Description

Technical Field

[0001] The utility model relates to the technical field of jewelry inspection and testing, in particular to a jewelry inspection and testing workbench. Background Art

[0002] Jewelry inspection and testing is also called jewelry appraisal. Jewelry appraisal is the work of identifying the species, purity, synthesis, artificiality, processing and some origin characteristics of all jewelry, jade and organic gemstones. It can accurately identify the authenticity of jewelry by eliminating counterfeit and imitation jewelry and jade, so as to protect the rights and interests of buyers. Jewelry usually requires a dedicated workbench during the inspection and testing process.

[0003] Chinese Patent Publication No. CN219870985U A workbench for testing and inspecting jewelry When the staff needs to test the jewelry, the staff needs to keep the jewelry stable. At this time, the staff needs to place the jewelry on the first glass plate and activate the limit assembly. Furthermore, the staff needs to slide the support plate downward, so that the second glass plate can follow the support plate and slide downward, and then the second glass cup is pressed against the upper surface of the main board. When the staff releases the support plate, the limit assembly limits the support plate, thereby reducing the probability of the support plate moving upward when subjected to external force. In this process, the staff only needs to slide the support plate downward, which is relatively simple to operate.

[0004] Although the above patent limits the jewelry between the second glass plate and the first glass plate by moving the second glass plate downward, if the jewelry such as bracelets are inspected, the side of the bracelet that contacts the first glass plate cannot be detected. At this time, the staff is required to move the second glass plate to a sufficient distance, turn the bracelet over and then move the second glass plate downward. The operation is rather cumbersome. In addition, the reset spring is compressed and released during the downward movement of the second glass plate, causing the entire workbench to vibrate to a certain extent. Therefore, there is a possibility that the bracelet will fall off the first glass plate due to the vibration. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5In an embodiment of the utility model, a jewelry inspection and testing workbench includes a bottom plate 1, support plates 11 are arranged at both ends of the top surface of the bottom plate 1, a fixing mechanism 2 is arranged between the two support plates 11, a deflation mechanism 3 is fixedly connected to the side of one of the support plates 11, the fixing mechanism 2 includes four circular tubes 21 distributed in a rectangular shape, both ends of the circular tubes 21 are solid structures, an air bag 22 is fixedly connected to the outer wall of the circular tube 21, a plurality of air outlets 211 are opened at equal angles in an annular manner on the outer wall of the circular tube 21 located inside the air bag 22, a connecting pipe 23 is fixedly connected between the two circular tubes 21 at relative positions, and the connecting pipe 23 is communicated with the interiors of the two circular tubes 21 at the corresponding positions, the outer wall of the connecting tube 23 is fixedly connected with a three-way pipe 24 communicated with the interior of the connecting tube 23 at the corresponding position, a conduit is fixedly connected between the two three-way pipes 24, and the outer wall of the conduit is fixedly connected with a three-way pipe 25 communicated with the interior of the conduit, the circular tube 21 and one end close to the connecting tube 23 is rotated through the support plate 11 at the corresponding position, the other end of the circular tube 21 is movably connected through the support plate 11 at the corresponding position, the support plate 11 close to the connecting tube 23 is fixed to the bottom plate 1, and the support plate 11 away from the connecting tube 23 is located on the top surface of the bottom plate 1 and slides.

[0023] Specifically, first, the support plate 11 away from the connecting tube 23 is moved to a position away from the connecting tube 23 so that the support plate 11 is separated from the four circular tubes 21. Then, the bracelet is placed between the four air bags 22 and the support plate 11 is restored to its original position. Since the outer wall of the circular tube 21 is provided with a plurality of air outlets 211 at equal angles in a ring shape, the air bags 22 are connected with the inside of the circular tube 21 at corresponding positions. By inflating the inside of the four circular tubes 21, the four air bags 22 can be inflated until the part where the air bags 22 contact the bracelet is sunken. At this time, the bracelet is fixed between the four air bags 22. At this time, the staff can use a magnifying glass and light to check the texture of the bracelet or detect whether the bracelet has cracks. During surface inspection and testing, the four round tubes 21 can be rotated in one direction at the same time. Since the bracelet is limited between the four air bags 22 and the friction force on the surface of the air bags 22 is relatively large, the four rotating round tubes 21 can drive the bracelet to rotate. Therefore, the staff can inspect and test the condition of the bracelet in all directions. When the inspection and testing of the bracelet is completed, the support plate 11 away from the connecting tube 23 is moved so that the support plate 11 is separated from the four round tubes 21, and then the gas in the four air bags 22 is released through the deflation mechanism 3. At this time, the bracelet can be taken out from between the four air bags 22. The device is simple to operate and there is no need to take the bracelet out from between the four air bags 22 and then fix it, so the inspection and testing efficiency of the bracelet can be improved.

[0024] Embodiment 1

[0025] like Figure 2-4As shown, in the present embodiment, one end of the three-way pipe 25 is fixedly connected with a hose 26, one end of the hose 26 is fixedly connected with an airbag 27, the interior of the hose 26 is communicated with the interior of the airbag 27, an air intake pipe is penetrated and fixed at one end of the airbag 27, the interior of the air intake pipe and the interior of the hose 26 are both provided with a one-way valve, the outer wall of the circular tube 21 and one end close to the connecting pipe 23 are fixedly connected with a double-groove pulley 28, two adjacent double-groove pulleys 28 are connected by belt transmission, the top surface of the bottom plate 1 and one end away from the connecting pipe 23 are penetrated with two symmetrical sliding holes 12, a sliding rod 13 is fixedly connected between the two short side surfaces of the sliding hole 12, both ends of the bottom surface of the support plate 11 away from the connecting pipe 23 are fixedly connected with sliders that slide through the sliding rod 13 at the corresponding position, and a spring 14 is fixedly connected between the slider and the sliding hole 12 at the corresponding position.

[0026] In this embodiment, the staff can hold the airbag 2 27 with one hand and squeeze it back and forth to inflate the four airbags 22, so that the four airbags 22 can fix the bracelet. Since the two adjacent double-groove pulleys 28 are driven by a belt, one of the round tubes 21 can be rotated to make the four round tubes 21 rotate at the same time, so as to drive the bracelet to rotate, thereby facilitating all-round inspection and testing of the fingers. By moving the support plate 11 away from the connecting tube 23, the two springs 14 at the corresponding positions can be compressed, so as to facilitate placing the bracelet between the four airbags 22 or taking the bracelet out from between the four airbags 22. Under the elastic action of the two springs 14, the support plate 11 can automatically support the four round tubes 21, so that the four round tubes 21 are more stable.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the bracelet to be taken out from between the four air bags 22.
