Abstract
An end plug comprises a handle and a support, wherein threads are arranged at an excircle of the support; the end plug is characterized in that an eccentric wheel is fixed at one end of the handle; a central spindle is arranged in an inner hole of the support; a step is arranged at the lower end of the central spindle; a seal sleeve is sleeved between the step of the central spindle and the lower end face of the support; the upper end of the central spindle extends out from the support; the eccentric wheel is articulated with the upper end of the central spindle; and the eccentric wheel keeps contact with a support groove at the upper end of the support. When being used, the end plug is arranged in an orifice of a gas storage tank by through the external threads of the support; the eccentric wheel is rotated by the handle; when the central spindle moves upwardly, the seal sleeve is expanded under the action of force to seal the inner end face of the gas storage tank; when the atmospheric pressure in the gas storage tank is higher, the contact is tighter in a plug port; therefore, the plugging tightness is enhanced, both the gas tightness and the security are guaranteed when the gas storage tank is inspected, and the working time of an inspector is shortened; in addition, the end plug is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of plug, especially a kind of plug that detects the gas cylinder sealing.
Background technique
The plug of existing detection gas cylinder sealing comprises handle and bearing.Make the nut on plug and the gas cylinder flexibly connect also fastening through handle; Plug makes the stressed expansion of the rubber pad on the nut seal the exterior edge face of nut, in the airtight checkout procedure of gas cylinder, if the precision of plug is low excessively; When the gas cylinder internal pressure increases; Cause the sealing of rubber pad to descend, make detection person can't correctly judge the reason of gas cylinder leakage gas, prolonged detection person's operating time; While possibly caused plug to become flexible even flown out, so can't guarantee the sealing of gas cylinder and detection person's safety.
Summary of the invention
The utility model provides a kind of plug, can solve the gas leak phenomenon in the gas cylinder air tight test process, shortens detection person's operating time.
The technological scheme that the utility model adopts is following: a kind of plug, comprise handle and bearing, and the cylindrical of bearing is provided with screw thread; It is characterized in that: an end of handle is fixed with eccentric wheel, and a mandrel is contained in the endoporus of bearing, and the lower end of mandrel is provided with step; Be with stuffing box gland between the step of mandrel and the lower end surface of bearing; Stretch out from bearing the upper end of mandrel, and eccentric wheel is hinged on the upper end of mandrel, and eccentric wheel contacts with the support slot of bearing upper end.
Beneficial effect: during use, plug is contained in the aperture of gas cylinder through the outside thread of its bearing, rotates eccentric wheel through handle, moves on the mandrel; Make the stressed expansion of stuffing box gland, the interior edge face of shutoff gas cylinder is when the gas cylinder air pressure inside heals big; The place's applying of blocking up is tighter, strengthens the shutoff sealing, has guaranteed tightness and Security when gas cylinder detects; Shortened the inspectoral operating time, this plug is simple in structure, and is easy to operate.

Embodiment
As shown in Figure 1, a kind of plug comprises handle 1 and bearing 2, and the cylindrical of bearing 2 is provided with screw thread; One end of handle 1 is fixed with 3, mandrels 4 of eccentric wheel and is contained in the endoporus of bearing 2, and the lower end of mandrel 4 is provided with step, is with stuffing box gland 5 between the lower end surface of the step of mandrel 4 and bearing 2; Stretch out from bearing 2 upper end of mandrel 4, and eccentric wheel 3 is hinged on the upper end of mandrel 4, and eccentric wheel 3 contacts with the support slot of bearing 2 upper ends, and is as shown in Figure 2; Handle 1 horizontally rotates, and eccentric wheel 3 cooperatively interacts with bearing 2, and bearing 2 and nut are flexibly connected; Handle 1 rotates, and mandrel 4 cooperatively interacts with bearing 2, makes the two ends stressed expansion simultaneously of stuffing box gland 5.
