Description

Technical Field

[0001] The utility model relates to the technical field of building nail removers, and more specifically, to a building nail remover. Background Art

[0002] In the process of construction, nails are widely used, whether in carpentry, steel bar binding or formwork installation. In order to improve construction efficiency and facilitate operation, construction nail removers came into being. However, existing construction nail removers have some shortcomings in actual use. One of the prominent problems is that when the nail is inserted deeper, it is difficult to pull out the nail only by the groove on the insertion block of the nail remover. This is because the depth of the groove on the insertion block is limited. When the nail insertion depth exceeds the depth of the groove, the groove cannot completely clamp the nail, making it difficult for the nail remover to work. In addition, the groove on the insertion block is usually a fixed size, which is difficult to adapt to nails of different lengths and thicknesses, affecting the scope of application of the nail remover.

[0003] In addition to the limitations of the insertion block groove, another problem with existing construction nail pullers is that the lever arm is short and cannot be lengthened. The length of the lever arm of the nail puller is directly related to the torque of the nail puller. The longer the lever arm, the greater the torque applied when pulling the nail, and the better the nail pulling effect. However, existing construction nail pullers usually adopt a fixed-length lever arm design and cannot be adjusted according to actual needs. In some cases, such as when the nail is inserted deeper or the nail is tightly combined with the wood, the fixed-length lever arm may not provide sufficient torque, resulting in difficulty or inability to pull the nail. In addition, the fixed-length lever arm also limits the flexibility of the nail puller and cannot adapt to the needs of nail pulling at different heights and positions. Therefore, there is an urgent need for a new type of construction nail puller that can solve the problems of insufficient depth of the insertion block groove and unadjustable lever arm length, improve nail pulling efficiency and flexibility of use, and meet the actual needs of construction.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a construction nail remover, which has the following beneficial effects:

[0017] 1. The design of the hammer mechanism solves the problem that the insertion block is difficult to penetrate when the nail is inserted deeply. By opening a notch on the insertion block, it can be stuck on the nail. At the same time, a central axis is installed on the shell, and the lever arm plate is rotatably connected to the central axis. A counterweight block is installed on the lever arm plate, and the counterweight block fits on the insertion block. An elastic sheet is installed on the side of the lever arm plate close to the insertion block, and the lever arm plate fits on the elastic sheet. When the insertion block needs to be inserted into the nail, it is meshed with the lever arm plate with force, and the counterweight block is driven to rotate quickly by the central axis. The counterweight block hammers heavily on the insertion block, generating an instantaneous impulse, inserting the insertion block into the nail, thereby ensuring the insertion depth and improving the success rate of nail removal. This design uses the impact force of the counterweight block to overcome the resistance when the nail is tightly combined with the wood, so that the insertion block can penetrate deep into the nail, providing a strong guarantee for nail removal. At the same time, the setting of the elastic sheet can reset the lever arm plate after hammering, thereby improving the frequency and efficiency of hammering.

[0018] 2. The design of the rotating mechanism allows the length of the nail remover to be adjusted according to actual needs. After the insertion block is inserted into the nail, if the length of the shell is not enough to remove the nail, the shell can be lengthened by increasing the length of the extension tube, thereby improving the applicable scope of the nail remover. At the same time, the cooperation between the one-way sheet and the spiral groove makes the installation and removal of the extension tube very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment, when it is necessary to remove the nail, the insertion block 1 is first fitted into the nail, and the nail is stuck in the groove 8. Since some nails are inserted deeper, the insertion block 1 cannot be conveniently inserted to a certain length. When the insertion length is too short, the nail removal process cannot be completed. Therefore, the insertion block 1 needs to be deeply inserted into the nail, and by pinching it hard on the force arm plate 4, the counterweight block 5 can be driven to rotate quickly through the center axis 2, and then the counterweight block 5 is heavily hammered on the insertion block 1. The insertion block 1 can be inserted into the nail through the instantaneous impulse, thereby ensuring the insertion depth and improving the success rate of nail removal.

[0030] See also Figures 2 to 5As an implementation method of a construction nail remover for a rotating mechanism: the rotating mechanism includes a rotating block 10 and a rotating shaft 11, the rotating shaft 11 is installed in the housing 6, the rotating block 10 is rotatably connected to the rotating shaft 11, and the rotating block 10 is fitted in the housing 6, a limit block 12 is provided on the side of the rotating block 10, a limit ring 13 is rotatably provided on the rotating shaft 11, the limit ring 13 is clamped on the side of the limit block 12, a fixed sleeve 14 is fixed on the rotating block 10, an extension tube 15 is coaxially provided on the fixed sleeve 14, a plurality of one-way sheets 16 are provided in the fixed sleeve 14, an insertion tube 17 is provided on the extension tube 15, and an insertion tube 17 is provided on the insertion tube 17. A spiral groove 18 is provided on the side wall of the inlet tube 17, and multiple one-way sheets 16 are respectively arranged along the spiral groove 18, and multiple one-way sheets 16 are stuck in the spiral groove 18. A clamping spring 19 is provided in the fixed sleeve 14, and the two ends of the clamping spring 19 are respectively fixedly connected to the inner wall of the fixed sleeve 14, and multiple one-way sheets 16 are respectively attached to the clamping spring 19. The fixed sleeve 14 has an internal thread with a socket sleeve 20, and the insertion tube 17 is slidably connected in the socket sleeve 20. A plurality of anti-slip grooves 21 are provided on the side wall of the socket sleeve 20, and the plurality of anti-slip grooves 21 are respectively equidistantly arranged, and a rounded corner 22 is provided on the insertion tube 17.

[0031] More specifically, when the insertion block 1 is inserted into the nail, if the length of the outer shell 6 alone is not enough to pull it out, it is necessary to increase the length of the outer shell 6. First, the corresponding extension tube 15 is inserted into the fixing sleeve 14. Due to the one-way setting of the one-way piece 16, the insertion tube 17 can be quickly inserted into the fixing sleeve 14, and then the one-way piece 16 is stuck in the spiral groove 18. The stability of the one-way piece 16 is guaranteed by the clamping spring 19, thereby fixing the extension tube 15, and then the limit block 12 is rotated to be stuck on the limit block 12, so that the limit block 12 and the outer shell 6 are fixed, thereby lengthening the outer shell 6, thereby improving the convenience of unlocking.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to remove a nail, first fit the insertion block 1 into the nail, and the nail is stuck in the slot 8. Since some nails are inserted deeper, the insertion block 1 cannot be conveniently inserted to a certain length. When the insertion length is too short, the nail removal process cannot be completed. Therefore, the insertion block 1 needs to be deeply inserted into the nail, and by forcefully pinching the force arm plate 4, the counterweight block 5 can be driven to rotate rapidly through the center axis 2, and then the counterweight block 5 is heavily hammered on the insertion block 1. The insertion block 1 can be inserted into the nail through the instantaneous impulse, thereby ensuring the insertion depth and improving the success rate of nail removal.

[0033] When the insertion block 1 is inserted into the nail, if the length of the outer shell 6 alone is not enough to pull it out, it is necessary to increase the length of the outer shell 6. First, the corresponding extension tube 15 is inserted into the fixing sleeve 14. Due to the one-way setting of the one-way piece 16, the insertion tube 17 can be quickly inserted into the fixing sleeve 14, and then the one-way piece 16 is stuck in the spiral groove 18. The stability of the one-way piece 16 is guaranteed by the clamping spring 19, thereby fixing the extension tube 15, and then the limit block 12 is rotated to be stuck on the limit block 12, so that the limit block 12 and the outer shell 6 are fixed, thereby lengthening the outer shell 6, thereby improving the convenience of unlocking.

In the above, all fixed connections are preferably welded.
