The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, understand the utility model technical thought required for protection so that clearer.
As shown in Figure 1, 2, for a kind of castor braking mechanism of the utility model, comprise support 6, brake lever 4; Described support 6 can be arranged on the turning cylinder of castor or be arranged on the mobile object that is positioned at the castor top; Described support 6 comprises the mounting pipe section 61 of extending and be positioned at the castor outside along its short transverse, and described brake lever 4 is actively plugged in the tube chamber of mounting pipe section 61 and can moves up and down along the bearing of trend of mounting pipe section 61; The upper end of described brake lever 4 is fixed with sleeve 3, and lower end is provided with when brake lever 4 moves down for the bearing surface with supporting castor (wherein, this contact surface can be the ground of supporting castor or work top etc.) retainer 41 of contact to play braking action; Retainer 41 passes the outside of these mounting pipe section 61 lower ends; This castor braking mechanism also comprises between mounting pipe section 61 and sleeve 3 and for apply the upwards spring 5 of thrust to sleeve 3, concrete, and described spring 5 is between the interior diapire of the bottom of sleeve 3 and mounting pipe section 61.In use, drive 4 times enforcement retainers 41 of brake lever contacts with ground by exerting pressure, thereby play brake function, thereby and by cancelling pressure, can make brake lever 4 upward movement under the elastic force effect of spring 5 make retainer 41 built on stilts, can automatically terminate brake.Due to of the present utility model simple in structure, easy for installation, be conducive to reduce cost of manufacture.
Preferably, described brake lever 4 is inserted in the tube chamber of mounting pipe section 61 rotationally, the upper end of the outer wall of described sleeve 3 is provided with limited step 31, and the upper end of described mounting pipe section 61 is useful on the support portion 62 of the limited step 31 of blocking, the groove 63 embedded for limited step 31 around the pivot center circumferential row cloth of brake lever 4.In the process of rotating at castor, by limited step 31 being placed in to the top of support portion 62, can utilizing blocking of support portion 62 to do in order to avoid brake lever 4 because colliding up and down the situation that the mistake brake occurs, thereby improve reliability of service.
For the ease of regulating the rotation of brake lever 4, this castor braking mechanism also comprises and is installed in rotation on support 6 and is sleeved on sleeve 3 outsides with the adjustment disk 2 for rotating with moving sleeve 3.Concrete, the shape of the groove of described adjustment disk 2 and sleeve 3 is complementary, and, by utilizing the restriction of limited step 31 shapes, when adjustment disk 2 rotates, can be with moving sleeve 3 to rotate, and this sleeve 3 can move up and down with respect to adjustment disk 2.This castor braking mechanism also comprises the reversing handle 1 that is installed in rotation on brake lever 4 upper ends, by operation reversing handle 1, can drive brake lever 4, moves downward, and the rotation direction that can utilize reversing handle 1 to regulate castor.
The lower end of the outer wall of sleeve 3 is provided with boss portion 32, be provided with the sliding area 64 circumferentially extended along it in described mounting pipe section 61, this boss portion 32 is slidably mounted in this sliding area 64, and the two ends of sliding area 64 are provided with stop flange, with for limiting the slewing area of sleeve 3.Wherein, the scope of this sliding area 64 can be set according to actual demand.
The working process of this castor braking mechanism is as follows: as shown in Figure 4, first rotate adjustment disk 2 and the limited step of sleeve 3 31 is turned to the top of the groove 63 of mounting pipe section 61, by applying downward pressure, make the limited step 31 of sleeve 3 move in groove 63, and the retainer 41 that synchronously drives brake lever 4 moves downward kiss the earth, thereby realized the self-actuating brake of castor, also played the effect of stable equilibrium's object simultaneously; And after cancelling pressure, thereby sleeve 3 upward movement under the elastic force effect of spring 5 drives retainer 41 built on stilts, and can automatic un-brake.As shown in Figure 3, under the proper motion state of castor, by moving sleeve 3 and make the limited step 31 of sleeve 3 be positioned at the top of support portion 62, and can limit sleeve 3 by the effect of blocking that utilizes support portion 62, move down, thereby make the retainer 41 of brake lever 4 can't kiss the earth, lose braking action, to guarantee the flexible rotating of castor.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
