Detailed Description
The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1-3.
Example 1: a long-stroke linear module comprises a base 5 and a screw rod 13, wherein a bottom cover 10 and a connecting seat 2 are respectively arranged on two sides of the base 5, and two ends of the screw rod 13 are respectively movably connected with the base 5 and the connecting seat 2; the outer end part of the connecting seat 2 is connected with a motor 1, a coupler 3 is arranged in the connecting seat 2, and one end of a screw rod 13 is inserted into the connecting seat 2 and is in driving connection with the motor 1 through the coupler 3; form spout 19 in the base 5, the bottom surface of spout 19 is equipped with two guide ways 20, install guide rail 7 in the guide way 20, every guide rail 7 sliding connection has year thing slide 8 and two at least support slides 6, these two support slides 6 are located the both sides of carrying thing slide 8, two are carried and are connected with between the thing slide 8 and carry thing slider 7, the middle part of carrying thing slider 7 is equipped with screw thread perforation 18 and with lead screw 13 threaded connection, be connected with supporting slide 4 between the support slide 6 that corresponds on the support slide 6 on a guide rail 7 and another guide rail 7, supporting slide 4's middle part is equipped with and goes up the perforation 17 with lead screw 13 complex, lead screw 13 passes perforation 17 and laps in supporting slide 4, supporting slide 4 and the thing slider 7 of carrying are equipped with the elastic component between.
This technical scheme is at work inception, and two supporting slide 4 are located the both sides of carrying thing slider 7 for auxiliary stay lead screw 13 carries thing slider 7, base 5 and connecting seat 2 and also plays supporting lead screw 13's effect. In the working process, when the object carrying slide block 7 slides to approach to a certain supporting slide block 4, the elastic part between the supporting slide block 4 and the object carrying slide block 7 is deformed, and the elastic part between the other supporting slide block 4 and the object carrying slide block 7 is also deformed, the deformation modes of the two elastic parts are opposite, and when the elastic force of the elastic part is greater than the friction force between the screw rod 13 and the supporting slide block 4, the elastic part drives the supporting slide block 4 to move along the guide rail 7; the supporting slide blocks 4 are used for supporting the screw rod 13 in a certain distance adjacent to the object carrying slide block 7, and in the process, when a certain supporting slide block 4 is abutted against the base 5 or the connecting seat 2, the supporting slide block 4 does not move any more; therefore, the object carrying sliding block 7 or the supporting sliding block 4 is supported on the screw rod 13 at any time in the middle of the sliding groove 19 of the base 5, the deformation of the screw rod 13 due to the self gravity is avoided, and the object carrying sliding block 7 can move in a large stroke.
Further, the elastic part is a spring 11, the supporting slide block 4 and the carrying slide block 7 are both slide block units, and the two adjacent slide block units are connected through the spring 11.
The elastic part is selected as the spring 11, so that the elastic part can generate pulling force or pushing force when deformed, and the use is convenient. The resilient member may also be a gas spring rod.
Furthermore, the slider units are provided with mounting holes 16, an expansion link 15 is connected between two adjacent slider units, and two ends of the expansion link 15 are respectively inserted into the mounting holes 16 of the two slider units and fixedly connected; the spring is sleeved outside the telescopic rod 15.
When the spring is used, particularly in the stretching process, the spring can be bent due to the gravity of the spring, so that the balance of the tension is influenced, meanwhile, the inside of the sliding groove 19 is influenced, and in order to avoid the situation that the spring is completely U-shaped, the telescopic rod 15 is arranged in the technical scheme, and the spring is sleeved outside and overlapped; the telescopic rod 15 can adopt a telescopic rod 15 of a television antenna structure. When the two slider units are close to each other, the telescopic rod 15 is shortened by the extrusion of the two slider units, and when the two slider units are away from each other, the telescopic rod 15 is extended by the extension of the two slider units.
Referring to fig. 4, further, each of the guide rails 7 is slidably connected with 2n supporting slide carriages 6, n supporting slide carriages 6 are disposed on each side of the carrying slide carriage 8, and n is a natural number.
During normal operation (the supporting slide 6 is not abutted against the tail cap or the connecting seat 2), two adjacent slide block units keep approximately the same distance, so that the slide block units are approximately uniformly distributed in the sliding groove 19 at intervals. When the sliding groove 19 is very long, in the working process, if the carrying slide block 7 moves towards the tail cover all the time, until the carrying slide block 7 is very close to one of the supporting slide blocks 4, the other supporting slide block 4 is also close to the supporting slide block 4, so that the supporting slide block 4 close to the connecting seat 2 is not available, in order to avoid the phenomenon, the technical scheme is that each sliding rail is provided with 2n supporting slide seats 6 which are respectively and correspondingly arranged at two sides of the carrying slide seat 8, and a spring is also arranged between the two adjacent supporting slide seats 6; in the initial state, the supporting slide block 4 is close to the end cover and the connecting seat 2, and even if the carrying slide block 7 slides to the end part of the guide rail 7, the supporting slide block 4 is enabled to be close to the end cover or the connecting seat 2. n is preferably 1, 2, 3, 4, 5, etc. Currently, due to length limitations, n is preferably 1 or 2.
Furthermore, the sliding groove 19 is respectively provided with a flexible limiting unit 12 at two sides of the guide rail 7.
In order to avoid the support sliding seat 6 from being separated from the guide rail 7, the flexible limiting unit 12 is arranged in the technical scheme, the support sliding seat 6 is limited by the flexible limiting unit 12, and meanwhile, when the support sliding seat 6 collides, the flexible limiting unit is in flexible collision, so that the damage of the support sliding seat is avoided.
Preferably, the flexible stopper unit 12 is a spring damper.
The spring buffer is adopted, the structure is simple, the implementation and the installation are convenient, the supporting slide block 4 is effectively limited, and a hydraulic buffer can be adopted, which is the prior art.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the present description should not be interpreted as a limitation to the present invention.
