[0002] In daily life, a wall breaker and a soymilk maker are common electrical appliances. Inside the wall breaker and the soymilk maker, a coupler is an important electrical component. The coupler is usually assembled by combining an upper coupler and a lower coupler.

[0003] For example, a lower coupler with an air avoidance space with the publication number of CN210111130U includes a lower coupler main body, a lower coupler assembly body and a plug spring. The lower coupler assembly body can be clamped in the lower coupler main body, and a downward extending connecting part is arranged on it. There is an air avoidance space between the lower side of the downward extending connecting part and the lower side of the lower coupler main body; the plug spring can be clamped on the lower coupler assembly body, and its lower end is located in the air avoidance space.

[0004] Among the above-mentioned existing technologies, there are the following technical problems: the bottom of the existing coupler does not have a corresponding shock absorption structure during use, so that after the coupler is used inside home appliances with strong vibration during the operation of a wall breaker or a soymilk maker, etc., it is easy to cause looseness and falling off inside the coupler due to strong vibration. At the same time, when the lower coupler is assembled with the upper coupler, it is not easy to effectively ensure the stability of the connection between the two, so that after being affected by an external force, the lower coupler and the upper coupler are prone to fall off.

[0005] Therefore, we propose a lower coupler with an air avoidance space to solve the problems raised above. Content of the Utility Model

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Example 1: Please refer to Figures 1 - 3 When the existing lower coupler is installed, a corresponding air-avoiding space is set inside the housing, which causes the plug spring inside the lower coupler to be easily deformed and damaged after being squeezed by external force. In order to solve this technical problem, this embodiment discloses the following technical contents:

[0037] A lower coupler with an avoidance space comprises a lower coupler shell 1, a docking block 2 is fixedly installed on the front and rear sides of the lower coupler shell 1, a lower coupler assembly 3 is installed inside the lower coupler shell 1, a card slot 4 for installing a plug spring is provided on the side of the lower coupler assembly 3, and a card block 7 is installed on the left and right sides of the lower coupler shell 1; an avoidance plate 5 is provided above the card slot 4, and a buffer pad 6 is installed between the avoidance plate 5 and the inside of the lower coupler shell 1; the avoidance plate 5 is set as a rectangular structure, and the avoidance plate 5 is located directly above the card slot 4, and the buffer pad 6 fixedly connected between the avoidance plate 5 and the inside of the lower coupler shell 1 is set to an elastic rubber material.

[0038] When assembling the lower coupler housing 1, insert the spring into the card slot 4 on the side of the lower coupler assembly 3, and then install the lower coupler assembly 3 inside the lower coupler housing 1. At this time, the upper end of the spring presses against the avoidance plate 5 inside the lower coupler housing 1, causing the avoidance plate 5 to move and squeeze the buffer pad 6. The buffer pad 6 is deformed under pressure to form an avoidance space, preventing the spring from directly and rigidly contacting the inside of the lower coupler housing 1 and deforming.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1. In the existing coupler, no corresponding shock-absorbing structure is provided at the bottom, resulting in strong vibration when the coupler is used inside household appliances such as blenders or soy milk makers with strong vibration during operation. It is easy to cause phenomena such as loosening and falling off inside the coupler due to severe vibration. To solve this technical problem, the following technical content is disclosed in this embodiment, as Figure 1 、 Figure 2 and Figure 5 shown;

[0040] The lower end of the lower coupler housing 1 is provided with a support foot 9, and the upper end of the support foot 9 is fixedly connected with a damping rod 10. A locking hole 11 is formed on the support foot 9. The upper end of the damping rod 10 is inserted into the inside of the movable slot 12, and the movable slot 12 is formed inside the side of the lower coupler housing 1. The damping rod 10 is connected to the inside of the movable slot 12 through an internal spring 13. The damping rod 10 can slide inside the movable slot 12.

[0041] A locking hole 11 is formed on the support foot 9. A locking bolt is passed through the locking hole 11 to fix the lower coupler housing 1 in the required position. When the electrical equipment vibrates during operation, the lower coupler housing 1 slides on the damping rod 10 of the support foot 9. After the lower coupler housing 1 moves on the damping rod 10, the elastic deformation of the internal spring 13 can play a role in shock absorption and buffering, preventing the electrical components inside the lower coupler housing 1 from falling off and loosening due to excessive vibration amplitude for a long time.

[0042] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2. When the existing lower coupler is assembled with the upper coupler, it is not easy to effectively ensure the stability of the connection between the two, resulting in the problem that the lower coupler and the upper coupler are prone to falling off under external force. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figure 1 、 Figure 4 、 Figure 6 and Figure 7 shown;

[0043] A positioning mechanism 8 is fixedly connected to the clamping block 7, and the positioning mechanism 8 is used to improve the stability of the connection with the upper coupler housing. The positioning mechanism 8 includes a guide column 801, a contact block 802, an adjustment block 803 and a reset spring 804, and the guide column 801 is fixed to the upper end of the clamping block 7, and the left and right sides of the guide column 801 are fixedly installed with the contact block 802, and the upper part of the contact block 802 is provided with an adjustment block 803, and the adjustment block 803 is inserted into the guide column 801, and the adjustment block 803 is connected to the inside of the guide column 801 through the reset spring 804. The contact block 802 is symmetrically arranged about the vertical central axis of the guide column 801, and the contact block 802 and the adjustment block 803 are parallelly distributed. The outer wall of one end of the adjustment block 803 extending into the inside of the guide column 801 and the inner wall of the guide column 801 are mutually attached, and the adjustment block 803 forms an elastic telescopic structure with the reset spring 804 and the guide column 801. The upper surface of one end of the adjusting block 803 extending out of the guide column 801 is set as a bevel, and the lower surface of one end of the adjusting block 803 extending out of the guide column 801 is set as a horizontal plane.

[0044] When assembling the lower coupler housing 1 and the upper coupler housing, the guide column 801 on the clamping block 7 is passed through the hole on the side of the upper coupler housing. At this time, the hypotenuse of the adjustment block 803 on the side of the guide column 801 is squeezed by the lower edge of the hole. After being pressed, the adjustment block 803 moves toward the inside of the guide column 801, so as to be accommodated in the inside of the guide column 801. When the guide column 801 continues to push, so that the adjustment block 803 accommodated in the guide column 801 moves to the top of the hole on the side of the upper coupler housing, the adjustment block 803 rebounds under the action of the return spring 804, so that the adjustment block 803 extends outward, and its surface is in contact with the top of the hole on the side of the upper coupler housing, and the upper surface of the interference block 802 fixedly connected to the side of the guide column 801 is in contact with the lower surface of the hole on the side of the upper coupler housing, thereby ensuring the stability of the connection between the upper coupler housing and the lower coupler housing 1.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
