[0002] Impact drills, as a common type of power tool, combine impact and rotation functions and are widely used in construction, decoration, water and electricity installation, and machinery maintenance. Their core function is to drill or impact hard materials.

[0003] The housing of existing impact drills is usually a one-piece structure, and the front handle is also a one-piece structure with the housing. Both the front and rear handles are angled downwards, and the impact drill is used by manual end grip.

[0004] However, existing grip angles are often fixed and cannot be adjusted according to workers' gripping habits and actual work needs. After prolonged use, workers are prone to hand fatigue, which in turn affects work efficiency and construction quality. Therefore, a shock drill housing with heat dissipation function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an impact drill housing with heat dissipation function, which aims to improve the problem that the existing technology cannot be adjusted according to the worker's grip habits and actual operation needs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an impact drill housing with heat dissipation function, comprising a housing one, wherein the housing one is connected to a housing two by bolts, wherein the top of the housing one and the housing two are provided with a disassembly and assembly assembly, and the front of the housing one and the housing two are provided with a gripping assembly; The grip assembly includes an upper retaining ring, which is sleeved on the front outer arc surface of outer shell 1 and outer shell 2. A lower retaining ring is detachably installed on the upper retaining ring. A retaining block is slidably connected to the inner wall of the lower retaining ring. A threaded rod is threadedly connected to the bottom inner wall of the lower retaining ring. A handle is fixedly connected to the bottom of the threaded rod. A retaining groove is opened on the front outer arc surface of outer shell 1 and outer shell 2.

[0007] As a further description of the above technical solution: Both outer shell 1 and outer shell 2 have an overhead plate fixedly connected to their inner walls. Both outer shell 1 and outer shell 2 have a rear ventilation slot at their ends and a side ventilation slot in the middle of their middle sections.

[0008] As a further description of the above technical solution: The assembly / disassembly assembly includes a sliding frame, and two sets of sliding frames are provided. The two sets of sliding frames are respectively fixedly connected to the top of the first outer shell and the second outer shell. A handle is slidably connected to the inner wall of the sliding frame. A slider is fixedly connected to the bottom side wall of the handle. A screw is threadedly connected to the inner wall of the front part of the handle.

[0009] As a further description of the above technical solution: The inner wall of the first outer shell is in contact with the inner wall of the second outer shell.

[0010] As a further description of the above technical solution: The lower retaining ring is sleeved on the front outer arc surface of outer shell one and outer shell two, and the bottom of the retaining block is in contact with the top of the threaded rod.

[0011] As a further description of the above technical solution: The top of the grip contacts the bottom of the lower retaining ring.

[0012] As a further description of the above technical solution: The slider is slidably connected to the inner wall of the slide frame.

[0013] As a further description of the above technical solution: The bottom of the screw contacts the inner wall of the bottom of the slide frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the cross-shaped sliding frame and the slider work together to make the handle a stable gripping point and also flexible to be disassembled and assembled to adapt to narrow spaces or top angle operations. The rotatable upper and lower retaining rings and the slots and blocks work together to achieve multi-position adjustment of the grip angle.

[0018] 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.

[0019] Reference Figures 1-3 This utility model provides an embodiment of an impact drill housing with heat dissipation function, including a first housing 1. The first housing 1 is connected to a second housing 3 by bolts 2. The first housing 1 and the second housing 3 form a single impact drill housing, used to integrate the motor and transmission gears. A disassembly assembly 4 is provided at the top of the first housing 1 and the second housing 3 for installing a handle 42. When used in narrow spaces or at a top angle, the handle 42 can be removed via the disassembly assembly 4. A grip assembly 5 is provided at the front of the first housing 1 and the second housing 3, used to change the angle of the handle 55 to facilitate finding a comfortable grip. In the holding position, both the inner walls of the outer casing 1 and the outer casing 2 are fixedly connected to the overhead plate 31. The overhead plate 31 is provided with several sets, and the vertical surface is opened with through grooves to allow internal circulation between the outer casing 1 and the outer casing 2, providing an overhead heat dissipation effect for the motor and lamp components. The ends of both the outer casing 1 and the outer casing 2 are provided with rear ventilation slots 32, which are used to dissipate heat from the tail of the impact drill, allowing internal gas to flow out through the rear ventilation slots 32. The middle of the outer casing 1 and the outer casing 2 is provided with side ventilation slots 33, which are used to provide heat dissipation for the middle of the impact drill, allowing internal air to flow out through the side ventilation slots 33.

[0020] Reference Figures 1-3 The assembly / disassembly component 4 includes a sliding frame 41, which has two sets. The two sets of sliding frames 41 are fixedly connected to the top of the outer casing 1 and the outer casing 3, respectively. The interior of the sliding frame 41 is designed in a cross shape, which allows the handle 42 and the slider 43 to slide stably laterally. The handle 42 is slidably connected to the inner wall of the sliding frame 41. The handle 42 is used to provide a front grip position for the worker, so that the impact drill can be stably held in the worker's hand. The slider 43 is fixedly connected to the bottom side wall of the handle 42. The slider 43 and the handle 42 are in a cross shape and are used to snap into the inner wall of the sliding frame 41, so that the handle 42 can be used as a handle for easy manual handling and transportation. The front inner wall of the handle 42 is threaded with a screw 44, which is used to fix the handle 42. The position of the handle 42 can be changed by the screw 44 to provide a comfortable grip position for the worker. The slider 43 is slidably connected to the inner wall of the sliding frame 41, and the bottom of the screw 44 is in contact with the bottom inner wall of the sliding frame 41.

[0021] Reference Figure 1 , Figure 4 , Figure 5 The grip assembly 5 includes an upper retaining ring 51, which is sleeved on the front outer arc surface of the outer casing 1 and the outer casing 3. A lower retaining ring 52 is detachably installed on the upper retaining ring 51. The upper retaining ring 51 and the lower retaining ring 52 are detachably installed by bolts 2 and nuts. The two are combined to form a ring, which is used to engage the front outer arc surface of the outer casing 1 and the outer casing 3, fixing the handle 55 to the front of the impact drill. A retaining block 53 is slidably connected to the inner wall of the lower retaining ring 52. The retaining block 53 is used to engage with the retaining groove 56, fixing the angle between the lower retaining ring 52 and the handle 55. A threaded rod 54 is threadedly connected to the bottom inner wall of the lower retaining ring 52. The threaded rod 54 is used to move upward to push the retaining block 53 upward, thereby engaging with the retaining groove 56. Within 6, a limit function is achieved. The bottom of the threaded rod 54 is fixedly connected to a handle 55. The handle 55 is used to provide a comfortable grip position for the worker. Together with the gun handle at the tail of the outer shell 1 and the outer shell 2 3, the worker can hold the impact drill in both directions to maintain the stability of the impact drill during operation. The outer arc surface of the front part of the outer shell 1 and the outer shell 2 3 is provided with a slot 56. The slot 56 is provided with several sets for multiple positions to engage the locking block 53 and change the angle of the handle 55. The inner side wall of the outer shell 1 contacts the inner side wall of the outer shell 2 3. The lower locking ring 52 is sleeved on the outer arc surface of the front part of the outer shell 1 and the outer shell 2 3. The bottom of the locking block 53 contacts the top of the threaded rod 54, and the top of the handle 55 contacts the bottom of the lower locking ring 52.

[0022] Working principle: When moving the impact drill, the slider 43 at the bottom of the handle 42 and the handle 42 are in a cross shape, which can be locked onto the inner wall of the slide frame 41. This allows the handle 42 to serve as a front grip point to help the worker control the impact drill stably, and also as a lifting handle for easy handling. Furthermore, by rotating the screw 44 threaded to the front inner wall of the handle 42, the fixed position of the handle 42 can be changed to suit the worker's comfortable grip needs. When working in narrow spaces or at top angles, the handle 42 can be removed by disassembling and assembling component 4 to adapt to special working environments.

[0023] When the grip position of the handle 55 is uncomfortable, the locking block 53 can be moved downward by rotating the threaded rod 54. Then, the handle 55 can be rotated to rotate the upper locking ring 51 and the lower locking ring 52 to the desired position. Then, the reverse threaded rod 54 can be rotated to push the locking block 53 into the corresponding slot 56, thereby fixing the angle between the lower locking ring 52 and the handle 55. The handle 55 cooperates with the gun handle at the rear of the housing, allowing the worker to hold the impact drill in both directions and ensuring stability during operation.

[0024] In terms of heat dissipation of the impact drill housing, multiple sets of overhead plates 31 on the inner walls of housing 1 and housing 2 promote air circulation inside the housing through their vertical through slots, creating overhead heat dissipation conditions for components such as motors, reducing the accumulation of heat caused by direct contact between components and housing. At the same time, the rear ventilation slots 32 at the ends of housing 1 and housing 2 are responsible for tail heat dissipation, and the side ventilation slots 33 in the middle are responsible for middle heat dissipation. The two work together to form a heat dissipation path, allowing the internal hot gas to be discharged through the rear ventilation slots 32 and side ventilation slots 33, achieving efficient heat dissipation.

[0025] 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.
