Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe cutting technology, specifically relating to a thermal insulation pipe cutter. Background Technology

[0002] Traditional insulated pipe cutters typically employ a structure with two vertical plates, one fixed to the base and the other sliding along a guide rail. Firstly, when cutting longer pipes, to obtain sufficient working space, the movable plate often needs to be pushed to the end edge of the guide rail. At this point, the cutter's center of gravity deviates significantly from the base support surface, creating a top-heavy and unstable state, making the entire cutter prone to tipping over under cutting pressure or accidental impact. This single movement mode also results in cumbersome operation, low positioning accuracy, and an inability to provide effective support at both ends of the pipe simultaneously, leading to pipe swaying and affecting cut quality. Utility Model Content

[0003] This invention provides a thermal insulation pipe cutter, which aims to solve the technical problem of easy tipping over in existing cutters with a single movement mode.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A thermal insulation pipe cutter includes a base plate, a front upright plate and a rear upright plate. The front upright plate has a front guide groove that penetrates through the front upright plate, and the rear upright plate has a rear guide groove that penetrates through the rear upright plate. The front guide groove and the rear guide groove correspond one-to-one.

[0006] Both the front upright plate and the rear upright plate are slidably connected to the base plate. A front locking mechanism is provided between the front upright plate and the base plate to lock the position of the front upright plate relative to the base plate. A rear locking mechanism is provided between the rear upright plate and the base plate to lock the position of the rear upright plate relative to the base plate.

[0007] A clamping cavity is formed between the front upright plate and the rear upright plate, and the width of the cavity is adjusted by adjusting the distance between the front upright plate and the rear upright plate.

[0008] In a preferred embodiment, the front locking mechanism includes a front bolt disposed on the front upright plate, and a strip groove disposed on the base plate for the front bolt to pass through. The front upright plate is locked to the base plate by at least two front bolts, and the front bolts correspond one-to-one with the strip grooves.

[0009] In a preferred embodiment, the lower end of the front upright plate is provided with a front folding plate for mounting the front bolt, and the front folding plate is provided with a front through hole through which the front bolt passes.

[0010] In a preferred embodiment, the front folding plate and the front upright plate are an integral structure, and the front folding plate is perpendicular to the front upright plate.

[0011] In a preferred embodiment, the rear locking mechanism includes a rear bolt disposed on the rear upright plate, the rear bolt passing through the strip groove, and the rear upright plate being locked to the base plate by at least two of the rear bolts, with each rear bolt corresponding to one of the strip grooves.

[0012] In a preferred embodiment, the lower end of the rear upright plate is provided with a rear folding plate for mounting the rear bolt, and the rear folding plate is provided with a rear through hole for the rear bolt to pass through.

[0013] Based on the above scheme, at least two bolts are distributed in a straight line, working together to completely restrict the vertical plate from sliding in the horizontal plane only along the direction of the groove. This ensures that the vertical plate remains perpendicular and orthogonal to the base plate after being locked, preventing any skewing. This allows the guide grooves on the front and rear vertical plates to always be precisely aligned, providing a straight path for the cutting blade or saw blade and ensuring the perpendicularity of the cut.

[0014] In a preferred embodiment, the front upright plate and the rear upright plate are arranged in parallel.

[0015] In a preferred embodiment, the front guide groove includes at least two front arc-shaped grooves with different diameters, and the rear guide groove includes at least two rear arc-shaped grooves with different diameters, with the front arc-shaped grooves and rear arc-shaped grooves of the same diameter being correspondingly arranged.

[0016] Based on the above scheme, multiple arc-shaped grooves with different diameters can be set up to meet different cutting requirements.

[0017] In a preferred embodiment, the front guide groove includes four front arc-shaped grooves of different diameters, and the rear guide groove includes four rear arc-shaped grooves of different diameters.

[0018] In a preferred embodiment, the front guide groove includes a front inclined groove, and the rear guide groove includes a rear inclined groove, with the front inclined groove and the rear inclined groove being symmetrically arranged.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention provides an insulated pipe cutter. By designing both the front and rear uprights as sliding and independently locking structures, compared to traditional solutions where only a single upright is movable, this invention allows operators to symmetrically adjust the two uprights to the center of the base plate according to the pipe width. This ensures the machine's center of gravity remains stable at the base, fundamentally eliminating the risk of tipping over during operation. Secondly, the double-sliding upright structure ensures that both sides of the insulated pipe receive effective and stable support and clamping from the uprights simultaneously. This prevents longer pipes from swaying, vibrating, or twisting during cutting due to an unstable cutter center of gravity, thus guaranteeing the perpendicularity and flatness of the cut. Finally, the operator no longer needs to use a fixed plate as a reference; they can freely and flexibly adjust the distance between the two uprights according to actual needs, achieving rapid centering and positioning, making operation simpler.

[0033] The lower end of the front upright plate 2 is provided with a front folding plate 8 for mounting the front bolt, and the front folding plate 8 is provided with a front through hole through which the front bolt passes.

[0034] The front folding plate 8 and the front upright plate 2 are an integral structure, and the front folding plate 8 is perpendicular to the front upright plate 2.

[0035] Specifically, the two front bolts are located at the left and right ends of the front side of the front upright plate 2, and the two front bolts fix the front folding plate 8 to the base plate 1, thereby installing and fixing the front upright plate 2 to the base plate 1.

[0036] The rear locking mechanism 7 includes a rear bolt disposed on the rear upright plate 3. The rear bolt passes through the strip groove 10. The rear upright plate 3 is locked to the base plate 1 by at least two of the rear bolts. The rear bolts correspond one-to-one with the strip groove 10.

[0037] The lower end of the rear upright plate 3 is provided with a rear folding plate 9 for mounting the rear bolt, and the rear folding plate 9 is provided with a rear through hole for the rear bolt to pass through.

[0038] Specifically, the front locking mechanism 6 includes two front bolts, located at the left and right ends of the front folding plate 8, respectively.
