Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vacuum bolts, and in particular to a broken vacuum bolt. Background Art
[0002] Different customers and different parts have corresponding requirements for the torque after the bolts are installed, and during the installation process, sometimes the torque is too small and loose, or the torque is too large and the teeth are crooked. When workers install bolts, they cannot intuitively know the torque of the bolts, and must use a special torque wrench to confirm. In addition, some customers require that the bolts are suitable for installation in a vacuum environment. In a vacuum system, the gas can be quickly drawn away to ensure that the system vacuum reaches the target value. Some customers also require that the bolts cannot be directly disassembled after the parts are assembled, and the assembly bolts must be broken inside the parts after they are installed in place. This is used to prevent parts from being disassembled and copied, and to protect their own intellectual property rights. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention
[0003] The purpose of the present application is to provide a broken vacuum bolt, in which the broken nut can be broken and separated, and the fixed nut and the stud remain in the part and are not easy to disassemble, and an exhaust hole is provided to facilitate the extraction of gas to ensure the vacuum degree.
[0004] In order to achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted in the present application is: a broken vacuum bolt, characterized in that it includes a stud, a fixing nut fixedly arranged on the upper end of the stud, and a broken nut detachably connected to the upper end of the fixing nut, and the stud is provided with an exhaust hole which penetrates it axially.
[0005] As a preferred technical solution, the shape of the lower portion of the broken nut is a cone with an outer diameter gradually decreasing from top to bottom.
[0006] As a preferred technical solution, the shape of the upper portion of the broken nut is cylindrical.
[0007] As a preferred technical solution, a countersunk hole is provided on the upper portion of the broken nut.
[0008] As a preferred technical solution, the countersunk hole is hexagonal.
[0009] As a preferred technical solution, a concave surface is arranged on the upper end of the fixing nut.
[0010] As a preferred technical solution, the connection between the lower end of the breaking nut and the upper end of the fixing nut is a breaking point, and a transition arc is provided at the breaking point.
[0011] The beneficial effects of this application are:
[0012] 1) After installing the vacuum bolt in place, the worker uses a general tool to screw it to the bottom and twists off the broken nut with force, so that the vacuum bolt obtains the standard torque. The remaining fixing nuts and studs remain inside the parts and cannot be removed by non-violent means. Exhaust holes are set to facilitate the extraction of gas to ensure the vacuum degree.
[0013] 2) The lower part of the broken nut is conical and can be easily twisted off.
[0014] 3) The upper part of the broken nut is cylindrical, which makes it easy for workers to twist it off.
[0015] 4) The hexagonal countersunk hole makes it easy to tighten the vacuum bolt, so that the vacuum bolt can achieve the standard torque.
[0016] 5) After the broken nut breaks, the upper end of the fixed nut will be uneven, and setting a concave surface will be more beautiful.
[0017] 6) The transition arc makes it easy to twist off the broken nut. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0025] See also Figure 1-Figure 4 An embodiment of the present application provides a broken vacuum bolt, comprising a stud 1, a fixing nut 2 fixedly arranged at the upper end of the stud 1, and a broken nut 3 detachably connected to the upper end of the fixing nut 2, wherein the stud 1 is provided with an exhaust hole 101 penetrating the stud 1 along the axial direction, and the exhaust hole 101 penetrates the fixing nut 2 and the broken nut 3 along the axial direction, and the fixing nut 2 and the stud 1 are an integral structure.
[0026] After installing the vacuum bolt in place, the worker uses a general tool such as a wrench to screw it to the bottom and forcefully twists off the broken nut 3, so that the vacuum bolt obtains the standard torque. The remaining fixing nut 2 and stud 1 remain in the bottom hole 501 of the part 5, and cannot be removed without violent means. The exhaust hole 101 is provided to facilitate the rapid extraction of gas to ensure the vacuum degree. After twisting it off, the fixing nut 2 is in uniform contact with the bottom surface of the bottom hole 501, and the stud 1 is processed according to the customer's assembly depth and the thread specifications of the bottom hole 501.
