Description

Technical Field

[0001] The utility model belongs to the technical field of tensioners and relates to a tensioner, in particular to a novel tensioner. Background Art

[0002] A tensioner is a device that maintains the proper tension on the timing belt and timing chain, preventing them from skipping due to being too loose or from being damaged due to being too tight. The tensioner and guide rail together form a tensioning system.

[0003] The roller of the tensioner will wear out due to friction after long-term use. When it needs to be replaced later, the tensioner is often fixed with bolts, which makes it inconvenient to replace and repair it later. Summary of the Invention

[0004] The purpose of the utility model is to provide a new tensioner which is easy to replace in order to solve the above problems existing in the prior art.

[0005] The purpose of the present utility model can be achieved through the following technical solutions: A new tensioner, comprising a tensioner body and a base, the tensioner body comprising a bracket, a roller and a rotating shaft, characterized in that the base is provided with a mounting groove for mounting the tensioner body, the base is symmetrically provided with locking mechanisms on both sides relative to the mounting groove, the locking mechanism is composed of a locking rod and a reset spring, the base is provided with a movable hole for the locking rod to move, the locking rod is provided with a limiting part, the base is provided with a movable space for the limiting part to move on the side relative to the movable hole, and the lower end of the bracket is provided with a locking hole that matches the locking rod.

[0006] In the above-mentioned novel tensioner, the return spring is arranged in the movable space and between the limiting portion and the base.

[0007] In the above-mentioned novel tensioner, a limit pull block is provided on the locking pull rod.

[0008] Compared with the prior art, the utility model can quickly disassemble the tensioner by cooperating with the provided locking mechanism and the locking hole, making it convenient for later replacement and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic cross-sectional structural diagram of the present utility model.

[0010] In the figure, 1. tensioner body; 2. base; 3. bracket; 4. roller; 5. rotating shaft; 6. mounting slot; 7. locking mechanism; 8. locking rod; 9. return spring; 10. movable hole; 11. limiting part; 12. movable space; 13. locking hole; 14. limiting pull block. DETAILED DESCRIPTION

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, the new tensioner includes a tensioner body 1 and a base 2. The tensioner body 1 includes a bracket 3, a roller 4 and a rotating shaft 5. The base 2 is provided with a mounting groove 6 for mounting the tensioner body 1. The base 2 is symmetrically provided with locking mechanisms 7 on both sides of the mounting groove 6. The locking mechanism 7 is composed of a locking rod 8 and a reset spring 9. A movable hole 10 for the locking rod 8 to move is provided on the base 2. A limiting portion 11 is provided on the locking rod 8. An active space 12 for the limiting portion 11 to move is provided on the base 2 and on the side relative to the active hole 10. A locking hole 13 cooperating with the locking rod 8 is provided at the lower end of the bracket 3.

[0013] In further detail, the return spring 9 is disposed in the movable space 12 and between the limiting portion 11 and the base 2 .

[0014] To elaborate further, a limiting pull block 14 is provided on the locking rod 8. During installation, the limiting pull block 14 is first pulled to allow the locking rod 8 to enter the movable hole 10, and then the tensioner body 1 is installed into the installation groove 6. Then the limiting pull block 14 is released. The limiting block is reset under the action of the reset spring 9 and connected to the locking hole 13, thereby completing the installation.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as tensioner body 1, base 2, bracket 3, roller 4, rotating shaft 5, mounting slot 6, locking mechanism 7, locking rod 8, return spring 9, movable hole 10, limiting portion 11, movable space 12, locking hole 13, and limiting pull block 14, the use of other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
