Abstract

The invention discloses an anti-slip clencher. The anti-slip clencher comprises a left body arm, a right body arm, a main shaft pin and gripping heads, and is characterized in that a gripping head groove is formed in the upper part of each gripping head, the middles of the gripping heads are mounted in the body arms through gripping head fixing pins, the lower parts of the gripping heads are placed in the body arms and can move between the side walls of the body arms and gripping head stop pins, and the gripping head fixing pins and the gripping head stop pins are arranged at the positions to meet the requirement that when the left gripping head and the right gripping head clamp metal pipes of different lengths, the stressed surfaces of the left gripping head groove and the right gripping head groove are always kept parallel; the right body arm and a right body swing arm are connected through a swing arm rotating shaft, a chain wheel and ratchet wheel set sleeves the swing arm rotating shaft and is located in the groove of the right body arm; the chain wheel and ratchet wheel set adopts an integral double-layer structure, a chain is mounted on a chain wheel, and the right body swing arm swings horizontally to drive a ratchet wheel to rotate clockwise. Owing to the design that the right body swing arm drives the ratchet wheel, labor is saved; when the gripping heads are stressed, the stressed surfaces of the two gripping head grooves are always kept parallel, so that the construction quality is guaranteed; as the gripping heads adopt the bolt-type designs, the gripping heads with the gripping head grooves of different models can be conveniently replaced.

Background technology

Floor heating industry belongs to rising industry, there is good development prospect, in the installation of floor heating, usually need metal joint to be connected with pvc pipe, the method for connection is on metal tube, overlap pvc pipe, and then metal sleeve on overlapping outside pvc pipe, metallic sheath outside construction requirement will manage tight pvc pipe, and in this work progress, mostly is with constructions such as common vices now, do not have special instrument, such Problems existing has: 1, installing wastes time and energy; 2, construction quality is not easy to ensure, and easily damages pvc pipe and metal tube.

Summary of the invention

The object of the invention is to for the problems referred to above, provide a kind of sliding clencher, the work completing metal sleeve that pvc pipe is locked that can be time saving and energy saving, can ensure construction quality in work progress simultaneously.

The present invention is achieved in that a kind of sliding clencher, comprises left main body arm, right main body arm, king-pin and chuck, and left main body arm and right main body arm pass through, together with king-pin interconnection, to it is characterized in that described chuck is divided into left chuck and right chuck; Left chuck top is provided with left collet slot, and middle part is contained in right main body arm by left chuck steady pin, and bottom to be placed in left main body arm and can be movable between left main body arm sidewall and left chuck backing pin; Right chuck top is provided with right collet slot, and middle part is contained in left main body arm by right chuck steady pin, and bottom to be placed in right main body arm and can be movable between right main body arm sidewall and right chuck backing pin;

Left chuck steady pin and right chuck backing pin are located at the two ends of king-pin on right main body arm, right chuck steady pin and left chuck backing pin are located at the two ends of king-pin on left main body arm, when the position of chuck steady pin and chuck backing pin arranges the metal tube met when left and right chuck clamping different length, the stress surface of left and right collet slot remains parallel;

Right main body arm is connected by swing arm rotating shaft with right main body swing arm, and sprocket wheel ratchet group to be enclosed within swing arm rotating shaft and to be positioned at right main body arm groove;

The double-decker that described sprocket wheel ratchet group is integrated, one deck is sprocket wheel, and one deck is ratchet; Chain is contained on sprocket wheel, and one end is fixedly connected on left main body arm, and the other end is connected to bottom right main body swing arm by chain extension spring; Tooth button is provided with in right main body swing arm below ratchet, tooth button is contained in right main body swing arm by tooth button steady pin, the crown that tooth buckles portion withstands on ratchet and plays ratchet, tooth button left end connects tooth button switch downwards by tooth button switch connecting line, and tooth button right-hand member is connected in right main body swing arm downwards by the extension spring of tooth button;

Right main body arm above ratchet is built with the chain block preventing chain releasing, and chain block is built with anti-slop serrations button, and anti-slop serrations button is connected in chain block by the anti-slop serrations button spring of top.

Its main operation principle is: be rotatably connected in the design of right main body arm lower end and right main body swing arm of sliding clencher, the rotating shaft of right main body arm and right main body swing arm arranges the sprocket wheel ratchet group of an integrative-structure, right main body swing arm is utilized to swing, promote ratchet by the tooth button in right main body swing arm to rotate clockwise, chain is strained by sprocket wheel under the drive of ratchet simultaneously, left main body arm and right main body arm are tightened up, when being tightened to a left side, when the collet slot stress surface of right chuck is clipped on metal tube and metal sleeve, chuck starts stressed, chuck will abut against on chuck backing pin, simultaneously, because chuck backing pin and chuck steady pin are arranged on rational position, the stress surface of two chuck upper fastening grooves can be made parallel all the time, continue the right main body swing arm that swings, just metal sleeve can be clamped pvc pipe, when metal sleeve is clamped on metal joint pipe, stop when right main body swing arm resistance obviously increases.Due at metal sleeve clamping pvc pipe cover in the process of metal joint pipe, ratchet is stressed large and devise the anti-slop serrations button of top, for ratchet self-locking, prevents from skidding.Chuck adopts bolt-type design, is convenient for changing the chuck with different model collet slot, to meet the construction needs for different tube diameters in work.

Beneficial effect of the present invention is: 1, adopt swing arm to drive the design of ratchet, can be laborsaving; 2, when chuck is stressed, the stress surface of left and right collet slot remains parallel, can ensure construction quality; 3, chuck adopts bolt-type design, is convenient for changing the chuck with different model collet slot.
