Description

Technical Field

[0001] This application relates to the technical field of installation auxiliary devices, and particularly to an installation tool. Background Art

[0002] A common tolerance adjuster includes a stud and a nut connected by threads. The stud and the nut respectively abut against two parts to be adjusted. By screwing the stud, the stud moves axially along the nut, thereby increasing or decreasing the axial length of the tolerance adjuster to adjust the distance between the two parts to be adjusted.

[0003] Generally, a manual screwing method is used to make the screw drive the stud to move relative to the nut to install the tolerance adjuster. However, during the process of manually screwing the screw, it is difficult to control the magnitude of the installation torque, which easily causes the excessive extrusion force between the stud and the part to be installed, further resulting in the part to be installed being lifted and deformed. Utility Model Content

[0004] Based on this, it is necessary to provide an installation tool to solve the problem that during the installation process of the tolerance adjuster, it is difficult to control the magnitude of the installation torque, which easily causes the excessive extrusion force between the stud and the part to be installed, further resulting in the part to be installed being lifted and deformed.

[0005] An installation tool is used to install a tolerance adjuster. The tolerance adjuster includes a stud and a nut connected by threads, and one end of the stud away from the nut is used to abut against the first part to be adjusted, and one end of the nut away from the stud is used to abut against the second part to be adjusted. The installation tool includes a main body part, a pressure sensor and a display screen. One end of the main body part is used to be inserted into the stud and is in limit fit with the stud along its circumferential direction. The pressure sensor is arranged on the main body part and is used to detect the pressure value received by the main body part. The display screen is used to display the pressure value detected by the pressure sensor. Wherein, as the main body part rotates along its circumferential direction, the stud can rotate following the main body part and move axially along the nut to adjust the distance between the first part to be adjusted and the second part to be adjusted along the axial direction of the tolerance adjuster.

[0006] In one embodiment, the installation tool further includes a limiting part. The limiting part is rotationally connected to the main body part along the circumferential direction of the main body part and is used to pass through the second part to be adjusted and connect to the nut. Wherein, as the main body part rotates along its circumferential direction, the limiting part can stop at the second part to be adjusted to limit the rotation of the nut relative to the second part to be adjusted.

[0007] In one embodiment, the limiting part includes a connecting ring and a limiting rod. The connecting ring is rotatably sleeved on the outer periphery of the main body part. The nut is provided with a matching notch corresponding to the limiting rod. One end of the limiting rod is connected to the connecting ring, and the other end passes through the first part to be adjusted and is inserted into the matching notch.

[0008] In one embodiment, a ring groove is formed in the main body portion, and the connecting ring is installed in the ring groove.

[0009] In one embodiment, it is defined that the end of the ring groove close to the tolerance adjuster along the axial direction of the main body portion is the first end, the end far from the tolerance adjuster is the second end, the diameter of the first end is D1, the diameter of the second end is D2, and the inner diameter of the connecting ring is D3, and D1 < D3 < D2.

[0010] In one embodiment, the installation tool further includes an elastic clamp, the inner diameter of the elastic clamp is D4, and D1 < D4 < D3, and the elastic clamp is clamped between the connecting ring and the first end along the axial direction of the main body portion.

[0011] In one embodiment, the display screen is installed on the outer peripheral wall of the connecting ring.

[0012] In one embodiment, the main body portion includes a connecting rod and a handle fixedly connected. The connecting rod is used to be inserted into the stud and is in limit fit with the stud along its circumferential direction, and the handle is used for the user to hold.

[0013] In one embodiment, the connecting rod is configured as an external hexagonal head, and an internal hexagonal hole corresponding to the external hexagonal head is formed in the stud. The external hexagonal head can be inserted into the internal hexagonal hole and is in limit fit with the internal hexagonal hole along its circumferential direction.

[0014] In one embodiment, an external thread is provided on the outer periphery of the connecting rod, and an internal threaded hole is formed in the stud. The connecting rod is threadedly connected to the internal threaded hole.

[0015] Compared with the prior art, in the installation tool provided by the present application, during the process of the user screwing the stud through the main body portion, the pressure F generated by the first part to be adjusted on the stud is transmitted between the stud and the main body portion. By setting a pressure sensor to detect the pressure value received by the main body portion, and by displaying the pressure value received by the main body portion through the display screen, the user can intuitively judge whether the pressure between the first part to be adjusted and the stud exceeds a preset value, so as to avoid excessive pressure between the first part to be adjusted and the stud, resulting in the first part to be adjusted being lifted and deformed.

The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0027] Please refer to Figures 1 to 4 , this application provides an installation tool 100, which is used to install a tolerance adjuster 200. The tolerance adjuster 200 includes a stud 210 and a nut 220 that are threadedly connected, and one end of the stud 210 away from the nut 220 is used to abut against a first part to be adjusted 300, and one end of the nut 220 away from the stud 210 is used to abut against a second part to be adjusted 400. Specifically, the installation tool 100 includes a main body portion 110, a pressure sensor and a display screen 120. One end of the main body portion 110 is used to be inserted into the stud 210 and is in limit fit with the stud 210 along its circumferential direction. The pressure sensor is provided on the main body portion 110 and is used to detect the pressure value received by the main body portion 110. The display screen 120 is used to display the pressure value detected by the pressure sensor; wherein, as the main body portion 110 rotates along its circumferential direction, the stud 210 can follow the main body portion 110 to rotate and move along the axial direction of the nut 220, so as to adjust the distance between the first part to be adjusted 300 and the second part to be adjusted 400 along the axial direction of the tolerance adjuster 200.

[0028] It should be noted that the circumferential direction of the main body portion 110 refers to the direction in which the main body portion 110 rotates one week around its own axis. One end of the main body portion 110 for inserting into the stud 210 and being circumferentially limited and cooperated with the stud 210 means that the end of the main body portion 110 inserted into the stud 210 will not rotate relative to the stud 210 along its own circumferential direction. It can be understood that during the process of the user screwing the stud 210 through the main body portion 110, the pressure F generated by the first part to be adjusted 300 on the stud 210 is transmitted between the stud 210 and the main body portion 110. By setting a pressure sensor to detect the pressure value received by the main body portion 110, and displaying the pressure value received by the main body portion 110 through the display screen 120, the user can intuitively judge whether the pressure between the first part to be adjusted 300 and the stud 210 exceeds a preset value, so as to avoid excessive pressure between the first part to be adjusted 300 and the stud 210, resulting in the first part to be adjusted 300 being lifted and deformed.

[0029] The pressure sensor can be configured as a highly sensitive pressure sensor.

[0030] Exemplarily, in one embodiment, as Figure 1 shown, the first part to be adjusted 300 is configured as the outer panel of the vehicle body roof, the second part to be adjusted 400 is configured as the inner panel of the vehicle body roof, and the tolerance adjuster 200 is used to adjust the tolerance between the inner panel and the outer panel of the vehicle body roof. Among them, the outer panel of the vehicle body roof is used to install the luggage rack 500. In this way, by installing the tolerance adjuster 200 with the installation tool 100, it is possible to avoid excessive pressure between the stud 210 and the outer panel of the vehicle body roof, resulting in the outer panel of the vehicle body roof being lifted, and further resulting in water leakage from the luggage rack 500 into the cockpit.

[0031] The main body portion 110 includes a connecting rod 111 and a handle 112 that are fixedly connected. The connecting rod 111 is used to insert into the stud 210 and is circumferentially limited and cooperated with the stud 210 along its own circumference, and the handle 112 is used for the user to hold.

[0032] Optionally, in one embodiment, the connecting rod 111 is configured as an external hexagon head, and an internal hexagon hole 211 is correspondingly opened in the stud 210 for the external hexagon head. The external hexagon head can be inserted into the internal hexagon hole 211 and is circumferentially limited and cooperated with the internal hexagon hole 211 along its own circumference.

[0033] Or, in another embodiment, an external thread is provided on the outer circumference of the connecting rod 111, and an internal threaded hole is opened in the stud 210. The connecting rod 111 is threadedly connected to the internal threaded hole. In this way, the circumferential limit and cooperation between the connecting rod 111 and the stud 210 can also be realized.

[0034] Please refer to Figures 2 to 4, the installation tool 100 further includes a limiting member 130. The limiting member 130 is rotatably connected to the main body portion 110 along the circumferential direction of the main body portion 110 and is used to pass through the second portion to be adjusted 400 and connect to the nut 220. Wherein, as the main body portion 110 rotates along its own circumferential direction, the limiting member 130 can stop at the second portion to be adjusted 400 to limit the rotation of the nut 220 relative to the second portion to be adjusted 400. It can be understood that the limiting member 130 plays a role in preventing rotation of the nut 220, so as to prevent the nut 220 from rotating along with the stud 210 when the main body portion 110 drives the stud 210 to rotate circumferentially. Thus, when the user screws the main body portion 110, the stud 210 can smoothly engage with the nut 220 in a threaded manner to adjust the distance between the first portion to be adjusted 300 and the second portion to be adjusted 400 along the axial direction of the tolerance adjuster 200.

[0035] The limiting member 130 includes a connecting ring 131 and a limiting rod 132. The connecting ring 131 is rotatably sleeved on the outer periphery of the main body portion 110. The nut 220 is provided with a mating notch 221 corresponding to the limiting rod 132. One end of the limiting rod 132 is connected to the connecting ring 131, and the other end passes through the first portion to be adjusted 300 and is inserted into the mating notch 221. In this way, the main body portion 110 can rotate freely, and the limiting member 130 does not rotate under the stopping action of the second portion to be adjusted 400.

[0036] In one embodiment, the display screen 120 is installed on the outer peripheral wall of the connecting ring 131. Since the main body portion 110 can rotate freely and the limiting member 130 does not rotate under the stopping action of the second portion to be adjusted 400, therefore, installing the display screen 120 on the outer peripheral wall of the connecting ring 131 enables the display screen 120 not to rotate when the user screws the main body portion 110, thus facilitating the user to observe the value displayed on the display screen 120.

[0037] In one embodiment, the main body portion 110 is provided with an annular groove 113, and the connecting ring 131 is installed in the annular groove 113.

[0038] Further, define the end of the annular groove 113 along the axial direction of the main body portion 110 close to the tolerance adjuster 200 as the first end 114, and the end far from the tolerance adjuster 200 as the second end 115. The diameter of the first end 114 is D1, the diameter of the second end 115 is D2, and the inner diameter of the connecting ring 131 is D3. And, D1 < D3 < D2. In this way, the connecting ring 131 can be snapped into the annular groove 113 from the first end 114 and stop at the second end 115. It is convenient for the installation of the connecting ring 131.

[0039] Furthermore, the installation tool 100 further includes an elastic clamp 140. The inner diameter of the elastic clamp 140 is D4, and D1 < D4 < D3. Moreover, the elastic clamp 140 is axially clamped between the connecting ring 131 and the first end 114 along the main body portion 110. It can be understood that the elastic clamp 140 can prevent the connecting ring 131 from disengaging from the first end 114 out of the annular groove 113.

[0040] Specifically, the assembly process of the limiting member 130, the elastic clamp 140 and the main body portion 110 is as follows: First, the connecting ring 131 is snapped into the annular groove 113 from the first end 114 and abuts against the second end 115. Then, the elastic clamp 140 is moved from the first end 114 towards the direction close to the connecting ring 131. The elastic clamp 140 is expanded by the first end 114 and gradually undergoes elastic deformation until the elastic clamp 140 moves into the annular groove 113 and returns to the state before deformation and is clamped between the connecting ring 131 and the first end 114.

[0041] Exemplarily, in one embodiment, the end of the connecting rod 111 close to the handle 112 forms the first end 114, and the second end 115 is located on the handle 112, so that an annular groove 113 is formed at the connection between the handle 112 and the connecting rod 111.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
