Abstract

The utility model relates to a fixing device and especially relates to a surface strain sensor fixing device. The surface strain sensor fixing device includes a lower half hoop and an upper half hoop fitted with each other. The lower half hoop is in a U-shaped structure. An end of the lower half hoop is provided with a hooking buckle. One end of the upper half hoop is clamped in the hooking buckle while the other end is connected with the lower half hoop through a bolt. The key point is that a strip-shaped boss that is in parallel with an axis is arranged inside the lower half hoop and the upper half hoop and the upper surface of the boss is matched with a tip of a strain sensor. By using the surface strain sensor fixing device, the recycle and the convenient installation of the surface strain sensor can be realized.

Description

A kind of surface strain formula sensor fastening device
Technical field
The utility model relates to a kind of stationary installation, especially a kind of surface strain formula sensor fastening device.
Background technology
In civil engineering construction, surface strain formula sensor has been widely used in the strain measurement of steel construction surface or concrete structural surface, strain measurement especially for the steel construction surface, the strain value of observing sensor just can be understood the firm situation of steel construction or mixed clay structure in real time, sensor necessarily requires accurately in measuring process, the producer of production surface strain formula sensor is a lot of now, manufacturing process is also very ripe, precision own can guarantee, the installation accuracy of sensor directly influences the precision of measurement like this, the erection support that a kind of fixed surface strain gauge transducer is arranged now, its structure is the square bearing of two one, be provided with the hole of placing the sensor termination in the middle of the square bearing, the top is by three planes behind the angle of pruning, wherein two tapered planes have threaded hole to be used for the screw thread that cooperates with gib screw, the fixing ailhead chucking that relies on screw in its sensor termination; When using engineering site, in order to reach the measurement requirement, bearing must be welded on the measured object surface, reach and be rigidly connected.
1, because the said fixing sensor support base is one, use screw to screw direct fixation of sensor termination, this connection belongs to a contact, can't meet the requirements of fixedly rigidity, measures inaccurate; 2, because bearing is welded on the measured object surface, has welded bearing and can be difficult to accurate sensor installation, after sensor damages, change trouble; 3, after sense cycle finished, sensor can't be recycled.
The utility model content
The technical problems to be solved in the utility model is: a kind of recycled sensor is provided, and easy for installation, can reach a kind of surface strain formula sensor fastening device of installation accuracy.
In order to solve the above problems, a kind of surface strain formula sensor fastening device, comprise second hoop and first hoop of cooperatively interacting, described second hoop is the concave shape structure, and the one end is provided with and buckles, the other end is provided with threaded hole, described first hoop is the concave character type of back-off, one end and describedly buckle clamping, and the other end links to each other with second hoop by bolt, the inboard of described second hoop and first hoop is provided with the bar shaped boss that is parallel to the axle center, and described bar shaped boss upper surface and strain gauge transducer termination are complementary
Adopt the benefit of sensor fastening device of the present utility model to have: 1, described stationary installation is separable two parts, can realize the recycling of sensor; 2, one ends are fixed with buckling articulated manner, can reach the rigidity of connection, and an end makes and is screwed, and can regulate the fixing elasticity of sensor; 3, be provided with the bar shaped boss in the garter spring, make that sensor and stationary installation are that multiaspect contacts, make fixing more firm.
As preferred version, in order to make sensor fixing more fastening, be distributed with axial striped on the described bar shaped boss.And the curvature of the surface of contact of boss is less than the sensor termination, and the threaded hole of described first hoop is bar hole radially.
As preferred version, be connected firmly in order to buckle, be provided with axial bar shaped line buckling inboard upper wall, be provided with the turning bayonet lock with second hoop shackle portion.
As preferred version, can in the air that exposes, use for a long time for stationary installation, selected material is stainless steel.
Description of drawings
Fig. 1 is that the utility model surface strain formula sensor fastening device is installed the pre-structure synoptic diagram;
Fig. 2 is the utility model surface strain formula sensor fastening device mounting structure synoptic diagram.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified.
As depicted in figs. 1 and 2, a kind of surface strain formula sensor fastening device of the present utility model comprises second hoop 2 and first hoop 1 that cooperatively interact, and second hoop 2 is the concave shape structure, and stationary installation is separable two parts, can realize the recycling of sensor; Following garter spring 2 one ends are provided with one and buckle 22, one end of described first hoop is provided with turning bayonet lock 13 and is connected to and buckles in 22, the other end links to each other with second hoop by bolt 3, first binds round the mode that an end 13 usefulness buckle clamping and fixes, can reach the rigidity of connection, one end uses bolt 3 fixing, can regulate the fixing elasticity of sensor; The inboard of second hoop 2 and first hoop 1 is provided with the bar shaped boss 11 that is parallel to the axle center, and circle and strain gauge transducer termination that bar shaped boss 11 is formed are complementary, and sensor is that a plurality of lines contact with stationary installation, makes fixing more firm; And bar shaped boss 11 is provided with axial bar shaped tooth 23 with the surface of contact of sensor, and the curvature of the surface of contact of bar shaped boss 11 is less than the sensor termination.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
