The invention provides a device for fixing a lamp, comprising a lamp holder, a base and a fixing band, wherein the lamp holder is cylindrical, the front end of the lamp holder expands to the outside, the lamp holder is internally provided with filament teeth matched with an illumination lamp, the base is fixed at the rear end of the lamp holder, the base is a circular truncated cone and is in threaded connection with the lamp holder, a mounting hole is formed in the bottom of the base, the fixing band passes through the mounting hole to be connected with the base, and the fixing band is in stripe shape and fixes the lamp by tying a knot after bypassing a fixed object. According to the invention, since a manner of mounting with the fixing band is adopted, the device for fixing a lamp can be arranged in various occasions without limitation and is convenient and practical.

The invention discloses a coil magnetic field shielding type proximity sensor, and aims to provide the proximity sensor with high reliability, high electromagnetic compatibility and a magnetic shielding function. According to the technical scheme, an induction assembly (5) is packaged in the inlet end of a non-magnetic cylindrical shell (1), and a lead of the induction assembly penetrates througha wire passing hole of a T-shaped spring base (4) to be connected with a non-magnetic cylindrical socket (2) which is packaged at the other end of the non-magnetic cylindrical shell; a spring (7) is fixed in a sealed cavity formed by a sealing disc on the tail part of the non-magnetic cylindrical socket through an end circular disc of the T-shaped spring base; the induction assembly generates an alternating magnetic field for leading an inductive signal of the induction assembly to the non-magnetic cylindrical socket; when a metal target approaches the magnetic field and reaches the inductivedistance, a change eddy current is generated in the metal target, and a control device is triggered and controlled, so that the eddy current is processed and converted into a switching signal by a post-stage switching circuit and an amplification output circuit.

The invention discloses a test water pressure applying device for a shield tunnel structural model. An anchoring base plate is arranged between an anchoring end and an anchoring hole of an anchor cable; anchoring through holes on the anchoring hole and the anchoring base plate are inclined, and the inclined angles ensure that no inflection points are formed at hole edges when the anchor cable passes through the anchoring hole and the anchoring through holes; the outer side of the anchoring base plate is vertical to the anchoring hole; a jack base plate is arranged between the top of a jack and a jack hole; jack through holes on the jack hole and the jack base plate are inclined, and the inclined angles ensure that no inflection points are formed at hole edges when the cable passes through the jack hole and the jack through holes; and the outer side of the jack base plate is vertical to the jack hole. A tensioning angle and a tensioning gas of the anchor cable of the device are small, and additional concentrated force at a hoop beam is small so that the influence of environmental water pressure on a model tunnel structure can be actually simulated; therefore, more accurate and reliable basis can be provided for the design and construction of the shield tunnel structure, tunnel construction and operation safety can be guaranteed, and the reliability and the safety of the device are high.

The invention discloses a parallel piezoelectric micromotion platform which comprises a platform body and a moving platform. The parallel piezoelectric micromotion platform is characterized in that elastic deformation bodies are integrally arranged at four right angles between the platform body and the moving platform; each elastic deformation body comprises two oppositely-arranged convex-concavecircular arc-shaped elastic thin sheets with equal diameters and arc lengths; both ends of each circular arc-shaped elastic thin sheet are integrally connected with the internal right angle of the platform body and the external right angle of the moving platform; at least one guide hinge is arranged on at least one side surface of the moving platform; a piezoelectric ceramic actuator is fixedly arranged between the guide hinge and the inner side surface of the platform body right opposite to the guide hinge; and the transverse cross section of the guide hinge is coincided with that of the piezoelectric ceramic actuator. The parallel piezoelectric micromotion platform has the advantages that both the translational micro-displacement and the rotary micro-displacement can be realized, so that the one-dimensional, the two-dimensional and the three-dimensional micro-displacement can be conveniently realized; the parallel piezoelectric micromotion platform has high integral rigidity and natural frequency; and the installation of the displacement sensor is not limited.
