Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dishwasher accessories, specifically a dishwasher tension spring assembly. Background Technology
[0002] Dishwashers, a common kitchen appliance in modern homes, greatly improve the efficiency and convenience of dishwashing. Among the many components of a dishwasher, the tension spring assembly plays a crucial role in ensuring the stable opening and closing of the dishwasher door.
[0003] Currently, in the prior art, for example, Chinese patent with publication number CN208404474U discloses a dishwasher tension spring. This device stretches the tension spring by pulling a ring hook. The ring hook is mainly formed by bending. During long-term use of the tension spring, the ring hook is subjected to a large force, but the force-bearing area is small. The bending point may break, causing the tension spring assembly to fail, resulting in abnormal opening and closing of the dishwasher door, causing great inconvenience to the user. At the same time, the breakage of the tension spring may also cause other safety problems, such as the sudden loss of tension during the closing process of the door, causing the door to close rapidly, which may pinch the user's fingers. In view of this, a dishwasher tension spring assembly is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a dishwasher tension spring assembly that can solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides a dishwasher tension spring assembly, comprising a mounting plate one and a mounting plate two. The mounting plate one is provided with a fixing component for fixing the tension spring. Two sets of fixing components are provided, located at both ends of the tension spring. A connecting rope is fixedly connected to the side of the mounting plate two away from the fixing components, and a pull ring is fixedly connected to the end of the connecting rope away from the mounting plate two. The fixing component includes:
[0006] A connecting plate, on the outer wall of which a fixing disc is fixedly connected;
[0007] A limiting component is disposed on the side of the fixed plate away from the connecting plate;
[0008] The handle is rotatably connected to the connecting plate.
[0009] Preferably, a set of connecting plates near the first mounting plate is hinged to the first mounting plate, and the first mounting plate can be fixedly installed on the inner wall of the dishwasher by bolts.
[0010] Preferably, the set of connecting plates near the second mounting plate is connected to the second mounting plate by bolts. In this way, the fixing components and the tension spring can be disassembled, which facilitates the replacement of the tension spring after its elasticity fails.
[0011] Preferably, the limiting component includes a bidirectional screw, a threaded block is threadedly connected to the outer wall of the bidirectional screw, a hinge rod is hinged to the outer wall of the threaded block, an arc-shaped plate is hinged to the end of the hinge rod away from the threaded block, and an assembly spiral groove is formed on the outer wall of the arc-shaped plate.
[0012] Preferably, the bidirectional screw is rotatably connected to the fixed plate and fixed to the handle. The tension spring is matched with the mounting spiral groove. By rotating the handle, the bidirectional screw rotates, thereby driving the two sets of threaded blocks to move, causing the hinge rod to move, which in turn drives the multiple sets of arc plates to open or close. After the multiple sets of arc plates open, the tension spring is engaged in the mounting spiral groove. In this way, the tension spring has a large force-bearing area when stretched, reducing the possibility of breakage at both ends. After the multiple sets of arc plates close, the tension spring can be easily removed and replaced.
[0013] Preferably, a sliding block is fixedly connected to the side of the arc-shaped plate near the fixed disk.
[0014] Preferably, a groove is provided on the outer wall of the fixed disk, and the sliding block is slidably connected in the groove.
[0015] This utility model provides a dishwasher tension spring assembly. It has the following beneficial effects:
[0016] (1) The dishwasher tension spring assembly uses a fixed component. By turning the handle, the bidirectional screw can drive the threaded block to move, and the hinge rod can drive the arc plate to open. The tension spring is installed in the assembly spiral groove of the arc plate, which increases the force area when the tension spring is stretched. Compared with the traditional bending ring hook, it effectively reduces the breakage of the two ends of the tension spring, extends the service life of the tension spring, and ensures the stable opening and closing of the dishwasher door.
[0017] (2) The dishwasher tension spring assembly allows the fixing component and tension spring to be removed through the use of mounting plate one and mounting plate two. At the same time, with the use of the fixing component, the hinge rod can drive the arc plate to retract, making it easy to remove the tension spring and replace it. When the tension spring loses its elasticity, it can be replaced quickly, reducing maintenance costs and improving maintenance efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-4 This utility model proposes a dishwasher tension spring assembly, including a mounting plate 1 and a mounting plate 4. The mounting plate 1 is provided with a fixing component 2 for fixing the tension spring 3. There are two sets of fixing components 2, and the two sets of fixing components 2 are located at both ends of the tension spring 3. A connecting rope 5 is fixedly connected to the side of the mounting plate 4 away from the fixing component 2, and a pull ring 6 is fixedly connected to the end of the connecting rope 5 away from the mounting plate 4.
[0028] In this embodiment of the utility model, in order to fix the tension spring 3, the fixing component 2 specifically includes a connecting plate 21, a limiting component 23, and a handle 24. A fixing plate 22 is fixedly connected to the outer wall of the connecting plate 21. The limiting component 23 is located on the side of the fixing plate 22 away from the connecting plate 21. The handle 24 is rotatably connected to the connecting plate 21. The limiting component 23 includes a bidirectional screw 231. A threaded block 232 is threadedly connected to the outer wall of the bidirectional screw 231. A hinge rod 233 is hinged to the outer wall of the threaded block 232. An arc-shaped plate 234 is hinged to the end of the hinge rod 233 away from the threaded block 232. An assembly spiral groove 235 is formed on the outer wall of the arc-shaped plate 234. Rod 231 is rotatably connected to fixed plate 22, bidirectional screw 231 is fixed to handle 24, and tension spring 3 is matched with assembly spiral groove 235. By rotating handle 24, bidirectional screw 231 is rotated, which in turn drives two sets of threaded blocks 232 to move, causing hinge rod 233 to move, which drives multiple sets of arc plates 234 to open or close. After the multiple sets of arc plates 234 are opened, tension spring 3 is engaged in assembly spiral groove 325 to fix tension spring 3. In this way, when tension spring 3 is stretched, the force-bearing area of tension spring 3 is increased. Compared with traditional bending ring hooks, it effectively reduces the possibility of breakage at both ends of tension spring 3, extends the service life of tension spring 3, and ensures stable opening and closing of dishwasher door.
[0029] Furthermore, a sliding block 2341 is fixedly connected to the side of the arc plate 234 near the fixed disk 22. A groove 221 is provided on the outer wall of the fixed disk 22, and the sliding block 2341 is slidably connected in the groove 221. The groove 221 limits and guides the sliding block 2341, ensuring the stability of the arc plate 234 when it moves.
[0030] Furthermore, a set of connecting plates 21 near mounting plate 1 are hinged to mounting plate 1. Mounting plate 1 can be fixed to the inner wall of the dishwasher by bolts. A set of connecting plates 21 near mounting plate 4 are connected to mounting plate 4 by bolts. In this way, the tension spring 3 and the fixing component 2 can be removed. Then, by the contraction movement of the arc plate 234, the fixing of the tension spring 3 can be released, and the tension spring 3 can be replaced. When the elasticity of the tension spring 3 fails, it can be quickly replaced, reducing maintenance costs and improving maintenance efficiency.
[0031] In use, rotating the handle 24 causes the bidirectional screw 231 to rotate, which in turn moves the two sets of threaded blocks 232, causing the hinge rod 233 to move. This, in turn, causes the multiple sets of arc plates 234 to open or close. After the multiple sets of arc plates 234 open, the tension spring 3 is engaged in the mounting spiral groove 325, thus fixing the tension spring 3. Then, the mounting plate 1 is installed on the inner wall of the dishwasher to complete the installation of the device. When it is necessary to replace the tension spring 3, the bolts between the mounting plate 1 and the mounting plate 2 are removed, the tension spring 3 and the fixing assembly 2 are taken off, and then the handle 24 is rotated to rotate the bidirectional screw 231, causing the arc plates 234 to close, thus releasing the fixation of the tension spring 3, and the tension spring 3 can be replaced.
[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
