Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below.
as shown in fig. 1, the present invention provides an embodiment of a rotatable armrest, which includes an armrest body 1 and a rotating shaft 2, wherein a shaft sleeve 11 is disposed at an end portion of the armrest body 1, and with reference to fig. 2, a shaft hole 12 rotatably connected to the rotating shaft 2 is disposed in the shaft sleeve 11; a groove part 13 and a first arc-shaped convex part 14 arranged on the inner wall 111 of the shaft sleeve are also arranged in the shaft sleeve 11; at least one guiding mechanism 3 is detachably fixed on the rotating shaft 2, referring to fig. 3, the guiding mechanism 3 is disposed in the groove portion 13, and the guiding mechanism 3 includes a second arc-shaped protruding portion 31 adapted to the inner wall 111 of the shaft sleeve, and a third arc-shaped protruding portion 32 adapted to the first arc-shaped protruding portion 14.
Referring to fig. 4, during the rotation of the armrest in one direction, when the first arc-shaped protrusion 14 contacts with one side of the third arc-shaped protrusion 32, the armrest rotates to a limit position; accordingly, when the first arc-shaped protrusion 14 contacts the other side of the third arc-shaped protrusion 32 during the rotation of the armrest in the other direction, the armrest rotates to reach the other limit position, thereby realizing the rotation of the armrest in a certain angle. The axle sleeve inner wall 111 is located to first arc convex part 14 that this embodiment played the positioning action, and the atress ability is strong, and is difficult for impairedly, and second arc convex part 31 and third arc convex part 32 of guiding mechanism 3 respectively with axle sleeve inner wall 111 and first arc convex part 14 looks adaptation, and the direction is effectual, and handrail body 1 can keep at two extreme positions.
In order to fix the armrest on the seat conveniently, one end of the rotating shaft 2 is provided with a connecting part 21. When the handrail rotates, the rotating parts are only the handrail body 1 and the shaft sleeve 11, the connecting part 21, the rotating shaft 2 and the guiding mechanism 3 do not rotate, and in order to fix the rotating shaft 2, the guiding mechanism 3 and the connecting part 21, the side wall of the rotating shaft 2 comprises at least one plane, namely, the side surface of the rotating shaft 2 can be the combination of an arc surface and the plane, or can be all planes; in addition, the guiding mechanism 3 is provided with a first mounting hole 33 matched with the rotating shaft 2, the connecting part 21 is provided with a second mounting hole 211 matched with the end part of the rotating shaft 2, and the connecting part 21 is sleeved on the end part of the rotating shaft 2. The connecting part 21, the rotating shaft 2 and the guide mechanism 3 of the embodiment are assembled, relative fixation is realized without using parts such as screws, and the assembly is simple and convenient; and the guide mechanism 3 can be detached from one side of the rotating shaft 2, so that the replacement is convenient.
Because the rotatable armrest is in a common state, namely, in a deployed state and a stowed state, the sum of the arcs of the first arc-shaped convex portion 14 and the second arc-shaped convex portion 31 is preferably set to 270 °, that is, the turning angle of the armrest body 1 ranges from 0 to 90 °, and the armrest body 1 can be turned 90 ° from one limit position (i.e., in the deployed/stowed state) to be converted into the other limit position (i.e., in the stowed/deployed state). The better guiding effect is realized, the first arc-shaped convex parts 14 and the groove parts 13 are symmetrically arranged on two sides of the shaft sleeve 11, and the abrasion of the first arc-shaped convex parts 14 can be effectively reduced. In addition, be equipped with friction cover 4 in the axle sleeve 11, friction cover 4 is the elastomer, friction cover 4 with pivot 2 cup joints, and with the 14 interference fit of first arc convex part, the arbitrary rotation angle state of handrail body 1 can be fixed to the extrusion force that 4 interference fit of friction cover produced, avoids appearing the handrail from the state of packing up because of the chair slope or receive external force to trigger suddenly to rotate to the state of expanding. Referring to fig. 5, a screw hole 22 is formed in the center of the rotating shaft 2, a bolt 5 is locked in the screw hole 22, and the bolt 5 fixes the friction sleeve 4 and the rotating shaft 2. The armrest body 1 and the guide mechanism 3 are preferably integrally formed, and the armrest further comprises end covers 6 arranged at two ends of the shaft sleeve 11.
As shown in fig. 6, the present invention further provides a toilet bowl 7 including the above rotatable armrest. When the rotatable armrest is installed, the left and right rotatable armrests may be fixed to a mounting plate, and then the mounting plate may be fixed to the toilet bowl 7, or the rotatable armrests may be installed on the left and right sides of the toilet bowl 7, respectively, and the installation of the rotatable armrests is not limited by the width of the toilet bowl 7. Will the utility model discloses a rotatable handrail is used to closestool 7, multiplicable old man, children, disabled person etc. like the security in lavatory.
To sum up, implement the utility model discloses following beneficial effect has:
The utility model provides a rotatable armrest, which comprises an armrest body and a rotating shaft rotationally connected with the armrest body, wherein a groove part and a first arc-shaped convex part arranged on the inner wall of a shaft sleeve are arranged in the shaft sleeve of the armrest body; a guide mechanism detachably connected with the rotating shaft is arranged in the groove and comprises a second arc-shaped convex part matched with the inner wall of the shaft sleeve and a third arc-shaped convex part matched with the first arc-shaped convex part; it has the following advantages:
