Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a simple tea bar machine buckle installation structure. Background Art

[0002] There are two main ways to install the backrest of the existing tea bar machine. One is screw installation, which requires users to have certain engineering installation capabilities and special screwdriver tools, and is inconvenient to install; the other is pin and buckle fixing. The disadvantage of the pin is that the pin is easy to fall and cannot be found, and the installation of the pin still requires certain engineering installation capabilities. The buckle does not require many installation skills and can be easily inserted. However, there are some problems with the existing buckle installation on the market. First, the buckle often relies on its own elasticity to achieve buckling, and the number of disassembly times is limited. The buckle is deformed due to multiple disassembly, resulting in a decrease in the amount of engagement and a decrease in the connection effect. It is easy to be too tight or too loose during use, which makes the customer feel poor. In addition, some buckles have many parts, which increases material costs and assembly time.

The seat 113 is fixedly assembled to the cavity 104 by bolts, the back plate 105 is provided with a button slot 107 for the button 115 to extend and retract, and the lower end surface of the backrest 103 is provided with an escape area 106 for the claw 133 to move. The mounting slot 112 is formed on the table 102, and the snap slot 111 is arranged below the table 102 and communicates with the mounting slot 112.

[0037] In this embodiment, the seat body 113 includes a seat body shell 117, a telescopic area 118 formed inside the seat body shell 117, and guide grooves 119 arranged on both sides of the telescopic area 118. The telescopic area 118 is suitable for accommodating the spring 114. The guide groove 119 includes at least one convex ridge 120 arranged along its length. The seat body shell 117 is formed with a limit groove 121 located on the upper side of the telescopic area 118 and a movement area 122 located on the lower side of the telescopic area 118.

[0038] In this embodiment, the button 115 includes a pressable button portion 123, a driving portion 124 and guide rails 125 arranged on both sides of the driving portion 124. The guide rails 125 correspondingly include at least one groove 126 arranged along its length direction. The convex rib 120 slides in cooperation with the groove 126, thereby guiding the driving portion 124 to reciprocate in the telescopic zone 118.

[0040] In this embodiment, the buckle portion 116 is a hook-type cantilever buckle, including a cantilever beam 132 and a claw 133 formed at one end of the cantilever beam 132, the other end of the cantilever beam 132 is integrally formed with the lower surface of the driving portion 124, and the seat shell 117 is formed with the cantilever beam 132 reciprocating in the motion area 122. Specifically, the cantilever beam 132 is arranged perpendicular to the driving portion 124, the claw 133 includes a retaining surface 134 suitable for abutting the card slot 111, and the retaining surface 134 and the cantilever beam 132 are clamped to form a retaining angle of 90°.

[0041] In this embodiment, a first positioning column 135 is provided in the telescopic area 118, and the driving part 124 includes a second positioning column 136. A limiting strip 137 extending along the axial direction thereof is protruded above the second positioning column 136, and the hook portion 127 is provided on the limiting strip 137. The cantilever beam 132 is connected to the second positioning column 136. One end of the spring 114 is engaged with the first positioning column 135 and abuts against the seat shell 117, and the other end of the spring 114 is engaged with the second positioning column 136 and abuts against the convex rib 120 and the cantilever beam 132.

[0042] The process of installing the back plate 105 is as follows: during installation, the user holds both sides of the backrest 103 with both hands and keeps pressing the button 115. At this time, the button part 123 drives the driving part 124 to slide and compress the spring 114. The button 115 is suitable for sliding with the seat body 113 in the horizontal direction, and the barb part 127 moves from the limit end surface 128 to the other end. The button 115 is suitable for driving the buckle part 116 to move synchronously to align with the installation groove 112. Then, the back plate 105 is held and moved downward, so that the plug-in part 108 and the slot 109 are plugged in the vertical direction until the table 102 supports the backrest 103, and the backrest 103 and the cabinet 101 are limited in the horizontal direction. Finally, the external force is removed, and the spring 114 is released to drive the button 115 to reset, and at the same time drive the buckle part 116 to engage with the slot 111, thereby forming a limit between the backrest 103 and the cabinet 101 in the vertical direction, and the hook part 127 is suitable for abutting against the limit slot 121 to limit the separation of the seat body 113 and the button 115, and to keep the buckle part 116 and the slot 111 engaged.
