopper 302 is in the side hole 101 e.
The locking piece 301 comprises a connecting shaft 301a, a rotating plate 301b and a hook 301c, the hook 301c is arranged at the end part of the rotating plate 301b, the connecting shaft 301a is arranged on the rotating plate 301b, and the connecting shaft 301a is connected with the boss 101 f;
the rotation plate 301b is in the side hole 101 e.
The rotating plate 301b can rotate around the connecting shaft 301a, and in the rotating process of the rotating plate 301b, the rotating plate 301b can rotate into the limiting groove 101c at the side where the non-clamping hook 301c is located;
it should be noted that the connecting shaft 301a is further provided with a torsion spring, the torsion spring is connected to the boss 101f, and the torsion spring tends to make the end of the hook 301c on the rotating plate 301b away from the side hole 101e, i.e. tends to make the end of the non-hook 301c in the limiting groove 101c, as shown in the position of fig. 3.
The second connecting rod 102a is provided with a square groove 102a-1, the square groove 102a-1 is positioned corresponding to the side hole 101e, and the stop block 302 is arranged in the square groove 102 a-1.
The square groove 102a-1 limits the stop 302 so that the stop 302 is limited to move only along the straight line in the square groove 102 a-1.
A second spring 102a-2 is arranged in the square groove 102a-1, and one end of the second spring 102a-2 is connected with the stop block 302.
The stop 302 is provided with a slope 302a, the slope 302a is arranged at the end of the stop 302, and when the second spring 102a-2 is in a natural state, the slope 302a on the stop 302 is positioned in the side hole 101e and faces the connecting shaft 210 a.
In summary, when the device needs to be installed, the first clamping member 101 and the second clamping member 102 are pressed together, the first spring 103 is compressed, and the first baffle 101b and the second baffle 102b are placed between the first upright a and the second upright b.
In the process of pressing the first clamping piece 101 and the second clamping piece 102, according to the change of 5, the limiting block 102c moves in the limiting groove 101c to compress the first spring 103, and simultaneously touches one end of the rotating plate 301b to enable the rotating plate 301b to rotate until the clamping hook 301c contacts the inclined plane 302a, and because the limiting block 102c always supports against one end of the rotating plate 301b in the moving process, the clamping hook 301c supports against the inclined plane 302a to support the stop block 302 into the square groove 102a-1 along the inclined plane 302a, and the second spring 102a-2 is compressed; when the hook 301c passes over the stop block 302, the stop block 302 moves outwards under the action of the second spring 102a-2 to contact the rotating plate 301b, the force applied to the first clamping member 101 and the second clamping member 102 is removed, the first clamping member 101 and the second clamping member 102 tend to separate towards two sides under the action of the first spring 103, and the first clamping member 101 and the second clamping member 102 keep the state because the hook 301c contacts the stop block 302 and is blocked by the stop block and cannot move away in the separation process.
The rubber layers arranged in the first baffle 101b and the second baffle 102b provide fault tolerance for the distance size between the hook 301c and the stop 302, and since the hook 301c is clamped with the stop 302, the first upright post a needs to be arranged in the first baffle 101b, and the second upright post b needs to be arranged in the second baffle 102b, if no rubber layer exists, the clamping is difficult, and the specific analysis is as follows:
if the hook 301c is engaged with the stop block 302 in one step, the distance between the first barrier 101b and the second barrier 102b is smaller than the distance between the first pillar a and the second pillar b, that is, although the reinforcing component 300 connects the first clip 101 and the second clip 102 together, the whole protection component 100 and the press switch cannot be fixed together;
if the first baffle 101b and the second baffle 102b are contacted with the first upright post a and the second upright post b in one step, the hook 301c cannot be clamped with the stop block 302, and the first clamping piece 101 and the second clamping piece 102 are balanced only by the first spring 103 and are not firm enough;
therefore, it is necessary that the hooks 301c engage with the stoppers 302 while the first shutter 101b and the second shutter 102b contact the first pillar a and the second pillar b.
With the rubber layer, the first baffle 101b and the second baffle 102b can be contacted with the first upright a and the second upright b in one step, and at this time, due to the elasticity of the rubber layer, the first baffle 101b and the second baffle 102b can move a little distance to both sides, so as to provide a space for the hook 301c to be clamped and stopped by the stop block 302.
The stopper 302 is also provided with a pressing shaft 302 b.
The pressing shaft 302b is used for detaching the protective component 100, when the protective component needs to be detached, the pressing shaft 302b is pressed, the stop block 302 enters the square groove 102a-1, the hook 301c is not obstructed by the stop block 302 at the moment, the first clamping piece 101 and the second clamping piece 102 are pulled towards two sides, the first clamping piece 101 and the second clamping piece 102 can be pulled towards two sides due to the fact that a rubber layer is arranged, and the first clamping piece 101 and the second clamping piece 102 cannot be pulled if no rubber layer is arranged.
That is, by pressing the stop block 302 into the square groove 102a-1, the positions of the first clamping member 101 and the second connecting member 102 can be changed, and the protection assembly 100 can be detached by moving.
It should be noted that, the pushing force of the first spring 103 itself to the two sides of the first clamping member 101 and the second clamping member 102 is enough to make them contact and butt with the press switch, and the locking assembly 300 controls the distance between the first clamping member 101 and the first clamping member 102 within a certain range to reduce the force applied to the upright post to prevent deformation.
