Description
Technical field
The utility model belongs to measurement mechanism technical field, is specifically related to a kind of mark post protective sleeve.
Background technology
Mark post a kind of measures apparatus, and it is made up of two parts---bottom portion of wooden stick and conical irony.At present in China, the annual use amount of mark post is very huge; And because the safeguard measure of bottom iron cone is improper and very easily get rusty, not only brings to operation and have a strong impact on, and cause a large amount of mark post also not use how long just being scrapped.Therefore, if can extend the service life of mark post, so building cost will effectively reduce, and can not only economize on resources, can also protection of the environment.
On the other hand, the tip due to mark post is the taper shape of irony, if nib contacts is to staff in measuring process, brings grave danger can to the safety of staff.
Utility model content
The purpose of this utility model is to provide a kind of mark post protective sleeve, and the irony conical lower section solving mark post in prior art can not be effectively protected, hold flimsy problem.
The technical scheme that the utility model adopts is: a kind of mark post protective sleeve; comprise mutually affixed and be communicated with protective sleeve Part I and protective sleeve Part II; protective sleeve Part I is the face of cylinder, and protective sleeve Part II is taper seat, and the inwall of protective sleeve Part II is provided with magnet.
Feature of the present utility model is also:
Protective sleeve Part I and protective sleeve Part II are acrylonitrile-butadiene rubber.
The beneficial effects of the utility model are: a kind of mark post protective sleeve of the present utility model, and structure is simple, easy to operate and practicality is very strong, and the irony conical lower section efficiently solving mark post in prior art can not be effectively protected, hold flimsy problem.
Accompanying drawing explanation
Fig. 1 is the main pseudosection of a kind of mark post of the utility model protective sleeve.
In figure, 1. protective sleeve Part I, 2. protective sleeve Part II, 3. magnet.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
A kind of mark post protective sleeve of the utility model; as shown in Figure 1, comprise mutually affixed and be communicated with protective sleeve Part I 1 and protective sleeve Part II 2, protective sleeve Part I 1 is the face of cylinder; protective sleeve Part II 2 is taper seat, and the inwall of protective sleeve Part II 2 is provided with magnet 3.Protective sleeve Part I 1 and protective sleeve Part II 2 are acrylonitrile-butadiene rubber.
Acrylonitrile-butadiene rubber have cheap, do not absorb water, the advantage such as high temperature resistant.The size of protective sleeve be made as slightly larger than mark post diameter about 5mm, the height of protective sleeve is higher than the height of mark post bottom tip circular cone.Produce absorption affinity between magnet 3 set on protective sleeve Part II 2 inwall and the irony circular cone of mark post, can prevent protective sleeve from coming off easily.Mark post protective sleeve of the present utility model is installed on the conical lower section of mark post, the conical base of mark post can be made to completely cut off air and wet environment, effectively prevent mark post tip to get rusty abrasion deformation; And the safety of staff can be ensured.
