Abstract
The utility model provides a laboratory presss from both sides with arc, it includes dead lever, left arm lock, right arm lock, left side arm lock and right arm lock are not held by the screw articulatedly, and right arm lock is connected with the dead lever, and left arm lock drum embeds has cylindric nut cover, and right arm lock drum embeds there is cylindric position sleeve, the screw rod right -hand member passes left arm lock drum, nut cover, right arm lock drum and position sleeve in proper order, screw rod left side section and nut cover threaded connection, and the screw rod right -hand member does not have the screw thread, and screw rod and position sleeve are connected to the pinhole that the spring pin passed on screw rod right -hand member head and the position sleeve, screw rod left end head is worn to the axle. This alignment clip keeps steady admittedly, difficult not hard up, slippage, the operation is simple and convenient.
Description
Technical field
This utility model relates to a kind of use for laboratory fixture, especially with regard to the arc folder of the fixing cambered surface utensil of laboratory.
Background technology
The clamp structure of current laboratory is all relatively simple, and it mainly includes clamp and fixing bar, and clamp is fixing with fixing bar to be connected, and fixing bar is connected in pallet vertical rod.Clamp includes two jig arm in left and right, intersects and is fixed by rotating shaft, rotating shaft is cased with torque spring in the middle part of two jig arm, and torque spring makes the bare terminal end of jig arm be kept closed.Additionally also having and adopt screw rod clamp structure, screw rod and jig arm are threaded connection, and screw rod are two sections of reverse threads, are realized the opening and closing of two jig arm by turn screw rod.
The fixture of said structure, when fixing utensil, there is problems in that
1, complex operation, leverages work efficiency.
2, operation effort during assembly appliance, and utensil clamping shakiness, easily loosens, slips.
3, screw rod one is thick, and one thin；Thin head and thick head all have screw thread, and are reverse threads, increase at a certain angle resistance, not easily operate when causing rotating screw rod.
4, handle place is cased with gum cover, gum cover smooth surface, and wall is thin, and skidproof effect is inconspicuous.
5, main with ferrum or kirsite bi-material for main making, during room temperature, ferrum is easy-to-rust in malaria；And kirsite is more crisp, so external force met by the clip that kirsite is made, very easily rupture.
Utility model content
It is strong that the purpose of this utility model is to provide a kind of clamping stability, use for laboratory arc folder easy and simple to handle, and concrete technical scheme is as follows:
A kind of use for laboratory arc folder, it includes fixing bar, left jig arm, right jig arm, left jig arm is hinged by screw with right jig arm end, right jig arm is connected with fixing bar, it is characterized in that: the stage casing of left jig arm and right jig arm is designed to cylindrical shape, left jig arm cylinder is built-in with columned nut sleeve, and right jig arm cylinder is built-in with columned positioning sleeve；Screw rod right-hand member sequentially passes through left jig arm cylinder, nut sleeve, right jig arm cylinder and positioning sleeve, and left section of screw rod is threadeded with nut sleeve, screw rod right-hand member non-threaded, and screw rod is connected with positioning sleeve by resilient key through the pin-and-hole in screw rod right end and positioning sleeve；Axle is through at screw rod left end head.
Above-mentioned a kind of use for laboratory arc folder, it is characterised in that: the bare terminal end of left jig arm and right jig arm all designs the gripper jaw of two arcs.
Above-mentioned a kind of use for laboratory arc folder, it is characterised in that: all it is pasted with elastomeric cushion material inside the arc bare terminal end of left jig arm and right jig arm；Except elastomeric cushion material, clamp remainder is stainless steel.
Above-mentioned a kind of use for laboratory arc folder, it is characterised in that: the elastomeric cushion material inside bare terminal end is foam.
Owing to not having screw thread on the screw rod penetrating positioning sleeve side, and the screw rod of traverse nut sleeve is provided with unidirectional screw thread, so by rotating screw rod, nut sleeve drives left jig arm sweeping action on screw rod.
The beneficial effects of the utility model:
1, foam is flexible, and utensil flexible contact, can realize seamless contact with clamper surface.
2, arc folder is made up of four paws, and utensil clamping is firm, not easily loosens, slips.
3, simple, convenient, only need to rotate screw rod can clamp.
4, adopt stainless steel precision casting, polishing processing, not easy fracture, get rusty, corrode.

Detailed description of the invention
Embodiment 1
As shown in Figures 1 to 6, a kind of use for laboratory arc folder, it includes fixing bar 8, left jig arm 2, right jig arm 1, left jig arm 2 is hinged by screw 7 with right jig arm 1 end, right jig arm is connected with fixing bar, the stage casing of left jig arm and right jig arm is designed to cylindrical shape, and left jig arm cylinder is built-in with columned nut sleeve 5, and right jig arm cylinder is built-in with columned positioning sleeve 6；Screw rod 3 right-hand member sequentially passes through left jig arm cylinder, nut sleeve 5, right jig arm cylinder and positioning sleeve 6, and left section of screw rod 3 is threadeded with nut sleeve 5, screw rod 3 right-hand member non-threaded, and screw rod is connected with positioning sleeve by resilient key 10 through the pin-and-hole in screw rod right end and positioning sleeve 6；Axle 4 is through at screw rod 3 left end head.
The bare terminal end of left jig arm 2 and right jig arm 1 all designs the gripper jaw of two arcs.Elastomeric cushion material all it is pasted with: foam 9 inside the arc bare terminal end of left jig arm 2 and right jig arm 1；Except elastomeric cushion material, clamp remainder is stainless steel.
