[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 and Figure 3This utility model provides an embodiment of a hammer for engineering testing, comprising an outer column 1, with a base plate 2 fixedly connected to the bottom end of the outer column 1. This design increases the overall stability and durability. Multiple rubber pads 3 are fixedly connected to the outside of the outer column 1. These rubber pads 3 can reduce vibration and noise generated during use and improve user comfort. An inner column 4 is slidably connected to the inner wall of the outer column 1. A rack 5 is fixedly connected to the outside of the inner column 4. Here, the inner column 4 provides stable support for the rack 5. The rack 5 is slidably connected to the top of the inner wall of the outer column 1. A top column 6 is fixedly connected to the top of the rack 5. The bottom end of the top column 6 contacts the top end of the outer column 1. Here, the outer column 1 provides stable support for the top column 6. A locking column 7 is detachably connected to the inner wall of the top column 6. The bottom end of the locking column 7 is fixedly connected to the top end of the inner column 4. A support column 8 is fixedly connected to the top end of the locking column 7. The bottom end of the support column 8 contacts the top end of the top column 6.
[0032] A hammer body 9 is fixedly connected to the inner wall of the support column 8. Two latching assemblies for providing locking function are slidably connected to the inner wall of the top column 6. The latching assembly includes a sliding column 10. The outer side of the sliding column 10 is slidably connected to the inner wall of the top column 6. The top column 6 here provides a stable sliding space for the sliding column 10. A pull button 11 is fixedly connected to the outer side of the sliding column 10. A limiting plate 12 is fixedly connected to the outer side of the sliding column 10. The limiting plate 12 here is used to prevent the sliding column 10 from leaving its sliding range. The outer side of the limiting plate 12 is slidably connected to the inner wall of the top column 6. A spring 13 is sleeved on the outer side of the sliding column 10. One side of the spring 13 is fixedly connected to one side of the inner wall of the top column 6. The other end of the spring 13 is fixedly connected to one side of the limiting plate 12. The top column 6 and the limiting plate 12 here provide stable support for the spring 13. At the same time, the spring 13 here also provides a reset function for the pull button 11.
[0033] Reference Figure 1 , Figure 2 and Figure 4 The outer column 1 is fixedly connected to the front end of the outer shell 14. The gear 16 is rotatably connected to the inner wall of the outer shell 14. The outer shell 14 provides stable support for the gear 16. The inner wall of the outer shell 14 is rotatably connected to the rotating column 15. The gear 16 is fixedly connected to the outside of the rotating column 15. The rack 5 is meshed with the gear 16. When the gear 16 rotates, it can drive the rack 5 to move up and down. The left side of the rotating column 15 is fixedly connected to the knob 17. The outside of the knob 17 is fixedly connected to two side blocks 18. The right side of the side blocks 18 is fixedly connected to the side column 19. The side column 19 and the side blocks 18 are used to ensure the stability of the knob 17. The outside of the side column 19 is slidably connected to the left inner wall of the outer shell 14. The outside of the rotating column 15 is rotatably connected to the washer 20.
[0034] The right side of washer 20 is rotatably connected to the left side of housing 14, where housing 14 provides stable support for washer 20. Spring 21 is sleeved on the outside of rotating column 15. One side of spring 21 is fixedly connected to one end of washer 20, and the other side of spring 21 is fixedly connected to one end of knob 17. Washer 20 here also ensures that spring 21 will not generate torque force and break when rotating. When height adjustment is required, knob 17 can be pulled first to make it move side column 19 out of the sliding range of housing 14. Then, rotating knob 17 will drive gear 16 to rotate, thereby driving rack 5 and inner column 4 to rise and fall, further realizing the length adjustment of hammer 9 and improving the practicality of this device.
[0035] Working principle: When using this hammer for engineering testing, the operator first needs to adjust the length of the hammer body 9 according to the testing requirements. The operator pulls the knob 17 to disengage the side post 19, supported by the side block 18, from the sliding range of the outer casing 14. At this time, the operator rotates the knob 17. Since the knob 17 is fixedly connected to the rotating post 15, and the rotating post 15 meshes with the rack 5 through the gear 16, the rotation of the knob 17 will drive the gear 16 to rotate, thereby causing the rack 5 and the inner post 4 connected to it to slide up and down in the inner wall of the outer post 1.
[0036] Since the top column 6 is fixedly connected to the top of the rack 5, the raising and lowering of the inner column 4 will simultaneously drive the top column 6 and the locking column 7 to move, thereby adjusting the height of the hammer body 9. The support column 8, as the connecting component between the hammer body 9 and the top column 6, ensures that the hammer body 9 moves stably following the top column 6. When the desired length is reached, the operator releases the knob 17, and the cooperation of the side column 19 and the second spring 21 can return to the stable position under the guidance of the outer casing 14, ensuring that the positions of the knob 17 and the rotating column 15 are locked to prevent accidental rotation during use.
[0037] At this time, the position of the sliding column 10 inside the top column 6 can be adjusted by the pull button 11. The sliding column 10 and the limiting plate 12 together provide additional fixing for the hammer body 9, ensuring the stability of the hammer body 9 during use. The spring 13 provides the restoring force of the pull button 11, ensuring that the sliding column 10 can be stably held in the set position.
[0038] During actual impact testing, the operator can directly strike the object being tested using the hammer 9. If further fine-tuning of the hammer 9 is needed, it can be adjusted again using the knob 17. The design of the entire device allows the operator to easily and accurately adjust the length of the hammer to adapt to different testing needs, while the rubber pad 3 reduces vibration and noise during use, improving user comfort.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
