6results about How to "Guaranteed assembly strength" patented technology

The assembled anchor rod is used to solve the technical problem mentioned in the background technology that some of the current assembled anchor rods often break at the anchor rod joints during the process of being driven into the rock formation. The assembled anchor rod comprises a coaxial driving rod and an additional rod, wherein one end of the driving rod is provided with a threaded hole coaxial with the driving rod, the additional rod is a screw rod and one end of which is threadedly connected in the threaded hole, a connecting ring is fixedly sleeved on the additional rod for synchronous movement with the screwing of the additional rod and abutment with the end of the driving rod, a collar is slidably sleeved on the periphery of the driving rod for sliding sleeves on the circumferential periphery of the abutment between the driving rod and the connecting ring as the driving rod is driven. The assembly of the assembled anchor rod is simple, and the structural strength of the assembled joints of the anchor rods can be enhanced during the process of being driven into the rock formation. The assembled anchor rod is mainly used for anchoring in the surrounding rock to support the tunnel.

This invention provides an air conditioner, relating to the technical field of air conditioning devices. The air conditioner includes an injection-molded panel, which comprises a panel body and an assembly structure. The panel body includes a main thinning area and a mating reinforcement area. The assembly structure is disposed in the mating reinforcement area and is used to install components to be assembled onto the injection-molded panel. In this air conditioner, the panel body is divided into a main thinning area and a mating reinforcement area; that is, the main body of the panel body is a thinning structure, while the mating portion with the assembly structure is a reinforcement structure. The main thinning area uses less material due to the reduced wall thickness, thereby lowering production costs; the mating reinforcement area ensures assembly strength through structural reinforcement. Therefore, if the rear panel and other panels of the air conditioner adopt the structure of the injection-molded panel provided by this invention, not only can assembly strength be guaranteed, but production costs can also be significantly reduced.

The present invention relates to an exhaust gas recirculation cooler using a split air outlet main plate, the cooler includes an air inlet chamber, an air inlet main plate, an air inlet sealing pad, a heat dissipation pipe group, a shell, an air outlet main plate, an air outlet sealing pad and an air outlet chamber, the air outlet main plate includes an insert and a diaphragm, an insert mounting hole is provided in the middle of the diaphragm, the insert mounting hole is vertically provided with a flange structure on the side away from the heat dissipation pipe group installation, and the insert is fixedly arranged on the flange structure of the insert mounting hole. The air outlet main plate assembly adopts a combined structure, the thicker insert can ensure the laser welding strength, and the thinner diaphragm can play a role similar to a "spring", which can effectively compensate for the deformation caused by the thermal expansion of the heat dissipation pipe, release thermal stress, and greatly reduce the risk of fatigue fracture. The design of this structure is suitable for heat dissipation pipes of different lengths, and the longer the heat dissipation pipe, the more obvious the effect of reducing thermal shock failure. The test results show that the use of the air outlet main plate of the present invention can reduce 20% to 30% of the thermal shock stress, and the heat shock resistance life of the cooler is increased by about 43%.

The modular handheld dust collector convenient to disassemble and assemble comprises a dust collector handle, an air inlet pipe is embedded in a first mounting groove in the dust collector handle, and the front end of the air inlet pipe is in butt joint with a dust collection pipe connector in a sealed mode; the connecting assembly is in butt joint with a third connecting base provided with a dust collecting pipe in a penetrating mode, the connecting assembly comprises a first connecting base axially inserted and positioned in the dust collecting pipe connector and a second connecting base located outside the dust collecting pipe connector in a sleeving mode, an inner cavity in one side of the third connecting base axially extends out of an insertion pipe, and the insertion pipe is inserted into the first connecting base; the outer edge of one side of the third connecting seat sleeves the dust collecting pipe joint and is spliced with the outer end surface of the second connecting seat; and the dust collector host is butted with the dust cup and is hermetically assembled at the top of the dust collector handle together with the dust cup. The problems that a locking structure is easily touched by mistake at an air inlet of an existing dust collector, so that the structure is unlocked and loosened, an air duct system in the dust collector locally leaks air, and the dust collection and cleaning efficiency is influenced can be solved.

The present invention provides an assembled combined formwork system and a construction method thereof, comprising a wall column formwork unit and a floor formwork unit; the wall column formwork unit comprises: four groups of wall column formwork groups, each group comprises two wall column formworks, the wall column formwork comprises a plurality of first vertical formworks and a second vertical formwork, the first vertical formworks and the adjacent second vertical formworks are spliced; two positive angle connection formworks are fitted to form a positive angle corner; two wall column formworks are connected through a negative angle corner formwork to form a negative angle corner; the lower end surface of the wall column formwork is connected with a bottom angle aluminum; the negative angle connection formwork is connected with the floor formwork; a plurality of tension screws are inserted into the fixing holes, the outer surface of the wall column formwork is provided with a back rib, and a nut forms a fastening between the tension screws and the back rib; a plurality of connecting K plates are respectively connected to the upper end surface and the lower end surface of the wall column formwork. The system saves the number of pins used, reduces the assembly cost, and the wall column formwork cooperates with the use of tension screws, nuts and back ribs to ensure the rigidity and strength of the wall column formwork.

A shutter structure of a charging pile comprises a protective frame and Z-shaped shutter blades located in the protective frame, each Z-shaped shutter blade comprises a Z-shaped shutter blade body, each Z-shaped shutter blade body is in a Z shape formed by a first blade, a second blade and a third blade, ear plate folded edges are arranged on the two sides of each second blade, the ear plate folded edges are perpendicular to the second blades, and the first blade and the second blade are arranged on the protective frame. The folded edge of the lug plate on each side is fixed on the protective frame on the corresponding side through a rivet; a bent edge is arranged at the end of the third blade in each Z-shaped louver blade body, an included angle is formed between the bent edge and the third blade, a through hole is formed in the bent edge, and the first blade in the other Z-shaped louver blade is inserted into the through hole, so that every two adjacent Z-shaped louver blades coincide with each other. According to the utility model, the internal buckle structure prevents impurities, dust and water in the outside from directly entering the interior of the charging pile; and meanwhile, light cannot directly irradiate the interior of the charging pile, so that the sunlight is prevented from directly irradiating electronic components and a charging module in the charging pile.
