Abstract

The utility model relates to a bicycle saddle lockup device, comprising a hollow seat bar, a sleeving block, a positioning fixture block, a clamp block and a screwing mechanism, wherein the sleeving block is fixed on the seat bar; the positioning fixture block is disposed on the sleeving block and the clamp block is arranged above the positioning fixture block; two slots are respectively arranged at the corresponding places on the face-to-face sides of the positioning fixture block and the clamp block to match with the screwing mechanism to clamp the relative part of the saddle; an elastomer is arranged between the positioning fixture block and the clamp block. When the screwing mechanism is disengaged, the elastomer enables the positioning fixture block and the clamp block to automatically separate and leave a space between them for the installation of the saddle. The utility model is easy and convenient to operate; the installation of the saddle is time-saving and labor-saving.

Description

The bicycle saddle cushion locking mechanism

Technical field

The utility model relates to a kind of bicycle saddle cushion locking mechanism, particularly a kind of more convenient bicycle saddle cushion locking mechanism of seat cushion that assembles.

Background technology

Present bicycle saddle cushion locking mechanism on the market, referring to Fig. 1, also can reach the effect of locking seat cushion, but during the assembling seat cushion, because of location fixture block 5 and clamp 6 are subjected to the influence of self gravitation, can fit together, therefore must be earlier with hand steered fixture block and the clamp of firmly locating, and make it isolate certain space, insert and lock for seat cushion.So design-calculated bench lock locking structure causes installation extremely inconvenient, time-consuming, effort.

The utility model content

Technical problem to be solved in the utility model is: the bicycle saddle cushion locking mechanism that a kind of seat cushion convenient for assembly is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle saddle cushion locking mechanism, comprise that a hollow seat bar, a socket block, a location fixture block, a clamp and screw togather mechanism, described socket block is fixedly arranged on the bar, the location fixture block is placed on the socket block, clamp is arranged at fixture block top, location, the opposite face corresponding position of location fixture block and clamp is respectively equipped with two draw-in grooves, be used for cooperating screwing togather the corresponding position that mechanism clamps seat cushion, be provided with an elastic body between location fixture block and the clamp.

The beneficial effects of the utility model are: when location fixture block and clamp are screwing togather under the situation that mechanism loosens, elastic body can make location fixture block and clamp isolate certain space automatically, and seat cushion is installed.Easy to operate, quick, the assembling seat cushion is saved time, laborsaving.

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

The specific embodiment

Please refer to Fig. 2 and Fig. 3, the utility model bicycle saddle cushion locking mechanism be used for locking seat cushion of bicycle comprises a socket block 20, location fixture block 30, a clamp 40 and an elastic body 50 on a hollow seat bar 10, the fixing present bar 10.In the present embodiment, described elastic body 50 is a coil spring.

The upper surface of socket block 20 is established the circular arc-shaped recess 201 of tool tooth line, and offers a long slot 202 in the middle part.

The bottom 301 of location fixture block 30 is the circular arc of tool tooth line, is placed on the recess 201 of socket block 20, and the tooth line of the recess 201 of socket block 20 cooperatively interacts with the tooth line of fixture block 30 bottoms 301, location.Fixture block 30 middle parts, location also are provided with an elastic body groove 302, and elastic body groove 302 bottoms are provided with a through hole 303, the center-aligned of the long slot 202 of the center of through hole 303 and socket block 20.The top of location fixture block 30 is in establishing first draw-in groove 304 and second draw-in groove 305 respectively near the place, two ends.

Clamp 40 is arranged at fixture block 30 tops, location, and first draw-in groove 304 and second draw-in groove 305 of locating relative positioning fixture block 30 at the two ends of clamp 40 bottoms are provided with first locating groove 401 and second locating groove 402; A tapped bore 403 is also offered at clamp 40 middle parts, and is aligned with each other with above-mentioned long slot 202 and through hole 303.

The both ends of the surface of described elastic body 50 conflict respectively elastic body groove 302 bottoms of fixture block 30, location and the bottom of clamp 40.Bolt 60 passes the inside of long slot 202, through hole 303 and elastic body 50 successively and the tapped bore 403 of clamp 40 screws togather.Thereby make first locating groove 401 and first draw-in groove 304 of second locating groove, 402 cooperation location fixture blocks 30 and the

seat cushion bar

70,71 that second draw-in groove 305 clamps seat cushions 80 of clamp 40.

The tapped bore 403 of described bolt 60 and clamp 40 is formed one and is screwed togather mechanism, and the mechanism that screws togather of the present utility model is for being provided with tapped bore 403 on clamp 40, screws togather to form with the screw rod of bolt 60 to screw togather mechanism; Screwing togather mechanism also can be for being made up of screw rod and nut, and nut places the top of clamp 40, and the screw thread of screw rod and nut screws togather to form and screws togather mechanism.

Please continue 4A with reference to figure, Fig. 4 B, Fig. 5 A, Fig. 5 B, Fig. 6 A, Fig. 6 B, under the situation that bolt 60 is loosened, can isolate certain space when locating fixture block 30 and clamp 40 automatically, therefore, when assembling seat cushion 80, the user does not need to separate location fixture block 30 and clamp 40 with the hand steered fixture block 30 of firmly locating with clamp 40 and with hand specially, only need earlier clamp 40 to be rotated to and locatees the position that fixture block 30 is 90 degree directions approximately, first draw-in groove 304 and second draw-in groove 305 of location fixture block 30 are exposed, then with the seat cushion bar 70 of

seat cushion

80,71 are placed in first draw-in groove 304 and second draw-in groove, 305 places of location fixture block 30 respectively, at last clamp 40 are rotated back to initial position and lock bolt 60 and just can make location fixture block 30 and clamp 40 clamping

seats lining bars

70,71.

The utility model has taken into full account user's comfort feature, and agility more saves time the assembling seat cushion, and is laborsaving.
