Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a melting point tester convenient to protect magnifying glass, include tester body 1 and install magnifying glass 2 in tester body 1 upper surface.
Referring to fig. 1 and 2, the bottom of magnifying glass 2 is connected with connecting rod 3 through the bearing rotation, and the standing groove 4 that is used for holding magnifying glass 2 is offered to the upper surface of tester body 1, and the cross section of standing groove 4 is the T shape, and the one end that magnifying glass 2 was kept away from to connecting rod 3 is rotated through the round pin axle and is connected in the one end of standing groove 4. The notch department slidable mounting of standing groove 4 has and is used for carrying out confined push away lid 5 to standing groove 4, and a spout 41 has all been seted up along the horizontal direction in the both sides of standing groove 4 inner wall, pushes away the both sides limit of lid 5 and slides respectively to inlay and locate in two spouts 41.
When not using the tester, rotate connecting rod 3 and make magnifying glass 2 rotate to standing groove 4 in, then promote to push away and cover 5 and seal standing groove 4, standing groove 4 can protect magnifying glass 2, prevents that magnifying glass 2 is impaired when not using, pushes away and covers 5 and can prevent that the dust from falling into standing groove 4 in, avoids the lens of magnifying glass 2 to receive the pollution.
Referring to fig. 3, a protective pad 6 made of sponge material is further embedded in the placing groove 4, and a positioning groove 61 matched with the magnifier 2 is formed in the protective pad 6. Protection pad 6 can protect magnifying glass 2, receives the striking and damages when preventing that magnifying glass 2 from rotating in the standing groove 4, and constant head tank 61 is used for fixing a position magnifying glass 2, prevents that magnifying glass 2 from taking place relative rotation and striking to pushing away lid 5 with connecting rod 3.
Referring to fig. 2 and 3, two cylindrical elastic columns 51 are horizontally welded on two sides of one end, away from the connecting rod 3, of the push cover 5, a fixing hole 44 matched with the elastic column 51 is formed in the side wall of one end, away from the connecting rod 3, of the placing groove 4, and the elastic column 51 is made of rubber, and the diameter of the cross section of the elastic column 51 is slightly larger than that of the fixing hole 44. When closing standing groove 4 through pushing away lid 5, promote to push away lid 5 and make elastic column 51 inlay establish to fixed orifices 44 in, elastic column 51 closely cooperates and fixes pushing away lid 5 with fixed orifices 44, prevents that the tester from pushing away lid 5 when not using and sliding open and lead to the dust to fall into standing groove 4.
The end of the elastic column 51 far away from the push cover 5 is rounded so as to facilitate the elastic column 51 to be embedded into the fixing hole 44 more easily, and avoid the elastic column 51 being obstructed when embedded into the fixing hole 44 to cause the push cover 5 to be difficult to completely cover the placing groove 4.
A shifting piece 52 is vertically welded at one end of the upper surface of the push cover 5 close to the elastic column 51, so that the push cover 5 is pushed when the placing groove 4 is closed, and the use is convenient.
Referring to fig. 2 and 4, a fixing strip 31 made of rubber is bonded to the side walls of the two sides of one end, away from the magnifier 2, of the connecting rod 3 along the radial direction of the connecting rod 3, and fixing grooves 42 matched with the fixing strip 31 are formed in the two sides of the inner wall of the placing groove 4. When connecting rod 3 rotated to vertical state, two fixed strips 31 just inlayed and locate two fixed slots 42 in, and then fixed connecting rod 3, prevented that connecting rod 3 from taking place to rotate in the use.
The welding has an iron plate 32 on the lateral wall of connecting rod 3 near fixed strip 31 one end, and it has a magnetic sheet 43 to bond on the lateral wall of standing groove 4 near fixed slot 42 one end, and when connecting rod 3 rotated to vertical state, iron plate 32 just with magnetic sheet 43 looks butt. The magnetic force of magnetic sheet 43 adsorbs iron block 32, makes iron block 32 firmly butt in magnetic sheet 43, further fixes connecting rod 3, prevents that connecting rod 3 from rotating and magnifying glass 2's use from causing the influence in the use. Simultaneously, the iron block 32 can limit the rotating angle of the connecting rod 3, so that the connecting rod 3 is just in a vertical state when rotating to the maximum angle, and the sample can be observed through the magnifier 2.
Referring to fig. 4, two side edges of the magnifier 2 are respectively connected with a holding lug 21, the holding lugs 21 and the frame of the magnifier 2 are integrated, and the magnifier 2 is held by hand when the magnifier 2 is used for observing a sample, so that the magnifier 2 is kept fixed, and the sample is observed conveniently.
The implementation principle of the embodiment is as follows: hold and protect magnifying glass 2 when not using the tester through setting up standing groove 4, prevent that magnifying glass 2 is impaired, push away lid 5 and can prevent that the dust from falling into standing groove 4 in, the lens of surface magnifying glass 2 receives the pollution. Through setting up fixed strip 31 and fixed slot 42 so that fix connecting rod 3 when observing the sample, connecting rod 3 takes place to rotate and causes the hindrance to the use of magnifying glass 2 when preventing to observe the sample. Further fix connecting rod 3 when using through setting up magnetic sheet 43 and iron plate 32, make connecting rod 3 keep vertical state, be convenient for observe the sample through magnifying glass 2.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
