DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] An embodiment of the present application discloses a handheld rock drill.
[0032] like Figure 1 As shown, the handheld rock drill comprises a rock drill body 1, a drill head 2 arranged at the bottom of the rock drill body 1, a handrail 3 arranged at the top of the rock drill body 1, and a grip 4 arranged at the middle of the rock drill body 1 and arranged at an angle to the rock drill body 1. In this embodiment, the grip 4 is arranged perpendicular to the rock drill body 1.
[0033] By providing a handle 4 that is arranged at an angle to the rock drill body 1, the operator can operate the handheld rock drill by holding the armrest 3 and the handle 4 according to actual needs, which makes the operation more flexible, improves the stability of the handheld rock drill during operation, and thus improves the operating safety of the handheld rock drill.
[0034] In addition, the handrail 3 is arranged on a side of the rock drill body 1 away from the grip 4. Such a layout makes the operator's hand position more reasonable when holding the handrail 3 and the grip 4, which is conducive to maintaining the stability of the handheld rock drill and the flexibility of operation.
[0035] like Figure 1 and Figure 2 As shown, in order to facilitate the operator to feed the rock drill body 1 during the rock drilling process, a slide rail 5 is provided in the middle of the rock drill body 1, and the slide rail 5 is arranged parallel to the chisel head 2. The handle 4 is slidably connected to the slide rail 5 through a slider 6, so that the handle 4 can move along the length direction of the slide rail 5, that is, the extension direction of the chisel head 2.
[0036] During actual use, the operator keeps the hand holding the handle 4 still, and gradually pushes the hand holding the armrest 3, which can drive the rock drill body 1 to move along the extension direction of the slide rail 5, i.e., the chisel head 2, to achieve the feeding of the rock drill body 1.
[0037] like Figure 1 and Figure 2 As shown, in order to increase the stability of the handheld rock drill during operation, a locking device may be provided between the slider 6 and the slide rail 5, and the locking device is used to relatively lock or unlock the slider 6 and the slide rail 5. A switch device matching the locking device is provided on the handle 4, and the switch device is used to control the locking and unlocking of the locking device.
[0038] When the operator finishes the deep drilling operation and starts to expand the hole, there is no need to feed the rock drill body 1. At this time, the locking device can be controlled by the switch device to lock the slider 6 and the slide rail 5, thereby fixing the position of the handle 4.
[0039] like Figure 2 and Figure 3 As shown, specifically, the locking device includes a first rack 7 and a second rack 8 that can cooperate with each other. The slide rail 5 is provided with a locking groove 9 along its extension direction, and the first rack 7 is equal in length to the slide rail 5 and is arranged in the locking groove 9 of the slide rail 5. The slider 6 is provided with an unlocking groove 10 parallel to the extension direction of the handle 4 on the side close to the slide rail 5, and the second rack 8 is slidably connected in the unlocking groove 10, and the tooth surface of the second rack 8 faces the first rack 7. A first elastic member 11 is provided between the second rack 8 and the groove bottom of the unlocking groove 10, and the first elastic member 11 can use its own elasticity to provide a force pointing to the first rack 7 to the second rack 8, so that under normal conditions, the tooth surface of the second rack 8 can mesh with the tooth surface of the first rack 7, so that the second rack 8 cannot move relatively along the extension direction of the first rack 7. Since the first rack 7 is fixedly connected to the slide rail 5, the second rack 8 and the slider 6 are relatively fixed in the extension direction of the first rack 7 under the influence of the unlocking groove 10, thereby realizing the locking between the slider 6 and the slide rail 5. In this embodiment, the first elastic member 11 is a spring.
[0040] like Figure 3 and Figure 4As shown, the switch device includes a guide member 16 and a button switch 12. A button switch groove 13 perpendicular to the extending direction of the handle 4 is provided on the handle 4, and the button switch 12 is slidably connected in the button switch groove 13. A second elastic member 14 is provided between the button switch 12 and the groove bottom of the button switch groove 13, one end of the second elastic member 14 is fixedly connected to the button switch 12, and the other end is fixedly connected to the groove bottom of the button switch groove 13. The second elastic member 14 can use its own elasticity to provide a force toward the outside of the handle 4 to reset the button switch 12. A guide groove 15 parallel to the extending direction of the handle 4 is provided on the side of the button switch groove 13 away from the slider 6, and the guide member 16 is slidably connected in the guide groove 15. A connecting rod 17 is provided at the end of the guide member 16 close to the slider 6, and the connecting rod 17 penetrates the handle 4 and the slider 6 at the same time and is fixedly connected to the second rack 8. A first guide slope 18 is provided on one side of the guide member 16 close to the button switch 12, and a second guide slope 19 matching the first guide slope 18 is provided in the middle of one side of the button switch 12 close to the guide member 16, and the width of the second guide slope 19 is equal to the width of the guide member 16. In this embodiment, the second elastic member 14 is a spring.
[0041] When the operator needs to adjust the position of the handle 4 or feed the rock drill body 1, the second guide slope 19 can be made to collide with the first guide slope 18 by pressing the button switch 12. As the button switch 12 continues to be pressed, the guide member 16 will move along the guide groove 15 in the direction away from the slider 6, and drive the second rack 8 to move in the direction away from the first rack 7 through the connecting rod 17, thereby releasing the lock between the slider 6 and the slide rail 5. At this time, the operator can move the handle 4 to an appropriate position or feed the rock drill body 1. When the button switch 12 is released, the second elastic member 14 will push the button switch 12 to reset, and the first elastic member 11 will also push the second rack 8 to reset, so that the tooth surface of the second rack 8 is meshed with the tooth surface of the first rack 7 again, thereby achieving the re-locking between the slider 6 and the slide rail 5.
[0042] Anti-skid sleeves may also be provided on the handrails 3 and the grips 4. The anti-skid sleeves may be made of materials with anti-skid properties such as rubber to increase the friction between the operator's hand and the handrails 3 and the grips 4, prevent slipping during operation, and further improve the safety of the operation.
[0043] The implementation principle of a handheld rock drill in the embodiment of the present application is:
[0044] By providing the handle 4 which is arranged at an angle with the rock drill body 1 , the operator can operate the handheld rock drill by holding the armrest 3 and the handle 4 according to actual needs.
[0045] When the operator performs deep drilling operations, the operator can press the button switch 12 while holding the handle 4 to release the lock between the slider 6 and the slide rail 5. At the same time, the hand holding the handle 4 remains still, and the hand holding the armrest 3 gradually pushes the armrest 3 to drive the rock drill body 1 to move along the extension direction of the slide rail 5, i.e., the chisel head 2, to achieve the feeding of the rock drill body 1.
[0046] When the operator finishes the deep drilling operation and starts to expand the hole, the handle 4 can be adjusted to a suitable holding position, and then the button switch 12 can be released to re-lock the slider 6 and the slide rail 5, thereby fixing the position of the handle 4 and improving the stability of the handheld rock drill during the expansion operation.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
