[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0033] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a waste liquid collection funnel installation structure for a laboratory bench is provided, and the installation structure mainly includes a laboratory bench 100, a pressure diffuser sleeve 200, a screw-pressed inner sleeve 300, a locking nut 400, and a waste liquid funnel 500. The pressure diffuser sleeve 200 and the screw-pressed inner sleeve 300 are fixedly installed on the laboratory bench 100 by using a locking nut 400 from the table surface, and the waste liquid funnel 500 is detachably installed on the top of the pressure inner sleeve 300.

[0034] Specifically, the diffuser sleeve 200 is installed in the mounting hole 101 of the test bench 100, and the coaxially arranged screw-in inner sleeve 300 is installed in the inner hole thereof, and they are gap-connected with each other to facilitate the rapid installation and removal of the diffuser sleeve 200 and the screw-in inner sleeve 300.

[0035] In order to lock and fix the screw-pressed inner sleeve 300 and the locking nut 400 in the mounting hole 101 of the experimental table 100, a plurality of inclined pressure blocks 303 are arranged at intervals on the lower end circumference of the screw-pressed inner sleeve 300, and the plurality of inclined pressure blocks 303 cooperate with the lower end of the expansion sleeve 200. The top of the screw-pressed inner sleeve 300 is threadedly connected to the waste liquid funnel 500, and the waste liquid funnel 500 is connected to the inner hole of the screw-pressed inner sleeve 300 to form a waste liquid discharge channel.

[0036] When the locking nut 400 is used to rotate and lock the upper end of the screw-in inner sleeve 300, the screw-in inner sleeve 300 moves upward while rotating, thereby driving the inclined pressure block 303 at the lower end to be interference-connected with the inner wall of the lower end of the diffuser sleeve 200, so as to press the lower end of the diffuser plate 202 to deform it outward and press it tightly against the mounting hole 101, thereby stably mounting the screw-in inner sleeve 300 and the locking nut 400 on the experimental bench 100.

[0037] In some of the embodiments, Figure 5 , Figure 6 and Figure 7As shown, the diffuser sleeve 200 adopts a T-shaped hollow sleeve structure design, which includes an annular pressing sheet 201 at the upper end and a plurality of diffuser plates 202. The plurality of diffuser plates 202 are arranged in a circular shape at equal intervals at the bottom of the annular pressing sheet 201. An inlet groove 203 extending upward to the annular pressing sheet 201 is formed between two adjacent diffuser plates 202 for inserting a screw-in inner sleeve 300 from above the diffuser sleeve 200.

[0038] In order to improve the fast upward movement and locking of the screw-pressed inner sleeve 300 in the diffuser sleeve 200 and prevent the screw-pressed inner sleeve 300 from synchronously rotating when the locking nut 400 is tightened, a clamping groove 204 is provided at the bottom of the diffuser plate 202 near the position of the introduction groove 203 on the same side. The plate body corner on the inner side of the top of the clamping groove 204 is arranged as an arc surface or an inclined surface, and the arc surface or the inclined surface is arranged in coordination with the top inclined surface of the inclined pressure block 303.

[0039] When in use, the inclined pressure block 303 at the lower end of the screw-pressed inner sleeve 300 is rotated from the lower end of the inlet groove 203 to the corresponding slot 204. One hand presses the diffuser sleeve 200 to keep it still, and the other hand rotates the locking nut 400. The locking nut 400 simultaneously drives the screw-pressed inner sleeve 300 to move upward during rotation, thereby squeezing the diffuser plates 202 around the diffuser sleeve 200 outward through the inclined pressure block 303 and pressing them tightly against the mounting hole 101, thereby firmly fixing the diffuser sleeve 200 on the experimental bench 100. At the same time, the screw-pressed inner sleeve 300 is also tightly installed in the diffuser sleeve 200 through the locking nut 400, thereby ensuring the stability of the installation of the waste liquid funnel 500.

[0040] In some of the embodiments, in order to ensure that the diffuser sleeve 200 can diffuse stably on the test bench 100, the length of the diffuser plate 202 is set to be greater than the thickness of the test bench 100, so that the lower end of the diffuser plate 202 is located below the mounting hole 101, and then the lower end of the diffuser plate 202 can be tightly pressed against the bottom port of the mounting hole 101 when it bends and deforms outward, thereby preventing the locking nut 400 from shaking or falling off in the mounting hole.

[0041] In some of the embodiments, the diffuser plates 202 are arc-shaped plate structures, there are at least three of them, and they are arranged in a circular shape with equal spacing. As a first preferred embodiment, Figure 7 As shown, there are four diffuser plates 202, which are arranged in a circular shape with equal intervals.

[0042] In some of the embodiments, in order to ensure the service life of the diffuser sleeve 200, the diffuser sleeve 200 adopts an integrated structure, and the annular pressure sheet 201 and the plurality of diffuser plates 202 at the bottom thereof are processed as one piece, and are made of elastic stainless steel or elastic aluminum alloy, and have certain wear resistance and corrosion resistance.

[0043] In some of the embodiments, Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, the screw-pressed inner sleeve 300 is mainly composed of an upper screw sleeve 301, a lower screw sleeve 302 and a plurality of oblique pressing blocks 303. The upper screw sleeve 301 and the lower screw sleeve 302 are an integral structure and are made of galvanized steel pipes. The plurality of oblique pressing blocks 303 are fixed to the outer peripheral body at the lower end of the upper screw sleeve 301 by welding.

[0044] The lower end of the upper screw sleeve 301 is coaxially connected to the lower screw sleeve 302, and a plurality of inclined pressure blocks 303 are arranged on the outer peripheral body of the lower end at equal intervals along its circumference; the plurality of inclined pressure blocks 303 are arranged corresponding to the plurality of inlet grooves 203 and the clamping grooves 204 on the diffuser sleeve 200, and the top thereof is arranged as an inclined surface inclined downward.

[0045] The inclined surface at the top of the inclined pressure block 303 is interference-connected with the inclined surface at the lower end of the diffuser sleeve 200, so that when the inclined pressure block 303 is pulled upward, the lower end of the diffuser plate 202 can be obliquely squeezed to expand outward and tightly pressed against the bottom port of the mounting hole 101.

[0046] In addition, in order to facilitate the quick installation of the screw-pressed inner sleeve 300 in the diffuser sleeve 200, the diameter of the lower screw sleeve 302 is smaller than the diameter of the upper screw sleeve 301, and its length is smaller than the length of the upper screw sleeve 301. This is to facilitate the installation of a drainage pipe at the lower end of the lower screw sleeve 302 in advance, and the diameter of the drainage pipe is slightly smaller than the diameter of the upper screw sleeve 301. When installing, the drainage pipe is inserted from the top of the diffuser sleeve 200 together with the screw-pressed inner sleeve 300, which is convenient and quick to install without frequent bending over from the bottom of the experimental table 100.

[0047] In some of the embodiments, Figure 1 , Figure 3 , Figure 4 and 10 As shown, the locking nut 400 mainly serves to lock and fix the diffuser sleeve 200 and the screw-in inner sleeve 300 on the test bench 100. The locking nut 400 can greatly improve the installation and disassembly maintenance efficiency of the diffuser sleeve 200 and the screw-in inner sleeve 300.

[0048] As required, the inner circumference of the locking nut 400 is provided with an internal thread that matches the external thread on the screw-pressed inner sleeve 300. An anti-slip groove is provided at the edge of the outer circumference of the locking nut 400 to facilitate fast tightening of the locking nut 400. At the same time, an annular protrusion 401 is provided at the bottom circumference of the locking nut 400 so that the screw-pressed inner sleeve 300 can be fully locked and pulled when the locking nut 400 is rotated.

[0049] In some of the embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the waste liquid funnel 500 is funnel-shaped and has a certain opening to facilitate the pouring of waste liquid. The lower end of the waste liquid funnel 500 is threadedly sleeved on the upper end of the screw-pressed inner sleeve 300 and is abutted and connected with the locking nut 400.

[0050] In addition, the waste liquid funnel 500 is installed on the screw-pressed inner sleeve 300 by means of a threaded installation method. The waste liquid funnel 500 of different specifications and sizes can be replaced as needed, and an upper cover can be set on the top of the waste liquid funnel 500 for covering.

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the installation method of the funnel installation structure for collecting waste liquid on the laboratory bench is as follows: first, install the diffuser sleeve 200 in the installation hole 101 of the laboratory bench 100, and make the bottom end of the diffuser sleeve 200 be located below the installation hole 101; secondly, install the locking nut 400 and the drain hose on the upper and lower ends of the screw-pressed inner sleeve 300 respectively, and insert the assembled screw-pressed inner sleeve 300 as a whole into the diffuser sleeve 200 from the top of the laboratory bench 100, and insert the oblique pressure block 303 into the introduction groove 203 accordingly; then, rotate the screw-pressed inner sleeve 300 to remove the oblique pressure block 303 at its lower end from the guide groove 203. The lower end of the insertion groove 203 is rotated into the card groove 204, one hand presses the diffuser sleeve 200 without moving, and the other hand rotates the locking nut 400 to synchronously drive the screw-pressed inner sleeve 300 to move upward, and the diffuser plates 202 around the diffuser sleeve 200 are squeezed outward through the inclined pressure block 303 and pressed tightly against the mounting hole 101, so that the diffuser sleeve 200 and the screw-pressed inner sleeve 300 are firmly fixed on the experimental table 100; finally, the waste liquid funnel 500 is threadedly installed on the top of the screw-pressed inner sleeve 300, and the lower end of the drain hose is inserted into the waste liquid barrel to complete the quick installation of the funnel mounting structure.
