DETAILED DESCRIPTION

[0025] The specific embodiment is a binding strap plug-in buckle assembly for a shifting machine, a structural schematic diagram of which is shown in the figure Figs. 1-3 The binding strap plug-in buckle assembly for the shifting machine comprises:

[0026] Two fixed belts 1, one end of each of the two fixed belts 1 is fixedly installed on two frames 8 of the shifting machine;

[0027] A male buckle 2, one end of the male buckle 2 is fixedly installed on the movable end of one of the fixed belts 1, and the end of the male buckle 2 away from the fixed belt 1 is fixedly connected with a protrusion 21;

[0028] A female buckle 3, one end of the female buckle 3 is fixedly installed on the movable end of the other fixed belt 1, and the end of the female buckle 3 away from the fixed belt 1 is provided with a groove matched with the protrusion 21;

[0029] A limiting assembly 4, the male buckle 2 and the female buckle 3 can be fixed by the limiting assembly 4 when the protrusion 21 is inserted into the groove;

[0030] The material of the fixed belt 1 includes but is not limited to a cloth strip, so that the movable end of the fixed belt 1 can move freely, after the two frames 8 of the shifting machine are rotated and closed, the user holds the male buckle 2 and the female buckle 3 with both hands respectively, inserts the protrusion 21 of the male buckle 2 into the groove of the female buckle 3, and fixes the protrusion 21 in the female buckle 3 by the limiting action of the limiting assembly 4, so that the two fixed belts 1 are fixed.

[0031] The limiting assembly 4 comprises clamping grooves 41 provided on the top and bottom of the protrusion 21, the end of the female buckle 3 away from the fixed belt 1 is provided with two spring cavities, and the limiting assembly 4 further comprises a sliding plate 42 slidingly connected in the spring cavities;

[0032] One side of the sliding plate 42 is fixedly connected with a clamping block 46, the other side of the sliding plate 42 is fixedly connected with a connecting rod 43 in the middle, the outer part of the connecting rod 43 is sleeved with a first spring 44, and the end of the connecting rod 43 away from the sliding plate 42 is fixedly connected with a handle 45, so that the user can operate the limiting assembly 4 conveniently through the setting of the handle 45.

[0033] One end of the first spring 44 is fixedly connected with the sliding plate 42, the other end of the first spring 44 is fixedly connected with the inner wall of the female buckle 3, and the first spring 44 leaves a gap between the connecting rod 43 and the inner wall of the spring cavity, so that the movement of the connecting rod 43 and the compression and reset of the first spring 44 can be satisfied.

[0034] The female buckle 3 is provided with a connecting rod groove in communication with the spring cavities, and the connecting rod groove is used for sliding of the connecting rod 43, so that the sliding of the connecting rod can be satisfied through the setting of the connecting rod groove.

[0035] The clamping block slot is used for sliding of the clamping block 46. Through the arrangement of the clamping block slot, the clamping block 46 can enter the interior of the spring cavity and the clamping slot 41.

[0036] After the two frames 8 of the shifting machine are rotated and closed, the user holds the male buckle 2 and the female buckle 3 respectively, inserts the protrusion 21 into the interior of the recess, and the arc surface of the protrusion 21 contacts the arc surface of the clamping block 46 in the process of entering the recess. The protrusion 21 can extrude the clamping block 46 to enter the interior of the spring cavity through the clamping block slot of the female buckle 3 from the interior of the recess under the action of the arc surface in the process of continuously entering. The clamping block 46 can drive the sliding plate 42 to extrude the first spring 44 in the moving process. After the protrusion 21 completely enters the interior of the recess, the clamping block 46 is opposite to the clamping slot 41 of the protrusion 21. At this time, the first spring 44 is no longer extruded and starts to reset. The sliding plate 42 and the clamping block 46 are pushed to move towards the protrusion 21 under the resetting action of the first spring 44. The protrusion 21 enters the interior of the clamping slot 41 through the clamping block slot of the female buckle 3. At this time, the protrusion 21 can be firmly fixed in the interior of the female buckle 3 under the cooperation of the clamping block 46 and the clamping slot 41. At this time, the fixing band 1, the male buckle 2 and the female buckle 3 are cooperated to realize the fixing of the two frames 8 of the shifting machine.

[0037] When it is needed to release the fixing of the frame 8, the connecting rod 43 is pulled to slide away from the female buckle 3 through the handle 45. The connecting rod 43 can drive the sliding plate 42 to move in the sliding process. The sliding plate 42 can drive the clamping block 46 to move in the moving process, until the clamping block 46 is moved out from the interior of the clamping slot 41. At this time, the protrusion 21 is moved out from the recess of the female buckle 3. At this time, the male buckle 2 and the female buckle 3 are separated, and the two frames 8 can be opened.

[0038] The back of the female buckle 3 is provided with a spring slot. The second spring 5 is arranged in the interior of the spring slot. One end of the second spring 5 is fixedly connected to the inner wall of the female buckle 3. The other end of the second spring 5 is fixedly connected with the moving plate 6. The moving plate 6 is fixedly connected with the push rod 7 at the middle of the side surface away from the second spring 5. The female buckle 3 is provided with a push rod slot in communication with the recess. The push rod slot is used for sliding of the push rod 7.

[0039] The protrusion 21 can also extrude the push rod 7 in the process of entering the groove, the push rod 7 drives the moving plate 6 to move and extrudes the second spring 5 when being extruded, the second spring 5 is in the extruded state after being extruded, when it is needed to release the fixing of the frame 8, the connecting rod 43 is slid by pulling the handle 45 to the opposite direction away from the female buckle 3, the connecting rod 43 can drive the sliding plate 42 to move in the sliding process, the sliding plate 42 can drive the clamping block 46 to move in the moving process, until the clamping block 46 is moved out from the inside of the clamping groove 41, at this time, the protrusion 21 no longer extrudes the push rod 7, at this time, the second spring 5 is no longer compressed and starts to reset, the second spring 5 can push the moving plate 6 and the push rod 7 to move to the direction close to the male buckle 2 in the resetting process, the push rod 7 can push the protrusion 21 to move out from the inside of the groove in the moving process.

[0040] In summary, the protrusion 21 is inserted into the groove of the female buckle 3, and the protrusion 21 is firmly fixed in the female buckle 3 under the cooperation of the clamping block 46 and the clamping groove 41, so that the fixing of the male buckle 2 and the female buckle 3 is more reliable, and when the male buckle 2 and the female buckle 3 are separated, the handle 45 only needs to be pulled away from the female buckle 3, and the protrusion 21 can be pushed out from the groove of the female buckle 3 through the push rod 7, so that the disassembly is convenient.

[0041] All the technical features in the embodiment can be freely combined according to actual needs.

[0042] The above embodiment is a preferred implementation scheme of the utility model, in addition, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
