Detailed Description
In order to make the technical scheme of the invention more clear, the invention is further described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the features in the following embodiments and examples may be combined with each other without conflict.
In one embodiment of the present invention, a magnetic ring fixing device is provided, as shown in fig. 1, a magnetic ring fixing device 1 includes a supporting device 10 and a mounting base 20, and the mounting base 20 is fixedly connected to the supporting device 10. The support device 10 is provided with a first support arm 11 and a second support arm 12, and a limit part 13 for limiting the magnetic ring 2 and an accommodating part 14 for accommodating the magnetic ring 2 are formed between the first support arm 11 and the second support arm 12. The accommodating portion 14 is located between the limiting portion 13 and the mounting seat 20. The position-limiting portion 13 has elasticity, so as to provide elastic deformation for the magnetic ring 2 to be inserted into the accommodating portion 14 and fix the magnetic ring 2.
As shown in fig. 2-3, the initial width of the stopper 13 is B1, and the thickness of the magnet ring 2 is B. The magnetic ring fixing device 1 can well limit and fix the magnetic ring 2 with the thickness B less than or equal to B1. Under the action of external force, the magnet of the magnetic ring 2 is clamped into the accommodating part 14 through the limiting part 13, so that the limiting part 13 limits the magnetic ring 2 and plays a role in fixing the magnetic ring. Specifically, in the process of clamping the magnetic ring 2, because the limiting part 13 has elasticity, the limiting part 13 is extruded by the magnetic ring 2 under the action of external force, and the limiting part 13 is elastically deformed under the action of stress to increase the width of the limiting part so that the magnetic ring 2 can pass through and be clamped into the accommodating part 14. When the magnet of the magnetic ring 2 is clamped into the accommodating part 14 through the limiting part 13, the pin withdrawing external force is removed, the force acting on the limiting part 13 disappears, at the moment, the elastic deformation of the limiting part 13 is recovered, the width of the limiting part is recovered to the initial width B1, and the B1 is smaller than or equal to the thickness B of the magnetic ring, so that the limiting part 13 can limit the magnetic ring 2, on one hand, the limiting part 13 can prevent the magnetic ring 2 from further moving towards the accommodating part 14, and on the other hand, the magnet of the magnetic ring 2 can be clamped into the limiting part 13 under the self gravity of the magnetic ring 2 to fix the magnetic ring. Therefore, the magnetic ring fixing device 1 of the present invention can fix the magnetic ring with the thickness greater than or equal to B1, that is, the magnetic ring with the thickness B greater than or equal to the initial width B1 of the limiting portion 13 can be fixed by the magnetic ring fixing device 1, and there is no need to design different fixing devices for the magnetic rings with different thicknesses, so that the versatility of the magnetic ring fixing device 1 is improved.
In order to facilitate the insertion of the magnet ring 2 into the receptacle 14, the magnet ring holder 1 further comprises a guide 15. The guide portion 15 is located at a front end of the stopper portion 13, and guides the insertion of the magnetic ring 2 into the accommodating portion 14.
In one embodiment of the present invention, the first support arm 11 is composed of an arc segment 101 and a straight segment 102, wherein one end of the straight segment 102 is connected to the arc segment 101, and the other end thereof is connected to the mounting seat 20. The upper part of the arc-shaped section 101 of the first support arm 11 and the part of the second support arm 12 opposite thereto form a guide part 15, and the middle part of the arc-shaped section 101 of the first support arm 11 and the part of the second support arm 12 opposite thereto form a limit part. The space between the lower portion of the arc-shaped section 101 of the first support arm 11 and the straight section 102 thereof, the portion of the second support arm 12 opposite thereto, and the mount 20 forms the accommodating portion 14.
Further, the second support arm 12 and the first support arm 11 have the same structure, and the second support arm 12 and the first support arm 11 are installed on the installation base 20 in mirror symmetry, and the arc-shaped sections of the two support arms form a "hyperbolic" structure. The narrowest part of the hyperbolic structure is set as the limiting part 13, so that the magnetic ring with the thickness less than or equal to the initial width B1 of the limiting part 13 can be well limited and fixed, and the fixing reliability of the magnetic ring is ensured.
The portions of the first support arm 11 and the second support arm 12 forming the position-limiting portion 13 are made of an elastic material, so that the position-limiting portion 13 has elasticity to provide elastic deformation from which the magnetic ring 2 is snapped into the accommodating portion 14 and fixed to the magnetic ring 2. Preferably, the first support arm 11 and the second support arm 12 are made of elastic materials by integral molding respectively, so that the whole support arm has elasticity, and the support arm has the advantages of simple structure and easiness in implementation.
Preferably, the width B2 of the guide portion 15 satisfies B2 > B, which facilitates guiding the magnetic ring 2 to align with the stopper portion 13, so as to facilitate insertion of the magnetic ring 2 into the accommodating portion 14.
In order to make the magnetic ring fixing device 1 compatible with magnetic rings with different outer diameters, a vertical distance H between the limiting part 13 and the mounting seat 14 is set to satisfy H is larger than or equal to D-D, wherein D is the outer diameter of the magnetic ring, and D is the inner diameter of the magnetic ring, so that the accommodating part 14 can accommodate magnetic rings with different outer diameters.
In order to fix the magnetic ring fixing device 1 to other components, the mounting base 20 further includes a positioning portion 22, and the positioning portion 22 can be inserted into the positioning groove 41 of other components for positioning and fixing the magnetic ring fixing device 1.
Preferably, a buckle 21 for connecting with other components is disposed on an end surface of the positioning portion 22, and as shown in fig. 4, the buckle 21 includes an elastic arm 21a disposed on the positioning portion 22 and extending along an insertion direction of the positioning portion 22, and an upwardly protruding hook 21b disposed on the elastic arm 21 a. Thus, when the positioning portion 22 is inserted into the positioning slot 41, the hook portion 21b is engaged with the slot in the positioning slot 41, so that the positioning portion 22 is fixed in the positioning slot 41. The magnetic ring fixing device adopts a buckle fixing mode, and compared with a screw fixing mode, the magnetic ring fixing device achieves the purposes of convenience and quickness in operation on the premise of meeting the reliability.
In order to smoothly insert the positioning portion 22 into the positioning groove 41, a guide groove 23 extending along the insertion direction of the positioning portion 22 is provided on the end surface of the positioning portion 22, and the buckle 21 is provided at the bottom of the guide groove 23.
Preferably, an upward protruding rib 24 extending along the insertion direction of the positioning portion 22 is disposed on the end surface of the positioning portion 22, and the rib 24 can avoid the shaking caused by the excessively large gap between the positioning portion 22 and the positioning groove 41. Further, the front end of the rib 24 in the insertion direction of the positioning portion 22 is wedge-shaped, so that the positioning portion 22 can be inserted conveniently.
In another embodiment of the invention, the mounting is part of the other component, i.e. the support device 10 is mounted directly on the other component. As shown in fig. 5, the support device 10 is directly fixed to the component 30, and the magnetic ring 2 is fixed by the support device 10. The support device 10 and the member 30 may be fixed by welding, or the support device 10 and the member 30 may be integrally formed. The arrangement has the advantages of simple structure and easy realization.
Therefore, the magnetic ring fixing device can be compatible with magnetic rings with different sizes, different magnetic ring fixing devices do not need to be designed for the magnetic rings with different sizes, the problem that the magnetic rings fixed by wire binding are easy to shake can be avoided, the magnetic rings with different thicknesses and different outer diameters can be reliably fixed by the same magnetic ring fixing device, and the magnetic ring fixing device is quick and convenient to assemble.
In another embodiment of the present invention, an outdoor unit for an air conditioner includes a casing and an electrical box 40 disposed in the casing. As shown in fig. 6 to 7, the electrical box 40 is provided with a positioning groove 41, a guide protrusion 42 and a slot (not shown).
During assembly, firstly, the magnetic ring 2 is arranged in the magnetic ring fixing device 1 to form a magnetic ring assembly, and then the magnetic ring assembly is assembled in the electrical box 40, and the specific process is as follows: the positioning part 22 of the magnetic ring fixing device 1 is inserted into the positioning groove 41 of the electrical appliance box 40 in alignment, in the inserting process, the guide protrusion 42 is matched with the guide groove 23 to play a guiding role, and after the positioning part 22 is inserted into the positioning groove 41, the hook part 21b of the buckle 21 is clamped into the clamping groove, so that the positioning part 22 is firmly fixed in the positioning groove 41; at this time, the rib 24 contacts with the groove wall of the positioning groove 41, and the positioning portion 22 is prevented from wobbling in the positioning groove 41. If the magnetic ring assembly needs to be disassembled, a certain acting force is applied to the buckle 21 of the magnetic ring fixing device 1, and then the whole magnetic ring assembly can be disassembled.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention.
