Description

Technical Field

[0001] The utility model relates to the technical field of eyewash height fixing, in particular to a lifting clamp. Background Art

[0002] An eyewash station lift clamp is a lifting device used to secure the eyewash station. It typically consists of an adjustable clamp and screw mechanism that allows for adjustment of height as needed, ensuring the eyewash station remains securely in place during use. This lift clamp allows users to adjust the height of the eyewash station to suit different usage scenarios and personal needs, providing a more convenient eyewash experience.

[0003] For example, the clamping clamp or pipe clamp disclosed in publication number CN101317033A has a deformable, generally cylindrical housing with at least one longitudinal groove. Regions of the housing that are opposite each other along the longitudinal groove are configured as curved butt-jointed pieces. The butt-jointed pieces are configured to accommodate a hollow bolt. The housing can be clamped using a clamping screw that passes transversely through the hollow bolt and is arranged approximately tangentially to the housing, and a nut that can cooperate with the clamping screw in the hollow bolt. At least one clamping screw is directly or indirectly connected to a handle for manually clamping the clamping clamp or pipe clamp and / or operating the clamping screw.

[0004] The clamping clamp or pipe clamp mentioned above is used to accommodate the hollow bolt through the butt-jointed piece structure, which can be firmly fixed. However, when the eyewash station is fixed in use, the height of the eyewash station cannot be adjusted. If the space height on site is not enough, it cannot be used. Utility Model Content

[0005] The purpose of the present invention is to provide a lifting clamp to solve the problem in the background art that the height of the eyewash station cannot be adjusted when the eyewash station is fixed, and the eyewash station cannot be used if the height of the space on site is insufficient.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a lifting clamp, comprising a main body tube and a telescopic tube installed through the upper end of the main body tube, wherein a threaded connection section is provided on the outer side of the upper end of the main body tube, and the inner lower end of the locking nut is threadedly connected to the upper end of the main body tube through the threaded connection section;

[0007] The upper end of the main body tube is provided with a locking washer, and the locking washer is located between the locking nut and the telescopic tube, and the lower end of the telescopic tube is provided with a stable pressing mechanism;

[0008] The outer bolt of the main tube is equipped with a fixing chamber, and an elastic airbag is fixedly installed inside the fixing chamber, and a pressing block is fixedly installed inside the elastic airbag, and a secondary stabilizing and anti-skid mechanism is provided on the outer side of the pressing block.

[0009] Furthermore, the outer diameter of the telescopic tube is smaller than the inner diameter of the main body tube, and the shapes of the telescopic tube and the main body tube are both cylindrical.

[0010] Furthermore, the stable pressing mechanism is provided with a tightening socket, and the tightening socket is opened at the upper end of the locking nut, and the number of the tightening sockets is four, and a knob rod is provided inside the tightening socket.

[0011] Furthermore, the lower end of the locking pad is conical, and a longitudinal opening is provided on the right side of the locking pad.

[0012] Furthermore, the secondary stabilization and anti-slip mechanism is provided with a limit groove, and the limit groove is opened on the inner wall of the fixed bin, and the limit blocks are fixedly installed at the upper and lower ends of the pressure block, and the connection method between the limit block and the limit groove is a sliding connection, and an elastic rope is fixedly installed between the limit block and the fixed bin.

[0013] Furthermore, the shape of the pressing block is inclined, and the upper end of the pressing block corresponds to the lower end of the telescopic tube, and the pressing block and the elastic airbag form a pressed structure.

[0014] Furthermore, an air guide hose is installed through the right side of the elastic airbag, and an inflatable cushion is installed through the upper end of the air guide hose, and the shape of the inflatable cushion is cylindrical, and the outer side of the inflatable cushion is fixedly installed on the inner wall of the main body tube, and an anti-slip pad is fixedly installed on the inner side of the inflatable cushion, and the inner side of the anti-slip pad corresponds to the outer wall of the telescopic tube, and the shape of the anti-slip pad is cylindrical.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The outer diameter of the telescopic tube is smaller than the inner diameter of the main tube. The telescopic tube can be embedded in the interior of the main tube, so it can support the eyewash station, making it easier for staff to use the eyewash station. At the same time, the dual pipe setting of the main tube and the telescopic tube improves the structural strength of the device and prevents the clamp from being easily damaged;

[0017] Furthermore, the upper end of the main tube is provided with a threaded locking washer that cooperates with the locking nut, which is tapered and has an opening; the side surface of the locking nut is provided with four tightening holes with a diameter of 6.5mm. The outer diameter of the telescopic tube passes through the locking nut and the locking washer and enters the inner hole of the main tube. The upper end surface of the inner part of the locking nut contacts the upper end surface of the locking washer, and the tapered lower end of the locking washer is inserted into the inner hole of the main tube. When the locking nut is screwed into the main tube thread, the upper end surface of the locking washer is pressed downward by the locking nut. Because the lower end of the locking washer is tapered, due to the principle of force decomposition, the force on the locking washer is decomposed into a downward force and a force perpendicular to the central axis. Under the action of the decomposed force, and because the locking washer has a longitudinal opening, the diameter of the locking washer tends to become smaller, and the inner surface of the locking washer hugs the telescopic tube, so that the position of the telescopic tube is fixed, which can achieve a stable fixation effect;

[0018] Furthermore, when adjusting the height, insert the 6mm diameter knob rod into the tightening socket on the locking nut, rotate it counterclockwise to loosen the locking nut, then insert or pull the telescopic tube downward or upward to reach the desired height, and then rotate the locking nut clockwise to secure the telescopic tube. This achieves the effect of adjustable lifting height, which is convenient for staff to use.

[0019] 2. When adjusting the height, if the telescopic tube is inserted into the main tube, the bottom of the telescopic tube is squeezed. Due to its own tilt, the pressing block moves along the limit groove toward the inside of the fixed compartment through the limit block when squeezed by the telescopic tube, simultaneously squeezing the elastic airbag and stretching the elastic cord. At this time, the elastic airbag is squeezed and the air inside is transported to the inflatable cushion through the air guide hose. The inflatable cushion receives the air and expands. The expanded inflatable cushion pushes the anti-slip pad to squeeze the telescopic tube, ensuring the coaxiality of the telescopic tube and the main tube.

[0020] Furthermore, when the telescopic tube is pulled out, the telescopic tube stops squeezing the pressing block, and the limit blocks at the upper and lower ends of the pressing block move inward under the elastic force of the elastic rope and the elastic force of the elastic airbag itself. At this time, through the fluidity of the gas, the elastic airbag sucks the air inside the inflatable cushion back through the air guide hose, which can facilitate the removal of the telescopic tube.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figure 1 and Figure 2 The technical solution shown in the figure, in order to solve the problem of poor clamp firmness, discloses: a main tube 1 and a telescopic tube 2 installed through the upper end of the main tube 1, wherein a threaded connection section 3 is provided on the outer side of the upper end of the main tube 1, and the inner lower end of the locking nut 4 is threadedly connected to the upper end of the main tube 1 through the threaded connection section 3. The outer diameter of the telescopic tube 2 is smaller than the inner diameter of the main tube 1, and the telescopic tube 2 and the main tube 1 are both cylindrical in shape.

[0032] In the embodiment, the outer diameter of the telescopic tube 2 is smaller than the inner diameter of the main tube 1. The telescopic tube 2 can be inserted into the interior of the main tube 1, thereby supporting the eyewash station and facilitating the use of the eyewash station by the staff. At the same time, the dual pipe arrangement of the main tube 1 and the telescopic tube 2 improves the structural strength of the device and prevents the clamp from being easily damaged.

[0033] Example 2:

[0034] like Figures 1-6 The technical solution shown, in order to solve the problem that the lifting height of the clamp is fixed and cannot be flexibly adjusted, discloses: a locking washer 5 is provided at the upper end of the main tube 1, and the locking washer 5 is located between the locking nut 4 and the telescopic tube 2, and the lower end of the telescopic tube 2 is provided with a stable pressing mechanism and a tightening socket 6, and the tightening sockets 6 are opened at the upper end of the locking nut 4, and the number of tightening sockets 6 is four, and the tightening sockets 6 are provided inside the tightening sockets 6. The lower end of the locking washer 5 is conical, and a longitudinal opening 8 is opened on the right side of the locking washer 5;

[0035] In the embodiment, the upper end of the main tube 1 is provided with a threaded locking washer 5 that cooperates with the locking nut 4 and has a taper and an opening; the side of the locking nut 4 is provided with four tightening holes 6 with a diameter of 6.5 mm, and the outer diameter of the telescopic tube 2 passes through the locking nut 4 and the locking washer 5 and enters the inner hole of the main tube 1. The upper end surface of the inner part of the locking nut 4 contacts the upper end surface of the locking washer 5, and the tapered lower end of the locking washer 5 is inserted into the inner hole of the main tube 1. When the locking nut 4 is screwed into the main tube 1, the upper end surface of the locking washer 5 is pressed downward by the locking nut 4. Because the lower end of the locking washer 5 is tapered, due to the principle of force decomposition, the force on the locking washer 5 is decomposed into downward The force and the force perpendicular to the central axis, under the action of the decomposition force, and because the locking washer 5 has a longitudinal opening 8, the diameter of the locking washer 5 tends to become smaller, and the inner surface of the locking washer 5 hugs the telescopic tube 2, so that the position of the telescopic tube 2 is fixed, which can play a role in a stable fixation. When adjusting the height, insert the 6mm diameter knob rod 7 into the tightening hole 6 on the locking nut 4, rotate it counterclockwise to loosen the locking nut 4, and then insert or pull the telescopic tube 2 downward or upward to reach the desired height, and then rotate the locking nut 4 clockwise to fix the telescopic tube 2, so that the lifting height can be adjusted, which is convenient for the staff to use;

[0036] Example 3:

[0037] like Figure 2 and Figure 7 The technical solution shown in the figure, in order to solve the problem of poor stability of the clamp, discloses: the outer bolt of the main tube 1 is installed with a fixed bin 9, and the interior of the fixed bin 9 is fixedly installed with an elastic airbag 10, and the inner side of the elastic airbag 10 is fixedly installed with a pressure block 11, and the outer side of the pressure block 11 is provided with a secondary stable anti-slip mechanism, the secondary stable anti-slip mechanism is provided with a limiting groove 13, and the limiting groove 13 is opened on the inner wall of the fixed bin 9, and the upper and lower ends of the pressure block 11 are fixedly installed with limiting blocks 12, and the connection mode of the limiting block 12 and the limiting groove 13 is a sliding connection, and the limit block 12 and the fixed bin 9 are connected. An elastic rope 14 is fixedly installed between the main body tube 1 and the main body tube 1. The shape of the pressure block 11 is inclined, and the upper end position of the pressure block 11 corresponds to the lower end of the telescopic tube 2. The pressure block 11 and the elastic airbag 10 form a pressed structure. An air guide hose 15 is installed through the right side of the elastic airbag 10, and an inflatable cushion 16 is installed through the upper end of the air guide hose 15. The shape of the inflatable cushion 16 is cylindrical, and the outer side of the inflatable cushion 16 is fixedly installed on the inner wall of the main body tube 1, and an anti-slip pad 17 is fixedly installed on the inner side of the inflatable cushion 16, and the inner side of the anti-slip pad 17 corresponds to the outer wall of the telescopic tube 2, and the shape of the anti-slip pad 17 is cylindrical;

[0038] In the embodiment, when adjusting the height, if the telescopic tube 2 is inserted into the main tube 1, when the telescopic tube 2 is displaced to the relative position of the bottom of the main tube 1, the pressing block 11 is squeezed by the bottom of the telescopic tube 2. Due to its own inclination, when squeezed by the telescopic tube 2, it moves along the limiting groove 13 toward the inside of the fixed compartment 9 through the limiting block 12, and at the same time squeezes the elastic airbag 10 and stretches the elastic rope 14. At this time, the elastic airbag 10 is squeezed and the air inside is transported to the inflatable cushion 16 through the air guide hose 15. The inflatable cushion 16 receives the air. The inflated air cushion 16 pushes the anti-slip pad 17 to squeeze and support the telescopic tube 2. As the telescopic tube 2 moves downward, the exposed portion of its upper end becomes less. At the contact position between the telescopic tube 2 and the main tube 1, that is, under the restriction of the upper end of the main tube 1, if the telescopic tube 2 is subjected to left and right impact forces, the bottom of the telescopic tube 2 is likely to generate left and right offset forces, resulting in the coaxiality of the telescopic tube 2 and the main tube 1 being offset. This structure prevents the telescopic tube 2 from being offset left and right, thereby ensuring the coaxiality of the telescopic tube 2 and the main tube 1.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
