Description

Technical Field

[0001] The utility model belongs to the technical field related to liquid transfer guns, and particularly relates to a liquid transfer gun support seat. Background Art

[0002] A pipette is a type of pipette, commonly used in laboratories to transfer small or trace amounts of liquid. Different specifications of pipettes are equipped with different sizes of pipette tips, and the shapes produced by different manufacturers are slightly different. The pipette is a precision instrument, and it must be used and stored with caution to prevent damage and avoid affecting its range. In the laboratory, in order to facilitate the inspection of liquid medicine, it is necessary to use pipettes of various specifications. Therefore, in order to ensure the stable storage of pipettes in the laboratory, it is necessary to use a corresponding support seat;

[0003] However, the existing pipette support base does not have the function of limiting the position of the mounted pipette during use. Therefore, after the pipette is mounted on the support base, the rod position of the pipette will still shake, which will lead to insufficient stability of the pipette mounting. At the same time, since the support base does not have the function of adjusting the angle, after the pipette is mounted, the three-dimensional space occupied by the support base will be increased, so it is easy to be accidentally touched by outsiders, which will cause the support base to easily tip over and damage the mounted pipette. To this end, we provide a pipette support base to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a pipette support seat, which can limit the position of the pipette after the positioning U block is installed on the end surface position of the angle plate to avoid the pipette from being offset after being hung. At the same time, the angle adjustment between the angle plate and the U-shaped base frame can reduce the space occupied by the support seat to avoid accidental contact.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a pipette support seat, comprising a U-shaped base frame and an angle plate located at the inner side of the U-shaped base frame; the upper end surface of the angle plate is provided with a plurality of positioning U blocks which are locally arranged linearly from the front to the rear; a pressing hole is provided at the end position of the U-shaped base frame connected to the angle plate; tooth openings are provided at the inner side positions adjacent to the two pressing holes; a pressing rod is provided inside the pressing hole; a rack meshing with the tooth opening is fixed at the middle position of the circumference of the pressing rod; through holes which are consistent with the front and rear directions of the pressing holes are provided at the front and rear end surfaces of the angle plate; the end of the pressing rod which passes through the pressing hole is slidably arranged at the inner position of the through hole.

[0007] The utility model is further configured that the inner end surface of the through hole is provided with a movable hole whose aperture is larger than that of the through hole, and the end surface of the through hole of the pressing rod is fixed with a movable circular plate which is slidably connected with the inner wall of the movable hole.

[0008] The utility model is further configured that the inner side wall of the movable hole is provided with a plurality of positioning strips evenly distributed in a ring shape.

[0009] The utility model is further configured that notches are provided at positions of the circumferential sides of the movable circular plate corresponding to the positioning strips, and the positioning strips pass through the inner positions of the notches corresponding to the corresponding positions.

[0010] The utility model is further configured that a spring is fixed to the end surface of the movable circular plate opposite to the pressing rod, and the other end of the spring is in contact with the inner end surface of the movable hole.

[0011] The utility model is further configured that a counterweight bar is fixed to the inner side wall of the U-shaped base frame, and the counterweight bar and the pressing rod are arranged in a vertical state.

[0012] The utility model is further configured that a metal strip is fixed to the upper end surface of the angle plate, and the metal strip is located at an end position away from the through hole.

[0013] The utility model is further configured that the end faces of the positioning U blocks relative to the angle plate are connected to the metal strips, and the end faces of the positioning U blocks are fixed with magnetic plates adsorbed to the metal strips.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, the hook at the end of the pipette is hung at the end position of the angle plate, and the rod of the pipette is placed in the internal position of the positioning U block. When the positioning U block is limited at the end surface position of the angle plate, the positioning U block will limit the position of the pipette, so that the end surface position of the pipette at the angle plate will not be arbitrarily offset, thereby ensuring the stability of the pipette after hanging.

[0016] 2. When the utility model is in use, the pressing rod is pressed in the internal position of the pressing hole, so that the pressing rod drives the rack to move out of the position of the tooth mouth, so that the pressing rod no longer has the function of limiting the angle of the angle plate and the U-shaped base frame, thereby the angle plate can be rotated, and then after the pressing rod is released, the pressing rod will be reset, so that the rack on the side of the pressing rod will re-engage the inside of the tooth mouth, so that the angle between the angle plate and the U-shaped base frame will be limited again. Therefore, after the pipette gun is hung on the angle plate, the angle between the angle plate and the U-shaped base frame can be controlled, and the space occupied by the angle plate can be reduced to avoid accidental contact.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-6The utility model is a pipette support seat. After the positioning U block 3 is installed on the end surface position of the angle plate 2, the pipette can be limited to avoid the pipette from being offset after being hung. At the same time, the angle adjustment between the angle plate 2 and the U-shaped base frame 1 can reduce the space occupied by the support seat to avoid accidental contact.

[0030] Specifically, a U-shaped base frame 1 and an angle plate 2 located at the inner side of the U-shaped base frame 1; the upper end surface of the angle plate 2 is provided with a plurality of positioning U-blocks 3 which are locally arranged linearly from front to back, a pressing hole 103 is provided at the end position of the U-shaped base frame 1 connected to the angle plate 2, and tooth openings 102 are provided at the inner sides adjacent to the two pressing holes 103, a pressing rod 4 is provided inside the pressing hole 103, and a rack 401 meshing with the tooth opening 102 is fixed at the middle position of the peripheral side of the pressing rod 4, and a through hole 204 which is consistent with the front and rear directions of the pressing hole 103 is provided on the front and rear end surfaces of the angle plate 2, and the end of the pressing rod 4 passing through the pressing hole 103 is slidably set in the inner position of the through hole 204.

[0031] The operation process of this embodiment is as follows: through the use of the above-mentioned structure, when the pipette gun needs to be placed on the support seat, the hook at the end of the pipette gun can be hung on the end position of the angle plate 2, and then the rod of the pipette gun can be placed in the internal position of the positioning U block 3, and then when the positioning U block 3 is limited to the end surface position of the angle plate 2, the positioning U block 3 will limit the pipette gun, so that the end surface position of the pipette gun on the angle plate 2 will not be arbitrarily offset, thereby ensuring the stability of the pipette gun after hanging, and at the same time when the angle plate needs to be adjusted 2 and the U-shaped base frame 1, the pressing rod 4 can be pressed in the internal position of the pressing hole 103, so that the pressing rod 4 drives the rack 401 to move out of the position of the tooth mouth 102, so that the pressing rod 4 no longer has the effect of limiting the angle of the angle plate 2 and the U-shaped base frame 1, thereby the angle plate 2 can be rotated, and then after releasing the pressing rod 4, the pressing rod 4 will be reset, so that the rack 401 on the side of the pressing rod 4 will re-engage with the inside of the tooth mouth 102, so that the angle between the angle plate 2 and the U-shaped base frame 1 is limited again. Specific embodiment 2

[0033] See also Figure 2 , 3 , 4, 6, based on the specific embodiment one, the movable circular plate 402 and the pressing rod 4 can be automatically reset through the compression and pushing of the spring 404, and at the same time, the positioning strip 203 is located inside the recess 403 to ensure the stability of the pressing rod 4 in limiting the angle plate 2 and the U-shaped base frame 1.

[0034] Specifically, the inner end surface of the through hole 204 is provided with a movable hole 202 whose aperture is larger than that of the through hole 204, and the end surface of the through hole 204 of the pressing rod 4 is fixed with a movable circular plate 402 which is slidably connected with the inner wall of the movable hole 202, and the inner side wall of the movable hole 202 is provided with a plurality of positioning strips 203 evenly distributed in a ring shape, and the circumferential side of the movable circular plate 402 is provided with recesses 403 at the positions corresponding to the positioning strips 203, and the positioning strips 203 pass through the corresponding internal positions of the recesses 403 at the corresponding positions, and the end surface of the movable circular plate 402 opposite to the pressing rod 4 is fixed with a spring 404, and the other end of the spring 404 is in contact with the inner end surface of the movable hole 202.

[0035] The operation process of this embodiment is as follows: when the pressing rod 4 is pressed inside the pressing hole 103, the pressing rod 4 can drive the moving circular plate 402 to compress the spring 404. Therefore, after releasing the pressing rod 4, the spring 404 will push the moving circular plate 402 to reset, and the pressing rod 4 will move back to the original position of the pressing hole 103. At the same time, since the positioning bar 203 is located inside the recess 403 on the side of the moving circular plate 402, the positioning bar 203 will limit the moving circular plate 402, so that the moving circular plate 402 will not rotate inside the moving hole 202, thereby ensuring the stability of the pressing rod 4 in limiting the angle plate 2 and the U-shaped base frame 1. Specific embodiment three

[0037] See also Figure 2-5 On the basis of the first specific embodiment, the position of the positioning U block 3 on the upper end surface of the angle plate 2 can be adjusted by adsorption or separation between the magnetic plate 301 and the metal strip plate 201 .

[0038] Specifically, a counterweight bar 101 is fixed to the inner wall of the U-shaped base frame 1, and the counterweight bar 101 is arranged in a vertical state with the pressing rod 4. A metal strip plate 201 is fixed to the upper end face of the angle plate 2, and the metal strip plate 201 is at an end position away from the through hole 204. The end faces of the positioning U-block 3 relative to the angle plate 2 are connected to the metal strip plate 201, and the end faces of the positioning U-block 3 are fixed with magnetic plates 301 that are adsorbed with the metal strip plate 201.

[0039] The operation process of this embodiment is as follows: by using the counterweight bar 101, the staff can prevent the U-shaped base frame 1 from deviating at will when adjusting the angle of the angle plate 2. At the same time, the magnetic plate 301 is disconnected from the metal strip plate 201, and the positioning U block 3 is disconnected from the angle plate 2, so as to adjust the position of the positioning U block 3. After the magnetic plate 301 is disconnected from the metal strip plate 201, the positioning U block 3 can be connected to the angle plate 2, and the positioning U block 3 cannot deviate.
