Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of POS machine, specifically, it is about a POS machine with a flip having a locking mechanism. BACKGROUND

[0002] The handheld POS machines on the market are generally designed as one-way paper tearing mechanisms. This design is mainly based on the consideration of technical stability and user experience. One-way paper tearing can effectively avoid the flip from being pulled off due to reverse pulling during operation, thereby preventing the printed paper roll from falling accidentally and ensuring the smooth progress of the printing operation. However, it is worth noting that in the case of market diversification, the demand for handheld POS machines by users presents diversified characteristics, among which the bidirectional paper tearing function has become a demand point of attention.

[0003] Traditionally, the flip fixing method of handheld POS machines mainly relies on the clamping force of a rubber roller spring. This design performs well in the application scenario of one-way paper tearing, but when faced with the demand for bidirectional paper tearing, it is difficult to meet the operation demand of bidirectional paper tearing while ensuring stability, because bidirectional paper tearing requires the flip to withstand a certain pulling force in any direction, and relying solely on the clamping force of the rubber roller spring is difficult to meet the operation demand of bidirectional paper tearing while ensuring stability. Therefore, it is necessary to improve. SUMMARY

[0004] In order to solve the above-mentioned problems of the prior art, the utility model provides a POS machine with a flip having a locking mechanism, which is simple in structure, meets the bidirectional paper tearing requirement, and is highly practical.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] As an aspect of the utility model, a POS machine with a flip having a locking mechanism is proposed, which comprises: a POS machine body;

[0007] a flip, one end of the flip is rotationally connected to one end of the POS machine body; the flip can rotate to cover or uncover the hopper of the paper bin of the POS machine body;

[0008] a locking unit, the locking unit is connected to the flip; the flip is locked with the POS machine body through the locking unit;

[0009] The locking unit comprises a locking body and an elastic member, a clamping hook member is formed on the locking body, the clamping hook member cooperates with the inner convex edge of the POS machine body, under the action of the elastic member, the clamping hook member is clamped with the inner convex edge of the POS machine body, and the flip and the POS machine body are in a locked state; the elastic member is located between the locking body and the flip.

[0010] Optionally, the flip cover is provided with a mounting space, and the locking unit is mounted in the mounting space.

[0011] Optionally, the flip cover is provided with a mounting space, and the locking unit is mounted in the mounting space.

[0013] Optionally, the mounting hole is provided with a mounting column, and the elastic member is sleeved on the mounting column.

[0014] Optionally, the locking body is provided with an operation protrusion, and the flip cover is provided with a clearance portion for accommodating the operation protrusion.

[0015] The flip cover with the locking mechanism of the POS machine has the beneficial effects, which are embodied in that the locking unit makes the flip cover and the POS machine body in a locked state, facilitates the user to tear paper towards the POS machine or the flip cover, and does not open the flip cover.

[0016] When the user needs to open the flip cover, the operation protrusion is pushed to extend out of the flip cover, the elastic member is further compressed, the clamping hook member is separated from the inner convex edge of the POS machine body, the flip cover and the paper bin of the POS machine body are in a free state, and the user can open the flip cover.
