Description

Technical Field

[0001] The invention relates to the field of clamps, in particular to a self-locking clamp for color steel tiles and a working method thereof. Background Art

[0002] Color steel tiles, also known as colored corrugated tiles, are made of colored coated steel plates, which are rolled and cold-bent into various corrugated plates. They are widely used in various fields such as industrial and civil buildings, warehouses, special buildings, etc. due to their light weight, high strength, rich colors, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long life, and maintenance-free.

[0003] When installing the color steel tile, a special clamp is required. The clamp body is placed on both sides of the photovoltaic track and then fastened with bolts. However, after a certain period of use, this clamp is prone to loosening, which makes it unable to hold the photovoltaic track tightly, thus shortening the service life of the color steel tile; in addition, the clamp currently used has a welded hook, which requires a high welding position accuracy. Not only is the production cost high, but also during use, it is affected by external natural forces or erosion by the external environment, and is prone to breakage, thus affecting its normal use. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a self-locking clamp for color steel tiles and a working method thereof, which solves the problems existing in the use of the clamp for color steel tiles.

[0005] Technical solution: The present invention provides a self-locking clamp for color steel tiles and a working method thereof, comprising a first clamp body, a second clamp body, a first bolt structure, and a second bolt structure. The first clamp body and the second clamp body are arranged relatively to each other and are connected by a first bolt structure and a second bolt structure arranged in parallel; wherein the first clamp body and the second clamp body have the same structure, the first clamp body comprises a limit plate, a positioning plate, and a clamping plate, and the limit plate, the positioning plate, and the clamping plate are connected in sequence; a hook is provided on the limit plate, and a first bent edge is provided on the end of the hook away from the limit plate; a small bulge and a large bulge arranged in parallel are provided on the positioning plate, and a positioning hole is also provided on the positioning plate on the other side of the small bulge away from the large bulge. When installing the color steel tile photovoltaic track, loosen the first bolt structure and the second bolt structure, and stagger the first clamp body and the second clamp body of the clamp. At this time, the vertical distance between the hooks of the first clamp body and the second clamp body is larger than the width of the photovoltaic track, so as to facilitate the insertion of the track; after moving the clamp to the specified position, adjust the relative positions of the first clamp body and the second clamp body along the direction of the photovoltaic track. At this time, the large convex bump of the first clamp body is embedded in the positioning hole of the second clamp body, and the large convex bump of the second clamp body is embedded in the positioning hole of the first clamp body. Lock the first bolt structure and the second bolt structure, and the hooks on the limit plates in the first clamp body and the second clamp body move toward each other as the bolts are locked to hold the track tightly. During the locking process, with the small bulges on the first clamp body and the second clamp body as fulcrums, there is a difference in the upper and lower gaps of the first clamp body and the second clamp body, that is, the gap above the small bulge of the first clamp body and the second clamp body is larger than the gap below the small bulge, so that the hook on the limit plate tilts in the opposite direction at a certain angle, and the first curved edge on the hook firmly holds the track, playing a self-locking role.

[0006] Furthermore, the bending angle of the first curved edge is 93°.

[0007] Furthermore, the small convex bump is set in a hemispherical shape, so that there is enough gap between the first clamp body and the second clamp body during the locking process. The hemispherical setting not only reduces the contact area, but also plays a fulcrum role.

[0008] Furthermore, the large convex bump is a conical platform, which is not only convenient for insertion into the positioning hole, but also improves positioning accuracy.

[0009] Furthermore, the positioning plate is also provided with a fixing hole and a fixing straight groove, which are arranged in parallel on the positioning plate and are located below the small convex bump and the large convex bump. When the first clamp body and the second clamp body are assembled, the setting of the fixing hole and the fixing straight groove allows the first clamp body and the second clamp body to be adjusted within a certain range along the direction of the photovoltaic track when the first bolt structure is locked.

[0010] Furthermore, a second curved edge is provided on one side of the limiting plate away from the positioning plate, and the bending angle is 90°, thereby improving the strength of the clamp.

[0011] Furthermore, the hook is formed by bending the limit plate, which not only effectively utilizes the material and reduces the loss of raw materials, but also improves the dimensional accuracy and strength of the hook.

[0012] Furthermore, the first clamp body and the second clamp body are made of zinc-aluminum-magnesium steel plate. The first clamp body and the second clamp body are directly stamped from zinc-aluminum-magnesium steel plate, which is not only more plastic than the original aluminum alloy material, but also has good corrosion resistance, can meet most environmental requirements, and has a long service life.

[0013] Further, a working method of a self-locking clamp for color steel tiles, the specific steps are as follows:

[0014] 1) During installation, first loosen the first bolt structure and the second bolt structure on the clamp, and stagger the first clamp body and the second clamp body so that the vertical distance between the hooks on the first clamp body and the second clamp body is greater than the width of the photovoltaic track;

[0015] 2) Install the first clamp body and the second clamp body on the photovoltaic track and move them to the designated position;

[0016] 3) Adjust the relative positions of the first clamp body and the second clamp body along the direction of the photovoltaic track until the large convex bulge of the first clamp body is embedded in the positioning hole of the second clamp body, and the large convex bulge of the second clamp body is embedded in the positioning hole of the first clamp body;

[0017] 4) Tighten the first bolt structure and the second bolt structure;

[0018] 5) The hooks on the limit plates in the first clamp body and the second clamp body hold the photovoltaic track tightly;

[0019] 6) Repeat this cycle and install the next color steel tile with a self-locking clamp.

[0020] It can be seen from the above technical scheme that the present invention has the following beneficial effects: 1) A small hemispherical bulge is arranged on the first clamp body and the second clamp body. During the bolt locking process, the small bulge is used as a fulcrum, so that there is a difference in the gap between the upper and lower parts, that is, the position of the limit plates of the two clamp bodies is gradually opened, and the position of the clamp plate is gradually tightened. During this process, the two hooks on the limit plates of the two clamp bodies are inclined in opposite directions, so as to firmly hold the track and play a self-locking role, thereby greatly improving its service life; 2) Corresponding large bulges and positioning holes are arranged on the first clamp body and the second clamp body, which play a positioning role during the installation process, thereby improving the accuracy of the clamping position; 3) The first clamp body and the second clamp body are directly stamped from zinc-aluminum-magnesium steel plates, which are not only more plastic than the original aluminum alloy material, but also have better corrosion resistance, which increases their service life. In addition, the hooks thereon are formed by bending from the limit plates, which not only effectively utilizes materials and reduces raw material consumption, but also improves the dimensional accuracy and strength of the hooks.
