Abstract

A fixing device of retaining pieces comprises a reel and a retaining piece. A first inserting piece is arranged at one end of the retaining piece, a first blocking groove is arranged on the external side wall of the reel, a first blocking member is arranged on the opening of the first blocking groove and extends into the first blocking groove, the first inserting piece inserts into the first blocking groove, and the retaining piece penetrates through the first blocking groove. When the fixing device of retaining pieces needs to be replaced, the retaining piece is extracted and one end of a new retaining piece provided with the first inserting piece is inserted into the first blocking groove along the end surface of the first blocking groove. The first blocking member is used for preventing the retaining piece from sliding out of the first blocking groove.

Description

A kind of anchor fitting of catch

Technical field

The utility model relates to a kind of anchor fitting that is used for the sunshade upper stop piece.

Background technology

Another of the applicant part number of patent application is: announced a kind of sunshade in 201120382308.9 the patent application; Comprise spool and torsion spring; Said spool is rotatably connected on the said support; Be wound with the light tight flexible catch that do not seep water on the said spool, an end that is fixed on the said spool of said catch is a fixed end, and the other end of said catch is a free end.Fixed form in the middle of this application between catch and the spool does not limit; If adopt stickup or other non-removable mode to be fixed on the spool; Just can easily not change after catch has been broken, and catch in use, need pulling repeatedly; And often bear wind and weather, be easy to damage.

Summary of the invention

The utility model provides a kind of anchor fitting of catch to deficiency of the prior art, and catch can be changed easily.

In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of anchor fitting of catch, comprise spool and catch, and an end of said catch is provided with first inserted sheet; The lateral wall of said spool is provided with first draw-in groove; The opening part of said first draw-in groove is provided with first stop part that in first draw-in groove, extends, and said first inserted sheet inserts in said first draw-in groove, and said catch passes said first draw-in groove.When need changing, catch is extracted out, the end face that then will new catch be provided with end edge first draw-in groove of first inserted sheet inserts in first draw-in groove.First stop part is used for anti-stop tab and skids off first draw-in groove.

In the technique scheme, preferred, said spool is a cylindrical shape, and the bottom surface of said first draw-in groove is a cambered surface, and said first inserted sheet is an arc, and said first inserted sheet, said bottom surface are coaxial with said spool.

In the technique scheme, preferred, said catch has two, and an end of two said catch is fixed in same said first inserted sheet.

In the technique scheme, preferred, the both sides of said opening part respectively are provided with one first stop part.

The beneficial effect of the utility model is: when need changing, catch is extracted out, the end face that then will new catch be provided with end edge first draw-in groove of first inserted sheet inserts in first draw-in groove, changes very convenient.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.

Embodiment 1, referring to Fig. 1 to Fig. 3, and a kind of anchor fitting of catch; Comprise spool 1 and catch 2, spool 1 is a cylindrical shape, and an end of catch 2 is provided with first inserted sheet 21; First inserted sheet 21 is an arc, and the bottom surface 1b that the lateral wall of spool 1 is provided with first draw-in groove, 11, the first draw-in grooves 11 is a cambered surface.First inserted sheet 21, bottom surface 1b are coaxial with spool 1.The opening 1a both sides of first draw-in groove 1 respectively form one first stop part, 12,13, the first inserted sheets 21 that in first draw-in groove 11, extend and insert in first draw-in groove 11, and catch 2 passes first draw-in groove 1.The other end of catch 2 is provided with second inserted sheet 22 and block piece 3; Block piece 3 is provided with second draw-in groove 31; The opening 3a place of said second draw-in groove 31 is provided with second stop part 32,33 that in second draw-in groove 31, extends; Said second inserted sheet 22 inserts in said second draw-in groove 31, and said catch 2 passes said second draw-in groove 31.

Embodiment 2, and referring to Fig. 4, said catch 2 has two, and an end of two catch 2 is fixed in same first inserted sheet 21.All the other adopt the sunshade of this catch set-up mode with embodiment 1, after catch is pulled out, can extend simultaneously towards the device both sides.

Embodiment 3, and the bottom surface 1b of said first draw-in groove 11 is the plane, and first inserted sheet 21 is a rectangular shape.All the other are with embodiment 1.This structure also can realize same function, but very high to the requirement of spool thickness of pipe.

Embodiment 4, and said catch 2 has two, and an end of two catch 2 is fixed in same first inserted sheet 21.All the other are with embodiment 3.
