Abstract
The utility model discloses a fixed locking device for a cover structure of a processing machine, which is mainly applied to the devices such as opening devices of sample boxes, compressing devices of crushers, door-positioning devices of polishing machines and the like. The fixed locking device comprises a fixed upright post, a hook, a spring and a fixed plate, wherein the middle part of the hook is axially connected with the fixed upright post, the hook can move along a shaft, one end of the spring is connected with the bottom of the hook, while the other end of the spring is fixed on the fixed plate. The fixed locking device has the advantages of simple structure, lightness, reliable use, firmness, and free operation; therefore, the fixing and locking device not only has stable use effect, but also reduces the failure rate of fixed locking aspect of various device cover structures and redices the wear rate of various devices.
Description
Technical field
The utility model relates to a kind of processing mechanical apparatus field, designs the fixing and locking device of the lid structure of processing equipment especially.
Background technology
In the processing equipment field, on plurality of devices such as sample box opening device, pulverizer hold down gag, grind away gate positioner, be equipped with the fixing and locking device of lid.Pulverizer for example, the existing apparatus structure complexity that is used for compressing on the pulverizer gland, inconvenient operation, and when work,, wear and tear excessive in case compress rocking arm because vibration is violent, and wear intensity is bigger, occur easily taking off and cover phenomenon, equipment must stop, and is not only time-consuming but also require great effort, and influenced the sample preparation time.If thrust is adjusted excessive, though can not occur taking off covering phenomenon, increased operation easier greatly, use very inconvenient.China utility model patent 200420057728.X discloses a kind of pulverizer electric clamping device, it mainly is by rubbery connector being coupled together by casting die and motionless clamping motor activity, solved moving smart contradiction in the crushing process, realize that motor compresses the purpose of pulverizer lid, alleviates people's labour intensity greatly.Though this utility model has solved the problem that motor compresses the pulverizer lid, complex structure, inconvenient operation, and to consume a large amount of electric energy, not energy-conserving and environment-protective.
The utility model content
The utility model provides a kind of fixing and locking device of lid structure of processing equipment at above problem.This pulling force fixing and locking apparatus structure is simple, light, and use is reliable, firm, and operation not only has stable result of use, but also reduced the fault rate of various device aspect the pulling force fixing and locking freely, has alleviated the wear rate to various device.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of fixing and locking device of lid structure of processing equipment, comprise vertical columns, hook, spring, fixed head, the middle part of described hook is connected with the vertical columns axle, one end of described spring is connected with the bottom of hook, and the other end of spring is fixed on the fixed head.
As further optimization, handle is installed on the top of described hook.
The utility model is simple in structure, light, convenient during use, firmly, reliable, operation freely, not only have stable result of use, but also reduced the fault rate of various device aspect the pulling force fixing and locking, alleviated wear rate to various device.Be used in especially on the pulverizer, having solved pulverizer, to compress rocking arm wearing and tearing excessive, and the problem of the gland phenomenon that occurs easily coming off has reduced the pulverizer fault rate, has increased the safety coefficient of pulverizer.
Description of drawings
Fig. 1 is applied to the structural representation of the gland fixing and locking of pulverizer for the utility model.
The specific embodiment
On pulverizer, be applied as example with the fixing and locking device of the lid structure of a kind of processing equipment of the present utility model below, in conjunction with the accompanying drawings, the utility model be described in further detail.Pulling force fixing and locking device as shown in Figure 1, comprise vertical columns 2, hook 4, spring 5, fixed head 8 and handle 7, handle 7 is arranged on the top of hook 4, the middle part of hook 4 is connected by axle 10 with vertical columns 2, and hook 4 can move along axle 10, and an end of spring 5 is connected with the bottom of hook 4, the other end of spring 5 is fixed on the adjusting nut 6, adjusting nut 6 is installed on the fixed head 8, by adjusting adjusting nut 6 in the position of fixed head 8, and elastic force that can regulating spring 5.The hook-bill of hook 4 is connected with an end that compresses rocking arm 1 of pulverizer, and an other end that compresses rocking arm 1 is hinged on the holder 9, and the stage casing that compresses rocking arm 1 connects gland 3.What produce at spring 5 is under the effect of moment of initial point with axle 10, hook-bill portion at hook 4 produces a downward countertorque, apply downward elastic force to compressing rocking arm 1, compress gland 3, avoid pulverizer in the process of pulverizing because of high vibration, wearing and tearing compress rocking arm 1, the phenomenon that causes gland 3 to come off.When the pulverizer end-of-job, when opening gland 3, on handle 7, apply the rightabout power of moment that produces with spring 5, the hook-bill of hook 4 is left compress rocking arm 1 to get final product.
Adopt in the same way, the utility model can also be used for equipment such as sample box opening device, pulverizer hold down gag, grind away gate positioner, repeats no more.
Should be noted that; the exemplary illustration that this specific embodiment is just done the utility model and do not limit its protection domain; those skilled in the art can also do the change of some unsubstantialities to the utility model; shape such as middle hook changes; these change does not need can reach through creative work, still within the protection domain of this patent.
