Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present utility model are used to distinguish two entities or parameters with the same name but different, so "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present utility model. This will not be elaborated one by one in the subsequent embodiments.

[0023] The terms of direction and position mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "top", "bottom", "side", etc., are only with reference to the direction or position of the accompanying drawings. Therefore, the terms of direction and position used are for explaining and understanding the present utility model, rather than a limitation on the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, it is an embodiment of the present utility model. A laboratory sink cabinet includes a cabinet body 1 and a sink 2 arranged on the top of the cabinet body 1. A faucet 3 is arranged on the top of the sink 2, a drainage cavity 4 is arranged at the bottom of the sink 2, a convex platform 5 protrudes from the top edge of the sink 2, and a plurality of drip racks 6 are distributed on the side wall of the convex platform 5 close to the drainage cavity 4. Each drip rack 6 is inclined with the side wall of the convex platform 5, and the end far from the side wall of the convex platform 5 extends away from the drainage cavity 4. A drainage arc surface 7 is arranged at the connection between the side wall of the convex platform 5 close to the drainage cavity 4 and the sink 2.

[0025] The beneficial effects of such a setting are as follows. A drip rack is provided on the sink of the sink cabinet of the present utility model for drying the washed utensils. The drip rack is located on the side wall of the top boss of the sink and is inclined to facilitate the utensils to be inverted on the drip rack. The water remaining on the utensils during drying can directly flow along the drainage arc surface into the drainage cavity, keeping the table clean and tidy and reducing the risk of the washed utensils being contaminated.

[0026] Furthermore, a storage position 8 is recessed on the side wall of the boss 5 close to the drainage cavity 4. A plurality of convex ribs 9 protrude from the bottom surface of the storage position 8. A waste liquid bottle 10 is also provided in the storage position 8, and the waste liquid bottle 10 is placed on the convex ribs 9.

[0027] The beneficial effects of such a setting are as follows. The waste liquid bottle is used to collect waste liquid such as hazardous chemical waste generated in biochemical experiments that cannot be directly discharged into the sink. The waste liquid bottle is lifted by the convex ribs, so that there is a certain ventilation space between the bottom of the waste liquid bottle and the bottom surface of the storage position, facilitating the storage position and the waste liquid bottle to remain dry.

[0028] Furthermore, the faucet 3 is installed at the connection between the side wall of the boss 5 close to the drainage cavity 4 and the sink 2. Both sides of the faucet 3 are communicated with a secondary faucet 11, and both of the secondary faucets 11 are rotatably connected to the faucet 3.

[0029] The beneficial effects of such a setting are as follows. The faucet and the secondary faucets can rotate, making it more convenient to clean the corners of the sink and applicable to more cleaning situations.

[0030] Furthermore, a water inlet pipe 12 connected to the faucet 3 and a water outlet pipe 13 connected to the drainage cavity 4 are provided in the cabinet 1. A water pump 14 is connected between the water outlet pipe 13 and the drainage cavity 4. Both the water inlet pipe 12 and the water outlet pipe 13 penetrate through the top of the boss 5 and are both connected with water pipe connectors 15 having the same structure. The water pipe connector 15 is threadedly connected with an end cover 16, and the water outlet pipe 13 is connected to the water pipe connector 15 through the end cover 16.

[0031] The beneficial effects of such a setting are as follows. Both the water inlet pipe and the water outlet pipe penetrate through the top of the boss, realizing the water pipe layout of upper water inlet and upper water outlet. The water outlet pipe is helped to drain quickly by the water pump. The water pipe connector is used to dock with the water source or the drainage mechanism.

[0032] Furthermore, a button 17 penetrates through the side wall of the water pipe connector 15. The button 17 includes a ring buckle 18 located in the inner cavity of the water pipe connector 15. A first spring 19 abuts between the ring buckle 18 and the inner wall of the water pipe connector 15. An inclined conical surface 20 is provided inside the ring buckle 18.

[0033] The beneficial effects of such a setting are as follows. By changing the position of the buckle through the button, it is convenient to unlock the buckle. The first spring helps the buckle to reset. The inclined conical surface facilitates the insertion of the docking head connected to the water pipe joint, realizing quick docking. The docking head is the connection interface of the drainage mechanism.

[0034] Furthermore, a check valve assembly is also provided in the inner cavity of the water pipe joint 15. The check valve assembly includes a connecting column 21 and a slider 22. One end of the connecting column 21 is provided with a clamping block 23 and the other end is provided with a resisting block 24. The resisting block 24 abuts against the water outlet pipe 13 and is penetrated with a plurality of flow holes 25. One side of the slider 22 abuts against the inner wall of the water pipe joint 15 and the other side abuts against the clamping block 23. A second spring 26 is abutted between the slider 22 and the resisting block 24. The slider 22 reciprocally slides in the inner cavity of the water pipe joint 15 through the second spring 26.

[0035] The beneficial effects of such a setting are as follows. The check valve assembly can prevent water leakage when the water pipe joint is separated from the docking head, which is particularly important for upward water discharge. Through the cooperation of the slider and the connecting column, and with a second spring abutted therebetween, the self-locking function is realized. When the docking head is inserted into the water pipe joint, the edge of the docking head abuts against and presses down the slider, causing the slider and the clamping block to be misaligned, and the water flows through the flow holes. When the docking head is pulled out, the slider resets under the action of the second spring, and the slider and the clamping block are clamped to stop the water flow.

[0036] Furthermore, a sliding sleeve 27 extends from one end of the slider 22 close to the resisting block 24, and a sleeve 28 extends from one end of the resisting block 24 close to the slider 22. The sliding sleeve 27 and the sleeve 28 are inserted and connected, and a sealing ring 29 is further provided between the sliding sleeve 27 and the sleeve 28.

[0037] The beneficial effects of such a setting are as follows. The sliding sleeve and the sleeve are inserted and matched to separate the cavity for installing the second spring from the flow channel, preventing the liquid from contacting and affecting the second spring to make it ineffective, and further improving the sealing performance through the sealing ring.

[0038] Furthermore, side doors 30 are hinged on both side surfaces of the cabinet body 1.

[0039] The beneficial effects of such a setting are as follows. It is convenient to repair the internal parts of the cabinet body through the side doors that can be opened on both sides.

[0040] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
