The utility model belongs to the technical field of cabin door hinges, and particularly relates to a new energy pure electric rear cabin door hinge which comprises a hinge base and a hinge rod body, the hinge rod body is formed by combining a straight-line-section rod body, a bent-section rod body and an inclined-section rod body, and the hinge rod body is formed through extrusion of a die-casting die. A first locking adjusting opening is formed in the surface of the linear section rod body, and a hinge groove is formed in one end of the bent section rod body. According to the new energy pure electric rear cabin door hinge, firstly, through precise design of a lubricating system, continuous lubrication of the hinge is ensured, abrasion is remarkably reduced, the service life is prolonged, and the reliability of the hinge is improved; secondly, excellent sealing performance is provided through the combination of the sealing ball and the sealing ring, leakage of lubricating oil is effectively prevented, cleanliness of the system is kept, and maintenance cost is reduced; in addition, according to the design, the environmental adaptability is improved, meanwhile, the user experience is improved, noise and vibration are reduced, and the attractiveness of the vehicle is kept.

A mouse toy used in a rodent cage, relates to the technical field of barrier environment experimental animals, comprising a pipe body, sleeves are arranged on both sides of the pipe body to meet the biting habit of mice, a portable dismounting mechanism is arranged between the pipe body and the sleeve for plug-in fixing of the pipe body and the sleeve, an escape channel is arranged in the pipe body for back-and-forth shuttling movement of the mouse, an access channel is arranged in the sleeve and communicates with the escape channel, the scheme not only improves the animal welfare of rodents in the daily feeding process, but also maximizes the reduction of investment, cost reduction and efficiency increase.

The utility model discloses a flue type waste heat boiler which comprises a swirler, a steam generator, a membrane type economizer and a hyperbolic ash bucket which are sequentially connected in the vertical direction. The swirler is provided with an air inlet pipe seat which is tangentially arranged, so that the flowing track of high-temperature furnace gas is converted into spiral rotation from top to bottom, and the high-temperature furnace gas sequentially enters the steam generator and the membrane type economizer to be subjected to dividing wall heat transfer and then is discharged; technologies such as tangential air inlet, intensified heat transfer inside and outside a heating surface, a transition annular header, cold and hot state automatic positioning, a fin serpentine tube bundle and a hyperbolic ash bucket are adopted, and the explosion-proof function is achieved; the product replaces a membrane tube water cooling wall which is continuously used by a waste heat boiler in the prior art, so that the steam generator can be integrally arranged in a flue, the heat of furnace gas is completely absorbed, the section of the flue is smaller, and the flow velocity of flue gas is improved; and the steam yield is more than one time of that of a waste heat boiler with the same capacity in the prior art.

The utility model provides a kind of convenient hand film, including hand film body and timing indicating device, hand film body is close to the one end of wrist portion and uses telescopic mouth design, and timing indicating device is set in the telescopic mouth surface of hand film body front and back face.Synchronous stretching timing indicating device when wearing hand film, and timing indicating device color-changing spun fabric is exposed in air, then it can be real-time understood hand film application time by comparing color-changing spun fabric color and standard color block, realize the simple and convenient timing of hand film application.
