[0020] As Figures 1-5 shown, a connection structure of a seat armrest in a preferred embodiment of the present utility model includes a connection sleeve 1, a mounting plate 2, and a support tube 3. The connection sleeve 1 includes a base 11 and an upper shell 12. One side of the base 11 is provided with a connection through groove 111, and the connection through groove 111 communicates with the inside of the connection sleeve 1. Generally, the connection through groove 111 cooperates with the mounting plate 2. The top of the connection through groove 111 is open. The upper shell 12 is covered on the base 11. The top of the upper shell 12 is provided with a connection hole 121, and the connection hole 121 communicates with the inside of the connection sleeve 1. Generally, the connection hole 121 cooperates with the support tube 3. The side part of the upper shell 12 is provided with a cover plate 122 covering the top of the connection through groove 111. One end of the mounting plate 2 passes through the connection through groove 111 and extends into the connection sleeve 1. The bottom end of the support tube 3 passes through the connection hole 121 and extends into the connection sleeve 1, and is fixedly connected to the end of the mounting plate 2. Generally, the mounting plate 2 is horizontally arranged, and the support tube 3 is vertically fixed on the mounting plate 2. The support tube 3 is welded to the mounting plate 2, and the connection is firm.
[0021] The assembly process of this embodiment is as follows: First, fix the bottom end of the support tube 3 on one end of the mounting plate 2; then place the end of the mounting plate 2 connected to the support tube 3 on the base 11, and the mounting plate 2 cooperates with the connection through groove 111. At this time, the end of the mounting plate 2 far from the support tube 3 extends out of the connection through groove 111; then sleeved the upper shell 12 onto the support tube 3 from the top end of the support tube 3, specifically, set the upper shell 12 at the top end of the support tube 3 and make the top end of the support tube 3 pass through the connection hole 121; finally, adjust the positions of the upper shell 12 and the base 11 so that their positions correspond, and then assemble and fix the upper shell 12 and the base 11, so that the support tube 3, the mounting plate 2, and the mounting plate 2 are connected into one body, and the assembly is simple; the setting of the connection sleeve 1 plays a role in wrapping the connection part of the support tube 3 and the mounting plate 2. On the one hand, it can play a role in shielding to avoid the exposure of the connection part of the support tube 3 and the mounting plate 2 and affect the overall beauty. On the other hand, it can play a role in protection to prevent the connection part of the support tube 3 and the mounting plate 2 from being damaged and affecting the connection stability of the two.
[0022] Exemplarily, a plurality of first card slots 112 are arranged along the outer periphery of the base 11. A plurality of first snap blocks 123 corresponding to the first card slots 112 one by one are arranged on the inner side of the upper shell 12. The first snap blocks 123 are snapped into the first card slots 112. A second card slot 113 is arranged on the inner side of the connecting through groove 111. The cover plate 122 is provided with a second snap block 124 that is snapped into the second card slot 113. The base 11 and the upper shell 12 are connected by snap connection, without using connecting parts such as bolts, and the assembly is simple and the structure is firm.
[0023] Exemplarily, a first guiding surface that gradually inclines inward from bottom to top is arranged at the bottom of the first snap block 123, and a second guiding surface that gradually inclines outward from top to bottom is arranged at the bottom of the second snap block 124. During assembly, when the position of the upper shell 12 corresponds to the position of the base 11, the upper shell 12 is pressed down. At this time, the first guiding surface and the second guiding surface play a guiding role, facilitating the first snap block 123 to be snapped into the first card slot 112 and facilitating the second snap block 124 to be snapped into the second card slot 113, and the assembly is simple.
[0024] Exemplarily, a third card slot 21 is arranged at the bottom of the mounting plate 2. A connecting column 114 is arranged in the base 11. A third snap block 115 that is snapped onto the third card slot 21 is arranged at the top of the connecting column 114. During assembly, the mounting plate 2 is placed on the base 11, so that the mounting plate 2 cooperates with the connecting through groove 111, and at the same time, the third snap block 115 is snapped onto the third card slot 21, so that the base 11 and the mounting plate 2 are fixed together, preventing the mounting plate 2 from shifting during subsequent assembly and facilitating the subsequent assembly connection between the base 11 and the upper shell 12.
[0025] Exemplarily, positioning columns 125 are arranged at the bottom of the upper shell 12, and positioning grooves 116 that cooperate with the positioning columns 125 are arranged on the base 11, which helps with the positioning connection between the upper shell 12 and the base 11.
[0026] Exemplarily, reinforcing ribs 126 are arranged on the inner side wall of the upper shell 12, which helps to improve the structural strength of the upper shell 12.
[0027] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
