Abstract
The utility model discloses an antiskid valve spanner is grabbed to three, its characterized in that: the three-jaw type three-jaw combined handle comprises a handle (1), a three-jaw support frame (2), a bearing bolt (3) and a center triangle (4); the three-jaw support frame (2) is positioned at the front end of the handle (1) and welded into a whole, and a central triangle (4) is arranged in the middle of the three-jaw support frame (2); the triangle of three-jaw support frame (2) all be provided with load bolt hole (2.1), every load bolt hole (2.1) on all be provided with load bolt (3). The valve handle adjusting device overcomes the defects that in the prior art, if a person is too forceful during operation, a wrench is not firmly clamped on the valve handle, so that the person is easy to slip and hurt and is very unsafe during use, and has the advantages that a user can zoom into and out of tools with corresponding sizes according to the size of a specific valve handle, the practical range is wide, and the use is simple.
Description
Technical Field
The utility model relates to mechanical tool technical field, more specifically is an antiskid valve spanner is grabbed to three more specifically.
Background
The current technique is that opening and closing operation or running into the valve operation number of times of large-scale metal valve for carrying out in trades such as metallurgy, chemical industry, electric power are few, rust in valve rod department and cause the bite, rotate the hand wheel through normal manpower this moment and just can't operate the valve, consequently need accomplish relevant operation with the help of the valve spanner of lever principle. The valve spanner commonly used at present is F type valve spanner, and the stress point has two points only, and if the power is too violent when personnel are operating, the spanner is firmly blocked on the valve hand wheel, skids easily and causes personnel's injury, and is very unsafe during the use.
Disclosure of Invention
The utility model aims to overcome the weak point of above-mentioned background art, and provide a three and grab anti-skidding valve spanner.
The utility model aims at being implemented through the following technical scheme: a three-claw anti-skid valve wrench comprises a handle, a three-claw support frame, a bearing bolt and a center triangle;
the three-jaw support frame is positioned at the front end of the handle and welded into a whole, and a central triangle is arranged in the middle of the three-jaw support frame;
the three-jaw supporting frame is characterized in that the triangle of the three-jaw supporting frame is provided with bearing bolt holes, and each bearing bolt hole is provided with a bearing bolt.
In the above technical scheme: the handle is made of hollow steel pipes, and the three-jaw support frame is made of irregular hexagons.
In the above technical scheme: the surface of the bearing bolt is provided with threads and is made of a high-strength bolt.
The utility model has the advantages of as follows: 1. the utility model discloses have very strong practicality, be the instrument that must often use in machinery field and its simple manufacture.
2. The utility model comprises a three-grab anti-skid valve wrench with one big size and two big sizes (the handle length of the three-grab anti-skid valve wrench is 900 mm, the bearing bolt adopts the bolt of M18X60, the handle length of the small wrench is 400 mm, and the bearing bolt adopts the bolt of M12X 40); if find this size is improper in specific use, the user can zoom according to the size of specific valve hand wheel and make corresponding size the instrument can, practical wide range, it is simple to use.
3. The utility model discloses in two stress point cards that two preceding load bolts formed in the spoke both sides of valve hand wheel, the stress point that hou mian load bolt formed is put in the outside of hand wheel, pulls the three stress point of spanner all even atress, if the spanner sways from top to bottom, the head of screw rod just receives the benzyl at the lower plane of valve hand wheel, plays reliable antiskid and takes off the effect.
Drawings
Fig. 1 is a top view of the present invention.
Fig. 2 is a left side view of the present invention.
Fig. 3 is a schematic view of the structure of the middle handle of the present invention.
In the figure: the handle comprises a handle 1, a three-jaw support frame 2, a force bearing bolt hole 2.1, a force bearing bolt 3 and a central triangle 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to FIGS. 1-3: a three-claw anti-skid valve wrench comprises a handle 1, a three-claw support frame 2, a force bearing bolt 3 and a central triangle 4;
the three-jaw support frame 2 is positioned at the front end of the handle 1 and welded into a whole, and a central triangle 4 is arranged in the middle of the three-jaw support frame 2;
the triangle of the three-jaw support frame 2 is provided with bearing bolt holes 2.1, and each bearing bolt hole 2.1 is provided with a bearing bolt 3 (the bearing bolt 3 is arranged in a screwing mode).
The handle 1 is made of a hollow steel pipe, and the three-jaw support frame 2 is made of an irregular hexagon; the surface of the bearing bolt 3 is provided with threads and is made of a high-strength bolt.
The utility model discloses a following use: the utility model discloses an overall structure upgrades on ordinary F type valve spanner's basis and reforms transform and come, original two point atress changes when will operate are three atress point, form a stress surface this moment, can firmly block on the hand wheel of valve, the valve spanner handle adopts hollow steel pipe to become one with it to weld, the handle internal diameter that forms by hollow steel pipe preparation is 20 millimeters, the external diameter is 24 millimeters, three claws adopt high strength bolt to constitute simultaneously, the card that its surface belt thread can be more firm takes place the condition that prevents to skid on the hand wheel, and bolt material is easy, can purchase at corresponding five metals shop, also change easily during the damage, the length of bolt can be by the thickness free adjustment of valve hand wheel. Meanwhile, a user can independently select and match a stress application rod with a proper length at the handle of the valve wrench according to the specific use condition, so that the torque is increased, the problems that the existing F-shaped valve wrench is unstable in clamping, easy to slip and insufficient in use range during use are well solved, and the valve wrench is safer and more convenient to use.
The above-mentioned parts not described in detail are prior art.
