Abstract
The utility model discloses a tooth type locking device. The tooth type locking device comprises a shaft, a fixing base, a locking buckle, a locking turning wheel and a locking sleeve, wherein the fixing base, the locking buckle, the locking turning wheel and the locking sleeve are installed on the shaft in sequence, the shaft is connected to the fixing base through a hinge pin and an opening pin, the locking buckle and the locking sleeve are connected to the shaft through threads, the locking sleeve is sleeved with the locking turning wheel, the locking buckle and the locking turning wheel are locked in a meshed mode through end face helical teeth A and end face helical teeth B, and the locking turning wheel, the locking sleeve and a spring are assembled together through a clamping spring. The tooth type locking device is simple in structure and has reliable installation locking force, no auxiliary tool is needed during locking, and a user just needs to rotate the locking turning wheel with a hand to achieve the locking effect; due to the fact that the locking buckle just moves back and forth during locking and no rotational motion is generated, the reliability of an installation position is guaranteed, the situation that an installation base body is damaged due to rotation of the locking buckle during installation is avoided, the surface quality of the base body parts is effectively guaranteed, and the service life is prolonged.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of structural member connected element, specifically relates to a kind of flute profile locking device.
Background technique
During the many structural members of machinery industry connect, conventionally need a kind of locking device that can quick-detachment to connect, and these connection parts need to have, self-locking anti-loosing, vibration proof, the control of installation coupling mechanism force are had relatively high expectations, status requirement is higher.For meeting above-mentioned requirements, in structural member connects, occurred various locking devices at present, but existing locking device mostly needs to coordinate assistant tool in use, can not directly use separately.And in use, except generation seesaws, also can produce and rotatablely move, therefore mounting point precision is poor, coupling mechanism force is unreliable, in installation process due to the rotation of locking device fragile installation matrix, thereby destroy the surface quality of matrix part, reduce working life.Therefore how to develop a kind of install coupling mechanism force reliable, there is quick-detachment, can guarantee again the locking device of positional accuracy between mounted configuration part simultaneously, be current machinery industry problem demanding prompt solution.
Model utility content
For addressing the above problem, the utility model provides a kind of flute profile locking device.
The purpose of this utility model is achieved by following technical solution.
A kind of flute profile locking device described in the utility model, comprise axle and be arranged on successively fixed base, tight locking button, locking runner and the lock sleeve on axle, described axle is connected on fixed base by bearing pin and cotter pin, described tight locking button and lock sleeve are threaded connection on axle, and locking rotaring wheeling sleeve is contained in lock sleeve outside.
Described tight locking button is provided with end face helical teeth A, and locking runner is provided with end face helical teeth B, and locking runner is by the end face helical teeth A interlock locking on end face helical teeth B and tight locking button.
Between described locking runner and lock sleeve, be provided with spring.
Described locking runner, lock sleeve and spring fit together by jump ring.
On described axle, be provided with circular groove away from fixed base one end, in circular groove, be provided with stop ring.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is simple in structure, there is reliable installation coupling mechanism force, when locking, do not need assistant tool, directly just can reach locking effect with the moving locking of hand button runner, because tight locking button in locking process only seesaws, can not produce and rotatablely move, therefore both guaranteed mounting point reliability, avoid again tight locking button in installation process to rotate damage installation matrix, effectively protect the surface quality of matrix part, improve working life, increased the interchangeability that part is installed and keeped in repair simultaneously, reduce manufacture cost, and locking torque is more stable under the effect of end tooth and spring, guarantee the Safety performance that part uses.Especially in aircraft, Ship Structure part, there is larger use advantage.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is that the B-B of Fig. 2 is to view.
In figure: 1-bearing pin, 2-fixed base, 3-cotter pin, 4-tight locking button, 5-locks runner, 6-spring, 7-lock sleeve, 8-jump ring, 9-axle, 10-stop ring, 41-end face helical teeth A, 51-end face helical teeth B.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 to Figure 3, a kind of profile of tooth locking device described in the utility model, comprise axle 9 and be arranged on successively fixed base 2, tight locking button 4, locking runner 5 and the lock sleeve 7 on axle 9, described axle 9 is connected on fixed base 2 by bearing pin 1 and cotter pin 3, described tight locking button 4 and lock sleeve 7 are threaded connection on axle 9, and locking runner 5 is sleeved on lock sleeve 7 outsides.
Described tight locking button 4 is provided with end face helical teeth A41, and locking runner 5 is provided with end face helical teeth B51, and locking runner 5 is by the end face helical teeth A41 interlock locking on end face helical teeth B51 and tight locking button 4.Adopt the technical program, after the end face helical teeth A41 on tight locking button 4 coordinates with the end face helical teeth B51 on locking runner 5, under the rotarily driving of locking runner 5, tight locking button 4 seesaws by sense of rotation, thereby plays the effect that compresses or loosen.
Between described locking runner 5 and lock sleeve 7, be provided with spring 6.
Described locking runner 5, lock sleeve 7 and spring 6 fit together by jump ring 8.
On described axle 9, be provided with circular groove (not shown) away from fixed base 2 one end, in circular groove, be provided with stop ring 10.While preventing from tightening, deviate from.
As shown in Figure 1 and Figure 2, adopt flute profile locking device of the present invention in use, coordinated and be screwed into the outside thread on uranium 9 by the internal thread on lock sleeve 7, in rotational lock runner 5, lock sleeve 7 also can rotate thereupon, under the effect of internal and external threads, moves; Stop ring 10 snaps in uranium 9 circular grooves.After part installation, twisting locking runner 5 is formed and is coordinated the rear tight locking button 4 that drives to front slide by end face helical teeth B51 and the end face helical teeth A41 of tight locking button 4 under the effect of spring, forms locking.Between uranium 9 and tight locking button 4, coordinate with flat hole by self flat axle, forming tight locking button 4 can only slide and can not rotate in front and back, and like this, end face plagiodont coordinates and just has locking functions under the effect of spring, and locking is easy to, only need the runner 5 of the moving locking of button to the right can.In the time that needs loosen, will lock after runner 5 uses pulling force backward and rotate, lock sleeve 7 drives locking runner 5 to unclamp backward, can loosen.
