SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the utility model provides a school badge card that is difficult for droing.

The utility model discloses a school badge card, including the casing, the casing divide into: the epitheca, with the inferior valve of epitheca interlock and the cavity between epitheca and the inferior valve, set up hole and at least one fixing device on the inferior valve, fixing device include: needle, metal ball, solid fixed ring and spring, the needle pass through the hole and alternate in the solid fixed ring, the metal ball set up in solid fixed ring and the first space department of stitch, the spring set up in the second space department between solid fixed ring and the epitheca, the needle have the recess of many places wavy, the metal ball card be in recess department, when pulling out the needle with strength more, the metal ball card is tighter when the recess, so that the needle be difficult to extract, when strong magnetism attracts the spring, the metal ball can break away from the recess, so that the needle can extract from the hole.

Furthermore, the fixing ring is cylindrical, three holes are formed in the side face of the fixing ring and used for placing three metal balls, and the three metal balls can move in the fixing ring.

Furthermore, the fixing ring is a metal piece.

Furthermore, the two fixing devices are symmetrically arranged on the lower shell.

Further, the needle is in the shape of a long nail.

Furthermore, the school badge is square.

Further, a container for placing the fixing device is arranged in the cavity, and the container is of a structure with a large top and a small bottom.

The school badge implementing the technical scheme has the following technical effects:

be different from fixed school badge among the prior art and adopt the fixed mode of pin type, buckle formula, cause the not enough of risk of damage, droing easily, school badge card among this technical scheme need not the pin, need magnetism to inhale when taking off and dismantle, and fixed mode is firm, safer.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2, fig. 3, and fig. 4, an embodiment of the present invention is a school badge 1, including a housing 10, the housing is divided into: an upper shell 11, a lower shell 12 engaged with the upper shell 11, and a cavity between the upper shell 11 and the lower shell 12.

Set up hole 20 and at least one fixing device on inferior valve 12, fixing device includes: a needle 21, a metal ball 22, a retainer ring 23, and a spring 24.

The needle 21 passes through the hole 20 and is inserted into the fixing ring 23, the metal ball 22 is arranged at a first gap between the fixing ring 23 and the pin, the spring 24 is arranged at a second gap between the fixing ring 23 and the upper shell 11, the needle 21 is provided with a plurality of wavy grooves, the metal ball 22 can be clamped at the groove, the metal ball 22 is clamped at the groove when the needle is pulled out with more force, so that the needle 21 is difficult to pull out, and the metal ball 22 can be separated from the groove when the spring 24 is attracted by strong magnetism, so that the needle 21 can be pulled out from the hole 20.

The fixing ring 23 is cylindrical and has three holes on its side for receiving the three metal balls 22, and the three metal balls 22 are movable in the fixing ring 23.

The fixing ring 23 is a metal member.

The two fixing devices are symmetrically arranged on the lower shell 12.

The needle 21 is in the form of a spike.

The school badge 1 is square.

The working principle of the fixing device of the school badge card is as follows:

the container for placing the fixing device is designed into a structure with a big top and a small bottom on the lower cover (lower shell 12), the side surface of the needle is provided with a plurality of grooves, and the side surface of the fixing ring of the metal ball is provided with three holes for placing three metal balls, so that the metal balls always move in the fixing ring of the metal ball. The spring gives the force to the metal ball fixing ring, and the fixing ring of the metal ball moves downwards. When the needle is inserted into the hole of the lower cover, the metal ball is clamped in the groove of the needle. If the needle is pulled out with strength, the metal ball can receive horizontal force and longitudinal force along the inclined plane, and the more the needle is pulled out with strength, the more tightly the metal ball is clamped in the groove of the needle. To pull out the needle, only can be that the metal ball need move up, so under ascending strong magnetic force effect, the metal retainer plate can extrude the spring and move up, and the ball also moves along the side of container, breaks away from the recess of needle, and the needle just can be pulled out.

be different from fixed school badge among the prior art and adopt the fixed mode of pin type, buckle formula, cause the not enough of risk of damage, droing easily, school badge card among this technical scheme need not the pin, need magnetism to inhale when taking off and dismantle, and fixed mode is more firm, safer.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements and the like, which are made within the spirit and principles of the present invention.
