The temporary transfer device comprises a portal frame, a holding plate A, a holding plate B, a worm, a worm gear and the like, and a moving device is mounted on the portal frame. Due to the fact that the device only acts on one end of a largesteel pipe, the device is small in size, light in weight, convenient to operate and free in steering; due to the fact that the size is small and the mass is light, the occupied space is small, and thefoldable clothes hanger is convenient to store after being used. Besides, after the large steel pipe is completely wrapped by the holding plate A, the two ends of the holding plate A are equal to theoverlapped parts of the portal frame respectively, so that the two ends of the holding plate A are stressed uniformly, and the large steel pipe is effectively supported; by means of the structure, the holding plate A is not prone to deformation after being pressed by the large steel pipe for a long time, the service life of the holding plate A is prolonged, and the maintenance cost of equipment is reduced.

The invention relates to an unmanned aerial vehicle recovery damping airbag. The unmanned aerial vehicle recovery damping airbag comprises a vehicle body, airfoils and an airbag buffer device, the airfoils are fixedly mounted on the vehicle body, and the airbag buffer device is mounted on the vehicle body and comprises a collection box, an air inlet and outlet pipeline, an air inlet fan and an airbag body. The unmanned aerial vehicle recovery damping airbag is specifically structurally characterized in that the collection box with a lower opening is fixedly mounted on one airfoil, the air inlet and outlet pipeline is mounted between the collection box and the vehicle body, one end of the air inlet and outlet pipeline is connected with the air inlet fan fixedly mounted on the vehicle body, and the other end of the air inlet and outlet pipeline extends into the collection box and is hermetically connected with the airbag body folded in the collection box. The airbag comprises an inflatable bag body made of inelastic, soft and airtight materials, and the airbag buffer device can not only absorb and release sufficient impact energy and reduce landing impact load of an unmanned aerial vehicle, but also avoid rebound during landing, so that the unmanned aerial vehicle can descend and ground stably during landing and lands safely.

The invention belongs to the technical field of medical apparatus and instruments, in particular to a nuclear medical X-ray machine. The nuclear medical X-ray machine comprises a support, a 238Pu low-energy photon source, a 241Am low-energy photon source, an anti-scattering screen, a shielding protection plate, a photographic film holder, an examination bed, a programmable control type operating table, a storage battery pack, a DC low-voltage power supply and the like, wherein the two low-energy photon sources are complementary. The nuclear medical X-ray machine provides marking X-ray or single-color X-ray radiation rather than the continuous X-ray spectrum of bremsstrahlung of the traditional X-ray machine to diagnose human organs, and the nuclear medical X-ray machine can form a high-contrast sharp image on a photographic film. The invention overcomes the defect that the dose commitment of examinees and X-ray workers is aggravated because the traditional X-ray machine and the CT (Computed Tomography) machine have diagnosis radiation and scattering radiation on non-examined human organs and can save about 90% of electric energy. The invention has the advantages of clear imaging, low energy consumption, safety, small size, light weight and the like.

The invention relates to the technical field of vehicle locks, in particular to an electric intelligent lock and a riding bicycle with the electric intelligent lock. The electric intelligent lock comprises a lock shell, a first lock rod, a second lock rod and a motor fixed in the lock shell. The outer end of the first lock rod is provided with a first spring bolt part, and the inner end of the first lock rod is provided with a first lock handle part. The outer end of the second lock rod is provided with a second spring bolt part, and the inner end of the second lock rod is provided with a second lock handle part. The first lock handle part and the second lock handle part are located in the lock shell, and the first spring bolt part and the second spring bolt part stretch out to the outer portion of the lock shell. The first spring bolt part and the second spring bolt part are mutually oppositely arranged. The motor is utilized for driving the first lock handle part and the second lockhandle part to oppositely get close to each other or get away from each other through a transmission mechanism at the same time, the first spring bolt part and the second spring bolt part do the opposite closing or opening displacement movement, and accordingly, the intelligent lock can be automatically opened and closed. Meanwhile, the structure is simple and compact, few components are needed, the fault rate is low, the size is small, the weight is small, and cost is low.

The invention discloses a rotary folding environmental friendly repeatedly fruit protector during growth. The rotary folding environmental friendly repeatedly fruit protector during growth is characterized by comprising at least six arc support rods and two arc side edges, upper portions of the support rods and the arc side edges are hinged together, lower portions of the arc support rods and the arc side edges are hinged together, the two arc side edges can rotate along the hinge joint to get close, the two arc side edges can clamped together through a buckle, contact faces of the two arc side edges are provided with rubber sealing strips, the arc support rods can rotate along the hinge joint and are distributed at equal intervals, a foldable film connected with the arc support rods and the arc side edges covers around the arc support rods and the arc side edges to form a ball like chamber, and one edge of the two side edges is provided with a fruit stem hole. The rotary folding environmental friendly repeatedly fruit protector during growth is simple and quickly in mounting process, hard to deform and damage, can be repeatedly used for many times, the average cost is reduced while the energy consumption is reduced, and the protector is better in environmental protection.

The invention relates to an on-site standard current transformer integrated device, for resolving the problems of the prior art such as disorder wiring, low safety, difficult motion, narrow detection range and low efficiency, which comprises a multi-ratio main current transformer (1) and a single-ratio auxiliary current transformer (2) for converting the secondary coil 5A of the current transformer into 1A cascade which are arranged at the left of a frame in a shell (7), and a current booster (6) at the right of the frame in the shell (7), wherein the hole of the annular iron core of the multi-ratio main current transformer (1) is opposite to the hole of the annular iron core of the current booster (6), the horizontal distance between the multi-ratio main current transformer (1) and the current booster (6) is 100 to 200mm, a front panel (4) is arranged between the multi-ratio main current transformer (1) and the current booster (6) and is provided with a through hole. The on-site standard current transformer integrated device has high integrality and fast on-site detection.

The invention belongs to the field of large-scale steel pipe transportation, and particularly relates to a large-scale steel pipe temporary transfer device for construction, which includes a door frame, a holding board A, a holding board B, a worm and a worm wheel, etc., wherein a moving device is installed on the door frame; the present invention Because it only acts on one end of the large steel pipe, it is small in size and light in weight, easy to operate, and free to turn; because it is small in size and light in weight, the space occupied by the present invention is small, and it is convenient after the use of the present invention Collection and safekeeping. In addition, after the holding plate A completely covers the large steel pipe, the two ends of the holding plate A are equal to the overlapping parts of the door frame, so that the force on both ends of the holding plate A is even, and it forms an effective support for the large steel pipe; this structure The holding plate A is not easily deformed under the long-term pressure of the large steel pipe, the service life of the holding plate A is prolonged, and the maintenance cost of the equipment is reduced.
