Abstract
The utility model discloses a gas meter leakproofness detects uses pair air clamper, including being used for being equipped with two movable semicircle nuts that only can reciprocate above the opening of two fixed semicircle nuts respectively through two tracheal fixed semicircle nuts of gas -pipe thread section support respectively, two activity semicircle nuts are connected by the connecting plate of cylinder promotion through one, fix the semicircle nut and are used for through screw -thread fit formation tightly to the clamp of gas -pipe thread section with activity semicircle nut. Preferred, the connecting plate is articulated with the piston rod distal end of cylinder, be formed with the guide structure through the guide post direction between fixed semicircle nut and the activity semicircle nut. The beneficial effects of the utility model are that, simple structure, clamp are tightly reliable, and just difficult formation hurts to the gas -pipe thread.
Description
Technical field
This utility model patent relates to a kind of clamping device, particularly a kind of gas meter sealing propertytest duplex air clamper.
Background technology
Gas meter is the instrument for measuring gas consumption, and metering movement is arranged in watchcase, and gas meter is connected with source of the gas and gas equipment end respectively by air inlet pipe and escape pipe. The type of attachment of the trachea of existing domestic gas meter is usually disposed as threaded, and therefore, the trachea of gas meter has external thread structure, to be connected with source of the gas and gas equipment end pipeline respectively. The sealing of gas meter watchcase not only directly affects metering accuracy, it is often more important that relate to using gas safety. For this, need to carry out sealing propertytest before gas meter dispatches from the factory. Owing to gas meter watchcase is thin-wall case structure, detection is fixing can only be selected on trachea. Existing installation way is, is set with nut in gas-pipe thread section, carries out watchcase fix by straining or compress the axially displaced mode of this nut restriction nut, to resist the thrust that sealing detection end socket his-and-hers watches hull shape becomes. Its clamping auxiliary operation is loaded down with trivial details, and easily causes gas-pipe thread and pull, particularly when two nuts screw togather position front-back staggered, especially prominent because axial limiting bearing distribution is uneven. For this reason, it may be necessary to improve further.
Summary of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, it is provided that a kind of simple in construction, reliable clamping, and gas-pipe thread is not easily formed the gas meter sealing propertytest duplex air clamper of injury.
For achieving the above object, this utility model adopts the following technical scheme that.
A kind of gas meter sealing propertytest duplex air clamper, including being respectively used to fix half round nut by two of gas-pipe thread section two tracheas of support, two overthe openings fixing half round nut are respectively equipped with only movable half round nut moving up and down, two movable half round nuts are connected by the connecting plate of cylinder-pushed by one, fix half round nut and movable half round nut for being formed the clamping to gas-pipe thread section by threaded engagement.
Adopt this utility model of preceding solution, gas meter watchcase is fastened by two semicircle nut clip of threaded engagement in gas-pipe thread section, and realized the synchronous clamping of two tracheas by cylinder and connecting plate and fix, its clamping is firmly leaned on, thus when being effectively reduced or avoid compression or sealing propertytest, the damage to gas-pipe thread.
Preferably, the piston rod distal end articulated of described connecting plate and cylinder.To form uniform pressure distribution on two activity half round nuts, it is to avoid weigh the screw thread on watchcase trachea wounded.
Preferably, described fixing is formed through the guide frame that lead leads between half round nut and movable half round nut. To avoid traveling nut dislocation to cause that on trachea, screw thread is weighed wounded, and compress reliable.
The beneficial effects of the utility model are, simple in construction, reliable clamping, and not easily gas-pipe thread are formed injury.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described, but therefore this utility model is not limited among described scope of embodiments.
Referring to Fig. 1, a kind of gas meter sealing propertytest duplex air clamper, including being respectively used to fix half round nut 1 by two of gas-pipe thread section two tracheas of support, two overthe openings fixing half round nut 1 are respectively equipped with only movable half round nut 2 moving up and down, two movable half round nuts 2 are connected by a connecting plate 4 promoted by cylinder 3, fix half round nut 1 and movable half round nut 2 for being formed the clamping to gas-pipe thread section by threaded engagement. The piston rod 3a distal end articulated of connecting plate 4 and cylinder 3; Each fixing is fixed with a lead 5 on half round nut 1, movable half round nut 2 is provided with and the pilot hole 2a of this lead 5 matched in clearance, so that fixing the guide frame being formed through lead 5 guiding between half round nut 1 and movable half round nut 2.
Lead 5 in the present embodiment also can be fixed and be located on movable half round nut 2, fixes half round nut 1 accordingly and is provided with and the pilot hole of this lead 5 matched in clearance.
Preferred embodiment of the present utility model described in detail above. Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work. Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
