After the metal product is manufactured, the performance of the metal product needs to be detected. For a product in a high-temperature state in a normal working environment for a long time, heat resistance detection needs to be carried out on the product. Generally, a product is placed in a sealed box and heated for a long time by supplying high-temperature air into the box. Some products need to be supplied with oil when detecting, and in order to simulate the normal work of the products, the products need to be supplied with oil when detecting the products. If oil pipe is directly fixed to wear to establish on the box, when the oil circuit junction butt joint of oil pipe and product, because oil pipe and box are fixed, the position of oil pipe is difficult for adjusting, and the connection precision requirement between oil pipe and the product is higher, and the connection process is complicated difficult, seriously influences detection efficiency.

In order to solve the above problem, the embodiment of the utility model provides a pipeline connecting structure for oil pipe and 1 inside being connected of box, including connecting pipe 2, fixed plate 3 and elastic connecting piece, elastic connecting piece partly is connected with fixed plate 3 respectively, and elastic connecting piece another part is connected with the lateral wall that reaches box 1, has seted up the through-hole on the fixed plate 3, and mounting hole 101 has been seted up to the lateral wall of box 1, and connecting pipe 2 is suitable for wearing to locate through-hole and mounting hole 101.

Referring to fig. 1 to 3, in which a connection structure of pipes is used for connection of oil pipes outside a case 1 and products inside the case 1. Comprises a connecting pipe 2, a fixing plate 3 and an elastic connecting piece. The side wall of the box body 1 is provided with a mounting hole 101, the aperture of the mounting hole 101 is larger than the outer diameter of the connecting pipe 2, and the connecting pipe 2 is suitable for penetrating through the mounting hole 101 and extending into the box body 1. Fixed plate 3 is square board or circular plate setting, and fixed plate 3 is the stereoplasm steel sheet, sets up the through-hole that supplies connecting pipe 2 to wear to establish on the fixed plate 3. In this embodiment, the fixing plate 3 is a circular plate, and the through hole is coaxially disposed with the fixing plate 3. Due to the through holes, the fixing plate 3 is annular. The connecting pipe 2 is suitable for being arranged on the fixing plate 3 in a penetrating way through the through hole, and the circumferential side wall of the connecting pipe 2 is fixed with the fixing plate 3 through welding. The edge that connecting pipe 2 was kept away from to fixed plate 3 is connected with the lateral wall of box 1 through elastic connection spare, and fixed plate 3 and elastic connection spare carry out the shutoff with the clearance between the pore wall of the circumference lateral wall of connecting pipe 2 and mounting hole 101, have maintained the junction sealing performance of connecting pipe 2 and box 1 lateral wall.

Referring to fig. 1-3, when the product is detected, the product inside the box body 1 is connected with one end of the connecting pipe 2 extending into the box body 1 through the flange, and the end of the connecting pipe 2 outside the box body 1 is connected with the oil pipe through the flange, so that the oil pipe conveys oil liquid into the product through the connecting pipe 2, thereby facilitating the simulation of the product and detecting the performance of the product.

By the arrangement, before product detection, products in the box body 1 need to be connected with an oil pipe outside the box body 1. The fixing plate 3 is connected with the side wall of the box body 1 through the elastic connecting piece, so that a flexible connection is formed between the fixing plate 3 and the side wall of the box body 1, and the fixing plate 3 is easy to move relative to the box body 1. Because the connecting pipe 2 is inserted into the fixing plate 3, the connecting pipe 2 is also easy to move relatively with the fixing plate 3 and the box body 1.
