As shown in fig. 1-3, the utility model discloses a connecting rod transmission structure capable of rotating up and down, which comprises a base 1, wherein a mounting bracket 2 is arranged on the base 1, a shell 3 is connected onto the mounting bracket 2, and the shell 3 and the base 1 can rotate up and down in a reciprocating manner relative to the base 1 through a connecting rod transmission mechanism.
Through the connecting rod transmission mechanism, the shell 3 is driven to rotate up and down in a reciprocating mode relative to the base 1, so that the shell 3 can swing up and down in a reciprocating mode, and the structure is simple.
Therefore, when the warm air blower is used on the warm air blower, the up-and-down change of the wind direction of the warm air blower can be realized through the connecting rod transmission mechanism, so that the use of a user is facilitated, and the use feeling of the user is improved.
Wherein, connecting rod drive mechanism is including establishing motor element 4 on casing 3, crank 5 of being connected with motor element 4 transmission, connecting rod 6 of being connected with crank 5 transmission, establish on installing support 2 and through the transmission carousel 7 that second external tooth 9 is connected with connecting rod 6 transmission, transmission carousel 7's circumference still is equipped with the first external tooth 8 adjacent with second external tooth 9, casing 3 goes up to extend between first external tooth 8 and the second external tooth 9 has transmission post 10. With the arrangement, when the shell 3 needs to rotate upwards, the motor assembly 4 works, the crank 5 is driven to rotate by forward rotation of the motor assembly 4 and is transmitted to the connecting rod 6 to drive the transmission turntable 7 to rotate through the second external teeth 9, the first external teeth 8 on the transmission turntable 7 also rotate along with the transmission turntable 7, and the transmission column 10 is pushed through the first external teeth 8 to realize the upward rotation of the shell 3; on the contrary, when the shell body rotates downwards, the motor component 4 rotates reversely to drive the crank 5 to rotate, and the connecting rod 6 is driven to drive the second outer teeth 9 to push the transmission column 10 to realize the downward rotation of the shell body 3, so that the structure is simple.
Wherein, the base 1 and the shell 3 are limited by a limit structure to limit the rotation angle of the shell 3 relative to the base 1. The rotation angle of the shell 3 is limited through the limiting structure, so that the swing amplitude of the wind direction is guaranteed.
The limiting structure comprises a limiting part arranged on the mounting bracket 2, and third external teeth and fourth external teeth 12 which are respectively arranged in the circumferential direction of the transmission turntable 7 and form limiting matching with the limiting part; there is a circumferential distance between the third outer tooth and the fourth outer tooth 12, and a limiting member is located on the circumferential distance, and is used to form a limiting fit with the third outer tooth and the fourth outer tooth 12. When transmission carousel 7 rotates, establish the third external tooth on transmission carousel 7 and the same rotation of fourth external tooth 12, because the locating part is located the circumferencial distance between third external tooth and the fourth external tooth 12, so transmission carousel 7 rotates one of them must can realize spacingly with the locating part contact of third external tooth or fourth external tooth 12, so, can ensure the rotation range of casing 3 through the locating part, can ensure to realize under the spacing condition, the structure is comparatively simple.
