Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically a fixing device suitable for various sizes and types of glass containers. Background Technology

[0002] Various glass containers are frequently used in experiments, including flat-bottomed containers (volume flasks, beakers, Erlenmeyer flasks) and non-flat-bottomed containers (round-bottom flasks, heart-shaped flasks). Volume flasks with small bottoms are prone to tipping over, posing a safety hazard and wasting reagents. Non-flat-bottomed containers also require stability when adding reagents. Furthermore, many experiments involve ultrasonic or water bath heating during sample pretreatment. Due to buoyancy, most glass containers, even flat-bottomed ones, are highly susceptible to tipping. Current technologies typically use a single fixing device that can only hold one type of container, failing to accommodate multiple types simultaneously. This results in low efficiency and poor versatility for glass container racks. Therefore, a fixing device suitable for multiple types of glass containers is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a fixing device suitable for glass containers of various specifications and types. This solves the problem that existing fixing devices can only fix one type of glass container and cannot be compatible with multiple glass containers at the same time, resulting in low efficiency and poor versatility of glass container racks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixing device suitable for various sizes and types of glass containers includes a support frame, a base fixed to the top of the support frame, multiple fixing holes provided on the base, a fixing rod detachably connected to the fixing holes at the bottom end, and an iron clamp detachably connected to the fixing rod. The iron clamp is detachably connected to the fixing rod via a cross clamp.

[0006] Furthermore, the support frame includes a base plate, an outer sleeve fixed to the base plate at its bottom end, and an inner sleeve slidably connected to the outer sleeve at its bottom end. The outer sleeve has multiple external insertion holes distributed axially along the outer sleeve. The inner sleeve has an internal insertion hole, which is directly opposite to the external insertion hole. The internal insertion hole and the external insertion hole are connected by a T-shaped pin. The top end of the inner sleeve is fixedly connected to a base.

[0007] Furthermore, the cross clamp includes a connected arc-shaped groove one and an arc-shaped groove two, a tightening bolt one with one end screwed into or out of arc-shaped groove one, and a tightening bolt two with one end screwed into or out of arc-shaped groove two. The groove openings of arc-shaped groove one and arc-shaped groove two have different orientations.

[0008] Furthermore, the iron clamp includes a clamping rod, a clamping plate one fixed at one end to the clamping rod, and a clamping plate two positioned opposite the clamping plate one. The middle parts of the clamping plate one and the clamping plate two are rotatably connected by a rotating shaft. A torsion spring is sleeved on the rotating shaft, and the beginning and end of the torsion spring abut against the clamping plate one and the clamping plate two, respectively.

[0009] Furthermore, the first clamping plate is provided with an arc-shaped clamping groove, and the second clamping plate is provided with an arc-shaped clamping groove. The arc-shaped clamping groove and the arc-shaped clamping groove together form a circular clamping space.

[0010] Furthermore, the base is provided with a groove, and multiple fixing holes are distributed in a matrix at the bottom of the groove.

[0011] Furthermore, the fixing hole is provided with an internal threaded hole, and the bottom end of the fixing rod is provided with an external thread that matches the internal threaded hole.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, the fixing rod and the base are connected by threads. This detachable connection allows the size of the area enclosed by the fixing rod to be adjusted according to actual needs, meeting the fixing requirements of glass containers of different sizes or types of the same kind. The fixing holes on the base are arranged in a multi-hole matrix, enabling the device to fix multiple or various types of glass containers simultaneously, improving the device's performance and flexibility, and overcoming the shortcomings of existing fixing devices that can only fix a single object and have a narrow range of applications. The addition of detachable iron clamps to the fixing rod solves the problem of unstable fixing of the fixing rod for narrow-necked glass containers, expanding the device's application range. The support frame adopts an inner and outer sleeve and T-shaped pin design, which can flexibly adjust the height of the support frame to meet the water level requirements of glass containers of different heights during ultrasonic or water bath processes, further improving the device's applicability. This utility model solves the problem that existing fixing devices can only fix one type of glass container of one specification, and cannot be compatible with multiple glass containers at the same time, resulting in low efficiency and poor versatility of glass container racks.

[0021] like Figure 1-5 As shown, a fixing device suitable for various sizes and types of glass containers includes a support frame 1, a base 2 fixed to the top of the support frame 1, a plurality of fixing holes 21 provided on the base 2, a fixing rod 3 detachably connected to the fixing holes 21 at the bottom end, and an iron clamp 4 detachably connected to the fixing rod 3. The iron clamp 4 is detachably connected to the fixing rod 3 by a cross clamp 5.

[0022] In use, select appropriate hole positions according to the bottom size of the glass container, connect the four fixing rods 3 into the fixing holes 21 of the base 2, and then place the glass container in the area enclosed by the four fixing rods 3 to prevent the glass container from sliding and tipping over during ultrasonic or water bath heating. For glass containers with narrow necks, first adjust the height of the iron clamp 4 on the fixing rod 3 using the cross clamp 5, and then clamp the iron clamp 4 onto the neck of the glass container to carry out the experiment. This utility model solves the problem that in the prior art, one fixing device can only fix one type of glass container of one specification, and cannot be compatible with multiple glass containers at the same time, resulting in low efficiency and poor versatility of the glass container rack.

[0023] like Figure 1-5 As shown, the support frame 1 includes a base plate 11, an outer sleeve 12 with its bottom end fixed to the base plate 11, and an inner sleeve 13 with its bottom end slidably connected to the outer sleeve 12. The outer sleeve 12 has multiple external insertion holes 121 axially distributed along the outer sleeve 12. The inner sleeve 13 has an internal insertion hole directly opposite the external insertion holes 121. The internal insertion hole and the external insertion holes 121 are connected by a T-shaped pin 14. The top end of the inner sleeve 13 is fixedly connected to a base 2. In this embodiment, by adjusting the alignment...

[0024] The relative positions of the external insertion hole 121 and the internal insertion hole are determined by using a T-shaped pin 14 to connect the external insertion hole 121 and the internal insertion hole, thereby adjusting the experimental height of the base 2.

[0025] like Figure 1-5 As shown, the cross clamp 5 includes a connected arc-shaped groove 51 and an arc-shaped groove 52, a tightening bolt 53 with one end screwed into or out of the arc-shaped groove 51, and a tightening bolt 54 with one end screwed into or out of the arc-shaped groove 52. The openings of the arc-shaped groove 51 and the arc-shaped groove 52 face different directions. In this embodiment, the fixing rod 3 is inserted from the opening of the arc-shaped groove 51, and the fixing rod 3 is pressed against the arc-shaped groove 51 by gradually screwing one end of the tightening bolt 53 into the arc-shaped groove 51, so that the cross clamp 5 and the fixing rod 3 are detachably connected.

[0026] like Figure 1-5 As shown, the iron clamp 4 includes a clamping rod 41, a clamping plate 42 fixed at one end to the clamping rod 41, and a clamping plate 43 opposite to the clamping plate 42. The middle parts of the clamping plate 42 and the clamping plate 43 are rotatably connected by a rotating shaft 44. A torsion spring 45 is sleeved on the rotating shaft 44. The beginning and end of the torsion spring 45 abut against the clamping plate 42 and the clamping plate 43, respectively. In this embodiment, the clamping rod 41 is inserted into the groove of the arc-shaped groove 52. By tightening one end of the bolt 54, it is gradually screwed into the arc-shaped groove 52, and the clamping rod 41 is pressed against the arc-shaped groove 52. The iron clamp 4 can then be connected to the cross clamp 5. The beginning and end of the torsion spring 45 abut against the clamping plate 42 and the clamping plate 43, respectively, so that the neck of the narrow glass container can be clamped by the clamping plate 42 and the clamping plate 43.

[0027] like Figure 1-5 As shown, the clamping plate 42 is provided with an arc-shaped clamping groove 421, and the clamping plate 43 is provided with an arc-shaped clamping groove 431. The arc-shaped clamping groove 421 and the arc-shaped clamping groove 431 together form a circular clamping space. In this embodiment, the circular clamping space formed by the arc-shaped clamping groove 421 and the arc-shaped clamping groove 431 can completely fit the bottleneck of the glass container with a circular cross-section, resulting in a better clamping effect.

[0028] like Figure 1-5 As shown, the base 2 is provided with a groove 22, and multiple fixing holes 21 are distributed in a matrix at the bottom of the groove 22. In this embodiment, when multiple fixing holes 21 are distributed in a matrix, the principle of fixing a glass container by forming a square area with four fixing rods 3 is followed. First, according to the size of each glass container to be fixed, multiple fixing rods 3 are connected to the appropriate fixing holes 21 in sequence. Then, the glass container is placed in the fixing area that matches its own size, which can better prevent the glass container from tipping over or sliding during the experiment.

[0029] like Figure 1-5 As shown, the fixing hole 21 is provided with an internal threaded hole, and the bottom end of the fixing rod 3 is provided with an external thread that matches the internal threaded hole; in this embodiment, the fixing rod 3 is connected by the internal threaded hole and the external thread, making it easier to install and remove.
