Description

Technical Field

[0001] This utility model belongs to the field of metal fittings technology, specifically a reinforcing structure for metal fittings of household appliances. Background Technology

[0002] Metal fittings for home appliances are metal parts that constitute the key functions and structural support of various home appliances. They are usually made of materials such as steel, aluminum alloy, or stainless steel, and are manufactured through processes such as stamping, casting, and cutting. Their types include fasteners (such as screws and rivets), support frames (such as TV wall mounts), and decorative parts (such as oven door handles). These fittings are widely used in refrigeration equipment, cleaning appliances, kitchen and bathroom appliances, and environmental appliances, ensuring the mechanical strength and durability of home appliances, and also achieving specific functions such as shock absorption, electrical conductivity, or heat dissipation through precise design.

[0003] Existing TV wall mount brackets, after installation, require tightening two vertical safety screws at the bottom to prevent the TV from being lifted or pushed and falling off. Because the two safety screws are set vertically, they are prone to loosening and falling off if not installed properly or affected by vibration, resulting in poor stability. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a reinforcing structure for metal accessories of home appliances, which effectively solves the problem that existing TV wall mount brackets, after installation, require tightening two vertical safety screws located at the bottom for security. Because the two safety screws are vertically set, they are prone to loosening and falling off when not installed properly or affected by vibration, resulting in poor stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforcing structure for metal fittings of household appliances, including a support plate. Two support bars are provided on the front side of the support plate. A slanted groove is formed on the rear side of the top of the support plate. A locking head is fixedly installed on the upper rear side of each of the two support bars, and both locking heads are engaged within the slanted groove. An installation groove is formed on the upper rear side of the support plate. A limiting block is fixedly installed on one side of each of the two locking heads. A limiting head is engaged on the upper part of each of the two limiting blocks. An elastic limiting component is provided on the lower part of each of the two limiting heads. The elastic limiting component can adjust the limiting distance between the two limiting heads and the two limiting blocks. Connecting holes are formed at the four corners of the support plate, and fixing holes are formed at both ends of each of the two support bars.

[0006] Preferably, two internal threaded seats are fixedly installed on the lower side of the front part of the support plate. The interior of each internal threaded seat is threaded with a long screw. The bottom of each long screw is fixedly installed with a rod head, and the upper end of each long screw is threaded with an internal threaded block. One side of each internal threaded block is fixedly connected to two support bars.

[0007] Preferably, the elastic limiting component includes a rotating shaft disposed at both ends inside the mounting groove. Rotating seats are rotatably mounted at both ends of the two rotating shafts. One side of each of the four rotating seats is fixedly connected to the inside of the mounting groove. A fixing sleeve is fixedly mounted at the middle of the surface of each of the two rotating shafts. Movable arms are fixedly mounted on the surface of each of the two fixing sleeves. The tops of the two movable arms are fixedly connected to the two limiting heads respectively. Torsion springs are sleeved at both ends of the surface of each of the two rotating shafts. The two ends of the four torsion springs are fixedly connected to the four rotating seats and the two ends of the two fixing sleeves respectively.

[0008] Preferably, a transmission rod is rotatably mounted on one side of each movable arm, and a sliding sleeve is rotatably mounted on the lower end of each transmission rod. A sliding rod is inserted inside each sliding sleeve, and the lower ends of both sliding rods are fixedly connected to the inside of the mounting groove through a support arm. A spring is sleeved on the lower end of the surface of each sliding rod, and the two ends of each spring are fixedly connected to the sliding sleeve and the support arm, respectively. A fixing frame is fixedly mounted on the top of each sliding rod, and the lower ends of both fixing frames are fixedly connected to the support arm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator fixes the two support bars to the back of the TV and the support plate to the building wall. Then, together with the TV, the two clips on the two support bars are inserted into the inclined groove for installation. At the same time as the two clips are inserted into the inclined groove, the limiting blocks on the two clips will push the two limiting heads. When the two limiting heads are pushed, they will drive the two fixed sleeves and two rotating shafts to rotate backward along the rotating seat through the two movable arms, and at the same time, the four torsion springs will be twisted.

[0010] As the two movable arms rotate backward, two transmission rods push the two sliding sleeves downward along the surfaces of the two sliding rods. Simultaneously, the downward movement of the sliding sleeves compresses the two springs. When the two limit blocks reach their positions, the elastic force of the four torsion springs drives the two movable arms and two limit heads to rotate and reset via the two fixed sleeves. At the same time, the two springs push the two sliding sleeves upward. As the sliding sleeves move upward, they drive the two movable arms and two limit heads to rotate and reset via the two transmission rods, thus locking the two limit heads onto the two limit blocks for locking and limiting, preventing the TV from slipping upward and enhancing installation stability. Finally, the operator uses two rods to drive two long screws upward along the interior of the two internal thread seats, entering the two internal thread blocks for fixing, further improving installation stability. This allows the TV wall mount bracket to, after installation, secure the two lower vertical safety screws while simultaneously locking and limiting the two upper locking heads, enhancing installation stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 6The present invention includes a support plate 1 connected to a wall. Two support strips 2 are provided on the front side of the support plate 1, and the two support strips 2 are connected to the rear side of the television. A slanted groove 3 is formed on the rear side of the top of the support plate 1. A locking head 4 is fixedly installed on the upper rear side of each of the two support strips 2, and the two locking heads 4 are adapted to the two slanted grooves 3, each locking head being engaged inside the slanted groove 3. An installation groove 5 is formed on the upper rear side of the support plate 1. A limiting block 6 is fixedly installed on one side of each of the two locking heads 4, and a limiting head is engaged on the upper part of each of the two limiting blocks 6. 7. A locking limit is formed between the two limiting blocks 6 and the two limiting heads 7. The lower part of the two limiting heads 7 is provided with an elastic limiting component. The elastic limiting component can adjust the limit between the two limiting heads 7 and the two limiting blocks 6. The four corners of the support plate 1 are provided with connecting holes 23. The support plate 1 can be fixed to the building wall by the cooperation of four expansion bolts and four connecting holes 23. The two ends of the two support bars 2 are provided with fixing holes 24. The two support bars 1 can be fixed to the TV section by the cooperation of four bolts and four fixing holes 24.

[0022] During use, the operator fixes the two support bars 2 to the back of the TV and the support plate 1 to the building wall. Then, together with the TV, the two clips 4 on the two support bars 2 are inserted into the inclined groove 3 for installation. At the same time as the two clips 4 are inserted into the inclined groove 3, the limiting blocks 6 on the two clips 4 will push the elastic limiting component to operate, so that the elastic limiting component drives the two limiting heads 7 to engage with the two limiting blocks 6 for locking and limiting, thereby preventing the TV from slipping and increasing the stability of the installation.

[0023] Two internal threaded seats 19 are fixedly installed on the lower front side of the support plate 1. The interior of each internal threaded seat 19 is threaded with a long screw 21. The bottom of each long screw 21 is fixedly installed with a rod head 22, and the upper end of each long screw 21 is threaded with an internal threaded block 20. The two long screws 21 can be screwed into the middle of the two internal threaded blocks 20 to form a threaded fixation. One side of each of the two internal threaded blocks 20 is fixedly connected to two support bars 2.

[0024] The operator uses two rod heads 22 to drive two long screws 21 to rotate upwards along the inside of two internal thread seats 19 and enter two internal thread blocks 20 for fixation, thereby improving the stability of the installation.

[0025] The elastic limiting assembly includes rotating shafts 8 disposed at both ends inside the mounting groove 5. Rotating seats 9 are rotatably mounted at both ends of the two rotating shafts 8, allowing the two rotating shafts 8 to rotate around the rotating seats 9 as the center. One side of each of the four rotating seats 9 is fixedly connected to the inside of the mounting groove 5. Fixed sleeves 10 are fixedly mounted on the middle of the surface of each of the two rotating shafts 8. Movable arms 12 are fixedly mounted on the surface of each of the two fixed sleeves 10. The tops of the two movable arms 12 are fixedly connected to the two limiting heads 7 respectively. Torsion springs 11 are sleeved on both ends of the surface of each of the two rotating shafts 8. The two ends of the four torsion springs 11 are fixedly connected to the four rotating seats 9 and the two ends of the two fixed sleeves 10 respectively. The torsion springs 11 have the ability to elastically return to their original position.

[0026] While the two clamps 4 are clamped into the inclined groove 3, the limiting blocks 6 on the two clamps 4 will push the two limiting heads 7. When the two limiting heads 7 are pushed, they will drive the two fixed sleeves 10 and the two rotating shafts 8 to rotate backward along the rotating seat 9 through the two movable arms 12, and at the same time, they will twist the four torsion springs 11.

[0027] A transmission rod 13 is rotatably mounted on one side of each movable arm 12. A sliding sleeve 14 is rotatably mounted on the lower end of each transmission rod 13. A sliding rod 15 is inserted inside each sliding sleeve 14. The two sliding sleeves 14 can move along the surfaces of the two sliding rods 15. The lower ends of the two sliding rods 15 are fixedly connected to the interior of the mounting groove 5 through a support arm 16. A spring 17 is sleeved on the lower end of the surface of each sliding rod 15. The two ends of the two springs 17 are fixedly connected to the sliding sleeve 14 and the support arm 16, respectively. The two springs 17 have the ability to elastically return to their original position. A fixing bracket 18 is fixedly mounted on the top of each sliding rod 15. The lower ends of the two fixing brackets 18 are fixedly connected to the support arm 16. The two fixing brackets 18 can improve the vertical stability of the two sliding rods 15.

[0028] When the two movable arms 12 rotate backward, the two transmission rods 13 push the two sliding sleeves 14 to move down along the surface of the two sliding rods 15. As the two sliding sleeves 14 move down, they will squeeze the two springs 17. When the two limit blocks 6 move down to their positions, under the elastic force of the four torsion springs 11, they will be driven by the two fixed sleeves 10 to rotate and reset the two movable arms 12 and the two limit heads 7.

[0029] Simultaneously, the two springs 17 push the two sliding sleeves 14 upward. When the two sliding sleeves 14 move upward, they will push the two movable arms 12 and the two limit heads 7 to rotate and reset through the two transmission rods 13, thereby locking the two limit heads 7 onto the two limit blocks 6 for locking and limiting, thus preventing the TV from slipping upward and enhancing the stability of the installation. After the TV wall mount bracket is installed, tightening the two vertical safety screws 21 at the bottom for safety can also lock and limit the two clips 4 at the top, thereby enhancing the stability of the installation.
