Description

Technical Field

[0001] The utility model belongs to the technical field of C-shaped buckles, and particularly relates to a C-shaped buckle for fixing an acrylic plate casting mold. Background Technique

[0002] Acrylic sheet, also known as flat plexiglass, mainly composed of polymethyl methacrylate, has the advantages of good light transmittance, bright colors, high brightness, light weight, strong plasticity, strong impact resistance, etc., and is widely used in the fields of architecture, transportation, lighting, medical treatment, etc.

[0003] A patent with the patent authorization number CN209224346U discloses a plexiglass production mold, including a glass plate, a sealing ring, and a C-shaped clamp; wherein the sealing ring is made of an elastic material and has a circular cross-section. The sealing ring is arranged between two glass plates and is fixed around the glass plate. In this way, the space between the two glass plates is enclosed by the sealing ring to form a cavity for filling slurry. C-shaped clamps are arranged at the edges of the two glass plates to squeeze and fix, so that the sealing ring undergoes elastic deformation to achieve a sealing effect; currently, the sealing ring is fixed on the acrylic plate by iron wire. Although it is convenient to change the position of the sealing ring and the fixing plate, there will be errors and inaccurate dimensions when manually operating the length of the iron wire. Content of the Utility Model

[0004] The utility model aims at the problems existing in the prior art and proposes the following technical solutions:

[0005] A C-shaped buckle for fixing an acrylic plate casting mold includes a locking ring. A support rod is movably connected to the locking ring, and an elastic member is connected to the inner wall of the support rod. The other end of the elastic member is connected to a limiting plate, and the limiting plate is connected to the inner wall of the locking ring.

[0006] By squeezing the support rod inward, under the action of the elastic potential energy of the rotating rod and the elastic member, the support rod is moved inward towards the inner side of the locking ring. Under the action of the gap between the locking ring and the support rod, the locking ring is sleeved on the sealing ring and the acrylic plate, thereby completing the fixed installation between the sealing ring and the acrylic plate.

[0007] As a preference of the above technical solution, a first inclined surface plate is connected to the top end of the support rod, and a second inclined surface plate is connected to one end of the locking ring close to the support rod. The contact surfaces of the first inclined surface plate and the second inclined surface plate are both inclined surfaces.

[0008] Under the action of the inclined surfaces of the first inclined surface plate and the second inclined surface plate, the contact area of the abutting surface between the locking ring and the support rod is further increased. At the same time, under the action of the inclined surface design, the support rod is prevented from popping out excessively, thereby completing the fixed installation between the sealing ring and the acrylic plate.

[0009] As a preference of the above technical solution, a butting panel is connected to the top end of the first inclined panel, and a limiting convex block is connected to the side wall of the butting panel, and the limiting convex block is inserted into the inner wall of the locking ring.

[0010] Under the limiting action of the butting panel, the situation that the supporting cross bar pops out excessively is further avoided. At the same time, with the insertion action of the limiting convex block, the stable efficiency of the fixed installation between the locking ring and the supporting cross bar for the sealing ring and the acrylic plate is ensured.

[0011] As a preference of the above technical solution, a butting pad is adhesively attached to the side of the first inclined panel close to the second inclined panel.

[0012] Under the protection of the butting pad, the situation that the contact surface between the first inclined panel and the second inclined panel is damaged due to direct impact is avoided.

[0013] As a preference of the above technical solution, a protection pad is adhesively attached to the side of the butting panel close to the locking ring.

[0014] Under the protection of the protection pad, the situation that the contact surface between the butting panel and the locking ring is damaged due to direct impact is avoided.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In this application, by squeezing the supporting cross bar inward, under the action of the elastic potential energy of the rotating rod and the elastic member, after the insertion and limiting state between the limiting convex block and the locking ring is released, at this time, under the action of the gap between the first inclined panel and the second inclined panel, the sealing ring is fixed on the acrylic plate, thereby changing the situation that there are errors in the length of the manual operation of the iron wire.
