Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

Example 1: as shown in fig. 1 to 3, a piano buffer clamping handle comprises a mounting seat 1 and a connecting seat 2; the mounting seat 1 and the connecting seat 2 are fixedly connected and integrally formed; a plurality of positioning holes 11 connected with a piano keyboard cover are formed in the side wall of the mounting seat 1, and the positioning holes 11 are equidistantly distributed on the mounting seat 1; a positioning groove 3 is formed in the connecting seat 2, and a sliding block 4 is sleeved in the positioning groove 3; a connecting groove 5 for clamping the connecting shaft of the descent control device is formed on the sliding block 4, and correspondingly, a mounting opening 6 corresponding to the connecting groove 5 is distributed on the side wall of the connecting seat 2; the utility model has convenient use and good use effect, ensures the stress balance at both ends in the descending process of the piano cover, automatically adjusts the central position of the piano covers at both sides, and ensures that the piano cover is not easy to deform after being opened and closed frequently; specifically, limiting lugs 7 are symmetrically arranged in the connecting seat 2, and correspondingly, assembling grooves 8 matched with the limiting lugs 7 are formed in the sliding block 4; the limiting convex block 7 is in adaptive clamping connection with the assembling groove 8.

In the utility model, the slide block 4 can not rotate under the action of the connecting seat 2 and the assembling groove 8; the size of the limiting lug 7 is slightly smaller than that of the assembling groove 8 and can be clamped in the limiting lug; when the limiting convex block 7 is clamped into the assembling groove 8, a gap 12 is formed between the sliding block 4 and the positioning groove 3; it can also be said that leave clearance 12 between spacing lug 7 and the assembly recess 8, its clearance can be arbitrary size, and like this, the piano apron is closing the in-process, and decurrent pressure is great, and the technical design of clearance 12 can reduce the speed that the piano apron closed downwards to reduce the downward pressure of piano apron, and reduce its distortion degree, increase the stability of piano apron in the closing process, prolong the life of slow descending ware and buffer card handle.

During the use, will the utility model discloses install on the piano apron, and slowly fall the ware and install on the piano curb plate, and the card is gone into the utility model discloses an among the spread groove 5, realized slowly falling the separation of ware and buffer card handle. When the piano apron is opened and is closed, the utility model discloses the drive slowly falls the ware and rotates, can effectively slow down the speed of piano apron. Opening and closing the in-process at the piano apron, have certain distortion, because slowly fall the ware with the utility model discloses the buffer card handle can sliding connection, has avoided the distortion and the damage that causes from this.

Specifically, in the utility model, the limiting lug 7 is vertically arranged with the connecting groove 5; make 5 joints of spread groove on slowly falling the connecting axle of ware the structure more firm and stable, simultaneously, also make spread groove 5 and slowly fall the ware and be connected more convenient, meanwhile, for the convenience of spread groove 5 with slowly fall the being connected of ware, spacing lug 7 can slope with spread groove 5 and lay, and service condition selects more.

Limiting plates 9 are fixedly arranged between the limiting lugs 7 which are symmetrically arranged, the limiting plates 9 are fixedly arranged at the bottoms of the positioning grooves 3, and limiting grooves 10 which are clamped with the limiting plates 9 are arranged at the bottoms of the sliding blocks 4; the connection between the sliding block 4 and the positioning groove 3 is more stable; the buffer is rotatably connected with the clamping handle while the integral structural strength of the sliding block 4 is ensured.

The outer end of the connecting groove 5 and the sliding block 4 are in a circular arc transition structure, and a connecting port of the connecting groove 5 is in a horn-shaped structure; the connecting shaft of the buffer is conveniently clamped and connected with the connecting groove 5, and the connecting part of the upper end of the mounting seat 1 and the connecting seat 2 is in arc transition; through setting up piano buffer card handle for the piano lid is fast back slow before the whereabouts process has slowly to fall function and speed, and angle is little more slow more, can play the effect of protection person's of practicing musical instrument safety well, can reduce the piano lid moreover and be connected the produced noise of rotation with the buffer, convenient and practical.
