Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory supplies and relates to a drip rack for a laboratory. Background Art

[0002] A drip rack is a common tool in laboratories, used to drain water from test tubes. It is acid-resistant, alkali-resistant, and corrosion-resistant. Existing drip racks consist of a drip plate and a drip rod attached to the plate. Depending on the layout of the drip plate, drip racks can be categorized as single-sided or double-sided. Depending on the material of the drip plate, they can be divided into PP drip racks, physical and chemical plate drip racks, and stainless steel drip racks.

[0003] A search revealed a Chinese patent application document, CN202020702718.6, and CN212370252U, which discloses a drip stand for analytical laboratories. This drip stand comprises a vertical plate and a chassis. The vertical plate has multiple hanging rods on its front side, and multiple mounting brackets with internally threaded holes on the front side. The internally threaded holes in the mounting brackets are arranged at an angle. The hanging rods have external threads at their bottoms and are threaded into the mounting brackets. The chassis is a box-shaped body with multiple drainage holes on its upper side. A water collection tank is integrally formed on the inner side of the upper side. The bottom of the water collection tank has drainage holes on one side of the chassis. The drainage hole side of the bottom plate of the water collection tank is inclined downward. A counterweight plate is integrally formed on the lower side of the chassis. While the hanging rods of this drip stand are easily removable, the water collection tank drains smoothly, and the counterweight plate effectively prevents the drip stand from tipping over when fully loaded with vessels, this type of drip stand has a limited height. The device is too high to access test tubes from high locations, and the number of test tubes that can be stored is relatively small.

[0004] Based on this, we designed a drip rack for laboratory use. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a laboratory drip rack. The technical problem to be solved by the device is: how to increase the height of the drip rack, increase the number of test tubes stored, and make it convenient for operators to take and place test tubes.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A drip rack for laboratory use comprises an inclined plate, a support frame is provided on the back of the inclined plate, a plurality of equally spaced vertical slide grooves and two horizontal slide grooves are provided on the front of the inclined plate, a plurality of lifting plates are provided on the front of the inclined plate for sliding up and down, a vertical slider is provided on the back of the lifting plate, and the vertical slider is damped and slidably arranged in the vertical slide grooves at corresponding positions, a plurality of transverse plates are provided on the front of the inclined plate for transverse sliding, two transverse sliders are provided on the back of the transverse plate, and the two transverse sliders are respectively slidably arranged in the transverse slide grooves at corresponding positions, and a plurality of equally spaced diagonal support rods are provided on the front of both the lifting plate and the transverse plate.

[0008] The support frame includes an integrally formed curved support plate, the upper end of which is fixed to the back of the inclined plate, and a thinning groove is provided at the bend of the curved support plate. A water receiving trough is placed on the curved support plate, and the water receiving trough is located directly below the inclined plate.

[0009] With the above structure, when in use, the water trough can catch the water droplets sliding along the inclined plate. The curved support plate can not only support the inclined plate, but also provide jitter buffering for the inclined plate at the bend. When the inclined plate is accidentally hit, it can shake slightly, reducing the risk of tipping over and improving the protection effect of the test tube.

[0010] A first sharp corner is provided below the lifting plate, and a second sharp corner is provided on the upper end of the transverse moving plate.

[0011] With the above structure, when the lifting plate is pulled down, the probability of the first sharp corner and the second sharp corner directly contacting each other is small. The descending lifting plate can directly squeeze the transverse plate to both sides, and the operator does not need to manually move the transverse plate, which makes the operation more convenient.

[0012] Two symmetrically distributed first magnetic blocks are fixed on both sides of the inclined plate, and a second magnetic block is embedded on the outer side of the transverse plate at the edge. The first magnetic block and the second magnetic block at the corresponding position have the same poles facing each other.

[0013] With the above structure, when in use, the repulsive force between the first magnetic block and the second magnetic block will push the edge of the transverse plate to the middle by a certain distance, thereby making the first sharp corner and the second sharp corner more likely to diverge from each other, thereby improving the smoothness of operation and the operator's experience.

[0014] A plurality of weight-reducing grooves are provided above the inclined plate.

[0015] With the above structure, the weight-reducing grooves can reduce the weight above the inclined plate, thereby lowering the center of gravity of the inclined plate and further improving its stability.

[0016] The diagonal support rod includes a support rod, a soft sleeve is provided on the upper end of the support rod, and an arc-shaped clamping plate is fixed below the support rod. The lifting plate and the transverse plate are both provided with a plurality of arc-shaped grooves matching the arc-shaped clamping plate, and the arc-shaped clamping plate is clamped in the arc-shaped grooves.

[0017] With the above structure, the support rod tilts the arc-shaped clamping plate upward and firmly clamps it in the arc-shaped groove under the action of its own gravity and the gravity of the test tube. Moreover, the arc-shaped clamping plate can be detached from the arc-shaped groove by rotating the support rod upward, which makes it convenient for operators to replace support rods of different lengths and expands the scope of application of the device.

[0018] Compared with the existing technology, this laboratory drip rack has the following advantages:

[0019] By tilting the plate, lifting plate, transverse plate and diagonal support rod, the lifting plate can be moved downward and the transverse plate can be squeezed to both sides, allowing operators to more conveniently take and place test tubes at higher places, thereby increasing the height limit of the drip rack and being able to store more test tubes without expanding the floor area.

[0020] Through the support frame, the curved part of the curved support plate can rely on its own elastic force to support the inclined plate while providing a certain buffering effect on the shaking of the inclined plate, reducing the risk of the inclined plate tipping over when it is slightly impacted, and improving the protection effect on the test tube.

[0021] Through the first sharp corner, the second sharp corner, the first magnetic block and the second magnetic block, the risk of the lifting plate colliding with the transverse plate when descending can be reduced, so that the first sharp corner and the second sharp corner are more likely to diverge from each other, and the operator does not need to manually move the transverse plate, thereby improving the operation smoothness and the operator's user experience.

[0022] The test tube is supported by the diagonal support rod, and the soft cover can prevent the bottom of the test tube from being damaged by collision. Moreover, the arc-shaped clamping plate can be detached from the arc-shaped groove by rotating the support rod upward, which makes it convenient for the operator to replace support rods of different lengths and expands the scope of application of the device.

When the inclined plate 1 is accidentally hit, it can shake slightly to reduce the risk of tipping over and improve the protection effect on the test tube.

[0036] A first sharp corner 10 is provided at the bottom of the lifting plate 4, and a second sharp corner 11 is provided at the upper end of the transverse plate 6; when the lifting plate 4 is pulled down, the probability of the first sharp corner 10 and the second sharp corner 11 directly contacting each other is small, and the descending lifting plate 4 can directly squeeze the transverse plate 6 to both sides, without the operator manually moving the transverse plate 6, and the operation is more convenient.

[0037] Two symmetrically distributed first magnetic blocks 12 are fixed on both sides of the inclined plate 1, and a second magnetic block 13 is embedded on the outer side of the transverse plate 6 located at the edge position, and the first magnetic block 12 and the second magnetic block 13 at the corresponding position have the same poles facing each other; when in use, the repulsive force between the first magnetic block 12 and the second magnetic block 13 will push the transverse plate 6 at the edge toward the middle by a certain distance, thereby making the first sharp corner 10 and the second sharp corner 11 more likely to diverge from each other, thereby improving the smoothness of operation and the operator's experience.

[0038] A plurality of weight-reducing grooves 14 are provided above the inclined plate 1 ; the weight-reducing grooves 14 can reduce the weight above the inclined plate 1 , thereby lowering the center of gravity of the inclined plate 1 and further improving its stability.

[0039] The diagonal support rod 8 includes a support rod 801, the upper end of the support rod 801 is provided with a soft cover 802, and an arc-shaped clamping plate 803 is fixed below the support rod 801, and a plurality of arc-shaped grooves 804 matching the arc-shaped clamping plate 803 are opened on the lifting plate 4 and the transverse plate 6, and the arc-shaped clamping plate 803 is clamped in the arc-shaped groove 804; the support rod 801 lifts the arc-shaped clamping plate 803 upward under the action of its own gravity and the gravity of the test tube and firmly clamps it in the arc-shaped groove 804, and the arc-shaped clamping plate 803 can be detached from the arc-shaped groove 804 by rotating the support rod 801 upward, which is convenient for the operator to replace the support rods 801 of different lengths and expand the scope of application of the device.

[0040] In this embodiment, the above fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.

[0041] The working principle of this utility model:

[0042] When in use, the operator can put test tubes, beakers and other containers upside down on the support rod 801, among which heavier ones can be placed on the transverse plate 6, and lighter ones can be placed on the lifting plate 4, which increases the storage capacity while preventing the lifting plate 4 from sliding down due to excessive pressure, thereby improving the stability of the device. The water in the test tube will drip onto the lifting plate 4 or the transverse plate 6, and finally fall into the water receiving trough 903 along the inclined plate 1. Moreover, when taking and placing the test tubes on the lifting plate 4, they can directly slide downward along the vertical slide groove 2 toward the lifting plate 4. At this time, the first sharp corner 10 and the second sharp corner 11 squeeze each other, which will squeeze the transverse plates 6 on both sides of the lifting plate 4 to both sides, and then the lifting plate 4 can be pulled down, making it convenient to take and place materials. After taking and placing materials, the lifting plate 4 is reset upward, and the operator can easily take and place test tubes at high places, thereby increasing the height limit of the device and being able to place more test tubes. The tilting plate 1 can be supported by the tilting plate 1 and can provide a vibration buffer for the tilting plate 1 at the bend. When the tilting plate 1 is hit accidentally, it can shake slightly to reduce the risk of tipping over and improve the protection effect of the test tube. In addition, the repulsive force between the first magnetic block 12 and the second magnetic block 13 will push the edge of the transverse plate 6 to the middle by a certain distance, thereby making the first sharp corner 10 and the second sharp corner 11 more likely to diverge from each other, thereby improving the operation smoothness and the operator's experience. In addition, the support rod 801 will lift the arc clamping plate 803 upward under the action of its own gravity and the gravity of the test tube and firmly clamp it in the arc groove 804. The arc clamping plate 803 can be detached from the arc groove 804 by rotating the support rod 801 upward, which is convenient for the operator to replace the support rods 801 of different lengths and expand the scope of application of the device.

[0043] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
