The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-5, the present invention provides a technical solution:

a damping rubber strip for a ceiling curtain comprises a rubber strip structure 1;

the adhesive tape structure 1 comprises a contact strip 101 and a connecting strip 105;

contact strip 101 locates connecting strip 105 bottom, and contact strip 101 and connecting strip 105 integrated into one piece, adhesive tape structure 1 adopt the silica gel material preparation, and silica gel material ageing resistance is strong, elasticity is good. Connecting strip 105 top joint is in the card strip inslot of shaft housing bottom opening part inside wall on the smallpox curtain, and contact strip 101 lateral wall and the contact of shaft housing bottom opening part inside wall on the smallpox curtain, and adhesive tape structure 1 hides in the shaft housing bottom opening, occupation space not. When retrieving the curtain, the lower shaft member of ceiling curtain shifts up in other words to the upper shaft member, and in the lower shaft member entered into the upper shaft casing from upper shaft casing bottom opening part, two contact strip 101 inside walls contacted bottom the casing lateral wall of lower shaft member respectively, and adhesive tape structure 1 plays good cushioning effect, avoids the direct contact of lower shaft casing and upper shaft casing. The problem of paste an adhesive tape alone and expose and can influence pleasing to the eye in upper shaft or off-axial, the adhesive tape is used for the double faced adhesive tape of gluing to have the risk of coming unstuck is solved.

The adhesive tape structure 1 further comprises a positioning component 104, and the positioning components 104 are fixedly arranged on two sides of the bottom of the connecting strip 105 respectively. When connecting strip 105 top joint was in the card strip inslot of shaft housing bottom opening part inside wall on the day curtain, there can be the space between connecting strip 105 bottom lateral wall and the card strip inslot bottom, utilized locating component 104 bounce after being extrudeed to support card strip inslot bottom for connecting strip 105 top joint is more stable when the card strip inslot of shaft housing bottom opening part inside wall on the day curtain, avoids connecting strip 105 to drop.

Specifically, the connecting bar 105 is designed to have a structure with a cylindrical top and a square bottom. The cylindrical structure at connecting strip 105 top and the card strip groove adaptation of shaft housing bottom opening part inside wall on the ceiling curtain, card strip groove import is less than its top post chamber for the cylindrical structure at connecting strip 105 top is more stable after with card strip groove joint.

Further, the contact strip 101 is designed to be in a right-angle trapezoid structure, and the inner side of the contact strip 101 is provided with a contact surface 103;

wherein, the contact surface 103 adopts a bevel design; the inclined plane design of contact surface 103 and the bottom adaptation of the casing lateral wall of lower shaft spare can laminate with the casing lateral wall bottom of lower shaft spare.

Wherein, the contact strip 101 is provided with a through hole 102, the through hole 102 penetrates through two ends of the contact strip 101, the through hole 102 adopts a crescent design, and a convex surface of the through hole 102 faces the contact surface 103. The extrusion force is dispersed by perforating hole 102 when contact surface 103 is compressed, causes contact surface 103 to bear bigger extrusion force, takes place the bigger extrusion of deformation, is favorable to eliminating the sound that produces of lower shaft member and upper shaft member collision to the extrusion force that crescent perforating hole 102 bore is dispersed by the radian for contact surface 103's bearing capacity is better.

Still further, the positioning assembly 104 includes an extrusion strip 1041 and a positioning strip 1042, the outer side of the extrusion strip 1041 adopts an arc structure design, and the outer side of the extrusion strip 1041 is attached to the bottom of the inner side wall of the clamping strip groove of the inner side wall at the bottom opening of the upper shaft housing of the ceiling screen. The inner side of the extrusion strip 1041 is fixedly connected with the bottom side of the connecting strip 105 through the positioning strip 1042.

Furthermore, the positioning bars 1042 adopt a diamond structure design, and the positioning bars 1042 are hollow; when the positioning bar 1042 of the diamond-shaped structure is extruded, the bevel edge of the diamond-shaped structure is relatively forked, the bevel edge of the diamond-shaped structure can bear larger acting force, larger reaction force can be generated to act on the extrusion bar 1041, the extrusion bar 1041 is abutted against the bottom of the inner side wall of the clamping bar groove at the bottom opening of the upper shaft shell of the ceiling curtain, and the positioning effect is better.

Wherein, the two side ends of the positioning bar 1042 are set to be a plane 1042b, and the plane 1042b is set so that the two side ends of the positioning bar 1042 are better connected with the inner side of the extrusion bar 1041 and the outer side wall of the bottom of the connection bar 105. The upper and lower ends of the positioning bar 1042 are set to be arc-shaped surfaces 1042a. The arc-shaped surfaces 1042a are arranged to provide a larger reaction force when the inclined edges of the rhombus structures of the positioning strips 1042 relatively diverge, so that the bottom of the inner side wall of the clamping strip groove of the inner side wall at the bottom opening of the upper shaft housing of the ceiling screen is propped against the squeezing strip 1041 more stably.

The working principle is as follows: the top of the connecting strip 105 is clamped in a clamping strip groove of the inner side wall of the bottom opening of the upper shaft shell of the ceiling curtain, the outer side of the extrusion strip 1041 is attached to the bottom of the inner side wall of the clamping strip groove of the inner side wall of the bottom opening of the upper shaft shell of the ceiling curtain, the reaction force of the positioning strip 1042 acts on the extrusion strip 1041 to enable the extrusion strip 1041 to abut against the bottom of the inner side wall of the clamping strip groove, the outer side wall of the contact strip 101 is in contact with the inner side wall of the bottom opening of the upper shaft shell of the ceiling curtain, and the adhesive tape structure 1 is hidden in the opening of the bottom of the upper shaft shell.

When the curtain is recovered, the lower shaft of the ceiling curtain is equivalent to the upper shaft and moves upwards until the lower shaft enters the upper shaft shell from the opening at the bottom of the upper shaft shell, the contact surfaces 103 of the inner side walls of the two contact strips 101 are respectively contacted with the bottom of the outer side wall of the shell of the lower shaft, and when the contact surfaces 103 are pressed, the extrusion force is dispersed by the through holes 102, so that the contact surfaces 103 can bear larger extrusion force, and the deformation is larger in extrusion, thereby being beneficial to eliminating the sound generated by the collision of the lower shaft and the upper shaft.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
