[0033] Referring to Figures 1-7 The present application embodiment provides an inner handle swing angle limiting device, which can effectively limit the rotation of the handle, thereby avoiding the handle from colliding with the shell 10 and causing damage to the shell 10, and affecting the appearance of the shell 10. In order to achieve the above technical purpose, the inner handle swing angle limiting device comprises a shell 10 and a handle 20, and the specific structure is introduced as follows:
[0034] The shell 10 is the outer shell of an electrical appliance. The side of the shell 10 is provided with a protrusion 30. The number of protrusions 30 can be two, and they are respectively located on the two sides of the shell 10. The protrusion 30 is provided with a first limiting portion (which can be a notch groove 31); the first limiting portion is used to limit the swing angle of the handle 20.
[0035] Further, the end of the handle piece 20 is provided with a handle hole 21, and specifically, the handle piece 20 can be U-shaped, and both ends thereof are provided with the handle hole 21. The inner side of the handle hole 21 is provided with a second limiting part (which can be specifically a limiting block 211); the protrusion 30 is embedded in the handle hole 21, the handle piece 20 can rotate around the protrusion 30; and the first limiting part and the second limiting part limit each other to limit the rotation angle of the handle piece 20, so as to avoid the handle piece 20 from colliding with the shell 10. Understandably, at the rotation limit position of the handle piece 20, there is also a safe anti-collision distance between the handle piece 20 and the shell 10, so that the handle piece 20 can be prevented from colliding with the shell 10.
[0036] In the technical scheme of the utility model embodiment, the built-in handle swing angle limiting device comprises a shell 10 and a handle piece 20; the side of the shell 10 is provided with a protrusion 30, and the protrusion 30 is provided with a first limiting part; the end of the handle piece 20 is provided with a handle hole 21, and the inner side of the handle hole 21 is provided with a second limiting part; the protrusion 30 is embedded in the handle hole 21, and the first limiting part and the second limiting part limit each other to limit the rotation angle of the handle piece 20, so as to avoid the handle piece 20 from colliding with the shell 10. It can be seen that, by the mutual limiting of the first limiting part and the second limiting part, the rotation angle of the handle piece 20 can be limited, so that, at the rotation limit position of the handle piece 20, there is also a safe anti-collision distance between the handle piece 20 and the shell 10, so that the handle piece 20 can be prevented from colliding with the shell 10.
[0037] Further, in some embodiments, for example in the embodiment, the first limiting part is a notch groove 31 opened on the protrusion 30.
[0038] Correspondingly, the second limiting part is a limiting block 211 protruding from the inner side of the handle hole 21, the limiting block 211 is embedded in the notch groove 31, the limiting block 211 can rotate in the notch groove 31 and is limited by the side wall of the notch groove 31.
[0039] Specifically, the width of the notch groove 31 is greater than the width of the limiting block 211, so that the limiting block 211 can rotate in the notch groove 31 together with the handle piece 20, and when the limiting block 211 rotates to the side wall of the notch groove 31, it is limited by the side wall.
[0040] Further, in some embodiments, for example in the embodiment, in order to improve the uniformity of the force borne by the limiting block 211, the shapes of the protrusion 30 and the notch groove 31 are both fan-shaped, and the two side walls of the notch groove 31 are arranged along the radial direction of the protrusion 30.
[0041] Specifically, the notch groove 31 is also a sector shape. The central angle of the notch groove 31 can be determined by those skilled in the art according to the required limiting angle, which is not specifically limited in the utility model, for example, it can be 30-180°.
[0042] Correspondingly, the diameter of the handle hole 21 matches the diameter of the protrusion 30, and the two side walls of the limiting block 211 are arranged along the radial direction of the handle hole 21.
[0043] Specifically, the diameter of the handle hole 21 is the same as the diameter of the protrusion 30, or the diameter of the handle hole 21 is slightly larger than the diameter of the protrusion 30, for example, 5%, so as to facilitate assembly. The two side walls of the limiting block 211 are arranged along the radial direction of the handle hole 21, so that when the limiting block 211 is in contact with the notch groove 31, the limiting block 211 can be completely fitted on the side wall of the notch groove 31, thereby making the stress of the limiting block 211 more uniform, avoiding the breakage of the limiting block 211 due to uneven stress. The limiting block 211 can be integrally formed with the handle piece 20, so that the limiting block 211 has greater strength.
[0044] Further, the built-in handle swing angle limiting device further comprises a clamping and fixing assembly for clamping and fixing the end of the handle piece 20 on the shell 10. Specifically, the clamping and fixing assembly can prevent the handle piece 20 from falling off the shell 10.
[0045] Further, in some embodiments, for example, the clamping and fixing assembly comprises a handle shaft 41 and a fastener 42, the handle shaft 41 comprises a shaft body 411 and a cover body 412 provided at one end of the shaft body 411, the shaft body 411 passes through the handle hole 21 and the shell 10 and is fixed by the fastener 42, and the cover body 412 is clamped at the end of the handle piece 20.
[0046] Specifically, the middle part of the protrusion 30 of the shell 10 is provided with a through hole penetrating the shell 10. The shaft body 411 passes through the handle hole 21 and the through hole in the middle part of the protrusion 30.
[0047] The fastener 42 is specifically a screw, the end of the shaft body 411 is provided with a screw hole, and the fastener 42 is fixed with the screw hole.
[0048] Further, the clamping and fixing assembly further comprises a gasket 44, and the gasket 44 is arranged between the fastener 42 and the shell 10. Specifically, by arranging the gasket 44, the reliability of the connection can be improved.
[0049] Further, the clamping and fixing assembly further comprises a decorative ring cover 43, an inner side of the decorative ring cover 43 is provided with a supporting table 431, and an inner side of the supporting table 431 is provided with a first protruding part 432; one side of the cover body 412 is provided with a second protruding part 413; the handle shaft 41 is embedded in the decorative ring cover 43; the supporting table 431 is in abutment with the cover body 412, so that the cover body 412 is prevented from penetrating through the decorative ring cover 43; and the first protruding part 432 and the second protruding part 413 are limited to each other.
[0050] Specifically, the decorative ring cover 43 is annular, and the decorative ring cover 43 plays a decorative role and can improve the appearance. Meanwhile, the decorative ring cover 43 and the cover body 412 can cover the end of the handle piece 20, thereby leading to a connecting structure and improving the appearance.
[0051] The supporting table 431 can reliably support the handle shaft 41, and the handle shaft 41 is prevented from being separated from the decorative ring cover 43. The handle shaft 41 and the decorative ring cover 43 can be synchronously rotated through the mutual limitation of the first protruding part 432 and the second protruding part 413.
[0052] The number of the first protruding part 432 and the second protruding part 413 is the same, and the number can be multiple, thereby improving the reliability of the limitation.
[0053] The technical effects of the embodiments of the utility model include:
[0054] 1. In the utility model, the handle shaft 41, the shell 10 and the decorative ring cover 43 are injection molded, and the handle piece 20 is stamping formed, so that assembly is simple, and obvious cost advantage is compared with conventional handle structure.
