Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning appliance technology, and in particular relates to a combined floor brush connector structure. Background Technology
[0002] Vacuum cleaners are widely used in daily life. The working principle of a vacuum cleaner is that an electric motor drives blades to rotate at high speed, creating negative air pressure within a sealed casing, which sucks in dust and debris. The floor brush is an essential component of a vacuum cleaner. Currently, commonly used vacuum cleaner floor brushes include a brush head and a brush bend. One end of the brush bend connects to the brush head via a universal joint, and the other end connects to the suction hose. The suction hose connects the brush bend to the brush head via a suction hose. However, the brush bend and the universal joint are connected by a snap-fit mechanism. With increased use, the contact points between the snap-fit mechanism and the universal joint are prone to wear, causing the brush bend to loosen, affecting the normal use of the floor brush and reducing the user experience. Utility Model Content
[0003] The purpose of this utility model is to provide a combined floor brush connector structure to solve the problem of loosening between the floor brush bend and the universal joint.
[0004] To achieve the above objectives, this utility model provides a combined floor brush connector structure, which includes:
[0005] A floor brush bend, wherein the upper and lower sides of the floor brush bend are respectively provided with first mounting grooves;
[0006] The fastener is disposed in the first mounting groove and passes through the floor brush bend and is rotatably connected to the universal joint;
[0007] The universal joint has slots on both sides of the end away from the floor brush bend, and a second mounting groove is provided on the bottom of the inner side of the universal joint.
[0008] An elastic limiting block is inserted into the second mounting groove. The elastic limiting block is hooked to the corresponding slots through the first hooks on both sides. The elastic limiting block abuts against the fastener.
[0009] As a further description of the above technical solution:
[0010] The second mounting groove is provided with a protrusion, and the two second hooks on the buckle are hooked onto the protrusion, and the second hooks are movably connected to the protrusion.
[0011] As a further description of the above technical solution:
[0012] There is a first gap between one end of the protrusion and the top of the second mounting groove, and a first baffle is provided at the other end of the protrusion. There is a second gap between the first baffle and the bottom of the second mounting groove. The second baffle at one end of the elastic limiting block abuts against the top of the second mounting groove, and the third baffle at the other end of the elastic limiting block abuts against the first baffle.
[0013] As a further description of the above technical solution:
[0014] The universal joint has a rotating shaft on each side, and the universal joint is rotatably connected to the floor brush head through the rotating shaft.
[0015] As a further description of the above technical solution:
[0016] A retaining ring is provided at one end of the rotating shaft, and a clamping component is provided below the retaining ring. The clamping component is located on the brush head.
[0017] As a further description of the above technical solution:
[0018] The clamping assembly includes a spring and a clamping block. One end of the spring is connected to the brush head, and the other end of the spring is connected to the clamping block. The clamping block abuts against the retaining ring.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the floor brush connector is composed of a floor brush bend, a snap fastener, a universal joint, and an elastic limiting block. The floor brush bend and the universal joint are rotatably connected by two snap fasteners. The elastic limiting block is located on the lower side of the universal joint. After the elastic limiting block is inserted into the second mounting groove, it is hooked onto the groove by two first hooks, which can achieve the effect of easy disassembly and assembly. The first baffle, the second baffle, and the third baffle can restrict the up and down movement of the elastic limiting block, so that the elastic limiting block always abuts against the snap fastener. After the snap fastener is worn, the elastic limiting block can also make the snap fastener stably connect the floor brush bend and the universal joint without loosening. Attached Figure Description

[0034] Please see Figure 1-6 This utility model provides a combined floor brush connector structure, which includes:
[0035] Floor brush bend 1, wherein the upper and lower sides of the floor brush bend 1 are respectively provided with first mounting grooves 2;
[0036] The fastener 3 is disposed in the first mounting groove 2 and passes through the floor brush bend 1 and is rotatably connected to the universal joint 4.
[0037] The universal joint 4 has slots 5 on both sides of the end away from the floor brush bend 1, and a second mounting groove 6 is provided on the bottom of the inner side of the universal joint 4.
[0038] The elastic limiting block 7 is inserted into the second mounting groove 6. The elastic limiting block 7 is hooked to the corresponding groove 5 by the first hooks 8 on both sides. The elastic limiting block 7 abuts against the buckle 3.
[0039] A protrusion 9 is provided in the second mounting groove 6, and two second hooks on the fastener 3 are hooked onto the protrusion 9, with the second hooks movably connected to the protrusion 9. This increases the thickness of the universal joint at the fastener, thereby increasing its strength.
[0040] One end of the protrusion 9 has a first gap with the top of the second mounting groove 6, and the other end of the protrusion is provided with a first baffle 10. The first baffle 10 has a second gap with the bottom of the second mounting groove 6. The second baffle 11 at one end of the elastic limiting block 7 abuts against the top of the second mounting groove 6, and the third baffle 12 at the other end of the elastic limiting block 7 abuts against the first baffle 10. The third baffle is located below the second baffle. The first baffle, the third baffle, and the third baffle cooperate to restrict the up and down movement of the elastic limiting block, so that the elastic limiting block is always in contact with the fastener.
[0041] The universal joint 4 has a rotating shaft 13 on each side, and the universal joint 4 is rotatably connected to the floor brush head 14 via the rotating shaft. A retaining ring 15 is provided at one end of the rotating shaft 13, and a clamping assembly is provided below the retaining ring 15, which is mounted on the floor brush head 14. The clamping assembly includes a spring 16 and a clamping block 17. One end of the spring 16 is connected to the floor brush head 14, and the other end of the spring 16 is connected to the clamping block 17, which abuts against the retaining ring 15. The retaining ring prevents the rotating shaft from detaching from the floor brush head; the spring allows the clamping block to hold the retaining ring in place, thus preventing the universal joint from rotating and facilitating user operation.
[0042] Working principle: The floor brush connector consists of a floor brush bend, snap fasteners, a universal joint, and an elastic limiting block. The floor brush bend and the universal joint are rotatably connected by two snap fasteners. The elastic limiting block is located on the lower side of the universal joint. After the elastic limiting block is inserted into the second mounting groove, it is hooked onto the groove by two first hooks, which can facilitate disassembly and assembly. The first baffle, second baffle, and third baffle can restrict the up and down movement of the elastic limiting block, so that the elastic limiting block always abuts against the snap fasteners. After the snap fasteners wear, the elastic limiting block can also help the snap fasteners to stably connect the floor brush bend and the universal joint without loosening.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
