Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Shown in Fig. 1～9.

A kind of communication radio station band switch is locked with knob, comprise lock core 25 (model can be JK422), lock housing 1, axle 5, lock core 25 is installed in the end of lock housing 1, the other end of lock housing 1 inserts housing 2 (as Fig. 3, shown in 4) small end in, the square end of 5 (as shown in Figure 7) of axle is inserted in the square stomidium of lock housing 25, it is characterized in that lock core 25 links to each other with eccentric shaft 6 (as shown in Figure 8) grafting, eccentric block on the eccentric shaft 6 inserts tongue 4 (as Fig. 5, shown in 6) on groove in, tongue 4 is actively plugged in the radially-directed hole on the lock housing 1, have the groove that matches with tongue 4 in housing 2 small end inboards, on the big end of lock housing 13, be fitted with two reeds 12, the square pole portion of axle 5 is installed between two reeds 12, cover plate 15 links to each other with housing 2 by screw 18, between cover plate 15 and housing 2, dust ring 14 is installed, between cover plate 15 and reed 12, the room is installed on the axle 5 took turns for 10 (as shown in Figure 9), locating wheel 10 is provided with two positioning boss 1001, and positioning boss 1001 contacts with corresponding boss 201 on the housing 2 big end end faces; Axle 5 ends that stretch out cover plate 15 are equipped with cam 9 and/or shaft joint 8.Be set with lasso 3 on the small end of housing 2, on an end of lock housing 1 installation lock core 25, knob 7 be installed.

For the ease of the dress of lock core 25, tear open, the utility model is provided with lock core location notch 101 in lock housing 1, spacer 2501 on the lock core 25 inserts in the lock core location notch 101, is processed with the lock core dismounting that communicates with lock core location notch 101 and uses hole 102 on the shell wall of lock housing 1, as shown in Figure 2.Under the normal condition, lock core 25 links to each other with lock housing 1 by spacer 2501, and lock core 25 can't take out from lock housing 1, when needs take out lock core 25 from lock housing 1, as long as with the hole 102 spacer 2501 being depressed, lock core 25 can be taken out from lock housing 1 with the lock core dismounting of pin on lock housing 1.
