Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of silica gel special-shaped pipe, and in particular to an extrusion type silica gel special-shaped pipe. BACKGROUND

[0002] Special-shaped silica gel pipe refers to a non-standard cross-section silica gel pipeline made by extrusion or molding process, and its cross-section can present irregular geometric shapes such as L-shaped, U-shaped, and multi-hole type. The typical structure is composed of an inner rubber layer, a reinforcing layer, and an outer rubber layer.

[0003] In the extrusion type special-shaped silica gel pipe with publication number CN113339600A, the inner rubber layer, the reinforcing layer, and the outer rubber layer are covered on the outside of the inner rubber layer, the reinforcing layer, and the outer rubber layer, respectively. The inner rubber layer, the reinforcing layer, and the outer rubber layer are integrated by vulcanization. The reinforcing layer is a single-layer tubular fabric or a composite structure containing multiple layers of tubular fabric. The tubular fabric is woven by a knitting machine. The inner rubber layer and the outer rubber layer are made of silicone rubber. The tubular fabric is woven by aramid fiber yarn or polyester fiber yarn.

[0004] In the existing technology, the above-mentioned application adopts an inner rubber layer, a reinforcing layer, and an outer rubber layer to form an extrusion type silica gel special-shaped pipe. When using the extrusion type silica gel special-shaped pipe, the tension of the special-shaped pipe itself is usually used to limit the surface of the extrusion pipe. However, the inserted rack cannot be limited by the limiting block, and the contraction force of the arc-shaped ring cannot be adjusted, which limits the use of the special-shaped pipe and reduces the use range of the device. Therefore, an extrusion type silica gel special-shaped pipe is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0007] The utility model discloses an extrusion type silica gel special-shaped pipe, which comprises a special-shaped pipe and a locking mechanism for fitting special-shaped pipes of different sizes.

[0008] Preferably, the locking mechanism comprises an arc-shaped ring, which is arranged on the outer surface of the silica gel round frame. One end of the arc-shaped ring is fixedly installed with a placing frame.

[0009] Preferably, the placing frame is internally provided with a slot, and the inner top of the slot is fixedly installed with a limiting block. One side of the placing frame is connected with a rotating disc through a rotating rod.

[0010] Preferably, one end of the rotating rod is fixedly installed with a limiting block, and the surface lower end of the limiting block is provided with a gear tooth, the surface front surface of the limiting block is provided with a rotating block, and the inside of the limiting block is provided with a torsion spring.

[0011] Preferably, the other end of the arc-shaped ring is fixedly installed with a gear rack, and the gear rack is matched with the slot.

[0012] Preferably, the one side inclined surface of the gear tooth of the limiting block and the one side inclined surface of the gear tooth of the gear rack have the same inclination angle and the same inclination direction.

[0013] Preferably, the other side of the gear tooth of the limiting block and the other side of the gear tooth of the gear rack are both vertical surfaces.

[0014] The utility model discloses the beneficial effect that:

[0015] The locking mechanism set by the utility model is set by the top of the special-shaped pipe being sleeved on the surface of the extrusion pipe, the inserted gear rack is limited by the limiting block, the contraction force of the arc-shaped ring is adjusted, so that the special-shaped pipe is conveniently sleeved on the extrusion pipe of different diameters, and the use universality of the device is improved.
