Description
Technical Field
[0001] The utility model relates to the technical field of cable fixing structures, in particular to a wire passing aperture adjustment structure, an air conditioner with the wire passing aperture adjustment structure, and a household appliance with the wire passing aperture adjustment structure. Background Art
[0002] When the same type of air conditioner is used in different countries and regions, the total thickness of the air conditioner's electrical cables may be different due to different wire diameters of the power supply cables, different communication methods, or different numbers of indoor units. In order to accommodate cables of different thicknesses, the wire holes on the air conditioner casing are designed according to the maximum wire diameter of the cable. When using cables with smaller wire diameters, a gap is formed between the inner wall of the wire hole and the cable, causing water and dust to enter the product through the gap, and some smaller insects can also enter the product through the gap, seriously affecting the product's operating safety.
[0003] In order to adapt to cables with different wire diameters and ensure the working safety of the product, there is an existing wire fixing device. A first wire fixing plate and a second wire fixing plate that can be close to and away from each other are arranged between the first support and the second support. A first guide rod is arranged on the side opposite to the first wire fixing plate and the first support. One end of the first guide rod is fixed to the first wire fixing plate, and the other end is slidably arranged on the first support. A first spring is sleeved on the first guide rod, and one end of the first spring is connected to the first support, and the other end is connected to the first fixing plate. A second guide rod is arranged on the side opposite to the second wire fixing plate and the second support. One end is fixed on the second wire fixing plate, and the other end can be slidably inserted into the second support. A second spring is sleeved on the second guide rod, and one end of the second spring is connected to the second support, and the other end is connected to the second fixed plate. A first notch is formed on the side of the first wire fixing plate facing the second wire fixing plate, and a second notch is formed on the side of the second wire fixing plate facing the first wire fixing plate. When the opposite sides of the first wire fixing plate and the second wire fixing plate are abutted together, the first notch and the second notch form a wire passing channel, so that under the elastic action of the first spring and the second spring, the wire passing channel can fix and adapt cables of different wire diameters.
[0004] However, the existing wire fixing device is composed of a plurality of parts such as a first support, a second support, a first wire fixing plate, a second wire fixing plate, a first spring and a second spring. The number of parts is large, and the production and assembly process is complicated, which greatly increases the production cost. In addition, due to the elastic fatigue of the spring, after fixing and adapting the larger wire diameter cable, the compressed spring is difficult to completely reset. When replacing and installing a smaller wire diameter cable, it is easy to form a gap between the smaller wire diameter cable and the wire passage, thereby affecting the reliability of the assembly and further affecting the working safety of the product.

[0009] When a cable with a smaller wire diameter is fixedly installed, the cable is passed through the wire passing channel formed by the baffle and the through hole of the wire passing aperture adjustment structure of the utility model. Since the buckle is arranged at the free end of the elastic arm, the elastic arm has elastic deformation ability, so that the buckle can be disengaged from the positioning groove to unlock the slide of the adjusting member, and then the slide is moved toward the wire passing channel in the aperture adjustment direction, so that the baffle moves toward the cable to adjust the aperture of the wire passing channel to become smaller to adapt to the cable with a smaller wire diameter. As shown in the figure, the wire passing channel with a smaller aperture can be sealed to adapt to the cable with a smaller wire diameter, thereby preventing foreign objects such as water, dust, and insects from entering the interior of the product.

A through hole 116 is provided on a support wall 111 of the housing 11. The adjustment member 12 comprises a slide plate 121 and a baffle plate 122 connected to each other. The slide plate 121 is movably located on the support wall 111 in the aperture adjustment direction. The baffle plate 122 is located in the through hole 116 and forms a wire-passing channel 13 with the through hole 116. Among them, a plurality of positioning grooves 112 are arranged on one of the support wall 111 and the slide plate 121, an elastic arm 1211 is arranged on the other of the slide plate 121 and the support wall 111, and a plurality of positioning grooves 112 are arranged side by side in the aperture adjustment direction.

[0038] When a cable with a smaller wire diameter is fixedly installed, the cable is passed through the wire-passing channel 13 formed by the baffle 122 and the through hole 116 of the wire-passing aperture adjustment structure 10 of this embodiment. Since the buckle 1212 is arranged at the free end of the elastic arm 1211, the elastic arm 1211 has elastic deformation ability, so that the buckle 1212 can be disengaged from the positioning groove 112 to unlock the slide plate 121 of the adjustment member 12, and then the slide plate 121 is moved toward the wire-passing channel 13 in the aperture adjustment direction, so that the baffle 122 moves toward the cable to adjust the aperture of the wire-passing channel 13 to become smaller to adapt to the cable with a smaller wire diameter, such as Fig.12 As shown, the wire passage 13 with a smaller aperture can be sealed to adapt to cables with smaller wire diameters, thereby preventing foreign objects such as water, dust, and insects from entering the interior of the product. Then the buckle 1212 is hooked into the corresponding positioning groove 112, thereby locking the slide plate 121 of the adjustment member 12 on the support wall 111 of the housing 11, so that the baffle 122 of the adjustment member 12 firmly clamps the cable, thereby ensuring that the wire passage 13 is stably and reliably sealed to adapt to cables with smaller wire diameters.
[0039] When a cable with a larger wire diameter is fixedly installed, since the buckle 1212 is arranged at the free end of the elastic arm 1211, the elastic arm 1211 has elastic deformation ability, so that the buckle 1212 can be disengaged from the positioning groove 112 to unlock the slide plate 121 of the adjustment member 12, and then the slide plate 121 is moved away from the wire passage 13 in the aperture adjustment direction, so that the baffle 122 adjusts the aperture of the wire passage 13 to become larger, such as Fig.13 As shown, the cable with a larger wire diameter is then passed through the wire channel 13 formed by the baffle 122 and the through hole 116 of the wire aperture adjustment structure 10 of this embodiment. The wire channel 13 with an enlarged aperture can be sealed to adapt to the cable with a larger wire diameter, thereby preventing foreign matter such as water, dust, and insects from entering the interior of the product. Then the buckle 1212 is hooked into the corresponding positioning groove 112, thereby locking the slide plate 121 of the adjustment member 12 on the support wall 111 of the casing 11, so that the baffle 122 of the adjustment member 12 firmly clamps the cable, thereby ensuring that the wire channel 13 is stably and reliably sealed to adapt to the cable with a larger wire diameter.
[0040] Compared with the existing wire fixing device which is composed of a plurality of parts such as a first support, a second support, a first wire fixing plate, a second wire fixing plate, a first spring and a second spring, the number of parts is large, and the production and assembly process is complicated, which greatly increases the production cost, the wire aperture adjustment structure 10 of the present embodiment is composed of two parts, a housing 11 and an adjustment member 12, the number of parts is small, the structure is simple, and the assembly between the housing 11 and the adjustment member 12 only requires the clamping joint 115 of the clamping structure to pass through the through slot 1213, the assembly process is simple and convenient, thereby greatly The production cost is reduced, and the wire passing aperture adjustment structure 10 of this embodiment can adjust the size of the wire passing channel 13 by moving the slide plate 121 of the adjustment member 12 in the aperture adjustment direction, so that the wire passing channel 13 can be sealed and adapted to cables of different wire diameters, and the buckle 1212 is hooked into the corresponding positioning groove 112, thereby locking the slide plate 121 of the adjustment member 12 on the supporting wall 111 of the casing 11, so that the baffle 122 of the adjustment member 12 firmly clamps the cable, thereby improving the working stability and reliability, thereby improving the working safety of the product.
[0041] Specifically, in this embodiment, a plurality of bosses 113 are protruding from the support wall 111 or the slide plate 121 . The plurality of bosses 113 are arranged side by side in the aperture adjustment direction, and a positioning groove 112 is formed between two adjacent bosses 113 .
[0042] In order to improve the smoothness of the operation of the buckle 1212 being disengaged from and embedded in the positioning groove 112, in this embodiment, the first side surface of each boss 113 in the aperture adjustment direction is inclined, and the second side surface of each boss 113 in the aperture adjustment direction is inclined. Among them, the first side surface of the boss 113 is opposite to the inclination direction of the second side surface of the boss 113, and the inclination angle β of the first side surface 1131 of the boss 113 close to the wire passage 13 in the aperture adjustment direction is smaller than the inclination angle θ of the second side surface 1132 away from the wire passage 13, so that the first side surface 1131 of the boss 113 close to the wire passage 13 in the aperture adjustment direction has a larger resistance, which can resist the buckle 1212 embedded in the positioning groove 112, so that the baffle 122 can stably seal against the cable in the wire passage 13, avoid the cable opening and rebounding to cause the baffle 122 to loosen, and effectively improve the stability and reliability of the baffle 122 sealing against the cable in the wire passage 13.
[0043] In order to further improve the operational smoothness of the buckle 1212 being disengaged from and inserted into the positioning groove 112, in this embodiment, the first side surface of the buckle 1212 in the aperture adjustment direction is tilted, and the second side surface of the buckle 1212 in the aperture adjustment direction is tilted.
[0044] In order to ensure the accuracy and stability of the movement of the slide plate 121 of the adjusting member 12 relative to the supporting wall 111 of the casing 11 in the aperture adjustment direction, the casing 11 of this embodiment is provided with a limit plate 114, and the limit plate 114 is located on the side of the slide plate 121 away from the supporting wall 111, so as to limit the slide plate 121 of the adjusting member 12 between the limit plate 114 and the supporting wall 111 of the casing 11.
[0045] In order to strengthen the structural strength of the baffle 122, in this embodiment, a reinforcing rib 1221 is provided on the side of the baffle 122 away from the wire passing channel 13, thereby improving the structural strength of the baffle 122, preventing the baffle 122 from deforming due to the rebound of the cable and affecting the sealing, thereby improving the stability and reliability of the baffle 122 sealing against the cable in the wire passing channel 13.
[0046] In order to facilitate the assembly of the housing 11 and the adjusting member 12, the guide rod 117 and the clamping joint 115 of this embodiment are provided with a slot 118, so that the guide rod 117 and the clamping joint 115 are separated into two clamping structures with elastic deformation ability, so that the clamping joint 115 of the clamping structure can be quickly passed through the through slot 1213 for assembly. In order to further facilitate the assembly of the housing 11 and the adjusting member 12, the clamping joint 115 of this embodiment is arranged in an umbrella shape, so that the clamping joint 115 of the clamping structure can be easily passed through the through slot 1213 for assembly.
[0047] Second embodiment of the wire aperture adjustment structure:
[0048] As an explanation of the second embodiment of the wire passing aperture adjustment structure of the present invention, only the differences from the first embodiment of the wire passing aperture adjustment structure are explained below.
[0049] See also Fig.14 In this embodiment, the housing 11 and the adjusting part 12 of the wire-passing aperture adjustment structure 20 are connected by a connecting piece 21 and are integrally injection molded. The wire-passing aperture adjustment structure 20 is a component, which further reduces the number of components and eliminates the assembly process of the wire-passing aperture adjustment structure 20, thereby greatly reducing the production cost. Specifically, the integrally injection-molded housing 11 and the adjusting part 12 are connected by a connecting piece 21. The connecting piece 21 is a mold connection structure. When the parts are injection-molded, the plastic material is injected into the housing 11 cavity through the glue inlet on the housing 11, and then injected into the adjusting part 12 cavity through the connecting piece 21, thereby completing the integral injection molding. The connecting piece 21 connects the housing 11 and the adjusting part 12 for injection molding, which facilitates the warehousing, packaging, and transportation of the parts of the wire-passing aperture adjustment structure 20 and reduces warehouse costs.
