The utility model discloses an improved standing balance rehabilitation training device which comprises a horizontal base, two sets of parallel resistance springs are vertically and fixedly arranged on the horizontal base, the upper end of each resistance spring is fixedly connected with a supporting pipe, and the upper portions of the two supporting pipes are fixedly connected with a table top and a handrail. A leg supporting frame is arranged between the lower middle portions of the two supporting pipes and comprises a cross beam, the cross beam is connected with the supporting pipes through guide sleeves, and jackscrews are arranged on the guide sleeves and used for fastening or loosening the guide sleeves and the supporting pipes. A rotating shaft is fixedly arranged on the outer wall of the guide sleeve in the radial direction of the guide sleeve, the cross beam is rotationally connected with the rotating shaft, a square head is arranged at the tail end of the rotating shaft, a check ring is installed on the square head in a matched mode, a threaded hole is formed in the tail end face of the rotating shaft, and a matched bolt with a rotary knob is installed in the threaded hole. According to the device, the connection reliability of the standing balance rehabilitation training device in the front-back and left-right shaking process is obviously improved.

This utility model discloses a cable laying auxiliary device, comprising: a base connected to a cable reel; a support frame rotatably connected to the base, the support frame being used to adjust the laying and winding direction of the cable; and a cable laying assembly mounted on the support frame. The cable laying assembly includes a mounting component, a cable laying wheel, and a rotating shaft. The mounting component includes two symmetrically arranged mounting units, with a mounting position formed between the two mounting units. The cable laying wheel is positioned at the mounting position and connected to the two mounting units via the rotating shaft. The cable laying wheel can rotate around the rotating shaft to assist in cable laying. This utility model utilizes the two mounting units to constrain both sides of the cable laying wheel, preventing the cable from falling off the cable laying wheel during the laying process due to its own characteristics and external disturbances, thereby reducing the number of adjustments required by construction personnel and improving construction efficiency.

The invention relates to the technical field of batteries, and discloses a modified high-nickel positive electrode material and a preparation method and application thereof, the preparation method comprises the following steps: (1) mixing a cobalt salt, an organic ligand and a solvent to obtain an MOF precursor solution; (2) dispersing a high-nickel positive electrode material in the MOF precursor solution for reaction to obtain an intermediate product; and (3) carrying out solid-phase mixing on the intermediate product and a sulfur source, and carrying out heat treatment to obtain the modified high-nickel positive electrode material, the modified high-nickel positive electrode material comprises a high-nickel positive electrode material and a composite coating layer, wherein the composite coating layer comprises cobalt sulfide and a carbon material. According to the preparation method provided by the invention, the MOF material is grown in situ on the high-nickel positive electrode material, and then the sulfur source is used for vulcanization, so that the uniform and compact composite coating layer which is firmly combined with the matrix on the nanoscale is formed on the surface of the positive electrode material, the interface stability, the thermal stability and the conductivity of the material are improved, and the electrochemical performance of the battery material is further improved.

The utility model discloses a beverage shelf structure and beverage cabinet with automatic lifting function relates to beverage cabinet technical field. Beverage shelf structure includes the thing platform, lifting mechanism, spacing component, and the thing platform is equipped with a plurality of beverage layers along the height direction, and the beverage layer includes a plurality of bottles of beverage, and the lifting mechanism is used for driving the thing platform ascending movement, and the spacing component is a plurality of blocking pieces arranged on the lifting movement path of the thing platform, and the blocking piece is used for blocking the thing platform, and when the layer number of beverage layer is invariable, is driven by the lifting mechanism and is lifted and moves. A kind of beverage shelf structure with automatic lifting function of the utility model, by setting spacing component, so that: only when the beverage on the thing platform is reduced according to layer number, the thing platform will ascend and move action, and the beverage on the thing platform will correspond to rise to facilitate access, to avoid the influence that the beverage of uppermost layer is accessed and sold.
