[0034] Please refer to Fig. 1 to Fig. 7, the utility model embodiment provides a smaller volume axle body structure, including a base 1 and setting in the base 1 a shell 2, still including setting between shell 2 and base 1 a light guide column 3, the base 1 one side is inwards shell 2 and gives way, the shell 2 upper end is provided with for the upper end of the light guide column 3 one upper insertion slot 21 and is inserted, the shell 2 lower end is located in the position of the base 1 inwards and gives way and forms with the upper insertion slot 21 and is inserted for the lower end of the light guide column 3 one lower insertion slot 22;The light guide column 3 is T-shaped as a whole, and its upper end is a horizontal part 31 inserted into the upper insertion slot 21 and pressed on the upper side wall of the shell 2, and its lower end is a vertical part 32 inserted into the lower insertion slot 22, and the diameter of the horizontal part 31 is greater than that of the lower insertion slot 22.
[0035] By setting the base 1 to one side inwards shell 2 and giving way, the space between the base 1 and the shell 2 is saved to form the lower insertion slot 22, the horizontal part 31 of the light guide column 3 is inserted into the upper insertion slot 21, and the vertical part 32 is inserted into the lower insertion slot 22, so that the light guide column 3 is installed in the shell 2 and the base 1, without the need for additional space on the base 1 to accommodate the light guide column 3, and avoiding the overall height from being raised to accommodate the light guide column 3, so that the overall height can be reduced, the entire axle body structure can be thinner, in addition to realizing multi-angle light guiding, it can also meet the demand of people for thin axle body, improve the use experience of people. After the shell 2 and the base 1 are buckled, the light guide column 3 can be directly inserted into the shell 2 and the base 1 from above, which is beneficial to assembly and effectively improves production efficiency. Furthermore, the diameter of the horizontal part 31 is greater than that of the lower insertion slot 22, so that the horizontal part 31 is inserted into the lower insertion slot 22, the bottom end of the horizontal part 31 is pressed on the side wall of the shell 2, and cannot fall into the lower insertion slot 22, so as to limit the light guide column 3 and prevent it from falling out of the lower insertion slot 22.
[0036] To prevent the problem of falling off the light guide column 3 shell 2, as shown in Figures 2 to 3 and 5 to 7, the longitudinal portion 32 is formed with at least one first lower limit block 321 outwardly protruding from one end away from the base 1, and the shell 2 is formed with a first lower limit slot 23 extending from the lower to the upper wall of the lower insertion slot 22. The top end of the first lower limit slot 23 does not extend out of the shell 2, that is, the first lower limit slot 23 is not completely through the inner wall of the shell 2. After the light guide column 3 is inserted into the upper end of the shell 2, the first lower limit block 321 on it slides from the inner wall of the shell 2 into the first lower limit slot 23 and is limited by the first lower limit slot 23, so that it is pressed against the upper end face of the first lower limit slot 23 and cannot continue to move upward, effectively preventing the problem of falling off the light guide column 3 shell 2.
[0037] Preferably, as shown in Figures 2 to 3 and 5 to 7, the first lower limit block 321 is formed with a first inclined guide slope 3211 extending from the outer upper direction to the inner lower direction, and when the first lower limit block 321 is installed, the first inclined guide slope 3211 first contacts the inner wall of the shell 2. Under the inclined guiding action of the first inclined guide slope 3211, the first lower limit block 321 is more easily inserted into the first lower limit slot 23 by sliding upward on the inner wall of the shell 2 into the first lower limit slot 23, thereby achieving the purpose of limiting and improving the accuracy and efficiency of installation.
[0038] Preferably, as shown in Figures 2 to 3 and 5 to 7, the inner wall of the shell 2 is formed with a shell inner wall inclined surface 26 extending from the outer upper direction to the inner upper direction, and when the first inclined guide slope 3211 of the first lower limit block 321 first contacts the shell inner wall inclined surface 26, the first inclined guide slope 3211 and the shell inner wall inclined surface 26 are guided by each other to make the first lower limit block 321 more easily inserted into the first lower limit slot 23 by sliding upward on the inner wall of the shell 2 into the first lower limit slot 23, thereby achieving the purpose of limiting and improving the accuracy and efficiency of installation.
[0039] To make the light guide column 3 more stable in the lower insertion slot 22, as shown in Figures 2 to 3 and 5 to 7, the shell 2 is formed with a plurality of outer interference pressing blocks 25 protruding inwardly and extending from the inner upper direction to the outer lower direction, and the longitudinal portion 32 moves downward along the outer interference pressing blocks 25 when inserted into the lower insertion slot 22. Due to the structure of the outer interference pressing blocks 25 extending from the inner upper direction to the outer lower direction, the downward pressure of the outer interference pressing blocks 25 gradually increases, and cooperates with the limiting action of the first lower limit block 321, thereby achieving the purpose of stable limiting of the light guide column 3 in the lower insertion slot 22.
[0040] In order to make the light guide column 3 further stable in the lower insertion groove 22, as shown in Figures 4-5 and 7, at least one inner interference pressing block 11 is formed on the outer wall of the base 1 towards the direction of the lower insertion groove 22, protruding towards the direction of the light guide column 3. When the longitudinal portion 32 is inserted into the lower insertion groove 22, it is pressed against the inner interference pressing block 11, and is extruded by the inner interference pressing block 11, so that the light guide column 3 is further stable in the lower insertion groove 22, ensuring the normal operation of the shaft body.
[0041] Preferably, as shown in Figures 4-5 and 7, the upper end of the inner interference pressing block 11 is formed with an inner interference guide surface 111 extending obliquely from the inner upper side to the outer lower side. When the longitudinal portion 32 is inserted into the lower insertion groove 22, the lower end surface of the longitudinal portion 32 first contacts the inner interference guide surface 111. Under the oblique guiding action of the inner interference guide surface 111, the longitudinal portion 32 is more easily moved towards the center of the lower insertion groove 22, so that the longitudinal portion 32 is more accurately and efficiently installed on the shell 2 and the base 1.
[0042] For other structures in the shaft body, such as the guide core, spring, etc., they are conventional technical means in the art, and their principles and structures are prior art, so they are not described in detail in the embodiments.
[0043] Preferably, as shown in Figures 2 and 5, in order to further save the space of the shaft body, the inner side of the light guide column 3 is formed with a guide core accommodation groove matching the guide core on the shaft body. By setting the guide core accommodation groove, the guide core is accommodated, so that the structure in the shaft body is more compact, the space in the shaft body is saved, the overall shaft body structure can be lighter and thinner, the multi-angle light guide can be realized, the demand of people for light and thin shaft body can be met, and the use experience of people is improved.
[0044] Preferably, as shown in Figures 2-3 and 5-7, the lower end outer wall of the longitudinal portion 32 is formed with a light guide inclined surface 323 extending obliquely from the outer upper side to the inner lower side. By setting the light guide inclined surface 323, when the light guide column 3 is inserted, the light guide inclined surface 323 first contacts the inner side wall of the shell 2. Under the guiding action of the light guide inclined surface 323, the longitudinal portion 32 is more easily inserted into the lower insertion groove 22, improving the accuracy and efficiency of installation.
[0045] Embodiment Two
[0046] In the first embodiment, the shaft body structure is described. In this embodiment, the differences from other embodiments are mainly described, and the same structures are not described again in this embodiment.
[0047] As shown in FIGS. 8-11, the main difference between the second embodiment and the first embodiment is that at least one second lower limiting block 322 is formed on each side of the longitudinal portion 32 in the second embodiment, and the housing 2 is formed with a second lower limiting groove 24 extending from the lower end to the upper end of the housing 2 and for accommodating the second lower limiting block 322 at the position of the lower end of the inner wall of the lower insertion groove 22. The top end of the second lower limiting groove 24 does not extend out of the inner wall of the housing 2, that is, the second lower limiting groove 24 is not completely through the inner wall of the housing 2. After the light guide column 3 is inserted into the upper end of the housing 2, the second lower limiting block 322 on the light guide column 3 slides from the inner wall of the housing 2 into the second lower limiting groove 24 and is limited by the second lower limiting groove 24, so as to be pressed against the upper end surface of the second lower limiting groove 24 and cannot continue to move upward, thereby effectively preventing the light guide column 3 from falling out of the housing 2.
[0048] Preferably, as shown in FIGS. 8-11, the outer side of the lower end of the second lower limiting block 322 is formed with a second inclined guide slope 3221 extending from the outer upper end to the inner lower end. When the second lower limiting block 322 is installed, the second inclined guide slope 3221 first contacts the inner wall of the housing 2, and under the inclined guiding action of the second inclined guide slope 3221, the second lower limiting block 322 is more easily inserted into the upper end of the housing 2 and slides into the second lower limiting groove 24, thereby achieving the purpose of limiting and improving the accuracy and efficiency of installation.
[0049] It should be noted that the smaller volume shaft structure disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The guide core, spring and other components involved in the utility model can be general standard components or components known to those skilled in the art, and the structure, principle and control method are known to those skilled in the art through technical manuals or through conventional experimental methods.
