Detailed Description

The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the disclosure of the present invention, and are not intended to limit the scope of the invention, which is defined by the claims, but rather by the terms of modification, variation of proportions, or adjustment of sizes, without affecting the efficacy or achievement of the present invention, should be understood as falling within the scope of the present invention. Also, the terms such as "upper", "lower", "front", "rear", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for which the invention may be practiced or for which the relative relationships may be altered or modified without materially altering the technical context.

An operation table for dissecting mice as shown in fig. 1 to 3 and 14 to 16 comprises a table plate 1, four first arms 2, and one second arm 3.

The upper end surface of the platen 1 is provided with an annular groove 11 (the annular shape is not limited to an annular shape, and naturally includes a rectangular ring as shown in fig. 1 and 16), and the bottom surface of the groove 11 is provided with a through hole (in the drawings, only the length side of the groove 11 is provided with a through hole). The four corners of the bedplate can be provided with supporting legs to prop up the bedplate and then place a vessel under the bedplate for containing the flowing blood or cleaning sewage of the bedplate, or the vessel can be directly placed at the lower part of the bedplate and directly support the bedplate by means of the vessel. The middle region of the annular groove 11 is a place where the laboratory mice are placed.

The first supporting arm 2 comprises two (as shown in fig. 16) or four (as shown in fig. 1) first sliding blocks 21, four arm rods 22, four binding blocks 23, four binding ropes 24 and a fastening bolt 25. The arm rods 22, the binding blocks 23 and the binding ropes 24 are in one-to-one correspondence to form a group, and the fastening bolts 25 are consistent with the number of the first sliding blocks 21 and are in one-to-one correspondence to form a group.

As shown in fig. 1, when the number one slider 21 is provided with four, two screw rods 12 with axes along the front-rear direction are respectively provided on the left side and the right side of the lower end surface of the platen 1, and two screw rods 12 provided on two sides are provided on two sides near the front end side of the platen 1, and the other two screw rods are provided near the rear end side of the platen 1. The first sliding blocks 21 are matched with the screw rods 12 in a one-to-one correspondence. The outer end of each screw lever 12 is provided with a handle 13 in a matching way, and when the handle 13 is rotated, each first sliding block 21 can reciprocate along the front-back direction relative to the matched screw rod 12. One end of each arm 22 is correspondingly matched with each first slider 21 through the fastening bolt 25, the first sliders 21 which are relatively matched with each arm 22 can be rotated in the horizontal plane or fixed relative to the first sliders 21 through adjusting the fastening bolt 25, namely, the connection between each arm 22 and each first slider 21 can be relatively loosened through adjusting the fastening bolt 25, so that each arm 22 can be rotated relative to the first sliders 21, and conversely, the connection between each arm 22 and each first slider 21 can be relatively fixed through adjusting the fastening bolt 25, so that each arm 22 cannot be rotated relative to the first sliders 21.

As shown in fig. 2, the end of the screw rod of the fastening bolt 25 is provided with an external thread, the middle part is a light beam, the end close to the nut is provided with a shaft shoulder, and the shaft shoulder is provided with an elastic collar 251. The arm lever 22 is matched with the light column section of the fastening bolt 25, and the external thread section is connected with the first slider 21. When the fixing bolt 25 is screwed to screw out the outer thread section of the fixing bolt outwards relative to the first slider 2, the pressing force of the shoulder portion to the arm 22 is gradually reduced, and the arm 22 can be rotated to rotate relative to the first slider 21. On the contrary, when the fixing bolt 25 is screwed to rotate the outer thread section inwards relative to the first slider 2, the pressing force of the shoulder portion to the arm 22 is gradually increased, and finally the elastic ferrule 251 is deformed, so that the arm 22 and the first slider 21 are tightly pressed and connected into a relatively rigid whole, and the rotation of the arm 22 relative to the first slider 21 is prevented.

As shown in fig. 16, when two slide blocks 21 are provided, a screw rod 12 having an axis along the front-rear direction is provided on the left side and the right side of the lower end surface of the platen 1, and the screw rods 12 provided on both sides are simultaneously located on the rear end side of the platen 1, or may be simultaneously located on the front end side of the platen 1. The first sliding blocks 21 are matched with the screw rods 12 in a one-to-one correspondence. The outer end (rear end) of the screw lever 12 is provided with a handle 13 in a matching manner, and when the handle 13 is rotated, the first slider 21 can reciprocate along the front-rear direction relative to the matched screw rod 12. One end of each arm 22 is (rigidly) connected to the platen 1 (the length of each arm 22 is perpendicular to the left or right end of the platen 1 or forms an acute angle of not less than 80 degrees, in the figure, 90 degrees). One end of each of the other two arm rods 22 is matched with the first slider 21 through the fastening bolt 25, and the arm rods 22 can rotate in a horizontal plane relative to the first slider 21 or are fixed relative to the first slider 21 through adjusting the fastening bolts 25.

As shown in fig. 5 and 6, the end of the screw rod of the fastening bolt 25 is provided with an external thread, the middle part is a light column, the nut is sleeved with a spiral ring 26, the spiral ring 26 is matched with the nut of the fastening bolt 2 in a threaded structure, and an elastic washer 261 (made of elastic materials such as polyester materials and rubber materials) is fixedly arranged at the inner end of the spiral ring 26. The end surface of the arm 22 opposite to the elastic washer 261 is provided with a counter bore 223. The arm lever 22 is matched with the light column section of the fastening bolt 25, and the external thread section is connected with the first slider 21. When the screw 26 is screwed out to be screwed out with respect to the nut portion of the fixing bolt 25, the elastic washer 261 gradually moves out of the counterbore 223, and finally out of contact with the end face of the arm 22, thereby enabling the arm 22 to be rotated with respect to the first slider 21. On the contrary, when the screw ring 26 is screwed to rotate inwards relative to the fixing bolt 25, the elastic washer 261 is gradually pressed into the counter bore 223, and finally, pressure is applied to the end face of the arm 22, so that the arm 22 and the first slider 21 are tightly pressed and connected into a relatively rigid whole, and the rotation of the arm 22 relative to the first slider 21 is prevented. When the spiral ring 26 compresses the elastic washer 261, the free end surface of the nut of the fastening bolt 25 extends outwards by a certain length relative to the outer end surface of the spiral ring 26.

As shown in fig. 1, 14 and 15, the arm 22 is provided with a linear slot 221 along its length. The lower end of the binding block 23 is matched with the linear slot 221, and the binding block 23 can slide relative to the arm 22 by taking the linear slot 221 as a track, and can be fixed at any position of the linear slot 221 relative to the arm 22.

As shown in fig. 15, the binding block 23 includes a cylinder 23a, a pressing block 23b, a cap bar 23c, a spring 23d, and a rubber collar 23e. The rope grooves 231 and the grooves 232 are both arranged on the column 23 a. The lower end of the cylinder 23a is fitted into the linear slot 221 and the lower end passes through the lower end face of the arm 22. The lower end face of the cylinder 23a is provided with a threaded hole, the pressing block 23b is sleeved at the lower end of the cylinder 23a and can slide up and down relative to the cylinder 23a, and the lower end face of the pressing block 23b is provided with a counter bore. The spring 23d is disposed in a counterbore of the press block 23 b. The rod body of the cap rod 23c is provided with external threads and is matched with the threaded hole arranged on the column body 23 a. The outer diameter of the cap body of the cap rod 23c is not larger than the inner diameter of the counter bore on the pressing block 23 b. In the process of screwing the cap rod 23c into the threaded hole of the cylinder 23a, the spring 23d is compressed to press the pressing block 23b with upward pressure, and the upper end of the pressing block 23b is pushed toward the lower end face of the arm 22. The lower end surface of the arm 22 is provided with an elastic pad 222 (which may be made of an elastic polyester material or a rubber material) at the periphery of the linear slot 221. The upper end surface of the pressing block 23b is fixedly provided with a tooth surface plate 233, and the plate teeth of the tooth surface plate 233 face the elastic pad 222. When the spring 23d pushes the pressing block 23b upward, the plate teeth of the tooth surface plate 233 are pressed into the elastic pad 222, so that the binding block 23 can be fixed relative to the arm 22. When the pressing block 23b is pulled downward, the tooth surface plate 233 is separated from the elastic pad 222, so that the binding block 23 can move along the linear slot 221 relative to the arm 22. Therefore, in order to increase the friction between the hand and the annular surface of the pressing block 23b when the pressing block 23b is pulled downward, an annular groove body is arranged on the annular surface of the pressing block 23b, and the rubber collar 23e is embedded in the groove body. The pre-tightening pressure of the spring 23d can be adjusted by adjusting the length of the rod body of the cap rod 23c screwed into the threaded hole at the end of the cylinder 23 a. The axial length of the threaded hole at the end of the cylindrical body 23a is long enough to be at least not smaller than the axial length of the rod body portion on the cap rod 23 c.

As shown in fig. 14 to 16, the rope groove 231 is formed in the rope block 23, the rope groove 231 extends vertically downward from a position of the upper end surface of the rope block 23, which is deviated from the center, then extends obliquely toward the center, and finally extends vertically downward along the center, and a groove 232 is formed at the side of the lowermost end of the rope groove 231.

As shown in fig. 2, one end of the rope 24 is provided with a knot 241, and the other end is provided with a retractable buckle 242. The nubs 241 can snap into the grooves 232 on the tuft block 23.

In use, one end provided with the cuff 242 is sleeved on the limb of a laboratory mouse, and the cuff is tightened to shrink and firmly bind the limb of the laboratory. The middle part of the binding rope is then inserted into the rope groove 231 up to the bottom of the rope groove 231. Finally, the binding block 23 is moved outwards along the linear slot 221 of the arm 22 until the binding rope 24 is tensioned, at which time the nubs 241 of the binding rope 24 are caught in the grooves 232 of the binding block 23. The bulk of nub 241 is designed to ensure that nub 241 is securely captured within groove 232 and does not move out of the groove 231 from the mouth of rope groove 231 when rope 24 is tensioned.

The first supporting arm 2 (i.e. the arm lever 22) arranged at the front end or the rear end or at the front end and the rear end of the bedplate 1 can linearly reciprocate in the front-rear direction, so that the design scheme of the patent can adapt to experimental mice with different sizes (refer to body lengths). In principle, the height of the upper end surface of the arm 22 of the first arm 2 is adapted to the height of the upper end surface of the table plate 1, and a large height difference cannot be obtained, but the specific height difference is also required to be determined according to the lowest groove-shaped position of the rope groove 231 provided on the beam block 23 (the lower end position of the rope groove 231 is above the upper end surface of the arm 22).

As shown in fig. 4 and 5, the arm 22 includes a first member 22a and a second member 22b. The first component 22a is L-shaped, the first component 22a is connected with the first slider 21 in a matching way, and the second component 22b is matched with the first component 22a through a linear rail which is arranged on the end face of the free end of the first component 22a and extends along the vertical direction. The second member 22b is vertically slidable with respect to the first member 22 a. The linear slot 221 is provided in the second member 22b.

The above design of the arm 22 structure enables the part (i.e. the second part 22 b) provided with the beam block 23 to be lifted in the vertical direction, so as to adjust the height position of the lowest end of the rope groove 231 according to the size (refer to the obesity degree) of the laboratory mouse, thereby ensuring that the laboratory mice with different obesity degrees can obtain the best fixing posture, and being beneficial to improving the firmness of binding and fixing the laboratory mouse.

As shown in fig. 1 and 16, one end of the second arm 3 is connected to the middle part of the front end of the platen 1, and the length direction of the second arm 3 is identical to the length direction of the platen 1. In the illustration, a clamping block 14 is further installed at the rear end of the upper end face of the bedplate through a chute structure, a sponge layer 141 is fixedly arranged on the upper end face of the clamping block 14, and a height difference within +/-3 mm exists between the upper end face position of the sponge layer 141 and the upper end face position of the bedplate 1. The upper end surface position of the second arm 3 is also within + -3 mm from the upper end surface position of the platen 1. Along the length direction of second arm 3, in the left side alternate distribution of second arm 3 is provided with a plurality of connection fixture blocks 32, be equipped with the band 31 of elastic material preparation on the connection fixture block 32, the one end of band 31 is connected connection fixture block 32, the other end can by the up end of second arm 3 is passed through behind the lower terminal surface of second arm 3 operatively insert and connect on the connection fixture block 32. The second supporting arm 3 can operatively fix the tail of the laboratory mouse by means of the binding band 31 and the connecting clamping block 32 arranged thereon. The plug structure of the strap 31 and the connecting fixture block 32 can refer to the plug structure of the strap connection used on the backpack.

The construction of the arm 22 is modified as follows to enable it to be folded and collapsed for storage and portability.

As shown in fig. 7 to 9, the arm lever 2 includes a first member 22c and a second member 22d. The first member 22c is L-shaped, the first member 22c is connected to the first slider 21 in a matching manner, and the linear slot 221 is formed in the second member 22d. The free end face of the first member 22c is provided with a shaped groove 224. One end of the second member 22d is inserted into the shaped slot 224 and pivotally mates with the first member 22 c. The second member 22d can be rotated downward at least 90 degrees relative to the first member 22 c. A first plate 225 is fitted to the upper side of the outer end surface of the groove 224, and a second plate 226 is fitted to the upper part of the end of the second member 22d pivotally connected to the first member 22 c. When the second member 22d rotates upward to a horizontal position relative to the first member 22c (with reference to the upper end surface of the second member 22 d), the first plate 225 is connected to the second plate 226, so that the first member 22c is integrally connected to the second member 22d. The first plate 225 can be disconnected from the second plate 226 when a downward torque is applied to the second member 22d. The connection between the first plate 225 and the second plate 226 can be by magnetic force attraction connection or by clamping grooves.

The second arm 3 is also folded for storage and carrying, and its structure is modified as follows.

The connecting plate 4 is fixedly installed on the lower end face of the bedplate 1, and one end face of the connecting plate 4 extends outwards relative to the front end face or the rear end face of the bedplate 1. The second slide block 5 is matched with the end surface of the connecting plate 4 extending out of the bedplate 1 through a linear track extending in the vertical direction, so that the second slide block 5 can slide up and down relative to the connecting plate 4. The track length of the No. two slider 5 is greater than the track length of the web 4, and in some embodiments the length of the former is 3 to 6 times the length of the latter. As shown in fig. 10, the length of the track on the connecting plate 4 extends through the thickness of the track, and the length of the track of the second slider 5 also extends through the whole thickness of the track. In the state shown in fig. 10, the upper end surface of the second slider 5 is higher than the upper end surface of the connecting plate 4. One end (inner end surface) of the second sliding block 5 facing the bedplate 1 is provided with a U-shaped groove, and an opening of the U-shaped groove faces the bedplate 1. The two side wall surfaces of the U-shaped groove are provided with linear grooves 51, and the linear grooves 51 extend along the horizontal plane. One end of the second supporting arm 3 is provided with a shaft 33, one end provided with the shaft 33 is inserted into the U-shaped groove from the lower part of the outer end surface of the second sliding block 5, and two ends of the shaft 33 extend into linear grooves 51 arranged on two side wall surfaces of the U-shaped groove, so that the second supporting arm 3 can slide in a horizontal plane. Ribs 52 are respectively arranged on two side wall surfaces of the U-shaped groove, and the linear grooves 51 arranged on the same side opposite to the ribs 52 are closer to the notch of the U-shaped groove. The two ribs 52 are provided with opposite semi-cylindrical grooves 521. The end of the second supporting arm 3 provided with the shaft 33 is provided with a clamping column 34, and the clamping column 34 is correspondingly matched with the semi-column groove 521. When the second arm 3 is pushed horizontally to the platen 1 side, the locking post 34 can be locked into the half-column groove 521 provided on the same side to position the second arm 3 in the horizontal plane (with reference to the upper end surface of the second arm 3). Pulling the second arm 3 outward (right side in fig. 12) can move the clip 3 out of the half-column groove 521, and the second arm 3 can rotate downward at this time. As shown in fig. 13, the second slider 5 is pushed down to make its upper end correspond to the connection board 4, so that the second supporting arm 3 can be folded under the connection board 4, and the second supporting arm 3 is pulled horizontally to the left side, so that the clamping post 34 is clamped into the half-column groove 521 provided on the same side to position the second supporting arm 3. In some embodiments, the clamping post 34 is prismatic (e.g. plate-shaped), and correspondingly, the half-prism-shaped groove 521 is a half-prism-shaped groove (e.g. bar-shaped) to ensure that the purpose of preventing the second supporting arm 3 from rotating relative to the platen 1 is better achieved after the clamping post 34 is combined with the half-prism-shaped groove 521.
