Description

Technical Field

[0001] This utility model relates to the technical field of clothes dryers, specifically to the connecting rivets for the rotor of a clothes dryer. Background Technology

[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate and dry the moisture in washed clothes. It is especially needed in northern winters and in the humid "return to spring" weather in the south where clothes are difficult to dry. In addition, clothes dryers are widely used in industrial production to dry fabrics and improve production efficiency. The clothes dryer generally refers to the simple household type, which is mainly composed of a stand, main unit and outer cover. Its characteristics are moderate price, simple and easy to use, low failure rate, and suitable for ordinary families, students or migrant groups. The clothes dryer uses a rotor to rotate the drying drum, and the connection between the rotor and the drum requires the use of rivets. Therefore, there is an urgent need for rivets to connect the rotor of the clothes dryer.

[0003] Currently, dryer rotors are connected with rivets. When the rotor is connected to the drum, there are no fixing measures at both ends, which can easily cause the drum to fall off. In addition, when the rotor and drum are riveted, the sealing at the riveting point is not good, and moisture inside the dryer may leak into the rotor, affecting normal operation. Utility Model Content

[0004] The purpose of this utility model is to provide a dryer rotor connecting rivet to solve the problems mentioned in the background art. Currently, when using dryer rotor connecting rivets, there are no fixing measures at both ends when connecting the rotor and the drum, which can easily cause the drum to fall off. Furthermore, when the rotor and the drum are riveted, the sealing at the riveting point is not good, and moisture inside the dryer may leak into the rotor, affecting normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dryer rotor connecting rivet, comprising a rivet body and a riveting mechanism, wherein an installation rod is provided at the top of the rivet body, and a first fixing sleeve is installed at the top of the installation rod; the riveting mechanism is installed at the top of the outer wall of the rivet body, and the riveting mechanism comprises a riveting sleeve, a riveting drum, and a retaining plate; the riveting sleeve is provided at the top of the outer wall of the rivet body, the surface of the riveting sleeve is provided with a riveting drum, and a retaining plate is provided at the bottom of the riveting sleeve; a fixing rod is provided at the bottom of the rivet body, and a second fixing sleeve is installed at the bottom of the fixing rod; and a fixing cover is provided at the top of the second fixing sleeve.

[0006] Preferably, the first fixing sleeve and the second fixing sleeve are provided in a one-to-one correspondence, and the first fixing sleeve and the second fixing sleeve are the same size.

[0007] Preferably, the inner wall of the rivet sleeve is in close contact with the outer wall of the rivet body, and the inner wall size of the rivet sleeve matches the outer wall size of the rivet body.

[0008] Preferably, the fixing cover and the rivet body are connected by a thread, and the inner wall of the fixing cover and the outer wall of the fixing rod are both threaded.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The rotor of this dryer is connected by rivets. Through the riveting mechanism, when the rotor of the dryer is riveted to the drum by a riveting machine, the axial force is used to compress and deform the riveting sleeve itself. The multiple riveting drums on the outside of the riveting sleeve deform and fit together, which can effectively prevent the leakage of liquid, gas and other media, and achieve a sealing effect. This prevents water from the dryer drum from entering the rotor and affecting the normal operation of the dryer. In addition, this riveting method has good tensile strength, thereby improving the tightness of the riveting joint.

[0011] 2. The dryer rotor is connected by rivets. The installation rod, first fixing sleeve, fixing rod and second fixing sleeve are set to facilitate the fixed installation of the dryer roller and the fixing rod during riveting. After the riveting is completed, the first fixing sleeve and the installation rod at the top of the rivet body are rotated and tightened to fix it. Then the second fixing sleeve and the fixing rod at the bottom of the rivet body are rotated and tightened to fix it, which can further improve the connection stability. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a dryer rotor connecting rivet, including a rivet body 1 and a riveting mechanism 4. The top end of the rivet body 1 is provided with an installation rod 2, and the top end of the installation rod 2 is provided with a first fixing sleeve 3. The first fixing sleeve 3 and the second fixing sleeve 6 are arranged in a one-to-one correspondence, and the first fixing sleeve 3 and the second fixing sleeve 6 are the same size. Through the installation rod 2, the first fixing sleeve 3, the fixing rod 5 and the second fixing sleeve 6, it is convenient to fix the dryer roller to the fixing rod 5 during riveting. After the riveting is completed, the first fixing sleeve 3 is rotated and tightened to the installation rod 2 at the top end of the rivet body 1, and then the second fixing sleeve 6 is rotated and tightened to the fixing rod 5 at the bottom end of the rivet body 1, which can further improve the connection stability.

[0018] The riveting mechanism 4 is installed on the top of the outer wall of the rivet body 1. The riveting mechanism 4 includes a riveting sleeve 401, a riveting drum 402, and a retaining plate 403. The riveting sleeve 401 is located on the top of the outer wall of the rivet body 1. The surface of the riveting sleeve 401 is provided with the riveting drum 402, and the bottom end of the riveting sleeve 401 is provided with the retaining plate 403. The inner wall of the riveting sleeve 401 is tightly fitted with the outer wall of the rivet body 1, and the inner wall size of the riveting sleeve 401 matches the outer wall size of the rivet body 1. The bottom end of the rivet body 1 is provided with a fixing rod 5, and the bottom end of the fixing rod 5 is equipped with a second fixing sleeve 6. The top end of the second fixing sleeve 6 is provided with a fixing cover 7. The fixed cover 7 and the rivet body 1 are connected by threads, and the inner wall of the fixed cover 7 and the outer wall of the fixed rod 5 are both threaded. With the riveting mechanism 4, when the rotor and drum of the dryer are riveted by the riveting machine, the axial force is used to compress and deform the riveting sleeve 401 itself, and the multiple riveting drums 402 on the outside of the riveting sleeve 401 deform and fit together, which can effectively prevent the leakage of liquid, gas and other media, achieve a sealing effect, and prevent water in the dryer drum from entering the rotor and affecting the normal operation of the dryer. In addition, this riveting method has good tensile strength, thereby improving the tightness of the riveting joint.

[0019] Working principle: When connecting the rotor and drum of the dryer, the axial force is first used to deform the riveting sleeve 401. Multiple riveting drums 402 on the outside of the riveting sleeve 401 deform and fit together, effectively preventing leakage of liquids, gases, and other media, achieving a sealing effect. This prevents moisture from the dryer drum from entering the rotor and affecting the normal operation of the dryer. Furthermore, this riveting method has good tensile strength, thus improving the tightness of the riveting joint. The installation rod 2, first fixing sleeve 3, fixing rod 5, and second fixing sleeve 6 facilitate the fixing of the dryer drum and fixing rod 5 during riveting. After riveting, the first fixing sleeve 3 is rotated and tightened to the installation rod 2 at the top of the rivet body 1, and then the second fixing sleeve 6 is rotated and tightened to the fixing rod 5 at the bottom of the rivet body 1, further improving the connection stability.
