Abstract
The utility model relates to a case caster wheel braking switch device, which comprises a shell connected with a caster wheel base. A movable shift rod is arranged in the shell, is matched with a positioning hole of a caster wheel and is arranged horizontally, a reset spring is sleeved on the movable shift rod, a pressing type reciprocating lifting mechanism is vertically arranged in the shell, the upper end of the pressing type reciprocating lifting mechanism is connected with a pressing pedal, and the lower end of the pressing type reciprocating lifting mechanism is coupled with the inner end of the shift rod in a matching way. The device has a compact and reasonable structure. All the components are arranged in the shell, and thus the device is delicate and attractive. The caster wheel braking device can be opened or fixed rapidly through slightly treading the pressing pedal. Moreover, the device is convenient and sanitary to operate and cannot be loosened easily, and reliable positioning can be achieved.
Description
Technical field: the utility model relates to a kind of brake gear of case and bag accessory, particularly Castor for trunk or bag.
Background technology: all have the BK Brake Switch device on the general case and bag caster wheel,, prevent any rolling to make things convenient for rigid castors.The caster wheel brake gear all is directly to pull cross bar mechanism now, is used for blocking castor, and such is relatively simple for structure, but reliability of positioning is low, gets loose easily, and parts expose exquisiteness attractive in appearance inadequately.Owing to need pull, pin is stepped on underaction, often will use manual manipulation, and is unhygienic also inconvenient.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of operated by foot convenient, location failure-free Castor for trunk or bag BK Brake Switch device.
The utility model comprises the housing that is connected on the caster base, removable shift rod place housing and and the cooperation of the knock hole of castor, the shift rod level is horizontal and be with retracing spring, the also perpendicular reciprocal lifting mechanism of push type that is equipped with in the housing, the upper end of the reciprocal lifting mechanism of this push type connects pushes pedal, and the lower end then is linked with the inner end of shift rod.
Compact conformation of the present utility model is reasonable, and parts all are built in the housing, and is exquisite attractive in appearance, gently steps on to push pedal and can open fast or the rigid castors brake gear, and easy to operate health is located very reliably, is difficult for getting loose.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the structural representation of embodiment at the brake stationary state.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of embodiment in the brake open mode.
Fig. 4 is the B-B cutaway view of Fig. 3.
Fig. 5 is the decomposing schematic representation of the reciprocal lifting mechanism of push type.
The specific embodiment:
Embodiment: as depicted in figs. 1 and 2, the BK Brake Switch device is in stationary state, and housing 1 is connected on the caster base 6, and removable shift rod 2 places housing 1 and and knock hole 8 cooperations of castor 7.Shift rod 2 levels are horizontal and be with retracing spring 4, the also perpendicular reciprocal lifting mechanism 3 of push type that is equipped with in the housing 1, and the upper end of the reciprocal lifting mechanism 3 of this push type connects pushes pedal 5, and the lower end then is linked with the inner end of shift rod 2.Because general mounted in pairs castor 7 all on the caster base 6, the shift rod 2 of present embodiment has two, and the level left and right sides is horizontal in housing 1, respectively with about two castor 7 corresponding matching.
The form of the reciprocal lifting mechanism 3 of push type is multiple, and present embodiment has adopted the structure of pushing pen core in the similar stationery, as shown in Figure 5, whenever pushes once and can rise or fall once.The contact matching face of the reciprocal lifting mechanism of shift rod 2 and push type 3 lower ends is the inclined-plane, and the contact matching structure is more simple and reliable like this.
When needing castor 7 freely to roll, pin is stepped on and is pushed pedal 5 once, and the reciprocal lifting mechanism of push type 3 is risen, and shift rod 2 moves under retracing spring 4 effects and the knock hole 8 of castor 7 breaks away from and cooperates, as shown in Figure 3 and Figure 4, and can free rolling castor 7.Pin is stepped on once more, and then shift rod 2 is moved outward, and the knock hole 8 of castor 7 is blocked in the outer end, promptly switches to the brake stationary state.
