Abstract
The utility model discloses a special spanner for assembling and disassembling a petroleum bit nozzle, which comprises a spanner body and a spanner rod. One end of the spanner body is provided with acircular through hole for sleeving the spanner rod, and the other end thereof is provided with a spanner gear; the spanner gear and a spanner gear connection column are an integrated structure. The special spanner provided by the utility model integrates the spanner gear and the spanner gear connection column into one structure through milling or other processing modes so as to improve the strength of the spanner gear, and can effectively prevent the spanner from being broken due to insufficient spanner gear strength when in use.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of special spanner that is used for the loading and unloading of oil bit nozzle.
Background technology
As depicted in figs. 1 and 2, traditional oil bit nozzle wrench comprises the wrench body that is installed on the spanner, and head center is an endoporus 6 in the wrench body, and head is provided with traditional pulling teeth 5.During use, traditional pulling teeth on the conventional spanner 5 interconnects with the nozzle contact portion, and remainder will be independent unsettled, and this structure makes the situation that spanner in use often occurs fractureing because of the undercapacity of traditional pulling teeth 5.
The utility model content
Problem to be solved in the utility model is, how a kind of novel special spanner that is used for the loading and unloading of oil bit nozzle is provided, this special spanner that is used for the loading and unloading of oil bit nozzle has advantages such as simple in structure, with low cost, and can prevent effectively that spanner from fractureing in use.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of special spanner that is used for the loading and unloading of oil bit nozzle is provided, comprise wrench body and wrenching bar, one end of wrench body is provided with the manhole that is used for the socket wrenching bar, the other end of wrench body is provided with pulling teeth, it is characterized in that the described pulling teeth on the wrench body connects cylinder by the pulling teeth that is arranged on wrench body central shaft position and interconnects; Described pulling teeth is connected cylinder with pulling teeth be an overall structure.
According to the special spanner that is used for the loading and unloading of oil bit nozzle provided by the utility model, it is characterized in that described pulling teeth is connected cylinder with pulling teeth junction is set to the circular arc syndeton.
According to the special spanner that is used for the loading and unloading of oil bit nozzle provided by the utility model, it is characterized in that described wrenching bar is riveted in the manhole of wrench body end by annular knurl.
By above-mentioned technical scheme as can be known, the special spanner that is used for the loading and unloading of oil bit nozzle provided by the utility model is connected cylinder by milling or other processing modes with pulling teeth and is an overall structure with pulling teeth, thereby improved the intensity of pulling teeth, can prevent effectively that spanner from fractureing because of the pulling teeth undercapacity in use.
Description of drawings
Fig. 1 is the front view that is used for the conventional spanner end of oil bit nozzle loading and unloading;
Fig. 2 is that enlarged drawing is looked on the right side that is used for the conventional spanner end of oil bit nozzle loading and unloading;
Fig. 3 is the front view that is used for the special spanner of oil bit nozzle loading and unloading;
Fig. 4 is that enlarged drawing is looked on the right side that is used for the special spanner end of oil bit nozzle loading and unloading.
Wherein, 1, wrenching bar; 2, wrench body; 3, pulling teeth; 4, pulling teeth connects cylinder; 5, traditional pulling teeth; 6, endoporus.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in Figure 3 and Figure 4, this special spanner that is used for the loading and unloading of oil bit nozzle comprises wrench body 2 and wrenching bar 1, one end of wrench body 2 is provided with the manhole that is used for socket wrenching bar 1, the other end of wrench body 2 is provided with pulling teeth 3, it is characterized in that the described pulling teeth 3 on the wrench body 2 connects cylinder 4 by the pulling teeth that is arranged on wrench body 2 central shaft positions and interconnects; Described pulling teeth 3 is connected cylinder 4 with pulling teeth be an overall structure.Described pulling teeth 3 is connected cylinder 4 with pulling teeth junction is set to the circular arc syndeton.Described wrenching bar 1 is riveted in the manhole of wrench body 2 ends by annular knurl.
This special spanner that is used for the loading and unloading of oil bit nozzle is connected cylinder 4 by milling or other processing modes with pulling teeth 3 and is an overall structure with pulling teeth, thereby has improved the intensity of pulling teeth 3, can prevent effectively that spanner from fractureing because of pulling teeth 3 undercapacities in use.And the pulling teeth 3 on the wrench body 2 is connected cylinder 4 with pulling teeth junction is set to arc structure can prevent effectively that stress from concentrating, avoid pulling teeth 3 stress to concentrate on heat treatment or use in crack and rupture.
Though the specific embodiment to this patent is described in detail in conjunction with the accompanying drawings, those skilled in the art do not need the protection domain that various modifications that creative work can carry out or distortion still belong to this patent in the described protection domain of this patent claims.
