This utility model discloses a device for checking the interlocking relationship between a rail transit signal and a turnout, comprising a housing, an electrical control assembly, and a mounting mechanism. The housing has a receiving cavity and is formed by combining a front shell and a rear shell. The electrical control assembly is installed within the receiving cavity. The mounting mechanism has a locked state and an unlocked state, and includes a first mounting base and a second mounting base. The first mounting base is used to install on the signal, and the second mounting base is connected to the rear shell. The first mounting base has a first adjusting head, and the second mounting base has a second adjusting head. When the mounting mechanism is in the locked state, the first adjusting head and the second adjusting head are engaged to fix the second mounting base to the first mounting base. When the mounting mechanism is in the unlocked state, the second adjusting head can move relative to the first mounting base, allowing the second mounting base to disengage from the first mounting base. This achieves the effect of quick replacement and disassembly, facilitating subsequent maintenance.

The utility model discloses a multistage filtering device which comprises a shell, the shell is cylindrical, the bottom of the shell is open, a bottom cover is attached to the bottom of the shell, a liquid inlet pipe is fixedly connected to the bottom end of the side wall of the shell, a liquid outlet pipe is fixed to the middle of the top wall of the shell, and a plurality of filtering net cylinders are arranged in the shell. The multiple filter screen cylinders are different in diameter, meshes of the multiple filter screen cylinders are sequentially enlarged from inside to outside, connecting assemblies are fixed to the two sides of the upper surface of the bottom cover, and two connecting plates connected with the connecting assemblies in a matched and clamped mode are fixed to the bottom end of the outer side wall of the shell. According to the utility model, the shell, the bottom cover, the liquid inlet pipe, the liquid outlet pipe and the plurality of filter screen cylinders are arranged, the plurality of filter screen cylinders which are mutually sleeved are utilized to realize graded filtration of mother liquor, the filter screen cylinders are prevented from being quickly blocked, and the mother liquor can be more thoroughly filtered and the filtering effect is better by adopting a graded filtration mode.

This utility model discloses a connection structure for a tray plate, comprising: a tray plate body, with two insertion slots at one end of the tray plate body; two fixing seats fixedly welded to the bottom wall of the end of the tray plate body with the two insertion slots; a first through slot on the front fixing seat; and a threaded groove on the front side wall of the rear fixing seat; a locking rod movably inserted into the first through slot; and two insertion seats fixedly welded to the bottom wall of the end of the tray plate body away from the insertion slots, the insertion seats being adapted to the insertion slots; and a second through slot on each of the two insertion seats. In use, this utility model enables quick and easy connection between two tray plate bodies when they are joined, while also facilitating disassembly, greatly improving the efficiency of assembly and disassembly. It also has the advantages of simple overall structure, low production difficulty, and low cost, making it worthy of promotion.

The utility model discloses a copper bolt strength detection device, which comprises a tensile machine and a cross beam, the cross beam is fixedly connected with the driving end of the tensile machine, a base is fixed on the upper surface of the tensile machine, a plurality of groups of mounting components and supporting components are matched with the base, a T-shaped groove is formed in the top of the base, and the mounting components and the supporting components are arranged in the T-shaped groove. Each installation assembly comprises a first clamping block, the supporting assembly comprises a second clamping block, and the section of the first clamping block and the section of the second clamping block are both in a T shape. According to the utility model, the tensile machine, the cross beam, the base, the clamping assembly and the mounting assembly are arranged, and the mounting assembly and the base can be quickly and fixedly connected in a clamping manner, so that the mounting assembly can be quickly detached from the base, and the clamping assembly can clamp bolts with different diameters for detection; and the installation assemblies with different sizes of thread grooves can be replaced to adapt to detection of bolts with different sizes, so that the universality and the convenience of the detection device are improved.
