Description

Technical Field

[0001] This utility model relates to wrench technology, specifically a convenient wrench for switching eye bolts and handwheels. Background Technology

[0002] As is known, this invention can be used to open and close the lifting eye bolts on the can lid and the operating handwheel of the shut-off valve. This tool is portable and convenient, serving two purposes in one. The left side of the lever arm is a square sleeve, and the right side is an F-type lever arm, abbreviated as IIF wrench.

[0003] The shortcomings of the existing technology are that most of the fastening tools on some equipment in the extraction workshop or the fermentation tank lid in the fermentation workshop are eye bolts. When tightening or loosening, the operator uses a stainless steel rod or the base of an F-wrench, which may slip and scratch the hand. It is inconvenient to carry and not easy to slide to achieve the purpose of tightening or loosening, making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a convenient wrench for switching eye bolts and handwheels to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an arm, one end of which is a handheld end and the other end is a locking end, and further includes:

[0006] A square box is fixedly installed on one side of the boom's snap-fit ​​end. A lifting eyelet sleeve is movably installed inside the square box, and a lifting eyelet bolt is movably inserted into the lifting eyelet sleeve.

[0007] The clamping mechanism, located inside the square box, connects the square box and the lifting eye sleeve via a transmission. It passively fixes the insertion depth between the square box and the lifting eye sleeve using the power generated when the lifting eye bolt is tightened, while also passively clamping and fixing the lifting eye sleeve and lifting eye bolts of different sizes.

[0008] As a further description of the above technical solution: the clamping mechanism includes a cavity opened in a square sleeve, the square sleeve being open at the end away from the arm, a telescopic sleeve being fixedly installed at the center of the bottom end of the cavity, a spring rod being rotatably connected to the bottom end of the telescopic sleeve through a torsion spring bearing, the top end of the spring rod being inserted into the outside of the telescopic sleeve and rotatably connected to the lifting ring sleeve through a fixed plate.

[0009] As a further description of the above technical solution: the end face of the fixed disk is rotatably connected to the lifting ring sleeve through the bearing, and the two sides of the end face of the fixed disk are symmetrically fixedly installed with abutment rods. The abutment rods are slidably connected to the arc-shaped limiting grooves. The two sets of limiting grooves are symmetrically opened on the inner side wall of the bottom center position of the lifting ring groove opened in the lifting ring.

[0010] As a further description of the above technical solution: the abutment rod is inserted through the limiting groove and into both sides of the bottom end of the lifting ring groove. One end of the abutment rod is inserted into the lifting ring groove and abuts against the outer wall of the two sets of clamping plates. The two sets of clamping plates are rotatably installed in the lifting ring groove.

[0011] As a further description of the above technical solution: the telescopic rod has symmetrically arranged locking teeth on both sides of the bottom end of the surface. Both sides of the locking teeth can be detachably engaged with the tooth groove. There are four sets of tooth grooves, and the four sets of tooth grooves are symmetrically opened in pairs on both sides of the inner wall of the telescopic sleeve.

[0012] As a further description of the above technical solution: the ends of the two sets of clamping plates are semi-circular and adapted to the shape and size of the eyelet sleeve. One end of the two sets of clamping plates is connected to the inner side wall of the opening in the eyelet groove. The end of the clamping plate inserted into the eyelet groove is inclined towards the middle of the eyelet groove, forming an isosceles triangle shape with the two sets of clamping plates and the opening of the eyelet sleeve. The clamping plates use their own deformation ability to clamp the eyelet bolt inserted into the eyelet groove.

[0013] As a further description of the above technical solution: two sets of lever arms are provided on the other side of the locking end of the boom, and the two sets of lever arms form an F-shape with the boom.

[0014] As a further description of the above technical solution: the handheld end of the arm is fitted with an anti-slip sleeve.

[0015] The present invention provides a convenient switch eye bolt and handwheel wrench, which has the following advantages:

[0016] 1. Multi-functional use: This wrench can open and close the lifting eye bolts on the tank cover, and also open and close the operating handwheel on the shut-off valve. One wrench has two uses to meet the operating needs of different equipment.

[0017] 2. Safety and anti-slip: The handle of the boom is fitted with an anti-slip sleeve, which can effectively prevent hands from being scratched due to slippage during operation, thus improving the safety of use.

[0018] 3. High adaptability: Through the clamping mechanism, the eyelet sleeve and eyelet bolts of different sizes can be passively clamped and fixed, which is applicable to various specifications of eyelet bolts and has good versatility.

[0019] 4. Stable operation: When tightening the eye bolt, the clamping mechanism uses power to passively fix the insertion depth between the square box and the eye sleeve, preventing the eye bolt from moving during tightening or loosening, and ensuring stable and reliable operation.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-6 This utility model embodiment provides a convenient wrench solution for a switch eye bolt and handwheel: It includes: an arm 1, one end of which is a handheld end and the other end is a locking end; and further includes:

[0031] A square box is fixedly installed on one side of the snap-fit ​​end of the boom 1. A lifting eye sleeve 11 is movably installed inside the square box, and a lifting eye bolt is movably inserted into the lifting eye sleeve 11.

[0032] The clamping mechanism is located inside the square box and drives the connection between the square box and the lifting eye sleeve 11. It uses the power generated by turning the lifting eye bolt to passively fix the insertion depth between the square box and the lifting eye sleeve 11, and at the same time passively clamps and fixes the lifting eye sleeve 11 and lifting eye bolts of different sizes.

[0033] In another embodiment of the present invention, preferably, the clamping mechanism includes a cavity 4 formed in a square sleeve 3. The square sleeve 3 is open at the end away from the arm 1. A telescopic sleeve 8 is fixedly installed at the center of the bottom end of the cavity 4. A spring rod 7 is rotatably connected to the bottom end of the telescopic sleeve 8 through a torsion spring bearing 6. The top end of the spring rod 7 is inserted into the outside of the telescopic sleeve 8 and is rotatably connected to the lifting ring sleeve 11 through a fixed plate 14.

[0034] In another embodiment of the present invention, the end face of the fixed disk 14 is rotatably connected to the lifting ring sleeve 11 via a bearing. Abutment rods 15 are symmetrically fixedly installed on both sides of the end face of the fixed disk 14. The abutment rods 15 are slidably connected to the arc-shaped limiting grooves 16. The two sets of limiting grooves 16 are symmetrically opened on the inner side wall of the bottom center position of the lifting ring groove 12 opened in the lifting ring.

[0035] In another embodiment of the present invention, the abutting rod 15 is inserted through the limiting groove 16 and into both sides of the bottom end of the lifting ring groove 12. One end of the abutting rod 15 is inserted into the lifting ring groove 12 and abuts against the outer wall of the two sets of clamping plates 17. The two sets of clamping plates 17 are rotatably installed in the lifting ring groove 12.

[0036] In another embodiment of the present invention, the telescopic rod 10 is provided with symmetrical locking teeth 9 on both sides of the bottom end of the surface. Both sides of the locking teeth 9 can be detachably engaged with the tooth grooves 13. There are four sets of tooth grooves 13, and the four sets of tooth grooves 13 are symmetrically opened in pairs on the inner side walls of the telescopic sleeve 8.

[0037] In another embodiment of this utility model, the ends of the two sets of clamping plates 17 are semi-circular and adapted to the shape and size of the eyelet sleeve 11. One end of the two sets of clamping plates 17 is connected to the inner sidewall of the opening in the eyelet groove 12. The end of the clamping plate 17 inserted into the eyelet groove 12 is inclined towards the middle of the eyelet groove 12, forming an isosceles triangle shape with the opening of the two sets of clamping plates 17 and the eyelet sleeve 11. The clamping plate 17 uses its own deformation ability to clamp the eyelet bolt inserted into the eyelet groove 12.

[0038] In another embodiment of the present invention, two sets of lever arms 5 are provided on the other side of the snap-fit ​​end of the arm 1, and the two sets of lever arms 5 form an F-shape with the arm 1.

[0039] In another embodiment of this utility model, the hand-held end of the arm 1 is fitted with an anti-slip sleeve 2.

[0040] Most of the fastening tools on some equipment in the extraction workshop or fermentation tank lids in the fermentation workshop are eye bolts. When tightening or loosening, operators can use two levers to open and close the operating handwheel on the shut-off valve.

[0041] When tightening or loosening eye bolts:

[0042] After the operator manually grabs the anti-slip sleeve 2 fitted onto the boom 1, they insert the square sleeve 3 onto the outside of the eye bolt. At this time, the eye bolt is inserted into the cavity 4 inside the square sleeve 3. During the process of inserting the eye bolt into the cavity 4 inside the square sleeve 3, the eye bolt is inserted into the movable eye sleeve 11 inside the cavity 4. The clamping plates 17 on both sides of the eye groove 12 opened in the eye sleeve 11 will clamp the eye bolt on both sides. The clamping plates 17 themselves have a certain deformation capacity, so they will provide a small clamping force on the eye bolt. During the process of fully inserting the eye bolt into the eye slot 12, the eye bolt presses the eye sleeve 11 into the square sleeve 3. The eye sleeve 11 then drives the telescopic rod 10 to press into the telescopic sleeve 8 and compress the spring rod 7. After the eye bolt is fully inserted into the eye slot 12, the eye can be rotated to loosen or tighten. During the rotation of the eye, since the width of the eye bolt is smaller than the width of the eye sleeve 11, and the width of the eye sleeve 11 is smaller than the width of the square sleeve 3, the rotation of the eye sleeve 11 is divided into two parts:

[0043] Part 1: The eye bolt rotates within the eye sleeve 11. During this process, the eye bolt presses against the clamping plates 17 on both sides, tightly pressing the two sides of the eye bolt against the inner sides of the two sets of clamping plates 17. The clamping plates 17 drive the eye sleeve 11 to rotate. As the eye sleeve 11 rotates, the fixing plate 14 inserted at the end of the eye sleeve 11 slides within the limiting groove 16 along with the rotation of the eye sleeve 11, causing the contact rod 15 at the end of the fixing plate 14 inserted into the eye groove 12. This causes the contact rod 15 to press against the outer sides of the two sets of clamping plates 17, limiting the position of the clamping plates 17 and thus fixing the position of the eye bolt. This part of the movement secures the connection between the eye sleeve 11 and the eye bolt, effectively preventing loosening between the eye bolt and the eye sleeve 11 during the tightening or loosening of the eye bolt.

[0044] Part Two: After the eye bolt is fixed to the eye sleeve 11, it continues to rotate, causing the eye sleeve 11 to rotate continuously. During this process, the eye sleeve 11 is in a fixed connection with the fixed plate 14 because of the restriction between the contact rod 15 and the clamp 17 inside the square sleeve 3. Therefore, the continued rotation of the eye sleeve 11 will cause the telescopic rod 10 fixedly connected to the fixed plate 14 to rotate. The telescopic rod 10 will rotate under the action of the torsion spring bearing 6 connected to the telescopic sleeve 8 at the bottom end, thereby inserting the locking teeth 9 on both sides of the surface of the telescopic rod 10 into the four sets of symmetrical tooth grooves 13 on both sides of the inner side wall of the telescopic sleeve 8, thereby limiting the position between the telescopic rod 10 and the telescopic sleeve 8. At this time, the insertion depth of the eye bolt can be limited, thereby effectively preventing the movement of the eye bolt during the tightening or loosening of the eye bolt and affecting the tightening of the eye bolt.

[0045] After tightening the eye bolt, it needs to be removed from the square sleeve 3. The eye bolt is then released from the pressure on both sides of the eye sleeve 11. At this time, the eye sleeve 11, no longer restricted in the square box, rotates under the action of the torsion spring shaft until it separates from the tooth 9 and tooth groove 13 on the surface of the telescopic rod 10. The telescopic rod 10 then rebounds within the telescopic sleeve 8 using the rebound force of the spring rod 7. At this time, the abutment rod 15 inside the eye sleeve 11 also loses its restriction on the clamp 17, and the eye bolt can then be removed from the eye sleeve 11.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
