Technical Field

[0001] This utility model relates to the technical field of burette holders, and in particular to a burette holder for oilfield water quality analysis. Background Technology

[0002] In the field of oilfield water quality analysis, titration analysis, as a classic and precise chemical analysis method, is widely used to determine the concentration of various ions and pH in water samples, as well as to determine whether the water quality meets specific production or environmental protection standards. During titration, the burette is the core tool, and its stability, accuracy, and ease of operation directly affect the reliability of the analytical results; therefore, a burette rack is required to fix it in place.

[0003] Currently, among existing burette racks, such as the patent with authorization announcement number CN213078524U, this utility model belongs to the field of titration experimental technology and relates to a laboratory burette rack, including a butterfly clip set on a fixed rod for holding the burette. The fixed rod is provided with a support leg, and the bottom of the support leg is provided with a magnet. The butterfly clip is arranged opposite to the fixed rod and the support leg on the opposite side.

[0004] However, during use, it was found that the burette holder was not very convenient to store, which increased its space occupation, and the butterfly clips were not very reliable in fixing the burettes, which reduced the effectiveness of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a burette holder for oilfield water quality analysis that improves the clamping firmness and ease of clamping operation of burettes and enhances the storage convenience of burette holders.

[0006] This utility model discloses a burette holder for oilfield water quality analysis, comprising a base and a slider, with the slider mounted on the base; it also includes a pushing device, a supporting device, a guide, a first clamping member, and a second clamping member. The guide is mounted on the outer wall of the slider, the first clamping member is fixedly mounted on the guide, and the second clamping member is slidably mounted on the guide. The pushing device is disposed on the guide and provides a pushing force to the second clamping member. The supporting device is disposed on the base and is used to support and adjust the slider. The burette is placed between the first and second clamping members. The pushing device provides a pushing force to the second clamping member, causing the second clamping member to cooperate with the first clamping member to clamp and fix the burette, improving the clamping firmness and ease of clamping operation. The supporting device allows for the adjustment of the slider's height, improving the ease of adjusting the burette's height. After use, the slider is folded to one side using the supporting device, thereby reducing the height of the burette holder and improving its ease of storage.

[0007] Preferably, the support device includes a base, a housing, a guide cylinder, a pin, a first rotating shaft, a first spring, and a guide post. The base is rotatably mounted on the outer wall of the base, the housing is mounted on the outer wall of the base, the guide cylinder is mounted on the outer wall of the housing, the pin is slidably mounted on the guide cylinder, the first rotating shaft is rotatably mounted inside the housing and is concentrically connected to the base, the first rotating shaft has a groove, the lower part of the pin extends into the groove, the first spring is fitted onto the outer wall of the pin and is located inside the guide cylinder, the guide post is mounted on the outer wall of the base, and the slider is slidably mounted on the guide post. By rotating the base, the guide post is adjusted to a vertical angle, which facilitates the support and fixation of the burette. At this time, the first spring provides a downward pushing force to the pin, causing the lower part of the pin to extend into the groove and lock the rotation of the first rotating shaft, thereby positioning the base. After the burette rack is used, by moving the pin upward to separate it from the groove and rotating the base backward, the base drives the guide post to swing and rotate backward, thereby retracting the slider and improving the convenience of the storage operation.

[0008] Preferably, the pushing device includes a push rod, a first connecting member, a second connecting member, a telescopic rod, and a second spring. The push rod slides through the guide member and the first clamping member and connects to the second clamping member. The first connecting member is installed at the end of the push rod, the second connecting member is installed on the outer wall of the guide member, the telescopic rod is installed between the second clamping member and the guide member, and the second spring is fitted onto the telescopic rod. The second spring provides a pushing force to the second clamping member, causing the second clamping member to move closer to the first clamping member to clamp and fix the burette. When it is necessary to loosen the burette, the operator presses the first connecting member and the second connecting member in opposite directions, thereby causing the first connecting member to drive the second clamping member to move in the opposite direction via the push rod, so that the first clamping member and the second clamping member loosen the burette, improving the convenience of one-handed operation.

[0009] Preferably, the device further includes a damping liquid cylinder, a second rotating shaft, and multiple sets of blades. The damping liquid cylinder is installed on the outer wall of the base. The second rotating shaft is rotatably installed inside the damping liquid cylinder and concentrically connected to the base. Multiple sets of blades are installed on the outer wall of the second rotating shaft, and through holes are provided on the multiple sets of blades. Damping liquid is provided inside the damping liquid cylinder. When the base rotates, it drives the second rotating shaft to rotate. After the second rotating shaft rotates, it drives the multiple sets of blades to move circumferentially. At this time, the damping liquid passes through the multiple sets of through holes on the blades, causing them to generate movement resistance, thereby damping the rotation of the base and improving the stability of the base rotation.

[0010] Preferably, it also includes a set screw, which is fitted onto the slider; by rotating the set screw, the guide post is tightened, thereby improving the sliding positioning convenience of the slider.

[0011] Preferably, it also includes a support member, which is installed on the outer wall of the base; when the base drives the guide column to swing and rotate backward for storage, the support member supports and fixes the guide column, improving the stability of the guide column after storage.

[0012] Preferably, the outer walls of the first and second clamping members are provided with anti-slip pads to improve the firmness of the first and second clamping members in holding the burette.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the burette is placed between the first clamping member and the second clamping member, and the second clamping member is pushed by the pushing device, so that the second clamping member cooperates with the first clamping member to clamp and fix the burette, thereby improving the clamping firmness and clamping operation convenience of the burette. The slider is raised and lowered by the support device, thereby improving the convenience of adjusting the height of the burette. After the burette rack is used, the slider is stored to one side by the support device, thereby reducing the height of the burette rack and improving the storage convenience of the burette rack.
