Description of reference numerals
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Fig. 4 show a kind of can the screw of automatic lifting lid, this screw 30 comprises head 31, lifting parts 32 and connected successively and screws portion 33, and this head is for being resisted against the top (not shown) of this lid; In the present embodiment, the head 31 of screw adopts tack or round end.Adopt screw head structure conventional on market, versatility and the manufacturing efficiency of product can be improved.
Lifting parts 32 is for running through or ejecting lid 50, the outer surface of the bottom of lifting parts is provided with one for promoting the round platform 321 of lid, the axis of round platform and the dead in line of lifting parts, overlap the bottom surface (not shown) of round platform with the end face (not shown) screwing portion in the present embodiment; The outer surface screwing portion is provided with screw thread.
Fig. 5-8 shows a kind of assembly of lid that the utility model provides, comprise above-mentioned screw 30, also comprise lid 50 and a body 70, lid offers the shoulder hole 51 being always installed with this lifting parts, and the bottom of this shoulder hole is used for against this round platform 321, meanwhile, this round platform is used for down running through this shoulder hole along the axis of this lifting parts 32, and body 70 is threaded with the portion of screwing.
Shoulder hole structure on lid and screw suitable with screw structural is threaded with body, brings once assembling and can reach the beneficial effect of the function of meson pad.
As shown in Figure 7, in the present embodiment, shoulder hole 51 is designed to comprise the heavy stand 510, pass through aperture 511 and the restraining groove 512 that connect successively, the bottom (not shown) of this heavy stand against there being head 31, penetration hole is fed through lifting parts 32, restraining groove is used for carrying out spacing to the end face of round platform.Different shoulder hole structures can be adopted according to actual conditions.
Adopt the shoulder hole of said structure, can guarantee that screw is screwed by the portion of screwing on shoulder hole and body; During dismounting lid, the round platform on screw can prop up the restraining groove of lid, and jack-up lid slowly exceeds body surface by it, thus is able to directly take easily lid, and the screw simultaneously on lid can be stayed on lid and can not lose.
In addition, the external diameter 0.3mm larger than penetration hole 511 diameter of the end face of round platform, the external diameter that bottom surface external diameter and this of this round platform screw portion is equal, and the material of lid adopts Elastic plastic-rubber.Utilize the resiliently deformable of plastic cement can by force by the shoulder hole of screw by lid, and after having assembled, again because the end face of round platform is resisted against on lid, and then screw can not depart from lid and screw also can not be lost.Furthermore, the distance between the end face of round platform and the end face of lifting parts equals the degree of depth (not shown) of this heavy stand 510 and the degree of depth (not shown) sum of penetration hole 511; Further, the degree of depth of heavy stand and the degree of depth sum of penetration hole be less than the portion of screwing 33 be connected with body 70 part connecting length (not shown).The connecting length adopting the portion that screws to be connected with body is partly greater than the degree of depth of heavy stand and the degree of depth sum of penetration hole, just can ensure lid normal hoisting.
As Fig. 5,7 and 8 shows the action principle of the assembly of lid that the utility model provides:
As shown in Figure 5, be equipped with the lid of the screw that the utility model provides, by screwing up of the screw hole on this screw and body, lid be fastened on body.Lid is connected with the screw hole on body by the screw thread screwed in portion of screw, and what complete assembly of lid covers effect.
As shown in Figure 7, when dismantling lid, by turning screw, the end face of the round platform on screw is allowed gradually to be promoted to restraining groove place; Because the external diameter of the end face of round platform 0.3mm larger than the diameter of penetration hole, the external diameter that bottom surface external diameter and this of this round platform screw portion is equal.Now, restraining groove serves the effect that restriction screw continues to rise, and then makes lid still maintain the combination with body.
As shown in Figure 8, only have by continuing to be rotated counterclockwise screw, then lid is by the jack-up of round platform, slowly exceed body surface, when screw is unscrewed completely, then can extracting directly lid easily, and without the need to other instrument any, meanwhile, because lid is fastened between round platform on screw and head, thus the loss of screw is avoided.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
