Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 6, a flip-top portable printer according to a preferred embodiment of the present invention includes an upper cover group 01 and a lower cover group 02, the upper cover group 01 is slidably connected to the lower cover group 02, the upper cover group 01 includes an upper cover 10, an upper bracket 20, and a head assembly 30 having elasticity, the upper bracket 20 is disposed in the upper cover 10, the head assembly 30 is disposed on the upper bracket 20, the lower cover group 02 includes a lower cover 40, the lower support 50 and the rubber roller 60, the lower support 50 is located in the lower cover 40, the rubber roller 60 is arranged on the lower support 50, the rubber roller 60 and the head piece assembly 30 are arranged oppositely, the upper support 20 is provided with two clamping hook pieces 21, the clamping hook pieces 21 are provided with bosses 211, the lower support 50 is provided with clamping grooves matched with the clamping hook pieces 21, the clamping grooves are provided with grooves 511 matched with the bosses 211, the clamping hook pieces 21 and the clamping grooves are buckled under the action of the head piece assembly 30, and the bosses 211 are located in the clamping grooves. Two trip spare 21 keep away from articulated portion 22 one end symmetry and set up for stress balance when trip spare 21 buckles, the lock is more stable.
Preferably, the upper end surface of the boss 211 is an inclined surface, the inclined angle of the upper end surface of the boss 211 is 8-12 degrees, and chamfers or fillets are arranged at the front end and the rear end of the boss 211, the inclined surface is matched with the chamfers or fillets to enable the buckling of the clamping hook piece 21 to be smoother, and meanwhile, the clamping hook piece 21 can be prevented from automatically separating from the clamping groove; therefore, the cover opening hand feeling is good, the upper cover group 01 slides smoothly when the cover is closed, and a crisp sound of cover closing in place is generated when the cover is closed in place.
