DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0027] Embodiment 1:

[0028] like Figure 1-7As shown, the utility model provides a clip-type anchor that can be quickly assembled and disassembled, comprising: an outer sleeve 1, a clip 2 and a propeller 3 are installed in the outer sleeve 1, a connecting tube 4 is fixedly installed on one end of the clip 2, a fixing ring 5 is fixedly installed on the outer ring of the connecting tube 4, a plurality of plug holes 6 are provided between the fixing ring 5 and the connecting tube 4, the fixing ring 5 is fixedly installed in the outer sleeve 1, an extrusion tube 7 is sleeved and installed on the clip 2, an inner sleeve 11 is installed on one side of the fixing ring 5, and the inner sleeve 11 is fixedly connected to the outer sleeve 1; a plurality of guide slits 16 are evenly provided on the inner sleeve 11, so that the end surface of the inner sleeve 11 is evenly divided into a plurality of sections, and a first inclined surface 17 and a blocking portion 18 are provided on the end surface of each section, and a second inclined surface 19 is provided on the blocking portion 18. It is worth noting that the slope of the first inclined surface 17 is small, the slope of the second inclined surface 19 is large, and the height of the blocking portion 18 is low (1-2mm left The pusher 3 includes a push tube 8, which is sleeved on the connecting tube 4 and passes through the inner sleeve 11. A plurality of support bars 9 are provided on one side of the push tube 8. The support bars 9 pass through the plug-in hole 6. A push ring 10 is fixedly installed on the end of the support bar 9. A plurality of first guide bars 12 are integrally formed and installed on the push tube 8. A plurality of first teeth 14 are evenly provided on the end. The first guide bars 12 are inserted into the guide slit 16. A plurality of second guide bars 13 are integrally formed and installed on the extrusion tube 7. The first guide bars 12 and the second guide bars 13 only differ in length, and have the same width and thickness. A plurality of second teeth 15 are installed on the end of the extrusion tube 7. The side of the second guide bar 13 is aligned with the tooth top of the second tooth 15, and the side of the first guide bar 12 is not aligned with the tooth top of the first tooth 14.When in use, the outer sleeve 1 is connected and fixed to the building. In the initial state, the second guide strip 13 of the extruded tube 7 is inserted into the guide slot 16, the steel strand is inserted into the clip 2 (it can pass through the propulsion ring 10), and then the propulsion ring 10 is pushed. Due to the engagement between the first guide strip 12 and the guide slot 16, the propulsion tube 8 is moved along the guide slot 16, so that the extruded tube 7 is in contact with the end of the propulsion tube 8. Since the side surface of the second guide strip 13 is aligned with the tooth top of the second tooth 15, the side surface of the first guide strip 12 is not aligned with the tooth top of the first tooth 14, and the first guide strip 12 and the second guide strip 13 are both in the guide slot 16, the tip of the first tooth 14 is staggered with the tip of the second tooth 15, that is, the first tooth 14 The top of the tooth faces the inclined surface of the tooth of the second meshing tooth 15 on the other side, applying a circumferential component force to the extruded tube 7, causing the extruded tube 7 to have a tendency to rotate while moving along the axial direction. When the second guide strip 13 is pushed out of the guide slot 16, the inner wall of the extruded tube 7 presses the clamping piece 2, causing the clamping piece 2 to shrink and clamp the steel strand. At the same time, since grease is applied between the extruded tube 7 and the clamping piece 2, the extruded tube 7 rotates, and the second guide strip 13 is transferred accordingly and falls on the first inclined surface 17, and then the push tube 8 is withdrawn. Since the steel strand is tightened, the extruded piece 7 has a tendency to retreat, and grease is also applied to the first inclined surface 17 and the second inclined surface 19, so that the second guide strip 13 continues to rotate along the first inclined surface 17 until it is blocked. The blocking portion 18 blocks the extrusion tube 7. Since the slope of the first inclined surface 17 is small, the retreat distance of the extrusion tube 7 along the axial direction is small, and the extrusion force of the extrusion member 7 on the clip 2 will not be reduced to failure, that is, the clip 2 at this time can still maintain sufficient clamping force on the steel strand to complete the anchoring of the steel strand. It is worth noting that at this time, the tip of the first tooth 14 and the tip of the second tooth 15 are still in a staggered state. When the steel strand needs to be removed, the pushing ring 10 is pushed to make the extrusion tube 7 contact the end of the pushing tube 8. At this time, the tip of the first tooth 14 and the tip of the second tooth 15 are still in a staggered state. Therefore, the extrusion tube 7 moves toward the exposed end of the clip 2 until the second guide strip 13 exceeds the blocking portion 18, and the first tooth 14 and the second tooth 15 are in a staggered state. 5, the second guide bar 13 rotates with the extrusion tube 7, so that the second guide bar 13 falls on the second inclined surface 19, and then the push tube 8 is withdrawn. Since the slope of the second inclined surface 19 is large and grease is applied on it, the extrusion tube 7 is retreated under the tension of the wire rope, and then the second guide bar 13 slides along the second inclined surface 19 during the retreat of the extrusion tube 7, so that the extrusion tube 7 rotates until the second guide bar 13 falls into the guide slot 16 again. At this time, the whole device returns to the initial state, and as the wire rope is tightened, the clamp 2 is gradually opened, and the extrusion tube 7 is further retreated until the clamp 2 has insufficient clamping force on the wire rope, so that the wire rope can be easily pulled out of the clamp 2. At this time, the removal of the wire rope is completed. ;

[0029] By arranging the outer sleeve 1, the clip 2, the propeller 3, the connecting tube 4, the fixing ring 5, the extrusion tube 7 and the inner sleeve 11, and utilizing the staggered cooperation of the oblique teeth, as well as the joint action of the guide slit 16, the first inclined surface 17, the blocking portion 18, the blocking portion 18 and the second inclined surface 19, the assembly and disassembly of the wire rope can be conveniently completed, and the use is more convenient and quick.

[0030] Embodiment 2:

[0031] like Figure 4 As shown, a first spring 20 is sleeved on the clip 2. When in use, the extrusion tube 7 compresses the first spring 20 while the extrusion clip 2 is fixed to the steel wire rope. The second guide bar 13 falls on the first inclined surface 17, and the push tube 8 is withdrawn. Under the action of the compressed first spring 20, an axial thrust is applied to the extrusion tube 7 to accelerate the sliding speed of the second guide bar 13 on the first inclined surface 17, that is, to increase the rotation speed of the extrusion tube 7. The same principle can accelerate the sliding speed of the second guide bar 13 on the second inclined surface 19, so that the second guide bar 13 can fall back into the guide slot 16 faster, thereby making the clip 2 fail faster and the steel wire rope can be taken out faster.

[0032] By arranging the first spring 20 on the clip 2, the axial force of the clamping member 7 can be increased, so that the wire rope can be removed quickly and conveniently.

[0033] Embodiment 3:

[0034] like Figure 2 As shown, a second spring 21 is installed on the connecting tube 4. When in use, the propulsion tube 8 is pushed to move along the guide slot 16 (axially), and then the retaining ring in the propulsion tube 8 contacts and squeezes the second spring 21. After the propulsion ring 10 is released, the extrusion piece 3 can be quickly reset under the action of the compressed second spring 21, which is convenient for the next use.

[0035] By arranging the second spring 21 to be installed on the connecting pipe 4, the extruding member 3 can be quickly reset when convenient, so as to facilitate the next use.

[0036] Embodiment 4:

[0037] like Figure 1 As shown, a rubber ring 22 is installed at one end of the outer sleeve 1, and the rubber ring 22 is arranged between the clamping piece 2 and the inner wall of the outer sleeve 1. When in use, when the clamping piece 2 is tightened or opened, it drives the rubber ring 22 to expand and contract to prevent debris from falling into the gap between the clamping piece 2 and the outer sleeve 1, so that after the clamping piece 2 is tightened, it cannot be opened due to the obstruction of debris.

[0038] By installing a rubber ring 22 at one end of the outer sleeve 1, the gap between the clip 2 and the outer sleeve 1 can be sealed to prevent foreign matter from entering, so that the clip 2 can be opened normally.

[0039] Working principle: When in use, the outer sleeve 1 is connected and fixed to the building. In the initial state, the second guide strip 13 of the extruded tube 7 is inserted into the guide slot 16, the steel strand is inserted into the clip 2 (it can pass through the propulsion ring 10), and then the propulsion ring 10 is pushed. Due to the engagement between the first guide strip 12 and the guide slot 16, the propulsion tube 8 is moved along the guide slot 16, so that the extruded tube 7 contacts the end of the propulsion tube 8. Since the side surface of the second guide strip 13 is aligned with the tooth top of the second tooth 15, the side surface of the first guide strip 12 is not aligned with the tooth top of the first tooth 14, and the first guide strip 12 and the second guide strip 13 are in the guide slot 16, the tip of the first tooth 14 and the tip of the second tooth 15 are staggered, that is, the tooth top of the first tooth 14 faces the inclined surface of the tooth of the second tooth 15 on the other side, and a circumferential component force is applied to the extruded tube 7, resulting in the extruded tube 7 having a tendency to rotate while moving along the axial direction. When the second guide strip 13 is pushed out of the guide slot 16, the inner wall of the extrusion tube 7 presses the clamping piece 2, causing the clamping piece 2 to shrink and clamp the steel strand. At the same time, since grease is applied between the extrusion tube 7 and the clamping piece 2, the extrusion tube 7 rotates, and the second guide strip 13 is transferred accordingly and falls on the first inclined surface 17. Then the push tube 8 is withdrawn. Since the steel strand is tightened, the extrusion piece 7 has a tendency to retreat, and grease is also applied on the first inclined surface 17 and the second inclined surface 19, so that the second guide strip 13 continues to rotate along the first inclined surface 17 until it is blocked by the blocking part 18. Since the slope of the first inclined surface 17 is small, the retreat distance of the extrusion tube 7 along the axial direction is small, and the extrusion force of the extrusion piece 7 on the clamping piece 2 will not be reduced to failure, that is, the clamping piece 2 at this time can still maintain sufficient clamping force on the steel strand to complete the anchoring of the steel strand, and it is worth noting that at this time, the tip of the first tooth 14 and the tip of the second tooth 15 are still in a staggered state;

[0040] When it is necessary to remove the steel strand, the push ring 10 is pushed to make the extrusion tube 7 contact the end of the push tube 8. At this time, the tip of the first tooth 14 and the tip of the second tooth 15 are still staggered. Therefore, the extrusion tube 7 is moved toward the exposed end of the clamp 2 until the second guide bar 13 exceeds the blocking portion 18. Under the staggered meshing action of the first tooth 14 and the second tooth 15, the second guide bar 13 rotates with the extrusion tube 7, so that the second guide bar 13 falls on the second inclined surface 19, and then the push tube 8 is withdrawn. Due to the slope of the second inclined surface 19 The second guide bar 13 slides along the second inclined surface 19 during the retreat of the extruded tube 7, and the second guide bar 13 falls into the guide slot 16 again. At this time, the whole device returns to the initial state, and as the wire rope is tightened, the clamping piece 2 is gradually stretched open, and the extruded tube 7 further retreats until the clamping force of the clamping piece 2 on the wire rope is insufficient, so that the wire rope can be easily pulled out of the clamping piece 2. At this time, the removal of the wire rope is completed.
