Abstract

The utility model discloses a pressure-locked type oil dipstick, mainly comprising a handle, a dipstick rack, a dipstick belt and a hand-rocking shaft, wherein a spring and a T-shaped clamping pin are arranged in the inner cavity of the hand-rocking shaft, one end of the spring is abutted on a shaft end cover, the other end of the spring is abutted on one end of the horizontal shaft of the T-shaped clamping pin, and the other end of the horizontal shaft of the T-shaped clamping pin projects out of the end part of the hand-rocking shaft and supports a rocking handle to be inclined; a clamping groove for accommodating the vertical shaft of the T-shaped clamping pin is formed in a clamping plate; and a through hole capable of accommodating the T-shaped clamping pin to rotate is formed in a left parallel clamping plate. Due to the additional arrangement of a self-locking device, and via the arrangement of the spring and the T-shaped clamping pin in the hand-rocking shaft, a dipstick plummet is prevented from driving the dipstick belt to move downwards by virtue of the principle that the spring pushes the T-shaped clamping pin to reset, and dipstick stopping is convenient, accurate, and simple and reliable in operation; therefore, on one hand, the occurrence of an explosion accident due to the spark generated by dipstick slide and dipstick plummet collision after separating-off is avoided, and a safe guarantee is provided for a user; on the other hand, the efficiency and the accuracy during a measurement are also increased.

Description

Press the locking-type ullage rule

[technical field]

The utility model relates to a kind of measuring stick tool, particularly the pressure locking-type ullage rule of oil product liquid level height in a kind of manual measurement storage tank.

[background technology]

In the industries such as petrochemical complex, often utilize Large Oil Storage tank stores or the transporting oil products such as oil tank, tank car, when these oil products join or transmit, need to accurately measure pasta position in the storage tank with ullage rule, in order to calculate the oil volume of correspondence position.Existing oil mass chi is comprised of handle, chi frame, chi band, chi thallium, rocking handle etc. usually, in measuring process, the oil product that the operator need to adhere on the wiping chi band frequently with rag, so have frequent lower chi, propose the actions such as chi, sword iron, if this moment misoperation, slide rule will occur or get loose, chi is disconnected, thallium falls, produces the situations such as spark so that cause, not only also there is certain potential safety hazard in contaminated product, even the accidents such as oil gas blast can occur.

[summary of the invention]

The purpose of this utility model is to overcome deficiency of the prior art, and a kind of pressure locking-type ullage rule with forced locking device is provided.

The purpose of this utility model is achieved in that it mainly comprises handle, chi frame, chi band and hand axle, its improvements are: be fixed with the chi frame on the end of described handle, two parallel splints about the chi frame comprises, be fixed with a clamp in the outside of right parallel splint, one end of hand axle passes clamp and chi frame successively, be connected with the hubcap that is penetrated by the left parallel splint outside, be hinged with rocking handle on the end of the other end of hand axle; Be fixed with the chi axle on the hand axle of two parallel splint inboards, be wound with the chi band on the chi axle, the end of chi band is fixedly connected with the chi thallium; Be provided with spring and T-shaped bayonet lock in hand axle inner chamber, an end of spring is resisted against on the hubcap, and the other end is resisted against on the end of T-shaped bayonet lock transverse axis, and the other end of T-shaped bayonet lock transverse axis protrudes out the end of hand axle and rocking handle pushed up into skewed; Clamp is provided with a draw-in groove that holds T-shaped bayonet lock vertical axes; Described right parallel splint is provided with the through hole that can hold T-shaped bayonet lock rotation;

Preferably, the axial line of the through hole on the transverse axis of described T-shaped bayonet lock and this right parallel splint overlaps;

Preferably, described rocking handle is articulated in the edge of hand axial end, when with rocking handle around its jointed shaft toward hand axial compression when closing, can be with the vertical axes of T-shaped bayonet lock by in the through hole that is pressed out to right parallel splint in the draw-in groove.

Compared with prior art, the beneficial effects of the utility model are: increased forced locking device, by in hand axle, being provided with spring and T-shaped bayonet lock, utilizing spring to promote principle that T-shaped bayonet lock resets stops the chi thallium to drive the chi band to move downward, it is convenient, accurate to stop chi, and operation is simple and reliable, avoided on the one hand slide rule and the rear chi thallium collision that gets loose to produce the generation that explosion accident appears in spark, provides safe guarantee to the user; Efficient and precision when measuring have also been improved on the other hand.

Fig. 2 is structure cut-open view of the present utility model.

[embodiment]

Below in conjunction with the drawings and the specific embodiments the utility model is described further:

As depicted in figs. 1 and 2, pressure locking-type ullage rule of the present utility model includes handle 1, is fixed with the chi frame on the end of handle 1, the chi frame by about two parallel splints 21,22 form, be fixed with clamp 7 in the outside of right parallel splint 22 by two lock screws 10; One end of hand axle 8 passes clamp 7 and chi frame 2 successively, is threaded with the hubcap 81 that is penetrated by left parallel splint 21 outsides, is hinged with rocking handle 5 on the end of the other end of hand axle 8; Be fixed with chi axle 4 on the hand axle 8 of two parallel splint inboards, be wound with chi band 5 on the chi axle 4, the end of chi band 5 is fixedly connected with chi thallium 6; Wherein, the utility model is provided with locking device, has an inner chamber in described hand axle 8, be provided with a spring 82 and a T-shaped bayonet lock 9 at inner chamber, one end of spring 82 is resisted against on the hubcap 81, the other end is resisted against on the end of transverse axis 91 of T-shaped bayonet lock 9, and the other end of transverse axis 91 protrudes out the end of hand axle 8 and rocking handle 5 pushed up into skewed, makes rocking handle 5 angled in the end face of hand axle 8; Clamp 7 is provided with the draw-in groove 71 that holds T-shaped bayonet lock vertical axes 92; Right parallel splint 22 is provided with a through hole 221 centered by T-shaped bayonet lock transverse axis, and the size of through hole 221 is rotated in the inner for holding T-shaped expense 9; Described rocking handle 5 is articulated in the edge of hand axle 8 end faces, when with rocking handle 5 around its jointed shaft when hand axle 8 pressing, can be with the vertical axes 92 of T-shaped bayonet lock by in the through hole 221 that is pressed out to right parallel splint in the draw-in groove 71.

During concrete the use, when wanting rotation crank 5 so that chi thallium 6 when moving up and down, need first with the end face pressing of rocking handle 5 toward hand axle 8, so that the T-shaped bayonet lock 9 in the inner chamber is pressed toward spring 82 directions, make in the draw-in groove 71 of vertical axes 92 by clamp of T-shaped bayonet lock and withdraw from, enter in the through hole 221 of right parallel splint, at this moment, hand axle 8 can drive chi axle 4 and freely rotate, in order to propose the activities such as chi or lower chi.When stopping operating or unclamp rocking handle 5 suddenly, spring 82 automatically resets, and promotes T-shaped bayonet lock vertical axes 92 to the draw-in groove 71 of clamp, and hand axle 8 is stopped operating, and stops the tenesmus of chi thallium.
