Description

Technical Field

[0001] This application relates to the field of clamping devices, and more particularly to a device for clamping small samples in laboratory heat treatment. Background Art

[0002] When laboratories process samples, heat treatment is usually used. Currently, manual clamping is commonly used to place or remove samples. Since some specimens are large and heavy, manual holding of the fixture during furnace loading is likely to cause hand sprains, and it is inconvenient to clamp out during furnace unloading, resulting in risks such as burns. Due to the heavy specimens, when loading and unloading the furnace, due to limited manpower, it is easy to rehandle and reposition, causing bumps and scratches on the furnace body. The removed samples need to be placed on a tray to avoid damage. However, if the tray is placed in advance, it is necessary to prevent people from walking and stepping on the tray, which affects the operation of personnel. Without affecting the removal operation, it is not easy to place the tray.

[0003] Therefore, a device for clamping small samples in laboratory heat treatment that facilitates the placement of the tray is needed. Summary of the Utility Model

[0029] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] Refer to Figures 1-5, A device for clamping small samples in laboratory heat treatment, comprising: a trolley, a bracket 101, a connecting rod 102, a fixture 103, and a tray plate 104. Two moving wheels 105 are rotatably connected to the trolley. A foot lever 106 passing through the bracket 101 is fixedly connected to the center position of the moving wheel 105, and a foot part 107 is provided on the foot lever 106. Through the foot part 107, it is convenient to fix the trolley during clamping. There are two brackets 101, and the two brackets 101 are fixedly arranged on both sides of the trolley. Two vertically extending sliding grooves 108 are provided on the bracket 101. Two T-shaped rods 109 are fixedly connected to the tray plate 104. The cross-section of the sliding groove 108 is a T-shaped structure, and the T-shaped rods 109 are embedded in the sliding grooves 108. A connecting column 110 is fixedly connected to the bottom of the tray plate 104. A connecting head 111 is sleeved on the connecting column 110. An articulated rod 112 is hinged on the trolley, and one end of the articulated rod 112 is rotatably connected to the connecting head 111. Through the up and down movement of the T-shaped rods 109 in the sliding grooves 108, the tray plate 104 has a placement state and a storage state. In the placement state, the T-shaped rods 109 move to the bottom position of the sliding grooves 108, and the tray plate 104 is in a horizontal state, and the tray plate 104 is supported by the articulated rod 112; when in the storage state, the tray plate 104 is in a vertical state, and the T-shaped rods 109 move to the top position of the sliding grooves 108. The specimens after being taken out of the furnace can be directly placed on the tray plate 104 under the trolley, which can avoid unnecessary damage.

[0031] In one embodiment, the connecting head 111 includes: a sleeve part 113 and a cylindrical part 114. The sleeve part 113 is sleeved on the connecting column 110. When the tray plate 104 is being stored, the sleeve part 113 can slide and rotate on the connecting column 110. Fixed on the sleeve part 113, an installation hole 115 is provided at one end of the articulated rod 112, and the cylindrical part 114 is inserted into the installation hole 115 for connection.

[0032] In one embodiment, a mounting shaft part 116 is fixedly connected to the connecting rod 102. A through hole for the mounting shaft to pass through is provided on the fixture 103. The mounting shaft part 116 has a threaded end, and a nut 117 is installed on the threaded end. So that the fixture 103 can rotate around the mounting shaft part 116. At the same time, by removing the nut 117, the fixture 103 can be replaced, which is convenient for clamping samples of different specifications. The fixture 103 can be rotated and adjusted along with the connecting rod 102. In cooperation with the lifting of the connecting rod 102, it can be placed in multiple directions and at multiple angles, and the force can be well controlled. The fixture 103 can also deflect left and right around the mounting shaft part 116 on the connecting rod 102. During the quenching process, it can be stuck on the cooling groove, and the fixture 103 can use the mounting shaft part 116 as a fulcrum for quenching.

[0033] In one embodiment, an adjustment slot 118 is formed in the bracket 101. Both ends of the connecting rod 102 pass through the two adjustment slots 118 respectively. An adjustment block 119 located in the adjustment slot 118 is rotatably connected to the connecting rod 102. A threaded hole 120 is formed in the adjustment block 119. A plurality of positioning holes 121 vertically distributed are formed in the support rod. A bolt 122 is fixedly connected in the threaded hole 120. The bolt 122 passes through the positioning hole 121 to position the adjustment block 119. By inserting the bolt 122 into different positioning holes 121, it is convenient to adjust the height of the connecting rod 102 and facilitate multi-angle clamping.

[0034] In one embodiment, the T-shaped rod 109 includes a vertical rod portion 123 fixedly connected to the tray plate 104 and a horizontal rod portion 124 embedded in the sliding slot 108. A limiting through slot 125 is formed on one side of the sliding slot 108. A foot pedal 126 that passes through the limiting through slot 125 and is slidably matched with the limiting through slot 125 is rotatably connected to the horizontal rod portion 124. A locking plate 127 is slidably connected to the foot pedal 126. An elastic member 128 is arranged between the locking plate 127 and the foot pedal 126. A locking protrusion 129 is arranged on one side of the locking plate 127. A plurality of card slots 130 for the locking protrusion 129 to be embedded are vertically distributed on the bracket 101. When it is necessary to adjust the tray plate 104 to the placement state, by pulling the locking plate 127, the locking protrusion 129 is no longer embedded in the card slot 130. By pressing the foot pedal 126, the T-shaped rod 109 moves to the bottom position of the sliding slot 108, and the tray plate 104 is in a horizontal state.
