The utility model belongs to the technical field of power batteries, and provides a battery assembly structure which comprises a battery module, a liquid cooling plate and a box body, the plurality of battery modules are mounted in the box body to form a first-layer battery structure, the liquid cooling plate is laid on the surface of the first-layer battery structure, and finally, the plurality of battery modules are mounted on the surface of the liquid cooling plate to form a second-layer battery structure. The liquid cooling plates are located among the multiple layers of battery modules, the requirement for simultaneous heat dissipation of the upper and lower layers of battery modules is met, the transverse size of the battery pack is not affected by the design, and meanwhile the requirement for the electric quantity of the battery pack is increased; in addition, a new battery module can be used for replacing the battery module when the battery module fails, and the box body can be continuously used, so that the maintenance cost is greatly reduced; according to the utility model, the foam and the limiting strips are used, the foam can generate certain deformation after being pressed by the battery module, and the limiting strips can limit the battery module to further extrude the foam, so that the foam is prevented from losing elasticity due to excessive extrusion.

The invention provides a damping sole, and belongs to the technical field of soles. Comprising a bottom layer, a supporting layer and a damping layer, the edge of the supporting layer and the inner side of the edge of the bottom layer are fixedly sealed, the damping layer is installed between the bottom layer and the supporting layer, the damping layer comprises a plurality of deformation sections, elastic pieces and movable pipes, and the deformation sections are connected in a wavy mode; and the joint between the tops of the adjacent deformation sections is fixedly connected with the supporting layer. The shock absorption layer is arranged between the bottom layer and the supporting layer, in the using process, the weight of a human body acts on the supporting layer to enable the supporting layer to be pressed, then the corrugated deformation section in the middle is promoted to deform, the deformation extrudes the movable pipe and enables the elastic piece to deform, and through the synergistic effect of deformation of the corrugated deformation section and deformation of the elastic piece, the shock absorption effect is achieved. The high-efficiency buffering and damping effects are achieved, meanwhile, the hollow structural design effectively reduces the weight of the shoe sole while guaranteeing the performance of the shoe sole, and the light-weight design enables the shoe sole to be more comfortable and convenient to wear.

This utility model relates to the field of lining production technology and discloses a warp beam dyeing vat anti-expansion clamp, including a fabric roll body, an anti-expansion clamp surrounding the end of the fabric roll body away from the center line, warp beam barrels at both ends of the fabric roll body, and the anti-expansion clamp consisting of side baffles, upper outer clamps, and lower outer clamps. An outer baffle and an inner baffle are fixedly installed on the end of the side baffle near the warp beam barrel. This warp beam dyeing vat anti-expansion clamp attaches four upper and lower outer clamps to the upper and lower sides of the fabric roll body, respectively. The stainless steel material ensures the clamps have sufficient strength to withstand the pressure generated during the dyeing process. The "arc" structure fits snugly against the fabric roll body, tightly wrapping the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively limits the expansion of the fabric roll, preventing it from sagging due to expansion and avoiding loss of elasticity. It can also be adjusted according to the diameter and width of the dyed fabric roll.

The utility model provides a pen structure based on pulling operation and a pen refill telescopic driving structure. The pen structure based on the pulling operation comprises a pen holder, a pen refill, a pen refill driving piece and a pulling operation piece. Wherein the pen holder is provided with an inner cavity, a pen point opening and a pen tail; the refill is contained in the inner cavity in a clearance mode and located between the pen point opening and the pen tail. The refill driving piece is located between the refill and the pulling operation piece, one end of the refill driving piece is connected with the refill in a clamped mode, and the other end of the refill driving piece is connected with the pulling operation piece in an abutting mode so that when the pulling operation piece is pulled, the fixing shaft portion can drive the refill driving piece to stretch out and draw back, and accordingly the refill is driven to stretch out and draw back.
