Dismantle not fragile electrical apparatus box subassembly, as shown in fig. 1, fig. 2, including base 10, dustcoat 20, base 10 carries out detachable connections with dustcoat 20. As shown in fig. 3, 4 and 5, a laterally protruding hook 21 is disposed on an outer side wall of one end of the outer cover 20, an elastic rotating arm 22 is disposed on the other end of the outer cover 20, and a bayonet 221 is disposed on the elastic rotating arm 22; as shown in fig. 6 and 7, the base 10 is provided with a clamping seat 11 corresponding to the hook 21 of the outer cover 20, the clamping seat 11 is provided with an accommodating cavity 113, and the base 10 is provided with a clamping block 12 corresponding to the bayonet 221 of the elastic rotating arm 22; namely, the hook 21 is matched with the clamping seat 11, the bayonet 221 is matched with the clamping block 12, and the base 10 and the outer cover 20 are detachably connected.
As shown in fig. 8, 9, 10, and 11, when the base 10 is connected to the housing 20, the hook 21 is located in the accommodating cavity 113, the engaging seat 11 limits the hook 21, the latch 12 is located in the latch 221, and the latch 12 limits the latch 221, thereby fixing the housing 20 to the base 10. When the cover 20 is detached, as shown in fig. 12 and 13, the elastic rotating arm 22 is rotated with the connecting position of the elastic rotating arm 22 and the cover 20 as a fulcrum, so that the latch 12 is disengaged from the bayonet 221, the outer side wall of the cover 20 abuts against the end surface of the latch seat 11 facing the cover 20, and the cover 20 is rotated with the latch seat 11 as a fulcrum until the cover 20 is removed at an angle sufficient for removing the cover 20, so that the cover 20 can be removed. During installation, the hook 21 is aligned to the fastening seat 11 and inserted into the accommodating cavity 113 until the outer side wall of the outer cover 20 abuts against the end surface of the fastening seat 11 facing the outer cover 20, and the outer cover 20 is rotated by taking the fastening seat 11 as a fulcrum until the fastening block 12 enters the fastening opening 221. In the installation process, because the elastic rotating arm 22 has a certain elasticity, when the clamping block 12 and the elastic rotating arm 22 are squeezed, the elastic rotating arm 22 is elastically deformed until the clamping block 12 reaches the range of the clamping opening 221, and the elastic rotating arm 22 elastically resets under the action of elastic restoring force due to the loss of the support of the clamping block 12, so that the clamping block 12 enters the clamping opening 221 to form clamping limit.
As shown in fig. 6 and 7, in order to insert the hooks 21 of the outer cover 20 into the accommodating cavities 113 of the clamping seats 11, the clamping seats 11 are protruded from the surface of the base 10, and the clamping seats 11 are higher than the surface of the base 10, so that a sufficient space for the hooks 21 to be inserted is ensured at the positions facing the accommodating cavities 113. Meanwhile, in order to achieve the lossless abutting of the clamping seat 11 and the outer cover 20, the end face of the clamping seat 11 facing the outer cover 20 comprises a vertical supporting face 111 located at the lower part and an abdicating notch 112 located at the upper part, and during the disassembly, the abdicating notch 112 provides an abdicating space for the rotation of the outer cover 20. When the installation targets in place, the lateral wall of dustcoat 20 is parallel with the vertical holding surface 111 of joint seat 11, when dismantling, to elasticity swinging boom 22 application of force, and then drive dustcoat 20 and move towards joint seat 11, until offseting, then vertical holding surface 111 laminates mutually with the lateral wall of dustcoat 20 because parallel, even external force is great, can not cause the pressure of sharp-pointed part too big and cause the lateral wall of dustcoat 20 to appear surface damage. In the rotating process, as shown in fig. 13, the upper portion of the outer cover 20 is inevitably close to the clamping seat 11, and the abdicating notch 112 is provided, so that an abdicating space is provided for the rotation of the outer cover 20, and the smooth rotation of the outer cover 20 is ensured, and in the rotating process of the outer cover 20, the side wall of the outer cover 20 can be prevented from being pushed against and extruded, and the surface damage of the side wall of the outer cover 20 is avoided.
In this embodiment, the relief notch 112 is formed by an inclined surface having an angle not smaller than an angle sufficient for removing the outer cover 20. When the angle of inclined plane is implemented for certain suitable dismouting angle, when dismantling, rotate the lateral wall and the parallel laminating of inclined plane to dustcoat 20 when dustcoat 20, angle that promptly can break away from, and the inclined plane can provide the change on feeling for whether can distinguish easily among the dismantlement process and arrive the dismantlement angle, improve dismantlement efficiency.
In order to reduce the opening height and depth of the accommodating cavity 113, as shown in fig. 4, the lower portion of the end of the hook 21 is set to be an inward-inclined surface 211 or an arc surface, so that the rotation space required by the hook 21 in the rotation process of the outer cover 20 is reduced. Meanwhile, the height and depth of the accommodating cavity 113 of the fastening seat 11 are sufficient to provide a rotating space for the hook 21 during the detachment, so as to ensure that the hook 21 is not pressed during the detachment process, as shown in fig. 13.
In order to easily break the elastic rotating arm 22 and elastically contract the elastic rotating arm 22 until the fixture block 12 is separated from the bayonet 221, the length of the elastic rotating arm 22 needs to be increased to increase the torque and reduce the requirement for the magnitude of the external force. In this embodiment, as shown in fig. 5, the bottom end of the elastic rotating arm 22 is connected to the bottom end of an extending arm 23 disposed on the outer sidewall of the outer cover 20, and the bottom end of the extending arm 23 extends to the lower portion of the outer cover 20. The connecting position of the elastic rotating arm 22 and the outer cover 20 is moved downwards to the lower part of the outer cover 20 through the extension arm 23, so that the length of the elastic rotating arm 22 is lengthened, and the moment is increased.
Further, the extension arm 23 and the elastic rotating arm 22 are smoothly transited through a U-shaped arc surface 24. The U-shaped arc surface 24 makes the elastic rotating arm 22 closer to the clamping block 12, that is, the clamping block 12 just completely enters the range of the clamping opening 221 when the elastic rotating arm 22 is in a vertical state; when the latch 12 is detached, the elastic rotating arm 22 is snapped to a sufficient angle to disengage the latch 12 from the latch opening 221, so that the stroke is shortest and the force is applied least, i.e., the operation is easiest.
In order to improve the strength of the extension arm 23, the extension arm 23 is provided with a plurality of reinforcing ribs 231 along the length direction to prevent the extension arm 23 from being broken.
Since the space of the electric appliance box is limited, it is difficult to provide a sufficient width for fingers to extend in the transverse direction, and in order to ensure the convenience of operation, in the present embodiment, as shown in fig. 11, the height of the part of the base 10 where the latch 12 is provided is lower than the height of the end of the elastic rotation arm 22. Namely, the part of the base 10 provided with the latch 12 does not form a shield on the end of the elastic rotating arm 22 in the transverse direction, which is more beneficial to providing a larger space for fingers to extend into for operation. Further, a position of the elastic rotation arm 22 higher than the base 10 where the latch 12 is provided as the support portion 222 inclined outward. The support portion 222 inclined outward is more favorable for applying force to fingers, and can drive the elastic rotating arm 22 to rotate for a longer distance with smaller force, thereby further improving the convenience of operation.
The above embodiments are merely illustrative, and not restrictive, of the present invention. Changes, modifications, etc. to the above-described embodiments are intended to fall within the scope of the claims of the present invention, as long as they are in accordance with the technical spirit of the present invention.
