Description

Technical Field

[0001] The utility model relates to the technical field of hand-held grinders, in particular to a hand-held grinder for processing cultural relic restoration wood. Background Art

[0002] In the field of cultural relics restoration, especially the restoration of wooden cultural relics, fine polishing is an indispensable key step. Due to their age, wooden cultural relics often have problems such as surface weathering, cracks, and corrosion. These defects need to be removed through polishing to restore their original texture and gloss. In order to be able to operate in real time, a handheld grinder is needed.

[0003] When polishing the corridors in ancient architectural cultural relics, since the top surface size of the ancient building corridor guardrails is often narrow, smaller than the grinding wheel diameter of the traditional handheld grinder, in the actual operation process, the staff needs to move the grinder carefully. Long-term work may cause hand fatigue of the staff, which will cause the grinder to tilt, resulting in uneven polishing surface, affecting the beauty and accuracy of the restoration effect. Therefore, a handheld grinder for cultural relic restoration wood processing is proposed to address the above situation. Utility Model Content

[0006] A hand-held grinder for processing wood for cultural relic restoration comprises a hand-held grinder body. Mounting seats are symmetrically arranged on the outside of the hand-held grinder body, and a pair of mounting seats are both provided with guide mechanisms.

[0007] The guide mechanism comprises a bracket connected to the mounting seat, a screw rod is threadedly connected to the bracket, a rectangular block is arranged at one end of the screw rod, three rows of cavities are opened on the side of the rectangular block away from the screw rod, and a ball is rollingly connected in each cavity.

[0008] Preferably, a slot is provided on the mounting seat, and a pair of card slots are provided on both sides of the inner surface of the slot.

[0009] Preferably, the bracket is in an "L" shape, an assembly block is provided on the bracket, and a pair of clamping blocks is provided on the assembly block.

[0010] Preferably, the assembly block is inserted into the slot, and the card block cooperates with the card slot.

[0011] Preferably, a screw hole is formed through the bracket, and the screw hole cooperates with the screw rod.

[0012] Preferably, a knob is provided at one end of the screw rod away from the rectangular block.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model adopts the structural design of the mounting seat, the bracket, the rectangular block and the ball bearing, so that when the staff operates the hand-held grinder body, it can effectively contact with both sides of the plate to form a stable support and guiding effect, thereby reducing the tilting phenomenon of the hand-held grinder body caused by improper operation, thereby ensuring the uniformity and consistency of the grinding surface and improving the quality of the repair work.

[0015] 2. The utility model makes the distance between the ball and the side of the plate adjustable through the structure of the bracket, the screw rod and the rectangular block, so that the hand-held grinder body can be used for grinding the guardrails of the ancient building corridors of different sizes, thereby enhancing its adaptability and flexibility.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A hand-held sander for wood processing for cultural relic restoration comprises a hand-held sander body 1, a mounting seat 2 is symmetrically arranged on the outside of the hand-held sander body 1, and a pair of mounting seats 2 are both provided with a guide mechanism 3.

[0023] The guide mechanism 3 includes a bracket 301 connected to the mounting seat 2, a screw rod 303 is threadedly connected to the bracket 301, a rectangular block 304 is provided at one end of the screw rod 303, and the rectangular block 304 has three rows of cavities 3040 on the side away from the screw rod 303, and a ball 305 is rollingly connected in each cavity 3040.

[0024] In the present embodiment, when the staff uses the hand-held grinder body 1 to grind structures such as the corridor of an ancient building, they first hold the bracket 301 and install it on the mounting base 2, then rotate the screw 303, and the screw 303 rotates and moves toward the side close to the corridor guardrail until the ball 305 contacts it. Similarly, the rotation of the other screw 303 is completed. After the ball 305 on a pair of rectangular blocks 304 contacts the side of the guardrail, a stable support and guiding effect is formed, which reduces the tilting phenomenon of the hand-held grinder body 1 caused by improper operation, thereby ensuring the uniformity and consistency of the grinding surface and improving the quality of the repair work.

[0025] Furthermore, by operating the screw rod 303, the distance between the ball 305 and the side of the plate can be adjusted, so that the hand-held grinder body 1 can be suitable for grinding guardrails of ancient building corridors of different sizes, thereby enhancing its adaptability and flexibility.

[0026] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, a slot 201 is provided on the mounting base 2, and a pair of card slots 202 are provided on both sides of the inner surface of the slot 201. The shape of the bracket 301 is "L"-shaped, and an assembly block 302 is provided on the bracket 301. A pair of card blocks are provided on the assembly block 302. The assembly block 302 is inserted into the slot 201, and the card block cooperates with the card slot 202.

[0027] In this embodiment, the slot 201 and the clamping slot 202 are provided, and the assembly block 302 and the clamping block are provided to complete the clamping connection between the guide mechanism 3 and the hand-held grinder body 1 .
