TECHNICAL FIELD
[0001] The utility model relates to the field of laboratory equipment, especially refers to rubber type mixer beaker holder suitable for laboratory iron stand. BACKGROUND
[0002] Iron stand is composed of iron stable base and one iron stick vertical to the base and fixed on the iron base, used to place and fix experimental devices. According to different categories of fixed objects, iron ring, beaker clamp, burette clamp, condenser clamp, iron clamp and other additional instruments can be configured on the iron stick to move up and down.
[0003] Among them, beaker clamp has many implementation ways, such as three claw beaker clamp, four claw beaker clamp and magic tape type beaker holder.
[0004] Three claw beaker clamp and four claw beaker clamp have complex structure and high cost, which is specifically manifested in that the end claw head is rigid structure, and the length and bending angle cannot be adjusted, so that the beaker size range suitable for single specification beaker clamp is small, and different specifications of beaker clamp need to be set for beaker of different size range.
[0005] Magic tape type beaker holder fixes beaker through the way of binding with bandage, and the bandage adopts non-elastic woven belt, such as nylon woven belt, Poly woven belt, canvas belt and the like. One end of the bandage is connected with the fixed seat, and the fixed seat and the other end of the bandage are respectively provided with mother and daughter magic tapes. When in use, the other end of the bandage is wound around the fixed beaker, then is pulled tight and fixed with the fixed seat through the magic tapes. The beaker holder has the advantages of simple structure, low cost and convenient operation, and can be suitable for beakers of various sizes by adjusting the adhesion position of the magic tapes, and has large application range. However, the beaker holder also has obvious defects: on the one hand, after the mother and daughter magic tapes are adhered, the bandage will shrink a certain amount after being released, and since the elastic extension amount of the non-rubber bandage is very limited, it is difficult to bind the beaker tightly even if the bandage is pulled tight with greater force. On the other hand, the adhesion strength of the magic tapes will decrease after being used for many times, and even fail, so that the service life of the holder is short, and the fixing effect will be obviously poor and unreliable in later period. SUMMARY
[0006] The main purpose of the utility model is to solve the problems of tight binding, short service life and unreliable fixing in later period of the existing magic tape type beaker holder, and to construct a rubber type mixer beaker holder which binds beaker with elastic member.
[0007] The utility model provides a rubber type agitator beaker holder suitable for laboratory iron stand, which comprises a fixing base, a fixing part adapted to the beaker to lean and position on the fixing base, and a binding mechanism for binding the beaker on the fixing part, characterized in that the binding mechanism comprises a rubber strap and a lock hook, the lock hook is fixed on the fixing base, one end of the rubber strap is fixed on the fixing base, a plurality of lock holes are arranged on the rubber strap at uniform intervals, and the lock hook is clamped and fixed with one of the lock holes on the rubber strap when fixing the beaker.
[0008] Further, the lock holes on the rubber strap are selected to have appropriate intervals according to the elastic coefficient of the selected strap material and the required pre-tightening force of the beaker to be fixed.
[0009] Further, the fixing part comprises a first side part and a second side part in a V-shaped structure, the concave surface of the V-shaped structure is a V-shaped contact surface for positioning the beaker, one end of the rubber strap is connected to the outside of the first side part, and the lock hook is arranged on the outside of the second side part.
[0010] Further, the lock hook comprises a root part and an end part, the root part is smoothly connected to the end part, a straight line where the vertical surface on the outside of the second side part is projected on a horizontal plane is a first reference line, an irregular curve where the center line of the end part is projected on the horizontal plane is a second reference line, a straight line where the center line of the root part is projected on the horizontal plane is a third reference line, the included angle between the first reference line and the third reference line is an acute angle, and the second reference line is bent forward compared to the third reference line (the side of the beaker holder fixed with the beaker is regarded as forward).
[0011] The acute angle between the root part and the second side part can effectively prevent the rubber strap from slipping off the lock hook, and the reverse hook of the end part bent forward facilitates the lock holes on the rubber strap to pass through the lock hook.
[0012] Further, the lock holes on the rubber strap are generally circular, but the contact area between the circular lock holes and the lock hook is small, the local position of the rubber strap in contact with the lock hook bears a relatively large pressure, and then the rubber strap is prone to damage in the long-term use.
[0013] In order to solve the problem that the rubber strap with circular lock holes is prone to damage in the long-term use, the lock holes on the rubber strap adopt a vertical strip-shaped structure. The setting of the long strip-shaped lock holes effectively increases the contact area between the rubber strap and the lock hook, and improves the service life of the rubber strap.
[0014] Further, the vertical section of the hook in the direction perpendicular to the second reference line and the third reference line is a strip-shaped structure, and the strip-shaped section structure of the hook corresponds to the strip-shaped structure of the strip-shaped lock hole. The vertical section of the hook can be matched with the vertical section of the strip-shaped lock hole to ensure effective contact and uniform stress.
[0015] The size of the strip-shaped lock hole is particularly important. If the length of the strip-shaped lock hole in the vertical direction accounts for a large proportion of the total length of the rubber band in the vertical direction, the connection strength of the connection part above and below the strip-shaped lock hole is small after the rubber band is tensioned, and the rubber band is easy to break. If the length of the strip-shaped lock hole in the vertical direction accounts for a small proportion of the total length of the rubber band in the vertical direction, the contact area of the rubber band and the hook is still small, and the local position of the rubber band and the hook is subjected to a large pressure, so the rubber band is easy to be damaged in the long-term use process.
[0016] Further, the length of the strip-shaped lock hole in the vertical direction accounts for 0.35-0.55 of the total length of the rubber band in the vertical direction, and the vertical section perpendicular to the center line of the hook projected on the horizontal plane is a strip-shaped structure, and the strip-shaped section structure of the hook matches the strip-shaped structure of the strip-shaped lock hole. This setting ensures the connection strength of the rubber band, reduces the possibility of damage of the rubber band in the use process, and prolongs the service life of the rubber band.
[0017] Further, the strip-shaped lock hole includes upper, middle and lower parts, the upper and lower parts are semicircular with the same diameter, and the middle part is square with the same width as the diameter.
[0018] Further, a soft pad is arranged on the V-shaped contact surface.
[0019] Further, a connecting part is arranged behind the fixed part, and the connecting part and the fixed part form a Y-shaped structure. The rear end of the connecting part is connected with a fixing rod for connecting with an iron stand.
[0020] Further, the fixing rod is connected with the connecting part through threads, and the fixing rod can be fixed on the iron stand through a cross clamp.
[0021] Further, a binding tape is arranged on the connecting part for binding the band.
[0022] Further, the fixing seat is a hollow shell structure, comprising a V-shaped rear shell and a V-shaped front cover, the V-shaped front cover and the V-shaped rear shell are connected through buckling, the lock hook is arranged on one side of the rear shell, and the front side of the front cover is the contact surface.
[0023] Further, the rear side of the front cover is provided with a columnar hook, the inside of the rear shell is provided with a supporting structure for supporting the columnar hook, and one end of the rubber band is connected with the columnar hook through a sleeve structure.
[0024] Further, the V-shaped contact surface is composed of a first side vertical surface, a middle arc surface and a first side straight surface, and a soft protective pad is arranged on each of the first side vertical surface and the second side vertical surface.
[0025] The rubber type beaker holder suitable for the laboratory iron stand disclosed in the application can fasten the rubber band through the lock hook, thereby not only maintaining the advantages of the magic tape type beaker holder, such as simple structure, low cost and wide applicable size range of beakers, but also effectively overcoming the problems of short service life of the magic tape and obvious deterioration of the fixing effect with the increase of the number of uses, and the rubber band has a large elastic extension amount, can effectively adapt to the tension and relaxation in the binding process, and can tightly fix the beaker. In addition, the sharp angle structure between the lock hook and the second side and the reverse hook of the end portion bent forward facilitate the lock hole on the rubber band to pass through the lock hook and effectively avoid the rubber band from slipping off the lock hook, and the lock hole on the rubber band is in a long strip structure, thereby effectively increasing the contact area of the rubber band and the lock hook, ensuring the connection strength of the rubber band, and greatly reducing the possibility of the rubber band being broken in the use process.
