Fig. 1 is a schematic structural view of a fixing device of a conveying roller of the invention;
fig. 2 is a partially enlarged view of a portion a in fig. 1;
the device comprises a conveying roller 1, a clamping block 2, a first spring 3, a fixing rod 4, a sliding rod 5, a second spring 6, a push rod 7, a fixing groove 8, a clamping groove 9, a groove 10, a through groove 11, a through groove 12, a third spring 12 and a handle 13.
Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1 and 2, the fixing device of the conveying roller of this embodiment is used for fixing the conveying roller 1, and includes a fixture block 2, a first spring 3, a fixing rod 4, a sliding rod 5, a second spring 6 and a push rod 7, wherein both ends of the conveying roller 1 are axially recessed inward to form a fixing groove 8, an inner wall of the fixing groove 8 is radially recessed outward along the conveying roller to form a clamping groove 9, the first spring 3 is disposed in the clamping groove 9, the fixture block 2 is slidably disposed in the clamping groove 9 and located below the first spring 3, a lower end of the clamping groove is wedge-shaped, a groove 10 is radially opened at a front end of the fixing rod 4, a through groove 11 communicated with the groove 10 is opened at an axial center of the fixing groove, the sliding rod 5 is vertically slidably disposed in the groove 10 and penetrates through the groove 10 to extend into the through groove 11, the second spring is sleeved on the sliding rod 5, and a bottom end of the sliding rod is disposed, the top end of the fixing rod is fixedly connected with the sliding rod 5, the fixing rod 4 is slidably mounted in the fixing groove 8, the bottom of the clamping block 2 extends into the groove 10 and is pressed on the top of the sliding rod 5, the push rod 7 is slidably mounted in the through groove 11, and the front end of the push rod is tapered. During installation, the fixing rod 4 is inserted into the fixing groove 8 and moves forwards, the fixture block 2 moves upwards under the thrust action of the fixing rod 4 due to the wedge shape, and when the fixing rod 4 moves to the position where the groove 10 is aligned with the fixture block 2, the fixture block 2 moves downwards under the action of the first spring 3 and is clamped in the groove 10 to clamp the fixing rod 4, so that installation is completed; during the dismantlement, promote push rod 7 antedisplacement, because push rod 7 front end is the toper, the bottom of slide bar 5 is the wedge, push rod 7 makes slide bar 5 ejecting messenger fixture block 2 break away from recess 10 upwards, outwards remove dead lever 4, accomplish the dismantlement, at this moment, push rod 7 resets again, slide bar 5 resets under the effort of second spring 6, fixture block 2 resets under the effort of first spring 3, whole installation and dismantlement process convenient and fast can improve work efficiency effectively.
