Description

A kind of safe foot pin
Technical field
The utility model relates to surveying instrument appurtenance field, particularly relates to a kind of safe foot pin.
Background technology
When adopting the method for geometric leveling to measure elevation, usually can relate to the turning point for elevation transference, and need when measuring at the foot pin of turning point place setting for supporting scale.Common foot pin part of handle in the process measured easily comes off and has one's foot squashed and foot pin can be broken, and also easily by tong in the process of foot pin carrying, thus affects normally carrying out of measurement of the level, also result in harmful effect to the personal safety of operating personnel.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, provides a kind of safe foot pin, the slewing area of handle is limited to abutment surface, avoids it to come off when operator uses and causes hazard to person.
The utility model object realizes being completed by following technical scheme:
A kind of safe foot pin, comprise bearing, leg, ball-type fulcrum and handle, described leg supports described bearing, described ball-type fulcrum is fixedly connected on described abutment surface, described handle is connected to described bearing, it is characterized in that: the surface of described bearing is fixedly connected with a fixture, and described fixture connects described handle, be rotatably assorted between the two, the slewing area of described handle is defined in the surface of described bearing.
Described fixture is stator, and described stator is fixedly connected on the surface of described bearing, and described stator offers through hole, and the local of described handle is arranged in described through hole, forms between the two and is rotatably assorted.
The local of described handle is arranged in described through hole and refers to, described handle is closed-loop, and its ring body is through described through hole.
The stator of described stator to be cross section be Ω shape, described through hole is offered and is placed in the middle part of Ω shape, and the both sides fin of described through hole is connected and fixed on the surface of described bearing.
The surface of described bearing is plane, and the slewing area of described handle is defined in the straight angle mutually concordant with the surface of described bearing.
The outer profile size size of described handle meets its local when described handle is in rotation limit position and stretches out in the requirement outside described abutment surface.
The utility model has the advantages that: difficult drop-off, not tong, material are easily got, cost is lower, convenient use, easy to maintenance, safety for a long time.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the right view of Fig. 1;
Fig. 4 is that in Fig. 1, handle rotates counterclockwise the structural representation to extreme position;
Fig. 5 is the vertical view of Fig. 4;
Fig. 6 is the schematic cross-section of stator in the utility model.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in figures 1 to 6, mark 1-7 in figure to be respectively: bearing 1, leg 2, ball-type fulcrum 3, handle 4, stator 5, through hole 6, fin 7.
Embodiment: as Figure 1-3, in the present embodiment, the main part of safe foot pin is made up of bearing 1, leg 2, ball-type fulcrum 3, wherein the leg 2 three point symmetry bottom surface that is fixedly connected on bearing 1 is with by bearing 1 overhead, and the center that ball-type fulcrum 3 is fastened on bearing 1 surface is as the turning point of elevation transference when adopting the method for measurement of the level to measure elevation.Carry between the turning point of each elevation transference for the ease of foot pin, be fixedly connected with a handle 4 on bearing 1 surface by stator 5.As shown in Figure 5, the cross section of stator 5 is Ω shape, offers a through hole 6 in the middle part of it, and through hole 6 runs through the middle part of the stator 5 in Ω shape.The fin 7 of through hole 6 both sides, by being connected and fixed between the web member such as rivet, screw and bearing 1 surface, makes stator 5 be fixedly mounted on the surface of bearing 1.Handle 4 is closed-loop, and its ring body, locally through through hole 6, makes to be rotatably assorted between handle 4 and through hole 6, the rotary motion that to make handle 4 can realize with it be rotating shaft through the local of through hole 6.Surface due to bearing 1 is plane, the slewing area of handle 4 is defined to the straight angle mutually concordant with the surface of bearing 1, namely handle 4 only can rotate in the scope on bearing 1 surface, and the rotation limit position that it is suitable, counterclockwise is mutually concordant with the surface of bearing 1 respectively, as shown in Fig. 1,4.And the slewing area limiting handle 4 can be avoided coming off in the use of foot pin or the process of carrying because its slewing area is excessive having one's foot squashed, tong etc. are to the harmful effect of operating personnel's personal safety.
The present embodiment is in the specific implementation: stator 5 should consider the empty avoiding of stepping down to ball-type fulcrum 3 position in the installation site on bearing 1 surface, avoids the handle 4 be arranged on stator 5 to collide when rotating and between ball-type fulcrum 3.
Handle 4 is fastened on the surface of bearing 1 by the stator 5 as fixture, but when reality uses, also can adopt the fixture of other versions that handle 4 is fixed on the surface of bearing 1, need when the time comes handle 4 to be arranged to adaptive shape of coincideing with its structure, such as fixture is set to the fixed block that two have through or incomplete through hole, handle 4 is arranged to U-shaped, the two ends of its U-shaped wear respectively or are plugged in hole, thus handle 4 both and between fixture was rotatably assorted, be fixed on again the surface of bearing 1.
The security of handle 4 is embodied in the not tong in handling process and the these two aspects that do not have one's foot squashed, wherein tong stretches out in the requirement outside bearing 1 surface because the outer profile size size of handle 4 meets its local when handle 4 is in rotation limit position, namely as shown in Figure 2, when handle 4 is in the rotation limit position mutually concordant with bearing 1 surface, its local stretches out in the surface periphery of bearing 1, after avoiding operating personnel bearing 1 to be transported to the position of needs by handle 4, after putting down handle 4, because handle 4 is stuck in the surface of bearing 1 and the tong caused; Do not have one's foot squashed, the slewing area making to be embodied in due to handle 4 is defined in the surface of bearing 1, so when it is in rotation limit position, remains and supported by the surface of bearing 1, has one's foot squashed so also just avoid coming off that handle 4 causes because slewing area is excessive.
Although elaborate the design of the utility model object and embodiment with reference to accompanying drawing with above-described embodiment, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: the structure of stator 5; The shape etc. of handle 4, therefore do not repeat one by one at this.
