[0025] Currently, the sizes of some crucible clamps are fixed and can only be applicable to crucibles with sizes adapted to them, with poor adaptability and unable to meet the usage requirements of crucibles of different sizes. And the crucible clamps with adjustable sizes, due to their adjustable design, are prone to the problem of insufficient clamping stability, resulting in a risk of tipping when clamping the crucible.
[0026] The present utility model provides a crucible clamp, which includes a handle 10, an adjustment assembly 20, two clamping rods 30 and two protection rods 40. The adjustment assembly 20 is connected to the handle 10. The adjustment assembly 20 includes a first telescopic rod 21, a second telescopic rod 22 and a connection structure 23. Both the first telescopic rod 21 and the second telescopic rod 22 are installed on the connection structure 23, and the second telescopic rod 22 is arranged at an upper and lower interval with the first telescopic rod 21. The connection structure 23 can adjust the vertical distance between the first telescopic rod 21 and the second telescopic rod 22. The two clamping rods 30 are respectively connected to both ends of the first telescopic rod 21. The two clamping rods 30 enclose a clamping space for clamping the crucible. The first telescopic rod 21 can telescopically move relative to the connection structure 23 to drive the two clamping rods 30 to approach or move away from each other in the horizontal direction. The two protection rods 40 are respectively connected to both ends of the second telescopic rod 22, and the two protection rods 40 are arranged in one-to-one correspondence with the two clamping rods 30. The second telescopic rod 22 can telescopically move relative to the connection structure 23 to drive the two protection rods 40 to approach or move away from each other in the horizontal direction.
[0027] Please refer to Figure 1 , the first telescopic rod 21 is located below the second telescopic rod 22. Both ends of the first telescopic rod 21 are respectively connected to the two clamping rods 30, and both ends of the second telescopic rod 22 are respectively connected to the two protection rods 40, so that the two protection rods 40 are arranged in one-to-one correspondence above the two clamping rods 30. By telescoping the first telescopic rod 21, the distance between the two clamping rods 30 is adjusted, so that the two clamping rods 30 respectively abut against both sides of the bottom of the crucible to clamp the crucible in the clamping space. By telescoping the second telescopic rod 22, the distance between the two protection rods 40 is adjusted, so that the two protection rods 40 respectively abut against both sides of the top of the crucible to provide lateral support for the crucible and keep the crucible stably clamped in the clamping space. By adjusting the distance between the first telescopic rod 21 and the second telescopic rod 22 through the connection structure 23, the vertical distance between the clamping rods 30 and the protection rods 40 is adjusted, so that the crucible clamp provided by the present utility model can adapt to crucibles of different heights.
[0028] For the crucible clamp provided by the present utility model, by connecting the two clamping rods 30 to both ends of the first telescopic rod 21 and connecting the two protection rods 40 to both ends of the second telescopic rod 22, so that the two protection rods 40 are arranged in one-to-one correspondence above the two clamping rods 30, and by providing support for both sides of the crucible through the two protection rods 40, the clamping stability is good, and the crucible can be effectively prevented from tipping during the process of clamping the crucible, playing a protective role. By telescoping the first telescopic rod 21, the distance between the two clamping rods 30 is adjusted, and by telescoping the second telescopic rod 22, the distance between the two protection rods 40 is adjusted, so that the crucible clamp can adapt to crucibles of different widths. By adjusting the vertical distance between the clamping rods 30 and the protection rods 40 through the connection structure 23, the crucible clamp can adapt to crucibles of different heights. The structure is simple and the adjustment is convenient, effectively improving the adaptability of the crucible clamp.
[0029] In one embodiment, the horizontal direction includes a first horizontal direction and a second horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, the first telescopic rod 21 and the second telescopic rod 22 both extend along the first horizontal direction, and the clamping rods 30 and the protection rods 40 both extend along the second horizontal direction; the first telescopic rod 21 can telescopically move relative to the connection structure 23 along the first horizontal direction to drive the two clamping rods 30 to approach or move away from each other along the first horizontal direction; the second telescopic rod 22 can telescopically move relative to the connection structure 23 along the first horizontal direction to drive the two protection rods 40 to approach or move away from each other along the first horizontal direction.
[0030] Please refer to Figure 1 , Figure 1 The front-back direction in Figure 1 is the first horizontal direction, Figure 1 the left-right direction in
[0031] is the second horizontal direction, and
[0032] the up-down direction in
[0033] is the vertical direction. The two clamping rods 30 are both vertically connected to the first telescopic rod 21, and the two protection rods 40 are both vertically connected to the second telescopic rod 22, so that the two clamping rods 30 and the two protection rods 40 are all parallel to each other, which can save the occupied space, is beneficial for the crucible clamp to extend into a narrow environment to clamp the crucible, and is convenient for accurately measuring and positioning the distance between the two clamping rods 30 and the two protection rods 40.
[0034] It should be noted that the two connecting blocks 232 are connected by a connecting member 231. By connecting the connecting blocks 232 to different positions on the connecting member 231, the distance between the two connecting blocks 232 can be changed, so as to adjust the distance between the first telescopic rod 21 and the second telescopic rod 22, enabling the crucible clamp proposed by the present utility model to adapt to crucibles of different height dimensions.
[0035] In an embodiment, the connecting member 231 is a screw rod, and threaded holes adapted to the screw rod are provided on each connecting block 232. Further, the two connecting blocks 232 are connected by the screw rod. By rotating the screw rod, the connection positions of the connecting blocks 232 with the screw rod can be controlled, which is convenient for adjustment and facilitates precise adjustment of the distance between the two connecting blocks 232.
[0036] In an embodiment, both the first telescopic rod 21 and the second telescopic rod 22 are multi-group telescopic structures composed of a plurality of hollow rods with gradually decreasing sizes nested together.
[0037] It can be understood that the telescoping of the first telescopic rod 21 and the second telescopic rod 22 is achieved by adjusting the nesting distance between two mutually nested hollow rods. The mutual nesting of a plurality of hollow rods can increase the length adjustment range of the first telescopic rod 21 and the second telescopic rod 22, thereby improving the adaptability of the crucible clamp. Both the first telescopic rod 21 and the second telescopic rod 22 are hollow structures, which can effectively reduce the weight of the first telescopic rod 21 and the second telescopic rod 22. In an embodiment, three mutually nested hollow rods are provided at both ends of the first telescopic rod 21 and both ends of the second telescopic rod 22.
[0038] In an embodiment, among the two mutually nested hollow rods, the end of the outer hollow rod protrudes inwards to form a first limiting convex ring, and the end of the inner hollow rod protrudes outwards to form a second limiting convex ring. The second limiting convex ring is used to abut against the first limiting convex ring. The first limiting ring and the second limiting ring can prevent the two mutually nested hollow rods from separating, and the structural stability is high.
[0039] In an embodiment, among the two mutually nested hollow rods, a locking hole for the locking rod to pass through is provided on the outer hollow rod, and the locking rod passes through the locking hole and abuts against the inner hollow rod.
[0040] It can be understood that when the two mutually nested hollow rods are telescoped to a preset position, the locking rod passes through the locking hole of the outer hollow rod and then abuts against the rod wall of the inner hollow rod to lock the outer hollow rod and the inner one together, so that the first telescopic rod 21 and the second telescopic rod 22 do not telescope during the process of clamping the crucible, ensuring stable clamping of the crucible clamp.
[0041] In an embodiment, the handle 10 is a multi-group telescopic structure composed of a plurality of hollow sleeves with gradually decreasing sizes nested together.
[0042] Understandably, by adjusting the connection position between any two mutually nested hollow sleeves, the length of the handle 10 can be adjusted, thereby improving the adaptability of the crucible clamp, and the handle 10 is telescopically arranged, which is convenient for storage and carrying.
[0043] In one embodiment, one end of the handle 10 is connected to the adjusting assembly 20, and a protective sleeve 11 is sleeved on the other end of the handle 10. It can be explained that the protective sleeve 11 is made of heat-insulating material. When the crucible clamp clamps the crucible in a high-temperature environment, the protective sleeve 11 can isolate the heat on the handle 10, prevent the operator's hand from being injured, and eliminate potential safety hazards.
[0044] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
