The utility model discloses an outdoor table top warmer convenient for adjusting the height of a table top, which relates to the technical field of outdoor tables and comprises a table top and a protective strip, and the protective strip is fixedly connected to the side of the table top and is made of an elastic material; the outdoor table top warmer facilitating table top height adjustment is provided with an adjusting structure, a driven bevel gear is driven to rotate by controlling rotation of a rotary knob, in the process, the driven bevel gear drives a lead screw to rotate in a moving block, and when the lead screw rotates in the moving block, the lead screw can rotate in the moving block, so that the height of the table top can be adjusted conveniently. According to the device, the moving block is driven to move up and down, then up-down movement of the moving block directly influences up-down movement of the moving shaft, the moving shaft is located in the two sliding grooves, the position of the intersection point of the two sliding grooves is adjusted in the moving process of the moving shaft, and therefore the included angle between the two supporting rods is changed; through the series of mechanical linkage, the height of the table top is finally adjusted.

The utility model discloses a telescopic measurable pile foundation positioning device, which belongs to the technical field of building pile foundation support construction and comprises a device main body and support legs, an inner groove is arranged in the device main body in a penetrating manner, the support legs are vertically arranged at two ends of two sides of the top of the device main body respectively, and movable grooves are arranged in two sides of two ends of the device main body respectively. Mounting clamping frames are fixed to the two sides of the front end of the device main body respectively; connectors are arranged at the bottom ends of the supporting legs; inserting grooves are formed in the supporting leg main body; telescopic rods are inserted into the inserting grooves, the top ends of the telescopic rods penetrate through the top ends of the supporting legs, and fixing rings are fixed to the top ends of the telescopic rods; and an insertion rod penetrates through the interior of the insertion opening. The device can be fixed to the construction ground through the supporting feet, the arranged supporting feet can be folded and stretched out and drawn back, the occupied space of the positioning device is reduced, and the pile foundation positioning device can be stretched out and drawn back in an auxiliary mode.

The utility model discloses a forestry pest control pesticide spraying device, which belongs to the technical field of forestry pest control and comprises a pesticide storage barrel, the surface of the pesticide storage barrel is fixedly connected with an angle adjusting component, the angle adjusting component is rotatably connected with a pesticide spraying component, and the pesticide spraying component is rotatably connected with a range adjusting component. The pesticide storage barrel can prevent pesticide effect from being reduced and pesticide cost from being increased due to the fact that pesticide is in a standing state for a long time and precipitates, meanwhile, the filtering function is achieved, river water can be directly added into the pesticide storage barrel to be sprayed, water resources are greatly saved, and the height of the pesticide spraying assembly can be adjusted through the angle adjusting assembly. The pesticide spraying device has the advantages that the pesticide spraying range and density of the pesticide can be adjusted through the arranged range adjusting assembly, the pesticide can be sprayed at different concentrations for different diseases of the crops, and the pesticide using effect is improved.

The utility model belongs to aerogel foam concrete technical field, specifically disclose a kind of aerogel foam concrete prefabricated part of anti-leakage, including main column and clamping rod, the upper and lower between the left side center of main column is fixed with clamping rod, and the front and back of clamping rod surface are respectively longitudinally fixed with clamping strip one, the upper and lower between the right side center of main column is provided with splicing groove. That aerogel foam concrete prefabricated part of anti-leakage is fixed with clamping rod between the upper and lower between the left side center of main column, several main columns can be assembled together to form wallboard, only need to align the clamping rod of main column left side and the splicing groove of right side, from top to bottom, insert adjacent main column, so that clamping rod is embedded in splicing groove, and the clamping strip one of clamping rod surface is also embedded between the clamping strip two inside splicing groove, again, slurry filling layer one is filled in the concave cavity formed between clamping rod and splicing groove, solve the problem that prefabricated part gap is easy to permeate water.
