Specific embodiment

Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is illustrated.

The dust-proof block terminal of the utility model comprising box body 1 and dustproof cover 2.

Box body 1 is whole box shaped, i.e. the cuboid of the generally top end opening of box body 1.

The side wall of box body 1 is provided with internal frame body 11 with extending internally.

Dustproof cover 2 includes capping body 21, and four sides of capping body 21 upwardly extend to form side wall 22；The top of side wall 22 to Outreach body 221 is extended to form outside.

Side wall 22 is located in box body 1, and the top end face of internal frame body 11 is bonded with the bottom face of outreach body 221.

When dustproof cover 2 is installed, by the opening up of box body 1, then side wall 22 is inserted into the opening of box body 1, make side wall 22 In box body 1, until the top end face of internal frame body 11 is bonded with the bottom face of outreach body 221, dustproof cover 2 can not be continued to move to. At this point, the opening of box body 1 is sealed by dustproof cover 2 completely, dust be cannot be introduced into box body 1, so as to play dust-proof work With.

Preferably, the inner wall of internal frame body 11 is bonded with side wall 22.It can guarantee that dustproof cover 2 will not move horizontally, guarantee close Seal effect.

Further, dustproof cover 2 is that elastic material [such as PE plastics, PP plastics etc.] are made, 22 outwardly convex shape of side wall At sidewall reinforcing slot 222；The section circular arc of the outer wall of sidewall reinforcing slot 222, internal frame body 11 with a thickness of internal frame body thickness A；Side wall The top of strengthening groove 222 to outreach body 221 bottom face distance be top spacing B；Then meet top spacing B more than or equal to interior Framework thickness A.Side wall 22 is inserted into the opening of box body 1, and when being located at side wall 22 in box body 1, the inner wall of internal frame body 11 supports side wall and adds The outer wall of strong slot 222 makes the outer wall of sidewall reinforcing slot 222 that elastic deformation occur, until internal frame body 11 is located at the bottom of outreach body 221 It holds, between the top of sidewall reinforcing slot 222, the outer wall of sidewall reinforcing slot 222 restores shape.At this point, with lesser power [for example, Box body 1 it is opening down when, power caused by dustproof cover 2] when pulling dustproof cover 2, the inner wall of internal frame body 11 supports sidewall reinforcing The outer wall of slot 222 can not make the outer wall of sidewall reinforcing slot 222 that elastic deformation occur, so as to keep side wall 22 to be located at box body 1 It is interior, it can be mounted on dustproof cover 2 more securely on box body 1.

Preferably, top spacing B subtracts internal frame body thickness A equal to zero.With lesser power [for example, box body 1 it is opening down when, it is anti- Power caused by dirt lid 2] pull dustproof cover 2 when, the inner wall of internal frame body 11 supports the outer wall of sidewall reinforcing slot 222, can not make side Elastic deformation occurs for the outer wall of wall strengthening groove 222, so as to keep side wall 22 to be located in box body 1 and the top end face of internal frame body 11 It is bonded with the bottom face of outreach body 221, it can be mounted on dustproof cover 2 more securely on box body 1, and guarantee internal frame body 11 Leakproofness, guarantee dust tightness between outreach body 221.

In general, capping body 21 inwardly and outwardly convexes to form lateral strengthening groove 24 and vertical strengthening groove 23；Laterally add Strong slot 24 is vertical with vertical strengthening groove 23.It can guarantee the integral strength of capping body 21.

In general, dustproof cover 2 be transparent PE plastics or PP plastics, be molded or be blow molded be made, the wall thickness of dustproof cover 2 Relatively thin [usually within 3mm].

It is to be appreciated that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", "vertical", " water It is flat ", "top", "bottom", "inner", the instructions such as "outside" orientation or positional relationship be to be based on the orientation or positional relationship shown in the drawings, It is only the present invention and simplified description for ease of description, rather than indicating or imply signified device or element must have specifically Orientation is constructed and is operated for specific orientation, thus should not be understood as the limitation that content is protected to the utility model.

Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it It is interior.
