Abstract
The utility model relates to a funnel for a chemical experiment, and belongs to the technical field of chemical experiment ware and equipment. The funnel for the chemical experiment comprises the funnel and is characterized in that a fixing ring is arranged on the lower portion of the funnel and fastened on the funnel, an elastic clamp is arranged on the fixing ring along the center line direction of the funnel, a clamp loop of a half-arc structure is arranged on the elastic clamp, an elastic cushion is disposed on a clamping portion of the elastic clamp, supports rods are arranged on two sides of the top of the funnel in corresponding mode, beams are fixed on the support rods, and placing grooves are disposed on the middle portions of the beams. By aid of the funnel for the chemical experiment, when the funnel is used, an iron stand can be omitted, and the elastic clamp can be directly fixed on a beaker wall; at the time of drainage, one end of a glass rod contacts with the inner side wall of the funnel, the glass rod is obliquely leaned against the placing groove on the beams, and then the drainage can be conducted. Therefore, a method of the drainage with the glass rod in hand is cancelled, the drainage operation is convenient, and the drainage is safe compared with holding of the glass rod in hand particularly at the time of drainage of low concentration sulfuric acid, nitric acid and the like.
Description
Technical field
The utility model relates to a kind of funnel that is used for chemical experiment, belongs to chemical experiment vessel equipment technical field.
Background technology
At present, when making chemical experiment use funnel, it is close on the beaker inwall, will holds glass bar with hand when pouring liquid into and carry out drainage with the iron stand fixed funnel.Adopt the method; Need select to adjust iron stand according to the specification of funnel, beaker, glass bar holds always with hand that the time grown can be very tired, and also very inconvenient during drainage; Especially when the sulfuric acid of drainage low concentration, nitric acid etc., it is very dangerous to hold glass bar with hand.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of funnel that is used for chemical experiment is provided, can saves iron stand, and more convenient when drainage procedure.
The described funnel that is used for chemical experiment of the utility model comprises funnel, and it is characterized in that: the funnel bottom is provided with retainer plate; Retainer plate is fastened on the funnel, is provided with the elasticity folder along hopper centre's line direction retainer plate, and the elasticity folder is provided with the snap ring of half arcuate structure; Be provided with cushion at elasticity folder retaining part; Correspondence is provided with support bar in both sides, funnel top, is fixed with crossbeam on the support bar, and the crossbeam middle part offers standing groove.
Cushion is set prevents to scratch hopper walls and walls of beaker; Support bar is used for the support fixation crossbeam; Crossbeam middle part is offered standing groove and is used to place glass bar, prevents that glass bar from sliding on crossbeam, and the snap ring that half arcuate structure is set can prevent effectively that the utility model from swinging on beaker.In use, directly the elasticity clamping is fixed on the walls of beaker and get final product, saved the trouble of adjustment iron stand; When carrying out drainage, glass bar one end is contacted with the funnel madial wall, and then glass bar is leaned on the standing groove on the crossbeam, thereby can carry out drainage work, cancelled the mode of hand by the glass bar drainage.
Wherein, the cross section of the preferred said standing groove of the utility model is the U-shaped structure, the convenient glass bar of placing.
Compared with prior art, the utlity model has following beneficial effect:
Through the utility model, it is simple in structure, can save iron stand in use, directly the elasticity clamping is fixed on the walls of beaker to get final product; When carrying out drainage; Glass bar one end is contacted with the funnel madial wall, and then glass bar is leaned on the standing groove on the crossbeam, thereby can carry out drainage work; Cancelled the mode of hand by the glass bar drainage; Drainage procedure is convenient, and especially when the sulfuric acid of drainage low concentration, nitric acid etc., drainage is got up than hold glass bar safety with hand.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 analyses and observe the structure for amplifying sketch map for the A-A of Fig. 1;
Among the figure: 1, standing groove 2, crossbeam 3, support bar 4, funnel 5, retainer plate 6, elasticity folder 7, snap ring 8, cushion.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in Figure 1, be used for the funnel of chemical experiment, comprise funnel 4; It is characterized in that: funnel 4 bottoms are provided with retainer plate 5, and retainer plate 5 is fastened on the funnel 4, are provided with elasticity folder 6 along funnel 4 centerline direction retainer plates 5; Elasticity folder 6 is provided with the snap ring 7 of half arcuate structure, presss from both sides 6 retaining parts in elasticity and is provided with cushion 8, and correspondence is provided with support bar 3 in both sides, funnel 4 top; Be fixed with crossbeam 2 on the support bar 3, crossbeam 2 middle parts offer standing groove 1.
In the present embodiment, the cross section of said standing groove 1 is the U-shaped structure; Said support bar 3 can be straight-bar, also can be pole, selects for use support bar 3 to be pole in the present embodiment, further facilitates the placement of glass bar.
In use, directly elasticity folder 6 is fixed on the walls of beaker and gets final product; When carrying out drainage, glass bar one end is contacted with funnel 4 madial walls, and then glass bar is leaned on the standing groove on the crossbeam 21, thereby can carry out drainage work.
