DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0019] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0020] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, an embodiment of the utility model is a support frame for a rubber-plastic insulation pipe combustion test, comprising a frame body 1 and a plurality of vertical poles 2, wherein the frame body 1 is provided with a first slide groove and a second slide groove 3 at the top and the bottom respectively, wherein a plurality of top sliders are slidably connected in the first slide groove, and a plurality of bottom sliders 4 are slidably connected in the second slide groove 3, wherein one end of the vertical pole 2 is connected to the top slider and the other end is connected to the bottom slider 4, and the vertical pole 2 slides on the frame body 1 through the top slider and the bottom slider 4.

[0022] The beneficial effects of such a setting are as follows: the utility model has an adjustable vertical rod structure, and the position of the vertical rod used to sleeve the rubber-plastic thermal insulation pipe is adjusted by the top slider and the bottom slider, so that rubber-plastic thermal insulation pipes of different diameters can maintain a certain distance to prevent adjacent rubber-plastic thermal insulation pipes from contacting, thereby ensuring the accuracy of the combustion test results.

[0023] It is further provided that the bottom sliding block 4 includes a rotating portion 5 , a connecting portion 6 and a sliding portion 7 , the rotating portion 5 and the connecting portion 6 are rotatably connected via a bearing, and the sliding portion 7 is located in the second sliding groove 3 .

[0024] The beneficial effects of such an arrangement are as follows: through the rotational cooperation between the rotating part and the connecting part, the vertical rod and the sliding part are controlled separately, that is, the vertical rod can rotate circumferentially and the sliding part can move laterally along the second slide groove without interfering with each other and with a high degree of freedom, which makes it convenient to adjust the position of the rubber-plastic insulation pipe and to conduct combustion tests on all sides of the rubber-plastic insulation pipe.

[0025] It is further configured that a lower slide plate 8 is provided in the second slide groove 3 , and a plurality of first elastic members 9 evenly distributed along the direction of the second slide groove 3 are provided between the lower slide plate 8 and the second slide groove 3 , and the first elastic members 9 press the lower slide plate 8 toward the lower surface of the sliding portion 7 .

[0026] The beneficial effects of such a configuration are as follows: the lower slide plate is against the sliding part under the elastic force of the first elastic member, thereby lifting the sliding part; the length of the lower slide plate is the same as that of the second slide groove and both ends are against the columns on both sides of the frame, so the lower slide plate will not move; the contact area between the sliding part and the lower slide plate is smaller than the contact area between the sliding part and the bottom surface of the second slide groove, which not only plays a buffering role but also reduces the friction of the sliding part, making it easier to move the vertical pole.

[0027] It is further provided that the lower slide plates 8 are a pair and are symmetrically distributed along the axis of the upright pole 2 .

[0028] The beneficial effect of such arrangement is as follows: the sliding part is evenly stressed, and the vertical pole is prevented from shaking left and right.

[0029] It is further configured that a limiting plate 10 extends inwardly from the opening of the second slide groove 3, and a pair of upper slides 11 with the same structure as the lower slide 8 are provided between the limiting plate 10 and the bottom slide 4, and a plurality of second elastic members 12 with the same structure as the first elastic member 9 are provided between the upper slide 11 and the limiting plate 10.

[0030] The beneficial effects of such a configuration are as follows: the sliding part is limited by the limit plate to prevent the first elastic member from lifting the sliding part too high so that it slides out of the second slide groove when the vertical pole is sleeved with a lighter rubber-plastic insulation pipe; the upper surface of the sliding part is supported by the cooperation of the upper slide plate and the second elastic member to prevent the sliding part from rising and generating friction with the limit plate to affect the sliding, and further balance the forces at the four corners of the sliding part, prevent the vertical pole from shaking, and ensure smooth sliding.

[0031] It is further configured that the lower slide plate 8 is provided with a plurality of first rollers 13 evenly distributed along the direction of the second slide groove 3, the axis of the first roller 13 is perpendicular to the axis of the vertical rod 2, and the upper slide plate 11 is provided with a plurality of second rollers 14 with the same structure as the first rollers 13, and the second rollers 14 and the first rollers 13 are respectively abutted against the upper surface and the lower surface of the sliding part 7.

[0032] The beneficial effect of such arrangement is as follows: the friction between the sliding part and the upper and lower slide plates is reduced by the first roller and the second roller, thereby helping the sliding part to slide and moving the vertical pole more labor-saving.

[0033] It is further configured that a sleeve 15 extends from the vertical rod 2, and a clamping block 16 is provided on the inner wall of the sleeve 15. The rotating part 5 is provided with a first clamping groove 17, a second clamping groove 18 and a third clamping groove 19 for the clamping block 16 to slide into in sequence. When the clamping block 16 slides into the third clamping groove 19, the sleeve 15 and the rotating part 5 are clamped.

[0034] The beneficial effects of such a configuration are as follows: when the upright pole is connected to the rotating part, the card block extends into the first card slot along the path, and then the upright pole and the rotating part rotate relative to each other, and the card block slides through the second card slot, and finally slides into the third card slot to form a card connection. Under the action of the gravity of the upright pole, the card block will not easily fall out of the third card slot. The sophisticated structure has the advantages of high connection strength and easy disassembly and assembly.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
