Technical Field
The utility model relates to the technical field of plastic part connection, in particular to a plastic part clamping structure of a luminous part outer shell with sealing and detachability.
Background
The existing luminous element outer shell body is thin in wall thickness due to the fact that the conventional buckle connection mode cannot be used between two shells needing to be connected. If the shell is a transparent piece, the internal structure can look directly at the appearance, and meanwhile, the problem of sink marks can be brought, and in order to prevent light transmission between the shell connection, a welding or glue connection mode is generally adopted. On the plastic part with a thinner outer shell, the heat energy of the welding process can cause deformation of the part, surface sink marks, burn of the paint layer on the inner surface and exposed welding seams. Parts connected by glue are easy to be separated from each other to cause connection failure under the use scene of high temperature and high humidity, and at present, the two processes can not meet the detachable requirement, so that the purpose of maintainability can not be achieved.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model aims to provide a plastic part clamping structure with a sealing and detachable luminous part outer shell, so as to solve the problem that the conventional clamping structure is difficult to realize due to the fact that the wall thickness of a connecting part is thin, and the problems that the connecting part is easy to deform due to welding connection and easy to fall off due to glue connection.
In order to achieve the above purpose, the utility model provides a plastic part clamping structure with sealing and detachable luminous part outer shell, which comprises an upper cover plate, a lower cover plate and a metal clamp spring, wherein the top end of the lower cover plate is provided with a rod-shaped part with a head larger than a rod part, the head of the rod-shaped part faces upwards and the rod part faces downwards, the head of the rod-shaped part is in a ball shape, the bottom end of the upper cover plate is provided with an inlet and outlet opening corresponding to the rod part of the rod-shaped part, the head of the rod-shaped part above the inlet and outlet opening is provided with a spherical groove, the metal clamp spring comprises an arc-shaped part, vertical support legs are arranged below the two ends of the arc-shaped part, the metal clamp spring is sleeved on the rod-shaped part through the arc-shaped part, the metal clamp spring is inserted into the spherical groove and the inlet and outlet opening together, the two vertical support legs of the metal clamp spring are in interference fit with the inlet and outlet opening, and the two vertical support legs of the metal clamp spring are extruded to drive the arc to clamp the head of the rod-shaped part.
In the scheme, the method comprises the following steps: the tail ends of the two vertical supporting legs of the metal snap spring are symmetrically provided with inward barbs for preventing the rod-shaped piece from falling out of the upper cover plate.
In the scheme, the method comprises the following steps: the top outline of lower cover apron is the arc, the bottom outline of upper cover apron matches with the top outline of lower cover apron, and both laminating contacts, and the arc laminating has certain anti-light-transmission effect for the plane laminating.
In the scheme, the method comprises the following steps: the rod part of the rod-shaped piece is a rectangular rod or a round rod, so that the strength is high, and the processing is convenient.
The beneficial effects of the utility model are as follows: the metal clamp spring is elastically deformed and has a certain interference with a groove area of the upper cover plate, the metal clamp spring is assembled with the upper cover plate after being clamped at the head of the lower cover plate, the groove area of the upper cover plate extrudes the metal clamp spring, and the deformed area of the metal clamp spring is deformed so as to form a clamping relation with the rod-shaped piece, so that the upper cover plate and the lower cover plate are connected; in a word, the utility model realizes the clamping connection through a simple structure, has low cost and convenient operation, can be disassembled for many times, and solves the problem of light leakage of the outer shell of the luminous element through the connection mode that the rod-shaped element is inserted into the groove area.
