Description

Technical Field

[0001] This application relates to the technical field of floor grinding machine equipment, and more specifically, to a floor grinding machine. Background Technology

[0002] In existing technologies, floor grinding equipment generally uses the rotation of the grinding head for position adjustment. When grinding corner areas, due to limitations in the equipment's structural design, the operating handle must be flush against the wall edge. This severely restricts the user's posture during operation, easily leading to operator fatigue and posing a risk of the handle colliding with the wall. This not only affects the continuity and quality stability of the grinding operation but may also create safety hazards for the user. Furthermore, this adjustment mechanism lacks sufficient flexibility in confined spaces, making it difficult for the equipment to adapt to different wall angles, reducing overall work efficiency and user experience.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0009] Furthermore, the plurality of slots include a first slot located in the middle of the swing end of the swing disk, a second slot disposed on one side of the first slot, and a third slot disposed on the other side of the first slot.

[0010] Furthermore, the swing adjustment component also includes: An adjustment and positioning mechanism is installed on the main support and is used to constrain and position the swing disk.

[0011] Furthermore, the adjustment and positioning mechanism includes: Fixing plate; An adjusting rod is provided, which passes through the fixed plate, and a limit post is provided at one end of the adjusting rod; Adjust the pusher pin by adjusting the lever until the pin is embedded in the slot, thus positioning the swing disk.

[0017] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0018] It should be understood that, in order to make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0019] When using existing floor grinders to grind corner areas, the limitations of the equipment's structural design mean that the operating handle must be close to the edge of the wall. This severely restricts the user's posture during operation and poses a risk of the handle colliding with the wall. This not only affects the continuity and quality stability of the grinding operation but may also pose a safety hazard to the user.

[0020] Therefore, the actual technical problem solved by this application is how to improve user comfort while achieving corner sanding.

[0021] In this embodiment, as Figure 1 As shown, a floor grinding machine includes: The main support 1 can be moved by the user. The main support 1 is the support structure for the main components of the equipment. A set of moving wheels can be set at the bottom of the main support 1 to realize the movement function. A swing adjustment component 2 is installed on the main support 1. The grinding component 3 is implemented by a motor-driven triangular grinding head 32. The triangular structure is conducive to working close to the corner of the wall. The grinding component 3 is mounted on the swing adjustment component 2. The overall position of the grinding assembly 3 is adjusted by adjusting the swing adjustment component 2 on the main support 1.

[0022] Specifically, after the operator moves the main support 1 to the work area, they change the spatial position of the grinding component 3 by operating the swing adjustment component 2. When it is necessary to grind the corner area, the swing adjustment component 2 causes the grinding component 3 to shift outward. During this process, a sufficient safe distance is always maintained between the main support 1 and the wall, allowing the operator to complete the fine grinding operation without getting too close to the wall.

[0023] Compared to existing technologies, traditional equipment relies on the rotation of the grinding head for position adjustment, which cannot change the overall distance between the equipment and the wall. This solution uses an adjustable swing mechanism to achieve overall displacement of the grinding assembly 3, effectively expanding the operating space and enabling the equipment to adapt to the spatial requirements of different work scenarios.

[0024] Through the above technical solution, this application achieves safe distance control between operators and the work surface, eliminating the user operation risks present in traditional equipment.

[0025] In this embodiment, as Figure 1 As shown, the main support 1 has a front-to-back transparent mounting area 100, and the swing adjustment component 2 is arranged in the mounting area 100.

[0026] The front-to-back transparent installation area 100 refers to an open space structure that runs through the front and back of the main support 1, which provides movable assembly space for the swing adjustment component 2.

[0027] Specifically, the mounting area 100 of the main support 1 forms a channel-like structure running from front to back, and the swing adjustment component 2 is embedded in this channel and extends along its longitudinal axis. When it is necessary to adjust the position of the grinding component 3, the swing adjustment component 2 can swing left and right within the mounting area 100, driving the grinding component 3 to move as a whole to the target working position.

[0028] In this embodiment, as Figures 1 to 3 As shown, the swing adjustment component 2 includes: Adjustment shaft 21, which is fixedly installed on the main support 1, can be a support structure that forms a rigid connection with the main support 1, and can be equipped with rolling bearings; The swing disk 22 is configured in a semi-circular structure. The swing disk 22 is mounted on the adjusting shaft 21 in a swingable manner, and the adjusting shaft 21 is located at the geometric center of the swing disk 22 to prevent the swing disk 22 from rotating eccentrically when it swings. When it is necessary to adjust the position of the grinding component 3, the operator can push the swing disk 22 to rotate around the adjustment shaft 21, causing the grinding component 3 installed on it to shift as a whole, thereby changing the position of the grinding component 3 relative to the main support 1, so that the grinding component 3 is closer to the target working area.

[0029] In this embodiment, a connecting plate 23 is provided on both sides of the swing disk 22, and the connecting plate 23 is used to install and connect the grinding assembly 3.

[0030] The connecting plate 23 refers to the plate-like structure fixed on both sides of the swing disk 22, which is used to provide installation support for the grinding assembly 3. In practical applications, one end of the two connecting plates 23 is connected to a point on the grinding assembly 3, so that the swing disk 22 and the grinding assembly 3 are connected and fixed at multiple points, thereby improving the stability of the swing disk 22 and the grinding assembly 3 after assembly.

[0031] In this embodiment, as Figure 2 As shown, in one embodiment, a plurality of slots 221 are provided at the swing end of the swing disk 22; the swing disk 22 is positioned by an external positioning component being embedded in the slots 221.

[0032] The slot 221 is a U-shaped groove structure formed on the edge of the swing disk 22. Its depth can be, for example, 1-1.5 cm. It is used to form a mechanical interlock with the external positioning component. Preferably, the external positioning component can be a workpiece such as a pin that forms a mechanical interlock with the slot.

[0033] Specifically, when the swing disk 22 swings under the support of the adjusting shaft 21, the groove 221 on its edge forms different positioning positions as the swing angle changes. When it is necessary to fix the swing disk 22, the external positioning component is pushed into the target groove 221. At this time, the swing disk 22 is limited by the contact surface between the external positioning component and the groove 221 and cannot continue to swing, thereby achieving the position locking of the grinding component 3.

[0034] Specifically, the plurality of card slots 221 include a first card slot located in the middle of the swing end of the swing disk 22, a second card slot disposed on one side of the first card slot, and a third card slot disposed on the other side of the first card slot.

[0035] In this embodiment, the symmetrical distribution of the three slots 221 allows the swing disk 22 to have three fixed positions within a range of ±15°, or the symmetrical distribution of the three slots 221 allows the swing disk 22 to have three fixed positions within a range of ±30°. The positions of the three slots 221 are set according to the user's needs, and the operator can select the corresponding slot 221 to lock according to the needs.

[0036] Preferably, in this embodiment, such as Figure 2 and Figure 3 As shown, the swing adjustment assembly 2 further includes an adjustment positioning mechanism 24. The function of the adjustment positioning mechanism 24 is the same as that of the external positioning assembly. The adjustment positioning mechanism 24 is installed on the main support 1 and is used to constrain and position the swing disk 22.

[0037] Specifically, the adjustment and positioning mechanism 24 includes a fixed plate 241 and an adjusting rod 242. The adjusting rod 242 passes through the fixed plate 241 and a limit post 243 is provided at one end of the adjusting rod 242. The oscillating disk 22 is positioned by adjusting the push limit post 243 with the adjusting rod 242 until the limit post 243 is embedded in the slot 221.

[0038] The fixed plate 241 is a plate-shaped support structure that supports the movement of the adjusting rod 242. Through holes are formed on its surface for the adjusting rod 242 to pass through. The adjusting rod 242 is a transmission component used to control the displacement of the limiting post 243, specifically, it can be pushed forward or pulled out in conjunction with a handle. The limiting post 243 is a constraint component used to embed into the slot 221 for positioning.

[0039] Specifically, when the position of the grinding component 3 needs to be adjusted, the operator operates the adjusting rod 242 to drive the limiting post 243 to move. When the limiting post 243 is completely disengaged from the current slot 221, the swing disk 22 can swing freely to the target angle. At this time, the adjusting rod 242 is pushed in the opposite direction to push the limiting post 243 into the corresponding slot 221, thereby realizing the position adjustment of the grinding component 3.

[0040] In addition, the adjustment and positioning mechanism 24 also includes: The upper positioning plate 244 and the lower positioning plate 245 are mounted on the main support 1 and clamp the fixing plate 241. Limiting waist holes 246 are provided on both the upper positioning plate 244 and the lower positioning plate 245. The upper end and the lower end of the limiting post 243 are both placed in the limiting waist holes 246.

[0041] The upper positioning plate 244 and the lower positioning plate 245 refer to two parallel plate-shaped support structures, which provide a support base for clamping and installing the fixing plate 241.

[0042] Specifically, the fixed plate 241 is clamped within the space formed by the upper positioning plate 244 and the lower positioning plate 245. The adjusting rod 242 passes through the fixed plate 241 and drives the limiting post 243 to move. When the operator rotates the adjusting rod 242, the upper and lower ends of the limiting post 243 slide within the limiting waist holes 246 of the upper and lower positioning plates 245, respectively, and its range of movement is constrained by the length direction of the waist holes. For example, when it is necessary to lock the swing plate 22, the limiting post 243 slides within the waist hole to the position corresponding to the slot 221 and then embeds itself. At this time, the contact surface between the side wall of the waist hole and the limiting post 243 forms a bidirectional constraint, preventing the adjusting rod 242 from axially shifting.

[0043] Compared with existing technologies, traditional positioning mechanisms often use a single-point fixing method, which can easily cause radial sway when the adjusting rod 242 moves. However, the double support structure formed by the upper and lower positioning plates 245, combined with the bidirectional constraint of the limiting post 243 by the limiting waist hole 246, can keep the adjusting rod 242 in a vertical state during movement, avoiding movement deviation of the adjusting rod 242.

[0044] In this embodiment, as Figures 1 to 3 As shown, the grinding assembly 3 includes: The drive motor 31 and the grinding head 32 are connected to the drive end of the drive motor 31, and the grinding head 32 is a triangular prism-shaped grinding head 32. The grinding head 32 is moved by the swing adjustment component 2 so that one side of the grinding head 32 can be pressed against the lower side of the vertical wall.

[0045] Specifically, when the oscillating disk 22 oscillates around the adjusting shaft 21, the grinding head 32 undergoes overall displacement and deflection. At this time, one side of the grinding head 32 is adjusted to be in parallel contact with the vertical wall surface. During the continuous operation of the drive motor 31, this side performs continuous grinding operations on the corner area of ​​the wall in a line contact manner.

[0046] Based on the position change achieved by the grinding component 3 through the swing adjustment component 2, the problem of inconvenient operation caused by the equipment being close to the wall in the corner area is solved. One side of the triangular prism-shaped grinding head 32 can be close to the wall for grinding work, thereby enabling the operator to complete the grinding work at the base of the wall within a safe distance.

[0047] In summary, the floor grinder in this embodiment uses the swing adjustment component 2 on the main support 1 to adjust the overall position of the grinding component 3, thereby widening the overall travel path of the floor grinder. This ensures that the main support 1, which is operated by the user, maintains a reasonable distance from the wall, effectively avoiding restrictions on operating posture and collision risks. It has the advantages of significantly improving operating comfort and safety.
