Description

Technical Field

[0001] The utility model belongs to the field of latch devices, in particular to an adjustable anti-loosening latch device and a roller of a rust remover. Background Art

[0002] The latch originally used for the rust remover cover was a trapezoidal latch with a sloped surface, measuring 100mm tall, 60mm short, and 300mm long. The door frame latch hole and the cover plate latch hole were both 80mm high. The latch penetrated both the door frame latch hole and the cover plate latch hole, resulting in a tight fit between the latch and the holes. This was primarily due to the flexible connection between the latch and the rust remover drum door frame latch hole and the cover plate latch hole. As the rust remover rotated, the latch and the latch hole constantly vibrated and rubbed, and the tumbling of the material inside the rust remover drum exerted a constant impact on the cover plate, causing wear on the latch and the latch hole. This caused the latch to easily break, damage the latch fuse, and cause the latch hole to become unsoldered.

[0003] The existing technology has the following defects and deficiencies: during the rust removal process, the door frame latch holes and the cover plate latch holes often become desoldered and fall off, the latches wear out, and the latch safety falls off and is damaged. In severe cases, the entire cover plate falls off and the material is scattered all over the ground, posing a safety hazard, affecting production efficiency, and increasing maintenance costs.

Figure 2 This is a right side view of the structure of an adjustable anti-loosening latch device provided by the utility model.

[0026] In short, the basic technical solution of the utility model is briefly described as follows:

[0027] An adjustable anti-loosening latch device includes a latch body whose height is adjustable; the latch body includes a base pin 1 and an adjustment pin 2, the adjustment pin 2 is arranged above the base pin 1, the bottom end of the adjustment pin 2 is provided with a first inclined surface at a certain angle to the horizontal plane, and the top end of the corresponding base pin 1 is provided with a second inclined surface, the first inclined surface and the second inclined surface have the same inclination angle with the horizontal plane, and the adjustment pin 2 moves upward or downward to adjust the height of the latch body.

[0028] The present application provides an adjustable anti-loosening latch device, which can adjust the gap between the latch body and the hole on its outside so that the latch body fits tightly with the hole on its outside to prevent loosening. The design has a simple structure, low cost, strong scalability, and is easy to modify and promote.

[0029] The following is a detailed description of an adjustable anti-loosening latch device provided by the utility model.

[0030] like Figure 1 As shown, an adjustable anti-loosening latch device includes the latch body mentioned in the above embodiment, and the height of the latch body is adjustable to fill holes of different heights.

[0031] The latch body includes a base pin 1 and an adjustment pin 2. The base pin 1 is fixed relative to the adjustment pin 2, supporting it. The adjustment pin 2 is movable relative to the base pin 1 to adjust the height of the latch body. The adjustment pin 2 is positioned above the base pin 1. The bottom end of the adjustment pin 2 is provided with a first inclined surface at a predetermined angle to the horizontal plane, and the top end of the base pin 1 is provided with a corresponding second inclined surface. The first and second inclined surfaces have the same angle to the horizontal plane. The adjustment pin 2 can be moved upward to adjust the height of the latch body. Specifically, the adjustment pin 2 moves upward, first leaving the base pin 1, then returning to the base pin 1 according to the designed height of the latch body, thereby increasing the height of the latch body. The adjustment pin 2 moves downward, first leaving the base pin 1, then returning to the base pin 1 according to the designed height of the latch body, thereby decreasing the height of the latch body. Preferably, the top end of the adjustment pin 2 is parallel to the horizontal plane, ensuring full contact between the latch body and the hole outside the latch body, ensuring a more secure fixation. Preferably, the adjustment pin 2 is self-locking on the second inclined surface. The inclination angle range of the second inclined surface meets the self-locking angle requirement, that is, the adjustment pin 2 has a self-locking function on the second inclined surface. The inclination angle range of the second inclined surface is the same as the inclination angle range of the first inclined surface.

[0032] The base pin 1 includes a free portion 11 and a connecting portion 12. The top of the free portion 11 is configured as a second inclined surface. The adjustment pin 2 is positioned above the free portion 11, and the free portion 11 is used to support the adjustment pin 2. The free portion 11 extends upward along the second inclined surface and is fixedly connected to the lower portion of the connecting portion 12. The connecting portion 12 is cylindrical and is used to connect to the adjustment pin 2. The bottom ends of the free portion 11 and the connecting portion 12 are connected, forming a coplanar surface and parallel to the horizontal plane. Preferably, the free portion 11 and the connecting portion 12 are integrally formed.

[0033] A long through hole 122 is provided in the middle of the connecting portion 12 for adjusting the height of the latch body. The adjusting bolt 121 can be moved vertically through the long through hole 122. A threaded hole is provided at the end of the adjusting pin 2 close to the connecting portion 12. The adjusting bolt 121 passes through the long through hole 122 and is screwed together with the threaded hole of the adjusting pin 2. In one specific embodiment, the threaded hole is M16; by moving the adjusting pin 2, the height of the latch body can be changed. In one specific embodiment, the long through hole 122 is a circle, that is, a rectangle in the middle with two identical semicircles at both ends of the rectangle, such as the shape of a playground. When the adjusting pin 2 is moved upward, close to the connecting portion 12, the adjusting bolt 121 moves vertically upward along the long through hole 122, increasing the height of the latch body; when the adjusting pin 2 is moved downward, away from the connecting portion 12, the adjusting bolt 121 moves vertically downward along the long through hole 122, decreasing the height of the latch body.

[0034] During use, the adjusting pin 2 is moved and the adjusting bolt 121 is tightened so that the latch body fills the hole on the outside of the latch body. In a specific embodiment, the latch body abuts against the hole on the outside of the latch body (of course, the latch body and the hole on the outside of the latch body can also be interference fit), thereby achieving a tight fit between the latch body and the hole on the outside of the latch body. The latch body and the hole on the outside of the latch body become a whole under the action of this hard connection, thereby avoiding interaction between the latch body and the hole on the outside of the latch body, and avoiding wear and loosening of the latch body and the hole on the outside of the latch body.

[0035] In a specific embodiment, a limit block is provided at the bottom of the second inclined surface to limit the lowest position of the adjusting pin 2 to prevent the adjusting pin 2 from falling.

[0036] Furthermore, the present application provides a drum of a rust remover, wherein the door frame of the drum of the rust remover is provided with a first latch seat, a second latch seat and the above-mentioned adjustable anti-loosening latch device, the latch body of the adjustable anti-loosening latch device being installed on the drum door frame of the rust remover, the first latch seat being provided at one end of the door frame of the drum, and the second latch seat being provided at the other end of the door frame of the drum; a cover plate is provided between the first latch seat and the second latch seat, the first latch seat and the second latch seat being provided symmetrically, and the drum and the cover plate are fixed by the latch body; the first latch seat is provided with a first through hole, the second latch seat is provided with a second through hole, and the cover plate is provided with a third through hole; the first through hole, the second through hole and the third through hole are coaxially provided for installing the latch body; preferably, the hole cross-sections of the first through hole, the second through hole and the third through hole are the same; the latch body passes through the first through hole, the third through hole and the second through hole in sequence to fix the cover plate and the drum. The height of the latch body is adjustable, allowing it to abut against the inner walls of the first, second, and third through-holes, achieving a rigid connection between the roller and the cover. This prevents interaction, vibration, and friction between the roller and the cover, preventing the latch body from loosening, improving efficiency, and reducing maintenance costs. It should be noted that the side farther from the central axis of the first through-hole is considered the outer side, while the side closer to the central axis of the first through-hole is considered the inner side.

[0037] In a specific embodiment, the diameter of the first through hole is 80 mm, the diameter of the second through hole is 80 mm, and the diameter of the third through hole is 80 mm. The height of the latch in the prior art is 50 mm. There is a 30 mm gap between the latch and the first through hole, the second through hole, and the third through hole. The latch and the first through hole, the second through hole, and the third through hole cannot fit tightly. During use, the material in the drum continuously generates impact force on the cover plate, severely wearing the latch and the first through hole, the second through hole, and the third through hole, which can easily cause damage to the latch connecting the first through hole, the second through hole, and the third through hole. The latch body of the present application replaces the above-mentioned latch, and the height of the latch body is adjusted to 80 mm, so that the latch body abuts against the first through hole, the second through hole, and the third through hole, thereby achieving a hard connection between the latch body, the drum, and the cover plate, avoiding damage to the latch body and the holes outside it, and reducing maintenance costs.

[0038] The adjustable anti-loosening latch device realizes the height adjustment of the latch body. By adjusting the gap between the latch body and the hole on its outside, the latch body and the hole on its outside are tightly fitted to prevent the latch body from loosening. The device is self-locking and safe and reliable. The design has a simple structure, low cost, strong scalability, and is easy to modify and promote.

Obviously, the present invention is not limited to the details of the exemplary embodiments described above, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, it is only an example, not the only one, and the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
