Description

Technical Field

[0001] This utility model relates to the field of steel door polishing technology, and in particular to a handheld steel door polishing tool. Background Technology

[0002] Polishing steel doors is an important maintenance process designed to remove rust, dirt, or unevenness from the surface to restore its original appearance and functionality.

[0003] A search revealed a handheld grinding tool (authorization announcement number: CN 220113002 U), which "includes a housing and a housing end cap, the housing and the end cap being snapped together by a mounting plate installed on the left side of the housing end cap; a mounting plate is installed on the inner wall of the housing, and two sets of columns are provided on the right side of the mounting plate, penetrating the housing end cap; a circular plate is installed on the right end of the columns by a nut, and a limit post is installed in the middle of the circular plate by a nut, penetrating the housing end cap; a spring is sleeved on the surface of the limit post; a protective body is installed on the left side of the mounting plate, penetrating the left wall of the housing, and the mounting plate moves within the housing by pressing the circular plate. This utility model solves the problem that when grinding inside holes, the grinding body cannot extend, resulting in the grinding body being unable to grind deep areas of the hole, thus reducing the practicality of the grinding tool."

[0004] Based on the aforementioned technologies, the applicant believes that the protective covers of existing handheld steel door grinding tools are mostly welded or bolted between the grinding tool and the grinding disc. Replacing the protective cover after it is damaged is inconvenient. In order to address the above problems, we have introduced a handheld steel door grinding tool. Utility Model Content

[0005] This utility model discloses a handheld steel door grinding tool, which aims to solve the technical problem that the protective cover of existing handheld steel door grinding tools is mostly welded or bolted between the grinding tool and the grinding disc, and it is inconvenient to replace the protective cover after it is damaged.

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] Reference Figure 1 - Figure 5A handheld steel door polishing tool includes a polishing machine body 1. One end of the polishing machine body 1 is fixedly connected to a handle 2, and the other end of the polishing machine body 1 is rotatably connected to a polishing disc 4. A protective mechanism is provided between the polishing machine body 1 and the polishing disc 4. The protective mechanism includes an adjustment groove 51, which is opened on the outside of the polishing machine body 1. The bottom of the inner wall of the adjustment groove 51 is symmetrically provided with mounting grooves 52. A sliding rod 53 is fixedly connected inside the adjustment groove 51. Moving blocks 54 are symmetrically slidably connected to the outside of the sliding rod 53. A stabilizing spring 55 is sleeved on the outside of the sliding rod 53 and between the two moving blocks 54. A fixing rod 510 is fixedly connected to the side of the two moving blocks 54 that is far apart from each other. A push plate 56 is fixedly connected to the outside of the two moving blocks 54. A protective cover 57 is provided between the polishing machine body 1 and the polishing disc 4. A connecting rod 58 is symmetrically fixedly connected to the top of the protective cover 57. An insertion hole 59 is opened on the top of the two connecting rods 58. A base 6 is fixedly connected to the top of the main body 1 of the grinder, and a second handle 7 is fixedly connected to the top of the base 6.

[0024] In the above technical solution, considering that the protective covers of existing handheld steel door grinding tools are mostly welded or bolted between the grinding tool and the grinding disc, and that replacing the protective cover after it is damaged is inconvenient, the following specific operation is performed to solve this problem:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the two push plates 56 move toward each other, and the two moving blocks 54 slide toward each other on the outside of the slide bar 53, thereby compressing the stabilizing spring 55. Then, the protective cover 57 is placed between the grinder body 1 and the grinding disc 4. Then, the two connecting rods 58 are inserted into the two mounting slots 52. Then, the hands holding the two push plates 56 are released. Under the tension of the stabilizing spring 55, the two fixing rods 510 are pushed into the insertion hole 59. Through the protective mechanism, the protective cover 57 can be quickly installed and removed. During the installation and removal process, no external tools are needed. It also avoids the difficulty of disassembling welded connections. This allows the protective cover 57 to be quickly and timely replaced after damage. The structure is simple and highly practical.

[0026] Reference Figure 1 - Figure 5In a preferred embodiment, a protective frame 8 is fixedly connected to the outer side of the grinder body 1. The bottom of the protective frame 8 is horizontal, and a rubber base 9 is fixedly connected to the bottom of the protective frame 8. The size of the fixing rod 510 matches the size of the insertion hole 59, and the fixing rod 510 and the insertion hole 59 cooperate with each other. A collection groove 10 is provided on the side of the protective frame 8 near the grinding disc 4. A connecting wire 3 is fixedly connected to the outer side of the first handle 2, and the other end of the connecting wire 3 is connected to an external power source. The protective frame 8 provides auxiliary protection for the operator, and the rubber base 9 allows the grinder body 1 to be placed on the ground when not in use, preventing the grinder body 1 from rolling.

[0027] Working principle: In actual use, the operator first connects the power cord 3 to the external power source, then pinches the two push plates 56 to move them closer together. This causes the two moving blocks 54 to slide closer together on the outside of the slide bar 53, thus compressing the stabilizing spring 55. Then, the protective cover 57 is placed between the main body 1 of the grinder and the grinding disc 4. Next, the two connecting rods 58 are inserted into the two mounting slots 52. Then, the operator releases the grip on the two push plates 56. Under the tension of the stabilizing spring 55, the two fixing rods 510 are pushed into the socket 59, completing the installation of the protective cover 57. Then, the operator holds the first handle 2 with one hand and the second handle 7 with the other hand, starts the main body 1 of the grinder, and begins grinding the steel door.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
