Description

Waterproof dustproof construction of magnetic head

Technical Field

The utility model relates to the technical field of magnetic heads of financial equipment, in particular to a waterproof and dustproof structure of a magnetic head.

Background

At present, the magnetic head of financial equipment is in an open structure, water and dust are prevented through internal isolation, namely, impurities such as water and dust can enter a machine and contact with the magnetic head body and a circuit board of the magnetic head, and the scheme still has certain risks, especially in the environment with large oil stains.

At present, a magnetic head of handheld financial equipment on the market is rarely made into a waterproof structure, and when the handheld financial equipment is used in an environment with outdoor rain, indoor water splash or more dust, impurities such as dust, water, salt mist and the like easily invade the equipment to cause equipment damage or service life reduction. It is necessary to protect the structure of the head position to adapt the apparatus to the complex external environment.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a waterproof and dustproof structure of a magnetic head, wherein the position of the open magnetic head is closed, so that water, dust, oil stain, salt mist and the like can be prevented from entering a machine, and the cost is lower. To achieve the above objects and other advantages in accordance with the present invention, there is provided a magnetic head waterproof and dustproof structure including:

the magnetic head is fixedly connected with the silica gel sleeve, and the gum is sleeved on the silica gel sleeve;

the silica gel cover comprises an annular flat plate, an elastic anti-collision table, first embedded blocks and second embedded blocks, wherein the elastic anti-collision table is integrally connected with the annular flat plate, the first embedded blocks are symmetrically arranged on one opposite side of the annular flat plate, the second embedded blocks are symmetrically arranged on the other opposite side of the annular flat plate, at least two second embedded blocks are arranged on one side of the annular flat plate, embedded holes are respectively formed in the first embedded blocks and the second embedded blocks, and the embedded holes are embedded with the shell.

Preferably, a fixing claw is fixedly connected to the same side of the annular flat plate as the first embedding block, and the fixing claw is matched with the magnetic head.

Preferably, an end face of the shell close to the silica gel sleeve is provided with a magnetic head embedding groove and an elastic embedding groove embedded with the elastic anti-collision table.

Preferably, a second engaging boss is fixedly connected to one side of the elastic engaging groove, and the second engaging boss is engaged with the second engaging block.

Preferably, a first engaging boss is fixedly connected to an opposite side of the elastic engaging groove adjacent to the second engaging boss, and the first engaging boss is engaged with the first engaging block.

Compared with the prior art, the utility model has the beneficial effects that: through increasing the waterproof double faced adhesive tape of one deck between casing and the silica gel, the double faced adhesive tape has also played sealed effect when gluing silica gel on the casing. The magnetic head needs to kick back when swiping a card, so the design elastic wall is added, and the silica gel sleeve can ensure that the gum position is not pulled when moving along with the magnetic head, and the bonding force is not weakened, thereby ensuring the sealing effect after repeated use.
