Description

Technical Field

[0001] This utility model relates to the technical field of valve stem removal devices, and in particular to a valve stem puller. Background Technology

[0002] In today's automotive maintenance and repair field, valve stem installation is a frequent and important operation. With the continuous growth of car ownership, the demand for an efficient and safe valve stem puller is becoming increasingly prominent.

[0003] Currently available valve stem pullers on the market have many problems. The most significant defect is the general lack of a lever structure, which means that operators often need to exert a lot of force to complete the installation, resulting in low installation efficiency. In addition, the existing installation tools are not designed to protect the rim and valve stem. During installation, improper operation can easily cause scratches on the rim and valve stem, which not only affects the appearance of the rim and valve stem, but may also reduce their service life and performance to some extent.

[0004] Therefore, a valve puller is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a valve puller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A valve puller, further comprising:

[0008] A handheld handle, one end of which is provided with a mounting groove;

[0009] The connector is rotatably connected in the mounting groove, and the end of the connector away from the handle is provided with an internal thread groove for connecting the valve stem;

[0010] The mounting head is fixedly connected to the hand handle and is used to abut against the wheel hub.

[0011] To further reduce wear on the wheel hub, preferably, a support seat is fitted onto the mounting head.

[0012] For ease of installation and fixation, preferably, a limiting ring is provided on the mounting head, and one end of the support base abuts against the limiting ring.

[0013] Preferably, the connector is connected to a rotating shaft, and the connector is rotatably connected to the mounting groove via the rotating shaft.

[0014] For ease of handheld use, preferably, the length of the handheld handle is 230-270mm, the length of the connector is 35-45mm, and the length of the support base is 20-30mm.

[0015] To prevent it from falling off, preferably, the handle is provided with anti-slip texture.

[0016] Compared with the prior art, the present invention provides a valve puller, which has the following advantages:

[0017] This invention uses a connector to temporarily limit and fix the valve stem. Then, the support on the mounting head temporarily fixes the hand lever to the wheel hub, protecting the wheel rim and valve stem from scratches. By pressing down the hand lever, the valve stem can be quickly pulled out using a lever. This process is labor-saving and fast, effectively improving work efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example:

[0024] Reference Figure 1-3A valve stem puller further includes: a hand handle 1, one end of which is provided with a mounting groove 101; a connector 2, rotatably connected to the mounting groove 101, the end of the connector 2 away from the hand handle 1 having an internal thread groove for connecting a valve stem; a mounting head 3, fixedly connected to the hand handle 1, the mounting head 3 being used to abut against a wheel hub, a support seat 4 being sleeved on the mounting head 3, a limit ring 301 being provided on the mounting head 3, one end of the support seat 4 abutting against the limit ring 301; a rotating shaft 5 being connected to the connector 2, the connector 2 being rotatably connected to the mounting groove 101 via the rotating shaft 5; the hand handle 1 having a length of 230-270mm, the connector 2 having a length of 35-45mm, the support seat 4 having a length of 20-30mm, and the hand handle 1 having anti-slip texture.

[0025] This device uses a handheld handle 1 with a length of 250mm, a connector 2 with a length of 40mm, and a support base 4 with a length of 25mm. Figure 2 In the state shown, the overall length of the handheld lever 1 and the connector 2 is 290mm.

[0026] When the support base 4 is fitted onto the mounting head 3, one end contacts the limiting ring 301, and the other end is slightly longer than the end of the mounting head 3. At this time, the distance between the support base 4 and the axis of the hand handle 1 is between 20-30mm. The support base 4 is preferably made of rubber.

[0027] The operator quickly locates the valve stem on the wheel hub, aligns the puller connector 2 with the valve stem, and takes advantage of the fact that the connector 2 can rotate flexibly in the mounting groove 101 via the rotating shaft 5. The operator quickly adjusts the angle of the connector 2 so that its internal thread groove is aligned with the valve stem. The operator slowly rotates the connector 2 clockwise to make it tightly connected with the valve stem. During this process, a certain amount of axial pressure can be applied to ensure a firm connection, but excessive force should be avoided to prevent damage to the valve stem. The operator quickly aligns the support seat 4 of the mounting head 3 with the wheel hub so that one end of the support seat 4 accurately abuts against the limiting ring 301. Then, the operator smoothly presses the mounting head 3 against the surface of the wheel hub.

[0028] Then check the contact between the support seat 4 and the wheel hub to ensure that the support seat 4 fits the wheel hub well, providing good protection and support, and preventing the wheel rim from being scratched during subsequent operations.

[0029] The operator then firmly grasps the handle 1 with both hands, utilizing the good friction provided by the anti-slip texture on the handle 1 to ensure a stable grip. Applying even downward force vertically, the operator uses the lever principle to generate a large pulling force, quickly pulling the valve stem from the hub through the connector 2. During the operation, it is important to observe the working status of the puller. If any abnormalities are found, such as loose connector 2 or displacement of support seat 4, the operation should be stopped immediately and readjusted.

[0030] After pulling out the valve stem, you can remove it from connector 2.

[0031] This utility model, through the setting of the connector 2, can temporarily limit and fix the valve stem. Then, through the support seat 4 on the mounting head 3, the hand lever 1 is temporarily fixed to the wheel hub, protecting the wheel rim and valve stem from scratches. Then, by pressing down the hand lever 1, the valve stem can be quickly pulled out by lever. This process is labor-saving and fast, and can effectively improve work efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
