Abstract
The utility model relates to a maintenance tool for pointer type meters, in particular to a pointer pulling device for pointer type meters. The utility model mainly solves the problem that the meter is damaged caused by pulling the pointer when the pointer is pulled in pointer type meter maintenance. The pointer pulling device for pointer type meters is composed of a pull nut and a rotary nail. The pull nut and the rotary nail are in screw joint. The pull nut is a steel semi-circular ring member whose opening end is a plane, the opening width is slightly larger than the diameter of the central post of the meter and smaller than the width of the pointer at the central pin column of the meter pointer. An inner screw hole is drilled on the pull nut over against the opening. The rotary nail is provided with an outer screw which is matched with the inner screw of the pull nut. The end of one side of the rotary nail is provided with a notch, which brings convenience for the rotation of a screw driver; the other end is in truncated cone shape and can be inserted into the center of the pointer of the meter. The pointer pulling device for pointer type meters can be used for maintaining pointer type pointers such as meters, clocks, etc.
Description
One, technical field
The utility model relates to a kind of pointer instrument service kit, particularly a kind of pointer instrument pointer puller.
Two, background technology
Pointer instrument, particularly pointer pressure is widely used in industrial and mining enterprises, exists a large amount of maintenances.Must be in the repair sheet timing through taking off this procedure of pointer.At present, maintenance dedicated pointer drawer for want of when getting indicator, usual method is directly to choose or get with the tweezers sled with hand.Be that opening with tweezers is placed on the both sides below the pointer center when using tweezers, hand is firmly upwards lifted the other end of tweezers then, utilizes lever principle just to take off indicator like this.But there is following defective in this method for maintaining: when sled was got indicator, forceps tips was placed on instrument and reads must damage when getting indicator and read card on the dish; Simultaneously, tweezers are monolateral exerting oneself to pointer, thereby pointer is also had damage; The more important thing is because tweezers are monolateral firmly to pointer, make to produce damage to pointer central shaft even instrument hairspring by pointer central shaft lateral force.In addition, if, can damage pointer and hairspring too with the hand pointer of directly choosing.
Three, summary of the invention
The purpose of this utility model is: a kind of pointer instrument pointer puller is provided, damages the problem of instrument when solving the maintenance pointer instrument because of the pointer of choosing.A kind of pointer instrument pointer puller, by drawing female and revolving nail two parts, draw female with revolve the oncomelania line and be connected, utilization draws mother and the relative motion of revolving nail that pointer is extracted, draw female steel semicircle cast member that is, its openend is the plane, and A/F is slightly larger than instrument newel diameter, less than the width of gauge pointer center needle post place pointer, draw female going up to bore an internal thread hole over against opening part; Revolve to nail on and be provided with external thread and draw female screw-internal thread fit, revolve nail one side end and be provided with a notch, be convenient to the screwdriver rotation, the other end is a truncated cone shape, can insert the pointer center of instrument.Fundamentally stopped when choosing gauge pointer and damaged the generation of instrument phenomenon.
Effect of the present utility model is thoroughly to have solved when the maintenance pointer instrument and damaged the instrument thing because of the gauge pointer of choosing.
Four, description of drawings
Fig. 1 is the utility model front view
Fig. 2 is the utility model right view
Among the figure: 1-mother drawn; 2-revolve nail.
Five, embodiment
A kind of pointer instrument pointer puller is consulted figure, by drawing female 1 and revolve nail 2 two parts, draws female 1 and revolve nail 2 and be threaded.Practical example, when Y-150 type pointer pressure series tensimeter, earlier tensimeter glass face shield is taken off, to draw female 1 opening to put into again from the thin end of pointer, slide into the pointer center then, to revolve the nail 2 most advanced and sophisticated pointer centers of aiming at, revolve nail 2 with screwdriver its precession is drawn female 1, drawing mother 1 to revolve nail 2 relatively moves upward, draw female 1 just pointer to be extracted, during maintenance, can not produce, guarantee when choosing pointer, not damage instrument because of the pointer of choosing causes damage to manometric pointer, dial plate, hairspring.
Claims (1)
1, a kind of pointer instrument pointer puller, it is characterized in that: form by drawing female and revolving nail two parts, draw female with revolve the oncomelania line and be connected, draw female steel semicircle cast member that is, its openend is the plane, A/F is slightly larger than instrument newel diameter, width less than gauge pointer center needle post place pointer, draw female going up to bore an internal thread hole, revolve to nail on and be provided with external thread and draw female screw-internal thread fit over against opening part, revolve nail one side end and be provided with a notch, be convenient to the screwdriver rotation, the other end is a truncated cone shape, can insert the pointer center of instrument.
