Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a grinding sheet connected and adapted to a jigsaw. Background Art

[0002] With the rapid development of the woodworking and home improvement industries, the requirements for surface treatment of materials such as wood are increasing. Traditional manual sanding methods are not only inefficient but also difficult to ensure consistent sanding quality, especially when working with objects with complex contours or irregular shapes. To improve work efficiency and ensure sanding quality, a variety of electric sanding tools, such as right-angle grinders and handheld grinders, have emerged on the market. However, these tools are often designed for flat surfaces or relatively simple curved surfaces, making them inflexible when it comes to fine sanding of sides or detailed areas.

[0003] As a common electric cutting tool, jigsaws are widely used in various woodworking applications due to their compactness, portability, and ease of operation. Although primarily used for cutting, jigsaws' maneuverability and flexibility also make them suitable for multifunctional applications. In recent years, attempts have been made to modify jigsaws to achieve additional functions, including using them for sanding. However, suitable sanding pads are lacking. Therefore, this application proposes a sanding pad for jigsaws. Utility Model Content

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] The utility model provides a jigsaw grinding sheet.

[0029] In this embodiment, referring to Figure 1-4 , the jig saw grinding disc, comprising:

[0030] A connecting plate 1, wherein the connecting plate 1 has a flat plate-shaped portion 2 and a connecting portion 3 connected to the plate-shaped portion, wherein the connecting portion 3 can be adapted to be connected to an output end of a jigsaw;

[0031] a buffer block 4, wherein the buffer block 4 is connected to the plate-shaped portion;

[0032] A connecting piece 5 is provided, one side of which is connected to the buffer block 4 and the other side of which is provided with a plurality of first hook surfaces 6 for connecting to the Velcro.

[0033] In this technical solution, the connecting plate, buffer block, and connecting piece with Velcro hook are provided. The connecting plate design ensures a perfect fit with the jig saw output end, while the buffer block provides a shock-absorbing function, reducing vibration during operation and improving sanding quality. The Velcro design makes changing sanding paper quick and easy. Different types of sanding paper can be replaced to suit different working conditions.

[0034] The buffer block can be made of a material with a certain elasticity, such as a rubber block, which can play a good buffering role.

[0035] The specific usage is: Figure 4 As shown, when sanding, use the connecting part to connect to the output end of the jig saw. At the same time, connect suitable sanding paper to the connecting piece. Finally, use the jig saw to drive the sanding piece up and down to sand the side of the wooden board.

[0036] Specifically, the connecting plate is a rectangular structure, and the connecting part includes a contraction part 7 of a trapezoidal structure connected to one end of the connecting plate, a bending part 8 connected to the contraction part 7, and a connecting foot 9 connected to the bending part 8, and the connecting foot is set at 90° to the connecting plate through the bending part.

[0037] In this embodiment, the rectangular connecting plate is designed as a standard shape to facilitate manufacturing and processing. The design of the trapezoidal contraction portion, the bending portion and the connecting leg enhances the strength and stability of the connecting portion.

[0038] Specifically, boss steps 10 are provided on both sides of the connecting foot.

[0039] The boss step 10 increases the connection stability between the connecting foot and the output end of the jigsaw, thereby improving the firmness of the connection.

[0040] Specifically, the connecting plate, the buffer block and the connecting piece are bonded together by adhesive.

[0041] Using adhesive to secure the connecting plate, buffer block, and connecting piece together not only ensures a tight fit between the components, but also simplifies the assembly process and reduces production costs. The use of adhesive also avoids the additional weight and complexity that mechanical connections may bring.

[0042] Specifically, it further comprises a grinding paper 11, and one side of the grinding paper 11 has a second hook surface 12 connected to the first hook surface.

[0043] The sanding paper with the second hook surface can be easily matched with the first hook surface on the connecting piece, realizing the function of quickly changing sanding paper of different grits or types. This allows flexible selection of sanding media according to actual needs, improving work efficiency and adapting to different sanding requirements.

[0044] Specifically, a plurality of grooves 13 are provided on the upper end surface of the buffer block. The grooves 13 are arranged along the length direction of the buffer block. The connecting plate and the connecting piece are provided with bosses 14 that fit into the grooves.

[0045] The grooves on the buffer block engage with the bosses on the connecting plate and connecting piece, increasing the contact area between them. This design strengthens the connection stability and prevents relative displacement under high-intensity operation. This not only improves the rigidity of the overall structure, but also helps maintain stability and consistency during the grinding process, ensuring the grinding quality.

[0046] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
