Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a novel scraper. Background Art

[0002] The scraper rod is used to scrape off the excess coating on the coating table. The existing scraper rod is usually an integrated structure, which results in that its length cannot be extended and its applicability is relatively poor.

[0003] In order to solve the above problems, people have designed a detachable scraper rod, which includes a cylindrical working portion and a rod-shaped handle portion, wherein the inner end of the handle portion is threadedly connected to the end of the working portion.

[0004] After fixing the working part, apply external force to rotate the handle. Since the handle is threadedly connected to the working part, the handle can be extended and retracted relative to the working part after rotation. It can be seen that after the length of the entire scraper is changed, its applicability can be effectively improved. However, there is a gap at the connection between the handle and the working part. During the operation of the scraper, impurities may enter the above-mentioned gap connection, resulting in poor stability. Summary of the invention

[0005] The purpose of the utility model is to provide a new scraper with high applicability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A new scraper includes a rod-shaped body, characterized in that the body includes a cylindrical working part and a rod-shaped handle, the inner end of the handle is embedded in the working part and the outer end of the handle extends out of the working part, a damping structure is provided between the inner end of the handle and the working part to increase the friction resistance between the two, and a sealing structure is provided between the middle part of the handle and the end of the working part to seal the connection between the two.

[0008] The novel scraper creatively arranges a damping structure and a sealing structure between the handle and the working part.

[0009] The damping mechanism can create a relatively large friction resistance between the handle and the working part, that is, a relatively large external force needs to be applied before the handle can be extended or retracted relative to the working part.

[0010] The sealing structure can ensure that the connection between the working part and the handle is stably sealed, thereby preventing impurities from being embedded in the gap during the operation of the scraper.

[0011] It can be seen that, since the handle is extended and retracted relative to the working part, the length of the entire scraper can be changed, thereby making it suitable for different working occasions.

[0012] In the above-mentioned new scraper, the handle includes rod segment 1 and rod segment 2, the cross section of the rod segment 2 is prismatic and the inner cavity of the working part matches the rod segment 2, the cross section of the rod segment 1 is circular, and the rod segment 2 is embedded in the working part.

[0013] Since the rod segment 2 matches the inner cavity of the working part and the cross section of the rod segment 2 is prismatic, the handle and the working part can be circumferentially fixed, but the handle can move axially relative to the working part.

[0014] In the above-mentioned novel scraper, the working part has a recessed positioning groove inside, and the damping structure is a contact strip made of rubber material, the inner side of the contact strip is embedded in the positioning groove, and the outer side of the contact strip abuts against the side of the handle.

[0015] The contact strip is always in contact with the handle, and the flexible contact strip can effectively increase the friction resistance between the handle and the working part after being pressed against the handle.

[0016] In the above-mentioned new scraper rod, the sealing structure includes a sealing ring, a pressing sleeve and a connecting seat recessed at the port of the working part. The above-mentioned sealing ring and the pressing sleeve are both sleeved on the rod section one, the outer side of the pressing sleeve is threadedly connected to the connecting seat, the above-mentioned sealing ring is tightly pressed between the connecting seat and the pressing sleeve, and the inner side of the sealing ring is against the rod section one.

[0017] After the pressing sleeve is threadedly connected to the port of the working part, the sealing ring can be tightly pressed between the connecting seat and the pressing sleeve. Since the inner side of the flexible sealing ring abuts against the rod section 1, such a structure can ultimately effectively improve the sealing performance of the connection between the handle and the working part.

[0018] In the above-mentioned novel scraper rod, the inner diameter of the pressing sleeve is larger than the outer diameter of the rod segment one, and the inner diameter of the sealing ring is smaller than the outer diameter of the rod segment one.

[0019] Such a structure can ensure that the sealing ring is in stable contact with the rod section.

[0020] At the same time, the sealing ring can be stably positioned in the working part.

[0021] In the above-mentioned novel scraper, the rod segment 1 and the rod segment 2 are an integrated structure.

[0022] This can appropriately improve the structural compactness of the scraper bar.

[0023] In the above-mentioned novel scraper, the number of the sealing rings is several, and the several sealing rings are tightly attached together.

[0024] The provision of multiple sealing rings can effectively improve stability and prevent the sealing performance from being affected by damage to a single sealing ring.

[0025] In the above-mentioned novel scraper, the number of the handles is two, and the two handles are respectively connected to the two ends of the working part.

[0026] Such a structure enables the scraper to be stably located at the coating station.

[0027] In the above-mentioned novel scraper, the middle part of the contact strip has a concave avoidance recess, and the inner ends of the two handles are both located at the avoidance recess.

[0028] The arrangement of the avoidance recess can avoid the inner end of the handle from being blocked by the contact strip, and can enable the handle to smoothly extend and retract at the working part under the action of external force.

[0029] Compared with the prior art, the handle of the novel scraper not only has appropriate friction resistance with the working part, but also the connection between the handle and the working part has good sealing performance. Therefore, after the handle is extended and retracted, the applicability of the entire scraper can be effectively improved.

[0030] At the same time, the sealing structure and the damping structure are both located between the working part and the handle. Therefore, the structure is relatively compact, not only highly stable but also highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 As shown, the new scraper includes a rod-shaped body, which includes a cylindrical working part 1 and a rod-shaped handle 2, the inner end of the handle 2 is embedded in the working part 1 and the outer end of the handle 2 extends out of the working part 1, a damping structure is provided between the inner end of the handle 2 and the working part 1 to increase the friction resistance between the two, and a sealing structure is provided between the middle part of the handle 2 and the end of the working part 1 to seal the connection between the two.

[0037] The handle 2 includes a rod segment 1 2a and a rod segment 2b. The rod segment 2b has a prismatic cross section and the inner cavity of the working part 1 matches the rod segment 2b. The rod segment 1 2a has a circular cross section and the rod segment 2b is embedded in the working part 1.

[0038] The working part 1 has a recessed positioning groove 1 a inside, and the damping structure is a contact strip 3 made of rubber material.

[0039] The sealing structure includes a sealing ring 4, a pressing sleeve 5 and a connecting seat 1b recessed at the end of the working part 1. The sealing ring 4 and the pressing sleeve 5 are both sleeved on the rod section 2a. The outer side of the pressing sleeve 5 is threadedly connected to the connecting seat 1b. The sealing ring 4 is tightly pressed between the connecting seat 1b and the pressing sleeve 5, and the inner side of the sealing ring 4 is against the rod section 2a.

[0040] The inner diameter of the pressing sleeve 5 is larger than the outer diameter of the rod segment 2a, and the inner diameter of the sealing ring 4 is smaller than the outer diameter of the rod segment 2a.
