[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the described contents.

[0019] like Figures 1 - 3 As shown, the present application provides an electric drill vibration reduction device, comprising an upper shell 1 with an opening at the lower end, a lower shell 2 with an opening at the upper end, a slider 3, a vibration reduction ring 4, and a handle; the upper shell 1 is roughly shaped like a hollow cylinder, the upper half of the lower shell 2 is roughly shaped like a hollow cylinder, and the lower half is roughly shaped like a hollow cone.

[0020] The lower shell 2 is detachably mounted on the bottom of the upper shell 1 , so that a placement cavity 6 for an electric drill is formed between the lower shell 2 and the upper shell 1 , and the placement cavity 6 is used to place the electric drill equipment.

[0021] A first damping spring 101 is provided at the top of the placement cavity 6. Specifically, the first damping spring 101 is arranged in the middle of the inner top surface of the upper shell 1; a clearance hole 201 for allowing the drill rod of the electric drill to extend outward is provided at the bottom of the placement cavity 6. Specifically, the clearance hole 201 is opened in the middle of the bottom of the lower shell 2; a positioning component 7 is provided on the side wall of the placement cavity 6, and the positioning component 7 is used to fix the position of the electric drill from the side.

[0022] A slider 3 is provided on the outer wall of the upper shell 1, and a shock-absorbing cylinder 10 is mounted on the outer side of the upper shell 1. A slide groove 1001 is provided on the inner wall of the shock-absorbing cylinder 10 along the vertical direction. The upper and lower ends of the slide groove 1001 do not penetrate the shock-absorbing cylinder 10. The slider 3 is slidably connected to the slide groove 1001. A second spring 8 is respectively provided on the upper and lower sides of the slider 3, and the free ends of the second spring 8 are respectively abutted against the corresponding ends of the slide groove 1001.

[0023] The damping cylinder 10 is covered with a damping ring 4, the diameter of the damping ring 4 is larger than the diameter of the damping cylinder 10, and a third spring 9 is arranged between the damping ring 4 and the damping cylinder 10, and the third spring 9 is evenly spaced along the circumferential direction of the damping ring 4; The vibration-damping ring 4 is provided with a supporting handle 5 .

[0024] When in use, the lower shell 2 is removed from the upper shell 1, and then the electric drill 11 is placed in the placement cavity 6, and the first damping spring 101 is pressed against the upper end of the electric drill 11, and the positioning assembly 7 is pressed against the side of the electric drill 11, so that the electric drill 11 can only move up and down, and then the lower shell 2 is installed, and the drill rod of the electric drill 11 is extended outward from the clearance hole 201.

[0025] When drilling, the user holds the support handle 5 to perform the drilling operation.

[0026] When the electric drill 11 has a vertical vibration, the electric drill 11 moves upward, compressing the first damping spring 101 to achieve primary damping in the vertical direction. Furthermore, the electric drill drives the upper housing 1 and the lower housing 2 to move up and down, thereby compressing the second spring 8 to achieve secondary damping in the vertical direction. Through the primary damping and secondary damping, the influence of the vertical vibration of the electric drill 11 on the drilling operation is effectively reduced, and the operation convenience and accuracy of the operator are improved.

[0027] When the electric drill 11 has a horizontal vibration, the electric drill 11 drives the damping cylinder 10 to deflect to one side, compressing the third spring 9 on that side, effectively reducing the influence of the horizontal vibration of the electric drill 11 on the drilling operation, and improving the operation convenience and accuracy of the operator.

[0028] In some specific embodiments, as Figure 4 shown, the positioning components 7 are evenly spaced along the circumferential direction of the placement cavity 6 and are evenly spaced along the vertical direction. The electric drill is limited at multiple points by the plurality of positioning components 7 to ensure that the electric drill 11 can only move in the vertical direction. Specifically, some of the positioning components 7 are arranged on the inner wall of the upper housing 1, and some of the positioning components 7 are arranged on the inner wall of the lower housing 2.

[0029] The positioning component 7 includes a fastening sleeve 701, a fixing plate 702, and two fastening rods 703 extending in the radial direction of the placement cavity 6. One ends of the two fastening rods 703 are respectively inserted into the fastening sleeve 701 from both ends of the fastening sleeve 701 and are threadedly connected to the fastening sleeve 701, and the threads on the two fastening rods 703 have opposite helical directions. Thus, when the fastening sleeve 701 is rotated, the two fastening rods 703 approach or move away from each other. The free end of one of the fastening rods 703 is fixedly connected to the side wall of the placement cavity 6, and the free end of the other fastening rod 703 is provided with a fixing plate 702.

[0030] When installing the electric drill, after placing the electric drill 11 in the placement cavity 6, rotate the fastening sleeve 701 to make the two fastening rods 703 move away from each other, so that the fixing plate 702 moves towards the electric drill 11 until the fixing plate 702 is in contact with the outer side surface of the electric drill 11. Thus, the fixing plates 702 of the plurality of positioning components 7 surround the electric drill 11 from all around, so that the electric drill 11 can only move up and down.

[0031] In this embodiment, a fastening handle 704 is provided on the fastening sleeve 701 to facilitate the user to rotate the fastening sleeve 701.

[0032] In some specific embodiments, as Figure 5 and Figure 6As shown, the outer side of the vibration-damping ring 4 is provided with a T-shaped slide groove 402, and the T-shaped slide groove 402 is arranged around the vibration-damping ring 4. A T-shaped slider 403 is slidably installed in the T-shaped slide groove 402, and the support handle 5 is fixedly connected to the T-shaped slider 403. When in use, the support handle 5 can be rotated to a suitable angle for support, so that the staff can hold the support handle 5 in different orientations, which is more convenient to use.

[0033] In this embodiment, the supporting handle 5 includes a connecting block 501, a length adjustment rod 502, a supporting rod 503, and a locking bolt 504; the connecting block 501 is connected to the vibration damping ring 4, that is, the connecting block 501 is fixedly connected to the rotating shaft, and a through hole whose shape matches the length adjustment rod 502 is provided on the connecting block 501, and the length adjustment rod 502 is passed through the through hole so that the length adjustment rod 502 can move along the through hole; the locking bolt 504 is threadedly screwed on the side of the connecting block 501, and after passing through the connecting block 501, it abuts against the length adjustment rod 502; a supporting rod 503 is provided at one end of the length adjustment rod 502.

[0034] When in use, the overall length of the support handle 5 is adjusted by adjusting the depth of the length adjustment rod 502 inserted into the through hole, and then the locking bolt 504 is tightened to fix the position of the length adjustment rod 502, making it easier for the user to control the electric drill 11 and making it more convenient to use.

[0035] In this embodiment, the length adjustment rod 502 includes a connecting rod 5021 and a telescopic rod 5022; A telescopic rod 5022 that can be extended and retracted up and down is slidably installed on the upper end of the connecting rod 5021, and a fourth spring 505 is provided on the telescopic rod 5022; the supporting rod 503 is arranged at the free end of the telescopic rod 5022, one end of the fourth spring 505 abuts against the connecting rod 5021, and the other end abuts against the supporting rod 503.

[0036] When the electric drill 11 vibrates, after the primary and secondary vibration reduction in the vertical direction and the vibration reduction in the horizontal direction, the existing trace vibration is transmitted to the length adjustment rod 502, driving the telescopic rod 5022 to move up and down along the connecting rod 5021, thereby compressing the fourth spring 505, forming comprehensive vibration reduction, so that the staff can hold the supporting rod 503 more steadily, which is conducive to the stable progress of the drilling operation.

[0037] In this embodiment, a positioning cylinder 1002 is provided on the shock absorber cylinder 10. A positioning sleeve 401 matching the positioning cylinder 1002 is provided on the shock absorber ring 4. The third spring 9 is arranged in the positioning cylinder 1002. Through the positioning cylinder 1002 and the positioning sleeve 401, the stability of the relative position between the shock absorber ring 4 and the shock absorber cylinder 10 is effectively ensured, avoiding the technical problem that the shock absorber ring 4 slips out from above or below. At the same time, by arranging the third spring 9 in the positioning cylinder 1002, it is effectively ensured that the third spring 9 can stably play a role in shock absorption.

[0038] In some specific embodiments, as Figure 1 and Figure 2 shown, the outer diameter of the lower housing 2 matches the inner diameter of the upper housing 1. The upper end of the lower housing 2 is inserted into the upper housing 1. After the connecting bolt 202 passes through the lower housing 2 and the upper housing 1 from inside to outside in sequence, it is threadedly connected with the nut 203. During use, the nut 203 is loosened and the connecting bolt 202 is removed, then the upper housing 1 and the lower housing 2 can be separated from each other to realize the detachable connection between the lower housing 2 and the upper housing 1.

[0039] In this embodiment, a kidney-shaped hole 204 for the connecting bolt 202 to pass through is provided on the lower housing 2. In this way, the distance that the lower housing 2 is inserted into the upper housing 1 is adjustable, so that the total height of the placement cavity 6 is adjustable, and further the device can be applied to electric drills of different lengths, improving the applicability of the device.
