Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a rotary lighting type sterile explosion-proof sight glass. Background Art

[0002] In the chemical industry, it is usually necessary to install explosion-proof sight glasses on the outer wall of the equipment. The specific state of the processing liquid inside the equipment can be directly observed through the explosion-proof sight glasses. Due to the influence of the installation environment, the explosion-proof sight glasses are now blurred when observing the internal medium. In addition, the external support shell and the internal mirror body of the explosion-proof sight glasses are integrated. The medium in the mirror body is observed through the through holes opened on the support shell. The internal medium needs to be observed from the through holes at different angles. Therefore, a rotating illuminated sterile explosion-proof sight glass is urgently needed. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problem, and solves the problem that the liquid inside the explosion-proof sight glass cannot be observed from multiple angles, thereby improving the applicability of the explosion-proof sight glass.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sterile explosion-proof sight glass, comprising an upper shell, a support shell and a lower shell, a lens installed inside the support shell, two groups of sliding assemblies symmetrically arranged on both sides of the support shell, the sliding assemblies axially slidingly fitted between the upper shell and the lower shell, a lighting device clamped on the sliding assembly, the sliding assembly comprising a rolling ball, an elastic member, a movable panel and a mounting seat, the rolling ball movably arranged in the mounting seat and extending toward one side of the lower shell, the movable panel being arranged on the mounting seat away from the side of the sphere, the elastic member being clamped between the rolling ball and the movable panel, the lighting device being limited and pressed against one side of the movable panel and connected and locked to the mounting seat by fasteners.

[0005] By adopting the above technical solution, two sets of sliding assemblies are installed on both sides of the lighting device, and the sliding cooperation between the upper shell and the lower shell is achieved through the balls inside the sliding assemblies. An elastic piece is tightly arranged in the mounting seat to realize the contraction of the balls. During installation, the balls squeeze the elastic piece inward to achieve the contraction. When installed to the specified position, the elastic piece releases the contraction pressure so that the balls are matched with the upper shell and the lower shell. The movable panel is used to provide stability for the elastic piece and at the same time form a limit card for the installation of the lighting device to prevent the lighting device from falling after installation. The overall structure solves the problem of not being able to observe the liquid inside the explosion-proof sight glass from multiple angles, thereby improving the applicability of the explosion-proof sight glass.

[0006] The utility model is further configured such that a mounting through hole is provided on the mounting seat, a limiting arc surface is provided toward one side of the lower shell body through which the mounting is provided, and one end of the rolling ball is provided on the limiting arc surface and extends out from one side of the lower shell body.

[0007] By adopting the above technical solution, the ball can be limited and stabilized to prevent it from falling during rolling operation, while at the same time it can slide in coordination with the upper shell and the lower shell.

[0008] The present invention is further configured such that a first sliding groove is provided on a side of the lower shell facing the limiting arc surface, and one end of the rolling ball is provided in the first sliding groove.

[0009] By adopting the above technical solution, the ball is extended out of the limiting arc surface due to the pressing force of the elastic member, and the extended end forms a sliding fit with the first sliding groove, which can stabilize the sliding stroke of the ball.

[0010] The utility model is further configured as follows: a pressing surface and an abutting portion are provided on the movable panel, the pressing surface is pressed against the elastic member, the abutting portion extends and protrudes toward one side of the lighting device, the lighting device includes a lighting panel and a lamp housing, a mounting flange is provided on the lamp housing, a groove adapted to the abutting portion is provided on the mounting flange, a plurality of first mounting holes are provided on the mounting flange, and corresponding second mounting holes are provided on the mounting seat, the fasteners pass through the first mounting holes in sequence and are screwed into the second mounting holes.

[0011] By adopting the above technical solution, the pressing surface is used to achieve a tight fit with the elastic member, which serves as a stable support for one side of the elastic member. The abutting portion and the groove form an insert fit, which is used for the limited installation of the lighting panel. The elastic member is forced to shrink and make way by squeezing the abutting portion. When the lighting panel is installed, the abutting portion is reset and clamped by the force of the elastic member.

[0012] The utility model is further configured as follows: a plug-in opening is provided on the lamp housing, a positioning groove is provided on the abutting portion, a plug-in board and a lighting lamp are provided on the lighting panel, the lighting lamp array is provided on the plug-in board and faces one side of the supporting shell, and both ends of the plug-in board are plugged into the plug-in opening and clamped in the positioning groove.

[0013] By adopting the above technical solution, the plug-in board is inserted into the positioning groove, which prevents the lighting lamp from shaking after installation and has a good positioning effect.

[0014] The present invention is further configured such that the outer diameter of the abutting portion is smaller than the outer diameter of the pressing surface.

[0015] By adopting the above technical solution, structural interference between the abutting portion and the lamp housing is avoided, thereby achieving the function of retractable limiting.

[0016] The present invention is further configured as follows: a second sliding groove is provided on the upper shell body in a symmetrical manner with the first sliding groove, and the first sliding groove and the second sliding groove are arranged in an arc shape.

[0017] By adopting the above technical solution, the sliding stability of both sides of the sliding component is improved, and the sliding stroke of the lighting device is stabilized. BRIEF DESCRIPTION OF THE DRAWINGS
