[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0018] Reference Figure 1-Figure 3 A slide bar type straight slide potentiometer, comprising a body 1, a slide groove 6 is provided on the upper surface of the body 1, a slide bar 2 is fixedly installed horizontally in the slide groove 6, a slide seat 3 is slidably sleeved on the slide bar 2, the left and right side walls of the slide seat 3 are respectively in sliding contact with the left and right groove walls of the slide groove 6, and a push rod 4 is fixedly installed vertically on the upper surface of the slide seat 3;

[0019] The slide 3 is provided with an installation cavity, a mounting plate is fixedly installed in the middle of the installation cavity, spring rods 5 are fixedly installed on the left and right side walls of the installation plate, a plurality of locking grooves 7 are equidistantly provided on the left and right groove walls of the slide 6, and a through hole for the end of the spring rod 5 to pass through is provided on the left and right side walls of the slide 3, a slot is provided on the surface of the push rod 4, a plug rod 8 is slidably inserted in the slot, a force-bearing rod 9 is fixedly installed on one end of the plug rod 8 outside the slot, and the plug rod 8 is connected to the push rod 4 through a telescopic component, and the telescopic component includes a sleeve arranged on the plug rod 8 The telescopic spring 13 on the top, the two ends of the telescopic spring 13 are respectively fixedly connected with the force-bearing rod 9 and the push rod 4, two round rods 10 are fixedly installed on the lower surface of the force-bearing rod 9, two sliding openings 11 are opened on the upper surface of the slide seat 3, a fixed plate is fixedly sleeved on the spring rod 5, and an inclined plate 12 is fixedly installed on the surface of the fixed plate, the bottom ends of the two round rods 10 pass through the two sliding openings 11 respectively, and the surfaces are respectively against the inclined surfaces of the two inclined plates 12, and the surface of the force-bearing rod 9 is bonded with an anti-skid layer, and the material of the anti-skid layer is rubber;

[0020] When it is necessary to adjust the gear, you only need to push the force-bearing rod 9 by hand to move it in the direction of the push rod 4. At this time, the telescopic spring 13 will shrink, and the surfaces of the two round rods 10 will slide in contact with the inclined surfaces of the two inclined plates 12 respectively. Then, under the action of the pressure, the two spring rods 5 will shrink together, and their ends will move out of the two locking grooves 7 respectively, thereby releasing the lock of the slide 3. At this time, you can control the movement of the slide 3 to adjust the gear position. After moving to the appropriate gear position, release the force-bearing rod 9. The force-bearing rod 9 will quickly move and reset under the elastic potential energy of the telescopic spring 13, so that the pressure applied by the two round rods 10 to the two inclined plates 12 will disappear, and then the ends of the two spring rods 5 will be respectively inserted into the two locking grooves 7 corresponding to their own positions, thereby locking the position of the slide 3 again.

[0021] A safety component is provided on the surface of the push rod 4, and the safety component is used to limit the movement of the force-bearing rod 9. The safety component includes a mounting seat 14 fixedly mounted on the surface of the push rod 4, a mounting rod horizontally fixedly mounted in the mounting seat 14, and a limiting rod 15 rotatably sleeved on the mounting rod. Two torsion springs 16 are sleeved on the push rod 4, and the two ends of the torsion spring 16 are fixedly connected to the mounting seat 14 and the limiting rod 15 respectively;

[0022] In the initial state, the limiting rod 15 will be in a horizontal state with the body 1, and its end away from the mounting seat 14 will correspond to the surface of the force-bearing rod 9. At this time, if the force-bearing rod 9 is pushed to move in the direction close to the push rod 4, the force-bearing rod 9 cannot move due to the restriction of the limiting rod 15, so as to avoid the unlocking of the slide seat 3 due to the staff accidentally touching the force-bearing rod 9, thereby changing the gear position, which can play a safety effect;

[0023] When it is necessary to release the lock on the slide seat 3, it is necessary to first manually control the limiting rod 15 to rotate so that its end no longer corresponds to the surface position of the force-bearing rod 9, thereby releasing the restriction on the force-bearing rod 9, and then push the force-bearing rod 9 to move. Then, when the force-bearing rod 9 moves and resets under the elastic potential energy of the telescopic spring 13, the limiting rod 15 will also quickly rotate and reset under the elastic potential energy of the torsion spring 16, and its end will correspond to the surface position of the force-bearing rod 9 again, thereby restoring the effect of restricting the movement of the force-bearing rod 9.

[0024] When the gear is adjusted, the force-bearing rod 9 only needs to be pushed by hand toward the push rod 4. At this time, the surfaces of the two round rods 10 will respectively slide in contact with the inclined surfaces of the two inclined plates 12. Then, under the action of the pressure, the two spring rods 5 will shrink together, and their ends will respectively move out of the two locking grooves 7, thereby releasing the lock on the slide 3. At this time, the movement of the slide 3 can be controlled to adjust the gear position. After moving to the appropriate gear position, the force-bearing rod 9 is released, and the ends of the two spring rods 5 will respectively insert into the two locking grooves 7 corresponding to their own positions, thereby locking the position of the slide 3 again. The locking between the spring rod 5 and the locking groove 7 is extremely firm and stable, which prevents the slide 3 from moving due to the influence of external forces.

[0025] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
